Waste gas treatment process

Abstract

The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment process which comprises the following steps: S1, treating harmful gas by an absorption method, arranging a closed hood on a vacuum pump room, arranging an air outlet in the upper part of the closed hood to discharge waste gas generated in the room, keeping a certain negative pressure in theroom, and enabling the discharged waste gas to enter a filler spraying absorption tower; S2, introducing the waste gas in an absorption tower for purification treatment; S3, introducing the treated waste gas in a wire mesh demister to be subjected to mesh removal treatment; S4, enabling the absorption liquid absorbing the waste gas to flow into a tower bottom circulating alkali liquor tank, pumping out the absorption liquid by using a corrosion-resistant alkali liquor pump, feeding the absorption liquid into the absorption tower again, and continuously absorbing harmful gas in the waste gas byrepeating the steps; and S5, discharging the gas through a peculiar smell control box. The process is simple, the system composition is easy to realize, the purification efficiency can reach about 90%, entrainment in gas is separated, equipment corrosion is reduced, the service life of equipment is prolonged, meanwhile, odor can be thoroughly removed, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment process. Background technique [0002] If the exhaust gas is directly discharged into the atmosphere without treatment, it will inevitably pollute the surrounding environment and affect the lives of the surrounding residents. [0003] In the prior art, waste gas treatment is difficult, and for enterprises, the cost is high, and the purification rate of most waste gas treatment is low, and at the same time, part of the odor is still left in the discharged gas, which pollutes the environment. Contents of the invention [0004] The purpose of the invention is to solve the shortcoming that exists in the prior art, and a kind of waste gas treatment process that proposes. [0005] In order to achieve the above object, the present invention adopts the following technical solutions: [0006] A waste gas treatment process, comprising the following ste...
