专利汇可以提供Treatment of bittern by ionic salt preparation wherein device preparing potassium sulfate from mixed potassium salt containing magnesium chloride is combined with multiple effect evaporator and operated专利检索，专利查询，专利分析的服务。并且PURPOSE: To convert potassium chloride into potassium sulfate more effective as a fertilizer and to utilize it more efficiently, by combining a production apparatus for potassium sulfate from a potassium salt containing magnesium chloride with a multiple effect evaporator, operating them.
CONSTITUTION: A magnesium sulfate solution and a potassium salt containing magnesium chloride formed separately are added to the first reaction tank 5 of potassium sulfate, and reacted to give the bittern of potassium sulfate 9. The separated solution is stored in the mother liquor tank 10. The intermediate product 9 of first potassium sulfate and the regenerated potassium chloride obtained by the device 1 for regenerating potassium chloride are added to the reaction tank 5' of secondary potassium sulfate, water is further added to it, and they are stirred, potassium sulfate is formed, and sent to the centrifugal separator 6 to give the product 11 of potassium sulfate. The separated mother liquor having prepared the gypsum product 14 is stored in the tank 15 for bittern from which calcium is removed, the bittern freed from calcium is sent to the triple effect vacuum evaporator 18 in parallel by the pump 16, evaporated under reduced pressure, a mixed solution containing potassium is collected, and dehydrated by the centrifugal separator 21, to give a product.
