This led to the tragedy of four deaths of three generations of biogas digesters.

Effect of purchasing biogas digesters by the state

Nowadays, biogas digesters are installed in many rural areas, and the pigsty, toilet and biogas digester at home are all built together, which not only brings convenience to farmers' daily life, but also brings a lot of economic benefits.

First of all, the construction of biogas digesters has solved the fuel problem in rural areas. In rural areas, many families build biogas digesters as living fuel. Biogas is used for cooking and burning, which is convenient and labor-saving.

Secondly, after purchasing biogas, a large number of crop straws and livestock manure are put into biogas digesters for closed fermentation, providing a large number of high-quality fertilizers. These fertilizers are excellent organic fertilizers for various crops, flowers, fruit trees and vegetables.

It promotes the growth and development of various crops. The use of biogas fertilizer reduces the use of pesticides and is conducive to green production.

Third, after the biogas digester is installed, it will be better managed near the house. The supply of fuel and fertilizer will save labor and capital expenditure.

Cases of methane poisoning often occur. What should I pay attention to?

Although methane does bring us a lot of convenience, in recent years, vicious cases of methane poisoning have occurred from time to time. What should I pay attention to?

In fact, almost all methane poisoning incidents are caused by lack of self-protection and safety knowledge.

Due to the continuous fermentation of crops and manure in biogas digesters, a toxic gas-hydrogen sulfide is produced in biogas. It is a colorless and warm gas, like rotten eggs. If the concentration of hydrogen sulfide in the air exceeds 0. 1%, people will die.

In addition, biogas fermentation consumes a lot of oxygen and releases carbon dioxide. The oxygen content in the air increases, the carbon dioxide content decreases, and people's breathing is suppressed and they die of paralysis.

Many people immediately went to the scene of the accident to rescue after methane poisoning, which eventually led to saving people and committing suicide.

Ventilation should be done before entering the pool, and the water inlet, water outlet and movable cover should be opened for ventilation.

Before entering the operation, the quality of gas in the pool can be monitored. Put chickens, geese and other small animals into the biogas digester, and re-enter the pool after no adverse reactions.

It is best not to go alone during the operation. Please wear protective tools when operating. It is best to tie a rope on the pool and let outsiders hold it.

It is best not to operate the swimming pool for too long. Once you feel something is wrong, climb out of the swimming pool in time for air.

After the accident is discovered, people outside the swimming pool cannot directly enter the swimming pool for rescue. Rescuers must wear oxygen masks, give artificial respiration after rescue, and call 120 emergency number.
