The leachate treatment system of the incineration plant generally needs an anaerobic process, biogas can be generated in the fermentation process of the anaerobic process, but the biogas generation speed can be fluctuated due to the influence of external operation environment, and the biogas belongs to inflammable and explosive gas, so that a biogas water-sealed tank is generally used in the anaerobic process of sewage treatment, and the purposes of stabilizing the pressure in the anaerobic reactor, isolating a fire source, preventing tempering and the like are achieved.

Working principle of a traditional biogas water-sealed tank: the combustible gas (methane) generated in the production process enters the bottom of the tank body through the inlet pipeline of the water-sealed tank, and the bottom of the air inlet pipe is positioned below the liquid level. The combustible gas containing hydrogen sulfide rises to the upper space of the liquid surface of the water-sealed tank from the bottom of the water area, and is discharged from an outlet pipeline at the upper part of the water-sealed tank after the upper space forms certain gas pressure. When tempering occurs, the water naturally forms a barrier to gases. In actual work, the height of the water tank inside the water sealed tank is fixed, and the gas pressure inside the tank body cannot be adjusted according to the use requirement, so that the water sealed tank is inconvenient to use.
