Plate heat exchangers are ideal for heat exchange between liquid-liquid and liquid-vapor. The utility model has the advantages of high thermal efficiency, small heat loss, compact and light structure, small occupied area, Cleaning and convenient installation, wide application and long service life. In the case of the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more. Plate heat exchangers are widely used in metallurgy, petroleum, chemical, food, pharmaceutical, shipbuilding, textile, paper and other industries. They are excellent equipment for heating, cooling, heat recovery and rapid sterilization.

The whole machine is equipped with two types: ordinary structure (not often used for washing and unloading) and hanging structure (for frequent use of washing and unloading). The common structure consists of main parts such as herringbone corrugated sheets, gaskets, compression plates, upper and lower positioning bolts, and compression bolts. The hanging structure is composed of herringbone corrugated sheets, gaskets, fixed pressing plates, intermediate plates, movable pressing plates, brackets, upper and lower positioning beams, and compression bolts.

Due to the special action of the corrugated surface of the plate, the plate heat exchanger changes the direction of the velocity of the fluid along the narrow curved channel, causing the fluid to stir strongly at a small flow rate (Rc=200). The end movement accelerates the destruction of the fluid boundary layer, strengthens the heat transfer process, effectively improves the heat transfer capacity, and has a compact structure, low metal consumption, large operational flexibility, low heat loss, installation, inspection It has the advantages of convenient washing and dismounting, strong corrosion resistance and long service life. The flow of the heat exchanger is composed of a plurality of plates assembled according to a certain process and the technical requirements of the demanding side. When assembled, the A plate and the B plate are alternately arranged, and the mesh channels are formed between the plates, and the four corner hole distribution pipes and the converging pipes are formed. The gasket seals the cold and heat medium in the heat exchanger, and at the same time separates the cold and heat medium reasonably without mixing. The cold and hot fluids flow in the channel, and the countercurrent can flow downstream. During the flow, the hot and cold fluid exchanges heat through the wall. The combination of the flow of the plate heat exchanger is formed by different reversing plates and different assemblies. The process combination can be divided into single flow, multi-process and vapor-liquid exchange process, and mixed flow form. The process combination of the heat exchanger is selected according to the process conditions.
