1. Drain the liquid in and out of the tube heat exchanger on both sides of the plate heat exchanger. If the liquid cannot be drained, the process liquid can be forced out with water.
2. Rinse both sides of the plate heat exchanger with warm water at about 43 ° C until the water flowing out becomes clear and contains no process fluid.
3. Drain the flushed water and connect it to a local cleaning pump.
4. To clean thoroughly, the in-situ cleaning solution must flow from the bottom to the top of the plate to ensure that the surface of the plate is wet with the cleaning solution. When cleaning the multi-process heat exchanger, the cleaning liquid should be allowed to flow backward for at least 1-2 times to ensure that the surface of the multi-process plate is wet.
5. After cleaning with in-situ cleaning solution, rinse thoroughly with water.
However, the cleaning solution is to use in-situ cleaning solution to flush at the flow rate, or use the in-situ cleaning nozzle diameter to allow flow rate cleaning. If you can perform in-situ cleaning operations according to the established regular cleaning plan before complete contamination, the cleaning effect will be good.
