Description

Secondary condensation assembly for evaporator

Technical Field

The utility model relates to an evaporimeter technical field, concretely relates to second grade condensation subassembly for evaporimeter.

Background

The evaporator is an important part in four major refrigeration parts, and low-temperature condensed liquid passes through the evaporator to exchange heat with external air, gasifies and absorbs heat, and achieves the refrigeration effect. The evaporator mainly comprises a heating chamber and an evaporation chamber. The heating chamber provides heat required by evaporation to the liquid to promote boiling and vaporization of the liquid; the evaporation chamber makes the gas phase and the liquid phase completely separated. In industrial production, a large amount of flash steam can be generated when condensed water in the tower kettle of the rectifying tower is discharged, and if the condensed water is directly discharged, energy and materials are wasted.

The evaporator is divided into 3 types of normal pressure, pressurization and depressurization according to the operation pressure. The method comprises the following steps according to the motion state of the solution in the evaporator: (ii) a circulation type. The boiling solution passes the heating surface in the heating chamber multiple times, such as central circulation tube, suspended basket, external heat, lien and forced circulation. ② a one-way type. The boiling solution passes through the heating surface in the heating chamber once without circulating, and the concentrated solution is discharged, such as rising film type, falling film type, stirring film type, centrifugal film type and the like. ③ direct contact type. The heating medium is in direct contact with the solution for heat transfer, such as a submerged combustion evaporator. In the operation process of the evaporation device, a large amount of heating steam is consumed, and in order to save the heating steam, a multi-effect evaporation device and a steam recompression evaporator can be adopted. The evaporator is widely used in chemical industry, light industry and other departments.
