导读:北京一汽车厂涂装车间废气包含油漆有机溶剂和涂膜烘干时的分解物,这些挥发性有机物对人的健康危害非常大,并且有恶臭气味,而且,这些危害物质的排出量会因使用涂料品种、使用量、使用条件等的变化而有差异,严重影响生产和作业环境。涂装车间废气主要发生源为喷漆室、晾干室和烘干室三者的排气,其中喷漆室的排气量最大,烘干室的排气浓度最大。

废气处理工艺

根据客户提供的数据及我公司现场勘查的车间工况,我们设计了一套4000Nm?/h风量的废气处理装置,具体工艺为:收集混合废气,然后通过管道进入干式过滤器除水除雾,再经过除尘器出去废气中的粉尘颗粒,然后通过活性炭吸附广西快3脱附装置进行废气浓缩,接入RCO催化燃烧设备进行燃烧,产生无毒无害气体达标排放,并将余热回收循环利用。
