Abstract
The utility model discloses a device for eliminating biogas digester scum, comprising a conveying pump and a transmission pipe. The utility model is characterized in that a liquid storage groove is arranged above a biogas digester; the input port of the conveying pump is arranged at the bottom of the biogas digester and the output port of the conveying pump is connected with the liquid storage groove; a water-sealing groove and a liquid dumper are arranged above the biogas digester, the outlet pipe of the liquid storage groove is communicated into the water-sealing groove while a nozzle of the outlet pipe is below the liquid surface; the water-sealing groove is provided with an overflowing mouth which enables the liquid to flow into the liquid dumper; an active cover is arranged above the water-sealing groove. The utility model solves the incrustation problem of the biogas digester scums and also the biogas is not easy to be leaked out with safety and reliability. Compared with the biogas digester without the device, the biogas production can be increased more than 50 percent, while the utilization ratio of the fermenting materials can also be improved with the wide use of the straw fermenting material.
Description
Technical field
The utility model relates to a kind of device of eliminating scum silica frost in the methane-generating pit.
Background technology
Along with development of rural economy and national requirements protection to natural, ecological; construction methane generating pit more and more becomes the active demand of peasant household; utilizing domestic birds and animals ight soil and agricultural waste material to be put into methane-generating pit ferments; can obtain the high-quality farm manure on the one hand; can produce clean energy on the other hand, be accepted by vast farmers.But it is the fermentation of compound state type that peasant household builds the biogas fermentation of methane-generating pit, natural pond bacterium self-reproduction can produce biogas in the fen, gas form with small bubbles in water rises, bubble is because surface tension effects can be attached to fermentation material surface, and it is floated to liquid level, these buoyants rest on the liquid level of fermentation vat inside, can form the not only thick but also tough scum silica frost of one deck after gathering for some time.These scum silica frost not only can not arranged from upflow tube, even safety tube also is difficult to discharge, cause virgin material to advance not go, old material can not overflow, also can make during charging in the pond and to form very big pressure and push away removable cover, the caking of scum silica frost also causes the scum silica frost crust on top to form " dead band ", and scum silica frost forms a large amount of cellulosic materials can not thoroughly be decomposed, and biogas can not rise to gas tank, natural pond bacterium breeding of a specified duration is slowed down, even dead, cause not aerogenesis, thereby crust back gas production factor is little, the dry-matter residual quantity is big, have the pond raw material of going into of 1/2-2/3 to fail effectively to be decomposed approximately, raw material availability only is 40%-50%, and its actual turnover ratio only is about 1/2 of a theoretical value.At these scum silica frost, the method for people's processing at present has multiple, and the one, adopt mechanical stirring, scum silica frost is scratched openning; The 2nd, add pharmaceutical chemicals, allow natural pond slag accelerate decomposition under chemical action; The 3rd, adopt forms such as pressing scaffold, center cage that the natural pond slag is dipped in the liquid of natural pond.But there are many weak points in above-mentioned method, and mechanical stirring power is bigger, and timeliness is not long, also needs to open removable cover and drags for scum silica frost and stop air feed; Add pharmaceutical chemicals and can not spread on the scum silica frost, increased peasant's additional expense again; Press members such as scaffold, center cage to damage easily.In recent years, domestic some new hulling machines that begun one's study, but effect is unsatisfactory, and the fen that causes that has leaks gas.The operation that has is comparatively complicated, is not suitable for the little methane-generating pit of peasant household.
Technology contents
For the scum silica frost crust problem of the little methane-generating pit that solves present peasant household, the inventor is through overtesting and research, designed a kind of simple in structurely, easy to operate, and treatment effect is good, the device of scum silica frost in the elimination methane-generating pit that biogas does not leak.
The technical solution of the utility model is achieved in that
The device of eliminating the methane-generating pit scum silica frost comprises transferpump, transport pipe, is characterized in: have reservoir above outside exceeding fen, the input aperture of transferpump is in the methane-generating pit bottom, the output of transferpump inserts in the reservoir, water sealed tank and natural pond liquid tipping bucket carriage are installed above in methane-generating pit, the reservoir outlet pipe leads in the water sealed tank, and the mouth of pipe is immersed under the liquid level; Water sealed tank has overflow port, and natural pond liquid is flow in the liquid tipping bucket of natural pond, and there is removable cover the water sealed tank top, and removable cover is embedded with conduit.For preventing that transferpump from stopping up, the sediment block canister and the vacuum breaker of filteration arranged in the design of the input aperture of transferpump.
The device of above-described elimination methane-generating pit scum silica frost, its outlet pipe are equipped with the valve that control enters the water sealed tank amount of liquid.
The device of above-described elimination methane-generating pit scum silica frost, its removable cover preembedded conduit is straight tube or S bend pipe, is connected with the reservoir outlet pipe.
Operating process of the present utility model and principle of work are: the zymogenic natural pond liquid that has of methane-generating pit bottom is extracted in the reservoir by transferpump, send in the water sealed tank from transport pipe again, when water sealed tank liquid completely after the natural pond hydrorrhea flow in the liquid tipping bucket of natural pond, natural pond liquid tipping bucket filled with fluid, the center of gravity imbalance, natural pond liquid will be poured methane-generating pit, scum silica frost is broken up, and make natural pond liquid zymophyte be distributed in scum silica frost and decompose scum silica frost and reach the purpose that solves scum silica frost crust problem.After stopping transferpump, under the internal gas pressure effect of pond, the discrepancy in elevation in the transfer lime between liquid level and the water sealed tank liquid level adds the normal atmosphere effect, internal and external pressure balance, during aerogenesis, biogas is pressed into transfer lime to the liquid in the water sealed tank again, and the liquid level discrepancy in elevation increases, internal and external pressure balance, so just sealed biogas in the pond, the biogas in the pond can not leaked into outside the pond by transfer lime.
The utility model has the advantages that:
1, do not need to add chemical substance, regular turn on pump 2-3 time weekly can stir the fermented liquid of fen, can reach the incrustive purpose of elimination scum silica frost again.
2, owing to adopt water sealed tank, utilize the principle of liquid envelope gas, make biogas be not easy to leak, safe and reliable.
3, biogas output does not add the improving more than 50% of this device than common.
4, improve the utilization ratio of fermentation raw material, and can use straw fermentation material in a large number.
