Problems solved by technology

[0002] Salicylic acid will produce waste gas during production and processing, and the direct discharge of waste gas will bring serious pollution to the environment. It is necessary to purify the waste gas. Salicylic acid waste gas contains a large amount of irritating odor gas, which affects the environment and causes environmental pollution. Pollution, most enterprises now use incinerators to treat these exhaust gases and discharge them after meeting the emission standards. The incinerators directly incinerate the gases. During the incineration process, the heat energy consumption is high, the exhaust gas temperature is also high, and incineration produces a large amount of carbon dioxide. Cause secondary pollution to the environment

Abstract

The invention provides a deodorization device for waste gas generated by salicylic acid production and a deodorization technology thereof. The deodorization device comprises an activated sludge deodorization device and three-phase multimedium catalytic oxidation equipment; after the waste gas is cooled, the activated sludge deodorization device is used for performing primary deodorization treatment on the waste gas, then the three-phase multimedium catalytic oxidation equipment is used for performing secondary treatment on the waste gas; the waste gas cannot be deodorized sufficiently through the single use of the activated sludge deodorization device, the usage amount of agents is large through the single use of the three-phase multimedium catalytic oxidation equipment, and by using the two in combination, the use amount of the agents is saved and the deodorization rate of the waste gas is improved.

Description

technical field [0001] The invention relates to the technical field of salicylic acid production and processing, in particular to a salicylic acid production waste gas deodorization device and a deodorization process thereof. Background technique [0002] Salicylic acid will produce waste gas during the production and processing process, and the direct discharge of waste gas will bring serious pollution to the environment. It is necessary to purify the waste gas. Salicylic acid waste gas contains a large amount of irritating malodorous gas, which will affect the environment and cause environmental pollution. Pollution, most enterprises now use incinerators to treat these waste gases and discharge them after reaching the emission standards. The incinerators directly incinerate the gases. During the incineration process, the heat energy consumption is high, the exhaust gas temperature is also high, and incineration produces a large amount of carbon dioxide. Cause secondary pol...
