    Device for drying compressed gas and compressor installation provided with such device.
    The present invention relates to a device for drying compressed gas.
    More specifically, the invention is intended for drying compressed gas from a compressor.
    Dryers of the rotary drum type are already known which are filled with a regenerable drying agent, the drying agent being rotated alternately through a drying zone through the rotation of the drum, wherein the drying agent is used to dry compressed gas, and a regeneration zone wherein the drying agent is regenerated by contacting it with a hot gas.
    By regeneration is meant here the process in which a moisture-saturated or nearly saturated desiccant agent is stripped of the absorbed or adsorbed moisture by contacting it with a regeneration gas that will drain the moisture from the desiccant. The drying agent can then be used again for drying.
    Because the drum rotates, a regenerated desiccant will end up in the drying zone and a saturated desiccant in the regeneration zone.
    A disadvantage of such a dryer is that the separation between the different zones is not guaranteed and that leaks occur, which makes it possible for regeneration gas to leak to the dried gas.
    Dryers of the type with two separate vessels are also known, the vessels each operating alternatively to dry compressed gas and to be regenerated.
    A suitable system of pipes and valves can be used to switch between the two vessels.
    A disadvantage of such a device is that the slowest process, being drying agent saturation in most cases, will determine the operation and efficiency of the dryer.
    An additional disadvantage of both of the aforementioned known dryers is the fact that fixed volumes are used for the drying and regeneration zones, which cannot be adjusted according to the situation or circumstances this requires.
    The present invention has for its object to provide a solution to at least one of the aforementioned and other disadvantages.
    The present invention has a device for drying compressed gas with an inlet for compressed gas to be dried from a compressor and an outlet for dried compressed gas, which device comprises a number of vessels filled with a regenerable drying agent and a controllable valve system connecting the above-mentioned inlet and outlet to the above-mentioned vessels, the device comprising at least three vessels, the above-mentioned valve system being such that at least one vessel is always regenerated, while the other vessels dry the compressed gas, whereby by controlling the valve system the vessels are in each case successively regenerated.
    The regenerable desiccant or desiccant material can be, for example, silica gel, but another regenerable desiccant also belongs to the possibilities of the invention.
    By passing the gas to be dried through or along the drying agent, the moisture present will be adsorbed or absorbed by the drying agent and removed from the gas.
    By "valve system" is generally meant a network of pipes and connections to valves or valves that can be adjusted. It is clear that this valve system can take many different forms.
    An advantage is that by using different separate and separate vessels that can serve as drying zone and regeneration zone, no leaks can occur in which, for example, regeneration gas leaks to the dried gas.
    Yet another advantage is that several vessels can dry at the same time, so that each vessel will dry for a longer time and will be regenerated for a shorter time.
    Since the regeneration will proceed faster, this will improve the efficiency of the process. After all, in this way the regeneration process and the drying process will be better aligned so that, when the regeneration of one vessel is done, another vessel will be completely saturated.
    An additional advantage is that when several barrels are used, for example six, eight or more, the number of barrels that is regenerated and the number of barrels that dries can be selected on the basis of external parameters, such as the humidity or the temperature of the air to be dried or environmental parameters.
    Moreover, it is possible to temporarily close or disconnect one or more vessels from the device, so that maintenance or repair to or replacement of the relevant vessel or desiccant is possible without having to shut down the entire device.
    The regeneration of the vessel can be done by means of a regeneration gas that can be tapped from the compressed gas, whether or not before it has been dried. It is also possible that a separate circuit with regeneration gas is used for regeneration.
    Preferably the compressed gas from the compressor is first sent to a cooler before it is sent to the drying vessels, the cooler being part of the device or of the aforementioned compressor.
    This has the advantage that drying of a cool gas will be better. Moreover, the desiccant will remain cooler, so that it will be better able to absorb or adsorb moisture from the gas.
    According to a preferred feature of the invention, the vessels are cooled before or after they are regenerated, whereby by controlling the valve system each vessel successively either: - dries, regenerates and is cooled; or - dries, is cooled and is regenerated; wherein the valve system is such that one vessel is always cooled, while at least one vessel is regenerated and at least two other vessels dry the compressed gas.
    Since a cool desiccant can better adsorb or absorb moisture, this will improve the efficiency of the device.
    Although the cooling of a vessel can take place before or after its regeneration, the cooling preferably takes place after the regeneration.
    The invention also relates to a compressor installation provided with a compressor with an inlet for compressed gas and an outlet with a pressure line for compressed gas, characterized in that the compressor installation is provided with a device according to the invention for drying the delivered by the compressor flow of compressed gas that is passed through the device for supplying dried gas to a consumer network via the outlet of the device, for which purpose the discharge line connects to the inlet of the device.
    Such a compressor installation will have the corresponding advantages of a device according to the invention.
    With the insight to better demonstrate the characteristics of the invention, a few preferred variants of a device and compressor installation according to the invention are described below as an example without any limiting character, with reference to the accompanying drawings, in which: figure 1 schematically shows a device and a compressor installation according to the invention; figures 2 to 10 schematically represent variants of the device of figure 1.
    Figure 1 schematically shows a compressor device 1 according to the invention, which is provided with a device 2 according to the invention for drying compressed gas originating from the compressor device 1.
    The compressor device 1 further comprises a compressor 3 with an inlet 4 for compressed gas and an outlet 5 with a pressure line for compressed gas.
    A cooler 6 is provided downstream of the compressor 3 for cooling the compressed gas before it is sent to the device 2.
    It is not excluded that the cooler 6 forms part of the device 2 according to the invention instead of being part of the compressor device 1.
    The outlet 7 of the cooler 6 is connected to the device 2.
    The device 2 further comprises a number of vessels 8, in this case four vessels 8a-d. It is clear that it is not excluded that the device comprises three, five, six, seven, eight or more vessels 8.
    In this case, two vessels 8a, 8b will dry, while one vessel 8d will be cooled and one vessel 8c will be regenerated.
    However, this is not always the case. The number of vessels 8 that dry, be cooled and regenerated can vary over time. For example, when the regeneration proceeds faster from drying or when the cooling of the vessel 8d is complete, this vessel 8d can already start drying.
    The vessels 8 are filled with a regenerable drying agent, such as, for example, silica gel. The desiccant will be able to absorb or adsorb moisture, for example water or water vapor, from a moist gas passed through the vessels 8.
    The vessels 8 are preferably formed by extruded profiles. As can be seen in the figure, the vessels have two connections 9 for supplying and discharging gas, the connections 9 being located at the opposite ends of the profile. In this way the gas must travel a long way through the vessel 8 and thus through the drying agent.
    The device 2 is provided with an adjustable valve system 10, which in this example is designed in the form of one or more blocks 11a, 11b which are connected to the vessels 8, which consist of a network of pipes 12 with valves 13 or valves.
    In this case there are two blocks 11a, 11b which are as good as identical and which are connected at the opposite ends of the vessels 8.
    The controllable valve system 10 is designed such that it will be possible to control this valve system 10 such that one vessel 8c is regenerated, one vessel 8d is cooled and two vessels 8a, 8b will dry, for example by appropriately switching the valves 13.
    This is made possible in the example shown in that the valves 13 are switchable between two different positions. To this end, the device 2 is provided with a control unit not shown in the figures.
    The device 2 is provided with an inlet 14 for compressed gas to be dried at the location of the block 11a, which connects to the outlet 7 of the aforementioned cooler 6 by means of an injector 15.
    The device 2 is furthermore provided with an outlet 16 for dried compressed gas at the location of the other block.
    The device 2 is also provided with a branch line 17 which branches off a part of the hot compressed gas from the compressor 3 to be dried before the gas is sent via the cooler 6, the branched gas via the branch line 17 going to one of the vessels 8c is sent to regenerate this vessel.
    Because this gas is relatively warm, it will be able to regenerate the vessel 8c in an efficient manner by withdrawing the absorbed or adsorbed moisture from the drying agent and removing it.
    This branched gas will then be sent via a feedback line 18 to a cooler 19 and then to the aforementioned injector 15. This feedback line 18 is in this case integrated in the block 11a. It is also possible that this gas is vented instead of being sent again to one of the aforementioned vessels 8.
    The device 2, in particular the blocks 11a, 11b are also designed such that a part of the dried compressed gas can be split off before this gas leaves the device 2 via the outlet 16.
    In the example shown this is done by means of the operation of the valves 13 in the block 11b and the lines 12 provided.
    This split gas will be led to the vessel 8d to be cooled, whereafter the custard is sent from the aforementioned feedback line 18 to the cooler 19 and then to the aforementioned injector 15. It is not excluded that this gas is subsequently vented instead of to the cooler 19 and injector 15.
    The cooler 19 is optional.
    The operation of the compressor device 1 is very simple and as follows.
    The compressor 3 will suck in gas to be compressed via its inlet 4, which gas may possibly contain a quantity of moisture. The compressed gas will leave the compressor 3 via the outlet 5 of the compressor 3.
    Since the gas will heat up during compression, the compressed gas has a higher temperature.
    Therefore, it is controlled via the cooler 6, whereby it is not excluded that a portion of the moisture already condenses and is discharged via a condensate screen.
    Cooled compressed gas is then brought to the inlet 14 of the device, where it is led via the injector 15 to the vessels 8.
    The valves 13 in the block 11a are hereby controlled such that the gas can only end up in the vessels 8a, 8b which dry.
    During the passage in these vessels 8a, 8b, the gas comes into close contact with the drying agent, whereby the moisture present in this gas will be absorbed or adsorbed by the drying agent.
    The dried compressed gas will leave the vessels 8a, 8b and will flow via the lines 12 and valves 13 of the block 11b to the outlet 16 to be discharged to, for example, a consumer network that is not shown in the figures.
    Simultaneously with the drying process taking place in the two aforementioned vessels 8a, 8b, there will also be one vessel 8c that is regenerated, which vessel will contain a saturated or nearly saturated drying agent. This vessel will have previously dried gas.
    To regenerate this vessel 8c, use is made of a regeneration gas, but in this case gas is branched off at the outlet 5 of the compressor by means of the branch line 17.
    This branch line 17 will branch off a portion of the hot, compressed gas and lead to the block 11b, where the lines 12 and valves 13 ensure that this is led to the vessel 8c to be regenerated.
    This branched gas will flow through this vessel 8c, whereby, by using the compression heat, the absorbed or adsorbed moisture is removed and the drying agent thus dried.
    After its passage through the vessel 8c, the gas is sent via the feedback line 18 from the block 11a to the cooler 19 and combined via the injector 15 with the cooled, compressed gas from the compressor 3.
    It will then be sent to the vessels 8a, 8b which dry and follow the same path as described above.
    In other words: the gas is recovered.
    In this case, but not necessarily for the invention, the fourth vessel 8d will be cooled simultaneously with the drying process and the regeneration process. This vessel 8d will previously have been regenerated with the warm regeneration gas.
    As a result, the regenerated drying agent will have a relatively high temperature.
    Since a cold desiccant is better able to dry than a warm desiccant, it is better for the efficiency of the device 2 to first cool the desiccant before reinserting the relevant vessel 8d for drying.
    The cooling will be done by means of a cooling gas, which in this case concerns the cool, dry compressed gas which is split off at the outlet 16.
    The conduits 12 and valves 13 of the block 11b will ensure that this spliced gas is led to the vessel 8d to be cooled.
    The split gas will flow through this vessel 8d, this gas cooling the drying agent. After its passage through the vessel 8d, the gas is sent through the block 11b via the feedback line 18 to the cooler 19 and combined via the injector 15 with the cooled, compressed gas from the compressor 3.
    In other words: the cooling gas is also recovered in this case, similar to the regeneration gas.
    When one of the gas-drying vessels 8a or 8b is saturated with moisture, it will be necessary to regenerate this vessel, for example vessel 8a.
    By switching the valves 13, it can be ensured that regeneration gas is brought to this vessel 8a by opening the connection of this vessel 8a to the branch line 17 and to the feedback line 18, so that the regeneration can take place according to the process described above. .
    The other vessel 8b that previously dried gas will not yet be saturated and will still be used to dry gas.
    The vessel 8c that was previously regenerated will now be cooled. This is done analogously by appropriately switching the valves 13 so that the cooling gas is led to this vessel 8c.
    Also analogously, the vessel 8d that was previously cooled will now be used to dry compressed gas.
    The switching cycle described above will be repeated continuously, so that each vessel 8 will successively dry, then be regenerated to be subsequently cooled, after which it can be used again to dry gas.
    It is important to note that the control of the valves 13 can be adjusted as a function of the operating parameters and / or the load of the device 2 to optimize the process.
    For example, based on the humidity of the compressed gas leaving the compressor 3.
    It is clear that this control can be done automatically, for example by providing the necessary sensors and controllers.
    Although the vessels 8 as described above are cooled after the regeneration, it is not excluded that the vessels 8 are first cooled before being regenerated.
    Figure 2 shows an alternative embodiment of a compressor device 1 according to the invention.
    The difference with the previous embodiment is that the injector 15 has been replaced by a valve 20 that will control the split flow. The valve 20 is in this case designed as a three-way valve, which will control the ratio between the split partial flows. It is possible that this valve 20 can be controlled automatically with the aid of the aforementioned control or with another control.
    Cooling will also be done in a different way. In this case use is made of a part of the gas to be dried which is drawn off after the gas is sent via a possible cooler 6. This drained gas will be used to cool the vessel 8d, whereafter this drained gas is fed to the dried compressed gas outlet 16.
    Furthermore, the compressor device 1 and its operation are analogous to the embodiment described above.
    Figure 3 shows yet another alternative embodiment, which is approximately the same as the first embodiment, but in which case the branch line 17 will branch off gas after the compressed gas has passed through the cooler 6. Included in the branch line 17 is a heat exchanger 21 which is coupled to the aforementioned cooler 6 to heat up the gas again by means of the heat extracted from the compressed gas.
    Figure 4 shows a fourth embodiment, in which in this case three vessels 8a, 8b, 8c will dry at all times and one vessel 8d will be regenerated. In other words, no separate vessel 8 is provided for cooling.
    The regeneration gas is split off from the dried compressed gas by means of a branch line 22 before it leaves the device 2 via the outlet 16.
    Since the dried compressed gas in the cooler 6 is cooled, it will be necessary to provide a heating element 23 in this branch line 22 which will heat up the split gas before it is sent to the vessel 8d to be regenerated.
    This separation line 22 and the heating element 23 are in this case, but not necessarily, both integrated in the block 11b.
    The split gas can be brought to a temperature by means of the heating element 23 such that it is warm enough to be able to regenerate the drying agent.
    After this regeneration phase of the vessel 8d, a cooling of the vessel 8d can be achieved by switching off the heating element 23 for some time so that the split gas is not heated before it is led to the vessel 8d.
    The split gas will then act, as it were, as a cooling gas, so that cooling of the vessel 8d is achieved before it is used for drying gas.
    The heating element 23 can, for example, remain switched on for fifty minutes to ensure the regeneration of the vessel 8d and then be switched off for ten minutes, so that the split gas can cool the vessel 8d.
    In certain cases, depending on the temperature, operating conditions and the requested pressure dew point, it is possible to bring the split gas through the heating element 23 to a temperature such that it is just warm enough to be able to regenerate the desiccant, but also not warmer. In this way it can be ensured that no cooling of the vessel 8d is needed after regeneration and / or that the heating element 23 must be temporarily switched off.
    After passing through the vessel 8d, the split gas is vented by means of a blow-off valve 24. In other words, this gas will not be recovered.
    Just upstream of the blow-off valve 24, an expansion valve 25 is provided. This expansion valve can also be provided upstream of the heating element 23 in the branch line 22.
    Figure 5 shows yet another alternative embodiment, which is similar to the compressor installation 1 of Figure 1, but in which the injector 15 has been omitted in this case.
    Instead, the cooler 19 has been replaced by a booster blower 26.
    The booster blower 26 will ensure that the cooling gas and the regeneration gas are sent back to the inlet 14 via the feedback line 18.
    By a booster blower 26 is meant pressure-increasing means such as, for example, a screw blower, a centrifugal blower, a compressor, and a tooth or rotor blower or the like.
    The cooler 6 is displaced so that it is flat upstream of the inlet 14 of the device 2, so that this cooler includes both the gas from the compressor 3 and the cooling gas and the regeneration gas which via the feedback line 18 through the operation of the booster blower 26 reflux can cool.
    In Fig. 6 is another alternative embodiment, different from Fig. 1, in that the cooler 9 is absent and in which the cooler 6 has been moved to a location downstream of the injector 15 and upstream of the inlet 14,
    Furthermore, the block 11a is also designed differently, wherein the valves 13a are switchable between three positions.
    The valve 13 can connect the connection of a vessel 8 to either the inlet 14 for the supply of gas to be dried, so that the relevant vessel 8a or 8b can dry the gas, or to the feedback line 18 for feedback of the cooling gas when the relevant vessel 8d is cooled, or with a return line 27 for returning the regeneration gas when the relevant vessel 8c is regenerated.
    The return line 27 will return the regeneration gas to a point upstream of the injector 15. In this case, therefore, a separate line is provided to return the regeneration gas and the cooling gas to the inlet 14.
    At the location where previously the cooler 6 was located, a control valve 28 is now arranged which in this case takes the form of a two-way valve, whereafter the aforementioned injector 15 and the cooler 6 are placed successively. The control valve 28 has the same function as the valve 20 and will be able to control the split flow or, therefore, how much of the compressed gas coming from the compressor 3 will be split off by the split pipe 17. This control valve 28 will also be able to be controlled automatically analogously to the valve 20. by means of the aforementioned control or another control.
    Figure 7 shows a variant according to 'full flow regeneration', wherein the full flow rate from the compressor 3 is directed to the vessel 8c to be regenerated.
    The cooler 6 of figure 1 is hereby moved to a location downstream of the injector 15, so that the compression heat can be used for the regeneration.
    The block 11b is designed as in figure 6, with valves 13a with three positions, wherein in this case also a return line 27 is provided, as in figure 6, so that the cooling gas and the regeneration gas can be led via a separate line to the inlet 14 .
    The feedback line 18 for the regeneration gas and the return line 27 for the cooling gas both lead to the injector 15, from where the cooling gas and regeneration gas are led to the cooler 6 before being sent to the vessels 8a and 8b.
    The compressor device 1 as shown in Fig. 8 is analogous to the compressor device 1 of Fig. 7, only a booster blower 26 is provided in the return line 27 to ensure that the cooling gas can be led via the return line 27 to the cooler 6. The use of the booster blower 26 makes the injector 15 superfluous.
    Figure 9 shows another alternative to Figure 7. In this case the return line 27 is absent, but the cooling gas will be vented.
    For this, the compressor device 1 is provided with blow-off valve 2A and a silencer 29. The injector 15 has been omitted.
    A final variant shown in Figure 10 differs from the variant in Figure 1 in that the cooler 19 is absent and in that the cooler 6 has been moved. This has the advantage that one cooler 19 can be saved.
    Although in the examples shown above the gas used for the regeneration is branched off or split off from the compressed gas, it is not excluded that the device 2 according to the invention is provided with a separate circuit with a regeneration gas for the regeneration of the above-mentioned at least one vessel 8 that is regenerated.
    This has the advantage that the type of gas, the temperature, humidity and other parameters of this gas can be chosen as optimally as possible to achieve good regeneration.
    The examples shown only show some of the conceivable combinations in terms of the origin of the cooling gas and regeneration gas. It is clear that even more combinations are possible, all of which belong to the possibilities of the invention.
    The examples shown also always show four vessels 8a-d, but it is not excluded that there are only three vessels 8 or more than four vessels 8.
    Although a preferred embodiment comprises four vessels 8, one vessel 8 being cooled, one vessel 8 being regenerated and two vessels 8 drying, other combinations are also possible.
    For example, it is possible that the number of vessels 8 that dries, is regenerated and cooled is variable in time, depending on the speed of regeneration and cooling of vessels 8.
    It is furthermore also possible that there are six vessels 8, one of which is always cooled, two vessels 8 are always regenerated and three vessels 8 always dry.
    It is also possible that there are eight vessels 8, of which one vessel 8 is always cooled, at least two vessels 8 are always regenerated and at least four vessels 8 always dry.
    The eighth vessel 8 can then optionally be switched as a vessel 8 that is being regenerated, or as vessel 8 that will dry that gas, depending on what is needed at that time.
    This is an additional advantage of the invention: in all the examples shown, it is always possible to choose how many vessels 8 must always be regenerated and / or cooled and how many vessels 8 must always dry.
    The present invention is by no means limited to the embodiments described as examples and shown in the figures, but such a device and compressor installation according to the invention can be realized according to various variants without departing from the scope of the invention.
