Plate heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. The marine heat exchanger has been working for a long time. After the process of medium corrosion, erosion, and coking, there will be varying degrees of fouling on the inner and outer surfaces of the pipe, which will be blocked in severe cases. So we should stop work to inspect and clean it completely. Many people may think that there is no harm in the fouling of marine heat exchangers without cleaning. In fact, it is very harmful if the marine heat exchanger is not cleaned.
(1) Fouling caused the heat exchange efficiency of marine heat exchangers to drop significantly, energy consumption increased significantly, and production costs increased
(2) Fouling deteriorates the heat conduction conditions of the marine heat exchanger, and the heat transfer surface is overheated, causing blister, crack, and tube burst safety accidents;
(3) Scaling will cause corrosion damage under the scale, causing leakage of the perforation of the marine heat exchanger, shortening the service life of the equipment and fouling will make the production process unstable. It affects product quality and causes quality accidents. When we use the heat exchanger in the future, we can develop a good habit of regular cleaning and maintenance, so as to extend the service life of the marine heat exchanger.
