Definitions
- the invention relates to a biogas plant fermenter tank according to the preamble of claim 1 and a method for operating it according to the preamble of claim 22.
- a biogas plant fermenter tank with a service device is known from EP 2 497 822 B1, with a tank interior that is formed by a bottom wall, a continuous side wall and a film roof connected to it in a gas-tight and, preferably detachable manner.
- a substantially liquid, fermentable substrate is accommodated in the tank interior up to a predeterminable fill level.
- the fermenter tank is equipped with a service device that has a service platform as a walkable, flat platform plate that is connected gas-tight to a tank side wall at the top on the one hand and has a roof connection area on the other hand to which the film roof is connected gas-tight.
- a service opening is provided in the platform plate, which can be closed in a gas-tight manner by means of a covering device and through which a diving device, in particular a submersible mixer and/or a feed pump of an injection device, which is height-adjustable on a guide mast, can be moved essentially gas-tight out of the fermenter tank and back into the fermenter tank for maintenance and service work.
- a diving device in particular a submersible mixer and/or a feed pump of an injection device, which is height-adjustable on a guide mast
- a further disadvantage is that if the cover device is removed without further measures, biogas would escape from the area under the platform plate to ensure a gas-tight opening of the service opening.
- a rigid, pipe-like collar to the underside of the service opening in a gas-tight manner, which protrudes into the fermenter vessel interior with a length of at least approx. 60 cm below the substrate surface during operation and thus prevents a seal against gas escaping from the service opening when the cover is open.
- the disadvantage is that such a collar is complex to attach, often buckles due to the load from the substrate flow, which is expensive to repair, and slows down the substrate flow in its area in an unfavorable way.
- the object of the invention is therefore to develop a biogas plant fermenter tank in such a way that the above disadvantages no longer occur and a further object of the invention is to propose a suitable method for operation.
- a biogas plant fermenter tank is claimed with a tank interior which is defined by a bottom wall, a circumferential side wall and a film roof which is connected to the side wall in a gas-tight manner, preferably gas-tight and detachable, and in which a substantially liquid, fermentable substrate is accommodated up to a predeterminable fill level.
- the fermenter tank further comprises a service device which has a service platform as a walkable, preferably flat and/or horizontally aligned platform plate which is connected in a gas-tight manner to a tank side wall, preferably in an upper region as seen in the vertical axis direction, and further has a roof connection region to which the film roof is connected in a gas-tight manner, preferably gas-tight and detachable.
- a service platform as a walkable, preferably flat and/or horizontally aligned platform plate which is connected in a gas-tight manner to a tank side wall, preferably in an upper region as seen in the vertical axis direction, and further has a roof connection region to which the film roof is connected in a gas-tight manner, preferably gas-tight and detachable.
- the platform plate has at least one service opening that can be closed gas-tight by means of a covering device and through which a diving device that is height-adjustable on a guide mast, in particular a submersible mixer and/or a feed pump of an injection device, can be moved essentially gas-tight out of the container interior and back into the container interior for maintenance and service work, wherein the film roof is designed as a supporting air roof with an outer roof skin film and a gas storage film arranged gas-tight under the outer roof skin film as a sub-roof film above the substrate level, as seen in the vertical axis direction.
- the outer roof skin film is preferably kept inflated in a predetermined roof shape, for example by means of a supporting air blower with a predetermined supporting pressure.
- the gas storage foil forms a volume-variable gas storage tank in which the biogas produced is collected and can be expanded towards the outer roof skin foil depending on the gas filling volume.
- the fermenter vessel comprises a gas extraction device, by means of which the gas collected in the gas storage can be discharged and/or withdrawn from the vessel interior via a gas outlet opening into the gas storage, for example by means of a conveying device, such as a pump.
- a gas extraction device by means of which the gas collected in the gas storage can be discharged and/or withdrawn from the vessel interior via a gas outlet opening into the gas storage, for example by means of a conveying device, such as a pump.
- At least one vertical support is provided in the fermenter vessel, which is aligned in the vertical axis direction, preferably at least one vertical central support arranged approximately centrally and/or centrally in the vessel interior, which, preferably starting from the bottom wall, with an upper head part, relative to the vertical axis direction, protruding above a maximum substrate level, wherein the upper head part, preferably the upper end of the upper head part seen in the vertical axis direction, is designed as a belt carrying and belt connecting part, from which a plurality of support belts are stretched above the substrate level to the side wall regions, on which the gas storage film lies when the gas storage is not or only slightly filled with gas, preferably without dipping into the substrate.
- the gas outlet connected to the gas extraction device preferably by means of at least one gas line of the gas extraction device, is arranged, viewed in the vertical axis direction, above the plane of the platform plate and/or above the plane of a container upper edge defined by the side wall upper edge.
- the gas outlet or gas extraction opening from the gas storage unit is always above the substrate level, thus enabling reliable gas removal that is not at risk of permanent blockage even when the container is fully filled, i.e. when the substrate level is at the level of the platform plate and/or the level of the top edge of the container. Since the gas extraction does not take place at the platform plate, no gas volume is required under the platform plate, so that the substrate level can be higher up to the platform plate, which means that the fermenter volume can be better utilized due to the larger substrate volume. In addition, raising the substrate level in this way advantageously eliminates the critical collar that protrudes downwards at the service opening.
- the support itself or a component arranged in the region of the support, preferably directly or indirectly coupled to the support has or forms the gas outlet opening into the gas storage in the region of the upper head part, preferably in such a way that the gas outlet is connected by means of at least one gas line of the gas extraction device, by means of which the gas collected in the gas storage is guided in the direction of the bottom wall and can be extracted from the fermenter container.
- the support extending from the base wall can be tubular and form a gas line of the gas extraction device leading to the base wall, which is led out of the area of the fermenter container on the base wall side, preferably below the base wall and/or in the base wall, either by itself or coupled to at least one other gas line of the gas extraction device.
- the gas outlet is then advantageously formed with little component-intensiveness by an inflow opening formed on the upper head part of the support.
- At least one gas line of the gas extraction device can be arranged on the side of the support, preferably connected to it, which has an inflow opening forming the gas outlet and is led to the bottom wall, where it is led out of the area of the fermenter container on the bottom wall side, preferably below the bottom wall and/or in the bottom wall, either by itself or coupled with at least one other gas line of the gas extraction device.
- a protective hood at a distance and, as seen in the vertical axis direction, above the respective inflow opening provided. This serves in particular as protection against the inflow opening being covered by a lowered gas storage foil of a gas storage tank that is not or only slightly filled and/or to ensure that the gas in the area below the spaced protective hood flows unhindered into the associated gas line via the inflow opening.
- the gas extraction device can optionally have a cleaning and/or maintenance device in the area outside the fermenter container, in particular for separating condensate and/or for flushing the at least one gas line of the gas extraction device, which
- the extracted gas can be fed in via the gas line leading from the fermenter tank.
- a condensate pipe can be attached to the bottom of the support pipe, which drains condensate under the bottom wall via a siphon into a collecting tank. Slightly above the lower end of the support, dewatered biogas can also be fed in via a side connection to the support pipe as a gas extraction opening and led out of the tank area at the side.
- an equally advantageous upper gas outlet can also be provided, in which the gas storage film has or forms the gas outlet opening into the gas storage, preferably in such a way that the gas outlet is connected to the gas extraction device by means of at least one roof-side gas line, by means of which the gas collected in the gas storage is guided in the direction of the roof outer skin film and can be withdrawn from the fermenter container, preferably in the area of the roof outer skin film.
- a roof-side gas line can be provided here, which forms the gas outlet with a lower mouth end in relation to the vertical axis direction and is connected to the gas storage film, preferably above the upper head part and/or in a gas-tight manner, as seen in the vertical axis direction. Furthermore, it is then provided that the roof-side gas line has or forms a primary line section that extends at least in part in the vertical axis direction upwards towards the roof outer skin foil, preferably extending to the highest point or the dome tip of the roof outer skin foil. And here again there are several options for ensuring effective gas extraction starting from the primary line section:
- the primary line section with an upper mouth end, relative to the vertical axis direction, for forwarding the biogas outside the fermenter tank can be connected, preferably gas-tight, to a roof opening in the roof outer skin film, preferably in the area of the dome tip of the roof outer skin film, to which in turn another gas line is connected as a secondary line section for forwarding the biogas outside the fermenter tank.
- the primary line section penetrates the outer roof skin foil, preferably in a gas-tight manner, and is continued with a secondary line section outside the fermenter tank.
- a further gas line is connected to the primary line section, preferably in the region of the dome tip, as a secondary line section, which is guided as an internal gas line, preferably along the inside of the gas outer skin film downwards towards the upper edge of the container and out of the fermenter container, preferably up to the upper edge of the container and there through the roof outer skin film out of the fermenter container.
- connection of the roof-side gas line to the gas storage foil moves up and down depending on the filling level of the gas storage.
- the connected roof-side gas line should be able to follow this gas volume-dependent movement of the gas storage foil with as little force as possible and without restoring forces.
- the roof-side gas line can move with the gas storage foil, preferably essentially without restoring forces, whereby it is preferably provided that the roof-side gas line is designed like a bellows and/or with support rings spaced apart in the longitudinal direction of the roof-side gas line.
- the platform plate has a mounting wall that projects upwards in the vertical axis direction and extends in the area above the plane of the platform plate and above the upper edge of the container, wherein the mounting wall, preferably an upper edge area of the mounting wall in the vertical axis direction, forms at least part of the roof connection area, to which at least a partial area of the gas storage film is connected, so that the mounting wall adjoins the gas storage.
- the mounting wall has or forms the gas outlet that opens into the gas storage, preferably in such a way that the gas outlet is connected by means of at least one gas line of the gas extraction device, by means of which the gas collected in the gas storage can be extracted from the fermenter container.
- the fermenter tank has an injection device which has at least one feed pump by means of which injection liquid can be sucked out, preferably from the substrate of the fermenter tank or from another fermenter tank of the biogas plant, wherein the injection device has at least one injection nozzle element which is fluidly connected to the at least one feed pump and by means of which the injection liquid sucked out by means of the at least one feed pump can be injected into the fermenter tank in such a way that, based on the vertical axis direction, it hits the surface of a floating layer of the substrate from above as a liquid jet and wets it. This ensures that these floating layers can participate in the fermentation process even without being stirred into the substrate. Due to the jagged surface structure of the floating layer, the bacteria in the liquid jet also find a sufficient attack surface for an effective fermentation process with a high biogas yield.
- the injection nozzle element is also held on the mounting wall, preferably held and guided through it.
- the above features and measures can be implemented advantageously and expediently in conjunction with a cylindrical fermenter container, which is why it is preferably provided that the fermenter container has a cylindrical circumferential side wall with a support forming a central support in the cylinder axis.
- the fermenter container has a cylindrical circumferential side wall with a support forming a central support in the cylinder axis.
- other container shapes are also possible.
- the platform plate has an edge frame which projects downwards into the interior of the container and/or dips into the substrate during operation of the biogas plant and which runs around the edge at least on the area of the platform plate which projects into the interior of the container. It is ensured in a particularly simple and reliable manner that gas tightness is still ensured even when the service opening is open and the substrate level is just below the level of the platform plate, with the substrate level in the fermenter tank also still being set high. This advantageously uses the entire contents of the fermenter tank up to the foil roof connection for substrate filling and the associated biogas production, and ensures gas tightness when the service opening is open.
- the edge frame is preferably designed as a rigid, inflexible frame, preferably made of metal. For example, it can only protrude about 5 cm to 20 cm downwards from the platform plate.
- edge frame can conveniently run around the edge of the area of the platform plate that protrudes into the interior of the container and then connect directly to the side wall, possibly also connecting it in a gas-tight manner.
- edge frame could also be provided - at least in sections - in the area of the platform plate that adjoins the side wall, for example in order to form a corresponding stop on the side wall.
- the platform plate can advantageously be designed as a stable metal or stainless steel plate, for example relatively thin with a thickness of, for example, 3 to 5 cm.
- the covering device which closes the service opening in a gas-tight manner can be formed by at least one cover and/or by a mast housing which projects upwards away from the service opening and forms a receiving space for a mast upper part of the guide mast.
- the platform plate is trapezoidal, preferably isosceles trapezoidal, wherein the longer trapezoid base side is connected gas-tight to the top of the container side wall and the platform plate is supported downwards towards the inside of the housing wall by means of at least one platform plate support.
- a method for operating a biogas plant fermenter tank according to one of the above features is claimed in such a way that during biogas plant operation, but at least during the time when the service opening is open, the level of the substrate in the fermenter tank is set so high that the platform plate is at least partially immersed in the substrate on the edge, optionally with an edge frame. This advantageously uses the entire content of the fermenter tank up to the foil roof connection for substrate filling and the associated biogas production, and ensures gas tightness when the service opening is open.

- Platform plate according to Figure 4, and Fig. 6 shows a further exemplary embodiment with a mounting wall of the platform plate extending in the area above the plane of the platform plate and above the upper edge of the container, on which the gas outlet opening into the gas storage tank is formed.
- Figure 1 shows an example of a section through a biogas plant fermenter tank 1 with an example of a service device 2 with a tank interior 3 formed by a bottom wall 4, a circumferential side wall 5 in a cylindrical shape and a film roof 6 connected to it in a gas-tight manner.
- liquid, fermentable substrate 7 is essentially filled in up to the height of the side wall 5.
- the service facility 2 has a service platform as a walkable, preferably flat platform plate 8, as shown in detail in Figure 4 with its lateral gas-tight connection to the side wall 5. Opposite this is a roof connection area 9 to which the foil roof 6 is connected in a gas-tight manner. In the area of the service facility 2, the otherwise dome-like foil roof is indented and, for the sake of clarity, is not shown in this area in Figure 1.
- the platform plate 8 has a large rectangular service opening 10, which can be closed gas-tight using a cover device 11 as shown in Figure 1.
- the cover device 11 here comprises, by way of example, only a cover 12 and a portion of a mast housing 13 which projects upwards above the platform plate 8 and forms a receiving space for the upper part of a guide mast 14 which is pivotably mounted on the base wall 4 in a pivot bearing 15.
- a submersible mixer 17 is held on the guide mast 14 in a height-adjustable manner by means of a cable winch 16, for example. When the cover is open, the submersible mixer 17 can be lifted out through the service opening 10 above the platform plate 8 for maintenance and service work, as shown by way of example in Figure 2.
- the platform plate 8 is designed here as a relatively thin metal or stainless steel plate with a thickness of approx. 5 cm and has an approximately isosceles trapezoidal shape, with the longer trapezoidal base side at the top of the Container side wall 5 is connected in a gas-tight manner.
- the platform plate 8 is supported towards the inside of the housing with platform plate supports 18 (shown only schematically).
- the platform plate 8 has a frame 19 on the edge that projects downwards into the container interior and into the substrate, which frame is designed here as a rigid and inflexible frame.
- the edge frame 19 is preferably connected to the underside of the platform plate.
- edge frame 19 here only runs around the edge of the area of the platform plate 8 that protrudes into the interior of the container and is directly connected to the side wall 5, possibly also in a gas-tight manner.
- the edge frame 19 can also be provided - at least in sections - in the area of the platform plate 8 that adjoins the side wall 5, for example in order to form a corresponding stop on the side wall 5.
- the foil roof 6 is designed as a supported air roof with a roof outer skin foil 20, which blows air 22 with a predetermined supporting pressure into an air space 23 under the roof outer skin foil 20 by means of a supporting air blower 21, whereby the roof outer skin foil 20 is kept inflated in a dome-like roof shape.
- a stable support 28 is arranged centrally and vertically, here as a central support, which has an upper head part 29 projecting above the substrate level 26.
- a plurality of support belts 30 extend from the upper end of this head part 29 and are radiating above the substrate level to the
- the gas storage foil 24 is stretched towards the side wall 5, onto which the gas storage foil 24 rests when the gas storage 25 is not filled with gas or only slightly, and thus does not dip into the substrate 7.
- the gas extraction and gas removal from the gas storage 25 takes place here through a gas line of a gas extraction device, in this case, for example, in the middle and viewed in the vertical axis direction from top to bottom, in such a way that the support 28 is used as a gas line pipe and is designed with an inlet opening 31 as a gas outlet, which is covered from above by a spaced protective hood 32 against a closure by a gas storage film 24 that has sunk downwards and under which the biogas 27 can flow into the inlet opening 31 (arrows 33). From the upper inlet opening 31 of the support 28, the biogas 27 is guided downwards to the base wall 4 and from there with another gas line 34, for example under the base wall 4, to outside the fermenter area for further use.
- a gas line could also run downwards along it, which could then be conveniently connected to the support 28.
- a drainage device 35 is provided schematically and by way of example outside the fermenter container 1 as a cleaning and/or maintenance device. Condensed water is collected here in a collecting container 36.
- FIG. 2 shows a biogas plant fermenter 1 which largely corresponds to the biogas plant fermenter tank from Figure 1, so that the same parts are designated with the same reference numerals.
- the basic structure and the service device 2 are the same.
- the embodiment according to Figure 2 differs, however, with regard to the gas extraction from the gas storage 25:
- the gas extraction of biogas takes place here in the middle upwards, with a gas line 40 in the form of a bellows 41 with variable length being used above the support area.
- the gas line 40 forms a primary line section here, which here, for example, extends upwards in the vertical axis direction to the highest point or dome tip 44 of the roof outer skin film 20.
- Biogas 27 thus flows from below into the gas line 40, the lower mouth end 37 of which forms the gas outlet, while the upper mouth end of which is here, for example, gas-tightly connected to an opening in the roof outer skin film 20 and from there is passed on with another gas line 42 as a secondary line section for further use.
- the gas line 40 and the gas line 42 can also be formed by a single gas line, which then penetrates the roof outer skin film 20 in the region of the dome tip 44 of the roof outer skin film 20, preferably in a gas-tight manner.
- the gas line 40 or the primary line section can be varied in its length without major restoring forces, since the connection area 43 to the gas storage film 24 changes in its height depending on the filling level of the gas storage 25.
- additional support rings 53 spaced apart from one another can be provided on the bellows 41.
- the gas line 40 preferably has a relatively large diameter.
- Figure 6 shows a further exemplary embodiment in which the platform plate 8 has a mounting wall 46 which projects upwards in the vertical axis direction and extends in the region above the plane of the platform plate 8 and above the upper edge 45 of the container.
- An upper edge region 47 of the mounting wall 46 in the vertical axis direction forms part of the roof connection region 9, to which a partial region of the gas storage film 24 is connected, so that the mounting wall 46 adjoins the gas storage 25.
- the mounting wall 46 here forms the gas outlet 54 opening into the gas storage 25, preferably in such a way that the gas outlet 54 is connected by means of at least one gas line 55 of the gas extraction device, by means of which the gas collected in the gas storage 25 can be extracted from the fermenter container 1.
- an injection device 48 which has a feed pump 49, by means of which injection liquid can be sucked out, here for example from the substrate 7 of the fermenter container 1, as is shown here only schematically by the arrow 50.
- the injection device 48 here further comprises an injection nozzle element 51 which is fluidly connected to the feed pump 49 and by means of which the injection liquid sucked out by means of the feed pump 49 can be injected into the fermenter container 1 in such a way that, with respect to the vertical axis direction, it strikes the surface of a floating layer 52 of the substrate 7 from above as a liquid jet and wets it.
