| titleOfInvention | The recovery process device of ferrous chloride in acid washing rolled steel liquid |
| abstract | The invention provides ferrous chloride and the recovery process device of hydrochloric acid in a kind of acid washing rolled steel liquid, containing pickle preheater, multiple stage secondary preheater, steam heater, ejector condenser, cold acid return tank, multi-stage evaporator, solution cooler, mother liquor tank, filter.The raw material of pickle is by entering secondary preheating device after pickle preheater, a small amount of the most injected condenser of HCL acid vapor is condensed into cooling acid and enters cold acid return tank.Pickle enters vaporizer after being heated by steam device heating, and the HCL acid vapor wherein discharged flows out pipeline and flows out from the top of vaporizer, enters secondary preheating device；The solution of remaining chloride containing ferrous iron flows out from the bottom of vaporizer, it is introduced into solution cooler, separating out ferrous chloride crystal through separation filter again, remaining remaining mother solution enters mother liquor tank, and mother solution enters back into recovery cyclic process after mixing in the ratio of 3 10:1 with the raw material of pickle.Ferrous chloride in the mixed liquor of the present invention is in undersaturated condition all the time, solves the difficult problem blocked in preheater and process pipelines because of crystallization；Save energy resource consumption, decrease equipment investment. |
