1. The working principle of the biogas digester: when the biogas is generated in the pool, the biogas in the gas storage room continues to increase, and the pressure continues to increase, forcing the liquid level in the main tank to drop and squeezing out a part of the material liquid into the water pressure room. When people turn on the stove, the pressure in the digester gradually drops, and the liquid flows back to the main pond between the water pressure.
In this way, the gas is continuously produced and used, so that the pressure balance between the fermentation room and the discharge room is always maintained.
2. Principle of biogas fermentation:
The process of microbial metabolism is called fermentation, which refers to the process of organic substances under certain moisture, temperature and anaerobic conditions, through the catabolism of various microorganisms, and finally the process of biogas. There are three stages to this process:
1) Liquefaction stage: provide nutrients for methanogens and create suitable anaerobic conditions for methanogens to eliminate some poisons.
2) Acid-producing stage.
3) Methanogenic stage: methanogenic flora, using the small molecule compounds decomposed and transformed in the above two steps to generate methane.
P.S. The fermentation room and gas storage room are called the main pool.
The function of the water pressure room is to store the material and liquid extruded from the main pool; Second, it plays the role of pressing out the biogas when using gas.

Biogas digester is a facility for the production of biogas, the use of the principle of microbial fermentation, the production of a combustible gas, to improve the living fuel needs of rural families, improve the rural living environment, biogas can replace firewood for cooking, boiling water, etc.
1. BiogasThe main component of biogas is methane, which can be fermented by microorganisms, and animal manure contains a large number of bacteria and methane bacteria, and biogas can be collected by animal manure fermentation, so biogas digesters are generally built together with toilets and pigsty in rural areas.
2. SignificanceThe biogas digester not only improves the living environment in rural areas, but also makes full use of resources. A family of five is suspicious of the need to build a 6-cubic-meter biogas digester, which can provide fuel for cooking and lighting for 9 to 11 months a year, as long as the raw materials are sufficient.

1) Provide cheap and high-quality fuel to the countryside. A 6,10 cubic metre digester for a family of 3,5 can provide fuel for cooking and lighting for 9 to 11 months a year, as long as the raw materials are sufficient. Since biogas slurry can be used as pesticides, fertilizers, feed, etc., it can also be used as a resource to achieve the purpose of saving.
2) Change the old living habits of farmers and improve the living environment in rural areas. The biogas digester is built together with the toilet and pigsty, which is not easy to breed mosquitoes and has no odor. It will play an important role in the eradication of infectious diseases such as schistosomiasis and hookworm disease.
In addition, due to frequent human activities, a large amount of energy consumption, a large number of open stacking of straw and livestock and poultry manure, etc., resulting in a large amount of carbon dioxide emissions, aggravating the greenhouse effect. The use of biogas digesters can reduce the above problems to a certain extent.
3) Promote the development of ecological agriculture and animal husbandry. The waste from the biogas digester is biogas slurry and biogas residue, which can be used as pesticide additives, fertilizers, feed, etc., which greatly reduces the harm caused by chemical fertilizers and pesticides, and is conducive to the production of green products and pollution-free products.

It is a combustible gas produced by organic substances in an anaerobic environment, under certain temperature, humidity and pH conditions, through microbial fermentation. Because this gas was first found in swamps, lakes, ponds, people call it biogas.
Biogas, as the name suggests, is the pure transportation of gas in swampy wetlands. It is often seen that bubbles come out of the swamp pants dust, sewage ditches or manure tanks, and if we strike a match, we can light it, which is a natural occurrence of biogas.
Biogas contains a variety of gas components, and the main component of Lingliang is methane. The process by which biogas bacteria decompose organic matter to produce biogas is called biogas fermentation.
Biogas is a colorless, odorous, toxic and odorous gas, and its main component methane is a colorless, tasteless, odorless and non-toxic gas at room temperature.
The method I used: dissolve a handful of laundry detergent in a bucket of warm water and sprinkle it on the area where it may leak (where the smell is heavier), if it bubbles, it means that it is leaking. >>>More
household biogas digester filler; Eighty percent of the volume of the pond is filled at one time, and the dry matter content is 100 percent to 6 to 8, and the details are added.
It's too broad. I will introduce you to the simple process of the household biogas digester for your reference: >>>More
Increase the fermentation temperature of the digester.
It is recommended that you choose a new type of biogas tank now, the advantage is simple, easy to build its nature is the same as the shape of the septic tank we use now, there is no old-fashioned complexity, its effect is much better than the original, you can save materials, its materials are, red bricks, cement, sand, stones, a small amount of steel can be.
