[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figure 1-8 , which is the first embodiment of the present invention, provides a carbon dioxide energy storage drying and acid removal device, including a tank body 1 and a tank cover 2 arranged on the top of the tank body 1, and also includes a partition plate 1 3 arranged inside the tank body 1, a partition plate 2 4 arranged below the partition plate 1 3, an air outlet pipe 5 connected to the tank body 1 is arranged above the partition plate 1 3, a partition cylinder 1 6 is arranged below the partition plate 2 4, a partition plate 3 7 is arranged at the bottom of the partition cylinder 6, an air inlet pipe 8 connected to the tank body 1 is arranged below the partition plate 2 4, and an air inlet pipe 8 connected to the tank body 1 is arranged below the partition plate 2 4. The tube 8 is tangent to the inner wall of the tank body 1, a spiral partition plate 9 is arranged between the partition cylinder 6 and the inner wall of the tank body 1, a liquid outlet 10 is arranged at the bottom of the tank body 1, an adsorption component is arranged in the compartment formed above the partition plate 3 and the tank body 1, and a water filter component is arranged in the compartment formed by the partition plate 2 4, the partition plate 3 7 and the partition cylinder 6; carbon dioxide gas enters the tank body 1 through the air inlet pipe 8, enters the bottom of the tank body 1 through the spiral channel formed by the spiral partition plate 9, and then flows out from the air outlet pipe 5 through the water filter component and the adsorption component.

[0030] Specifically, the bottom of the tank body 1 is designed to be arc-shaped to facilitate the collection of acid liquid. At the same time, a liquid outlet 10 is set at the lowest point of the tank body 1, and a valve is provided at the liquid outlet 10 to facilitate the discharge of the collected acid liquid. In the design of centrifugal water removal using a spiral channel, the selection of the pitch needs to comprehensively consider the gas-liquid separation efficiency, fluid flow rate, pressure loss and the overall size of the equipment. The size of the pitch will directly affect the centrifugal force of the airflow and the effect of water separation. In this embodiment, the pitch of the spiral partition plate 9 can be reduced to 0.5 times the channel diameter to enhance the centrifugal force.

[0031] Reference Figure 2-Figure 3 The water filter assembly includes a plurality of through holes 11 arranged on the partition plate 4, a through hole 12 arranged on the partition plate 7 corresponding to the position of the through hole 11, a drain cover 13 arranged at the opening below the through hole 12, and a water filter column 14 arranged at the through hole 11 and extending into the drain cover 13, wherein the water filter column 14 is made of a hydrophobic material.

[0032] Specifically, the upper end of the water filter column 14 is an open connecting hole 11, and the lower end is a closed end. The water filter column 14 is configured as a long column to improve the water filtering effect. The water filter column 14 is coated with a fluorinated polymer, which has extremely strong hydrophobicity and can effectively isolate moisture.

[0033] By setting up the water filter assembly, liquid water droplets are blocked by the water filter column 14, collected by the outer wall of the water filter column 14 and dripped to the bottom of the tank body 1, so that carbon dioxide enters the adsorption assembly through the water filter column 14 to further remove gaseous water.

[0034] Reference Figure 3 A pair of C-shaped flow blocking covers 15 are arranged on the outside of each water filtering column 14, and the bottom of the water filtering column 14 is arranged to be sharp.

[0035] Specifically, a pair of spoilers 15 are twisted and wound in a vertical direction, and a spiral cavity is formed in the pair of spoilers 15. When carbon dioxide enters the spoiler 15, it will spiral upward, increasing the air flow speed to improve the filtration rate.

[0036] By setting a pair of C-shaped baffles 15, carbon dioxide forms a vertical airflow on the outer wall of the water filter column 14, increasing the contact effect between carbon dioxide and the water filter column 14, and improving the dehumidification and acid removal efficiency. By setting the bottom of the water filter column 14 to a sharp shape, the acid is facilitated to gather at the bottom of the water filter column 14 and then drip.

[0037] Reference Figure 2 and Figure 4The adsorption assembly includes a plurality of through holes 16 arranged on the partition plate 3, an adsorption shell 17 arranged at the opening of the through hole 16 and extending to the tank cover 2, a ventilation pipe 18 is arranged at the center of each adsorption shell 17 and the ventilation pipe 18 extends to the bottom of the partition plate 3, a sealing plate 19 is arranged between the bottom surface of the adsorption shell 17 and the ventilation pipe 18, and adsorption particles 20 are filled between the adsorption shell 17 and the ventilation pipe 18.

[0038] Specifically, the ventilation pipe 18 and the adsorption shell 17 both adopt a porous structure, and the ventilation pipe 18 runs through the adsorption shell 17 so that carbon dioxide can fully contact with the adsorption particles 20 after entering through the ventilation pipe 18. The adsorption particles 20 are made of silica gel or zeolite. These materials have strong hygroscopic ability and can adsorb water vapor in the carbon dioxide gas.

[0039] By providing the adsorption assembly, the carbon dioxide reacts with the adsorption particles 20 in the adsorption shell 17 through the vent pipe 18, and the gaseous water in the carbon dioxide is further removed to prevent the water vapor from liquefying again and reacting chemically with the carbon dioxide.

[0040] Reference Figure 7 The cross section of the spiral partition plate 9 is inclined toward the inner wall of the tank body 1 .

[0041] The spiral partition plate 9 is tilted so that the acid liquid on the spiral partition plate 9 is gathered to the side close to the tank body 1, which is conducive to the downward discharge of the acid liquid.

[0042] Reference Figure 2 and Figure 5-Figure 8 A separation cylinder 21 is arranged below the separation plate 4, a water filter chamber 22 is formed between the separation cylinder 21 and the tank body 1, a plurality of drainage holes 23 are arranged at the bottom of the separation cylinder 21, a spiral separation plate 9 is arranged between the separation cylinder 1 6 and the separation cylinder 21, a plurality of liquid blocking plates 24 are arranged at equal intervals above the spiral separation plate 9, the liquid blocking plates 24 are inclined in the opposite direction of the airflow, and a plurality of drainage holes 25 corresponding to the positions of the plurality of liquid blocking plates 24 are opened on the separation cylinder 21.

[0043] Specifically, the liquid blocking plate 24 is inclined in the opposite direction to the carbon dioxide gas flow, and a cavity is formed between the liquid blocking plate 24 and the spiral partition plate 9. Since the cross section of the spiral partition plate 9 is inclined toward the inner wall of the tank body 1, the cavity is at the lowest point near the second partition tube 21. Therefore, the second drain hole 25 is arranged at the angle between the liquid blocking plate 24 and the spiral partition plate 9 and near the inner wall of the tank body 1, so that the acid retained by the liquid blocking plate 24 can quickly flow into the water filter chamber 22 through the second drain hole 25, avoiding the long distance for part of the acid to collect due to the long spiral partition plate 9. The shorter the retention time of the acid in the system, the less the amount of acid accumulated, thereby avoiding the acid staying in the pipeline or equipment for a long time, reducing the risk of blockage, corrosion and other problems.

[0044] By setting up multiple liquid-blocking plates 24 and corresponding drain holes 25, the acid liquid collected on the spiral partition plate 9 enters the water filter chamber 22 through the drain hole 25, and then collects to the bottom of the tank body 1 through the drain hole 1 23, shortening the distance for the acid liquid to be collected and discharged. The short path can accelerate the discharge of the acid liquid, improve the system operation efficiency, and ensure the continuity and stability of the acid removal process.

[0045] Reference Figure 6 The upper edge of the liquid-blocking plate 24 is configured as a concave arc edge 26 and a plurality of drag-reducing holes 27 are provided on the liquid-blocking plate 24 .

[0046] The concave arc edge 26 and the drag reducing holes 27 reduce the flow resistance of carbon dioxide in the spiral channel.

[0047] Reference Figure 1 A threaded column 28 is provided on the tank cover 2 , a bracket 29 is provided on the tank body 1 , a nut 30 is provided on the bracket 29 , and the nut 30 cooperates with the threaded column 28 .

[0048] The threaded column 28 and the nut 30 are provided to lift and open the can lid 2 so as to replace the adsorption particles 20 in the adsorption assembly. The adsorption particles 20 can be particles for adsorbing water vapor and can be made of a variety of materials. These materials have good hydrophilicity and a large surface area, can effectively adsorb and store water molecules, and are economical and efficient. Silica gel, activated alumina, and zeolite are common particles for adsorbing water vapor.

[0049] During use, carbon dioxide passes through the spiral partition plate 9, the water filtration component and the adsorption component in sequence, and liquid water and acid are removed by centrifugal dehydration and the water filtration component, and water vapor is removed by the adsorption component. In this way, carbon dioxide is dried during the carbon dioxide energy storage and release process; at the same time, the humidity of carbon dioxide is controlled to improve the stability of carbon dioxide storage.

[0050] Example 2, reference Fig. 9 , which is the second embodiment of the present invention, provides a carbon dioxide energy storage gas membrane, which is connected to a carbon dioxide energy storage drying and acid removal device, and includes a lower structure 31, an outer membrane 32, and an air storage inner bag 33. Two ventilation holes are provided on the lower structure 31, one of which is connected to an air inlet pipe 8 of a carbon dioxide energy storage drying and acid removal device, and the other ventilation hole is connected to an air outlet pipe 5 of another carbon dioxide energy storage drying and acid removal device.

[0051] Specifically, the lower structure 31 is the basic structure of the carbon dioxide energy storage gas membrane system, which is used to support the entire gas membrane system, ensure the stability of the gas storage inner capsule 33 and the tension of the outer membrane 32, provide sufficient support and durability, and withstand the stress caused by the high or low pressure changes in the gas membrane system. The lower structure 31 is usually designed to be round or square, or other shapes, and has the function of adapting to gas membrane systems of different sizes and shapes. The edge of the lower structure 31 can be designed to be embedded or fixedly connected to ensure the sealing of the system. The outer membrane 32 is the outer protective layer of the gas membrane energy storage system, which is mainly used to wrap the gas storage inner capsule 33, provide necessary physical isolation and support, and withstand the influence of the external environment. The outer membrane 32 also uses composite materials (such as polyester fiber reinforced polymer film) to improve wear resistance and tear resistance. The design form of the outer membrane 32 is usually customized according to the shape of the gas storage inner capsule 33, and can be connected by welding or hot pressing technology to ensure that the connection part of each unit of the outer membrane 32 is sealed reliably. The gas storage inner capsule 33 is the core part of storing carbon dioxide gas. It stores and releases gas by means of expansion and contraction to achieve energy storage and release. High-pressure resistant materials are used: such as high-strength PVDF membrane materials. These materials have excellent aging resistance and high-pressure resistance and can withstand the compression and expansion of gas during storage. The gas storage inner capsule 33 is usually deformable and designed in the shape of an airbag, and is inflated or deflated as needed. In order to cope with changes in gas pressure, the design of the inner capsule needs to have good air tightness, water vapor barrier and high elasticity to ensure smooth storage and release of the gas.

[0052] By arranging two carbon dioxide energy storage, drying and acid removal devices in the air outlet and air inlet channels, carbon dioxide can be dried during both the carbon dioxide energy storage and energy release processes; at the same time, the humidity of the carbon dioxide can be controlled.

[0053] Example 3, reference Fig.10 , which is the third embodiment of the present invention, provides a carbon dioxide gas film energy storage system, which stores and releases energy through compression and expansion processes. The various parts of the equipment, including low-pressure carbon dioxide storage tanks, high-pressure storage tanks, heat storage tanks, cold storage tanks, coolers, heaters, compressors, and expanders work together to ensure efficient energy conversion and storage. The compressor and expander are responsible for energy storage and release, respectively. The heat energy and cold energy management system optimizes the energy conversion efficiency and ensures stable operation of the system. The carbon dioxide energy storage, drying and acid removal device in Example 1 of the present invention is specifically arranged at two positions, one of which is between the compressor and the energy storage gas film, and the other is between the expander and the energy storage gas film. Carbon dioxide can be dried during the carbon dioxide energy storage and energy release process; at the same time, a humidity detection sensor and a pressure detection sensor are arranged in the drying device to facilitate the control of the humidity of carbon dioxide.

[0054] Energy storage process (charging phase): The low-pressure carbon dioxide gas enters the compressor from the low-pressure storage tank. After compression, the pressure of the carbon dioxide gas increases and heat is released. During compression, the heat is transferred to the heat storage tank for storage. The compressed high-pressure carbon dioxide gas is cooled by the cooler and finally stored in the high-pressure carbon dioxide storage tank.

[0055] Energy release process (discharge phase): High-pressure carbon dioxide gas is released from the high-pressure storage tank and enters the expander. During the expansion process, the internal energy of the gas is converted into mechanical energy to drive the generator or other equipment. During the expansion process, the gas temperature drops and part of the cold can be stored in the cold storage tank. If the expansion temperature needs to be further adjusted, the gas can be appropriately heated using a heater.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
