Embodiment Construction

[0042] The applicant’s design idea is to combine the principles of aerodynamics and adsorption and separation, and use a twin-turbo fan with a large air intake to suck in the inspection well 7, and send the gas out of the inspection well 7 through the air duct 10, in order to prevent toxic gases or Irritating gas produces secondary pollution, and the wellhead is equipped with filtering devices and adsorption devices to remove hydrogen sulfide, ammonia, methane and other gases. The equipment has strong mobility, flexible connection, simple structure, compact layout, high space utilization, convenient operation, environmental protection and energy saving.

[0043] The device can be used to suck, filter and adsorb the gas in the inspection well 7, and the treated gas contains less harmful substances and meets the emission standard.

[0044] Such as Figure 1 to Figure 3 As shown, a device for harmless removal of harmful gases from urban sewage pipelines includes an air extraction dev...

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 assemblable integrated device that can be put into an inspection well to extract toxic and harmful gases from the pipeline through a turbo fan and discharge after harmless treatment. technical background [0002] Urban sewage pipes, or 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 textual research, the existing drainage system design mechanism in Chinese cities is relatively complicated, especially in the old urban areas within the city. Due to the problems in the design years, most of the drainage methods are combined with rain and sewage, and even industrial wastewater is directly discharged without treatment. Design mechanism into the urban sewage system. Sewage pi...
