摘要:

针对家具制造企业涂装过程产生的含挥发性有机物(VOCs)废气,提出光催化-喷淋吸收耦合技术处理此类废气.该方法在传统处理技术基础上利用催化剂的光催化活性,提高行业典型VOCs处理效率的同时解决现有涂装废气治理技术存在的运行费用高、降解产物不彻底等问题.在前期小试基础上,研发出1套设计气量为1 000 m3/h的光催化喷淋吸收耦合净化装置,并对本装置降解行业典型挥发性有机物的效果和工程应用可行性进行研究.结果表明,该装置处理甲苯、乙酸乙酯的降解效率分别达到52.82%、63.99%.相关运行费用与现有工艺相比具有一定竞争力.因此,该技术可为解决家具制造行业涂装废气污染问题提供新的途径.

Abstract:
Photocatalytic-absorption technique was applied to decompose the volatile organic compounds (VOCs) from painting process in furniture manufacturing enterprises. The photocatalytic activity of the catalyst was utilized to improve the degradation efficiency of the typical VOCs, while solving the problems of high running cost and incomplete degradation of the existing exhaust gas treatment technology. A photocatalytic-absorption configuration which is capable of treating painting exhaust gas at 1 000 m3/h was developed on basis of laboratory test. The effect of typical VOCs degradation and the feasibility of engineering application were also investigated.The removal efficiency of toluene and ethyl acetate are52.82% and 63.99%, respectively. Operating costs of the technology have comparative competitiveness compared with other current operating process. This process provides a newly efficient alternative to the conventional methods for the removal of VOCs.
