Heat exchanger unit abj-12512-25Plate heat exchanger is a new type of high-efficiency heat exchanger which is formed by stacking a series of metal sheets with a certain corrugated shape.Thin rectangular channels are formed between various plates to exchange heat through the plates.Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange.It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, easy installation and cleaning, wide application and long service life.Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, it covers an area of one third of the tube heat exchanger, and the heat recovery rate can be as high as 90%.
2. The material of the plate heat exchanger is mainly divided into three materials: stainless steel 304, stainless steel 316L, carbon steel, etc. The performance of the preferred stainless steel material is good.
1.The nominal pressure of the plate heat exchanger is 0.6. 1.0, 1.25, 2.0, 2.5mpa, the test pressure is the working pressure 2.5 times is enough;
Plate type heat exchanger (Plate Type Heat Exchanger) is composed of plate heat exchanger, balance tank, centrifugal sanitary pump, hot water device (including steam pipeline, hot water injector), bracket and instrument box.Used for sterilization and cooling of milk or other heat sensitive liquids.The material to be processed first enters the balance tank, and is sent to the heat exchanger through the centrifugal sanitary pump, after preheating, sterilization, heat preservation, and cooling. Any material that has not reached the sterilization temperature is controlled by the instrument to control the pneumatic return valve and then return.Rebalance the tank.The material sterilization temperature is automatically controlled and continuously recorded by the instrument control box in order to monitor and check the sterilization process.There are two main types of plate heat exchangers: frame type (removable type) and brazing type. The plate types are mainly three types: herringbone corrugated plate, horizontal and straight corrugated plate and knob-shaped plate.
