An integrated built-in fully automatic deodorizing manhole cover and its application method

Abstract

The invention relates to an integrated built-in fully automatic deodorizing manhole cover and its use method, comprising a manhole cover body, a fan, a deodorizing filler, and an automatic control system. There is an air duct installation hole in the center and a slag filter hole arranged around the air duct installation hole; an air duct is installed in the air duct installation hole, and the fan is fixed on the air duct; the air inlet at the lower end of the air duct is connected with the deodorizing filler Connection; the deodorizing filler includes a plant extract release box, a dry filter stuffing box, and an iron oxyhydroxide stuffing box arranged in sequence from top to bottom; the automatic control system includes a housing, a controller, a first receiving gas probe, and a second receiving gas probe. It has the advantages of reasonable structural design, convenient use, low maintenance cost, and a relatively high degree of automation and intelligence, and can effectively solve the problem of the overflow of odorous gas generated by municipal sewage under the manhole cover and affect the air quality.

Description

technical field [0001] The invention relates to the technical field of urban water supply and drainage, in particular to an integrated built-in fully automatic deodorizing manhole cover and a using method thereof. Background technique [0002] The main application fields of ductile ink manhole covers: municipal roads, highways, communications, electricity, tap water, residential areas, schools and other parks. At present, most of the sewage pipe manhole covers used on the road are ductile iron and circular manhole covers. Since municipal sewage flows under the manhole cover all the year round, the odorous gases such as hydrogen sulfide, ammonia and volatile organic compounds produced by municipal sewage in an anaerobic environment will be released from the surroundings and gaps of the manhole cover, seriously affecting the environment around the manhole cover, causing The phenomenon that the stench disturbs the people increases the work intensity of the pipeline cleaning wo...

AI Technical Summary

Problems solved by technology

As the municipal sewage flows under the manhole cover all the year round, the malodorous gases such as hydrogen sulfide, ammonia and volatile organic compounds produced by the municipal sewage in the anaerobic environment will be released from the surroundings and gaps of the manhole cover, seriously affecting the environment around the manhole cover, causing The phenomenon of stench nuisance, which increases the work intensity of the pipe cleaners and increases the operation cost

The present invention is proposed based on this research background, and aims to provide an integrated built-in fully automatic deodorizing manhole cover to solve the problem that the manhole cover emits peculiar smell into the air
