The plate heat exchanger is a detachable heat exchange device composed of a plurality of corrugated heat transfer plates and pressed at a certain interval by rubber gaskets. When the plates are assembled, two sets of alternately arranged plates and are fixed with adhesives to seal the rubber sealing strips. The effect is to prevent fluid leakage and form a narrow mesh-shaped flow path heat exchange plate between the two plates. The corrugated shape increases the area and rigidity of the heat exchange plate and enables the fluid to form a turbulent flow at a low flow rate to achieve enhanced heat transfer.
The reasons for the blockage of the plate heat exchanger are various, involving construction, daily operation and maintenance, and the characteristics of the equipment itself. Therefore, in the process of using the plate heat exchanger, the construction and maintenance management and daily operation management should be carried out, and the filtering equipment should be optimized. In the aspect of plate heat exchanger cleaning, the online cleaning method is adopted, because the whole cleaning process has no damage to the equipment, effectively avoiding the problems of aging of the rubber pad caused by frequent disassembly and assembly of the heat exchanger, prolonging the service life, and ensuring the equipment after cleaning. Safe and effective, long-term operation, resulting in a significant reduction in heating system maintenance costs.
