| titleOfInvention | Acid-washing waste acid processing unit |
| abstract | The utility model is related to a kind of acid-washing waste acid processing units, including cold boiler, pipeline connection cold boiler and cool down the condenser of boil-off gas, the preceding road of cold boiler is equipped with preheater, the diluted acid collecting tank of condensator outlet end pipe road connection storage dilute hydrochloric acid, the cold boiler bottom discharge mouth is communicated with the dope kettle of the heating evaporation again of the concentrated acid liquid after evaporation, the crystallisation by cooling kettle of frerrous chloride in a pair of of crystallization extraction concentrated acid liquid of dope kettle pipeline connection, pipeline Xun Huan connection between the crystallisation by cooling kettle, the buffer bin of storage frerrous chloride crystal is arranged below in crystallisation by cooling kettle.The utility model ideal treatment effect, pass through the separated method of circulation crystallization, unsaturated solution after crystallization is separated with crystalline solid, then unsaturated solution is concentrated again postcooling crystallization, so as to efficiently separate the frerrous chloride in acid-washing waste acid, hydrogen chloride, and 20% or so hydrochloric acid return pickling line use is obtained, save spent acid processing cost. |
