The utility model relates to a system for absorbing, storing and reusing harmful gases in municipal sewer system

Abstract With the acceleration of urbanization, the scale of urban sewage drainage systems is also getting larger and larger. The pipeline sewage carries a large amount of domestic garbage and sludge after being decomposed by microorganisms, which produces a large amount of toxic, harmful, flammable and explosive gases, such as methane (CH4) and hydrogen sulfide (H2S). When these gases are concentrated in the drainage pipe, it is a serious safety hazard. If these gases are directly discharged into the atmosphere, it will pollute the environment on the one hand, and waste resources on the other. In order to solve this important problem, this paper designs a system for the absorption, storage and reuse of harmful gases in urban sewage pipelines for hydrogen sulfide and methane. The hydrogen sulfide and methane gas are absorbed by the gas adsorption device, and then the gas is pumped out of the adsorption device by a solar driven pump and stored in the gas storage device.
