  5.1 Overview:

   Evaporator is a very important part of the four major components of refrigeration, low-temperature condensing gas through the evaporator, and the outside air for thermal exchange, liquefy heat absorption, to achieve the effect of refrigeration.

5.2 Structure:    

   Mainly by the heating chamber and evaporation chamber consists of two parts. The heating chamber provides the heat needed for evaporation to the liquid, and induces the liquid to boil and vaporize; the evaporation

   Room so that the gas-liquid two phases are completely separated from the vapor produced in the heating room with a large number of liquid foam, to a larger space after the evaporation room, these liquids by self

  The role of their own cohesion or defoamer, etc. can be separated from the vapor. Usually the defoamer is located in the top of the evaporation chamber.

5.3 The Characteristics of Operation:

  Engineering, evaporation process only separates part of the solvent from the solution, and the solute still remains in the solution, therefore, evaporation operation that is a make the solution

  The separation process of volatile solvent and non-volatile solute in the solution. Because the vaporization rate of solvent depends on the heat transfer rate, so the evaporation operation is a heat transfer process.

  Heat transfer process, evaporation equipment for heat transfer equipment, however, evaporation operation and general heat transfer process comparison, there are the following characteristics:

1. Solution boiling point rises

  Because the solution contains non-volatile solute, therefore, at the same temperature, the vapor pressure of the solution is smaller than that of the pure solvent, that is to say, at the same

  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.

1. Material and process characteristics

  In the process of concentration, solutes or impurities are often deposited on the heating surface, precipitating crystals and forming a scale layer, which affects heat transfer; some solutes are thermally   

  Some solutes are heat-sensitive, easy to deteriorate at high temperatures for too long a stay; some materials have greater corrosiveness or higher viscosity, etc.

1. Energy recovery

  The evaporation process is a solvent vaporization process, and because the latent heat of solvent vaporization is large, the evaporation process is a large energy consumption unit operation. Therefore, energy saving Energy saving is an important issue that should be considered for evaporation operation.
