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 (VOC) such as 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

Embodiment
[0016] Embodiment: This embodiment refers to Figure 1-2 As shown: it includes a waste water treatment tank 1 and a collection device 4 located on the upper part of the inner cavity of the waste water treatment tank 1. The collection device 4 is a hollow structure, and an opening 43 is opened on the outer wall of the collection device 4. The collection device 4 4 is fixedly installed with a rectifying bin 41 opening downwards, the outer wall of the rectifying bin 41 and the inner wall of the collecting device 4 form a cyclone flow field 42, and the fluid entering from the port 43 passes through the cyclone flow field 42 to form a cyclone and then flows out of the rectifying bin The bottom of 41 enters the rectifying chamber 41;
[0017] refer to figure 1 As shown, the collecting device 4 and the rectifying bin 41 are all conical structures, which combine with the formed cyclone flow field 42 to actually constitute a centrifugal separator, and a blanking area can be set at the...

The invention discloses a tail gas deodorization system in pharmaceutical and chemical wastewater treatment. The system comprises a wastewater treatment tank and a collecting device located at the upper part of an inner cavity of the wastewater treatment tank, wherein the collecting device is of a hollow structure, a through opening is formed in the outer side wall of the collecting device, a rectifying bin with a downward opening is fixedly installed in the collecting device, a cyclone flow field is formed by the outer wall of the rectifying bin and the inner wall of the collecting device, and a fluid entering from the through opening enters the rectifying bin from the bottom of the rectifying bin after forming cyclone through the cyclone flow field; and a sealing film is arranged on theouter edge of the collecting device, the top of the rectifying bin communicates with a gas conveying pipeline, an induced draft fan is installed on the gas conveying pipeline, and the output end of the gas conveying pipeline is connected with an oxidation tower deodorization device. The sealing of the wastewater treatment tank and a waste gas collecting structure are improved, a traditional valvestructure is canceled, and a diaphragm structure is combined with gas pressure to guide gas, so waste gas collection is smoother, and a gas outlet is protected by the diaphragm structure.
Description
technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a tail gas deodorization system in the treatment of pharmaceutical and chemical wastewater. Background technique [0002] Pharmaceutical and chemical wastewater treatment stations generate stench and toxic and harmful gas pollutants from regulating tanks, anaerobic tanks, aeration tanks and other facilities during the wastewater treatment process, seriously polluting 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 (VOC) such as these pollutants are carcinogenic, affect the human nervous system and blood system, and seriously damage human health. In additio...
