Tail gas collection and purification system in wastewater treatment process

Abstract

The invention discloses a tail gas collection and purification system in the waste water treatment process, which comprises a waste water treatment tank, a collection chamber located on the upper part of the inner cavity of the waste water treatment tank and surrounded by a hoarding plate, and a gas collection chamber accommodated in the collection chamber; There is a gap at the bottom of the gas chamber to communicate with the waste water treatment tank. There is a through groove on the gas collection chamber, which communicates with the collection chamber. The space, the through groove is located on the outer wall of the space close to the side of the gap; the through groove is closed by applying force to the side of the diaphragm facing the through groove; a demister is installed in the waste water treatment tank; the demister is set on the liquid It is composed of the demister net on the surface and the moving grid that is located on the upper part of the demister net and slides up and down along the tank wall of the wastewater treatment tank. The invention improves the sealing of the waste water treatment tank and the waste gas collection structure, adopts the diaphragm structure combined with the air pressure to guide the gas, makes the waste gas collection smoother, and the diaphragm structure also protects the gas outlet.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a tail gas collection and purification system in a waste water treatment process. Background technique [0002] The stench and toxic and harmful gas pollutants produced by the adjustment tank, anaerobic tank, aeration tank and other facilities in the wastewater treatment station of the industrial wastewater treatment station seriously pollute the surrounding environment. The wastewater treatment process and wastewater quality of industrial wastewater treatment stations directly affect the pollutants contained in the exhaust gas. These pollutants generally contain hydrogen sulfide, ammonia, mercaptans, sulfides, hydrocarbons, benzene, toluene, and organic halogen derivatives. Volatile organic compounds (VOCs); these pollutants are carcinogenic, affect the human nervous system and blood system, and seriously damage human health. In addition, the acid gas contained in th...

The wastewater treatment process and wastewater quality of industrial wastewater treatment stations directly affect the pollutants contained in the exhaust gas. These pollutants generally contain hydrogen sulfide, ammonia, mercaptans, sulfides, hydrocarbons, benzene, toluene, and organic halogen derivatives. Volatile organic compounds (VOCs); these pollutants are carcinogenic, affect the human nervous system and blood system, and seriously damage human health. In addition, the acid gas contained in the exhaust gas is also corrosive to the plant equipment;

[0003] This kind of waste gas is directly produced from the liquid and is in an environment rich in microorganisms. Therefore, in the waste gas collection process, there will be impurities remaining at the air inlet. After a long time, manual cleaning is required, but cleaning is easy to damage the wastewater treatment pool. The tightness of the seal, so this part needs to be improved
