| titleOfInvention | The method of sulfate radical in the removal potassium chloride salt water system of environmental protection and economy |
| abstract | The invention provides the method for sulfate radical in a kind of removal potassium chloride salt water system of environmental protection and economy, comprise the following steps：(1) by potassium chloride salt solution A, by nanofiltration film unit, nanofiltration concentrated vitriol root obtains richness salt made from earth containing a comparatively high percentage of sodium chloride water B and poor salt made from earth containing a comparatively high percentage of sodium chloride water C；(2) rich salt made from earth containing a comparatively high percentage of sodium chloride water B is sent into gas-liquid-solid reaction member, is reacted with refining agent D calcium chloride solutions, obtain calcium sulfate and potassium chloride pasty material E；Described refining agent D is aqua calcis D1, or calcium chloride solution D3；(3) calcium sulfate and potassium chloride pasty material E that will react generation send into solid-liquid separation unit, and in the light salt brine G, described rich salt made from earth containing a comparatively high percentage of sodium chloride water A that obtain calcium sulfate wet feed F and low potassium sulfate, the clearance of potassium sulfate has reached more than 80%；The present invention has accomplished twice laid and emission reduction, and the calcium sulphate dihydrate that system is produced has carried out deep processing and comprehensive utilization, obtains can be used for the former useful products of the industries such as construction material, industrial chemicals, medicine. |
