| titleOfInvention | A phosphoric acid purification and dearsenic device |
| abstract | The invention discloses a phosphoric acid purification and dearsenic device, comprising a dearsenic reaction tank, a tail gas washing system, a tail gas chimney, a pretreatment filtering system, an extraction system and a precision filtering system. Among them, the dearsenic reaction tank includes phosphoric acid inlet, sodium sulfide inlet, tail gas outlet, tail washing liquid inlet, and phosphoric acid outlet of the dearsenic reaction tank, and the tail gas washing system includes washing tail gas inlet, tail washing liquid outlet, washing tail gas outlet, and sodium hydroxide solution. At the inlet, the tail gas chimney is provided with a chimney tail gas inlet. The pretreatment filter system includes a pretreatment filter mixed acid inlet, a pretreatment filter residue outlet, and a pretreatment filter acid outlet. The extraction system includes an extraction phosphoric acid inlet, an extraction agent inlet, and a load solvent outlet. At the outlet of raffinate acid, the precision filtration system includes a casing, a filter element and a filter element separator, and the filtration separator divides the casing into a filtration primary liquid chamber and a filtration clear liquid chamber; the filter element is installed on the separator. The invention can effectively reduce the leakage risk of hydrogen sulfide. |
