    Biodigestor of fluid treatment and its operation procedure 5 Technical field of the invention
    The present invention corresponds to the technical field of fluid treatment, in particular the biodigesters formed by a containment chamber of said fluids in which anaerobic and complete digestion of the organic matter diluted in water is generated,
    10 producing gas and fertilizers. Background of the Invention
    At present there is a tendency to use biodigesters, as well as a broad development of them.
    Biodigesters perform anaerobic fermentation of organic wastes diluted in water. The result of this process are very profitable products, each in its own way.
    20 Firstly, the biodigestion process produces organic fertilizers with a high nutrient content that result in fertilizers of much greater capacity, while biogas is generated from the anaerobic fermentation of organic matter itself, which is a high methane content. very interesting source of energy, especially due to
    25 the constant increases in the price of a barrel of oil, as well as the awareness of a necessary conservation of the environment.
    Thus, a higher quality organic fertilizer and a considerable energy source are achieved, while reducing the pollutant load due to the 30 animal or human feces and eliminating bad odors.
    There are several types of digesters, depending on the anaerobic effluent purification system, which are basically divided into two types, depending on whether the flow is discontinuous or continuous.
    35 In the case of discontinuous flow biodigesters, they are charged only once and the fluid is removed when the gas has stopped producing, only at that time the organic matter is renewed.
    image2
    5 This type of discontinuous biodigesters is the simplest and is used when the availability of organic matter is limited or intermittent and usually consists of a cylindrical chamber, although there are also elongated ones and, they present several drawbacks, including the fact that the Biogas production is not continuous. They are not valid if there is the possibility of a new load in a shorter period of time, as
    10 until the first load has not finished the fermentation process, it cannot be removed to introduce a new load. The amount of matter to be treated determines the size of the chamber.
    In the case of continuous flow biodigesters, loading is carried out continuously and
    15 tend to be more oriented to sewage treatment. The organic matter introduced in the same, advances through the interior of the chamber from the point of entry to an exit point of the same, investing enough time to completely carry out the fermentation process. They are usually made up of several independent cells. These systems tend to become clogged, so that internal agitation of the fluid is necessary.
    20 The length of the chamber through which the fluid flows is conditioned by the volume of fluid to be fermented and the time it must remain in it, so the size of these biodigesters is a conditioning aspect.
    25 There are also semi-continuous biodigesters that are loaded spacedly, every certain period of time that can be once a day, every certain number of days ... and is used when the availability of organic matter meets a constant periodicity.
    Reference documents 30 ES8106687 A1, ES0268374 U and ES2529380 A1 can be mentioned as an example of the prior art.
    Reference document ES8106687 A1 refers to improvements in anaerobic digester systems to produce combustible gas from organic waste, characterized in that each system comprises a digester tank having an inlet end designed to receive an aqueous suspension of fluid containing the organic waste and an outlet end from which the aqueous suspension of the tank is discharged,
    image3
    whose tank comprises a flexible air-tight membrane and an outlet thereof located therein into which the gas passes as it emerges from the aqueous suspension.
    It also comprises means for introducing the aqueous suspension into the tank through said inlet end and means for extracting the aqueous suspension from the outlet end after passing through the tank, thermal transfer means submerged in the suspension contained in the nearby tank from its bottom and running parallel to the direction of flow in a substantial part of the length of the tank to heat the suspension at a temperature that results in anaerobic digestion of organic waste to produce the necessary agitation of the suspension only by convection thermal, with agitation being carried out mainly in transverse directions to the flow direction of the aqueous suspension through the tank to thereby improve the gas generation process without hindering the orderly flow of the aqueous suspension through the tank.
    We see in this case that it is a continuous flow system, in the fluid the tank must travel from beginning to end with the same temperature characteristics. This generates a low effectiveness because as the fluid progresses through the tank it is fermenting and therefore its conditions and characteristics change, so it requires different conditions of bacterial activity at all times. This activity is determined by the temperature of the fluid generated by the exchanger and constant throughout the tank.
    Reference document ES0268374 U, refers to an improved digester for anaerobic manure fermentation, and of the type intended for use in an energy self-supply plant in agricultural holdings from the cattle excrement established to obtain biogas, which It comprises a generally tapered shape derived from an ovoid supported on the ground in such a way that its longitudinal axis is in an upright position and its more widened pole or end is in a lower position, thereby preventing the formation of the solidified layer of manure. which usually occurs at the top level of the product contained in conventional digesters; because the digester is constituted from a thermal insulating wall composed of two sheets or layers of fiberglass and polyester with interposition of a mass of high insulating coefficient, preferably polyurethane.
    image4
    In this case it is a digester with discontinuous flow, which must be given a specific ovoid shape so that it meets the digestion conditions in the most effective way.
    5 Reference document ES2529380 A1 refers to an in-line continuous digester or separate continuous mixing tunnel for the production of biogas that allows the biodigestion of all types of waste, coming from the agribusiness, livestock, solid waste, etc., consisting in an entrance chamber, an interior of the biodigester that has adequate conditions for the generation of biogas, as well as dimensions
    10 sufficient according to the needs, a dome or vault where the generated biogas accumulates, an exit chamber, guides or positioning rails of the wagons and, semi-automatic beating devices, formed by a crank, an endless shaft and a coupling.
    15 In this case it is a biodigester with little fermentation capacity, since the material is introduced into the wagons that are moving through the interior of the tunnel, which must have an important length if you want to accommodate several wagons and they remain inside the tunnel the time necessary for its fermentation to take place.
    20 Likewise, in this case agitators are used formed by a mechanism that rotates inside the fluid generating the shake thereof. However, due to the aggressiveness of the fluid medium, corrosion is generated that hinders the proper functioning of this type of agitator with movement.
    25 We see, then, that the biodigesters are very conditioned to the type of flow that circulates through them to determine the form of the same, being therefore very difficult to be able to vary the use of a digester from a continuous flow to a discontinuous one, if the conditions of flow contribution or if we had a fluid whose contribution could be continuous or discontinuous depending on certain periods. There is therefore a very strong dependence on the form
    30 of the biodigester for the type of flow that then circulates through it.
    In the case of continuous biodigesters, which are the most widespread, they are also characterized by the need for large areas of facilities and high hydraulic retention times, caused to some extent also by the fact of using the activity of the bacteria of the same mode throughout the tank, regardless of
    image5
    different fluid needs depending on the point of the tank in which it is located or depending on the specific needs they have. Description of the invention
    5 The fluid treatment biodigester, of which they comprise a chamber for the containment of the fluids to be treated, inside which it presents means for loading said fluids as well as means for exiting them, which is proposed here, presents the chamber divided into at least two consecutive sectors communicated by a section of
    10 open union, where these sectors have a minimum level and a maximum level of filling, one of the sectors being the initial sector of the flow, where the loading means are and, another of the sectors the final sector of the flow in which they are the outlet means and, where each of the sectors comprises heating means, a lower agitator and an upper agitator.
    15 Said heating means and the agitators of each sector are independent and in addition the agitators are formed by interconnected conduits so as to circulate the fluid between the different sectors.
    20 According to a preferred embodiment, the heating means are formed by a heat exchanger which in each sector is arranged at a height less than that of the minimum filling level, and where the lower agitator of each sector is arranged at a height greater than that of the heat exchanger and less than that of the minimum level of filling and the upper agitator is arranged at a height greater than that of the maximum level of filling.
    According to a preferred embodiment, the lower agitator of at least one sector is connected to the upper agitator of said sector. In a preferred embodiment, the lower agitator of at least one sector is connected to the upper agitator of a consecutive sector and according to a preferred embodiment, the lower agitator of at least one sector
    30 is connected to the upper agitator of a sector other than the corresponding one in a row.
    According to another aspect, the chamber has an orthopedic shape and according to another preferred embodiment, the chamber has a cylindrical shape, the initial sector of the flow being located at the perimeter and the final sector of the flow located in the center.
    image6
    In a preferred embodiment, the cover is at least partly rigid, formed of plastic.
    According to a preferred embodiment, the cover is at least partly flexible, formed by EPDM or canvas.
    5 In this report, in turn, a continuous operation procedure of a fluid treatment biodigester as previously defined is presented, in which the charging means continuously charges the fluid in the chamber or at such intervals which ensures that the fluid level is maintained between a maximum filling level and
    10 a minimum level of filling and where, maintaining a level of fluid between said maximum and minimum levels of filling, the fluid is circulated in a continuous manner within the digester through different sectors, where each of them presents conditions of temperature and agitation determined and independent.
    In this report, a method of discontinuous operation of a fluid treatment biodigester as proposed is also proposed, in which the charging means make a single initial fluid charge in an amount such that the level thereof is between a maximum level of filling and a minimum level of filling, where each of the sectors has independent temperature and stirring conditions
    20 that are modified at certain time intervals to provide the desired conditions in each sector at each given moment, where the fluid outlet means perform their complete extraction at the end of the treatment of the fluids introduced in an initial charge.
    With the biodigestor of fluid treatment and the procedures of continuous and discontinuous operation thereof proposed here, a significant improvement in the state of the art is obtained.
    This is so it is a biodigester that allows to have any geometric shape, thanks to
    30 the structuring by sectors and, in addition, the formation material of the chamber can be any as long as it guarantees the tightness of the content.
    It also allows flexibility with respect to the type of cover, since it can be rigid, elastic
    or a combination of the two. 35
    image7
    All this allows this biodigester to be versatile and can be used with both continuous and discontinuous operation. This makes it suitable for treatment in areas with continuous organic matter supply always, always discontinuous or even for those in which continuity or discontinuity varies over time or seasonally.
    5 This biodigester also works as a gasogen as quality biogas is generated.
    Thanks to the design of this biodigester, the permanence of organic matter is guaranteed in
    10 inside the time necessary for fermentation and anaerobic digestion is controlled in all parts of it.
    To do this, the operation of the heating means as well as the stirrers is controlled, in order to apply the temperature and agitation parameters in each form zone.
    15 independent and according to the needs of each. In addition, by having strict control of temperature and agitation, gas and digestate production can be accelerated or delayed as appropriate. Each of the zones or sectors can be independently monitored and make the desired corrections to achieve the desired result.
    20 Another advantage is that inside the biodigester there is no mechanical or electrical device, because the agitators themselves are formed by pipes that collect or expel liquid, so that they are not formed by mobile mechanisms that are more susceptible to the effects of corrosion due to the environment in which they are submerged.
    25 Extractions or contributions of any liquid or gas that may be necessary to contribute to fermentation can be carried out. And it can work with different levels inside, and can also serve as a digestate deposit.
    30 It is therefore an effective and versatile biodigester, valid for any mode of operation of the fluid, which also optimizes the space needed to carry out the fermentation and can be carried out in any way, it is easier to find the one that best suits the available space.

    10 Detailed description of a preferred embodiment of the invention
    In view of the figures provided, it can be seen how in the preferred embodiments of the invention proposed below, the treatment digester 1
    15 of fluids presented here, are those that comprise a chamber 2 for the containment of the fluids to be treated, inside which it presents loading means 3 of said fluids as well as outlet means 4 thereof.
    Chamber 2 of this biodigester 1 is divided into at least two consecutive sectors 5
    20 communicated by an open junction section, where said sectors 5 have a minimum level 6 and a maximum level 7 of filling, one of the sectors 5 being the initial sector 5.1 of the flow, where the loading means 3 are, and another of the sectors the final sector 5.2 of the flow in which the outlet means 4 are, and, where each of the sectors 5 comprises heating means, a lower agitator 9 and an upper agitator 10.
    25 The heating means and the agitators 9, 10, of all sectors 5 are independent and the agitators 9, 10, are formed by interconnected conduits so that the fluid circulates between the different sectors 5.
    As can be seen in Figures 1 and 2, in this first preferred embodiment of the invention, the fluid treatment biodigester 1 has a chamber 2 formed by two consecutive communicated and independent sectors 5, in this case formed by the sector initial 5.1 and the final sector 5.2.
    In this first preferred embodiment of the invention, as shown in Figures 1, 2 and 7, the heating means are formed by a heat exchanger 8 which in each sector 5 is arranged at a height less than that of the minimum level 6 filling. Likewise, the lower agitator 9 of each sector 5 is arranged at a height greater than that of the heat exchanger 8 and less than that of the minimum filling level 6 and the upper agitator 10 is arranged at a height greater than that of the maximum level 7 filling.
    image10
    5 In this first preferred embodiment of the invention, the lower agitator 9 of each sector 5 is connected to the upper agitator 10 of the other consecutive sector 5 that forms the chamber 2. In the drawings, said connection and the pump which is not shown are shown. It circulates the fluid through it.
    The chamber 2 of the biodigester 1 of this first preferred embodiment of the invention has an orthopedic shape, with a rectangular plan and section, as can be seen in Figures 1 and 2 and the cover 11 is flexible, formed by an impermeable fabric.
    A second preferred embodiment of the invention is presented herein, in which the fluid treatment biodigester 1 is similar to that of the first preferred embodiment of the invention, with the proviso that in this case it is formed by a chamber 2 divided into a number of sectors 5 greater than two, which we determine as a value of “n” sectors, all arranged consecutively one after
    20 another in a single row, so that the chamber has an orthopedic shape with rectangular plan and section, as can be seen in Figures 3, 6 and 7.
    One of the sectors 5 of this chamber 2, as in the first preferred embodiment of the invention, is an initial sector 5.1 of the flow located at one end of the
    25 chamber 2, in which the loading means 3 are located, and another of the sectors is the final sector 5.2 "n" at the opposite end of the chamber 2, in which the output means 4 are located. Each of the "n" sectors has heating means formed by a heat exchanger 8, a lower agitator 9 and an upper agitator 10 independent of each other, similar to those of the first embodiment.
    Likewise, in this second preferred embodiment of the invention, the lower agitator 9 of each sector 5 is connected to the upper agitator 10 of another sector 5 of the chamber 2 which in some cases is a consecutive sector and in others not .
    A third preferred embodiment of the invention is also presented herein, where the fluid treatment biodigester 1 is similar to those of the first and


    second embodiment, except in the form of chamber 2, which in this case is formed by a number of sectors "n" greater than two arranged consecutively one after the other and in two rows of communicated sectors 5.
    5 Thus, as shown in Figures 4, 6 and 8, chamber 2 has an orthopedic shape, with rectangular plan and section, where the initial sector 5.1 is at one end of a first row and the final sector 5.2 is in the same end of the second row.
    In this third preferred embodiment of the invention, both the means of
    10 heating formed by a heat exchanger 8, such as the lower agitator 9 and the upper one 10 of each sector 5, are again independent of each other, and in this case, as shown in Figure 8, the upper agitator 10 of each sector 5 of the first row is connected to the upper agitator 10 of sector 5 of the second row adjacent to it. The connection between lower stirrers 9 of these same sectors does not
    15 is represented in the Figures.
    A fourth preferred embodiment of the invention is presented herein, in which the fluid treatment biodigester 1 is similar to the previous ones, except in the form of chamber 2 which in this case is a chamber with a number " n ”of sectors 5 willing
    20 consecutively and in a number "m" of rows, as shown in Figures 5, 6 and 9. In this case the connection between upper 10 and lower agitators 9 is made between consecutive sectors, but is not represented in the Figures.
    A fifth preferred embodiment of the invention is proposed herein, in the
    25 that unlike the four previous embodiments, the chamber 2 has a cylindrical shape, and therefore a circular plan.
    In this fifth embodiment, as shown in Figure 10, the initial sector 5.1 is located in the perimeter of the chamber 2 while the final sector 5.2 is located in
    30 the center of it.
    The heating means formed by the heat exchanger 8, as well as the lower agitator 9 and the upper one 10 of the sectors 5, are all independent of each other. In this case the lower agitators 9 and upper 10 are connected with consecutive sectors not 35. Thus, Figure 11 shows the connection of the upper agitator 10 of the
    image11
    central sector 5.2 with two sectors 5 arranged around it, but not consecutively in the direction of flow.
    Figure 12 shows the biodigester plant 1 of this fifth preferred embodiment of the invention, free of conduits, in order to better understand the flow direction of the fluid.
    The cylindrical fluid treatment biodigester 1, such as that of the fifth proposed embodiment, can also have a different size and with different number of sectors 5. As an example, the plant of two possible biodigesters 1 is provided in Figure 13.1 and 13.2. in a cylindrical shape, of smaller size and smaller number of sectors 5 in the case of Figure 13.1 and of larger size and greater number of sectors 5 than the fifth mode proposed, in Figure 13.2.
    In all the preferred embodiments of the invention proposed, the corresponding chamber 2 further comprises an overflow 12 if necessary and a conduit 13 for the exit of the gases.
    This report also presents a continuous operation procedure of a fluid treatment biodigester as any of those defined in these preferred embodiments of the invention.
    In this procedure the loading means 3 carry out the loading of the fluid in the starting sector 5.1 of the chamber 2 continuously, so that the fluid level is maintained at all times between a maximum level 7 and a minimum level 6 of fill.
    In this way, the fluid circulates continuously through the biodigester 1 through the different sectors 5 of the chamber 2, where each of these sectors 5 has certain and independent temperature and agitation conditions.
    A second method of discontinuous operation of a treatment biodigester 1 is also proposed herein as any of those previously defined in the proposed embodiments.


    In this discontinuous process, the charging means 3 make a single initial fluid charge. The amount of fluid in this initial charge must be such that its level is between a maximum level 7 and a minimum level 6 of filling.
    5 In this procedure, the temperature and agitation conditions of the sectors 5 are independent and are varied at intervals of time, in order to provide the desired conditions in each sector 5 at each given time. Likewise, in this procedure, the outlet means 4 perform the complete extraction of the fluids introduced in the initial charge, when the treatment thereof ends.
    10 With the fluid treatment biodigester and the continuous and discontinuous operation procedures presented here, significant improvements are achieved with respect to the prior art.
    15 Thus it is a biodigester that allows great flexibility in terms of materials and shapes, thus offering greater ease of coupling to the space available for installation. It is also flexible in terms of the type of cover, which can be rigid, flexible or a combination of both.
    20 Likewise, the fact that its operation can be both continuous and discontinuous, favors its installation in any case, regardless of the type of fluid supply and also, its installation is possible in cases where the fluid contribution can vary from continuous to discontinuous depending on the time of year or depending on other periods.
    25 Its design generates a fluid path from an initial sector to a final sector, so that it remains in the biodigester as long as necessary for fermentation. Thanks to the control of the heating and stirring means independently for each of the sectors, the necessary temperature and stirring conditions are provided at all times and it is possible to control both the fluid conditions
    30 as gas production.
    It is therefore a biodigestor of simple, versatile and effective fluid treatment.
