Abstract
The invention relates to an obstructing-net type anaerobic reaction three-dimensional fluidized bed. The obstructing-net type anaerobic three-dimensional fluidized bed, called as an anaerobic fluidized bed for short thereafter, is such structured that the interior of a heat preservation glass fiber reinforced plastic anaerobic tower is separated into a plurality of layers by nylon nets (1) and multi-faceted foam hollow balls (2) and interior-and-exterior double-layer balls are put among the separated layers according to different specifications and proportions so as to form a three-dimensional structure. The working process of the anaerobic fluidized bed is as follows: 1, a multi-faceted foam hollow ball biogas fertilizer is injected, wherein a biogas fertilizer is filled with the multi-faceted foam hollow balls, the balls are located at the middle-upper part of the separated nets due to buoyancy, and anaerobic bacteria are fully fused under stirring and heating effects; 2, an interior-and-exterior double-layer ball biogas fertilizer is injected, wherein the interior-and-exterior double-layer balls are fully distributed in a biogas fertilizer and located at the middle-lower part of the separated nets, and anaerobic bacteria are fully fused under stirring and heating effects. The anaerobic fluidized bed provided by the invention has a maximum high-efficiency three-dimensional anaerobic flora fusion surface and is an ideal apparatus for the industry of biomass natural gas.
Description
Technical field
Floatingization of anaerobism bed relates to the inner structure that forms of a kind of methane digestion tank.
Background technology
In existing biogas anaerobic fermentation pond.There is perfectly mixed reactor (CSTR); Plug flow type inductor block (PFR); Flow lifting type Sludge Bed (UASB); Flow lifting type solid inductor block (USR); Internal recycle inductor block (IC); Anaerobic filter (AF); Anaerobic fluidized bed, expanded bed (AFBR) etc.Its complex structure, equipment is used many, and cost is high, technological operation is difficult to be controlled, for the current biogas growth requirement of China, exist certain poor certificate, and floatingization of anaerobism bed is on heat insulation glass anaerobic tower (201210225454.X) basis, use new technology, novel method, meet biomass Gas Industry demand for development, be applicable to again the realistic situation of China's national situation.Whatsoever local, can realize the development of efficient biomass Gas Industry.
Summary of the invention
Order of the present invention is to adopt a kind of brand-new biogas anaerobic fermentation device internal structure.Impel anaerobic bacteria flora and complete mixed organism fully to merge.In high temperature, middle temperature (65-30 ℃) temperature of reaction environment, obtain high yield biogas, for achieving the above object.
The invention provides a kind of floatingization of anaerobism bed.
Floatingization of anaerobism bed, is arranged on heat preserving fiberglass anaerobic tower inwall, and multilayer intercepts net.
Floatingization of anaerobism bed, is arranged on heat preserving fiberglass anaerobic tower inwall, and multilayer intercepts in net, every layer of configuration certain volume, some amount, ball-type multiaspect porous plastics hollow ball, inside and outside double-layer polyethylene material and plastics pompon.
Floatingization of anaerobism bed, intercepts net in multilayer, configuration certain volume, and quantity ball-shaped filling material combines three-dimensional arrangement.
Specific implementation method
Floatingization of anaerobism bed of the present invention, at heat preserving fiberglass anaerobic tower interior wall construction as shown in Figure 1.
1, floatingization of anaerobism bed of the present invention, is fixed some annular go-no-go nylon wires with unsaturated polyester by heat preserving fiberglass anaerobic tower inwall.Form multilayer and intercept net (1).
2, floatingization of anaerobism bed of the present invention, each layer of configuration some amount multiaspect porous plastics hollow ball (2).
3, floatingization of anaerobism bed of the present invention, double-layer polyethylene and plastics pompon (3) inside and outside each layer of configuration some amount.
Fig. 2 is in heat preserving fiberglass anaerobic tower, single layer structure schematic diagram, with unsaturated polyester fixedly nylon plastic intercept net (1), between resistance net, some multiaspect porous plastics hollow balls (2) are set, some inside and outside double-layer polyethylenes and plastics pompon (3) are set between resistance net.
Each level by upper or under, copy successively single layer structure, until resistance net formula anaerobism cubic floating bed completes.
Fig. 3 is multiaspect porous plastics hollow ball schematic diagram, and injection moulding middle part girth has a reinforcing ring, and ring upper and lower part respectively has some balls to distinguish.In edge, from axle, be radiation and arrange, form multiaspect porous plastics hollow ball (2).
Fig. 4 is inside and outside double-layer polyethylene and plastic wire spheroid schematic diagram.Injection molded polyethylene material outside is hollow fish netted spheroid, and inner plastic wrapping constitutes inside and outside double-layer polyethylene and plastic wire spheroid (3).
Finally should illustrate, above enforcement anaerobism cubic floating bed process, is to produce special-purpose anaerobism equipment for realizing biomass Sweet natural gas completely, makes by tradition small-sized anaerobism equipment and external anaerobism utensil.Realize the autonomous biomass Sweet natural gas of China, production unit.At the bottom of manufacturing cost, be suitable for China's wide geographic area and prior art level.
Claims (4)
1. hinder net formula anaerobism cubic floating bed, its global feature is, is provided with some layers of go-no-gos and intercepts nets in heat preserving fiberglass anaerobic tower, between resistance net, configures certain proportion, several spheroid.
