A large amount of VOCs waste gas is generated in the production of composite materials, and the types of waste gas are numerous and complex, mainly including benzene, ammonia, alcohols, aldehydes and ethers, etc., which will cause air pollution when discharged into the air. VOCs waste gas treatment equipment is a device that chemically reacts VOCs waste gas with prepared medicine to reduce the harmful components in the waste gas. During use, the problem of poor waste gas treatment effect often occurs.
