Device and method for processing municipal utilities foul gas

Abstract

The invention belongs to a technical field of waste gas treatment, in particular to a device used for treating the malodorous gas of municipal facilities and a method thereof. The device of the invention consists of a filter screen, a plasma reactor, a honeycomb activated carbon bed and a blower which are connected in sequence; wherein the plasma reactor adopts the structure form of a double medium barrier discharge plasma and is formed by the combination of a plurality of plasma reaction tubes; the honeycomb activated carbon bed is an absorption-catalysis oxidative bed and adopts the honeycomb activated carbon as a filling layer. The particles such as the dust in the waste gas are filtered out through the filter screen and enter into the plasma reactor, and a series of reactions occur to the malodorous matter in the bombardment of high energy electrons, and a little un-reacted malodorous matter is further treated through the honeycomb activated carbon bed. The blower which is arranged at the back of the device thus ensures the reaction device in negative pressure conditions so as to avoid the leakage of the malodorous gas. The device and the method provided by the invention have a large processing capacity of the malodorous gas and are high in processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a device and method for treating malodorous gas in municipal facilities. Background technique [0002] With the enhancement of environmental protection awareness of our residents, the stench problem of municipal public facilities such as sewage treatment plants, sewage pumping stations, public toilets and feces transfer stations will receive more and more attention, and has become one of the focuses of residents' complaints. The main reason for the odor of malodorous substances is to contain characteristic odorous groups. Odor molecules containing odorous groups interact with olfactory cells, and transmit information to brain nerves through olfactory nerves, thereby completing the identification of odors. Common odorous groups include sulfur-containing compounds such as sulfur groups, mercapto groups, and thiocyano groups, and oxygen-containing compounds ...

AI Technical Summary

Problems solved by technology

[0007] 1. The tail gas after dielectric barrier discharge plasma treatment contains a large amount of ozone, which cannot be fully utilized and causes secondary pollution;

[0008] 2. The discharge area is small, the gas reaction time is short, and the odorous substances are discharged with the exhaust gas if they fail to fully react;
