Background In the chemical production process, the sodium acetate crystallization reaction kettle is a key device for sodium acetate crystallization reaction. In the crystallization reaction process of sodium acetate, scaling and layering phenomena are extremely easy to occur in a reaction kettle due to factors such as concentration change, temperature difference and characteristics of the solution. The scaling problem is mainly because during crystallization, as the solute is separated out and the crystals grow, part of the crystals are easily attached to the inner wall of the reaction kettle and gradually accumulate to form a hard scale layer. These scale layers not only can influence the heat transfer efficiency of reation kettle for temperature distribution is inhomogeneous in the reation kettle, thereby influences the reaction, still can increase the washing degree of difficulty and maintenance cost, shortens reation kettle's life. Delamination is caused by density difference, solubility change and uneven stirring in the reaction process of different components in the solution.
