Definitions

  • the invention relates to a transport device for biomass in a fermenter for producing biogas according to claim 1, a large fermenter for producing biogas from biomass according to claim 7 and a method for operating such a large fermenter according to claim 11.
  • biogas technology has mainly focused on the "wet gasification" of manure and / or bio-waste from the municipal sector.
  • Plants and devices for generating biogas from biomass using the wet fermentation process are e.g. B from publications AT 408230 B 1 WO 96/12789, DE 3228391 A1, AT 361885 B and DE 19746636 A1.
  • DE 3228391 A1 discloses a digester in the form of an elastic hose in which the biomass is conveyed through the hose by means of an artificially generated peristalsis.
  • the peristaltic movement is generated by means of loops which are pulled over the tube and which are drawn together, by means of cuffs which are drawn over the tube and are pressurized with compressed air or by means of stamps distributed over the length of the tube which successively press into the tube.
  • digester in the form of a round silo is known, the actual digester being arranged in the center of the round silo and surrounded by an annular intermediate area.
  • AT 361885 B also discloses a digester in the form of a round silo, which has a cylindrical outer wall and a cylindrical one
  • the liquefied biomass is fed in, flows through the transport and is removed again.
  • AT 361885 B it is known from AT 361885 B to provide a cylindrical middle wall between the inner and the outer wall, as a result of which an inner and an outer transport channel ring are formed.
  • Renewable raw materials with high dry matter contents e.g.
  • Corn, grass, whole plant silage) or solid manure can only be added to a limited extent in these "liquid” processes.
  • dry fermentation makes it possible to methanate pourable biomass from agriculture, from organic waste and municipal care areas without converting the materials into a pumpable, liquid substrate.
  • Biomass with up to 50% dry matter can be fermented. This dry fermentation process is described, for example, in EP 0 934 998.
  • the material to be fermented is not stirred into a liquid phase, as is the case, for example, with the liquid fermentation of bio-waste. Instead, the fermentation substrate introduced into the fermenter is kept constantly moist by pulling the percolate off the bottom of the fermenter and spraying it again over the biomass. In this way, optimal living conditions for the bacteria are achieved.
  • the temperature can also be regulated, and there is the possibility of adding additives for process optimization.
  • a bioreactor or a fermenter in the form of a prefabricated garage is known from WO 02/06439, which is operated according to the principle of dry fermentation in the so-called batch process.
  • the fermentation substrate is filled with wheel loaders in the fermenter.
  • the fermentation tank which is built like a garage, is closed with a gas-tight gate.
  • the biomass is fermented in the absence of air, there is no further mixing and no additional material is added.
  • the percolate seeping out of the fermentation material is drawn off via a drainage channel, temporarily stored in a tank and sprayed again over the fermentation substrate for moistening.
  • the fermentation process takes place in the mesophilic temperature range at 34-37 0 C, the temperature is controlled by means of floor and wall heating.
  • DE 3341691 A1 also discloses a method and a device for the anerobic treatment of organic substances with a high solids content, in which biogas is also produced.
  • the biomass is subjected to a peristaltic movement that moves and is thus conveyed through the digester.
  • the peristaltic movement is achieved in that the edges of the channel execute an up and down movement parallel to one another.
  • pockets are pressed into the channel to generate the walking movement.
  • the resulting biogas can be used in a combined heat and power plant to generate electricity and heat.
  • several fermentation tanks are operated at different times in the dry fermentation plant.
  • the fermenter room is completely emptied and then refilled.
  • the fermented substrate is fed to post-composting, so that a conventional compost of comparable organic fertilizers is created.
  • Such a system has been running successfully in Kunststoff for several years.
  • Known large fermenters generally work in batch mode, i.e. the fermenter biogas production must be interrupted for loading and unloading and the fermenter filled with biogas must be flooded with air.
  • Loading area is transported to an unloading area.
  • a closed composting device is known from WO 93/17091, in which bubbles can be acted upon by compressed air in the bottom of the container - A -
  • a transport device for biomass in fermenters is known from WO 2005/085411 A2, in which transport cushions are arranged on the bottom and on the side walls of the fermenter, which can be acted upon by a fluid in succession and thus generate a wave movement around the biomass through the fermenter to move. Under certain operating conditions of the fermenter, the transport performance of such transport cushions is restricted.
  • the transport device comprises a plurality of transport cushions arranged one behind the other in the transport direction, which are successively filled with fluid and emptied again.
  • the transport cushions are additionally arranged and fastened on the base plate of the digester. The up and down movement of the transport cushions creates a wave movement that transports the biomass across the entire width of the transport channel.
  • the transport cushions on the floor are preferably operated with liquid, in particular with warm water, while the transport cushions on the cover are preferably operated with a gas which does not form an explosive mixture with the biogas.
  • a transport cushion cover prevents biomass from being stored between the transport cushions and remaining there.
  • transport cushions can also be assigned to one another in pairs and arranged opposite one another on the side walls. This also achieves or supports a peristaltic movement of the biomass through the transport channel.
  • the transport device according to the present invention can be installed in conventional bioreactors or fermenters, as are known for example from WO 02/06439 A or WO 2005/085411 A2.
  • large fermenters according to the invention are provided according to claim 7.
  • fresh biomass is introduced in a loading area via a lock into the large fermenter which constantly produces biogas.
  • the biomass is transported from the loading area to an unloading area by the transport device.
  • biogas is generated and the biomass is "used up".
  • the unloading area the "used” biomass is removed via a lock. This also means that continuous operation is possible using the principle of solid methanation.
  • round containers are therefore known which have fewer corners and edges with sealing problems. These round tanks are not used in solid methanation in large fermenters due to the problems with loading and unloading in batch mode. Due to the transport device according to the present invention and the continuous operation that this enables, round containers can also advantageously be used in “dry fermentation” - claim 9.
  • the round design of the large fermenter significantly reduces sealing problems, since the outer wall and the inner wall are only subjected to pressure or tension. The usual tightness problems of corners and edges are avoided.
  • the construction with an annular inner wall and an annular outer wall surrounding the inner wall results in an annular fermenter container with an annular transport channel.
  • This circular cylinder is divided by a partition.

  • a push cushion is provided in the area of the loading device, which can be expanded in the transport direction and thus also pushes the biomass in the transport direction - claims 8 and 11.
  • Another object of the present invention is to provide a method for operating a large fermenter according to the present invention.
  • the high liquid content of the biomass can lead to excessive liquefaction of the biomass in the digester. This would lead to a severe impairment of the transport effect of the transport device with transport pillows.
