Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide storage, and more specifically, to a method and device for carbon dioxide storage. Background Art

[0002] With the acceleration of global industrialization, carbon dioxide emissions from human activities have increased dramatically. As a major greenhouse gas, carbon dioxide concentration in the atmosphere continues to rise, leading to global warming. Climate change has triggered a series of serious environmental problems, such as rising sea levels, frequent extreme climate events, and ecosystem destruction, posing a huge threat to human survival and development. Therefore, controlling carbon dioxide emissions and reducing its content in the atmosphere has become an urgent task facing the world.

[0003] At present, carbon dioxide storage is usually used to minimize carbon dioxide emissions into the atmosphere. There are usually three types of carbon dioxide storage methods: geological storage, mineral storage, and ocean storage. Mineral storage refers to the chemical reaction of carbon dioxide with metal oxides such as magnesium oxide to produce solid carbonates and other by-products. Since mineral storage can both store carbon dioxide and produce carbonates and other by-products, it has gradually become a hot topic for many researchers. In the prior art, a variety of devices for sealing carbon dioxide have also been developed. For example, the patent with the authorization announcement number CN114890171B discloses a device for sealing carbon dioxide with forsterite, including a sealing tank, a feed pipe port, a conveying mechanism and a storage box. The top of the sealing tank is equipped with a feed pipe port, and the top of the feed pipe port is equipped with a conveying mechanism. The outer wall of the conveying mechanism away from the sealing tank is equipped with a storage box, and the outer wall of the conveying mechanism close to the storage box is provided with a notch. A lower sliding frame is installed on one side of the outer wall of the storage box. The outer walls of both sides of the storage box are equipped with drive motors. The output ends of the two groups of the drive motors are equipped with crushing rollers through shafts, and the two groups of crushing rollers extend into the space inside the storage box. The two groups of crushing rollers are arranged up and down, and the bottom of the conveying mechanism is equipped with a support box. In the structure of the above patent, the reaction rate between forsterite and carbon dioxide is increased by crushing and stirring, thereby accelerating the generation of magnesium oxide compounds, and the transfer of its compounds is more convenient.

[0004] However, in actual use, when large-scale batch production is required, multiple such devices are usually set up to increase production. When there are multiple such devices, each device requires staff to manually feed forsterite into the space of the storage box when in use, and shuttle between the storage boxes of each device to feed the material. In large-scale production, the weight of forsterite raw materials required for each sealing tank is also large, which makes the staff's physical labor for feeding the material large and the production efficiency is reduced due to the long feeding time.

The receiving trough 2 can be made of high-strength, corrosion-resistant materials, such as stainless steel, to adapt to the friction of the raw material stone and the possible chemical corrosion environment; the receiving trough 2 can be rotatably mounted on the end of the rotating shaft away from the first driving member through a bearing to ensure that the receiving trough 2 can freely and smoothly perform circular motion with the rotating shaft in a horizontal plane; The raw material stone storage chamber 17 is built at a suitable high position, and the bottom of the raw material stone storage chamber 17 is connected to a feed pipe 18. The feed pipe 18 is made of a pipe with certain strength and wear resistance, such as a carbon steel lined ceramic pipe, to reduce the wear of the raw material stone during transportation; a valve is provided on the feed pipe 18, and the valve can be an electric ball valve to drive the feed pipe 18 to open or close the feed pipe 18; wherein, when the receiving trough 2 is driven by the first driving member to move to the position directly below the feed pipe 18, the valve on the feed pipe 18 is opened, and the raw material stone is stably transported to the receiving trough 2 through the feed pipe 18 under the action of gravity. In order to ensure the smooth transportation of the raw material stone, the inner diameter of the feed pipe 18 should be reasonably designed according to the maximum particle size of the raw material stone and the conveying flow rate to avoid blockage; The rotating shaft is provided with a second driving member, which can also be a motor, and is installed on the rotating shaft through a bracket. The driving end thereof is connected to the receiving trough 2 by a suitable connecting member, such as a flexible coupling, which can transmit torque and adapt to the rotation requirements of the receiving trough 2 in the vertical plane. The second driving member mainly turns the receiving trough 2 180 degrees from the state where the notch is facing upward to the state where the notch is facing downward. A plurality of conveying and lifting members are arranged below the receiving trough 2, and the plurality of conveying and lifting members are evenly distributed below the movement track of the receiving trough 2. The conveying and lifting members can select the existing auger elevator (screw feeder); a receiving port is arranged at one end of each conveying and lifting member, and a discharge port is arranged at the other end, and the receiving port is used to receive the falling raw material stone. Specifically, when the receiving trough 2 is driven by the first driving member to rotate to be located directly above one of the receiving ports, the second driving member drives the receiving trough 2 to flip 180 degrees, and then the raw material stone in the receiving trough 2 is put into the receiving port, and then the conveying and lifting member conveys the raw material stone, and the raw material stone is discharged from the discharge port; A high-temperature and high-pressure reactor 1 is provided on one side of each conveying and lifting member away from its receiving port, that is, there are multiple high-temperature and high-pressure reactors 1, and the high-temperature and high-pressure reactors 1 are supported on the ground or a supporting surface by installing a support frame 21. Multiple high-temperature and high-pressure reactors 1 correspond to multiple conveying and lifting members one by one. Each high-temperature and high-pressure reactor 1 is provided with a stone inlet, a water inlet, and a carbon dioxide inlet. The water inlet is connected to an external water source, and a stable water flow is provided by a water pump. The carbon dioxide inlet is connected to a carbon dioxide gas source, and the carbon dioxide intake pressure is controlled by a pressure regulating valve. The stone inlet of each high-temperature and high-pressure reactor 1 is connected to the discharge port of the corresponding conveying and lifting member, so that the conveying and lifting member can transport the raw stone to the corresponding high-temperature and high-pressure reactor 1; In this technical solution, when in use, the first driving member is started to drive the rotating shaft member to rotate, thereby making the receiving trough 2 do circular motion in the horizontal plane. When the receiving trough 2 moves to the bottom of the feeding pipe 18, the valve is opened, and the raw material stone falls into the receiving trough 2. Subsequently, the receiving trough 2 continues to move under the continuous drive of the first driving member. When it moves to the top of the receiving port of a certain conveying and lifting member, the second driving member is quickly started to drive the receiving trough 2 to rotate in the vertical plane so that its trough port is directly opposite to the receiving port. The raw material stone is put into the receiving port under the action of gravity, and then the screw conveyor lifts the raw material stone and transports it to the corresponding high-temperature and high-pressure reactor 1. This cycle is repeated until all reactors are filled with the required raw material stone. The beneficial effect obtained by adopting this technical solution is that a raw material stone conveying structure is provided by arranging a first driving member, a rotating shaft member, a material receiving trough 2, a raw material stone storage chamber 17, a material conveying pipe 18, a valve, a second driving member, a conveying and lifting member, a material receiving port, and a material discharge port. Through the mutual cooperation of the first driving member and the second driving member, it is convenient to convey the raw material stone to the reactors of each device, which greatly reduces manual labor and indirectly improves production efficiency. At the same time, multiple high-temperature and high-pressure reactors and multiple conveying and lifting members are arranged to provide a device for batch production of carbonates and other by-products, thereby expanding the production scale and production efficiency, providing a stable raw material supply guarantee for subsequent production processes, and having good application prospects.

[0021] In another technical solution, it also includes a base box 6 and a counterweight slot 11; the first driving member is a first motor 7, the first motor 7 is installed on the base box 6, and the output shaft of the first motor 7 is vertical; The rotating shaft member includes a horizontally arranged base plate 8 and a pair of mounting plates 19, wherein the base plate 8 is arranged above the base box 6, the middle part of the bottom of the base plate 8 is connected to the output shaft of the first motor 7, and the pair of mounting plates 19 are arranged on a pair of opposite side walls of the base plate 8, the pair of mounting plates 19 are parallel and opposite, and the two ends of the pair of mounting plates 19 extend out of the outside of the base plate 8 respectively; The material receiving trough 2 is arranged between two ends of a pair of mounting plates 19 in the same direction. The second driving member includes a second motor 12 and a connecting rod 13. The second motor 12 is installed on one of the mounting plates 19. The output shaft of the second motor 12 is coaxially connected with the connecting rod 13. The end of the connecting rod 13 away from the second motor 12 passes through the middle of the material receiving trough 2 and is rotatably connected to the other mounting plate 19, so that when the second motor 12 is started, the material receiving trough 2 is driven to rotate in a vertical plane. The counterweight trough 11 is arranged on the other end of the pair of mounting plates 19 away from the material receiving trough 2. In the above technical solution, the base box 6 is used to support and install the first driving member and the rotating shaft member. The shape of the base box 6 is determined according to the required number of reactors. For example, if there are four reactors, the base box 6 can be designed to be square or round. The first driving member is a first motor 7. The fixed end of the first motor 7 is installed on the base box 6. The output end of the first motor 7 is vertically upward, and the output end of the first motor 7 is connected to the rotating shaft member. The rotating shaft member includes a base plate 8 and a pair of mounting plates 19. The base plate 8 is horizontally arranged, and the middle part of the base plate 8 is fixedly connected to the output end of the first motor 7. The base plate 8 is provided with a mounting plate 19 on one of the opposite side walls. The two ends of the mounting plate 19 extend out of the corresponding ends of the base plate 8 respectively; a material receiving groove 2 is provided between one of the ends in the same direction of a pair of mounting plates 19, and a counterweight groove 11 is fixedly connected between the other ends in the same direction. The shape of the counterweight groove 11 can be a rectangular parallelepiped or a cylinder, and the size is determined comprehensively according to the required counterweight mass and the installation space. While ensuring the effective balance of the movement of the material receiving groove 2, the volume and weight of the counterweight groove 11 are minimized to reduce the overall load of the equipment. The counterweight groove 11 can be firmly installed on the other end of a pair of mounting plates 19 away from the material receiving groove 2 by welding or high-strength bolt connection, ensuring that it will not fall off during the long-term and high-intensity operation of the equipment, thereby ensuring the safety and stability of the equipment operation; The second driving member includes a second motor 12 and a connecting rod 13. The second motor 12 is installed on the protruding end of one of the mounting plates 19. Specifically, the second motor 12 is arranged on one of the mounting plates 19 on the side where the material receiving trough 2 is located, and is located on the side wall of the mounting plate 19 away from the other mounting plate 19. The output shaft of the second motor 12 is horizontally and coaxially connected with the connecting rod 13. The side wall of the material receiving trough 2 close to the second motor 12 and the other side wall opposite to the side wall are both provided with through holes. After the end of the connecting rod 13 away from the second motor 12 rotates and passes through the close mounting plate 19 (the close mounting plate 19 refers to the mounting plate 19 on which the second motor 12 is installed), it passes through a pair of through holes and then extends out of the material receiving trough 2. The connecting rod 13 is fixedly connected to the inner wall of the through hole, that is, the connecting rod 13 is fixedly connected to the material receiving trough 2, so that when the output shaft of the second motor 12 rotates, the material receiving trough 2 is driven to rotate through the connecting rod 13, thereby realizing the flipping of the material receiving trough 2. In this technical solution, when in use, a proper amount of counterweight is added to the counterweight trough 11 in advance to maximize the operating stability of the overall device; then the first motor 7 is started to cause the receiving trough 2 to move to the position just below the feeding pipe 18 to open the valve, and the raw material stone falls into the receiving trough 2. Subsequently, the receiving trough 2 continues to move under the continuous drive of the first motor 7. When it moves to the position above the receiving port of a certain conveying and lifting member, the second motor 12 is quickly started to drive the receiving trough 2 to rotate in the vertical plane so that its trough port is directly opposite to the receiving port, and the raw material stone is put into the receiving port under the action of gravity; The beneficial effect obtained by adopting this technical solution is that by setting the base box 6, the base plate 8, the mounting plate 19, the counterweight groove 11, the second motor 12, the first motor 7, and the connecting rod 13, a specific structure of the rotating shaft, the first driving member, and the second driving member is provided, which is convenient for assembly and use. At the same time, the counterweight groove 11 is set to facilitate balancing the movement of the material receiving trough 2, thereby improving the operating stability of the overall device.

[0022] In another technical solution, a partition plate 20 is horizontally provided in the base box 6, the mounting end of the first motor 7 is fixed on the partition plate 20, and the output end of the first motor 7 rotates through the top of the base box 6 and is fixedly connected to the base plate 8; a plurality of blanking holes 16 are opened on the side wall of the base box 6 below the partition plate 20, and an inlet and outlet door is also provided on the side wall of the base box 6, and the inlet and outlet door is located below the blanking holes 16; It also includes a plurality of inclined guide plates 14, which correspond to each other one by one, the plurality of conveying and lifting members, and the plurality of blanking holes 16. The high end of the guide plate 14 is connected to the corresponding conveying and lifting member and is located below the corresponding material receiving port, and the low end of the guide plate 14 is connected to the side wall of the base box 6 and is flush with the bottom wall of the corresponding blanking hole 16. In the above technical solution, a partition plate 20 is provided in the base box 6. The partition plate 20 is horizontally arranged to divide the interior of the base box 6 into a first area and a second area from top to bottom in sequence. The first area is used for installing the first motor 7. Specifically, the installation end of the first motor 7 is fixed on the partition plate 20, and the output shaft rotates out of the top of the first area (i.e., the top of the base box 6) and is fixedly connected to the bottom of the substrate 8. The second area is used for storing the dropped raw stones. Specifically, a plurality of blanking holes 16 are formed in the side wall of the second area. An inclined guide plate 14 is provided on each conveying and lifting member. The plurality of guide plates 14 correspond to the plurality of blanking holes 16 one by one. The high end of the guide plate 14 is located below the material receiving port, and the low end is connected to the side wall of the base box 6 where the corresponding blanking hole 16 is located. Moreover, the top of the low end of the guide plate 14 is flush with the inner bottom wall of the corresponding blanking hole 16, so that the raw stones dropped from the material receiving port can fall into the second area after passing through the guide plate 14 and the blanking hole 16. An access door is further provided on the base box 6. The access door is located below the blanking hole 16, so that when the amount of raw stones in the second area is too much and needs to be removed, the access door can be opened to remove the raw stones. In this technical solution, during use, when raw stones fall at the material receiving port, the raw stones falling on the guide plate 14 enter the second area through the guide plate 14 and the blanking hole 16 for temporary storage. By adopting this technical solution, the beneficial effect obtained is that by providing the partition plate 20, the guide plate 14, and the blanking hole 16, a structure for temporarily storing the dropped raw stones by using the base box 6 is provided. The layout and design are reasonable, which can avoid the waste of some raw stones and improve the practicability of the device.

[0023] In another technical solution, baffles 15 are provided at the other two ends of the guide plate 14. Specifically, the other two ends of the guide plate 14 refer to the other two ends except for the high end and the low end. The baffles 15 are provided at these two ends. The structure of the guide plate 14 and the two baffles 15 is similar to a U-shaped plate, which can prevent the raw stones from splashing out of the guide plate 14 due to the impact force when contacting the guide plate 14 after falling on the guide plate 14, further improving the practicability of the device.

[0024] In another technical solution, each conveying and lifting member includes a mounting seat 4, a receiving hopper 5, and a spiral feeding member 3. The receiving hopper 5 is installed on the mounting seat 4, and the spiral feeding member 3 is supported on the mounting seat 4. The port of the receiving end of the receiving hopper 5 forms the material receiving port. The area of the material receiving port is larger than the area of the notch of the receiving groove 2. When the receiving groove 2 moves to be located above the material receiving port, the receiving groove 2 rotates in the space directly above the receiving hopper 5, and the vertical center line of the receiving groove 2 is located on the side of the vertical center line of the receiving hopper 5 away from the guide plate 14, so that the end of the notch of the receiving groove 2 close to the guide plate 14 rotates towards the direction close to the receiving hopper 5 at the start of rotation, thereby reducing the situation where the raw stones fall out of the receiving range of the receiving hopper 5. The discharge end of the receiving hopper 5 is connected to the feed end of the spiral feeder 3, and the port of the discharge end of the spiral feeder 3 forms the discharge port, which is connected to the stone inlet of the corresponding high-temperature and high-pressure reactor 1; In the above technical solution, specifically, the conveying and lifting member includes a mounting seat 4, a material receiving hopper 5 and a spiral feeding member 3, the mounting seat 4 is a box structure, the material receiving hopper 5 is vertically arranged, an introduction hole is opened on the top of the mounting box, and the inner diameter of the bottom end of the material receiving hopper 5 is the same as the diameter of the introduction hole, so that the bottom end of the material receiving hopper 5 is coaxially arranged on the top of the mounting seat 4 where the introduction hole is located; the top port of the material receiving hopper 5 forms the material receiving port, and the area of ​​the material receiving hopper 5 is larger than the slot area of ​​the material receiving slot 2, so that the The receiving trough 2 can be turned over in the area just above the top port of the receiving hopper 5 to ensure that all the raw materials fall into the receiving hopper 5 as much as possible; when the receiving trough 2 moves to above any receiving hopper 5, the vertical center line of the receiving trough 2 is located on the side of the vertical center line of the receiving hopper 5 away from the base box 6, so that the end of the notch of the receiving trough 2 close to the guide plate 14 rotates toward the receiving hopper 5 when starting to rotate, which can avoid the situation where the raw materials escape from the receiving range of the receiving hopper 5 as much as possible, that is, further ensure that all the raw materials fall into the receiving hopper 5; The bottom of the introduction hole is coaxially connected with a guide tube 22; the spiral feeding member 3 includes an inclined and cylindrical mounting groove 301, a spiral feeding rod 304, a guide tube 22, and a driving motor 303. The lower end of the mounting groove 301 is the end where the groove bottom is located. The lower end of the mounting groove 301 penetrates the mounting seat 4 and then extends into the mounting seat 4. The mounting groove 301 is supported on the ground or a supporting surface by a supporting member. A driving motor 303 is installed at the bottom of the mounting groove 301. The output shaft of the driving motor 303 is coaxially connected with the spiral feeding rod 304. An entry hole is opened on the groove wall of the mounting groove 301.

Specifically, a partition is arranged in the installation groove 301, and the output shaft of the driving motor 303 rotates through the partition and is coaxially fixed with the spiral feeding rod 304; In the above technical scheme, during use, when the receiving trough 2 moves to a position above one of the receiving hoppers 5, the end of the slot of the receiving trough 2 close to the guide plate 14 is driven to rotate toward the receiving hopper 5 at the start of rotation, and the raw material stone is put into the receiving hopper 5. The raw material stone enters the mounting groove 301 through the receiving hopper 5, the guide hole, the guide tube 22, and the entry hole. Under the action of the spiral feeding rod 304, the raw material stone enters the corresponding high-temperature and high-pressure reactor 1 through the curved pipe 302 and the stone inlet.

[0026] The present invention also provides a carbon dioxide storage method, which uses the carbon dioxide storage device to store carbon dioxide, and specifically includes the following steps: S1, initial state, the receiving trough 2 is located directly below the feeding pipe 18, the valve is opened, the raw material stone in the raw material stone storage chamber 17 flows into the receiving trough 2 through the feeding pipe 18, and when the raw material stone in the receiving trough 2 reaches the required amount, the valve is closed; S2, start the first driving member to drive the material receiving trough 2 to move to the position just above the material receiving port of one of the conveying and lifting members; S3, simultaneously start the second driving member and the conveying and lifting member, the second driving member drives the receiving trough 2 to flip over until the notch is facing the receiving port, so that the raw material stone is put into the receiving port, and the conveying and lifting member transports and lifts the received raw material stone into the corresponding high-temperature and high-pressure reactor 1; when the raw material stone in the receiving trough is unloaded, start the second driving member again to drive the receiving trough 2 to flip over until the notch faces upward; S4, start the first driving member to drive the material receiving trough 2 to rotate to the position directly below the material conveying pipe 18; S5, repeating steps S1 to S4 until the required raw material stones are added into all high temperature and high pressure reactors 1; S6. For each high-temperature and high-pressure reactor 1, add a required amount of water from the water inlet, introduce a required amount of carbon dioxide from the carbon dioxide inlet, and then operate the reactor at the set temperature and pressure until the reaction is completed; In the above technical scheme, before the formal start of the carbon dioxide storage process, the entire device needs to be fully inspected and debugged to ensure that all components are firmly installed, such as the first drive member, the second drive member, the rotating shaft member, the material receiving trough 2, the conveying and lifting member, and the high-temperature and high-pressure reactor 1 are tightly connected without any signs of looseness; check that the line connection is normal, there is no risk of short circuit or circuit breakage, and ensure stable and reliable power supply; verify that the pipelines such as the feed pipe 18, the water inlet, and the carbon dioxide inlet are unobstructed, the valves are flexible to open and close, and the sealing is good to prevent the leakage of raw material stone, water and carbon dioxide; the raw material stone in the raw material stone storage chamber 17 is small granular raw material stone (large pieces of raw material stone are pre-crushed to form small granular raw material stone) to increase the contact area between the raw material stone and carbon dioxide, thereby increasing the reaction speed. The raw material stone can be a metal oxide such as basalt or forsterite, which is selected according to actual production; Initial feed (S1): Ensure that the device is in the initial state. At this time, the notch of the receiving trough 2 faces upward and is located directly below the feeding pipe 18. Open the valve on the feeding pipe 18. The raw material stone in the raw material stone storage chamber 17 flows steadily into the receiving trough 2 through the feeding pipe 18 under the action of gravity. In order to accurately control the amount of raw material stone added, a weight sensor can be pre-set in the receiving trough 2 and used in conjunction with an external control system. When it is monitored that the raw material stone in the receiving trough 2 reaches the required amount, quickly close the valve and stop feeding. For example, if each reaction requires 50kg of raw material stone, when the sensor feedback weight reaches 50kg, the control system immediately triggers the valve closing command; Transfer at receiving trough 2 (S2): The first driving member is started, and the first driving member drives the rotating shaft member to rotate, thereby driving the receiving trough 2 to perform circular motion along a predetermined trajectory in a horizontal plane, until the receiving trough 2 moves to the top of the receiving port of one of the conveying and lifting members, and is ready for the raw material stone unloading operation; Raw stone unloading and transportation (S3): At the same time, the second driving member and the conveying and lifting member are started. The second driving member drives the receiving trough 2 to quickly flip in the vertical plane until the notch is aligned with the receiving port. The raw material stone is smoothly put into the receiving port under the action of gravity. At the same time, the conveying and lifting member starts to work, and the spiral blades inside it rotate at a high speed to efficiently transport and lift the received raw material stone to the corresponding high-temperature and high-pressure reactor 1. When the raw material stone in the receiving trough is unloaded, the second driving member is started again to drive the receiving trough 2 to flip until the notch is facing upward, restore the initial state, and prepare for the next material receiving; Reset of receiving chute 2 (S4): Start the first driving member to drive the receiving trough 2 to move to the position directly below the conveying pipe 18, re-enter the initial feeding position, and prepare for the next round of raw material stone addition; Circulation feeding (S5): Repeat steps S1-S4 to add the required raw material stone to each high-temperature and high-pressure reactor 1 in turn until all high-temperature and high-pressure reactors have reached the set raw material stone filling amount; Carbon dioxide and water injection and reaction stage (S6) After the raw material stone is added, for each high-temperature and high-pressure reactor 1, turn on the water pump at the water inlet (the water inlet is connected to the external water supply device through a water supply pipeline, and a water pump is set on the water supply pipeline), add the required amount of water from the water inlet, and let it stand for 24 hours to allow the water to fully immerse the raw material stone. In actual use, a flow meter can be set on the water supply pipeline, and the flow meter can be used to accurately monitor the water injection volume in conjunction with an external control system. For example, a reactor needs to inject 1000L of water according to the reaction ratio. When the flow meter shows that the injection volume reaches 1000L, the water pump is automatically turned off; Then, the required amount of carbon dioxide is introduced from the carbon dioxide inlet; similarly, the carbon dioxide inlet can be connected to an air intake pipeline, which is connected to the carbon dioxide supply device, and a gas flow meter, a pressure regulating valve and an air pump are installed on the air intake pipeline, and an external control system is used to accurately control the intake amount and intake pressure of carbon dioxide to ensure the accuracy of the reaction conditions. The amount of carbon dioxide introduced is determined according to production requirements; After the addition of water and carbon dioxide is completed, the high-temperature and high-pressure reactor is operated at the set temperature and pressure; a temperature sensor and a pressure sensor are usually installed in the high-temperature and high-pressure reactor, and the temperature and pressure in the reactor are monitored in real time by the temperature sensor and the pressure sensor, and the feedback is fed to the control system, and the control system maintains the stability of the environment in the reactor by adjusting the heating device, the cooling device and the pressure release valve and other components until the reaction is completed; after the reaction is completed, the reactants are taken out for subsequent treatment after cooling and pressure relief according to conventional operations; The beneficial effect of adopting this technical solution is that it provides a carbon dioxide storage method. By converting the waste carbon dioxide into carbonates and other products through a reaction with metal oxides, not only the waste carbon dioxide is reused, but also the carbon dioxide is prevented from being discharged into the atmosphere, thereby reducing the burden of environmental governance.
