Waste gas treatment system

Abstract

The invention discloses a waste gas treatment system, which comprises a starting end gas conveying pipe, a waste gas purification tower, a middle section gas conveying pipe, a chimney and a control cabinet, wherein the starting end gas conveying pipe is connected with the lower portion of the waste gas purification tower, the upper portion of the waste gas purification tower is sequentially connected with an active carbon adsorption cabinet and UV photo-oxidation catalytic treatment equipment through the middle section gas conveying pipe, the outlet of the UV photo-oxidation catalytic treatment equipment is connected with the chimney, a plurality of rotational flow plates and a plurality of spraying heads are arranged in the waste gas purification tower at intervals in a staggered manner,the tail end of the middle section gas conveying pipe is connected with a gas return pipe through a steering valve, the gas return pipe is communicated with the starting end gas conveying pipe, and the steering valve is controlled by the control cabinet. The waste gas treatment system is convenient to operate and simple to manage, can prevent the phenomenon that the tail gas does not reach the standard and is leaked, can save the cost to the maximum extent, and realizes efficient treatment of the tail gas.

Description

technical field [0001] The invention relates to a waste gas treatment system, which belongs to the technical field of atmospheric environmental protection. Background technique [0002] In recent years, my country has carried out a lot of research and development work in pollution emission control technology and other aspects, and has achieved many new results, and there are many equipment for industrial waste gas treatment. However, some devices are often in the operation stage or after long-term operation, due to internal and external factors, the system stability is insufficient, the gas treatment is not complete, the oxidation reaction is not complete, and the concentration of exhaust pollutants discharged by the final system exceeds the standard, which cannot meet the current requirements. emission standards for environmental protection requirements. Some devices will be accompanied by a lot of mist during the treatment process, and the traditional tail gas purificatio...

Problems solved by technology

However, some devices are often in the operation stage or after long-term operation, due to internal and external factors, the system stability is insufficient, the gas treatment is not complete, the oxidation reaction is not complete, and the concentration of exhaust pollutants discharged by the final system exceeds the standard, which cannot meet the current requirements. Emission standards for environmental protection requirements

Some devices will be accompanied by a lot of mist during the treatment process, and the traditional exhaust gas purification process will lead to a decrease in catalyst activity or even complete failure in the presence of a large amount of water vapor, resulting in the exhaust gas cannot be effectively treated
