During the process of recycling waste plastic into granules, due to the differences in materials and molecular structures.A large amount of smoke and exhaust gases are produced, causing pollution to both humans and the environment. There are many common methods for removing smoke and odors from recycled granules, such as...Activated carbon adsorption, plasma treatment, UV photolysis, and catalytic combustion methods.

Activated carbon adsorption equipment is a common method for treating VOCs, particularly suitable for handling low-concentration VOCs. The activated carbon adsorption chamber is an effective and economical waste gas purification equipment for treating organic fumes, odor gases, malodorous gases, and foul odors. It features a wide pore distribution, well-developed micropores, and a rapid adsorption process, capable of吸附 substances of different molecular sizes. It is highly effective in adsorption and recovery of VOCs like benzene, ethyl acetate, and chloroform. Its non-polar and hydrophobic surface characteristics provide good selectivity for adsorbing non-polar substances. Moreover, activated carbon raw materials are inexpensive and abundant, the preparation process is simple, and it is easy to desorb and regenerate. Based on these factors, activated carbon is widely used as an adsorbent to treat low-concentration, high-volume VOCs with medium relative molecular mass (typically around 45-130).
