[0003] Single-effect evaporator is a common evaporation equipment, which is used to concentrate or separate the solute in the liquid. By heating the liquid, the solvent in it evaporates, so that the concentration of the solute in the liquid gradually increases. When the liquid is in the evaporation chamber, the liquid may have uneven temperature. The heating surface can only heat the part of the liquid it contacts, while the temperature of other parts may be lower, resulting in uneven heating of the liquid, affecting the evaporation efficiency and concentration effect, resulting in lower concentration in other areas, affecting the concentration effect and product quality. After the liquid is heated, solid residues or other solid impurities are generated in the evaporation chamber. These solid residues may be deposited or accumulated inside the evaporator, causing blockage and poor operation of the equipment. The product contains impurities, which reduces the purity and quality of the product, thereby affecting subsequent production or use. Utility Model Content
