Abstract
With the acceleration of industrialization, the emission of chemical waste gases has become a significant source of atmospheric pollution, and their complex compositions and high toxicity pose serious threats to ecological environments and human health. To address this challenge, this study aims to develop an efficient, economical, and easy-to-maintain purification device for chemical waste gases to meet increasingly stringent environmental protection requirements. Based on the coupling technology of adsorption and catalytic oxidation, a multi-stage purification system was designed, and the removal efficiency of organic pollutants in waste gases was significantly improved through optimized selection and structural design of adsorbent materials. Meanwhile, a novel catalyst was introduced in combination with heat recovery technology, achieving deep purification under low-energy-consumption conditions. Experimental results indicate that the removal rate of volatile organic compounds (VOCs) in typical chemical waste gases can reach over 95%, demonstrating excellent stability and adaptability under continuous operation. Additionally, an innovative online monitoring module was integrated to provide real-time feedback on purification performance and adjust operational parameters, further enhancing system performance. The primary contribution of this study lies in proposing a waste gas treatment solution that combines high efficiency with cost-effectiveness, providing technical support for the green transformation of the chemical industry and serving as a reference example for waste gas management in similar industrial scenarios..
