摘　　要：针对原废气处理系统的不足,利用负压抽吸引流物理吸收和化学吸收共同作用原理,改进了废气吸收装置,用吸收剂循环吸收和降温相结合的工艺,应用于500 t/a光引发剂生产装置的氯化氢及溴化氢废气回收上,氯化氢回收率97.5%以上、盐酸质量分数达22%,完全满足生产中后处理工序的要求;溴化氢回收率98%以上,氢溴酸质量分数可达40%。In terms of weakness of old waste gas treatment system, the paper innovates waste gas absorption device by means of interaction of. negative pressure aspiration drainage physical absorption and chemical absorption. With the technology of absorbent circulating absorption and cooling, it is applied to waste gas recovery of hydrogen chloride and hydrogen bromide of 500t/a photoinitiator manufacturing device. The recovery of hydrogen chloride is over 97.5%, fraction of hydrochloride quality reaches 22%, which satisfies the need of after - treatment process. The recovery of hydrogen bromide is over 98%, fraction of hydrobromic acid quality is 22%.
