Reasonable selection of heat exchange area is the key to procurement.When choosing a heat exchanger, you must first select the required flow rate based on process requirements, material viscosity, heat exchange temperature difference, etc.Too large a flow rate will cause waste and the flow channel will be easily blocked. Too small a flow rate will affect the use and increase the non-fermentation time.It will also cause adverse phenomena such as damage to the guide plate due to excessive pressure. Therefore, when choosing, you should make a scientific purchase based on the working conditions.
The plate thickness of the plate heat exchanger is only 0.5~0.8mm, and the heat exchange tube thickness of the shell and tube heat exchanger is 2.0~2.5mm;The shell of a shell and tube heat exchanger is much heavier than that of a plate heat exchanger. When completing the same heat exchange mission, the heat exchange area required by a plate heat exchanger is smaller than that of a shell and tube heat exchanger.
Heat exchanger application range:
