Improvement of control method for acid mist volatilization in pickling tank
Hydrochloric acid mist in pickling tank has volatilization and overflow problem,and pickling tank is improved.Test was carried out by automatically adjusting suction motor frequency and valve opening,designing H-shaped cavity and air curtain,and setting pickling tank rear baffle.After improvement,when cover plate is closed,mass concentration of acid mist around tank is 0.055 mg/m3,and air absorption effect of acid mist is increased by 95.3％,When cover plate is open,acid mist concentration around tank is 0.164 mg/m3,and air absorption effect of acid mist is increased by 97.9％,which meets allowable standard of salt mist concentration in workplace air.
