Shandong plate heat exchanger plate heat exchanger manufacturer specializing in the supply of high-quality sales, good quality and low price - Shandong Jintai heat Technology Co., Ltd., specializing in plate heat exchanger production, sales, quality and competitive prices whispered, the industry leader in plate heat exchangers is a new and efficient heat exchanger consists of a series of corrugated metal sheets with a certain shape made of stacked. Formed between the various plates of thin rectangular channel, through heat exchange plates. Plate heat exchanger is liquid - liquid, liquid - ideal for steam heat exchange equipment. It has a high heat transfer efficiency, heat loss, compact and lightweight, small footprint, easy installation and cleaning, widely used, and long service life. Under the same pressure loss, the heat transfer coefficient than the column tube heat exchanger 3-5 times higher, covers an area one-third tubular heat exchanger, heat recovery can be as high as 90%. Plate heat exchanger, this equipment by the plate heat exchanger, balance tank, centrifugal sanitary pumps, hot water installations (including steam piping, hot water is injected into the device), the bracket and meter boxes and other components. Sterilization of milk or other heat-sensitive liquids used for cooling. To deal with the material before entering the balance tank, the centrifugal pump into the heat exchanger of Health, after preheating, sterilization, heat, cooling the segments, who have not reached the sterilization temperature materials, instrumentation control commutation by pneumatic return valve, then Back to the balance tank reprocessed. Material from the instrument sterilization temperature control box for automatic control and continuous recording, in order to monitor and check the sterilization process. This device is suitable for pre-sterilized milk, pasteurization. Plate heat exchanger type main (removable) and brazed frame into two categories, mainly in the form chevron plate corrugated board, corrugated board and horizontal flat plate-shaped tumor three. Features (plate heat exchangers and shell-and-tube heat exchanger relatively) a. Heat transfer coefficient due to different corrugated plates are inverted, a complex flow channel, the fluid flow path between the corrugated board was rotated within a three-dimensional flow, energy turbulence at low Reynolds number (typically Re = 50 ~ 200), the heat transfer coefficient is so high, generally considered to be a shell and tube 3 to 5 times. b. logarithmic mean temperature difference, small temperature difference at the end of the shell and tube heat exchangers, the two fluids in the flow tube and shell, respectively, on the whole cross-flow flow, logarithmic mean temperature difference correction factor is small, and the plate heat exchangers are mostly current or countercurrent flow pattern, the correction coefficient is usually around 0.95, In addition, cold and hot fluid flow in the plate heat exchanger are parallel to the heat transfer surface, without bypass, thus making the plate heat exchanger the end of the temperature difference is small, water heat exchanger can be less than 1 ℃, and shell and tube heat exchanger is generally 5 ℃ fff. Plate heat exchanger c. compact plate heat exchanger structure, small footprint, the unit volume heat transfer area is 2 to 5 times the shell and tube, and also did not want to shell and tube bundle maintenance reserve out of place, thus achieving the same heat transfer, plate heat exchanger shell and tube area is about to change heat 1/5 ~ 1/8. . c easy to change heat transfer area or the process, as long as the increase or decrease a few plates, can be achieved by increasing or decreasing the heat transfer area of ??the object; sheet arranged alter or replace a few plates, can achieve the desired combination of flow adapt to new conditions exchanger, shell and tube heat exchangers and heat transfer area is almost impossible to increase. d. light weight plate heat exchanger plate thickness of only 0.4 ~ 0.8mm, while the thickness of the shell and tube heat exchanger tubes of 2.0 ~ 2.5mm, than the plate heat exchanger shell and tube housing much heavier frame, plate heat exchanger tube is generally only about 1/5 of the weight of shell. e. low prices the same material, in the same heat transfer area, plate heat exchangers prices 40% to 60% lower than the shell and tube about. f. make convenient plate heat exchanger heat transfer plate is the use of punching, high degree of standardization and mass production, shell and tube heat exchangers are generally handmade. g. Easy to clean frame plate heat exchanger as long as loose bolts can loosen the plate beam, remove the plate for mechanical cleaning, which requires frequent cleaning equipment heat transfer process is very convenient. Plate heat exchanger i. Heat loss is small plate heat exchanger heat transfer plate only wrapper plate exposed to the atmosphere, and therefore heat loss is negligible and does not require insulation measures. The shell and tube heat exchanger heat loss, need insulation. h. the capacity of the smaller shell and tube heat exchanger is 10% to 20%. i. pressure loss per unit length of the large heat transfer surface due to the small gap between the heat transfer surface irregularity, and therefore greater than the pressure loss of the conventional smooth tube. j. difficult to scale because of the internal fully turbulent, so easy to scale, and its scaling factor is only a shell and tube heat exchanger 1/3 ~ 1/10. k. working pressure should not be too large, medium temperature is not too high There may leak using plate heat exchanger gasket seal, working pressure is generally not more than 2.5MPa, medium temperature should be lower than below 250 ℃, otherwise it may leak. l. easily blocked because of a very narrow passage between the plates, generally only 2 ~ 5mm, when the heat transfer medium contains large particles or fibrous material, easy to plug the passage between the plates.
