Background
The main material of the heat exchange heat backup is metal material, based on sensible heat exchange, when two fluids with different temperatures pass through the metal surface, heat exchange is carried out, so that the hotter fluid is cooled, and the sensible heat released by the cooling is realized by the heat exchange on the metal surface. At present, heat exchange tubes of heat exchange equipment are made of various materials, and the main materials of the heat exchange equipment with low cost are carbon steel and hot-dip galvanized steel tubes, so most users select the heat exchange equipment made of the two materials, however, the corrosion and scaling prevention performance of the heat exchange equipment is serious, and the corrosion and scaling problems are difficult to solve in most environments. The heat exchange equipment is contacted with heat exchange fluid, so that the metal surface of the heat exchange equipment is very easy to generate serious scaling phenomenon, scaling not only can greatly reduce the heat exchange efficiency of the heat exchange equipment, but also the service life of the heat exchange equipment is seriously influenced by under-scale corrosion caused by inorganic salt and scale covering, and serious potential safety hazard is brought to production. The technical problem to be solved by the invention is how to design a scheme for improving the anti-scaling performance of the heat exchange equipment so as to prolong the service life of the equipment.
