Cleaning steps of plate heat exchanger

2018-11-10 Source: Author: Anonymous read: 【Print this page】

No matter what kind of mechanical equipment, scaling will inevitably occur after a period of use, which requires us to clean it, and plate heat exchangers are no exception. So do you know what are the cleaning steps for plate heat exchangers? It doesn't matter if you don't know, today I will introduce it to you, and take a look at the following article.
(1) Drain the liquid in and out of the tube heat exchanger on both sides of the plate heat exchanger. If it cannot be drained, the process liquid can be forced out with water.
(2) Rinse with warm water at about 43 C from both sides of the heat exchanger until the flowing water becomes clear and contains no process fluid.
(3) Drain the flushed water out of the plate heat exchanger and connect it to the local cleaning pump.
(4) For thorough cleaning, the in-situ cleaning solution must flow from the bottom to the top of the plate to ensure that all the surface of the plate is wet with the cleaning solution. When cleaning the multi-process heat exchanger, the cleaning liquid must be allowed to flow backward for at least 12 cleaning times to ensure that the surface of all plates in the multi-process is wet.
(5) The best cleaning solution is: use the in-situ cleaning solution to flush at the maximum flow rate, or use the in-situ cleaning nozzle diameter to allow the maximum flow rate cleaning (the maximum flow rate allowed for a nozzle diameter of 2 inches is 260 GPM, and the maximum allowed for a nozzle diameter of 1 inch Flow rate 67GPM). If you can perform in-situ cleaning operations according to the established regular cleaning plan before complete contamination, the cleaning effect will be better.
(6) After cleaning with in-situ cleaning solution, rinse thoroughly with water. If the heat exchanger uses brine as a cooling medium, before the cleaning operation is started, the brine should be drained as much as possible, and then the heat exchanger should be flushed with cold water. If all sides of the brine heat exchanger are cleaned before using a hot-in-place cleaning solution to clean both sides of the plate heat exchanger, the corrosion of the equipment will be minimal.
The above is all the content about the plate heat exchanger introduced to you today, I hope to bring you some help.
