Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high thermal efficiency, small heat loss, compact and light structure, small floor area, convenient installation and cleaning, wide application and long service life. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, the floor area is one third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90%. Plate heat exchanger is widely used in metallurgy, petroleum, chemical industry, food, pharmaceutical, shipping, textile, papermaking and other industries. It is an excellent equipment for heating, cooling, heat recovery and rapid sterilization.
The whole machine is equipped with two kinds of common structure (not often used for dismantling and washing conditions) and suspension structure (used for working conditions with frequent dismantling and washing). The common structure is composed of herringbone corrugated plate, sealing gasket, pressing plate, upper and lower positioning bolts, compression bolts and other main parts. The suspension structure is composed of herringbone corrugated plate, sealing gasket, fixed pressing plate, intermediate plate, movable pressing plate, bracket, upper and lower positioning beam, compression bolt and other main parts.
