催化氧化在VOCs和恶臭尾气处理上的工程实践

Engineering Practice of Catalytic Oxidation in VOCs and Malodor Tail Gas Treatment

目前我国对工业挥发性有机化合物(VOCs)的排放愈发严格和规范,对要排放的废气进行处理,排入大气的VOCs含量符合限值要求。本文论述了现阶段工业生产过程中VOCs废气治理现状以及终端处理的各种处理技术。针对生产装置生产过程中产生的废气组成以及排放特征,通过工艺路线的分析,选择催化氧化处理技术,建设废气处理装置。对在处理装置调试过程中出现的无脱水、催化剂积尘、排放不达标、催化剂再生以及系统积尘积液等问题进行了原因分析,采取了工程、工艺等整改措施,使得处理装置平稳运行,排放VOCs废气的去除效率82.5%~95.6%。处理后的废气达到排放标准要求。

According to the exhaust gas emission characteristics of the production plant,the catalytic oxidation treatment technology was selected after the process route analysis,and the waste gas treatment device was built.In the debugging process of the treatment device,the causes of problems such as no dehydration,catalyst dust accumulation,substandard discharge,catalyst regeneration and system dust accumulation were analyzed,and rectification measures such as engineering and process were taken to make the treatment device run smoothly,and the removal efficiency of VOCs exhaust gas was 82.5%~95.6%.The treated waste gas met the requirements of the emission standards.
