Background technology
At present, the energy and environmental pollution have become the fast development of restriction Chinese national economy and the bottleneck problem that improves constantly of living standards of the people, and in the moment of this sternness, the task of top priority is to expand variety of energy sources, enlarges the use of the renewable energy resources.Biogas has long utilization history as regenerated, cheap clean energy in China; the building time of methane-generating pit is short, cost is low, technology maturation is reliable; therefore carry out the use of methane-generating pit construction, universal biogas on a large scale and be not only one of good method that solves China's energy dilemma; but also be one of good approach that solves agricultural environment pollution, tally with the national condition very much.
Marsh gas fermentation pool during the fermentation, fermentation raw material can be divided into and contain the profuse sediment layer of zymophyte, contain abundant few clear water layer and the few scum layer of zymophyte of active coating, zymophyte of zymophyte from bottom to up.During the fermentation, substratum (fermentation raw material just) will fully engage with zymophyte just can reach the purpose that fermentation fully improves gas production rate, to often fully broken shell stirring of methane-generating pit, on the basis of equal fermentation raw material, can improve gas production rate more than 30%, not only biogas energy can be increased in plant, but also the speed of handling agricultural pollution can be improved.At present, the methane-generating pit broken shell is stirred many kinds of methods, but the ubiquity complex operation, time-consumingly take a lot of work, problem such as efficient is low, and all can not reach the purpose that abundant broken shell is stirred in practice.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of simple in structure, convenient, low cost of manufacture of installation, marsh gas fermentation pool can be reached fully thoroughly stir purpose methane-generating pit bottom natural pond liquid supercharging backflow broken shell whipping appts.
The technical solution of the utility model is achieved in that a kind of methane-generating pit bottom natural pond liquid supercharging backflow broken shell whipping appts, comprise fermentation vat, feed-pipe and water pressure house, described feed-pipe one end is communicated with fermentation vat, described water pressure house is positioned at fermentation vat one side and is communicated with it, it is characterized in that: be provided with the natural pond liquid distributor at described fermentation vat inner top, described natural pond liquid distributor is communicated with by being provided with the curved pipeline of the heavy water taps outer with being arranged on fermentation vat, in described water pressure house, the discharge port place of fermentation vat is provided with the submersible pump that is communicated with described taps by pipeline.
Methane-generating pit bottom described in the utility model natural pond liquid supercharging backflow broken shell whipping appts, its described submersible pump is arranged in the strumbox.
Methane-generating pit bottom described in the utility model natural pond liquid supercharging backflow broken shell whipping appts, its described natural pond liquid distributor is made up of the natural pond liquid faucet that several are evenly distributed on the fermentation vat inner top, and described natural pond liquid faucet is communicated with pipeline by corresponding arm respectively.
The utility model is provided with submersible pump by discharge port place in fermentation vat, the fermentation vat bottom can be contained the abundant natural pond liquid of zymophyte and extract the scum layer that is circulated into fermentation vat again by the natural pond liquid distributor backflow uniformly that is arranged on the fermentation vat inner top out, rely on submersible pump to take out under the acting in conjunction of the continuous pressure that reduces of the pressure of natural pond liquid, the downward pressure of natural pond liquid self and fermentation vat bottom natural pond liquid in addition, make marsh gas fermentation pool can reach the purpose that fully thoroughly stirs.The utlity model has that simple in structure, low cost of manufacture, installation are convenient, sufficient advantage is stirred in broken shell.
