High-viscosity liquids, heat exchanger selection issues
Thread Content
In the case of liquid-liquid heat exchange with high viscosity, the temperature difference between the liquids is not very large; however, the pressure loss in the plate heat exchanger is high, which results in high pressure in the grinder ahead of the heat exchanger. This causes the seal of the grinder to fail quickly. Is there any solution to this problem?
Why use plate heat exchangers and invite trouble for ourselves?
Why not consider other types of heat exchangers? Tube heat exchanger ； Spiral plate fin condenser (single-hole, multi-hole) ； What about the spiral-type condenser?
Shell-and-tube heat exchangers are often used for high-viscosity fluids
The tight gaps in plate heat exchangers are certainly not suitable for liquids with high viscosity like yours; the pressure in front of the plates is high, which can lead to clogging, and the heat exchange efficiency is poor as well. For your case, you should choose a shell-and-tube heat exchanger.
Use a shell-and-tube heat exchanger; let the medium with high viscosity flow through the shell side
A shell-and-tube heat exchanger can be considered.
It depends on how high the viscosity is; generally, shell-and-tube heat exchange is used, while stirred-tank heat exchange is employed when the viscosity is particularly high
Generally, for shell-and-tube types, those with high viscosity flow in the shell side
