Abstract
A biogas generating device is disclosed, which aims to efficiently solve two technical problems of severe layered in biogas material and hardness to clear residue and discharge material at the same time. There is one anaerobic fermentor in cylinder shape with two terminals sealed. Air outlet and biological material inlet are opened on one end of anaerobic fermentor housing, and residue outlet is opened on the other terminal of anaerobic fermentor. Rotating shaft gets through the anaerobic fermentor, and mounted on two terminals of anaerobic fermentor by shaft bearings. A helical vane is disposed on rotating shaft inside the anaerobic fermentor, which is driven to rotate by a driving mechanism.
Description
Technical field
The present invention relates to a kind of generating unit of biogas.
Background technology
Biogas is the fuel of a kind of high-quality, efficient, green, environmental protection, and the prospect that substitutes traditional energy is boundless.But, cause sweathouse to have " the poor district of microorganism ", " fermentation blind area " and " feed liquid short circuit " because the methane-generating pit type adopts static fermentation technology.After rural area family expenses hydraulic type biomass pool operation for some time, raw material in the pond progressively is divided into the beds of precipitation, active coating, supernatant liquid and scum layer from bottom to up because proportion is different and the natural subsidence rule in the fermentation container, cause methane-generating pit " crust " problem.Crust has become the outstanding problem that current rural area hydraulic type biomass pool exists.Testing identity for many years is the methane-generating pit of main fermentation raw material with human and animal excreta, and incrustive thickness is 18～25 centimetres after 1 year; With the weeds straw is the methane-generating pit of main fermentation raw material, and crust thickness is 25～35 centimetres after 1 year.Incrustive formation, the biogas that causes in the pond producing are gathered and are obstructed, and useful volume and gas dome reduce, and raw material availability reduces, and gas production rate reduces.Crust when serious, tend to make a methane-generating pit in perfectly good condition to become " sick pond ", useless pond.In addition, methane-generating pit " crust " problem is also brought scarfing cinder discharging difficulty, factor of created gase is low and technical problem such as management inconvenience etc.These problems have had a strong impact on the utilization and the popularization of biogas technology.
In order effectively to solve in the biogas generator technical barrier such as the serious or scarfing cinder discharging difficulty of biogas raw material layering, China's utility model patent " the special-purpose drawing liquid shell breaking pump of methane-generating pit " (patent No. ZL 200520006297.9), designed the special-purpose drawing liquid shell breaking pump of a kind of methane-generating pit, it can be by extracting the natural pond liquid of methane-generating pit, make natural pond liquid enter the methane-generating pit vault and spray downwards, the crust on raw material surface in the methane-generating pit is broken through dissolve along conduit.
Chinese invention patent " full-automatic methane tank " (application number 200510099750.X) belongs to hydraulic type biomass pool, is formed by the water pressure house improvement between discharge room, sedimentation.When sweathouse savings biogas, part natural pond hydraulic pressure toward between discharge room and sedimentation, is produced waterhead, form biogas pressure; When the biogas user used biogas, pressure reduced, and natural pond liquid returns sweathouse.This phenomenon just is permutoid reaction, and it is to come and go mobile that the natural pond liquid that permutoid reaction produces flows.
China's utility model patent " continous way is from deslagging biogas generation tank " (patent No. 200620008635.7) discloses a kind of continous way from deslagging biogas generation tank, and its main body is a cylinder type, and with horizontal oblique installation, obliquity is 1: 3-5; The front bottom end of tank body has opening for feed, and this opening connects feeding-passage, and the rear end of tank body also is at bottom opening, and this opening connects slag releasing channel, and slag bath is inserted out in the upper end of slag releasing channel; Above the biogas jar, be connected to the biogas air outlet; Establishing one at the lower position of feeding-passage in addition is used for connecting provided pipe with the lavatory.
Some has solved the serious technical problem of biogas raw material layering the foregoing invention Patent equipment, some has solved a biogas generator scarfing cinder discharging difficult technologies difficult problem, but, also do not have a kind of device can solve serious and these two technical barriers of scarfing cinder discharging difficulty of biogas raw material layering in the biogas generator simultaneously.
Summary of the invention
The objective of the invention is effectively to solve simultaneously serious and these two technical problems of scarfing cinder discharging difficulty of biogas raw material layering in the biogas generator.
The present invention is a kind of biogas generating device, the anaerobic fermentation tank 1 that the round barrel shape of one two ends sealing is arranged, on the housing of an end of anaerobic fermentation tank 1, have the air outlet 1., the biomass material import 2., on the housing of the other end of anaerobic fermentation tank 1, have slag-drip opening 3., anaerobic fermentation tank 1 is passed in rotating shaft 6, rotating shaft 6 is installed on the housing at anaerobic fermentation tank 1 two ends by bearing 3 respectively, one screw-blade 2 is installed in the rotating shaft 6 that is positioned at anaerobic fermentation tank 1 inside, and rotating shaft 6 is driven by an actuating unit and rotates.
The present invention is the biogas generating device that integrates stirring and deslagging, the effect of the screw-blade 2 in the rotating shaft 6 is equivalent to the effect of a spiral slush pump, screw-blade 2 can stir the biomass material in the anaerobic fermentation tank 1, biomass material in the anaerobic fermentation tank 1 transports from bottom to top, can effectively solve the stratified problem of biogas raw material; When screw-blade 2 rotations, because action of centrifugal force, biological material slag is discharged from anaerobic fermentation tank 1 under the drive of screw-blade 2.
