How to deal with the import plate for dirt
Imported plate heat exchanger for welding type, can not be disassembled, can only be cleaned, the specific steps are as follows:
1, water backwash:
Along the direction of the opposite direction of the pump, pipe, heat exchanger, the use of water with a certain pressure for continuous open washing, as far as possible to plug the heat exchanger debris clean.
2, pickling:
The acid, corrosion inhibitor, surfactant and water according to a certain proportion of preparation, and then from the bottom up into the heat exchanger, the soaking time, and the full scale after the reaction, then cycle pickling, final dilution. The main purpose is to remove the heat exchanger inside the scale.
3, passivation treatment:
The NaOH, Na 3P04, softened water, according to a certain proportion of the use of dynamic circulation of the heat exchanger for alkali washing, so that after pH >7 rinse with water can be. The purpose is to neutralize the residual acid, so that the heat exchanger is not corroded. The imported heat exchanger cleaning procedure is complex, the cost is high, the result is not easy to observe, especially in the operation period is not easy to operate.
In order to make the plate heat exchanger customers maintained in good condition, ARD AI Reed with years of technical experience accumulated over the years, with "dismantling, cleaning" and "improve the operation" and "local service" rich customers in order to make the plate heat exchanger is maintained in good condition, ARD Ai Rui with years of technical experience accumulated over the years. "Dismantling, cleaning" and "improve the operation" and "local service" and other rich service menu, carry out maintenance services.
