Definitions

  • the invention relates to a transport device for biomass in a fermenter for the generation of biogas, to a large-scale fermenter for the generation of biogas from biomass, and to a method of operating such a large-scale fermenter.
  • Biogas technology has hitherto been mainly concentrated on the “wet fermentation” of liquid manure and biowaste from the municipal sector.
  • Installations and apparatuses for generating biogas from biomass according to the wet fermentation process are known, for example, from publications AT 408230 B, WO 96/12789, DE 3228391 A1, AT 361885 B and DE 19746636 A1.
  • a digester in the form of an elastic tube is known in which digester the biomass is conveyed through the tube by artificially generated peristalsis.
  • the peristaltic motion is generated by means of loops which are drawn over the tube and are pulled tight, by means of sleeves which are drawn over the tube and to which compressed air is applied, or by means of plungers which are distributed over the length of the tube and press successively into the tube.
  • a digester in the form of a round silo is known from DE 19746636 A1, the actual digester being arranged in the center of the round silo and being surrounded by an annular intermediate region.
  • a digester in the form of a round silo is likewise known from AT 361885 B, said digester comprising a cylindrical outer wall and a cylindrical inner wall, as a result of which an annular transport passage is formed.
  • the liquid biomass is fed, flows through the transport passage and is removed again.
  • Vegetable renewable raw materials having a high content of dry substances e.g. corn, grass, whole-plant silage
  • solid manure can only be admixed to a limited extent in the case of these “liquid” methods.
  • “Dry fermentation” allows pourable biomasses from agriculture, from biowaste and cultivated municipal areas to be methanized without converting the materials into a pumpable, liquid substrate. Biomasses having a proportion of up to 50% of dry substances can be fermented. This dry fermentation method is described, for example, in EP 0 934 998.
  • the material to be fermented is not stirred up into a liquid phase, as is the case, for example, with the liquid fermentation of biowastes. Instead, the fermentation substrate introduced into the fermenter is constantly kept moist by the percolate at the fermenter base being drawn off and sprayed again over the biomass. Optimum living conditions for the bacteria are thus achieved.
  • the temperature can be additionally regulated, and it is possible to provide additives for optimizing the process.
  • a bioreactor or a fermenter in the form of a prefabricated garage is known from WO 02/06439, said bioreactor or fermenter being operated according to the principle of dry fermentation by the “batch process”.
  • the fermenter is filled with the fermentation substrate using wheeled loaders.
  • the fermentation container constructed in a garage shape is closed with a gastight door.
  • the biomass is fermented with the exclusion of air; in the process, no further intermixing takes place and no additional material is fed.
  • the percolate seeping from the fermentation material is drawn off via a drainage channel, is stored intermediately in a tank and is sprayed again over the fermentation substrate for the moistening.
  • the fermentation process takes place within the mesophilic temperature range at 34-37° C.; the temperature regulation is effected by means of floor and wall heating.
  • a method and an apparatus for the anaerobic treatment of organic substances having a high proportion of solids, in which biogas is also produced, is known from DE 3341691 A1.
  • the biomass in a channel is subjected to a rolling, peristaltic motion and is thus conveyed through the digester.
  • the peristaltic motion is achieved by the edges of the channel performing an up and down movement parallel to one another.
  • pockets are pressed from below into the channel for producing the rolling motion.
  • the biogas generated can be used in a combined heat and power plant or cogeneration system for generating electricity and heat. So that sufficient biogas is always available for the combined heat and power unit, a plurality of fermentation containers are operated at staggered intervals in the dry fermentation plant. At the end of the dwell time, the fermenter space is completely emptied and then filled again. The fermented substrate is fed for subsequent composting, such that conventional composting of comparable organic manures results. Such a plant has run very successfully in Kunststoff for several years.
  • WO 93/17091 discloses a closed composting apparatus in which compressed air bubbles are arranged in the container base in order to intermix the biomass in the container and in order to transport it through the container from a loading region to a removal region.
  • this transport method is unsuitable for the generation of biogas with the exclusion of air.
  • a transport device for biomass in fermenters is known from WO 2005/085411 A2, in which transport device transport cushions are arranged on the base and on the side walls of the fermenter, which transport cushions can be successively acted upon by a fluid and thus generate a wave motion in order to move the biomass through the fermenter.
  • the transport capacity of such transport cushions is restricted under certain operating conditions of the fermenter.
  • an object of the present invention is therefore to provide a transport device having an improved transport capacity for biomass in a fermenter for generating biogas.
  • the transport device comprises a plurality of transport cushions which are arranged one behind the other in the transport direction and are successively filled with fluid and emptied again.
  • the transport cushions are also additionally arranged and fastened on the base plate of a digester.
  • a wave motion transporting the biomass is generated over the entire width of the transport passage by the up and down motion of the transport cushions.
  • the transport cushions on the base are preferably operated with liquid, in particular with hot water, whereas the transport cushions at 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 deposited between the transport cushions and remaining there.
  • Transport cushions can additionally be assigned to one another in pairs and be arranged opposite one another at the side walls. In this way, too, a peristaltic motion of the biomass through the transport passage is achieved or assisted.
  • 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-scale fermenters as claimed in claim 7 are thereby provided.
  • fresh biomass in a loading region is introduced via a transfer lock into the large-scale fermenter constantly producing biogas.
  • the biomass is transported from the loading region to an unloading region by the transport device.
  • biogas is generated and the biomass is “spent”.
  • the unloading region the “spent” biomass is removed via a transfer lock.
  • continuous operation is also possible during the generation of biogas according to the principle of the methanization of solids.
  • round containers which have fewer corners and edges with leakage problems, are therefore known from the sector of wet fermentation, in which the liquefied biomass can be pumped into and out of the digester.
  • these round containers are not used on account of the problems during loading and unloading in batch operation. Due to the transport device according to the present invention and the continuous operation possible with said transport device, round containers can also be advantageously used in the case of “dry fermentation”—claim 9 .
  • the design having an inner wall in the form of a circular ring and an outer wall in the form of a circular ring and surrounding the inner wall results in an annular fermenter container with an annular transport passage.
  • This circular-ring cylinder is subdivided by a dividing wall.
  • the biomass is continuously fed in a loading region on one side of the dividing wall and is continuously discharged in an unloading region on the other side of the dividing wall at the end of the transport passage.
  • the feeding of the fresh biomass in the loading region and the removal of the spent biomass in the unloading region are effected via transfer locks, for example through a liquid bath like a siphon.
  • a thrust cushion is provided in the region of the loading device in addition to the bottom, top and/or lateral transport cushions, and this thrust cushion can expand in the transport direction and thus additionally presses the biomass in the transport direction—claims 8 and 11 .
  • the percolate extracted from the half-fermented biomass is filtered and the filtrate produced is fed again to the digester together with the microorganisms concentrated therein. This improves the biogas production.
  • FIG. 1 shows a schematic illustration of an elongated large-scale fermenter, the base of which is covered with transport cushions;

  • the large-scale fermenter 2 comprises, at one end, a loading region 10 having a loading device 12 (indicated by an arrow) passing through the end wall 8 and, at the other end, an unloading region 14 having an unloading device 16 (likewise designated by an arrow) passing through the rear wall 9 .
  • a transport passage 18 defined by the two side walls 6 and 7 is formed between loading region 10 and unloading region 14 .

That is to say, the top side of the transport cushions is arched and does not appear so straight as in the illustrations in FIGS. 1 to 6 .
  • the expansion of the individual transport cushions 24 - i upward can be periodically increased and reduced by periodic feeding and removal of fluid by means of a fluid control device 26 .
  • a wave motion can be generated by the feeding of fluid to and removal of fluid from directly adjacent transport cushions 24 - i , the biomass 22 being conveyed from the loading region 12 to the unloading region 14 by said wave motion.
  • FIG. 2 shows a plan view of the front part of the transport passage 18 of the large-scale fermenter according to FIG. 1 .
  • a thrust cushion 25 which presses biomass in the transport direction by fluid being applied to it repeatedly, is arranged on the end wall 8 .
  • a plurality of thrush cushions 25 arranged one above the other may also be provided.
  • FIGS. 3 a , 3 b and 3 c The continuous transport of biomass 22 by the transport cushions 24 - i is shown schematically in FIGS. 3 a , 3 b and 3 c for a large-scale fermenter 2 filled with biomass 22 .
  • FIGS. 3 a , 3 b and 3 c each show ten transport cushions 24 - 1 to 24 - 10 distributed over the transport passage 18 .
  • No transport cushion is provided in the unloading region 14 .
  • fluid is pumped into the last transport cushion 24 - 10 upstream of the unloading region 14 against the weight of the biomass 22 carried on the last transport cushion 24 - 10 , and the biomass 22 carried on the last transport cushion 24 - 10 is lifted and falls partly into the free unloading region 14 .
  • the fluid is removed from or pumped out of the last transport cushion 24 - 10 .
  • fluid is pumped simultaneously into the penultimate transport cushion 24 - 9 .
  • the transport cushion 24 - 8 is thereupon inflated while the transport cushion 24 - 9 is emptied— FIG. 3 c —until finally the first transport cushion 24 - 1 is inflated and emptied again (not shown).

  • This generates a wave motion, which continuously conveys the biomass 22 from the loading region 10 to the unloading region 14 .
