酸雾吸收塔概述
喷(pen)淋式填料净(jing)化(hua)塔（酸雾(wu)(wu)(wu)吸收塔、废气(qi)(qi)(qi)吸收塔、尾气(qi)(qi)(qi)净(jing)化(hua)塔），广泛应用于各种(zhong)化(hua)工、电工电子(zi)、冶金(jin)、工业生产等(deng)多种(zhong)领域的气(qi)(qi)(qi)体净(jing)化(hua)工艺，处(chu)理的主要(yao)有害气(qi)(qi)(qi)体为硫酸雾(wu)(wu)(wu)、盐(yan)酸雾(wu)(wu)(wu)、铬酸雾(wu)(wu)(wu)、硝酸雾(wu)(wu)(wu)、磷酸雾(wu)(wu)(wu)、氢(qing)(qing)氟酸雾(wu)(wu)(wu)、氯化(hua)氢(qing)(qing)、氟化(hua)氢(qing)(qing)、硫 化(hua)氢(qing)(qing)、氰化(hua)氢(qing)(qing)等(deng)。本塔利用填料及气(qi)(qi)(qi)液(ye)交(jiao)换(huan)塔盘进行气(qi)(qi)(qi)液(ye)交(jiao)换(huan)，达到净(jing)化(hua)废气(qi)(qi)(qi)的目的。
工作原理
本(ben)装(zhuang)置采用氢氧化(hua)(hua)钠溶液(ye)为吸(xi)收(shou)中(zhong)(zhong)和液(ye)来净化(hua)(hua)废(fei)气(qi)(qi)。气(qi)(qi)体由离心通(tong)风机压入(ru)或吸(xi)入(ru)进(jin)风段，再向上流动，至第(di)(di)一级填料(liao)(liao)层(ceng)，与(yu)第(di)(di)一级喷(pen)(pen)(pen)嘴(zui)喷(pen)(pen)(pen)出的中(zhong)(zhong)和液(ye)接触反(fan)应。吸(xi)收(shou)后(hou)的废(fei)气(qi)(qi)继续向上流动至第(di)(di)二级填料(liao)(liao)层(ceng)，与(yu)第(di)(di)二级喷(pen)(pen)(pen)嘴(zui)喷(pen)(pen)(pen)出的中(zhong)(zhong)和液(ye)接触，再次发生中(zhong)(zhong)和反(fan)应，根据(ju)废(fei)气(qi)(qi)各项指标(biao)，还可以(yi)加(jia)装(zhuang)第(di)(di)三级填料(liao)(liao)及喷(pen)(pen)(pen)淋装(zhuang)置，净化(hua)(hua)达标(biao)后(hou)的气(qi)(qi)体通(tong)过除雾(wu)器排入(ru)大(da)气(qi)(qi)中(zhong)(zhong)。
