3.1 Technical Background
The current production of CCL is wet production, and the glue contains 30%~40% organic solvent. During the dipping and drying process of the substrate in the gluing machine, these solvents volatilize into the air, which has a great impact on the pollution of the environment. The waste gas containing a large amount of organic solvents is usually discharged directly or sent to the waste gas incinerator to burn it. In response to environmental protection requirements an...

2.1 Technical background
The exhaust gas emitted during the viscose fiber production process contains carbon disulfide and hydrogen sulfide. If it is directly discharged into the atmosphere, it will form acid rain and affect the quality of the local environment. This hazard has been increasingly recognized by people, and the treatment of exhaust gas is also increasing. It has been paid attention to in recent years, so that various waste gas treatment technologies have been developed in order...

1.1 Technical Background
The painting process is widely used in machinery, electrical equipment, household appliances, automobiles, ships, furniture and other industries. Spray paint exhaust gas is mainly composed of volatile solvents, thinner molecules and non-volatile paint mist molecules. Paints have complex solvent or thinner mixtures. Due to the small paint mist particles, high viscosity, and easy adhesion to the surface of substances, especially when activated carbon is used to absorb ...
