Description

Technical Field

[0001] This utility model relates to the technical field of carbon dioxide drying equipment, specifically an energy-saving carbon dioxide drying and purification device. Background Technology

[0002] In today's industrial sector, carbon dioxide has extremely wide applications, from carbonation in the food and beverage industry to chemical synthesis, electronics manufacturing, and fire protection. With the expansion of industrial production scale and the increasing demands for product quality, the demand for high-purity carbon dioxide is growing, making carbon dioxide drying and purification technology increasingly crucial.

[0003] Traditional carbon dioxide drying and purification devices have many problems. In the drying stage, many devices use a simple adsorption drying method with a single adsorbent, such as silica gel or activated alumina. These adsorbents have limitations in adsorption capacity and selectivity, making it difficult to meet the requirements for deep drying of carbon dioxide. In order to achieve the required degree of dryness, the adsorbent often needs to be replaced frequently, which not only increases operating costs but also wastes resources. Moreover, in the traditional adsorption drying process, there is a lack of an effective heat recovery mechanism, and a large amount of energy is consumed when regenerating the adsorbent, resulting in high overall energy consumption. Therefore, an energy-saving carbon dioxide drying and purification device is needed to solve the above technical problems. Utility Model Content

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] like Figures 1 to 6As shown, an energy-saving carbon dioxide drying and purification device includes a drying tank 10. Multiple adsorption-drying components 20 are arranged inside the drying tank 10, distributed along the height of the drying tank 10. The adsorption-drying components 20 are used to adsorb moisture from carbon dioxide gas. A support mesh plate 30 is fixedly installed at the top of the drying tank 10. Heating tubes 31 are arranged on the support mesh plate 30. An air inlet pipe 40 with a U-shaped cross-section is connected to the drying tank 10 via a pipe. Two heat exchange tubes 41 are arranged on the outer surface of the air inlet pipe 40, and the two heat exchange tubes 41 are spirally arranged. The gas is spirally wound around the outer surface of the inlet pipe 40 to increase the gas flow time inside the heat exchange tube 41. The heat exchange tube 41 is used to preheat the gas inside the inlet pipe 40. The bottom ends of the two heat exchange tubes 41 are connected by a pipe. The top end of one heat exchange tube 41 is connected to the top of the drying tank 10 by a pipe. The top end of the other heat exchange tube 41 is connected to the exhaust pipe 42 by a pipe. A U-shaped heat insulation sleeve 50 is provided on one side of the drying tank 10. The heat exchange tube 41 is located inside the heat insulation sleeve 50. The heat insulation sleeve 50 is used to reduce the heat loss of the heat exchange tube 41.

[0030] When the heating element 31 is activated, after the carbon dioxide gas enters the drying tank 10 through the inlet pipe 40, it first undergoes adsorption and drying operations through multiple adsorption and drying components 20. The adsorbed and dried carbon dioxide gas then passes through the support mesh plate 30 and enters the top of the drying tank 10. At this point, the heat generated by the heating element 31 further dries the carbon dioxide gas, resulting in a better drying effect. The temperature of the carbon dioxide gas rises, and the heated carbon dioxide gas enters the heat exchange tube 41 through a pipe. The temperature of the heat exchange tube 41 rises, and the spiral heat exchange tube 41 raises the temperature inside the inlet pipe 40, thus preheating the gas inside the inlet pipe 40. This allows for faster drying of the carbon dioxide gas, recovers and utilizes heat, and the insulation sleeve 50 greatly prevents heat loss to the outside, achieving energy-saving effects.

[0031] It should be noted that the heating tube 31 is an electric heating tube, and the shape of the heating tube 31 is serpentine, which is used to increase the heating area inside the drying tank 10, so as to make the heating effect better.

[0032] The adsorption drying assembly 20 includes a support ring 21, a storage mesh cover 22 is attached to the top side of the support ring 21, an adsorbent is disposed inside the storage mesh cover 22, a positioning assembly is disposed between the storage mesh cover 22 and the support ring 21, the positioning assembly is used to position the storage mesh cover 22, and a fixing assembly is disposed between the storage mesh cover 22 and the drying tank 10, the fixing assembly is used to fix the storage mesh cover 22.

[0033] The fixing assembly includes a mounting plate 23 connected to the top side of the storage mesh cover 22 and a fixing hole 101 opened in the inner wall of the drying tank 10. A fixing spring 24 is fixedly connected to one side of the mounting plate 23, and a movable pull head 25 is fixedly connected to the end of the fixing spring 24. A fixing rod 26 is fixedly connected to the side of the movable pull head 25 near the fixing spring 24. The fixing rod 26 passes through the mounting plate 23 and is slidably connected to the mounting plate 23. The diameter of the fixing rod 26 is adapted to the diameter of the fixing hole 101.

[0034] The positioning component includes a positioning hole 211 on the support ring 21 and a positioning rod 27 on the bottom side of the storage net cover 22, with the positioning rod 27 inserted into the interior of the positioning hole 211.

[0035] When fixing the storage mesh cover 22, first pull the movable pull head 25 to move the fixing rod 26 and retract the fixing rod 26 into the mounting plate 23. At this time, the fixing spring 24 is in a stretched state. Then, place the storage mesh cover 22 into the drying tank 10 and insert the positioning rod 27 into the positioning hole 211. At this time, the fixing rod 26 corresponds to the position of the fixing hole 101. Then, slowly release the movable pull head 25. Under the reaction force of the fixing spring 24, the fixing rod 26 is inserted into the fixing hole 101, thus completing the operation of installing the storage mesh cover 22. This makes the operation of installing the storage mesh cover 22 relatively simple. It is also easy to remove the storage mesh cover 22, which makes it easier to replace the absorbent inside the storage mesh cover 22.

[0036] A temperature sensor 11 is installed on the top of the drying tank 10, and a controller 12 is installed on the drying tank 10. The temperature sensor 11 is electrically connected to the controller 12, and the controller 12 is electrically connected to the heating tube 31.

[0037] Temperature sensor 11 is used to detect the temperature inside the drying tank 10 and transmit the temperature signal to controller 12. Controller 12 sets the temperature range inside the drying tank 10 and controls the start and stop of heating tube 31, which can prevent the temperature inside the drying tank 10 from being too high or too low.

[0038] The end of the air inlet pipe 40 away from the drying tank 10 is connected to a fan 43, and the end of the exhaust pipe 42 away from the heat exchange tube 41 is connected to a fan 44. The fans 44 and 43 are used to accelerate the flow of gas.

[0039] The drying tank 10 includes a bottom tank 13, a top tank 14 is provided above the bottom tank 13, and a plurality of middle tanks 15 are installed between the bottom tank 13 and the top tank 14. The plurality of middle tanks 15 are connected together, and an adsorption drying component 20 is installed on the middle tank 15. The adsorption drying component 20 corresponds to the middle tank 15 one by one.
