Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide dehumidification, and particularly to a carbon dioxide energy storage drying and acid removal device and an energy storage air film. Background Art

[0002] A carbon dioxide energy storage device is an energy storage system that uses carbon dioxide as an energy carrier. Its basic principle is to store carbon dioxide through compression, liquefaction or other means, and then release it when needed, and convert the stored energy into available electrical energy or other forms of energy through corresponding technical means (such as expansion, power generation, etc.). Carbon dioxide energy storage technology belongs to a new energy storage technology and has great development potential, especially having certain advantages in solving the problems of volatility and instability of renewable energy.

[0003] In the patent with the publication number CN118934761A, an air dehumidification system for compressed carbon dioxide energy storage is disclosed, belonging to the field of compressed carbon dioxide energy storage, including a gas storage module, an energy storage module, a dehumidification module, and an energy release module; the gas storage module is used to store the gaseous carbon dioxide after energy release by the energy release module, the energy storage module is used to liquefy and store the gaseous carbon dioxide discharged from the gas storage module, the energy release module is used to release energy from the energy storage module, and the dehumidification module is used to dehumidify the air entering the gas storage module by using the gaseous carbon dioxide compressed and cooled by the energy storage module.

[0004] The existing technology has the following defects:

[0005] Carbon dioxide storage has requirements for humidity because carbon dioxide containing water vapor will produce acid, which will corrode pipelines, compression or energy release equipment, turbine generators, etc. It is difficult to achieve a balance among cost, energy consumption, and dehumidification effect in the existing technology. For example, although the condensation method has a low cost, its effect is limited; the adsorption method has a good effect but a high operating cost. Therefore, a carbon dioxide dehumidification device with high efficiency, low energy consumption, adaptability, and economy is needed to adapt to the dehumidification and acid removal during carbon dioxide energy storage. Summary of the Invention

[0006] In view of the above problems existing in the prior art, a carbon dioxide energy storage drying and acid removal device and an energy storage air film are proposed.

[0007] One aspect of the present application provides a carbon dioxide energy storage drying and acid removal device, and its purpose is to: dry carbon dioxide in multiple stages during the carbon dioxide energy storage and energy release processes; and at the same time, control the humidity of carbon dioxide.

[0008] The technical solution of the present invention is as follows: A carbon dioxide energy storage drying and acid removal device includes a tank body and a tank cover arranged on the top of the tank body, and further includes a first partition plate arranged inside the tank body and a second partition plate arranged below the first partition plate. An air outlet pipe communicating with the tank body is arranged above the first partition plate. A first partition cylinder is arranged below the second partition plate. A third partition plate is arranged at the bottom of the first partition cylinder. An air inlet pipe communicating with the tank body is arranged below the second partition plate. The air inlet pipe is tangent to the inner wall of the tank body. A spiral partition plate is arranged between the first partition cylinder and the inner wall of the tank body. A liquid outlet is arranged at the bottom of the tank body. An adsorption component is arranged in the cavity formed between the upper part of the first partition plate and the tank body. A water filtration component is arranged in the cavity formed by the second partition plate, the third partition plate and the first partition cylinder;

[0009] Carbon dioxide gas enters the tank body through the air inlet pipe, enters the bottom of the tank body through the spiral channel formed by the spiral partition plate, and then flows out through the water filtration component and the adsorption component and finally through the air outlet pipe.

[0010] By adopting the above scheme, carbon dioxide passes through the spiral partition plate, the water filtration component and the adsorption component in sequence. Liquid water and acid liquid are removed through centrifugal dehydration and the water filtration component, and water vapor is removed through the adsorption component, so as to dry carbon dioxide during the energy storage and energy release processes of carbon dioxide; at the same time, the humidity of carbon dioxide is controlled to improve the stability of carbon dioxide storage.

[0011] Further, the water filtration component includes a plurality of first through holes arranged on the second partition plate, second through holes arranged on the third partition plate corresponding to the positions of the first through holes, a water draining cover arranged at the orifice below the second through holes, and a water filtration column arranged at the first through holes and extending into the water draining cover. The water filtration column is made of a hydrophobic material.

[0012] By adopting the above scheme, through the setting of the water filtration component, liquid water droplets are blocked by the water filtration column, and are collected and dripped to the bottom of the tank body from the outer wall of the water filtration column, so that carbon dioxide enters the adsorption component through the water filtration column to further remove gaseous water.

[0013] Further, a pair of C-shaped flow blocking covers are arranged on the outer side of each water filtration column, and the bottom of the water filtration column is set to be sharp.

[0014] By adopting the above scheme, through the setting of a pair of C-shaped flow blocking covers, vertical air flow is formed on the outer wall of the water filtration column by carbon dioxide, the contact effect between carbon dioxide and the water filtration column is increased, and the dehumidification and acid removal efficiency are improved. By setting the bottom of the water filtration column to be sharp, it is beneficial for acid liquid to be collected at the bottom of the water filtration column and then drip.

[0015] Further, the adsorption assembly includes a plurality of through holes three provided on the first partition plate, an adsorption shell provided at the opening of the through hole three and extending to the can cover, a ventilation pipe is provided at the center of each adsorption shell and extends below the first partition plate, a sealing plate is provided between the bottom surface of the adsorption shell and the ventilation pipe, and adsorption particles are filled between the adsorption shell and the ventilation pipe.

[0016] With the above solution, by setting the adsorption assembly, carbon dioxide reacts with the adsorption particles in the adsorption shell through the ventilation pipe, further removing the gaseous water in the carbon dioxide to prevent the water vapor from liquefying again and reacting chemically with the carbon dioxide.

[0017] Further, the cross-section of the spiral partition plate is inclined towards the inner wall of the tank body.

[0018] With the above solution, by the inclined setting of the spiral partition plate, the acid liquid on the spiral partition plate is collected on one side close to the tank body, which is beneficial to the downward discharge of the acid liquid.

[0019] Further, a second partition cylinder is provided below the second partition plate. A water filtration cavity is formed between the second partition cylinder and the tank body. A plurality of water drainage holes one are provided at the bottom of the second partition cylinder. The spiral partition plate is arranged between the first partition cylinder and the second partition cylinder. A plurality of liquid blocking plates are equidistantly spaced above the spiral partition plate. The liquid blocking plates are inclined in the opposite direction of the airflow. Drainage holes two corresponding to the positions of the plurality of liquid blocking plates are formed on the second partition cylinder. The drainage holes two are arranged at the included angle between the liquid blocking plate and the spiral partition plate and on the side close to the inner wall of the tank body.

[0020] With the above solution, by setting a plurality of liquid blocking plates and corresponding drainage holes two, the acid liquid collected on the spiral partition plate enters the water filtration cavity through the drainage holes two, and then is collected at the bottom of the tank body through the drainage holes one, shortening the path of the acid liquid collection and discharge. The short path can accelerate the discharge of the acid liquid, improve the operation efficiency of the system, and ensure the continuity and stability of the acid removal process.

[0021] Further, the upper edge of the liquid blocking plate is set as a concave arc edge and a plurality of drag reduction holes are provided on the liquid blocking plate.

[0022] With the above solution, through the concave arc edge and the drag reduction holes, the flow resistance of carbon dioxide in the spiral channel is reduced.

[0023] Further, a threaded post is provided on the can cover, a bracket is provided on the tank body, a nut is provided on the bracket, and the nut is matched with the threaded post

[0024] With the above solution, by setting the threaded post and the nut, it is used to lift and open the can cover so as to replace the adsorption assembly.

[0025] Another aspect of the present application provides a carbon dioxide energy storage air film, which is connected to a carbon dioxide energy storage drying and acid removal device, and includes a lower structure, an outer film, and an inner gas storage bladder. Two ventilation holes are provided on the lower structure, one of which is connected to the intake pipe of a carbon dioxide energy storage drying and acid removal device, and the other is connected to the outlet pipe of another carbon dioxide energy storage drying and acid removal device.

[0026] With the above solution, by arranging two carbon dioxide energy storage drying and acid removal devices in the air outlet and intake channels, carbon dioxide can be dried during both the carbon dioxide energy storage and release processes; at the same time, the humidity of carbon dioxide is controlled.

[0027] Beneficial effects of the present invention:

[0028] Enable carbon dioxide to pass through the spiral partition plate, water filtration component, and adsorption component in sequence. Liquid water and acid liquid are removed through centrifugal dehydration and the water filtration component, and water vapor is removed through the adsorption component, so as to dry carbon dioxide during the carbon dioxide energy storage and release processes; at the same time, the humidity of carbon dioxide is controlled to improve the stability of carbon dioxide storage.

[0029] By arranging a plurality of liquid blocking plates and corresponding drain holes II, the acid liquid collected by the spiral partition plate enters the water filtration cavity through the drain holes II, and then is collected at the bottom of the tank body through the drain holes I, shortening the path of acid liquid collection and discharge. The short path can accelerate the discharge of acid liquid, improve the operation efficiency of the system, and ensure the continuity and stability of the acid removal process.

Specific embodiments

[0042] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0043] Example 1, referring to 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 provided on the top of the tank body 1, and further including a first partition board 3 provided inside the tank body 1 and a second partition board 4 provided below the first partition board 3. An air outlet pipe 5 communicating with the tank body 1 is provided above the first partition board 3, a first partition cylinder 6 is provided below the second partition board 4, a third partition board 7 is provided at the bottom of the first partition cylinder 6, an air inlet pipe 8 communicating with the tank body 1 is provided below the second partition board 4, the air inlet pipe 8 is tangent to the inner wall of the tank body 1, a spiral partition board 9 is provided between the first partition cylinder 6 and the inner wall of the tank body 1, a liquid outlet 10 is provided at the bottom of the tank body 1, an adsorption assembly is provided in the cavity formed between the upper part of the first partition board 3 and the tank body 1, and a water filtering assembly is provided in the cavity formed by the second partition board 4, the third partition board 7 and the first partition cylinder 6; the 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 board 9, and then flows out through the water filtering assembly and the adsorption assembly and finally through the air outlet pipe 5.

[0044] 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 provided at the lowest point of the tank body 1, and there is a valve 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 air flow and the water separation effect. 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.

[0045] Referring to Figures 2-3 , the water filtration component includes a plurality of through holes one 11 provided on the partition plate two 4, through holes two 12 provided on the partition plate three 7 corresponding to the positions of the through holes one 11, a water draining cover 13 provided at the orifice below the through holes two 12, and a water filtration column 14 provided at the through holes one 11 and extending into the water draining cover 13. The water filtration column 14 is made of a hydrophobic material.

[0046] Specifically, the upper end of the water filtration column 14 is open and communicates with the through hole one 11, and the lower end is closed. The water filtration column 14 is set to be long columnar to improve the water filtration effect. A fluorinated polymer coating is used on the water filtration column 14, which has extremely strong hydrophobicity and can effectively isolate moisture.

[0047] By setting the water filtration component, the liquid water droplets are blocked by the water filtration column 14 and collect and drip from the outer wall of the water filtration column 14 to the bottom of the tank body 1, allowing carbon dioxide to enter the adsorption component through the water filtration column 14 to further remove gaseous water.

[0048] Referring to Figure 3 , a pair of C-shaped flow blocking covers 15 are provided on the outer side of each water filtration column 14, and the bottom of the water filtration column 14 is set to be sharp.

[0049] Specifically, a pair of flow blocking covers 15 are twisted and wound in the vertical direction, and a spiral cavity is formed inside the pair of flow blocking covers 15. When carbon dioxide enters the flow blocking covers 15, it will spiral upward, increasing the air flow speed to improve the filtration rate.

[0050] By setting a pair of C-shaped flow blocking covers 15, vertical air flow is formed on the outer wall of the water filtration column 14 for carbon dioxide, increasing the contact effect between carbon dioxide and the water filtration column 14 and improving the dehumidification and deacidification efficiency. By setting the bottom of the water filtration column 14 to be sharp, it is beneficial for the acid liquid to collect at the bottom of the water filtration column 14 and then drip.

[0051] Referring to Figure 2 and Figure 4, the adsorption assembly includes a plurality of through holes three 16 provided on the first partition plate 3, an adsorption shell 17 provided at the opening of the through hole three 16 and extending to the tank cover 2. A ventilation pipe 18 is provided at the center of each adsorption shell 17 and the ventilation pipe 18 extends below the first partition plate 3. A sealing plate 19 is provided 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.

[0052] Specifically, both the ventilation pipe 18 and the adsorption shell 17 adopt a porous structure. The ventilation pipe 18 penetrates through the adsorption shell 17 so that after carbon dioxide enters through the ventilation pipe 18, it can fully contact the adsorption particles 20. The adsorption particles 20 are made of silica gel or zeolite. These materials have strong moisture absorption ability and can adsorb water vapor in carbon dioxide gas.

[0053] By setting the adsorption assembly, carbon dioxide reacts with the adsorption particles 20 in the adsorption shell 17 through the ventilation pipe 18 to further remove the gaseous water in the carbon dioxide, so as to prevent the water vapor from liquefying again and generating a chemical reaction with the carbon dioxide.

[0054] Refer to Figure 7 , the cross-section of the spiral partition plate 9 inclines towards the inner wall of the tank body 1.

[0055] By arranging the spiral partition plate 9 in an inclined manner, the acid liquid on the spiral partition plate 9 is collected towards the side close to the tank body 1, which is beneficial for the acid liquid to drain downward.

[0056] Refer to Figure 2 and Figures 5-8 , a second partition cylinder 21 is provided below the second partition plate 4. A water filtering cavity 22 is formed between the second partition cylinder 21 and the tank body 1. A plurality of water draining holes one 23 are provided at the bottom of the second partition cylinder 21. The spiral partition plate 9 is arranged between the first partition cylinder 6 and the second partition cylinder 21. A plurality of liquid blocking plates 24 are equidistantly spaced above the spiral partition plate 9. The liquid blocking plates 24 incline in the direction opposite to the gas flow. Drainage holes two 25 corresponding to the positions of the plurality of liquid blocking plates 24 are formed on the second partition cylinder 21.

[0057] Specifically, the liquid blocking plates 24 incline in the direction opposite to the carbon dioxide gas flow. A clamping cavity is formed between the liquid blocking plates 24 and the spiral partition plate 9. Since the cross-section of the spiral partition plate 9 inclines towards the inner wall of the tank body 1, the side of the clamping cavity close to the second partition cylinder 21 is the lowest point. Therefore, the drainage holes two 25 are arranged at the included angle between the liquid blocking plates 24 and the spiral partition plate 9 and on the side close to the inner wall of the tank body 1, so that the acid liquid detained by the liquid blocking plates 24 can quickly flow into the water filtering cavity 22 through the drainage holes two 25, avoiding the situation that due to the long spiral partition plate 9, the collection path of some acid liquid is too long. The shorter the residence time of the acid liquid in the system, the less the accumulated acid amount, thus avoiding the risk of problems such as blockage and corrosion caused by the long-term stay of the acid liquid in pipelines or equipment.

[0058] By setting a plurality of liquid-blocking plates 24 and corresponding second drain holes 25, the acid liquid gathered by the spiral partition plate 9 enters the water filtering cavity 22 through the second drain holes 25, and then gathers at the bottom of the tank body 1 through the first drain holes 23, shortening the path of gathering and discharging the acid liquid. The short path can accelerate the discharge of the acid liquid, improve the operation efficiency of the system, and ensure the continuity and stability of the acid removal process.

[0059] Referring to Figure 6 , the upper edge of the liquid-blocking plate 24 is set as a concave arc edge 26, and a plurality of drag reduction holes 27 are arranged on the liquid-blocking plate 24.

[0060] Through the concave arc edge 26 and the drag reduction holes 27, the flow resistance of carbon dioxide in the spiral channel is reduced.

[0061] Referring to Figure 1 , a threaded post 28 is arranged on the tank cover 2, a bracket 29 is arranged on the tank body 1, and a nut 30 is arranged on the bracket 29. The nut 30 is matched with the threaded post 28.

[0062] By setting the threaded post 28 and the nut 30, the tank cover 2 can be lifted and opened 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 various 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.

[0063] During the use process, carbon dioxide is successively passed through the spiral partition plate 9, the water filtering assembly, and the adsorption assembly. Liquid water and acid liquid are removed through centrifugal dehydration and the water filtering assembly, and water vapor is removed through the adsorption assembly, so as to dry the carbon dioxide during the energy storage and energy release processes of carbon dioxide; at the same time, the humidity of carbon dioxide is controlled to improve the storage stability of carbon dioxide.

[0064] Example 2, referring to Figure 9 , which is the second embodiment of the present invention, provides a carbon dioxide energy storage gas film, which is connected to the carbon dioxide energy storage drying and acid removal device, and includes a lower structure 31, an outer film 32, and a gas storage inner bag 33. Two ventilation holes are arranged on the lower structure 31. One ventilation hole is connected to the intake pipe 8 of a carbon dioxide energy storage drying and acid removal device, and the other ventilation hole is connected to the outlet pipe 5 of another carbon dioxide energy storage drying and acid removal device.

[0065] Specifically, the lower structure 31 is the basic structure of the carbon dioxide energy storage air film system, which is used to support the entire air film system, ensure the stability of the gas storage inner bladder 33 and the tension of the outer membrane 32, provide sufficient support force and durability, and withstand the stress caused by the high or low pressure changes in the air film system. The lower structure 31 is usually designed to be circular or square, and can also be of other shapes, with the function of adapting to air film 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 air film energy storage system, which is mainly used to wrap the gas storage inner bladder 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 the 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 bladder 33, and can be connected by welding or hot pressing technology to ensure the reliable sealing of each unit connection part of the outer membrane 32. The gas storage inner bladder 33 is the core part for storing carbon dioxide gas. It stores and releases gas by expanding and contracting to achieve energy storage and release. High-pressure resistant materials are used, such as high-strength PVDF film materials, which have excellent aging resistance and high-pressure resistance, and can withstand the compression and expansion of gas during storage. The gas storage inner bladder 33 is usually deformable, designed in the shape of an airbag, and inflated or deflated as needed. In order to cope with the gas pressure change, the inner bladder needs to be designed with good airtightness, water vapor barrier and high elasticity to ensure the smooth progress of the gas storage and release process.

[0066] By setting two carbon dioxide energy storage drying and acid removal devices in the air outlet and air inlet channels, the drying of carbon dioxide can be carried out during both the carbon dioxide energy storage and energy release processes; at the same time, the humidity of carbon dioxide is controlled.

[0067] Example 3, referring to Figure 10 , is the third embodiment of the present invention, which provides a carbon dioxide air film energy storage system. The carbon dioxide air film energy storage system stores and releases energy through compression and expansion processes. Each part of the equipment, including the low-pressure carbon dioxide storage tank, high-pressure storage tank, heat storage tank, cold storage tank, cooler, heater, compressor, and expander, works together to ensure efficient energy conversion and storage. The compressor and expander are respectively responsible for energy storage and release, and the heat and cold energy management system optimizes the energy conversion efficiency to ensure the stable operation of the system. The carbon dioxide energy storage drying and acid removal device in the first embodiment of the present invention is specifically arranged at two positions, one position is between the compressor and the energy storage air film, and the other position is between the expander and the energy storage air film. The drying of carbon dioxide can be carried out during both the carbon dioxide energy storage and energy release processes; at the same time, a humidity detection sensor and a pressure detection sensor are arranged in the drying device, so as to facilitate the control of the humidity of carbon dioxide.

[0068] Energy storage process (charging stage):

[0069] 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. At the same time as compression, the heat is transferred to the heat storage tank for storage. The compressed high-pressure carbon dioxide gas is cooled by a cooler and finally stored in the high-pressure carbon dioxide storage tank.

[0070] Energy release process (discharge stage):

[0071] 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 a generator or other equipment. During the expansion process, the gas temperature drops, and part of the cold energy can be stored in the cold storage tank. If further adjustment of the expansion temperature is required, a heater can be used to appropriately heat the gas.

[0072] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
