5. Finned evaporator: finned multi-stage automatic load capacity adjustment;

5.1 Overview:

The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed gas passes through the evaporator to exchange heat with the outside air, liquefy and absorb heat, and achieve the effect of refrigeration.

5.2 Structure:

It is mainly composed of heating chamber and evaporation chamber. The heating chamber provides the liquid with the heat required for vaporization, and promotes the liquid to boil and vaporize;

The hair chamber completely separates the two phases of gas and liquid. The steam generated in the heating chamber contains a large amount of liquid foam. After reaching the evaporation chamber with a larger space, these liquids can be separated from the steam by the action of self-condensation or a demister. Usually the demister is located at the top of the evaporation chamber.

5.3 Features of operation:

In engineering, the evaporation process only separates part of the solvent from the solution, while the solute remains in the solution. Therefore, the evaporation operation is a process of separating the volatile solvent and the non-volatile solute in the solution. Since the evaporation rate of the solvent depends on the heat transfer rate, the evaporation operation is a heat transfer process, and the evaporation equipment is a heat transfer equipment. However, compared with the general heat transfer process, the evaporation operation has the following characteristics:

A. The boiling point of the solution increases:

Since the solution contains nonvolatile solutes, at the same temperature, the vapor pressure of the solution is smaller than that of the pure solvent, that is,

Under the same pressure, the boiling point of the solution is higher than that of the pure solvent, and the higher the concentration of the solution, the more significant this effect is.

B. Material and process characteristics:

During the concentration process of materials, solutes or impurities often deposit and crystallize on the heating surface to form a scale layer, which affects heat transfer;

Quality is heat-sensitive, and it is easy to deteriorate if it stays at high temperature for too long; some materials are more corrosive or have higher viscosity and so on.

C. Energy recovery:

The evaporation process is a solvent vaporization process. Since the latent heat of solvent vaporization is large, the evaporation process is a unit operation with large energy consumption. therefore,

Energy saving is an important issue that should be considered in evaporation operations.

6. Other accessories: Danish filter drier, Japan Saginomiya solenoid valve
