Abstract

The invention provides a heat exchanger with an anticorrosion and scale-preventing coating and a manufacturing process thereof, and relates to a heat exchanger with a coating in the chemical engineering field. The anticorrosion and scale-preventing coating comprises an inner connection layer and an outer nano-titanium layer. Anionic surfactants and metal elements with high thermal conductivity are added into the connection layer and achieve the effects of transferring heat and preventing the outer layer from being disengaged. The nano-titanium layer is smooth in surface, water scale accumulation is not likely to happen, and the anticorrosion and scale-preventing functions are achieved. The heat transferring portions of various heat exchangers can be coated with the coating, the phenomenon that a heat exchange tube or a heat exchange plate is prone to corrosion and scale formation can be reduced, and the coating on the surface is not liable to being disengaged; meanwhile, heat exchange efficiency can be improved, and the service life of the heat exchanger is prolonged.

Description

technical field [0001] The invention relates to a heat exchanger in the chemical industry, in particular to a coated heat exchanger, in particular to an anti-corrosion and anti-fouling coating heat exchanger and a manufacturing process thereof. Background technique [0002] Heat exchangers are widely used in petrochemical, coal chemical, alumina, power plants, clean energy utilization and other industrial processes. It is composed of heat exchange tubes or heat exchange plates and shells. When used for heat exchange with liquid working fluid, especially if the liquid working fluid contains substances that are easy to corrode and scale, scaling and corrosion will occur during the long-term operation of the heat exchanger, which will bring huge losses to the production of the enterprise. [0003] At present, the liquid heat exchangers used in industry are usually made of stainless steel. Although the material cost and manufacturing cost are greatly increased to reduce corrosio...
