    The invention relates to a device for solids separation
    Gases with a raw gas chamber that can be connected to a raw gas channel at the top and to a discharge funnel at the bottom, and with at least one filter arranged in the raw gas chamber, the flow channel of which is surrounded by a filter jacket and can flow through from bottom to top is connected to a clean gas chamber.
    Simple devices for separating solids from gases have one
    Raw gas chamber on, in which the lamella filters are arranged in rows (DE 297 16 683 U1), so that the raw gas sucked into the raw gas chamber at the top by vacuuming the raw gas chamber flows down along the lamella filter and passes through a lamella separator to pass the lamella filter to the bottom of the lamella filter scheduled clean gas channels to be deducted.
    Because of the downward flow of the raw gas within the raw gas chamber, a part of the solids load can already be collected in a discharge funnel which closes the raw gas chamber downwards. The one at the
    The remaining solid matter accumulating on the lamellar filters is then blown off by the lamellar filters at intervals with the aid of compressed air pulses with which the lamellar filters are acted upon in the opposite direction to the clean gas flow, so that they can be discharged through the discharge funnel. However, it is disadvantageous that separate pressure lines are provided for blowing off the lamellar filters and that these known filter devices only become larger in a complex manner
    Filter systems can be connected.
    In addition, it is known (EP 0 172 538 A2) to attach the clean gas chamber laterally to the raw gas chamber which can be charged with raw gas from above, the horizontally aligned filters arranged one above the other in vertical rows in the raw gas chamber in openings in the partition between the raw gas chamber and the clean gas chamber are used, so that in turn a top-down flow of raw gas can be used with an advantageous solids separation. However, such a filter arrangement is for a modular one
    No expansion planned.
    The invention is therefore based on the object of providing a filter device which can be composed of modules which are identical to one another in a streamlined manner in order to adapt to the filter performance required in each case.
    Starting from a device for separating solids from gases of the type described at the outset, the invention achieves the stated object in that the filter passes through a raw gas chamber which is open through the top and bottom
    Clean gas line is connected, which opens into the clean gas chamber laterally adjacent to the raw gas chamber.
    Since the raw gas chamber is open at the top and bottom and above by a
    Clean gas line for the filter is penetrated, there are advantageous
    Prerequisites for a modular design, because such a raw gas chamber can flow through the raw gas from top to bottom due to its open design at the top and bottom, without endangering the discharge of the clean gas from the filter. The clean gas can through the raw gas chamber across
    Clean gas line passing through the raw gas flow is sucked out of the flow channel formed by the filter into the clean gas chamber, which connects laterally to the raw gas chamber. In the simplest case, the raw gas chamber can thus be connected at the top to the raw gas duct and at the bottom to the discharge funnel. However, it is also possible to expand the device by means of a correspondingly designed raw gas chamber attached to the top and / or bottom of this raw gas chamber, without in particular for the
    Raw gas routing to have to create additional, complex pipe connections between the individual raw gas chambers.
    Since the raw gases flow around the clean gas line running across the raw gas flow, it is advantageous if the one passing through the raw gas chamber
    The clean gas line has a flow cross-section that is favorable for a downward crude gas flow around the filter, because then the pressure losses can be kept comparatively small. For this purpose the
    Clean gas line form a tent-roof-shaped ceiling, which on the one hand ensures an even flow distribution of the raw gas on both sides of the
    Clean gas line supports and on the other hand creates simple manufacturing conditions.
    If filters in the form of vertical filter cartridges arranged in a row are used, it is advisable to hold the filter cartridges in a slide-in part which engages in a guide associated with the bottom of the clean gas line, so that the filter cartridges are close to the slide-in position of the slide-in part
    Bottom openings. The insertion part with the filter cartridges forms in this
    In the case of an easily exchangeable unit that only has to be removed from the guide or inserted into the guide.
    As already explained, the raw gas chamber according to the invention with the filters used is an advantageous prerequisite for adapting the
    Filter device to different filter outputs. To enlarge the
    Filter performance and thus the filter area can namely at least two
    Raw gas chambers are arranged one above the other, the upper one to the
    Raw gas duct and the lower one to be connected to the discharge funnel to a
    To be able to use raw gas exposure to all filters with advantageous solids separation downwards, regardless of the particular embodiment of the filter. Filter inserts can not only be used in the form of filter cartridges, but also, for example, in the form of filter plates, bellows or filter bags. It is only necessary to ensure that the clean gas cleaned after passing through the filter jacket moves upwards in a flow channel formed by the respective filter into those connected to the filter at the top
    Clean gas line flows.
    The subject matter of the invention is shown in the drawing, for example. Show it
    1 shows a modular unit of a device according to the invention for separating solids from gases in a vertical section perpendicular to the clean gas lines,
    2 shows a section along the line II-II of FIG. 1,
    3 shows a device according to the invention composed of such modular units in a schematic section perpendicular to the clean gas lines and
    4 shows a section along the line IV-IV of FIG. 3rd
    The modular unit shown in FIGS. 1 and 2 has a raw gas chamber 1 which is open at the top and bottom and has a rear wall 2, to which a side clean gas chamber 3 adjoins. Within the raw gas chamber 1, filters 4 are arranged from two rows of vertical filter cartridges 5 perpendicular to the rear wall 2, which are connected at the top to a clean gas line 6 running in the longitudinal direction of the row. The clean gas lines 6 provided for each row of filter cartridges 5 pass through the raw gas chamber 1 and are flow-connected to the clean gas chamber 3 through through openings 7 in the rear wall 2.
    Since the raw gas is supplied to the raw gas chamber 1 from above, the
    Clean gas lines 6 flow around outside of the raw gas, as shown in Fig. 1 by the
    Flow arrows is indicated. It is therefore advisable to design the clean gas lines 6 with a flow cross section that is favorable for the raw gas flushing. According to the embodiment shown, the clean gas lines 6 have a tent-shaped ceiling 8 for this purpose.
    In order to be able to replace the filter cartridges 5 in rows in a simple manner, the filter cartridges 5 of a row are each inserted in an insertion part 9 which engages in a guide 10 on the underside of the clean gas lines 6. This guide 10 rises in the direction of insertion, so that the filter cartridges 5 in the drawn
    The insertion position of the insertion part 9, with the interposition of a seal 11, being pressed tightly against the bottom 13 of the clean gas line 6 provided with corresponding bottom openings 12, when the insertion part 9 in the front area of the clean gas line 6 is pressed against the bottom 13 of the clean gas line 6, for example using a tension lock 14 designed as a tension lever lock held down. To remove an insertion part 9 with the filter cartridges 5 inserted therein, after opening the door forming the front wall of the raw gas chamber 1, which is not shown for reasons of clarity, only the tension lock 14 needs to be opened and the insertion part 9 with the filter cartridges 5 has to be pulled out of the guide 10.
    The filter cartridges 5 can be charged with compressed air pulses for filter cleaning. For this purpose in the clean gas lines 6 to one
    Compressed air reservoir 15 connected pressure lines 16 are provided which have nozzle openings directed towards the bottom openings 12.
    When using such a modular unit to manufacture a
    In the simplest case, the filter device is the raw gas chamber 1 at the top
    Connect the raw gas duct and close it at the bottom with a discharge funnel for the separated solid particles. If a blower is connected to the clean gas chamber 3, raw gas can flow out of the raw gas channel through the
    Raw gas chamber 1 is sucked in from above and passed through the filter cartridges 5 under a solid separation in order to be collected as clean gas in the clean gas chamber 3 and to be discharged from the clean gas chamber 3 via the blower.
    As the exemplary embodiment of a filter device composed of a plurality of modular structural units according to FIGS. 3 and 4 shows, modular structural units according to FIGS. 1 and 2 can be combined both one above the other and next to one another to form a larger filter device. The raw gas chambers 1 with the clean gas chambers 3 connected on the rear side can be placed one on top of the other, whereby with regard to the raw gas flow there is a continuous flow shaft through the stacked raw gas chambers 1, which ensures that the filter cartridges 5 of all the raw gas chambers 3 arranged one above the other are supplied with raw gas the uppermost raw gas chamber 1 connected raw gas channel 17 is supplied. Since the lowest raw gas chamber 1 is closed at the bottom by a discharge funnel 18, the solid particles separated from the raw gas stream can be discharged through the discharge funnel 18 into a collecting container 19.
    The extraction of the clean gas from the one above the other
    Clean gas chambers 3 can be carried out in different ways depending on the respective specifications. It is thus possible to provide a clean gas channel which is continuous through the clean gas chambers 3 and to which the individual clean gas chambers 3, each of which are closed, or to connect the individual clean gas chambers 3 one above the other in order to connect only the uppermost or lowermost clean gas chamber 3 to one
    Connect the suction fan. For side-by-side raw gas chambers 1, a common
    Raw gas channel 17 for supplying the filter cartridges 5 with raw gas and a common discharge funnel 18 for the separated solid particles can be provided, regardless of whether only one row or more rows of raw gas chambers 1 arranged one above the other are provided. in the
    3 and 4, the raw gas chambers 1 are assembled in pairs side by side and one above the other to form a filter device.
    The invention is of course not limited to the exemplary embodiments shown with filters 4 in the form of filter cartridges 5 arranged in rows. For example, it is possible to use 5 filter bags instead of the filter cartridges or instead of the filter cartridges 5 arranged in rows
    Use filter plates or bellows filters. There are no restrictions with regard to the filter selection if only it is ensured that the
    Raw gases flow around the filters 4 from top to bottom and, after passing through the filter jacket, flow upward within the flow channel enclosed by the filter jacket into the clean gas line 6 connected to the respective filter 4.
