Description

Biogas generation and gas supply equipment

technical field

The utility model relates to the field of biogas equipment, in particular to a biogas generation and gas supply equipment.

Background technique

Biogas is a renewable and clean energy source. Since this gas was first discovered in swamps, it is called biogas. Biogas is a combustible gas produced by organic matter under the conditions of isolation from air and certain temperature, humidity, pH, etc., through the action of biogas bacteria. Biogas is a mixed gas whose main component is methane. There are many raw materials that can be used for biogas fermentation in rural areas, the most commonly used are human and livestock (pigs, cattle, sheep, horses, chickens, ducks) manure and various crop straws (straw, wheat straw, corn straw, rapeseed, soybean, peanut straw), All kinds of green weeds, rotten vegetables and leaves, water hyacinth, waste residue, waste water (distiller's grains, waste residue water from making tofu), etc.

At present, in the rural areas of our country, organic matter such as human and animal manure is mainly used to produce flammable gas through microbial energy metabolism and respiration in biogas digesters under anaerobic conditions. The use of biogas digesters has many advantages in addition to fully saving costs. After the human and livestock manure is put into the biogas digester for fermentation, it can effectively kill the bacterial, viral and parasitic disease sources parasitic in human and livestock manure. . Under the closed conditions of the biogas digester, the inert substances released by microbial decomposition and energy metabolism and respiration can be recycled in the pond, and there is no environmental pollution caused by the stacking method; the waste of human and animal manure after fermentation in the biogas digester can be directly used for crops Fertilizer, fish farming, pig feeding, seed soaking or direct discharge into rivers will not produce secondary pollution; the use of biogas in rural areas can also effectively reduce pink eye disease, asthma and other diseases caused by traditional cooking smoke and fire.

The traditional biogas fermentation tanks in rural areas of our country usually adopt a deep well structure. The deep well structure fermentation tanks are buried underground. If the pollution is not cleaned in time, it is easy to cause a biogas explosion. Since the cleaning needs to be carried out manually to the bottom of the pond, there are often incidents of methane poisoning and even death of personnel who go down to clean the pond. And because the fermentation tank is located underground, it is easy to cause accidents that children fall into the fermentation tank after the pool cover is opened. In addition, since the usual biogas supply uses a gas pipeline to directly transport the biogas from the fermentation tank to the end-use terminal, since the biogas in the fermentation tank contains soda water and a small amount of hydrogen sulfide and other substances, the biogas that has not undergone steam-water separation and desulfurization is burned Its utilization rate is greatly affected. At the same time, because the existing biogas fermentation tank is located underground, it is relatively difficult to choose its terrain, and the construction work is relatively large.
