摘　　要：本文主要介绍了某公司在采用干法再生回收利用废旧包装铁桶过程中所产生废气的处理设计案例。该种废气与常见的印刷生产、涂料生产、喷漆后固化等过程产生的废气有较大不同,其成分更加复杂,因而处理难度更大。通过分析各种处理工艺的适用范围、优缺点、运行成本等,最终确定先经过各种预处理后,再采用分子筛吸附浓缩+CO再生处理。经该工艺设施处理后的排气中VOC、颗粒物等主要污染指标均达到设计要求,满足广东省地方标准《家具制造行业挥发性有机化合物排放标准》(DB44/816-2010)的排放要求。This paper mainly introduces a design case of waste gas treatment in the process of recycling waste packaging barrels by dry method in a company.The exhaust gas is quite different from the exhaust gas generated in the common printing production,coating production,postpainting curing and other processes,and the exhaust gas composition is more complex and the treatment is more difficult.By analyzing the application scope,advantages and disadvantages,operation cost of various treatment processes,it is finally determined that after various pretreatment,molecular sieve adsorption concentration plus CO regeneration treatment is adopted.After treatment by the process facilities,the main pollution indicators such as exhaust VOC and particulate matter meet the design requirements and meet the emission requirements of the local standard of Guangdong Province,“Emission Standard for Volatile Limited Compounds in Furniture Manufacturing Industry”(DB 44/816-2010).
