Plate heat exchanger optimization design direction
In recent years, plate heat exchanger technology has become more and more mature, with high heat transfer efficiency, small volume, light weight, low fouling coefficient, convenient disassembly, many kinds of plates and wide application range, which has been widely used in the heating industry. Plate heat exchangers are classified into detachable, welded, brazed and shell-and-shell types according to different assembly methods. Since the detachable plate heat exchanger is easy to disassemble and clean, the area of the heat exchanger is increased and decreased easily.And it is used more in the heating project. The detachable plate heat exchanger is limited by the heat resistance temperature of the rubber gasket and is suitable for water-water heat transfer.
Improving the efficiency of plate heat exchangers is a comprehensive economic benefit problem and should be determined through technical and economic comparisons. Improve the heat transfer efficiency of the heat exchanger and reduce the resistance of the heat exchanger should be considered at the same time, and the material of the PHE plate and the rubber gasket and the installation method should be reasonably selected to ensure the safe operation of the equipment and prolong the service life of the equipment.
