Description

Technical Field

[0001] This utility model belongs to the field of carbon dioxide capture technology, specifically relating to a carbon dioxide capture and storage device. Background Technology

[0002] Carbon dioxide capture technology is used to remove carbon dioxide from gas streams or separate it as a gaseous product. Capture is the first step in carbon capture and storage. Carbon dioxide needs to be present in a high purity during transportation and storage, but in most cases, the concentration of carbon dioxide in industrial exhaust gas does not meet this requirement. Therefore, carbon dioxide must be separated from the exhaust gas; this process is called carbon dioxide capture. Carbon dioxide capture technologies can be divided into several categories, including chemical absorption, physical absorption, physical adsorption, membrane separation, and cryogenic separation. The selection of capture methods and equipment needs to be based on the actual characteristics and parameters of the carbon dioxide emission source.

[0003] After carbon dioxide is captured, it needs to be transported to a storage tank for storage. However, the existing storage device only has one storage station during use. Therefore, after the storage tank is sealed, the machine needs to be stopped to replace the storage tank and then restarted. The start-up and shutdown operations waste a lot of time, are inefficient, and have certain limitations in use. Utility Model Content

[0004] The purpose of this invention is to provide a carbon dioxide capture and storage device to solve the problem mentioned in the background art that the existing storage devices only have one storage station when in use. Therefore, after the storage tank is sealed, it is necessary to stop the machine to replace the storage tank and then start the machine again. The start-up and shutdown operations waste a lot of time, have low efficiency, and have certain limitations in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon dioxide capture and storage device, comprising a frame, on which a collection cylinder and two placement cylinders are fixedly mounted. An air inlet pipe is installed through the outer surface of the collection cylinder. A screen is detachably installed inside the collection cylinder. A collection cylinder cover is threaded onto the top of the collection cylinder. A three-way pipe is installed through the upper surface of the collection cylinder cover. Solenoid valves are provided at both ends of the three-way pipe, and connecting hoses are connected to both ends of the three-way pipe. A storage tank is inserted into the placement cylinder. The storage tank and the connecting hoses are detachably connected. A support plate is movably arranged inside the placement cylinder. The bottom end of the storage tank is in contact with the surface of the support plate. An mounting plate is movably arranged inside the placement cylinder. A contact switch is fixedly installed on the upper surface of the mounting plate. The contact switch is located on the lower surface of the support plate and is electrically connected to the solenoid valve.

[0006] The above solution utilizes a three-way pipe with a connecting hose. The three-way pipe has two solenoid valves. When one of the storage tanks stores carbon dioxide, it drives the support plate downwards. Once the required storage level is reached, the support plate touches a contact switch, which in turn closes the corresponding solenoid valve and opens the other solenoid valve. This dual-station storage tank setup allows for tank replacement without stopping the machine, effectively improving work efficiency. The height of the contact switch is adjustable, allowing for adaptive use based on the weight of carbon dioxide to be stored, enhancing versatility. A collection cylinder with a screen filters the collected carbon dioxide, preventing unwanted impurities from being transported and stored, achieving excellent screening results. A motor-driven cleaning brush cleans the screen, preventing clogging.

[0007] In the above scheme, it should be noted that the motor is electrically connected to an external power supply.

[0008] In a preferred embodiment, the inner wall of the collection cylinder is detachably mounted with a mounting bracket by bolts, a motor is fixedly mounted on the mounting bracket, and a cleaning brush is fixedly mounted on the end of the output shaft of the motor, with the bristles of the cleaning brush adhering to the lower surface of the screen.

[0009] The above solution utilizes a mounting bracket in conjunction with a motor and a cleaning brush. The mounting bracket secures the motor, and the cleaning brush rotates under the motor's drive to clean the screen and prevent clogging.

[0010] In a preferred embodiment, a clamping ring is fixed to the inner wall of the collecting cylinder cover, the clamping ring is fitted and arranged on the upper surface of the screen, a plurality of inserts are fixed to the inner wall of the collecting cylinder, the inserts are fitted on the lower surface of the screen, and a plurality of alignment rods are fixed to the lower surface of the screen, the alignment rods and inserts are used in conjunction.

[0011] Using the above method, the alignment rod is inserted into the sleeve, and the clamping ring is used to press the screen to achieve the installation of the screen and prevent the screen from shaking or moving.

[0012] In a preferred embodiment, a plurality of sliding rods are fixed to the inner wall of the placement cylinder, and a spring is sleeved on the outside of the sliding rod. The bearing plate is slidably mounted on the outer surface of the sliding rod, and the two ends of the spring are fixedly connected to the bearing plate and the inner wall of the placement cylinder, respectively.

[0013] By adopting the above scheme, the sliding rod is used to support the up and down movement of the support plate, thereby improving the stability of the movement. When carbon dioxide is stored in the storage tank, it will drive the support plate to move downward, which in turn drives the spring to deform. Thus, after the storage tank is removed, the elasticity of the spring can be used to drive the support plate to move upward quickly to reset, improving the convenience of operation.

[0014] In a preferred embodiment, a threaded rod is threadedly installed on the lower surface of the placement cylinder, a knob is fixedly installed at the bottom end of the threaded rod, the top end of the threaded rod is rotatably connected to the mounting plate, and telescopic rods are fixed on both sides of the threaded rod, with the two ends of the telescopic rods being fixedly connected to the mounting plate and the inner wall of the placement cylinder, respectively.

[0015] Using the above solution, a knob is used to drive the threaded rod to rotate, thereby driving the mounting plate to move the contact switch up and down, realizing the adjustment of the position and height of the contact switch. It can be adapted to the weight of carbon dioxide to be sealed. The telescopic rod can support the up and down movement of the mounting plate, improve the movement stability of the mounting plate, and prevent shaking.

[0016] In a preferred embodiment, a locking sleeve is fixed to the outer surface of the placement cylinder, a fixing sleeve is fixed to the outer surface of the placement cylinder cover, a locking rod is slidably inserted into the fixing sleeve, an operating disc is fixed to the top of the locking rod, and a spring is fixedly installed between the operating disc and the fixing sleeve. The locking rod and the locking sleeve are used in conjunction.

[0017] Using the above solution, after the cylinder cover is closed, the elasticity of spring two drives the locking rod to insert into the locking sleeve, thereby achieving a convenient locking operation for the cylinder cover.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This carbon dioxide capture and storage device uses a three-way pipe in conjunction with a connecting hose. The three-way pipe has two solenoid valves. When one of the storage tanks is storing carbon dioxide, it drives the support plate to move downward. When the required storage is reached, the support plate touches the contact switch, which in turn controls the corresponding solenoid valve to close and the solenoid valve on the other side to open. The dual-station storage tank setup allows for tank replacement without stopping the machine, effectively improving work efficiency. Furthermore, the height of the contact switch can be adjusted to adapt to the weight of carbon dioxide to be stored, improving its versatility.

[0020] This carbon dioxide capture and storage device uses a collection cylinder in conjunction with a screen to filter and screen the captured carbon dioxide, preventing unwanted impurities from being transported and stored, thus achieving a good screening effect. In addition, a motor drives a cleaning brush to rotate, which can clean the screen and prevent the mesh from becoming clogged. Attached Figure Description

Detailed Implementation

[0029] Please see Figure 1-7 This utility model provides a carbon dioxide capture and storage device, including a frame 1, on which a collection cylinder 2 and two placement cylinders 10 are fixedly installed. An air inlet pipe 3 is installed through the outer surface of the collection cylinder 2. A screen 4 is detachably installed inside the collection cylinder 2. A collection cylinder cover 5 is threadedly installed at the top of the collection cylinder 2. A three-way pipe 6 is installed through the upper surface of the collection cylinder cover 5. Solenoid valves 7 are provided at both ends of the three-way pipe 6, and connecting hoses 8 are connected to both ends of the three-way pipe 6. A storage tank 9 is inserted into the placement cylinder 10. The storage tank 9 is detachably connected to the connecting hose 8. A support plate 12 is movably installed inside the placement cylinder 10. The bottom end of the storage tank 9 is in contact with the surface of the support plate 12. An installation plate 13 is movably installed inside the placement cylinder 10. A contact switch 14 is fixedly installed on the upper surface of the installation plate 13. The contact switch 14 is located on the lower surface of the support plate 12 and is electrically connected to the solenoid valve 7.

[0030] By using a three-way pipe 6 in conjunction with a connecting hose 8, and with two solenoid valves 7 on the three-way pipe 6, when one of the sealing tanks 9 is sealing carbon dioxide, it will drive the support plate 12 to move downward. When the required sealing is achieved, the support plate 12 will touch the contact switch 14, which will then control the corresponding solenoid valve 7 to close and open the solenoid valve 7 on the other side. Thus, the dual-station sealing tank 9 setting allows for the replacement of the sealing tank 9 without stopping the machine, effectively improving work efficiency. The height of the contact switch 14 can be adjusted to adapt to the weight of carbon dioxide to be sealed, improving versatility. By using a collection cylinder 2 in conjunction with a screen 4, the collected carbon dioxide can be filtered and screened to prevent unwanted impurities from being transported and sealed, achieving a good screening effect. Furthermore, the cleaning brush 17 driven by the motor 15 can be rotated to clean the screen 4 and prevent the mesh from becoming clogged.

[0031] The inner wall of the collecting cylinder 2 is detachably mounted with a mounting bracket 16 by bolts. A motor 15 is fixedly mounted on the mounting bracket 16. A cleaning brush 17 is fixedly mounted on the end of the output shaft of the motor 15. The bristles of the cleaning brush 17 are closely arranged on the lower surface of the screen 4. The mounting bracket 16 is used in conjunction with the motor 15 and the cleaning brush 17 to fix the motor 15. The cleaning brush 17 rotates under the drive of the motor 15 to clean the screen 4 and prevent the mesh from clogging.

[0032] A clamping ring 18 is fixed to the inner wall of the collecting cylinder cover 5. The clamping ring 18 is attached to the upper surface of the screen 4. Several inserts 20 are fixed to the inner wall of the collecting cylinder 2. The inserts 20 are attached to the lower surface of the screen 4. Several alignment rods 19 are fixed to the lower surface of the screen 4. The alignment rods 19 and the inserts 20 are used together. The alignment rods 19 are inserted into the inserts 20, and the clamping ring 18 is used to press the screen 4 to achieve the installation of the screen 4 and prevent the screen 4 from shaking or moving.

[0033] Several sliding rods 21 are fixed to the inner wall of the placement cylinder 10. Springs 22 are sleeved on the outside of the sliding rods 21. The bearing plate 12 is slidably installed on the outer surface of the sliding rods 21. The two ends of the springs 22 are fixedly connected to the bearing plate 12 and the inner wall of the placement cylinder 10, respectively. The sliding rods 21 support the up and down movement of the bearing plate 12, thereby improving the stability of the movement. When carbon dioxide is stored in the sealing tank 9, it will drive the bearing plate 12 to move downward, which will in turn drive the springs 22 to deform. Thus, after the sealing tank 9 is removed, the elasticity of the springs 22 can be used to drive the bearing plate 12 to move upward and reset quickly, improving the convenience of operation.

[0034] A threaded rod 23 is threadedly installed on the lower surface of the placement cylinder 10. A knob is fixedly installed at the bottom end of the threaded rod 23. The top end of the threaded rod 23 is rotatably connected to the mounting plate 13. Telescopic rods 24 are fixed on both sides of the threaded rod 23. The two ends of the telescopic rods 24 are fixedly connected to the mounting plate 13 and the inner wall of the placement cylinder 10, respectively. The knob drives the threaded rod 23 to rotate, thereby driving the mounting plate 13 to move the contact switch 14 up and down, realizing the adjustment of the position and height of the contact switch 14. It can be adaptively adjusted according to the weight of carbon dioxide to be sealed. The telescopic rods 24 can support the up and down movement of the mounting plate 13, improve the movement stability of the mounting plate 13, and prevent shaking.

[0035] A locking sleeve 25 is fixed to the outer surface of the placement cylinder 10, and a fixing sleeve 26 is fixed to the outer surface of the placement cylinder cover 11. A locking rod 27 is slidably inserted into the fixing sleeve 26. An operating disc 28 is fixed to the top of the locking rod 27. A spring 29 is fixedly installed between the operating disc 28 and the fixing sleeve 26. The locking rod 27 and the locking sleeve 25 work together. After the placement cylinder cover 11 is closed, the elasticity of the spring 29 drives the locking rod 27 to insert into the locking sleeve 25, thereby realizing a convenient locking operation of the placement cylinder cover 11.

[0036] In use, activating the solenoid valve 7 on one side allows the captured carbon dioxide to be transported to the collection cylinder 2 via the inlet pipe 3. After passing through the screen 4, particulate impurities remain in the collection cylinder 2. The clean carbon dioxide is then transported to the corresponding storage tank 9 via the three-way pipe 6 and the connecting hose 8. The increased gravity of the storage tank 9 causes the support plate 12 to move downwards. When the support plate 12 touches the contact switch 14, the amount of carbon dioxide sealed on its surface reaches the required level. At this point, the contact switch 14 controls the solenoid valve 7 on the same side to close and the solenoid valve 7 on the other side to open. This allows for the sealing operation of the other sealing tank 9, enabling the replacement of sealing tank 9 without stopping the machine. When the screen 4 passes through the screen, the motor 15 drives the cleaning brush 17 to rotate, cleaning the screen 4 and preventing the mesh from clogging. At the same time, the position and height of the contact switch 14 can be adjusted according to the amount of carbon dioxide to be sealed. During adjustment, rotating the knob drives the threaded rod 23 to rotate, which in turn drives the mounting plate 13 and the contact switch 14 to move up and down, thereby adjusting the height position. When the screen 4 needs to be replaced and cleaned, rotate and remove the collection cylinder cover 5, and then remove the screen 4 upwards.
