Plate heat exchanger, the complete set of equipment is composed of plate heat exchanger, balance tank, centrifugal sanitary pump, hot water device (including steam pipeline, hot water injector), bracket and instrument box. It is used for the sterilization and cooling of milk or other hot sensitive liquids. The materials to be processed are advanced into the balance tank, and sent into the heat exchanger by centrifugal sanitary pump. After preheating, sterilization, heat preservation and cooling, all the materials that do not reach the sterilization temperature are changed by the instrument to control the pneumatic return valve, and then go back to the balance tank for reprocessing.
The sterilization temperature of the material is automatically controlled and continuously recorded by the instrument control box, so as to monitor and check the sterilization process. This equipment is suitable for pre sterilization and sterilization of milk. There are two main types of plate heat exchangers: frame type (detachable) and brazing type. The form of plate is mainly composed of three kinds of corrugated plates, horizontal flat corrugated plates and tumor shaped plates.
If the plate heat exchanger is used for a long time, it will cause water leakage. How do I deal with such a problem and appear such a problem? First we need to know the cause of the failure and what causes the leakage so that we can solve it correctly.
Disassemble the reload, if each time is the same two pieces of water leakage between, if the replacement glue pad, still leak here, the plate may be deformed. In this case, we should consider changing a new plate.
The plate heat exchanger is a new type of high efficient plate heat exchanger, which is made up of a series of metal sheets with a certain shape of corrugated metal. Thin rectangular channels are formed between various plates to exchange heat through plates. The plate heat exchanger is an ideal equipment for the heat exchange of liquid - liquid and liquid - vapor. It has the characteristics of high heat transfer efficiency, small heat loss, compact and compact structure, small 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 plate heat exchanger. The area occupied is 1/3 of the tube plate heat exchanger, and the heat recovery rate can reach as high as 90%.
