The technology comprises the following steps: precooling the waste gas with the triplex counter flow heat exchanger which is installed on the waste gas intake pipe, then the waste gas flowing in clarifying tank which is in a cold trap connected with the liquid nitrogen compression refrigerating machine to remove the noxious gas, such as SO2. The technology needn't the acid and alkali, reduces the treatment cost and hasn't secondary pollution.
本发明针对现有技术中存在的需要消耗大量的酸碱等化学原料，处理成本高，并且伴随产生低值废弃物的二次污染等问题，提供这样一种工艺方法及装置：从硫酸厂出来的未经处理的废气，经过串连于废气输入管上的三级热交换器的逆向热交换而预冷后到达了净化池中，净化池置于一个冷阱中，而冷阱与液氮压缩制冷机相连通，使净化池温度可达到-180℃，到达净化池的毒害气体如SO 2 由于深冷作用而凝固落在池里，从而达到净化废气的目的。
The water extractor duct removes some moisture condensed after the air passed and cooled from the Secondary Heat Exchanger, using the centrifugal effect swirling the air through vanes to separate water particles from the air and sends the moisture to a water collector.
