Application of plate heat exchanger

Autor:

Reasonable selection of heat exchange area is the key to procurement. When choosing a heat exchanger, first of all, it is necessary to select the required flow rate according to the process requirements, the viscosity of the material and the liquid, and the heat exchange temperature difference. Excessive flow results in waste, and the flow channel is easy to block. If it is too small, it will affect the use, increase the non-fermentation time, and cause unfavorable phenomena such as damage to the deflector due to excessive pressure. Therefore, the selection should be scientifically selected according to the working conditions.

The plate thickness of the plate heat exchanger is only 0.6~0.8mm, and the thickness of the heat exchange tube of the shell and tube heat exchanger is 2.0~2.5mm; the shell of the shell and tube heat exchanger is heavier than the layout of the plate heat exchanger. many. Under the condition of completing the same heat exchange task, the heat exchange area required by the plate heat exchanger is smaller than that of the shell and tube heat exchanger.
