Background technology
Cold-rolling pickling production line in China's has hundreds of at present, but in the sector, either continuous pickling, plug-type
Pickling lines, its technique are all that acid solution first is heated into technological temperature to carry out recycle stream dynamic formula pickling by circulating pump again.
During this, substantial amounts of HCL gases will evaporate with vapor from hydrochloric acid so as to produce substantial amounts of acid mist, hydrochloric acid
Loss and the purified treatment of acid mist also just turn into two hang-ups of puzzlement pickling manufacturer.
Present most of manufacturers take carries out washing absorption using the mode of acid mist scrubbing tower to acid mist, after absorption
Acid solution is directly discharged to water treatment station, had so not only wasted acid solution and water resource simultaneously but also needs processing is largely useless containing diluted acid
Water, the production cost of Shi Ge pickling producer increase.It was verified that acid mist only by being difficult after acid mist scrubbing tower progress washing absorption
Reach discharging standards, very big pollution is caused to environment.According to practical application experience in recent years, we have devised one
Increase a set of tube-type graphite acid mist condenser before being enclosed on the acid mist reclaiming clean device that conventional manufacturer uses.
