Description

device for heat exew nnu

he invention relates to; a device for extracting heat from at least partially aerobically fermenting manure and / or organic waste with at least a heat-absorbing boiler arrangement surrounding, essentially in the Vertical, continuous fermentation room in the area of its upper end can be charged and ends in the area of its lower end at a storage floor and by means of a removal device serving the entire area of the storage floor can be unloaded into a disposal room, according to patent ... (patent application P 27 11 803.2-13).

The basic approach taken with this older proposal has proven, as tests have shown, to be extremely useful. This is in advantageous Way a practically free, so far not used Wirmequelle opened up, which results in excellent economic efficiency. Simultaneously This makes the so-called solid manure process attractive again, which is highly is environmentally friendly.

Make an embodiment of the above-mentioned, not previously published The patent application is intended for the continuous fermentation room (s) through a grid floor be separated from the disposal room, below this grid floor as a removal device one with cutting or

Device equipped with Kratmträger in the form of a slide or turntable should be present. However, the throughput through said grid floor depends depends on many uncertainty factors, so that with arrangements of this type the application process is relatively difficult to control. The mass throughput through the aforementioned grid floor is usually relatively small, so that over time it becomes not inconsiderable Compaction of the fermentation material can occur. The consequence of this is that the existing The proportion of air decreases and then the fermentation process is slowed down or

goose comes to a stop, which in the end results in a poor Heat extraction and incomplete rotting can result.

Starting from this, it is the object of the present invention under To avoid these disadvantages, develop an arrangement of the type mentioned above in such a way that that the Ausbringvorging is geneu controllable and a compaction in the soil area can be effectively counteracted.

This object is achieved surprisingly according to the invention simply by the fact that the dew bottom at least on one side has a free, a Limiting the ejection gap Has edge, and that over the dustpan at least one side conveyor element which acts on the ejection gap over its entire length is arranged.

As a result of the controllability of the application process guaranteed here are advantageously the throughput rate and the required replenishment of fresh material to achieve optimal conditions easily manageable, oo that an optimization of the temperature control is practically guaranteed. The side conveyor cleanly clears the surface of the storage floor and accomplishes it at the same time a loosening of the cleared property, so that this subsequently has a high Iut $ share and can be further fermented in an advantageous manner. At the same time is However, this ensures that on the bottom surface that has been worn away by the side conveyor element Material can slip out of the continuous fermentation chamber, which in turn leads to loosening and thus serves to create good fermentation conditions for the beverage. The inventive Measures therefore lead to a not inconsiderable improvement in efficiency an arrangement of the type mentioned at the beginning the measures according to the invention in purchase u naming construction effort, however, in reasonable limits, so that overall excellent economic efficiency is achieved will.

In an advantageous manner, the side conveyor can be used as a milling worm be designed with a rotary drive for rotation un its axis and with a translation drive is provided for feed in milling direction. Mine auger clearly represents an extremely simple and yet extremely robust side conveyor the noben high performance also an excellent loosening of the promoted Materials results. The screw diameter can expediently be designed so that it increases in the direction of conveyance. This ensures that even with a relatively long conveying distance there is no compression of the conveyed material takes place in the area of the worm threads.

Another useful measure can be that the worm shaft is mounted on both sides. A worm shaft mounted in this way is clearly high Loads grown, so that the height of the column of material located above the screw this means that there are practically no limits.

According to a particularly preferred embodiment with in cross section The worm shaft can at least have a circular fermentation chamber on one side on a Teflonized, preferably at least in the area of its sliding surfaces Be added to the raceway. This measure advantageously results in a high robust and at the same time extremely safe storage. Such a one Storage therefore proves to be expedient, especially on the side of the Schnocke, on which this protrudes into the Durchlaufgérnau @@.

In a further development of the device according to the invention, on the drive side at least one rail parallel to the support ring can be provided on which the worm shaft is stripped by means of a running member mounted thereon. This measure ensures advantageously a relatively simple design of the drive. Appropriately can be designed as a rack rail parallel to the support ring, with at least one pinion of a drive device coupled to the worm shaft cooperates. This allows a simple coupling in an advantageous manner of translation and rotation worm drive accomplish. An expedient embodiment can consist in that on the running element a gear motor is arranged, which on the one hand interacts with the rack Pinion and on the other hand drives the worm shaft.

According to another, particularly preferred embodiment, it can the rotary drive of the worm shaft can be designed so that this also is driven by the pinion cooperating with the toothed rail. Here the drive is particularly simple. Appropriately, the can The worm shaft driving pinion be designed as an impeller between two each rotatably mounted in opposite directions independently of one another drivable racks are arranged. These measures allow in more advantageous Way a stationary arrangement of the drive motors, what in terms of power supply etc. is extremely problem-free.

The difference in speed between the two interacting with the pinion Toothed rails clearly results in a worm shaft translational movement, which can thus be adjusted to practically any desired dimension. Provided both rack rails be driven at the same speed but in different directions, the worm shaft does not move forward, it just gets around its Axis rotated, which can have a very positive effect when starting. According to a particularly simple and therefore preferred embodiment can be between The pinion arranged on the two rack rails is placed directly on the worm shaft be.

In many cases, several, one above the other, can be arranged laterally against one another offset continuous fermentation chambers be provided, especially if it is, for example It is about storing larger, narrow, warm water and such reservoirs by to protect external fermentation rooms against external heat emission.

With arrangements of this type it is therefore particularly useful to if the through-flow fermentation chambers, which are arranged one above the other, have at least one a side conveyor element acted upon ejection gap in connection with one another stand. This shows an orderly application of the top one Proofing room downstream fermentation rooms as well as a repeated loosening of the fermentation Material and thus an optimal temperature control ensured.

Further features and advantages of the invention emerge from the following Description of the drawing in conjunction with the claims.

FIG. 1 shows some exemplary embodiments of the invention on the basis of a two-stage device of the type mentioned at the beginning, FIG. 2 an embodiment of the worm drive in an enlarged, schematic representation and FIG. 3 a Section through a funnel-shaped disposal room.

The system shown in Figure 1 has two stages, each with one Continuous fermentation chamber 1 or 2, in which, as described in the main patent, an exothermic continuous, aerobic fermentation of manure and / or other organic waste is carried out. The upper continuous fermentation chamber 1 of the first stage is thereby of Fresh fermentation material is applied at the top, the lower continuous fermentation chamber 2 is the second Stage is in one underneath, here designed as a pit Disposal room 3 emptied. The one taken from the fermentation chamber 1 of the first stage, here Food that has already been fermented with a high level of heat is used for further use downstream fermentation room 2 fed to the second stage.

The heat generated in the continuous fermentation chambers 1 and 2 is respectively delivered to the boiler surrounded by it. For this purpose, the upper continuous fermentation chamber 1 is ring-shaped around a centrally arranged round kettle 4, which is here to improve the heat absorption with a heating coil 5 laid parallel to this in connection which is appropriate approximately from the boiler wall forming the inner fermentation chamber boundary wall and the outer fermentation chamber limitation 6 has the same distance. The one from the continuous fermentation room 1, boiler 4 and heating coil 5, the first stage is supposed to be about hot water preparation to serve. The heating coil 5 is therefore provided with an inflow connection not shown in detail here Mistake. The withdrawal of warm water is expediently carried out from a certain one Storage volume having boiler 4, which is also not detailed here with a shown outflow nozzle is provided. Often you already come with one-step Systems of this type, so that the associated fermentation room directly into the the disposal room located below is emptied. In the present exemplary embodiment is the continuous fermentation room 1, as already indicated above, another Passage room 2 downstream. Tile is long-shaped and a .u-rcxlessermäßib Compared to boiler 4 of the first stage, pre-larger, centrally arranged boiler 7 laid around, de the residual heat generated in the associated continuous fermentation chamber 2 supplied and which is therefore at least protected from cooling down. The great capacity of Armchair 7 can be used as a primary storage tank formed by boiler 4 downstream secondary ooicner used weruenO The armchair 7 is simple for this according to the line with the heat absorption device of the first stage associate. In such a case, the boiler 7 is expediently divided into several approximately equal sizes Subdivided plots, which increases the mechanical strength not insignificantly and at the same time results in a high degree of variability. In the illustrated embodiment the boiler 7, which is surrounded in a ring by the continuous fermentation chamber 2, is intended to generate methane gas Find use as an anaerobic fermentation chamber, for example with the one from the continuous fermentation chamber 2 in the disposal space 3 ejected good can be acted upon, here one is subjected to further residual use. A pump line, for example, can be provided for this purpose which merges into the boiler 7 at 8. The gas outlet is shown schematically at 9 indicated.

The anaerobic digestion starts at temperatures that help the heat generated in the associated continuous fermentation chamber 2 is easily maintained can be, even if already an extensive utilization already in the continuous fermentation room 1 of the first stage has taken place. The pass through the pass around the boiler 7 fermentation chamber 2 accomplished heating of this boiler serving as an anaerobic fermentation chamber has the advantage that the gas produced is not partially used for self-heating of the Boiler is consumed, as in known arrangements for generating Elärgas, but fully available for further use, so that one in more advantageous Way with a relatively small boiler volume. The heat is absorbed in this case directly over the inner boundary wall of the continuous fermentation chamber 2 forming Kettle wall, which is used to enlarge the receiving area approximately with in the vertical extending ribs etc. can be provided. The perimeter of the annular Continuous fermentation room 2 is indicated at 10.

The axes of the Durchlautgarraume 1 and 2 run approximately in the vertical. The lower ends of the continuous fermentation chambers 1 and 2 are each easy by one here inclined storage floor 11 and 12 demarcated, which a filling of the continuous fermentation chambers 1 or 2 with fermentation material.

due to the vertical extension of the continuous fermentation chambers 1 and 2 the fermentation material entered above slips almost automatically, provided that it is in the area the storage floors 11 and 12 a corresponding removal takes place. With such a Withdrawal, the storage floor in question is simply cleared away and that which is recorded in the process Material thrown over an edge of the relevant storage floor. The dust bottom side The limitation of the continuous cooking spaces 1 and 2 is therefore at least in the area of one edge of the respective associated storage floor 11 or 12 so wide open that the storage floor here 11 or 12 is exposed and a free application gap 13 or 14 results. By reaches the discharge gap 13 in the area of the storage floor 11 of the continuous fermentation chamber 1 while the goods cleared from the storage floor 11 over the free outer storage floor edge in the downstream, due to the enlarged diameter of the boiler 6 outer continuous fermentation chamber 2. That of the storage floor 12 of this continuous fermentation chamber 2 cleared material passes through the discharge gap 14 via the free inner one Edge of the storage floor in the downstream fermentation room 2, which forms the disposal room Pit. The outer fermentation chamber limitation 6 of the upper fermentation chamber 1 ends to form the Ejection gap 13 with a corresponding distance above the outer edge of the associated Storage floor 11. The same applies here to the snake 5, which the continuous fermentation chamber 1 practically divided in half. For holding snake 5 and the outer proofing chamber limitation 6 is therefore in the present A portal-like example supported cross beam 15 provided on which these elements with their upper ends can be hung so that their lower ends over without support from below the associated storage floor 11 ends. The boiler 4 can also be on the Ereuzträger 15 to be hung. In the present Ausführungsbei play the boiler 4, however be deposited on the boiler 7 located below, which in turn on a Cross support 16 rests, for example as in the illustrated embodiment rest on a support column 17 or with its ends in suitable wall niches, etc. can.

The inner edge of the storage floor 12 is to form the discharge gap 14 correspondingly lower than the lower edge of the boiler 7.

Since the storage floors 11 and 12 are practical via their respective free edge are cleared to the side, these storage floors themselves do not require any through openings. The storage floor 11 delimiting the upper continuous fermentation chamber 1 can therefore, as shown in FIG Embodiment conveniently formed simply by the upper cover of the boiler 7 will. The diameter of the boiler 7 therefore corresponds to the formation of a sufficient one Storage floor area expediently approximately the outer diameter of the one above it Continuous fermentation chamber 1. The further continuous fermentation chamber 2 delimiting downward Storage floor 12 can for example by a wall projection of the disposal room 3 and practically the entire second stage surrounding MauerlTarks are formed here.

To achieve a controllable output from the continuous fermentation rooms 1 and 2 is above the relevant storage floors 11 and 12, respectively, in the illustrated Embodiment expediently formed by a milling worm 18 side conveyor provided that then the storage floor 11 or 12 clears away on its own goose area and the associated application £; ½clt 1, resp. 14 applied over its entire circumference. For this purpose, the milling worm 18, whose Axis with respect to the associated, here circular storage floor 11 or 12 extends radially, simply set in circulation on an arch of ice, so that with each The entire storage floor area is coated and cleared in the process.

At the same time, this results in a highly desirable loosening up of the cleared Gci, which tends towards a certain compression in the storage floor area good. At the same time, clearing the stowage floor allows for sliding down Material that also experiences a certain degree of loosening. The auger 18 projects beyond the free edge of the respectively assigned in the illustrated embodiment Storage floor 11 or 12, so that a clean ejection is guaranteed. In the area of the free edge of the storage floor, the associated fermentation room delimitation wall is so wide removed that the auger 18 can rotate freely. The same is of course true also for the floor clearance of the heating coil 5.

The working diameter of the auger 18 expediently increases in the side conveying direction closed, so that no compression needs to take place within the screw threads. the here only indicated by their center lines shafts 19 of the milling worm 18 can be designed as an arm supported on one side. In the illustrated embodiment the shafts 19 are expediently mounted in the region of their two ends, so that also the load resulting from a relatively large fermentation chamber height without further ado is coped with.

It is useful to do this in the respective continuous fermentation room 1 or 2 protruding end of the shaft 19 received on a race 20, the for his part in a fixed housing 21 rotatably mounted is. Zin such a thing, formed by a race received in a housing The bearing link is clearly highly insusceptible to contamination and can therefore can easily be brought into contact with digestate. As experiments have shown can be made by a Teflonization of the sliding surfaces of the race 20 or the Housing 21 achieve particularly good sliding properties. In the illustrated embodiment the housing 21 is designed as a separate component. However, it would also be easily conceivable, the one required in the area of the upper continuous fermentation chamber 1 Running ring 20 in a formed by appropriate shaping of the wall of the boiler 4, i.e. to incorporate the housing integrated into the boiler wall. The drive of the milling worms 18 is expediently carried out in the area of the respective continuous fermentation room from the assigned continuous fermentation chamber protruding «end of the shaft 19, i.e. on the one opposite the raceway 20 Page.

In the illustrated embodiment, the shaft 19 is the upper one Passage fermentation chamber 1 assigned auger 18 on the drive side on a through here a slide 30 formed running member received, which in turn on a stationary, Rail 31 parallel to the raceway is slidably mounted. To accomplish the desired advance of the milling worm 18, the carriage 30 can, for example, as Be designed linear motor. To rotate the milling worm 18, about a be provided on the carriage 30 arranged motor. But it would also be conceivable the auger 18 to rotate approximately by the fact that the rail 31 approximately in the area next to its running surface is provided with a toothing, as indicated in FIG. 1 at 32 which is in engagement with a coupled to the associated worm shaft 19 Drive pinion is located. The translational movement of the auger 18 is evidently converted into a rotary movement at the same time. The in Figure 1 illustrated embodiment is the worm drive by a On the slide 30 arranged gear motor 33 accomplished, on the one hand one for translational movement of the milling worm 18 with the toothing 32 of the rail 31 in engagement pinion 34 and on the other hand for rotating the auger 18 drives a further pinion 35, which here is connected to one on the worm shaft 19 arranged pinion 36 cooperates. The drive pinions 34 and 35 can thereby be advantageously put into operation independently of one another, so that, for example When starting up, the speed of the auger 18 can first be increased, before the translational movement begins, which is evident in the start-up process relieved. The power can be supplied, for example, by means of a power rail indicated at 37 be accomplished by a button, not shown here, of the geared motor 33 is tapped. The busbar 37 can easily be through a permanently installed cable 38 be connected to a switch box 39, etc.

The one in FIG. 1 in the area of the lower continuous fermentation chamber 2 assigned The worm drive shown here does not require a grinding rail, etc. As the drawing clearly shows, the worm shaft 19 is in the area here Its inner bath opposite the raceway 20 is ultimately a running light Pinion 40 gekop) clt, which is located between two each with a corresponding ring gear 41 provided rails 42a and 42b is located. Each with one with the pinion 40 cooperating toothed ring 41 provided rails 42a and 42b are in a housing 43a or 43b rotatably mounted.

When the rails 42a and 42b are rotated in opposite directions in each case In the direction of rotation, the pinion 40 rolls on the rails, as is illustrated in FIG. 2 42a or 42b. Insofar as the two rails 42a and 42b are aligned with opposite, but rotate at the same high speed, the pinion 40 and thus also the The milling worm 18 coupled to it is set in rotation, a translational movement However, it is not yet taking place. As soon as the speeds of the rails 42a or 42b differ from one another, this difference is caused by a translational movement balanced. An arrangement of this type is therefore also advantageously possible an increase in the speed of the milling worm 18 before the start of the translational movement. For this purpose, only the speed of the two rails 42a and 42b is uniform boot up.

To drive the rails 42a and 42b are in the illustrated embodiment In each case individual motors 44 and 45 are provided, which are advantageously arranged in a stationary manner could be. The motors 44 and 45 are included in the illustrated embodiment In each case one output pinion 46 or 47 is provided, which is provided with an associated further Toothed ring 48a and 48b of the rails 42a and 42b cooperate. Of course but would also be, for example, a friction wheel coupling, etc. between the drive motors and the rails 42a and 42b are conceivable. A friction wheel drive is known to be extreme not susceptible to dirt. In the illustrated embodiment, the pinion 40 is direct placed on the worm shaft 19. But it would also be easily conceivable, for example two juxtaposed pinions to be provided, which are driven by the worm shaft 19 receiving bridge are interconnected. In one embodiment of this Art could, for example, be arranged upstream of the worm shaft 19, so that practically any one you want Ratio or reduction achievable were.

To act on the two-stage arrangement shown here, as indicated at 50 in FIG. 1, a PuinD line is provided, which here Arrangement to be charged with manure directly with a stable from which the Manure is to be removed, couples. The pump line 50 is temporarily underground relocated. In the illustrated embodiment, the pump line 50 is at the installation level introduced into the chair 7 and from here approximately centrally through the upper boiler 4 pulled up.

The pump line 5C advantageously extends through the inner one Race 20 of the upper auger 18, so that the trajectory of this auger remains unaffected by this. At the same time, a the fermentation material transported through the pump line is preheated to a certain extent, so that the fermentation process then starts relatively quickly and strongly. In the illustrated In the exemplary embodiment, the pump line 50 penetrates the lower continuous fermentation chamber 2 roughly transversely to the direction of passage. To avoid a build-up of fermentation material a cover 51 provided with suitable sliding surfaces can therefore be provided be.

The aerobic fermentation requires sufficient air access to the Fermentation material. The outer fermentation chamber limits 6 and 10 are therefore, as already in Main patent described as grids provided with suitable air passage slits educated. The Gärraumunlfang is expedient in each case from several, for example 6 or octagonal panel elements set up next to each other. These table elements can expediently have about a circumferential frame, the blind-like through spaced, sclrXg inwardly inclined slats is filled. Through this surrender sellbafter Weis @ obviously schrög after inhen flOlt Deflection surfaces, so that there is no resistance from obon slipping I; a - al Jlactically is opposed.

To achieve a certain slip aid, the individual board elements be moved up and down, as in Figure 1 annand with the fermentation room boundary 10 of the lower continuous fermenter 2 coupled hoisting gear 52 is indicated.

The fermentation material that has passed through both continuous fermentation chambers 1 and 2 ends up finally in the disposal room formed here by the pit 3. This can for example, provided with a gate 53 selenium, so that about a removal by means of a front loader etc. is possible. But it would also be a flood evacuation without further ado conceivable. For this purpose, the disposal space is indicated, for example, via one indicated at 54 Line can be acted upon with floating liquid, for example floating dung. For discharge the resulting suspension a discharge channel 55 is provided, which is about can be acted upon by means of a pumping station not shown here. The floor the pit forming the disposal space is shown in FIG. 1 with one leading to the discharge channel 55 provided sloping downward slope, so that the floating liquid introduced at 54 detected material automatically flows to the discharge channel 55. In the illustrated embodiment the material removed from the pit 3 is to be transferred to the boiler 7 for further anaerobic fermentation are fed. For this purpose, the discharge channel 55 is simple with a boiler branch line to be provided, which opens into the boiler 7, as indicated at 8. The emptying of the boiler 7 can turn by means of a trap not shown here into pit 3.

The measures according to the invention are not only evident at two-stage systems of the type described above are advantageous, but can be It is also advisable to use it in single-stage systems, as it is an orderly one and controllable fermentation output from the fermentation chamber and thus a precisely controllable one Temperature control and the avoidance of undesired compression in arrangements of any kind are desired. In a single-stage system, for example, the here the upper continuous fermentation chamber 1 assigned auger 19 directly into one below request located pit of the type shown in Figure 3. The one shown here, The pit, also designated by 3, is funnel-shaped, which can be seen in in he c¼emnentleerung 'has a particularly positive effect. on the edge 56 of such Pit can be offset about a support frame 57 on which about the required Boiler etc. is added.
