Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and in particular relates to a high-temperature tube heat exchanger. Background Art

[0002] Shell and tube heat exchanger is also called shell and tube heat exchanger. It is a wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale; but the heat transfer coefficient is low and the floor space is large. It can be made of various structural materials (mainly metal materials) and can be used under high temperature and high pressure. It is the most widely used type. Shell and tube heat exchangers include fixed tube plate steam-water heat exchanger, shell and tube steam-water heat exchanger with expansion joint, floating head steam-water heat exchanger, U-shaped shell and tube steam-water heat exchanger, corrugated shell and tube steam-water heat exchanger, segmented water-water heat exchanger and other types. The main control parameters of shell and tube heat exchanger are heating area, hot water flow, heat exchange capacity, heat medium parameters, etc.

[0003] During the long-term use of commonly used high-temperature tubular heat exchangers, water flows continuously through the inside of the device, which will form scale residues. The scale residues will gradually accumulate after repeated use. The accumulated scale will begin to slow down the overall flow rate of the device and affect the overall heat exchange effect of the device. For this reason, we propose a high-temperature tubular heat exchanger. Utility Model Content

[0028] In a specific embodiment of the present utility model, the water pipe 1103 will guide the water flow into the heat exchange component 11 for heat exchange. At the same time, the heat conduction plate 1104 and the heat pipe 1105 are linked to each other. The heat conduction plate 1104 plays a role of absolute separation between the cold and hot fluid channels, ensuring that the two fluids will not mix, thereby maintaining their respective temperature characteristics, thereby achieving the effect of heat exchange.

[0037] Working principle: This high-temperature tubular heat exchanger guides water into the water pipe 2 through the water inlet 1, and uses the pressure block 3 and the pressure pump 4 to help the water flow to exchange heat inside the shell 6. At the same time, the heat exchange component 11 will start, and use its own structure and water flow to achieve the required heat exchange effect. While exchanging heat, it will also process scale at any time according to its own structure to prevent scale accumulation from affecting the water flow, thereby affecting the overall heat exchange efficiency of the device, and further improving the overall heat exchange effect and service life of the device. The heat exchange component 11 fixes the connecting platform 1102 inside the shell 6 through the fixed base 1101 to ensure the overall stability of the heat exchange component 11, and further improve the stability of the heat exchange component 11. The water pipe 1103 will guide the water flow to the inside of the heat exchange component 11 for heat exchange. At the same time, the heat conduction plate 1104 and the heat pipe 1105 are linked to each other, and the heat conduction plate 1104 plays a role between the cold and hot fluid channels. The effect of absolute separation ensures that the two fluids will not mix, thereby maintaining their respective temperature characteristics, thereby achieving the effect of heat exchange. The rotating base 1106 will drive the central shaft 1107 to rotate under the drive of the flushing water pressure, thereby driving the rotation of the rotating block 1108, and at the same time, the descaling plate 1109 fixed on the surface of the rotating block 1108 will also rotate to continuously rotate the inside of the water pipe 1103, thereby preventing scale accumulation from affecting the water flow rate, further improving the heat exchange effect and service life of the device, the limit block 1110 can help prevent the descaling plate 1109 from being displaced and falling during rotation, thereby further improving the overall safety of the device, the fixed frame 8 can help provide a force point when the surface of the shell 6 is displaced, further improving the overall functionality of the device, the water tank 12 can store water that needs to be reserved, prevent insufficient water flow in emergencies, and further improve the overall functionality and safety of the device.
