Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and specifically, to a waste gas treatment device. Background Art

[0002] Organic waste gas, particulate matter, sulfur oxides, and nitrogen oxides are listed as the four major air pollutants, and their emissions are relatively large among several air pollutants. In particular, industrial waste gas is an important source of air pollutants due to its large emissions. The most difficult to treat in industrial waste gas is organic waste gas. After organic waste gas enters the human body through the respiratory tract and skin, it can cause temporary or permanent lesions to the respiratory, blood, liver and other systems and organs of the human body. In particular, benzene-based aromatic hydrocarbons and polycyclic aromatic hydrocarbons such as benzo[a]pyrene can directly cause cancer in the human body, which requires high attention.

[0003] Organic waste gas mainly comes from the waste gas discharged during the production processes of the petroleum and chemical industries. It is characterized by a large quantity, large fluctuations in the organic matter content, being combustible when the concentration is high, and having certain toxicity, etc. Organic waste gas generally also has the characteristics of being flammable, explosive, toxic, harmful, insoluble in water, soluble in organic solvents, and difficult to treat. For waste containing both dust and organic pollutants, it usually needs to be removed step by step through a series of purification devices, and the process is complex and difficult to maintain.

[0012] The working principle and beneficial effects of the present utility model are as follows:

[0013] The waste gas treatment equipment provided by the present utility model, when in use, waste gas enters from the air inlet, after being filtered by the filter cartridge, dust is blocked outside the filter cartridge and accumulates in the ash discharge drawer. The waste gas after filtering the dust passes through the through hole of the first baffle, turns upward and then downward, and then passes through the channel below the second baffle to the absorption chamber. In the absorption chamber, the organic pollution components in the waste gas are absorbed by the activated carbon plates, and finally are discharged to subsequent equipment or the atmosphere through the exhaust port. When the activated carbon plates are saturated in adsorption, the steam spray pipe sprays steam onto the activated carbon plates, and the organic substances adsorbed in the activated carbon plates are desorbed, form a liquid mixture with the cooled steam and flow into the drainage hopper, and are collected and centrally treated after passing through the drainage port at the bottom of the drainage hopper. The waste gas treatment equipment of the present utility model has a good treatment effect on waste gas containing dust and low-concentration organic substances, and the treatment process is simple, and the waste gas treatment efficiency is high.
