Ⅰ. Overview and Treatment Methods of Packaging Printing Waste Gas Treatment Equipment
A large amount of organic waste gas is generated during the ink drying and volatilization process in the packaging printing industry. The waste gas contains high-concentration harmful benzene series such as benzene, toluene and xylene with significant hazards. Direct discharge will seriously pollute the surrounding atmospheric environment and damage the physical health of operators and nearby residents. To help printing enterprises realize compliant production, Zhonghuan Lvzhou Environmental Protection launches dedicated packaging printing waste gas treatment equipment adopting the combined process of UV photolysis + activated carbon adsorption. It is suitable for paper printing, plastic printing and other printing scenarios to achieve efficient gas purification and standard emission.

Ⅲ. In-depth Analysis of Core Treatment Process
1. UV Photolysis Equipment
As the core pre-treatment unit, UV photolysis equipment realizes efficient decomposition and oxidation of organic waste gas through the synergistic effect of high-energy ultraviolet beams and ozone. High-energy UV beams accurately destroy the molecular structure of volatile organic compounds such as benzene, toluene and xylene and split them into low-molecular compounds. Meanwhile, ozone further participates in oxidation reaction and converts cracked pollutants into non-toxic water and carbon dioxide. The process reduces the concentration and hazard of organic waste gas fundamentally and lays a solid foundation for subsequent adsorption treatment.
2. Activated Carbon Adsorption Tower
The waste gas treated by UV photolysis enters the activated carbon adsorption tower for deep purification. High-performance granular activated carbon is adopted with a specific surface area ranging from 500 to 1500m²/g. Its developed porous structure provides strong surface activity and adsorption capacity, which is highly applicable to the characteristics of large air volume and low-concentration organic waste gas in the printing industry. When waste gas flows through the adsorption bed, residual organic gas is firmly adsorbed by the active surface of activated carbon, ensuring the cleanliness of final discharged gas meets environmental protection standards.
Strict Compliance: Clear and Controllable Emission Indicators
Ⅳ. Core Advantages of Packaging Printing Waste Gas Treatment Equipment
1. High purification efficiency: The combined effect of UV photolysis and activated carbon adsorption achieves an overall purification efficiency of over 90% for printing waste gas, making all pollutant emission indexes far better than standard requirements.
