In recent years, carried out the research and development of a large amount of anaerobic dry fermentation technology both at home and abroad, wherein fermentation unit is the emphasis of research and development, and vertical tank type and garage type are two kinds of type of device that current anaerobic dry fermentation technology adopts usually.Vertical tank type structure generally adopts the continuous feeding and discharging operation, and technology is too complicated, and equipment price is expensive, and the running maintenance rate is high and complicated, applies difficulty.Garage type structure generally adopts intermittent type input and output material operation in batches, also can carry out continuous biogas fermentation production through several same garage type fermentation unit is set.From present whole research and development level and development prospect, garage type dry fermentation device will become the developing direction of the tool prospect in anaerobic dry fermentation field.But garage type dry fermentation device also exists construction cost high at present, the sealing difficulty, and the mass-and heat-transfer weak effect, acid accumulation is poisoned easily, and fermenting process is easy-regulating not, problems such as input and output material difficulty.
Based on above-mentioned situation, the application provides a kind of software garage type anaerobic dry fermentation device, and it is high that emphasis solves garage type anaerobic dry fermentation construction cost, sealing difficulty, mass-and heat-transfer weak effect, problems such as input and output material difficulty.
Summary of the invention
The utility model technical problem to be solved is: high to the existing garage existing construction cost of type anaerobic dry fermentation device, and the sealing difficulty, the mass-and heat-transfer weak effect, acid accumulation is poisoned easily, and fermenting process is easy-regulating not, problems such as input and output material difficulty.A kind of novel software garage type anaerobic dry fermentation device is provided; This plant construction is simple, cost is low and the sealing easy; Input and output material efficiently and easily; The measure that can also add through digestion percolate pump around circuit and bacterial classification solves mass-and heat-transfer weak effect, acid accumulation poisoning and fermenting process problem such as easy-regulating not easily.
The technical scheme of the utility model is achieved in that a kind of software garage type anaerobic dry fermentation apparatus main body is made up of software garage type fermentation system and percolate pump around circuit system.Software garage type fermentation system comprises garage type fermentation cabin, software sealing membrane, methane outlet, percolate spray header and leachate collection system; The software sealing membrane is installed in type fermentation cabin side, garage and end face open-mouth; Adopt inflatable flexible pipe-C type groove sealing between software sealing membrane and garage type fermentation cabin body of wall; Methane outlet is located at the top of software sealing membrane, and the percolate spray header is located at the top of garage type fermentation cabin, and leachate collection system is located at the bottom of garage formula fermentation cabin; The percolate circulation reflux device comprises leachate collection jar and the water pump that is provided with liquid pumping hole and fluid inlet and inoculation mouth; Fluid inlet is located at the bottom of leachate collection jar; Liquid pumping hole and inoculation mouth are located at the middle and lower part of leachate collection jar respectively, and water pump is contained between liquid pumping hole and the spray header.Spray header in the garage type fermentation cabin is connected with the water pump of percolate reflux through pipeline, and the filtrate collection system of garage type fermentation cabin is connected with the fluid inlet that is located at the leachate collection pot bottom.During the device operation, open a side software sealing membrane, carry out the batch charging, after the completion of waiting to feed, the sealing of inflatable flexible pipe, the charging stage accomplishes; Get into fermentation stage, open the percolate circulation reflux device, realize evenly inoculating, after fermentation is normal, regularly opens the percolate circulation reflux device and carry out the percolate spray cycle, reach the purpose that efficient mass transfer conducts heat and removes acid accumulation poisoning and regulation and control fermenting process.
In order to control the leavening temperature in the garage type fermentation cabin, in garage type fermentation cabin body of wall, heating tube and thermal insulation layer are housed, at the different positions of body of wall TP is housed.
In order to control the percolate temperature in the percolate circulation reflux device, at leachate collection jar inner bottom part heating system is housed, in the tank body middle and lower part TP is housed.
