Design Features and Application Fields/Occasions of Detachable Plate Heat Exchangers

Release Time:

Jul 14,2022

The detachable plate heat exchanger is made of a number of corrugated metal sheets that are pressed and formed at certain intervals, sealed around by gaskets, and pressed by the frame and clamping bolts. The four corner holes of the plates and gaskets The distribution pipe and the collecting pipe of the fluid are formed, and at the same time, the hot and cold fluids are distributed reasonably freely, and the heat transfer is carried out through the plates to achieve the purpose of heat exchange. The frame is composed of a fixed pressing plate, a movable pressing plate, upper and lower guide rods and clamping bolts.
Design features of the detachable plate heat exchanger:
1. Energy saving: its heat transfer coefficient is 3000~9500kcal/m2?°C?h, which is 3~5 times higher than the thermal efficiency of shell and tube heat exchangers.
2. Compact structure: The plates of the plate heat exchanger are closely arranged. Compared with other types of heat exchangers, the plate heat exchanger occupies less floor space and space, and the plate heat exchanger with the same area for heat exchange is only the tube 1/5 of the shell heat exchanger.
3. Easy to clean and easy to disassemble: the plate heat exchanger is clamped by clamping bolts, so it is easy to disassemble and clean, and it can be opened and cleaned at any time.
4. Long service life: The plate heat exchanger is pressed by stainless steel or titanium alloy plates, which can resist various corrosive media.
5. Strong adaptability: The plate heat exchanger plate is an independent element, and the process can be increased or decreased at will according to the requirements, in various forms; it can be applied to various different process requirements.
6. No liquid leakage, the sealing groove of the plate heat exchanger is equipped with a liquid leakage channel, and various media will not be connected with each other. Even if there is leakage, the medium is always discharged outwards.
