Plate heat exchanger for, e.g. desalination of seawater, comprises compression-molded heat exchanger plates successively provided in plate package that encloses evaporation, separation, and condensation sections

摘要

A plate heat exchanger for treatment of a medium, comprises compression-molded heat exchanger plates (1), which are successively provided in a plate package and which form first plate interspaces (5) for the medium and second plate interspaces. The first and second plate interspaces are provided in an alternating order in the plate package. The plate package encloses an evaporation section, a separation section, and a condensation section provided in such a way that the evaporation, separation and condensation are permitted in each of the first interspaces. A plate heat exchanger for treatment of a medium comprises compression-molded heat exchanger plates, which are successively provided in a plate package and which form first plate interspaces for the medium and second plate interspaces. The first and second plate interspaces are provided in an alternating order in the plate package. The plate package encloses an evaporation section, a separation section, and a condensation section. The evaporation section permits evaporation of at least a part of the medium flowing through the first plate interspaces. The separation section separates non-evaporated liquid from the evaporated part of the medium. The condensation section condenses the evaporated part flowing through the first plate interspaces. The evaporation section, separation section and condensation section are provided in such a way that the evaporation, separation and condensation are permitted in each of the first interspaces.
