Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a condensation and evaporation dual-purpose plate heat exchanger. Background Art

[0002] The condensation and evaporation dual-purpose plate heat exchanger is a highly efficient device for heat transfer, combining the two functions of condensation and evaporation. It consists of a series of parallel plates, each of which has complex flow channels and channels for transferring heat energy. The condensation and evaporation dual-purpose plate heat exchanger can be used for both the condensation process and the evaporation process. In the condensation process, it can cool the gas or steam into a liquid state, and in the evaporation process, it converts the liquid into a gas or steam state.

[0003] Condensation and evaporation dual-purpose plate heat exchangers are widely used in many industrial fields. In the process of oil refining, crude oil is fractionated through a distillation tower to separate components in different boiling point ranges to obtain various petroleum products, including gasoline, diesel and kerosene.
