Problems solved by technology

[0004]1. The exhaust gas in the factory production is generally only discharged into the air after simple treatment such as simple water spray equipment or activated carbon adsorption, and the exhaust gas often does not meet the standard , containing toxic and odorous substances, will still pollute the environment and endanger human health; in addition, some chemical products will be mixed in the exhaust gas and discharged, and the yield will be affected
[0005]2. Due to the technical problems of the treatment facilities themselves, the treatment rate of factory waste gas is not high or the treatment cost and investment cost are too high
In this treatment method, the biological treatment takes a long time and the treatment capacity is small, and it is powerless to deal with a large amount of waste gas discharged from some continuous production factories; in addition, the organic waste gas treatment device is aimed at organic waste gas, and cannot treat some inorganic polluting gases to reach the national level. emission standards

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and relates to a waste gas treatment device and a corresponding pharmaceutical waste gas treatment process, in particular to a photocatalytic purification device for treating pharmaceutical waste gas and a corresponding treatment process. Background technique [0002] With the development of society, the worldwide environmental crisis is becoming more and more serious, and people's awareness of environmental protection is becoming stronger and stronger: on the one hand, the rapid economic development produces a series of pollutants, such as the emission of volatile organic compounds ( VOC) and sulfur compounds, which are the chief culprits that endanger human health. VOC invades the human nervous, blood, respiratory and reproductive systems, especially the common triphenyl (benzene, toluene and xylene) exhaust gas, which penetrates into the body through breathing and skin, causing diz...
