Problems solved by technology
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

The invention discloses a tail gas collecting and purifying system used in a wastewater treatment process. The tail gas collecting and purifying system comprises a wastewater treatment tank, a collecting cavity and a gas collecting bin, wherein the collecting cavity is positioned at the upper part of an inner cavity of the wastewater treatment tank and is defined by coamings; the gas collecting bin is contained in the collecting cavity; a gap is formed in the bottom of the gas collecting bin and communicates with the wastewater treatment tank; a through groove is formed in the gas collecting bin and communicates with the collecting cavity; a diaphragm is arranged in the gas collecting bin and divides the interior of the gas collecting bin into two spaces which do not communicate with eachother, and the through groove is located in the outer wall of the space close to one side of the gap; force is applied to one side, facing the through groove, of the diaphragm to close the through groove; a demister is mounted in the wastewater treatment tank; and the demister consists of a defoaming net arranged on the surface of a liquid level and a movable grid which is positioned at the upperpart of the defoaming net and slides up and down along the wall of the wastewater treatment tank. According to the invention, the sealing of the wastewater treatment tank and a waste gas collecting structure are improved, and a diaphragm structure is combined with gas pressure to guide gas, so waste gas collecting is smoother, and the diaphragm structure also protects a 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...
