| titleOfInvention | The purifying plant of high yield super clean, high purified hydrofluoric acid |
| abstract | The utility model discloses the purifying plants of high yield super clean, high purified hydrofluoric acid, belong to purifying plant field, including raw material tank, the first oxidation processes device, first filter, the second oxidation processes device, the second filter, preheater, rectifying column, condenser, absorption tower, microporous membrane filters and finished product storage tank；The bottom side of condenser is equipped with cooling water tank, and the top on absorption tower is equipped with tail gas absorber；The first cooling water pipe being vertically arranged, the cold pipe of acid, the second cooling water pipe are equipped in condenser.The purifying plant of the high yield super clean, high purified hydrofluoric acid of the utility model carries out effective temperature-reducing by hydrofluoric acid of the condenser to purification production, and cooling effect is obvious, avoids impacting stainless steel tube, extends service life of equipment, reduces maintenance cost；By the way that tail gas absorber is arranged at the top of absorption tower, the hydrofluoric acid gas that effective recovery section is not fully absorbed reduces the pollution to environment, meets environmental requirements. |
