Research of Self-cleaning Technique of Crystallizing Salt Adhered to the wall of Heating Tube in Salt Evaporator

The importance of the cost of energy consumption of salt crystals adhered to inside wall of heating tube of evaporator is discussed in this paper. The existing self-cleaning technology is briefly appraised. The self-cleaning technology with rotational twisted strips is stressed. Its construction principle is that rotational twisted strips are driven by circulating flow energy of evaporating solution in the tube to rotate and clean salt crystal. The cleaning ability is tested by simulation experiments according to the principle of crystallization dynamics. The experiment results showed that self-cleaning technology can meet the demand of salt crystal self-cleaning and the aim of long-term continuous production and be applied in evaporation production generally and has remarkable economics superiority.
