Plate Heat Exchanger Plate Cleaning Services

  Plate heat exchanger is an efficient heat exchange equipment. Due to its high heat transfer efficiency, compact structure and convenient assembly and disassembly, it has been widely used in many fields in the 1980s. At the same time, the centralized heating system was also cited, and it was quicklyPlate Heat Exchanger  Cleaning Services promoted. However, due to the small flow cross section of the plate heat exchanger, the efficiency of the heat exchanger is reduced due to fouling and clogging, which affects the heating effect. Therefore, the selection of a reasonable cleaning method has become a necessary means to improve the heat exchange efficiency and extend the service life of the equipment. Cleaning the plate heat exchanger plates is a very important task, so what should you pay attention to when cleaning the plates?

(1) The solution should maintain a certain flow rate during chemical cleaning, generally 0.8-1.2 m/s. The purpose is to increase the turbulence of the solution.

(2) Chemical cleaning solution should be used for different scaring. In addition to the often used diluted soda ash solution, a 5% nitric acid solution can be used for scale. For the scale generated in the production of soda ash, a 5% hydrochloric acid solution can be used. However, chemical cleaners that corrode the plates should not be used.

(3) It is not allowed to brush stainless steel plates with carbon steel brushes during mechanical (logistics) cleaning to avoid corrosion of the plates. At the same time, the surface of the plate cannot be scratched or deformed.

(4) The cleaned plate should be rinsed with water and dried, and the plate should be prevented from being deformed.
