在通用设备、机械制造行业中VOCs废气收集需要关注的6点

发布时间:2020.09.04    点击数: 71345

       通用设备、机械制造行业(大型钢构、造船厂钢构/海工配件等)VOCs 排放主要在调漆、涂装和干燥等工段,从车间功能来看,集中在喷漆房(包括底漆、面漆、清漆)、调漆房、干燥房。为减少无组织排放,最大限度的控制VOCs 排放量,需做好有机废气收集工作。那应该怎么做,应重点对照如下6点!

1)使用溶剂型涂料的喷漆房、干燥车间应严格密闭;对于流水线作业无法全封闭的情况,在进出口等敞开位置需设置风幕装置;换气风量根据车间大小确定,保证VOCs 废气捕集率不低于95%;

2)对于只能采用吸风罩收集的工序,排风罩设计应满足《排风罩的分类及技术条件》(GB/T 16758—2008)要求;

3)采用整体密闭的生产线,密闭区域内换风次数原则上不少于20次/ 小时;对于整体密闭换风的车间,车间换风次数原则上不少于8 次/小时;所有产生VOCs 的密闭空间应保持微负压;

4)喷漆室设计除满足安全通风外,任何湿式或干式喷漆室的控制风速应满足《涂装作业安全规程喷漆室安全技术规定》(GB 14444—2006)中下表的要求,如下表所示。当然,一切的前提还要满足GB-37822对控制点风速的要求。

5)收集系统能与生产设备同步启动,集气方向与污染气流运动方向一致,涂装工艺设计及废气收集应注意同时满足安全生产的相关规定,管路应有明显的颜色区分及走向标识。

6)废气收集系统材质应防腐防锈,定期维护,存在泄漏时需及时修复。
