Due to the long-term use of the heat exchanger equipment, a lot of dirt will be generated such as sediment, microbial adhesion, scale, corrosion products, and slime.These dirt will reduce and damage the heat exchange effect of the heat exchange equipment. The pipeline lines will also be blocked and other series of problems, which will increase the energy loss of the heat exchange equipment load.If the corrosion is serious, the system will be disrupted due to perforation and fracture, etc., and production will be forced to stop.Until now, it has been impossible to completely avoid scaling. Some measures must be taken to prevent or delay the fouling speed, so cleaning the heat exchange equipment is indispensable in the production process.Plate heat exchange can use chemical cleaning, mechanical (physical) cleaning and comprehensive cleaning methods.Equipment cleaning can improve equipment's heat exchange efficiency and save resources. It can also extend the useful life of the device. It can also enhance the production efficiency and quality of equipment and reduce economic losses.
