Moreover, on the premise of ensuring the heat exchange capacity, it is possible to ensure the use of the plate type with a slightly wider flow channel, and avoid the use of the plate type with a narrow flow channel. With a wide flow channel, the flow rate through the flow channel of the plate heat exchanger will naturally decrease, thus the pressure loss will also continue to decrease.
With the wide application of plate heat exchanger in industry and the requirements of process system, plate heat exchanger, as a part of the process system, should have strict requirements for the pressure loss of its medium when the medium flows through the plate heat exchanger, so as to ensure the reliability of the subsequent process. Therefore, to save economic benefits, the inter-plate flow rate of plate heat exchanger is the main reason for pressure loss, and reducing the inter-plate flow rate can effectively reduce the pressure loss of plate heat exchanger, so how to reduce the flow rate between plate heat exchangers?
First of all, on the premise of not changing the original structure of the plate heat exchanger, reduce the flow of medium in the plate heat exchanger as much as possible. When the flow rate decreases, the flow rate will naturally decrease, but the medium type, temperature, flow rate and other parameters in the process system are usually specific values, so this method is not feasible.
Secondly, the number of plates in the plate heat exchanger increases, and the number of flow channels increases accordingly. The flow of each flow channel naturally decreases, so the pressure loss also decreases.
Moreover, on the premise of ensuring the heat exchange capacity, it is possible to ensure the use of the plate type with a slightly wider flow channel, and avoid the use of the plate type with a narrow flow channel. With a wide flow channel, the flow rate through the flow channel of the plate heat exchanger will naturally decrease, thus the pressure loss will also continue to decrease.
Therefore, the selection of plate heat exchanger should be personalized according to the actual situation of the process, rather than blindly based on the model and experience.
The above is the method for you to reduce the flow rate between plates of plate heat exchanger. I hope it will help you!
