The heat exchanger is a universal equipment widely used in petroleum, chemical, power, metallurgy, food, light industry, refrigeration, pharmacy and machinery industries. Because of the importance of the heat exchanger in the chemical industry, the research on heat exchange equipment is highly valued by governments and research institutions of various countries in the world. The performance of the system not only directly affects the smooth progress of each department and the control of product quality, but also may cause various problems of high energy consumption, low efficiency, poor reliability and the like. In a general chemical plant, the investment of heat exchange equipment accounts for about 10-20% of the total investment; in refineries, it is about 35% to 40%. In industrial production, heat exchange equipment mainly functions to transfer heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the temperature of the fluid reaches the index specified by the process, and the requirement on the process flow is met. In addition, the heat exchange equipment is also an effective device for recovering waste heat, waste heat and particularly low-level heat energy. In an acid making system, a heat exchanger is important equipment for fully utilizing heat energy. In industrial production, heat exchange equipment of different forms and structures appears due to different purposes, working conditions and material characteristics. According to the action principle or heat transfer mode, the method can be divided into: direct contact type, heat accumulation type, dividing wall type, intermediate heat carrier type heat exchangers and the like. Dividing wall type heat exchangers can be classified into tubular type, plate type and the like. The tube heat exchanger is a heat exchanger that transfers heat through the wall surface of a tube, and can be roughly classified into a coil heat exchanger, a double-tube heat exchanger, a wound heat exchanger, and a shell-and-tube heat exchanger according to the structural form of a heat transfer tube.
