Causes And Hazards Of Plate Heat Exchangers Fouling

  The plate heat exchanger is a new type of high efficiency heat exchanger which is assembled by a series of metal sheets with a certain corrugated Causes and hazards of plate heat exchangers foulingshape. Plate type heat exchanger is a high-efficiency and energy-saving heat exchange equipment widely used in machinery, electric power, metallurgy, chemical industry, textile, beverage, urban heating and other industries.

  In the field of heat supply, due to improper operation of the water treatment equipment, the softened water that has not reached the softening requirement is directly added to the system, so that the soluble calcium and magnesium salts in the water are thermally decomposed into calcium carbonate and magnesium hydroxide precipitates bonded to the plate heat exchanger. The heated surface of the device forms a hard scale. Due to the poor thermal conductivity of the scale, the heat exchange efficiency of the heat exchanger is reduced and the resistance of the system is increased, thereby affecting the heating effect and causing serious energy waste to the heating unit.

  In industrial systems, fluids with particulate matter and fibers enter the gasket heat exchanger. When the heat exchanger flow rate is not designed properly or the flow path width is less than the allowable width, particles and fibers are slowly deposited at the bottom of the heat exchanger flow path, causing the resistance of the heat exchanger is not smooth, and the heat exchanger is no longer heat exchange, which seriously affects the process operation of the system.
