Description

Urban underground pipeline biogas disposal and utilization device Technical Field The utility model relates to the technical field of methane treatment and reutilization of underground pipelines, in particular to a methane treatment and utilization device for urban underground pipelines. Background Domestic sewage, industrial wastewater and the like of urban underground pipelines generate a certain amount of biogas in an anoxic environment, wherein the main components comprise 50-70% of methane, 30% of carbon dioxide, a small amount of hydrogen sulfide, hydrogen, nitrogen, carbon monoxide and the like, and in addition, the leakage of pipeline gas can cause the aggregation of abnormal combustible gas and easily form an explosion hazard source. In particular, in recent years, rainwater and sewage are split in urban construction, the concentration of organic matters in sewage in a domestic sewage pipeline is increased due to lack of flushing of rainwater, the biogas generation amount and concentration are high, and the explosion risk is increased. At present, risks caused by biogas are prevented, namely, a small water channel is dredged regularly, garbage accumulation and fermentation are avoided, biogas generation is reduced, a monitoring and early warning mechanism is built, a combustible gas and toxic gas monitoring and early warning mechanism is built in a sewer, and unmanned remote real-time monitoring is implemented. However, the actual control is not in place, and in recent years, because of the occurrence of accidents of methane explosion of underground pipelines, a plurality of property loss and casualties are caused. Because the underground pipeline has wider distribution area, biogas and other harmful gas components in the pipeline are uneven, and the treatment has certain difficulty.
