How to treat waste gas in the plastic industry?
1, The hazards of industrial plastic waste gas
The exhaust gas generated during the production process of industrial plastic products has great harm, mainly due to the chemical composition and production process of plastic products:
Chemical hazards: Plastic products are made by polymerizing olefins containing chlorine or benzene rings, and antimony compounds need to be added as catalysts during the processing. Under certain conditions, benzene rings and chlorine elements in plastics will fall off the polymer chains, forming toxic substances. These substances pose great harm and cause serious harm to human health.
Environmental risk: The released toxic substances will be discharged into the environment, polluting the environment, water sources, and soil, causing long-term damage to the ecosystem.
2, Treatment plan for industrial plastic waste gas
1. The selection of governance technologies depends on different plastic product industries, and the composition of exhaust gases varies due to different production processes and raw materials. Therefore, targeted governance technologies must be adopted. Adsorption desorption concentration catalytic combustion equipment is currently the mainstream effective treatment solution.
2. Equipment working principle
Adsorption concentration: Using adsorbents (such as activated carbon) to adsorb organic waste gas from low concentration to high concentration, reducing the subsequent treatment volume.
Catalytic combustion: After being blown by hot air, the adsorbed organic waste gas is desorbed to form high concentration waste gas, which then enters the catalytic combustion chamber and is low-temperature oxidized and decomposed into carbon dioxide and water under the action of the catalyst.
