Embodiment Construction

[0042] The design idea of ​​the applicant is to combine the principle of aerodynamics and adsorption separation, use the twin-turbine fan with a large air intake to inhale air in the inspection well 7, and send the gas out of the inspection well 7 through the air delivery pipe 10, in order to prevent toxic gases or The irritating gas produces secondary pollution, and the wellhead is equipped with a filter device and an adsorption device to remove hydrogen sulfide, ammonia, methane and other gases. The equipment has strong mobility, flexible connection, simple structure, compact layout, high space utilization rate, convenient operation, environmental protection and energy saving.

[0043] The gas in the inspection well 7 can be sucked, filtered and adsorbed by using the device, and the content of harmful substances in the treated gas is small, which meets the discharge standard.

[0044] like Figure 1 to Figure 3 As shown, a device for harmless removal of harmful gases in urb...

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...
