Bittern and Repone K prepare the method for vitriolate of tartar

The present invention a kind ofly prepares the method for vitriolate of tartar with salt pan bittern and Repone K, and the raw material bittern transforms with Repone K and produces vitriolate of tartar, simultaneously by-product Industrial Salt and old halogen through pervaporation, cooling, flotation.Quality of potassium sulfate reaches import potash fertilizer index, and Industrial Salt is up to state standards, and old halogen can be used as the raw material of carrying bromine and producing magnesium chloride hexahydrate.The potassium rate of recovery of all processes reaches more than 95%, and 1 ton of vitriolate of tartar of every product needs about 20 tons of raw material bittern, 1.9 tons of by-product salt, 7.5 tons of old halogen.No any trash discharge in the technological process.If adopt this technology that domestic bittern chemical factory is transformed, will produce fairly obvious economic results in society.
