粘胶工艺废气处理与溶剂回收

依据GB16297—1996 大气污染物综合排放标准，对各类粘胶过程产生的甲苯、二甲苯和非甲烷总烃等的排放量要达到限值要求。很多制造业中涉及粘胶工艺，如制鞋、制特种衣物等。溶剂胶具有制造简单、使用方便、粘合强度高等特点，深受企业欢迎。然而，它含有大量的有害挥发性溶剂，在粘胶工艺废气中的有机气体主要来自溶剂和稀释剂，有机溶剂在操作过程中，在粘附的表面会缓慢挥发。另一方面，在加热固化过程中也将全部释放形成有机废气。

The Treatment of Waste Gas from Viscose Process and Organic Solvent Recovery

Modified active carbon adsorption, water vapor elution and refrigeration were used to treat waste gas from viscose process, and recovery the organic solvent. The process of treatment and parameter were discussed here. The data illuminate that the organic solvent concentration of outlet gas was less than 100mg/m3. while that of inlet was between 1200-1800mg/m3.
