Along with economy develops the sharply increase with population fast, environmental degradation and energy scarcity become problem demanding prompt solution.With agricultural crop straw, fowl and animal excrement, fruits and vegetables resistates, organic waste etc. for raw material carries out anaerobically fermenting, produce biogas energy, not only solve environmental degradation problem, and generation clean energy realizes China's energy strategy diversification, alleviates the situation of energy availability and demand anxiety.
Anaerobically fermenting is divided into wet fermentation and dry fermentation two class at present.Wet fermentation has obtained permanent development, technology maturation, is widely used in the anaerobically fermenting of lower concentration material, but due to a large amount of water of reaction needed, organism utilization rate is low, can produce a large amount of natural ponds liquid and easily cause secondary pollution after having fermented.And dry fermentation take solid organic castoff as material, do not need a large amount of water in reaction process, the advantages such as adaptability to raw material is wide receive everybody concern.
The problems such as due to the advantage of dry fermentation, recent year expands the research of a large amount of anaerobic dry fermentation technology, and wherein fermentation unit is the emphasis of research and development, solves in dry fermenting process and there is mass-and heat-transfer inequality, the easy acidifying of material, input and output material difficulty
In order to solve these problems, further develop dry fermentation technique, some dry fermentation devices of some Patent designs
Chinese utility model patent " a kind of garage type anaerobic dry fermentation device " (application number: 201020201282.9; Notification number CN201670835U) devise a kind of garage type anaerobic dry fermentation device, this contrive equipment has dry fermentation system and percolate return-flow system; By regularly open leachate tail water reflux carry out sprinkling reach mass-and heat-transfer and contact acid accumulation poisoning and regulation process.This device also has input and output material and facilitates advantage.
Chinese utility model patent " spiral is from stirring dry fermentation device " (application number: 201220365669.7; Notification number CN202705361) devise a kind of spiral from stirring dry fermentation device, material gets off to arrive the high-end of fermentation cylinder from funnel, under the effect of pushing plate, the volution material channel formed along spiral shelf moves down, and roll in fermentation cylinder along spiral septum, realize certainly stirring of material. simultaneouslyIt is little that this device has volume, and factor of created gase is high, and the feature of convenient movement is applicable to the use of plant on a small scale.
Chinese utility model patent " a kind of device being applicable to biological treatment organic garbage of city and agriculture organic waste " (application number: 201420614821.X; Notification number CN204171071U) devise a kind of device being applicable to biological treatment organic garbage of city and agriculture organic waste, comprise garage type dry fermentation device and percolate treatment unit, the dry fermentation stage of described garage type is throw in material in fermentation cabin, airtight, heating and thermal insulation and aeration, after temperature is elevated to anaerobism demand temperature, close aerating system, open sprinkling system, material is inoculated, fermentation, fermentation reaction latter stage, open aerating system, air displacement, open door discharging, fermentation completes.In percolate treating process section, the percolate part produced of fermenting enters a filter spray header by spray pump I, and remainder percolate is delivered to EGSB reactor, and EGSB reacts water outlet and is delivered to vertical shower nozzle by spray pump II.The utility model technique is simple, easy to operate, practical, effectively can solve the environmental problem of organic garbage of city and agriculture organic waste, and comprehensive utilization of resources.
The problems such as above-mentioned patent makes differently to solve mass-and heat-transfer inequality, the easy acidifying of material, input and output material difficulty, but it is high all to there is self energy consumption, complex process, and equipment price is expensive, the high and challenge of running maintenance rate.Do not have a kind of device solving mass-and heat-transfer inequality, the easy acidifying of material, while input and output material difficult problem, implementation structure is simple, and installation cost is low, the feature that energy consumption is low.
Summary of the invention
The object of this invention is to provide a kind of external stirring garage type anaerobic dry fermentation device.
The present invention is external stirring garage type anaerobic dry fermentation device, include garage type fermentation cabin 1, gas-tight door 2, two pieces of incorgruous unidirectional percolate baffle plates 3 are provided with below described garage type fermentation cabin 1, filtering net 4 is provided with above unidirectional percolate baffle plate 3, bottom garage type fermentation cabin 1, two ends are provided with the self balancing telescopic hydraulic cylinder 5 of energy, telescopic hydraulic cylinder 5 is provided with gangs up pipe 6, and gang up in the middle of pipe 6 and be provided with control throttling valve 7, garage type fermentation cabin 1 bottom center is provided with fulcrum 8.
The present invention is compared with background technology, the useful effect had is: adopt garage type structure to facilitate input and output material, garage type fermentation cabin is driven to tilt around fulcrum by self-poise telescopic hydraulic cylinder after charging inoculation, percolate is flowed in fermentation solid, achieve and solve mass-and heat-transfer inequality, the easy acidifying problem of material, shows structure simple assembly cost low, the advantage that energy consumption is low simultaneously.
