⑴ the heat exchanger on both sides of the liquid out of the mouth of the discharge. If the row can not do, can be used to force the liquid out of water.

⑵ rinse with water at about 43 ° C from both sides of the heat exchanger until the effluent water becomes clear and free of process fluid.

⑶ rinse the water out of the heat exchanger, connect the local cleaning pump. (See above for "board cleaning precautions" for cleaning agents)

⑷ To clean thoroughly, it is necessary to make the bottom of the in situ cleaning solution to the top of the flow to ensure that all the surface of the plate with a cleaning solution wet. When cleaning the multi-process heat exchanger, it is necessary to reverse the flow of cleaning fluid at least 1 2 of the cleaning time to ensure that all the processes of the plate surface wet.

⑸ with in situ cleaning solution after cleaning, and then rinse thoroughly with water.

If the heat exchanger is used as a cooling medium for brine, before the cleaning operation, should first try to row of brine, and then rinse the heat exchanger with cold water again. If all the brine side ends are rinsed before cleaning the solution on both sides of the heat exchanger with heat, the corrosion of the equipment will be minimal.

(6) The best cleaning solution is to use the in situ cleaning solution to rinse at the maximum flow rate or to allow the maximum flow rate to be allowed at the maximum allowable flow rate of the nozzle diameter of the nozzle. The maximum permissible flow rate is 260GPM, the nozzle diameter is 1 inch. ). If the cleaning can be done in accordance with the regular cleaning plan before thorough contamination, the cleaning effect will be better.
