Description

Technical Field

[0001] The utility model belongs to the technical field of nitrogen separation, and particularly relates to a carbon-nitrogen separation pressurized reaction tank. Background Technique

[0002] In the carbon-nitrogen separation pressurized reaction tank, an adsorbent with selective adsorption ability for nitrogen or carbon-containing gases (such as carbon dioxide, carbon monoxide, etc.) is filled in the tank. Under pressurized conditions, one gas is preferentially adsorbed, while the other gas passes through the tank body, thereby achieving separation. The pressurization method can increase the partial pressure of oxygen in the mixed gas, which will cause more oxygen molecules to be adsorbed onto the activated carbon. The adsorption of nitrogen by carbon is very weak. Only under high temperature and high pressure, when using specially treated or carbon materials with specific structures, there may be a certain degree of adsorption, but this situation is relatively rare and the adsorption amount is usually small. Therefore, the carbon-oxygen separation pressurized tank can be used to separate oxygen from the air and extract nitrogen. When the existing carbon-nitrogen separation pressurized reaction tank increases the absorption amount of carbon for oxygen by pressurization, the pressure in the tank body will be relatively large. The nitrogen separated in the tank body is in the tank body under a certain pressure. When it is necessary to discharge the nitrogen in the pressurized tank body, the nitrogen is connected to the external pipeline, resulting in the connection between the tank body and the external space, generating decompression. After decompression occurs in the tank, the adsorbed oxygen molecules will desorb, thus separating from the carbon, affecting the separation effect of nitrogen and oxygen. Content of the Utility Model

[0003] The utility model provides a carbon-nitrogen separation pressurized reaction tank, which has the characteristic of solving the problem that when the separated nitrogen is discharged, the nitrogen is connected to the external pipeline, resulting in the connection between the tank body and the external space, generating decompression, and causing partial oxygen desorption to affect the extraction concentration of nitrogen.

[0004] The utility model provides the following technical solution: It includes a pressurized tank body and an adjustment box. The pressurized tank body and the adjustment box are connected by a connecting plate. A first motor is fixedly connected to the bottom end of the connecting plate. A rotating cylinder is fixedly connected to the driving end of the first motor. A plurality of carbon storage boxes are fixedly connected to the outer wall of the rotating cylinder. A sliding cylinder is slidably connected to the inner wall of the rotating cylinder. Communication holes that are interconnected are opened on the rotating cylinder, the carbon storage boxes, and the sliding cylinder. An adjustment plate is slidably connected to the inner wall of the adjustment box. A plurality of sliding plates are fixedly connected to the adjustment plate. Yield holes that match the sliding plates are opened on the connecting plate. The sliding plates are in contact with the carbon storage boxes.

[0005] Among them, a filter plate is opened on the outer wall of the carbon storage box. A limiting groove is fixedly connected to the top end of the sliding cylinder. A top plate is installed on the top of the pressurized tank body. The sliding cylinder penetrates through the top plate. A limiting ring is arranged above the top plate. A limiting block that matches the limiting groove is fixedly connected to the inner wall of the limiting ring.

[0006] Among them, a fixed rod is fixedly connected to the top end of the top plate, a connecting block is fixedly connected to the outer wall of the limiting ring, and the connecting block is slidably connected to the fixed rod.

[0007] Among them, a second motor is fixedly connected to the bottom end of the connecting plate, a threaded rod is fixedly connected to the driving end of the second motor, and the threaded rod is threadedly connected to the adjusting plate.

[0008] Among them, a limiting rod is fixedly connected between the connecting plate and the inner wall of the adjusting box, the limiting rod penetrates through the adjusting plate, and a circular hole for making way for the first motor is formed at the center of the adjusting plate.

[0009] The beneficial effect of the present utility model is that the first motor can drive the rotating cylinder and the carbon storage tank to rotate inside the pressure tank body, improving the extraction speed of carbon from oxygen. Then, the sliding plate fixedly connected to the adjusting plate can pass through the relief hole, so that while not affecting the pressurized state inside the pressure tank body, both sides of the carbon storage tank are closed. When discharging nitrogen, after the pressure inside the pressure tank body is reduced, it prevents the oxygen adsorbed on the carbon from desorbing and mixing into the nitrogen again, thereby ensuring the separation effect of the device on nitrogen.

[0010] Parts not involved in this device are the same as or can be implemented using existing technologies. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Please refer to Figures 1 - 4The utility model provides the following technical solutions: it includes a pressurized tank body 1 and a regulating box 13, the pressurized tank body 1 and the regulating box 13 are connected by a connecting plate 11, the bottom end of the connecting plate 11 is fixedly connected to a first motor 2, the driving end of the first motor 2 is fixedly connected to a rotating cylinder 21, the outer wall of the rotating cylinder 21 is fixedly connected to a plurality of carbon storage boxes 22, the inner wall of the rotating cylinder 21 is slidably connected to a slide cylinder 24, the rotating cylinder 21, the carbon storage box 22 and the slide cylinder 24 are all provided with interconnecting connecting holes 241, the inner wall of the regulating box 13 is slidably connected to an adjusting plate 32, a plurality of slide plates 33 are fixedly connected to the adjusting plate 32, a make way hole 12 matching the slide plate 33 is provided on the connecting plate 11, and the slide plate 33 fits with the carbon storage box 22.

[0017] In this implementation: The pressure tank body 1 is a tank for separating nitrogen in the air. After injecting air into the pressure tank body 1, the bottom and top of the pressure tank body 1 are respectively sealed by the connecting plate 11 and the top plate 25. The driving end of the first motor 2 fixedly connected to the bottom end of the connecting plate 11 penetrates into the pressure tank body 1 so that its driving end can be fixedly connected to the rotating cylinder 21. A number of carbon storage boxes 22 fixedly connected to the outer wall of the rotating cylinder 21 are used for storing and releasing the carbon that has absorbed oxygen. The carbon in the carbon storage box 22 is limited by it and is in direct contact with the air inside the pressure tank body 1. Since nitrogen is difficult to be adsorbed by the carbon, the carbon can absorb the oxygen in the air to separate oxygen from nitrogen. The pressure tank body 1 is a sealed tank, so that the pressure in its inner cavity can increase the pressure in the tank under the action of pressurization. Thus, in the pressurized state, the carbon can absorb more oxygen to ensure the separation effect of the oxygen in the air, thereby improving the separation concentration of nitrogen. When absorbing oxygen, the first motor 2 can be used to drive the rotating cylinder 21 to rotate, so that the carbon storage boxes 22 fixedly connected to the outer wall of the rotating cylinder 21 can rotate synchronously with it. Thus, the carbon can rotate in the inner cavity of the pressure tank body 1 in the carbon storage box 22, enabling the carbon to continuously contact the air to increase its oxygen absorption effect. However, when the pressure decreases after the oxygen absorbed under pressure, desorption will occur, causing the oxygen to mix with nitrogen again, affecting the separation concentration of nitrogen. At this time, the adjustment box 13 fixedly connected to the bottom end of the connecting plate 11 can be used. The adjustment box 13 is used for installing the adjustment plate 32 so that the adjustment plate 32 slides on the inner wall of the adjustment box 13. When it is necessary to take out the nitrogen from which oxygen has been separated, the adjustment plate 32 can be moved upward, driving the slide plate 33 fixedly connected to the top end of the adjustment plate 32 to move upward synchronously. The relief hole 12 opened on the connecting plate 11 is connected to the top of the slide plate 33. At this time, the top of the slide plate 33 can pass through the relief hole 12, enabling the slide plate 33 to fit on both sides of each carbon storage box 22 to close the carbon storage box 22, so that the carbon that has absorbed oxygen is between the slide plates 33 and will not contact the separated nitrogen. At this time, the sliding cylinder 24 slidably connected to the inner wall of the rotating cylinder 21 can be rotated to connect the communication holes 241, so that the carbon originally under pressure can contact the outside through the communication holes 241 and the sliding cylinder 24, enabling the desorbed oxygen to be discharged through the sliding cylinder 24. At the same time, after the nitrogen in the pressure tank body 1 is connected to the pipeline for extracting nitrogen, it can prevent the desorbed oxygen from the carbon from mixing with nitrogen again after the pressure changes, thereby ensuring the extraction concentration of nitrogen.

[0018] The outer wall of the carbon storage box 22 is provided with a filter plate 23. The top end of the sliding cylinder 24 is fixedly connected with a limiting groove 242. The top of the pressure tank body 1 is provided with a top plate 25. The sliding cylinder 24 penetrates through the top plate 25. Above the top plate 25, there is a limiting ring 26. The inner wall of the limiting ring 26 is fixedly connected with a limiting block 261 that matches the limiting groove 242. The filter plate 23 provided on the outer wall of the carbon storage box 22 is used to enable the air in the pressure tank body 1 to circulate on the carbon in the carbon storage box 22. The limiting groove 242 fixedly connected to the top end of the sliding cylinder 24 is used to correspond to the limiting ring 26 above the top plate 25, so that when the limiting block 261 fixedly connected to the inner wall of the limiting ring 26 is engaged with the communication hole 241, it can ensure that the communication holes 241 opened on the rotating cylinder 21, the carbon storage box 22 and the sliding cylinder 24 can be misaligned, ensuring that when the carbon absorbs air, the outside air can be blocked.

[0019] The top end of the top plate 25 is fixedly connected with a fixing rod 27. The outer wall of the limiting ring 26 is fixedly connected with a connecting block 262. The connecting block 262 is slidably connected to the fixing rod 27. The fixing rod 27 fixedly connected to the top end of the top plate 25 can connect and limit the connecting block 262 fixedly connected to the outer wall of the limiting ring 26. By sliding the connecting block 262 on the fixing rod 27, when it is necessary to connect the communication holes 241, the connecting block 262 can slide and separate from the fixing rod 27, so that the limiting ring 26 can be separated from the top of the sliding cylinder 24, thereby adjusting the position of the communication hole 241 opened on the sliding cylinder 24.

[0020] The bottom end of the connecting plate 11 is fixedly connected with a second motor 3. The driving end of the second motor 3 is fixedly connected with a threaded rod 31. The threaded rod 31 is threadedly connected to the adjusting plate 32. The second motor 3 fixedly connected to the bottom end of the connecting plate 11 is used to install the threaded rod 31, so that after the driving end of the second motor 3 is connected to the threaded rod 31, it can drive the threaded rod 31 to rotate. When the threaded rod 31 rotates, it can adjust the height of the adjusting plate 32 in the adjusting box 13, thereby adjusting the position of the sliding plate 33.

[0021] A limiting rod 311 is fixedly connected between the connecting plate 11 and the inner wall of the adjusting box 13. The limiting rod 311 penetrates through the adjusting plate 32. A circular hole 321 for making way for the first motor 2 is opened at the center of the adjusting plate 32. The limiting rod 311 fixedly connected between the connecting plate 11 and the inner wall of the adjusting box 13 is used to enable the adjusting plate 32 to slide horizontally when the adjusting plate 32 adjusts its up and down position. The circular hole 321 is used to avoid the upward movement of the adjusting plate 32 being limited by the first motor 2 when the adjusting plate 32 slides upward, ensuring that the sliding plate 33 closes both sides of the carbon storage box 22.

[0022] Working principle and usage process of the utility model: The rotating cylinder 21 and the carbon storage tank 22 in the pressure tank body 1 can drive the carbon to be in the air to adsorb the carbon. The pressure tank body 1 is a sealed tank body. Under the pressurized state, the carbon can absorb more oxygen to ensure the separation effect of oxygen in the air, thereby improving the separation concentration of nitrogen. When it is necessary to take out the nitrogen from which oxygen has been separated, the adjusting plate 32 can be moved upward so that the sliding plate 33 fits on both sides of each carbon storage tank 22 to seal the carbon storage tank 22, making the carbon that has absorbed oxygen be between the sliding plates 33 and not contact the separated nitrogen. At this time, the sliding cylinder 24 slidably connected to the inner wall of the rotating cylinder 21 can be rotated to connect the communication holes 241, so that the carbon originally under the pressurized state contacts the outside through the communication holes 241 and the sliding cylinder 24, and the desorbed oxygen can be discharged through the sliding cylinder 24. At the same time, after the nitrogen in the pressure tank body 1 is connected to the pipeline for extracting nitrogen, it can prevent the desorbed oxygen of the carbon from mixing with the nitrogen again after the pressure changes, thereby ensuring the extraction concentration of nitrogen.
