A method of inhibiting calcium sulfate scale formation in an evaporator

Abstract

The application discloses a method for inhibiting calcium sulfate from scaling in an evaporator, and belongs to the technical field of scale inhibition treatment. The method for inhibiting calcium sulfate from scaling in the evaporator comprises the following steps: preparing an ammonium ionic liquid additive; adding an NH4Cl solution into the ammonium ionic liquid additive, uniformly mixing, and obtaining an ammonium ionic liquid+NH4Cl stock solution; adding CaSO4.2H2O into the ammonium ionic liquid+NH4Cl stock solution to prepare a mixed solution, uniformly mixing the mixed solution, performing centrifugal treatment on the mixed solution, taking supernatant, and obtaining a solution. The method for inhibiting calcium sulfate from scaling in the evaporator can solve the problem that calcium sulfate is easy to scale in an ammonium chloride solution, thereby causing the evaporator to be blocked.
