Information

Specific steps for cleaning scale of tranter gasketed plate heat exchanger:

tranter gasketed plate heat exchanger

1) Washing: Before pickling the tranter gasketed plate heat exchanger, first open the heat exchanger to make the heat exchanger free of impurities such as mud and scale, which can improve the effect of pickling and reduce Acid consumption for pickling.
2) Pour the cleaning liquid into the cleaning equipment, and then into the tranter gasketed plate heat exchanger.
3) Pickling: Statically soak the tranter gasketed plate heat exchanger filled with acid solution for 2 hours, and then continuously and dynamically circulate it for 3-4 hours, during which the positive and negative cleaning is performed alternately every half an hour. After the pickling is finished, if the pH of the acid is greater than 2, the acid can be reused, otherwise, the acid should be diluted, neutralized and drained.
4) Alkaline washing: After pickling, use NaOH, Na3P04 and demineralized water to prepare a certain proportion. Use dynamic circulation to prepare demineralized water in a certain proportion. Use dynamic circulation to tranter gasketed plate heat exchangers. Carry out alkaline washing to achieve acid-base neutralization, so that the tranter gasketed plate heat exchanger no longer corrodes.
5) Washing with water: After the alkaline washing, use clean, softened water to repeatedly rinse the tranter gasketed plate heat exchanger for half an hour to thoroughly rinse the residue in the plate heat exchanger.
6) Record: During the cleaning process, the time of each step should be strictly recorded to check the cleaning effect.

After cleaning the tranter gasketed plate heat exchanger, the heat exchanger must be subjected to a pressure test, and it can be used only after it is qualified.
