Description

Technical Field

[0001] The utility model relates to the technical field of purification, in particular to a corrosion inhibitor high-efficiency purification device. Background Art

[0002] The main function of corrosion inhibitors is to inhibit or slow down the corrosion efficiency of metals in corrosive media. If the corrosion inhibitor contains impurities, these impurities may interfere with the interaction between the corrosion inhibitor and the metal surface and reduce the protective effect of the corrosion inhibitor. Therefore, the corrosion inhibitor needs to be purified. One of the methods of purifying corrosion inhibitors is to purify them by recrystallization. The corrosion inhibitor recrystallization is added to a stirring tank, and a solvent in which the corrosion inhibitor is dissolved is added, and the mixture is heated and stirred. After the heating and stirring are completed, the stirring tank is cooled to precipitate the corrosion inhibitor crystals, and finally dried. However, during the heating and stirring process, liquid remains on the inner wall of the stirring tank. During the cooling process, crystals will precipitate from the residual liquid on the inner wall, resulting in reduced purification efficiency of the corrosion inhibitor. Therefore, there is an urgent need for an efficient purification device for corrosion inhibitors that can solve the problem of residual crystals on the inner wall of the stirring tank during the recrystallization process, thereby improving the purification efficiency of the corrosion inhibitor.
