An organic waste gas treatment device is a dry waste gas purification unit using activated carbon to purify organic waste gases, consisting of a housing and an adsorption unit. It is combined with pipeline fans to form a purification system, primarily utilizing activated carbon to adsorb organic waste gas molecules, separating them from harmless substances, thereby achieving air purification. It is widely applicable for treating large-volume low-concentration organic waste gases containing benzene, phenols, esters, alcohols, aldehydes, ketones, ethers, etc. It is extensively used in the purification of organic waste gases in paint spraying and brushing workshops in industries such as electronics, chemicals, light industry, rubber, machinery, ships, automobiles, and petroleum. It can also be used in production lines for shoe adhesives, chemical plastics, ink printing, cables, insulated wire, and more.
