The paint and coatings in the spraying workshop contain harmful substances to the human body, such as formaldehyde and benzene. Formaldehyde is a colorless, water-soluble, and strongly irritating gas that can be absorbed by the human body through the respiratory tract, causing long-term harm to the human body.

After inhaling formaldehyde, the human body does not have a significant reaction in a short period of time, but over time, it can easily lead to diseases such as nasopharyngeal carcinoma that can cause death. Its latency and concealment often make it difficult for people to detect it at the first time.

Paint, coatings, and adhesives contain a toxic liquid called benzene, which has a special aromatic aroma and is easily volatile. Long term inhalation of benzene can anesthetize the central nervous system, leading to a decrease in the body’s red and white blood cells as well as platelets, making it highly susceptible to anemia.

The organic waste gas generated by the spraying industry can be treated by activated carbon adsorption. First, use a fan to collect the exhaust gas into the activated carbon adsorption device, and then use the adsorption function of activated carbon to remove formaldehyde and benzene from the organic exhaust gas.

Activated carbon adsorption is suitable for the treatment of organic waste gases with low concentration and high air volume or high concentration intermittent emissions, and is widely used in industries such as electronics, metallurgy, petroleum, chemical, pharmaceutical, coating, food, furniture, rubber, printing, etc.
Compared to other waste gas treatment processes, activated carbon adsorption equipment has low investment costs, high treatment efficiency, no luminescence or heat generation, no open flames, and no safety hazards.
