Abstract

The present invention relates to the shell breaking method for marsh gas tank in countryside. Some marsh liquid is pumped and conveyed to the surface of marsh gas tank to prevent the formation of shell in the surface of the marsh gas tank. The marsh liquid may be from the present tank or other tank. The present invention has the beneficial effects of maintaining the ecological balance inside the march gas tank, maintaining the microbe environment inside the tank, taising the utilization of the material in the tank, increasing the output of the marsh gas and raising the quality of marsh gas.

Description

Shell cracking method for marsh liquid
Technical field
The present invention relates to the shell breaking method of a kind of rural area household methane tank.
Background technology
This phenomenon crusts on the methane-generating pit top layer, it is the ubiquitous problem of rural area household methane tank, its reason mainly is by due to pool-type structure and the fermentation raw material, methane-generating pit is in case crust, the aerogenesis effect will descend, disease pond and the useless pond of then becoming of a specified duration, the appearance of crust phenomenon has hindered the development of production and use of marsh gas industry, therefore methane-generating pit uses must the broken shell process, existing broken shell technology mainly contains mechanical stirring, electric energy stirs, water stirs, press the kickboard broken shell, cage anti-crust in center waits ways and means, and these methods have its advantage, and many limitation are more arranged, broken shell and mixing effect are not good enough, as mechanical stirring, electronic stirrings etc. are because of broken shell speed influences the life of anaerobion in the pond soon, so influence the fermenting process of biogas, and for example stir with extraneous clear water is broken, originally teaching others by his own example because of water is the hydrogen-oxygen molecular composition, can destroy the anaerobic environment in the pond, changes feed temperature and concentration, too much gas tank is diminished because of pool inner water simultaneously.
Summary of the invention
The shell cracking method for marsh liquid that the objective of the invention is to avoid above-mentioned weak point of the prior art and a kind of methane-generating pit is provided, it is use device and pipeline, extraction is also carried the crust layer of natural pond liquid to methane-generating pit, and is uniformly distributed on this crust layer, thereby prevents the crust of fen; The natural pond liquid that is extracted can be in this fen, also can be the natural pond liquid outside this fen.The present invention has following beneficial effect: effectively keep the eubiosis in the methane-generating pit, keep the microbial environment in the pond, improve raw material availability in the pond, realize the variation of fermentation raw material, improve the gas production rate of methane-generating pit and the quality of natural pond slag.
Embodiment
Below in conjunction with embodiment essentiality content of the present invention is described in further detail.
This shell cracking method for marsh liquid that is used for the rural area household methane tank is to utilize extracting device to extract natural pond liquid, and utilizes e Foerderanlage that natural pond liquid is transported on the crust layer of methane-generating pit, makes it uniform distribution and soak into to impact the crust layer.Owing to have in the liquid of natural pond after certain microorganism is transported on the crust face in working cycle, utilize it to decompose organic substance in the crust, the activation bacterium is handed over group, and solid substance density is changed, and quickens the organic substance degraded.Can remove crust like this, make that vent box gathers on the gas, utilize gas, can make full use of the plant cobalt blue pigment again, realize the variation of fermentation raw material, gas production rate is improved.

Claims (2)

1. be used for the shell cracking method for marsh liquid of household methane tank in the rural area, it is characterized in that: use device and pipeline, extract and also carry the crust layer of natural pond liquid to methane-generating pit, and be uniformly distributed on this crust layer, thereby prevent the crust of fen.
2. shell cracking method for marsh liquid according to claim 1 is characterized in that: the natural pond liquid that is extracted can be in this fen, also can be the natural pond liquid outside this fen.
