A harmless removal device for harmful gases in urban sewage pipelines

Abstract

The invention discloses a harmlessness removal apparatus for harmful gas in city sewage pipeline, which comprises an air exhaust apparatus in an inspection well, the air exhaust apparatus extracts harmful gas in the inspection well, and is introduced to gas processing equipment arranged at port of the inspection well through an airduct, the gas processing equipment comprises a filtering apparatus and an adsorption apparatus, harmful gas passes through the filtering apparatus and the adsorption apparatus for processing harmful gas in order, and the processed gas is discharged in atmosphere. The harmlessness removal apparatus can be used for fast assembly and installation in the inspection well, and is capable of performing rapid and effective elimination as well as harmlessness processing on harmful gas in the well, land occupation of whole apparatus is little, the harmlessness removal apparatus has less influence on public transport, and work efficiency under well can be ensured.

Description

technical field [0001] The invention relates to a gas purification and discharge device for urban sewage pipes, in particular to an assembly-integrated device that can be assembled into an inspection well to extract toxic and harmful gases from the pipeline through a turbo blower and discharge them after harmless treatment. technical background [0002] Urban sewage pipes, that is, urban sewer systems, are mainly used to collect and discharge urban rainfall, urban residents' domestic sewage and industrial production wastewater, and are an important part of urban infrastructure. According to investigation and research, the existing drainage system design mechanism of Chinese cities is relatively complicated, especially in the old urban areas inside the city. into the design mechanism of the urban sewage system. The sewage pipes in the old city are in disrepair for a long time, the pipe diameter is small, the management is not standardized, and the cleaning is less, and a lar...
