摘要
[目的]大型船舶制造涂装废气成分复杂、污染物浓度高、排放风量大,同时含有漆雾、粉尘和挥发性有机物(VOCs).[方法]根据大型船舶制造涂装废气的排放特征,提出了一套"分级分质漆雾净化 + 沸石分子筛转筒 + 蓄热式热力氧化"的组合式治理工艺,分别阐述了各主要部分的设计原理、结构组成、关键参数和工程应用.[结果]该工艺可实现涂装废气中污染物的高效分离净化,废气在处理后能连续稳定地达到排放标准.[结论]单一处理方法无法实现大型船舶制造涂装废气的有效治理,经济高效的组合工艺和装备可有效降低处理成本,提高治理效率.
Abstract
[Introduction]The exhaust gas from paining process during large ship manufacturing features high contaminant concentration,complex composition,and large volume,and contains paint fog,dust,and volatile organic compounds(VOCs).[Method]The design principle,structure,key parameters,and engineering application of a treatment process comprising a gradient paint mist purifier,a zeolite molecular sieve rotator,and a regenerative thermal oxidizer were described.[Result]The process can achieve efficient purification of contaminants,and the exhaust gas can continuously and stably meet the emission standard after treatment.[Conclusion]A single treatment method cannot achieve effective treatment of painting exhaust gas from large ship manufacturing.The combined process and equipment can effectively reduce the running cost and improve the treatment efficiency.
