[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 As shown, this embodiment of the present invention provides an energy-saving and consumption-reducing carbon dioxide distillation column structure, specifically including a heating tank body 1, a distillation column body 2 disposed on the front side of the heating tank body 1, and the distillation column body 2 being connected to the heating tank body 1. A top cover 3 is placed on the top of the heating tank body 1, a heat recovery pipe 4 is disposed on the outer side of the heating tank body 1, and a heat insulation shell 5 is fitted on the surface of the heating tank body 1. A water tank 6 is placed on the right side of the heating tank body 1, a partition plate 7 is fixed in the middle of the interior of the water tank 6, a water inlet pipe 8 is connected to the lower left side of the water tank 6, a water pump 9 is fixed to the lower front side of the water tank 6, the water pump 9 is connected to the water tank 6, a water inlet pipe 10 is connected to the front side of the water pump 9, a drain pipe 11 is connected to the upper front side of the water tank 6, and a water intake valve 12 is connected to the upper right side of the water tank 6.

[0025] Specifically, in this embodiment, when the operator needs to distill carbon dioxide, the operator injects carbon dioxide into the interior of the heating tank body 1 through the inlet pipe 20. The heating tank body 1 heats the carbon dioxide, and under certain temperature and pressure, the carbon dioxide is heated into a liquid. At this time, the operator injects the liquid carbon dioxide into the interior of the distillation column body 2 to cool the liquid carbon dioxide, thereby completing the distillation process of carbon dioxide. At this time, the operator turns on the water pump 9, which then injects the cold water below the water tank 6 into the interior of the heat recovery pipe 4 through the water inlet pipe 10. The cold water inside the heat recovery pipe 4 recovers the heat inside the heating tank body 1, and the temperature of the cold water inside the heat recovery pipe 4 rises. After the heat inside the heating tank body 1 has been recovered, the water pump 9 turns on again, and the water pump 9 injects the cold water below the water tank 6 back into the heat recovery pipe 4, thereby pushing the hot water inside the heat recovery pipe 4 into the upper drain pipe 11 and into the upper part of the water tank 6 for storage, so that the operator can use it later.

[0026] Please see Figures 1 to 5As shown, a groove 13 is provided on the outer surface of the heating tank body 1. The groove 13 is spiral-shaped. The heat recovery pipe 4 is fixedly connected to the inner wall of the groove 13. The top of the water tank 6 is fitted with a heat insulation sleeve 15. Both the heat insulation sleeve 15 and the heat insulation shell 5 are vacuum heat insulation plates. The heat recovery pipe 4 is made of copper-aluminum alloy. The groove 13 allows the heat recovery pipe 4 to be wound around the surface of the heating tank body 1. The heat recovery pipe 4 is made of copper-aluminum alloy with good thermal conductivity, which can quickly recover the heat inside the heating tank body 1 and improve the heat recovery efficiency. The heat insulation shell 5 and the heat insulation sleeve 15 can prevent heat from being lost to the outside and prevent resource waste.

[0027] Please see Figures 1 to 5 As shown, one end of the water inlet pipe 10 passes through the heat insulation shell 5 and is connected to the bottom end of the heat recovery pipe 4. One end of the drain pipe 11 passes through the heat insulation shell 5 and is connected to the top end of the heat recovery pipe 4. Check valves 14 are installed on one side of the surface of both the water inlet pipe 10 and the drain pipe 11. The water flows into the heating tank body 1 through the check valve 14 on the surface of the water inlet pipe 10, and the water flows into the water tank 6 through the check valve 14 on the surface of the drain pipe 11. The flow direction of the water can be controlled by the check valve 14 to prevent backflow.

[0028] Please see Figures 1 to 5 As shown, a water level sensor 16 is fixed on the lower left side of the front of the water tank 6. The sensor head of the water level sensor 16 extends into the interior of the water tank 6. A buzzer 17 is fixed on the right side of the front of the water tank 6. The water level sensor 16 and the buzzer 17 work together. When a certain amount of cold water awaiting heat recovery is used at the bottom of the water tank 6, the water level sensor 16 will be triggered, and the buzzer 17 on one side will be turned on so that the staff can add cold water to the bottom of the water tank 6 through the water inlet pipe 8.

[0029] Please see Figures 1 to 5 As shown, the top of the top cover 3 is connected to an electrically controlled gas valve 18, the top of the electrically controlled gas valve 18 is connected to a buffer tank 19, and the top of the buffer tank 19 is connected to an air inlet pipe 20. When carbon dioxide is injected into the heating tank body 1, the electrically controlled gas valve 18 can buffer a large amount of gas.
