How it works?
The plate heat exchanger can be especially used for thermal treatment such as heat-up and cool-down of viscous medium or medium contains coarse particles and fiber suspensions in sugar, papermaking, metallurgy, ethanol and chemical industries.
Special design of the heat exchange plate ensures better heat transfer efficiency and pressure loss than other kinds of heat exchange equipment in the same condition. Smooth flow of the fluid in the wide gap channel is also ensured. It realizes the aim of no“ dead area” and no deposition or blockage of the coarse particles or suspensions.
Alumina, mainly sand alumina, is raw material for alumina electrolysis. The production process of alumina can be classified as Bayer-sintering combination. The application of plate heat exchanger in alumina industry successfully reduces erosion and blockage, which in turn increased heat exchanger efficiency as well as production efficiency.
The heat exchanger is applied in the middle temperature drop workshop section in the decomposition and grading work order in the production process of alumina, which is installed on the top or bottom of decomposition tank and used for reducing the temperature of aluminum hydroxide slurry in the decomposition process.
