Working principle of detachable plate heat exchanger
Removable plate heat exchanger, also known as detachable plate heat exchanger, is a compact, heat-exchange heat exchanger, which has been used for decades. The detachable plate heat exchanger is mainly used in the processing and processing of milk. Due to its small size, easy disassembly and cleaning, and the like, it is widely used in food processing, beverage, beer processing and pharmaceutical processing. Up to now, detachable plate heat exchangers have been widely used in various industries such as petrochemical, electric power, papermaking, metallurgy, fuel ethanol, waste heat recovery, and district heating. They act as heaters, coolers, and even as a process in these processes. Evaporator and condenser in the refrigeration system.
Heat exchanger should be hydraulic pressure test 1.5 times the working pressure, the hot water part should not be less than 0.4MPa, the steam part should not be lower than the steam supply pressure plus 0.3MPa. The pipes connected to the heat exchanger should be cleaned to prevent debris such as welding slag and sand from entering the heat exchanger and causing blockage. The inlet and outlet of the hot and cold medium shall be connected and installed in the direction specified by the factory nameplate. In order to facilitate maintenance, sufficient space should be reserved around the heat exchanger.
Removable spiral plate heat exchanger. Except for the sealing structure at both ends of the spiral plate heat exchanger spiral-plate heat exchanger, the other is completely the same as the non-removable type. For mechanical cleaning purposes, the detachable spiral channel, open at one end, is sealed with a flat cover and gasket to prevent fluid from leaking into the atmosphere or shorting fluid in the same channel.
