Description of products

Mainly consists of two parts, the heating chamber and the evaporation chamber. Heating chamber to provide liquid calories needed to evaporate makes liquid boiling vaporization. Evaporation chamber quickly two-phase separation completely. Steam generated by the heating chamber with a large number of liquid foam, to a bigger space after the evaporation chamber, the liquid condensation of lend itself or the role of the defoaming and etc. Usually defoaming device located in the top of the evaporation chamber.

The evaporator in accordance with the operating pressure points and atmospheric pressure, compression and decompression. According to the solution in the evaporator movement status points are: 1) circular, boiling solution many times by heating surface in the heating chamber, such as the central circulation pipe, hanging baskets, external heated, levin and controlled circulation etc. 2) single type, boiling solution of a surface by heat in the heating chamber, not as a curcular flow, shall discharge concentrate, such as climbing film type, falling film type, mixing membrane type and centrifugal fim type etc. 3) direct contact type, the heating medium and the solution of direct contact heat transfer, such as the submerged combustion evaporator. Evaporation device in the process of operation, consumes a large amount of heating steam, to save on heating steam, can use multi-effect evaporation device and steam compression evaporator. The evaporator is widely used in chemical industry, light industry and other departments.

Evaporation is to use the heating method, does not contain volatile solute to solution is heated to boiling condition, the solvent evaporation and has been removed, thus improve the solute concentration of the solvent unit operation. Industrial production in the application of evaporation operation has the following situations:

a. Condense dilute solution for making products directly or concentrated solution to deal with, such as the cooling crystallization for making solid products, such as electrolytic caustic soda concentration, sugar concentration of aqueous solution and all kinds of fruit juice concentrate etc.

b.At the same time concentrated solution and recovered solvents, such as the enrichment of benzene, benzene solution of organophosphorus pesticide in the production of traditional Chinese medicine alcohol leaching liquid evaporation etc.

c.In order to obtain pure solvents, such as desalination etc.

In a word, in the chemical industry, food industry, pharmaceutical industry, such as evaporation operation is widely used.
