一种VOC回收再处理装置
本技术涉及回收处理领域,具体为一种VOC回收再处理装置。
技术介绍
继SO2、NOX和氟里昂后,挥发性有机化合物VOC的污染成为世界各国关注的又一焦点,VOC是挥发性有机化合物(volatileorganiccompounds)的英文缩写。大多数VOC有毒、有恶臭、易燃易爆、可破坏臭氧层,不仅危害人的生命,还污染环境,易造成事故;会使人患积累性的呼吸道疾病,在高浓度突然作用下,有时会造成急性中毒,甚至死亡;都易燃易爆,在高浓度排放时易酿成火灾和爆炸。所以,VOC已成为世界性的公害。在现有工艺下,炭黑生产的主要原材料为煤焦油,炭黑车间油库区的规模一般有储油槽10个,工艺油槽10个,卸油池7个,总储存量约为2万立方米。原储油槽及工艺油槽顶部均设有呼吸口,卸油池在卸油过程中也为敞开式卸放,储存及卸放过程中都会有大量的油烟气外泄,不仅污染环境,还影响作业人员的身体健康。
技术实现思路
在现有技术中,原有的烟气装置是在油槽顶部加装一蝶阀,然后利用管道将储油槽、工艺油槽全部连接起来,使得油槽内部的油烟气互通,然后再经过一台离心风机作用,使得油烟气先经过静 ...
