Summary of the invention
For overcoming traditional stalk marsh gas pond, difficult sealing, especially input and output material are difficult, stir difficult shortcoming, and the present invention provides a kind of stalk marsh gas fermentation vat.
The object of the invention comes concrete the realization through following technical scheme:
The stalk marsh gas fermentation vat comprises the inner bag that is positioned at outside pond body, is close to pond body inwall installation, at least one Material collecting box for harvesting that is placed in inner bag inside, and said pond body has the outer wall of concrete structure; Said inner bag adopts high molecular synthetic material; Process or be composited like materials such as SE, Vilaterm, rubber, artificial Cowhells linings, said Material collecting box for harvesting adopts plastics, and the inner bottom part of body is provided with several water legs in said pond; Drinking-water pipe is installed in water leg; Inner and upper at said inner bag is equipped with shower, on said shower, is provided with several mouth sprays, is communicated with through the circulated sprinkling pipeline between said drinking-water pipe and the said shower; Above said drinking-water pipe, be provided with the aerodynamic force stirring pipe, the inlet mouth of aerodynamic force stirring pipe passes the pond body, and the aerodynamic force stirring pipe is provided with several air outlets, and the top of body is provided with methane outlet in said pond.
Said circulated sprinkling pipeline is positioned at the outside of pond body, on said circulated sprinkling pipeline, is provided with sludge pump;
Further, on the upstream of said sludge pump, be provided with water-in, on the pipeline of the downstream of said sludge pump, be provided with water outlet;
One side of said pond body is provided with the turnover bin gate, and corresponding said turnover bin gate is provided with the zip mode rolling screen door on inner bag.
The size of said turnover bin gate and said zip mode rolling screen door is greater than the size of each said Material collecting box for harvesting, to allow said Material collecting box for harvesting turnover pond body.
The invention has the beneficial effects as follows: the present invention has overcome traditional stalk marsh gas pond, and difficult sealing, especially input and output material are difficult, stirs difficult shortcoming.Cooperate several groups of methane-generating pits can realize orderly batch aerogenesis, do not need mechanical stirring, practice thrift cost.
Inner bag cooperates the concrete marsh-gas pond of band door, effectively solves the close problem that gets into the people of envelope of methane-generating pit; The Material collecting box for harvesting of plastic material has solved the difficult problem of input and output material; The setting of circulating sprayer has solved the problem that stirs.
