Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide recovery technology, and in particular to a device for recovering residual gas from a carbon dioxide storage tank. Background Technology

[0002] Carbon dioxide, a carbon oxide compound with the chemical formula CO2 and a molecular weight of 44.0095, is a colorless and odorless gas at room temperature and pressure, although its aqueous solution has a slightly acidic taste. It is a common greenhouse gas and a component of air. Carbon dioxide is generally produced by calcining limestone at high temperatures or by reacting limestone with dilute hydrochloric acid. Its main applications include refrigerating perishable foods (solid), acting as a refrigerant (liquid), manufacturing carbonated soft drinks (gaseous), and serving as a solvent for homogeneous reactions (supercritical state). Carbon dioxide is typically stored in gas tanks. After the gas in the tank is used up, residual gas usually remains. Directly releasing this residual gas not only increases greenhouse gas emissions but also wastes a significant amount of carbon dioxide resources.

[0003] However, when recovering residual gas from carbon dioxide storage tanks, it is necessary to connect and fix them to the recovery device for convenient recovery. However, the storage tanks for residual gas recovery are of different sizes, so a structure that can be used to fix storage tanks of different sizes is needed to improve the applicability of the device. Therefore, it is necessary to design a carbon dioxide storage tank residual gas recovery device. Utility Model Content

[0025] In this embodiment, a support plate 8 is fixedly connected to the upper surface of the placement platform 3 at the rear. A first motor 9 is installed on the upper surface of the support plate 8. A screw 10 is fixedly connected to the output end of the first motor 9.

A clamping block 13 is fixedly connected to one end of the electric telescopic rod 12.

[0026] In practical use, depending on the height of the gas tank, the first motor 9 on the support plate 8 is started to drive the screw 10 to rotate, so that the sliding frame 11 moves to a suitable position in the middle of the gas tank. Then, the gas tank is placed in the placement slot 4 of the placement platform 3. Under the action of the first air pump 7, the residual gas inside the gas tank is transported and recovered through the collection pipe 6 connected to the collection bag 5. The support leg 2 on the base plate 1 can increase the height of the placement platform 3, making it easier to install the collection bag 5 for better collection of carbon dioxide. The electric telescopic rod 12 on the sliding frame is started to drive the clamp 13 to fix and hold the gas tank. It is suitable for gas tanks of different sizes, improving applicability.

[0027] In this embodiment, a filter box 14 is fixedly connected to one end of the collection pipe 6. A primary filter plate 15 is attached to the lower inner wall of the filter box 14, and a secondary filter plate 16 is attached to the upper inner wall of the filter box 14. A first air pipe 17 is fixedly connected to the outer surface of the filter box 14, and a second air pump 18 is installed on the outer surface of the first air pipe 17.

[0028] In practical use, the carbon dioxide extracted from the storage tank is pumped into the filter box 14 by the first air pump 7. After passing through the first-stage filter plate 15 and the second-stage filter plate 16, impurities and dust are filtered.

[0029] In this embodiment, a water removal tank 19 is fixedly connected to one end of the first air pipe 17. A sulfuric acid tank 20 is fixedly connected to the lower surface of the water removal tank 19. An installation plate 21 is fixedly connected to the upper inner top wall of the water removal tank 19. A second motor 22 is installed on the upper surface of the water removal tank 19. A drive gear 23 is fixedly connected to the output end of the second motor 22.

The guide pipe 26 passes through the sulfuric acid tank 20. A drive pump 27 is installed on the inner bottom wall of the sulfuric acid tank 20. A spraying rod 28 is fixedly connected to the outer surface of the guide pipe 26.

[0030] In practical use, the filtered carbon dioxide enters the dewatering tank 19 through the second air pump 18. Then, the second motor 22 on the mounting plate 21 is started to drive the drive gear 23 to rotate, which in turn drives the rotating rod 25 on the driven gear 24 to rotate. This causes the guide pipe 26 on the rotating rod 25 to rotate, and the driving pump 27 can pump the concentrated sulfuric acid in the sulfuric acid tank 20 into the guide pipe 26. The concentrated sulfuric acid is then sprayed through the spray rod 28, which facilitates better fusion and dehydration of carbon dioxide and concentrated sulfuric acid, resulting in uniform fusion and improved dehydration efficiency.

[0032] In practical use, driven by the third air pump 30, carbon dioxide is easily drawn into the dehydration tank 19 for dehydration and then enters the collection tank 31 through the second air pipe 29 for collection. After liquefaction, the carbon dioxide is discharged through the drain pipe 32.

[0033] In this embodiment, a compressor cooler 33 is installed on the inner top wall of the collection tank 31.

[0034] In practical use, the compressor refrigeration unit 33 can liquefy the carbon dioxide inside the collection tank 31 for easy storage and recycling.

[0036] In actual use, the operating door 34 allows for easy opening of the filter box 14 to clean and replace the internal primary filter plate 15 and secondary filter plate 16, facilitating better filtration.

[0037] In this embodiment, a sealing airbag 35 is placed on the inner sidewall of the placement groove 4.

[0038] In practical use, the sealing airbag 35 can deform and fit the size of the gas tank to ensure that the placement slot 4 fits and seals better with the gas tank, thus ensuring the recovery rate of residual gas.

[0039] Working Principle: During use, based on the height of the gas storage tank, the first motor 9 on the support plate 8 is activated to drive the screw 10 to rotate, causing the sliding frame 11 to move to a suitable position in the middle of the gas storage tank. Then, the gas storage tank is placed in the placement slot 4 of the placement platform 3. Under the action of the first air pump 7, the residual gas inside the gas storage tank is transported and recovered through the collection pipe 6 connected to the collection bag 5. The support legs 2 on the base plate 1 can increase the height of the placement platform 3, making it easier to install the collection bag 5 for better carbon dioxide collection. The electric telescopic rod 12 on the sliding frame is activated to drive the clamping block 13 to fix and hold the gas storage tank, which is suitable for gas storage tanks of different sizes, improving applicability. Driven by the extraction of the first air pump 7, the carbon dioxide extracted from the storage tank is pumped into the filter box 14. After passing through the first-stage filter plate 15 and the second-stage filter plate 16, impurities and dust are filtered. The filtered carbon dioxide enters the dewatering tank 19 through the second air pump 18. Then, the second motor 22 on the mounting plate 21 is activated to drive the drive gear 23 to rotate. Then, the driven gear 24 drives the rotating rod 25 to rotate, causing the guide pipe 26 on the rotating rod 25 to rotate. The driving pump 27 can pump the concentrated sulfuric acid inside the sulfuric acid tank 20 into the guide pipe 26 and spray the concentrated sulfuric acid through the spray rod 28, which facilitates better fusion and dehydration of carbon dioxide and concentrated sulfuric acid, resulting in uniform fusion and improved dehydration efficiency. Driven by the third air pump 30, carbon dioxide is easily drawn into the dehydration tank 19 for dehydration and then enters the collection tank 31 through the second air pipe 29 for collection. After liquefaction, the carbon dioxide is discharged through the drain pipe 32. The compressor refrigeration unit 33 can liquefy the carbon dioxide inside the collection tank 31 for easy storage and recycling. The operating door 34 allows easy opening of the filter box 14 to clean and replace the internal primary filter plate 15 and secondary filter plate 16 for better filtration. The sealing airbag 35 can deform and fit according to the size of the gas storage tank to ensure better sealing between the placement slot 4 and the gas storage tank, thus ensuring the recovery rate of residual gas.
