Deodorization device of sewage treatment tank

Abstract

The invention discloses a deodorization device of a sewage treatment tank. The device comprises a gas collecting hood mounted above the treatment tank through a support rod, a reduction gearbox, a disinfection box and a drying box, an electric fan is mounted on the inner wall of the gas collecting hood through a fixing rod, and one end of the top of the gas collecting hood communicates with the inner wall of one side of the reduction gearbox through an air inlet pipe; and first inclined plates distributed at equal intervals are welded to the inner wall of the top of the reduction gearbox, second inclined plates distributed at equal intervals are welded to the inner wall of the bottom of the reduction gearbox, and the inner wall of the other side of the reduction gearbox communicates with the inner wall of one side of the disinfection box through a connecting pipe. When the deodorization device is used, odor generated by sewage can be blown into the reduction gearbox through a fan and then introduced into the disinfection box, disinfectant is sprayed out through a spray head to disinfect the odor, after disinfection, the odor is dried through an electric heating wire, then the odor is adsorbed for multiple times through activated carbon in the multiple net cages, and after the odor is eliminated, the air is exhausted through an exhaust pipe, so that air near a treatment plant is protected.

Description

technical field [0001] The invention relates to the technical field of deodorization, in particular to a deodorization device for a sewage treatment pool. Background technique [0002] During the process of sewage treatment in the sewage treatment tank through biochemical and aeration methods, a large amount of odor will be generated. Due to the large area of ​​the sewage treatment tank, it is difficult to collect the odor generated during the treatment process. In addition to cost factors, open air discharge is generally used These odors not only smell bad, but also contain a large number of bacteria, which cause serious pollution to the air near the treatment plant. [0003] For this reason, the Chinese patent (application number 201921779864.2) discloses "a deodorization device for sewage treatment tanks". This device is suitable for retrofitting and assembly on old sewage treatment tanks. Or rewinding, activated carbon can be replaced and used repeatedly by the activati...

[0002] During the process of sewage treatment in the sewage treatment tank through biochemical and aeration methods, a large amount of odor will be generated. Due to the large area of ​​the sewage treatment tank, it is difficult to collect the odor generated during the treatment process. In addition to cost factors, open air discharge is generally used The way to deal with these odors, these odors not only smell bad, but also contain a large number of bacteria, which will cause serious pollution to the air near the treatment plant

[0003] For this reason, the Chinese patent (application number 201921779864.2) discloses "a deodorization device for sewage treatment tanks". This device is suitable for retrofitting and assembly on old sewage treatment tanks. Or rewinding, activated carbon can be replaced and used repeatedly by the activation furnace, which effectively controls the overall cost of the deodorization device, but the device only covers the sewage treatment tank with a cover cloth and adds activated carbon, resulting in poor deodorization effect and no sterilization. The effect is to treat the symptoms but not the root cause, and cannot effectively deal with the odor
