[0040] In this embodiment, the liquid required for the reboiling operation is first introduced from the liquid inlet pipe 202, and passes through the filter sealing box 201 to enter the liquid pipe 2, and flows from the liquid inlet pipe 2 into the interior of the multiple diamond-shaped heat exchange tubes 102, and then steam is introduced through the steam inlet pipe 101, and the multiple diamond-shaped heat exchange tubes 102 are heated by the steam. The geometric structure of the diamond-shaped heat exchange tube can significantly increase the turbulence of the fluid, thereby improving the heat transfer coefficient. Turbulence can more effectively mix the fluid, reduce the thickness of the boundary layer, and make the heat transfer more uniform and efficient. Compared with traditional circular tubes, the outer surface area of ​​the diamond-shaped tube is larger, which helps to increase the total heat exchange area, thereby improving the overall heat transfer efficiency. Moreover, the irregular surface of the diamond-shaped heat exchange tube can generate shear force, which helps to prevent the accumulation of dirt and sediment. The self-cleaning effect can extend the operating cycle of the equipment and reduce the cleaning frequency. The internal corrosion-resistant layer 1 of the diamond-shaped heat exchange tube 102 05 is composed of ceramic powders such as alumina, silica and binders, and has excellent high temperature resistance and corrosion resistance. The heat conductive layer 106 is composed of a composite material of carbon nanotubes and metals such as copper and aluminum. Carbon nanotubes have extremely high thermal conductivity, and the composite material can significantly improve the overall thermal conductivity coefficient. The insulation layer 107 is composed of aerogel, which is a porous solid material mainly composed of silica or other inorganic oxides, and contains a large number of nano-scale pores inside. The strengthening layer 108 is formed by mixing tungsten carbide powder with binders such as cobalt and nickel and then formed by thermal spraying or electroplating process. It has super hardness. The main layer 109 is the main material of the diamond heat exchange tube 102. When the steam enters the steam inlet pipe 101, the anti-collision baffle 104 helps to prevent the steam from suddenly rushing in, thereby increasing the turbulence of the fluid, making the liquid heat transfer more uniform, increasing the total heat exchange area, and improving the overall working efficiency of the reboiler.

[0042] In this embodiment, when the liquid enters the filter sealing box 201, the filter plate 203 located inside the filter sealing box 201 begins to filter the liquid, and the impurities in the liquid are filtered out by the filter plate 203, so that the liquid required for the reboiler operation is purer. When the filter plate 203 needs to be replaced as a whole, the staff unscrews the bolts 205 in turn and manually pulls the handle 206. The handle 206 drives the square plate 204 and the filter plate 203 to be pulled out as a whole, and then replaces them with a new filter plate 203, and re-tightens the bolts 205 to complete the replacement of the filter plate 203 as a whole, so that the liquid can be filtered when entering the reboiler for heating, thereby improving the practicality of the reboiler.

The geometric structure of the diamond-shaped heat exchange tube can significantly increase the turbulence of the fluid, thereby improving the heat transfer coefficient. Turbulence can more effectively mix the fluid, reduce the thickness of the boundary layer, and make the heat transfer more uniform and efficient. Compared with traditional round tubes, the outer surface area of ​​the diamond tube is larger, which helps to increase The total heat exchange area is increased to improve the overall heat transfer efficiency. The irregular surface of the diamond-shaped heat exchange tube can generate shear force, which helps prevent the accumulation of dirt and sediment. The self-cleaning effect can extend the operating cycle of the equipment and reduce the frequency of cleaning. The internal corrosion-resistant layer 105 of the diamond-shaped heat exchange tube 102 is composed of ceramic powder such as alumina, silica and a binder, and has excellent high temperature resistance and corrosion resistance. The heat conductive layer 106 is composed of a composite material of carbon nanotubes and metals such as copper and aluminum. The carbon nanotubes have extremely high thermal conductivity.

The strengthening layer 108 is formed by mixing tungsten carbide powder with a binder such as cobalt and nickel through thermal spraying or electroplating process. It has super hardness. The main layer 109 is the main material of the diamond heat exchange tube 102. When the steam enters the steam inlet pipe 101, the anti-collision baffle 104 helps to prevent the steam from suddenly rushing in, thereby increasing the turbulence of the fluid, making the liquid heat transfer more uniform, increasing the total heat exchange area, and improving the overall working efficiency of the reboiler. When the liquid enters the filter sealing box 201 The filter plate 203 located inside the filter sealing box 201 begins to filter the liquid, and the impurities in the liquid are filtered out by the filter plate 203, so that the liquid required for the reboiler operation is purer.
