Definitions
- the invention relates to the production of biogas by multi-stage fermentation in a mono container.
- Biogas plants in view of increased raw material prices and in the context of enforceable conditions with regard to plant safety and environmental compatibility.
- biogas plants consist of one or more insulated and heated fermenter tanks, in which by wet fermentation process for the generation of biogas from suitable substrates organic dry matter is implemented by microbial methanogens.
- the fermenters are more containers or lagoons for
- Gas storage container or they are formed on one or more roofs of the aforementioned container. Otherwise, all containers are covered gas-tight.
- the individual containers are provided with stirrers or other options of mixing.
- the Feeding or treatment, collection or removal of digestate, gas, condensate, water and electricity requires various piping systems, pumps, fittings, etc., which will allow the individual components to become a complex constituting a functioning biogas plant. Furthermore, measuring, control, and control devices are essential for this.
- the method described with the publication DE 10 2007 029 700 includes a
- Biomass power plant comprising a plurality of fermenters of the garage type, but also expressly not for wet, but for dry fermentation.
- Gas is removed without first collecting the gas in a flexible diaphragm accumulator.
- the fluid is discharged without the sections can be filled or emptied independently.
- the writings mentioned also include no gas spaces, which are independent of the sections in individual or collective gas storage, which are connected directly to the container wall, designed as a gas membrane memory.
- the invention has for its object to further simplify the technical conditions in containers for the fermentation processes and to limit the number of containers to be used for each specific process steps to a mono container.
- the effort has been reduced to a necessary minimum to make the multi-stage operation of biogas plants more cost-effective and, moreover, to make the ongoing operation economically more effective.
- Various stages of fermentation are concentrated according to the invention and take place in a single container. Process steps such as hydrolysis, fermentation to acetic acid, C0 2 and H 2 , fermentation to methane are separated. Due to the multiple stages of fermentation, there is a high material utilization of the feeds. There is an optimization of the fermentation conditions in spatially separated container segments. Depending on the reaction progress, the residence time in the respective
- the container body as shown in Figure 1 consisting of the bottom (1), at its edge immediately adjacent or on this, the upright and self-contained container outer wall (2), also formed cylindrical with a vertical cylinder axis, inside provided with additional separations (3), with their arrangement, the total volume of the container body can be divided variably into at least two or more sub-volumes.
- additional separations are not standalone containers nor are they made of such.
- the container sectors are self-contained
- the height of the inner partitions is usually identical to that of the outer wall, but may also be smaller or vary with each other. Like the other parts of the mono container, they can be made of concrete, metal, stainless steel, plastic or composites, but they do not have to be identical in composition or in terms of material. The prerequisite is that the seams between the inner walls and with the outer wall are liquid-tight. The outer wall is insulated against heat loss.
- the container body is provided via individual reaction chambers according to the prior art variable with a solid or membrane-like cover (4-6), which may be gas-tight or odor-inhibiting.
- Biogas plants the investment costs for the construction by 30 to 40 percent lower. Due to a reduction of soil sealants, better compatibility with nature and landscape and due to smaller area requirements, the monobloc container can show further positive aspects compared to a multi-tank biogas plant.
- Tank section independent levels, reaction liquids, temperatures and flow rates can be realized.
- the biogas plant can optionally be used for the fermentation of only one substrate (mono-fermentation) or a substrate mixture.
- the substrate is fed prior to introduction into the mono container by means of screw systems or other suitable conveyors in the mono container, or optionally homogenized by means of technical devices and added by adding liquid in a pumpable state and further fed to the mono container.
- Organisms that are unable to directly absorb the macromolecules of carbohydrates, proteins and fats, for example, the polysaccharides of starch to oligo- and monosaccharides, proteins to peptides and amino acids, fats in glycerol and fatty acids hydrolyzed. If required and advantageous, several hydrolysis spaces can also be designed which accommodate different inputs with variable temperature and residence time.
- the substrate provided with the products of the hydrolysis reaches the next stage of the fermentation, the actual fermentation, for what in the
- Mono efforter structurally one chamber (8) or more container sectors (8, 9) of the same or differentiated volume can be provided.
- acidification takes place via various compounds, at the end of which acetic acid predominates.
- This is the basis for metabolic processes of certain strains from the group of archaea, in the result of which, in addition to other products, methane is also formed as a constituent of biogas, which accumulates in the gas store.
- Fermentation rooms either with a common or with individual heaters (10) on or in the ground or on or in the outer walls equipped.
- the fermenter residence time of the substrate and the associated space load vary depending on the composition of the substrate. It is desirable that as much as possible of the organic dry matter available to the metabolism be converted within the shortest possible time in the biogas production process. This is not linear, and the yield drops sharply towards the end of the process.
- the remaining digestate arrives at the appropriate point in time in one or more Gärrestlagersektoren (11) of the monobody. Because the emptying usually seasonal discontinuous, it will have different levels (12) as well as the levels in the other container segments can be quite differentiated. In individual cases, the digestate storage can also be arranged externally or supplemented by such.
- Substrate components e.g. cellulosic, causes, which otherwise escaped as a result of the too short residence time in the fermenter of a Verstoff Playung as far as possible.
- a higher gas yield is achieved.
- the required mass transfer or exchange toward the, between and from the individual reaction chambers is realized by means of pumping systems (13) over the shortest precipitating bushings and connections.
- Different levels in the individual container sectors are achieved independently of pumping operations by weir-type variably adjustable or fixed overflows (16), if they are container sectors with the same gas pressure.
- the formation of optimal environments in the reaction chambers can be controlled by agitators (14) and the targeted triggering of intermixing and
- Multifunctional access shafts allow access to the fermenter compartments during inspections, repair or cleaning, or for the introduction or removal of aggregates and devices.
- Short transport and pumping paths generate lower design requirements with respect to the required aggregates, reduced operating times, minimize the electrical power consumption and the current demand of the biogas plant.
- an ultrasound module is integrated into the treatment and hydrolysis system for further optimization of the substance digestion.
- This ultrasound module is in the simultaneously filed German patent application with the file number
- a multi-stage self-regulating ultrasonic disintegration system is provided, which is not installed between or not externally in a separate container, but compactly combines the necessary components and required elements in a system for direct attachment or installation to the mono container, without a to require separate building or container placement.
- the ultrasound module comprises the following elements:
- the ultrasound module promotes the medium to be disintegrated from the
- Mono about pipe-like elements with an integrated conveyor. It is mounted on or in the mono container. The liquid is via shut-off devices
- Piping elements, flow measuring devices and devices for receiving sensors and transducers and the conveyor in preferably vertical flow centric promoted in the pipes sonotrodes.
- the sonotrodes are coupled with matching reflectors, which are located at a suitable distance parallel to the probe centric in the media stream.
- the system is designed so that the medium to be disintegrated from the
- Mono container is promoted to the disintegration probes.
- the flow is one or more stages. Between the stages of disintegration, the effects of the individual can be achieved via integrated measuring sockets and sensors
- Disintegration nozzle are determined. These may be the viscosity and or the Temperature, electrical power consumption of the sonotrodes and the conveyor can be measured. Depending on the measurement or evaluation results, the system may activate further stages via the conveyor (preferably a pump), thereby making it possible to increase the intensity (lower flow rate), reduce the intensity or cause backwashing.
- the frequency and the number of sonotrodes can be adapted to the amount and intensity of disintegration.
- the integrated conveyor or devices may perform an opposite direction of flow, e.g. backflushings
- the conveyor may adapt the capacity to the needs / requirements (e.g., speed control).
- the system is capable of being controlled by a system controller based on
- Volume measuring device and the communication with a possibly existing subordinate control or the own control the effects and the function increase.
- this ultrasound module is able to measure the effect of the sound directly through the integrated control, the intensity through
- volume flow control and or change the flow direction (different passage of the liquid to be treated over different number of sonotrodes) and adapt to the needs.
- the self-cleaning of the system is by reversing or changing the flow direction and the possibility of increasing the volume flow as the
- the system is with all commercially available sonotrodes for Inrohr- or
- Anrohrinstallation (ie both sonotrodes integrated directly in the flow of liquid to be treated as well as on the pipe outer wall or in the pipe outer wall) can be equipped.
- the waveform according to the invention of the pipe guide of the ultrasound system on the one hand serves to optimize the hydraulic system and on the other hand ensures the achievement of a compact design taking into account the space required for all components to be integrated.
- the system can different number of sonotrodes or
- the system can be installed on or in the mono container, also as a bypass system or as an inline system.
- the advantages of the combination of the monobody with the ultrasound module according to the invention are u.a. in that the investment costs for an ultrasound module are reduced by about 50% compared to currently about costs of about 200T €. In addition, this system also significantly reduces operating costs, since the direct connection to the mono container can reduce the conveying paths many times and can also be installed in a streamlined and clog-proof manner.
- the ultrasound module needs no building-like enclosure, but it is sufficient for piping installations usual measures for insulation and weather protection.
- FIG. 4 shows a side view of the ultrasound module.
- the ultrasound module is attached to the outside of the container inner wall.
- FIG. 2 shows a plan view of the ultrasound module. It can be seen that the ultrasound treatment takes place directly in the substrate line - so no extra container is necessary - and the sonotrodes are either in or outside the substrate lines. Also visible are the measuring and flushing nozzles and the valves (pipe shut-off elements) as well as the pump (conveyor).
- Ultrasonic treatment can be switched on.
- the waveform of the ultrasound module according to the invention is particularly clearly shown in FIG. Reference list for the mono container
