Definitions

  • 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

  • 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.

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.

  • 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.
