酸碱废气治理

 

酸碱废气会在电镀车间、制药厂等生产过程中产生,而且大多是无组织排放的废气。
 

处理方案:
在车间将无组织排放的废气首先经过收集罩收集后,废气经过引风机作用下,引入含酸(碱)的洗涤塔吸收中和,使含酸(碱)废气中和后达标排放。
 

处理方法:
酸(碱)废气由风管引出后,进入废气净化塔(逆流式洗涤塔)进行净化处理,净化塔内装填有一定的填料,这样可以使废气和吸收液充分接触,从塔上流下来的水再通过水泵提升到塔顶,不断循环利用,循环液在达到一定浓度后再排向污水处理系统统一排放。

设备性能特点:
 
工艺简单,管理、操作方便简洁;
 压降低,操作弹性大,具有良好的除雾性能;
 过滤废气效果好,去除率可达99%;
 The acid and alkali waste gas will be produced in the production process such as electroplating workshop, pharmaceutical factory, and most of them are non - organization exhaust gas.
Treatment programme:
In the workshop, the waste gas from the no - tissue emission is first collected through the collection cover, and the waste gas is absorbed by the induced draft fan scrubber to absorb and neutralize the acid ( alkali ) waste gas and the discharge standard after the exhaust gas passes through the collector.
Processing method:
After the acid ( alkali ) exhaust gas is drawn from the air duct, it enters the waste gas purification tower ( countercurrent washing tower ) for purification treatment, the filling with a certain filler in the purification tower, so that the exhaust gas and the absorption liquid are fully contacted, the water from the upstream of the tower can be raised to the top of the tower through the water pump, and the circulating liquid will be discharged to the sewage treatment system uniformly after reaching a certain concentration.
Performance characteristics of equipment:
The process is simple, management and operation is simple and convenient.
The pressure drop, the operation flexibility is large, has good demist performance;
The filtering effect is good and the removal rate is up to 99 %.
