Problems solved by technology

[0004] However, the waste gas recovery and utilization device only has a single scope of application, and the waste gas is only subjected to decompression and condensation treatment. The treatment is not thorough, and the emission reduction does not fundamentally change the composition of the emission, which inevitably pollutes the environment. Not suitable for popularization and application, especially not suitable for application in irrigation areas that store a variety of chemicals

Abstract

The invention relates to a waste gas recovery processing system and a recovery processing technique of the waste gas, in particular to the waste gas recovery processing system and the recovery processing technique of the waste gas in areas storing a variety of chemical tanks, wherein the system comprises a waste gas conveying device and a purified gas discharging device, and comprises an adsorption device and a catalytic oxidization device connected with one another; the waste gas conveying device is connected with the adsorption device; the purified gas discharging device is connected with the adsorption device and the catalytic oxidization device respectively; the adsorption device is the adsorption device having more than one stage; and a circulatory recovery processing technique combining adsorption with catalytic oxidization is realized by the system. According to the waste gas recovery processing system and the recovery processing technique, the recovery processing problem of organic chemicals in the waste gas is sufficiently resolved, the environmental pollution in the chemical kettle area and around the chemical kettle area is effectively avoided, and the environment protection and energy saving effect is obvious; and therefore, the system and the technique are suitable for recycling and processing the waste gas produced by various chemical tanks with different properties such as floating roof tanks and vault roof tanks.

Description

technical field [0001] The invention relates to a waste gas recovery and treatment system and a recovery treatment process thereof, in particular to a waste gas recovery treatment system and a recovery treatment process for storing various chemical product tank farms. Background technique [0002] At present, chemical products are widely used, and the land used for storage is also increasing day by day, forming many storage irrigation areas of different sizes. In these chemical storage irrigation areas, most of the different chemicals are stored together in large quantities, and the chemicals all have different degrees of volatilization, which not only causes waste of chemicals, but also pollutes the air in and around the irrigation area, especially organic chemicals. In the storage irrigation area, such pollution and waste are particularly serious. If not treated in time, the volatilized and / or spilled chemicals may react with each other, causing even more serious impacts. ...
