Description

Technical Field

[0001] The invention relates to the technical field of adsorbent pressing devices, and in particular to an adsorbent pressing device in a pressure swing adsorption tower and a use method thereof. Background Art

[0002] Pressure swing adsorption (PSA) is an important gas separation technology, which is widely used in many fields such as hydrogen purification, carbon dioxide capture, air separation, etc. Its basic principle is to use the difference in adsorption performance of adsorbents to different gas components under pressure changes to achieve gas separation. As the core of the pressure swing adsorption process, the performance of the adsorbent directly affects the separation effect;

[0003] Since the adsorbent inside the adsorption tower needs to be compressed to make it compact when in use, the existing devices generally install a spring plate on the top of the adsorption material, and achieve the compacted state through the elastic force on the spring plate. Since the spring compaction method is static and single, it is difficult to respond quickly to the adsorbent sedimentation or other working condition changes in real time, and it is also easy to compress the material evenly when the adsorption material settles. It is easy to cause the adsorbent bed to become loose or not compacted tightly to produce channeling, which affects the adsorption efficiency of the adsorption material. Summary of the invention

[0015] The ground is arranged between two rotating balls.

[0016] Furthermore, a method for using a pressing device for an adsorbent in a pressure swing adsorption tower, the method comprising the following steps:

[0017] S1: First, place the lower half of the device inside the main body, then place the adsorbed material on the circular disc, then completely place the device inside the main body, and connect the connecting disc to the main body with bolts, and then connect the air intake pipe to the external air pump delivery pipe;

[0018] S2: Then, the top of the connection plate is connected to the external exhaust pipe, and then the air pump of the air pump delivery pipeline is started to deliver the gas to be adsorbed to the inside of the main body. When the gas enters the main body, the adsorption material inside it will adsorb the passing gas;

[0019] S3: At the same time, when the device is placed in the main body, the pressure plate will fit on the top of the adsorbent material and squeeze the adsorbent material.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when the pump body delivery pipe delivers gas to the inside of the main body, the flow of gas will enter the telescopic cylinder through the circular hole on the telescopic cylinder, and the gas will flow upward rapidly along the guidance of the spiral structure inside the telescopic cylinder. At the same time, another part of the gas will enter the semicircular frame at the bottom of the pressure plate. When the two parts of the gas enter the semicircular frame, the gas will impact the surface of the fan shaft. After the fan shaft is impacted by the gas, it will drive the conical gear cylinder to rotate. When the conical gear cylinder rotates, the gas will be blown into the cylindrical groove and enter the compression chamber. At the same time, when the conical gear cylinder rotates, the rotation of the conical gear cylinder will also drive a plurality of connecting toothed discs to rotate synchronously. When the connecting toothed discs rotate, they will drive the two compression blocks through the transmission toothed disc to make them rotate relative to each other inside the compression chamber. When the two compression blocks rotate relative to each other inside the compression chamber, the rotation of the compression blocks will enter the gas inside the compression chamber for compression. When the gas is compressed by the relative rotation of the two compression chambers, the compressed gas will quickly impact the hose under the continued rotation of the compression chamber. The gas enters the air jet tube and impacts the air jet pipe through the hose. Since the material of the hose is relatively soft, when the gas impacts the inside of the air jet tube through the hose, the hose will shake greatly. When the gas in multiple hoses impacts the inside of the air jet tube, the gas will be sprayed to the bottom of the screening plate through the hose. At this time, the reverse impact force generated when the gas is sprayed out through the air jet tube will drive the pressure plate to move downward. At the same time, when the gas enters the inside of the air jet tube, the gas will also impact the surface of the grid shaft and cause it to rotate. When the grid shaft rotates, it will drive the sawtooth ring to rotate on the surface of the material. When the thrust generated by the gas when it is sprayed pushes the pressure plate to move downward, it can compensate for the decrease in the compression force caused by the sedimentation of the adsorbent, so that the adsorbent can continue to be in a compressed state. At the same time, during the pressure swing adsorption process, the adsorbent frequently expands and contracts due to the adsorption and desorption cycle. Compared with the traditional compression device that only relies on a single method such as a spring, this device can effectively maintain the compact state of the adsorbent bed, reduce the occurrence of channeling, and thus improve the adsorption efficiency.

[0022] 2. In the present invention, when the gas hits the jet pipe through the hose, the hose will shake greatly. When multiple hoses are shaking, the shaking of the hoses will drive the connecting ring to move up and down. When the connecting ring moves, it will drive the connecting plate to shake. Since the elastic plate is elastic, when the connecting ring drives the connecting plate to move up and down, the elastic plate will shake rapidly during the movement of the connecting plate. When multiple elastic plates are shaking, the shaking of the elastic plate will drive the limit ring to move up and down. When the limit ring moves downward, the movement of the limit ring will drive the annular plate to move downward. When the annular plate moves downward, it will push the curved tubes through multiple universal rods to expand the multiple curved tubes outward. When the multiple curved tubes expand outward, the side walls of the curved tubes will contact the side walls of the rotating ball. Then, when the limit ring drives the annular plate to move downward, the annular plate will push the curved tubes through the curved tubes. The base plate moves downward, and when it moves downward, it will pull the fan rod downward. When the fan rod moves downward, it will contact the bottom of the serrated tube through the plug rod on the surface and rotate along the serrated groove on the serrated tube. When the plug rod drives the fan rod to rotate, the rotation of the fan rod will drive the curved tube to rotate synchronously through the base plate. When the curved tube rotates, it will drive the rotating ball to rotate on the surface of the adsorption material through the friction force on the surface of the rotating ball. In the process of the pressure plate pressing the adsorbent, the rotation of the rotating ball can change the friction mode between the pressure plate and the adsorbent from static friction to rolling friction, so that when the pressure plate applies the pressing force, the local pressure on the adsorbent particles can be greatly reduced, which can effectively avoid the breakage of particles due to excessive local pressure, protect the integrity of the adsorbent particles, thereby reducing the damage to the adsorption performance of the adsorbent and ensuring the progress of the adsorption process.

[0023] 3. In the present invention, when the elastic plate drives the limit ring to move up and down, the movement of the limit ring will drive the annular plate to move synchronously. When the annular plate moves up and down, the movement of the annular plate will drive the chassis and the fan rod to move synchronously through the curved tube. When the fan rod moves up and down, the movement of the fan rod will reciprocate between the sawtooth grooves of the upper and lower sawtooth cylinders through the insertion rod on its surface. At this time, guided by the sawtooth grooves on the sawtooth cylinder, the insertion rod will drive the fan rod to rotate. When the fan rod rotates, it will drive the chassis and the annular plate to rotate synchronously through the curved tube. When the fan rod rotates, the rotation of the fan rod will disturb the gas flowing upward and also absorb the gas sprayed onto the screening plate through the jet pipe. When the fan rod absorbs the gas, the gas will enter the conical spiral barrel and be ejected downward along the influence of the spiral groove inside the conical spiral barrel. When the jet pipe sprays the gas onto the screening plate, the gas will collide with the bottom of the screening plate and diffuse on the surface of the screening plate. At this time, when the gas around the fan rod is disturbed and the gas ejected from the jet pipe is extracted, the diffusion of the gas after collision can be reduced, and the influence of the high-speed gas ejected from the jet pipe on the upward-flowing gas inside the main body can be effectively reduced. Through this disturbance, the two gases can be better mixed, which can reduce the local airflow turbulence and the obstruction to the overall gas flow caused by high-speed jetting, and is conducive to maintaining the stability of the gas flow in the adsorption tower.

[0024] 4. In the present invention, when the rotation of the fan rod and the conical spiral cylinder disturbs the gas, the rotation of the conical spiral cylinder will swing the gas around through the inclined plate at the bottom thereof, so that the gas diffuses and flows outward. When the gas flows, the swing of the inclined plate can swing the gas into the jet hose. At the same time, when the curved tube expands outward, the expansion of the curved tube will drive the jet hose to expand outward through the spring block and make it on the surface of the rotating ball. Afterwards, when the rotation of the inclined plate swings the gas outward, the flow of the gas will drive the jet hose to shake, and at the same time, part of the gas will enter the jet hose and spray outward. At this time, when the jet hose sprays gas, it will also cause the jet hose to shake. When the jet hose shakes, The surface of the rotating ball continuously strikes the rotating ball and causes it to vibrate. This vibration disperses the pressure on the adsorbent particles, so that the pressure that may have been concentrated on certain particle contact points can be dynamically transmitted to more particles through the vibration and movement of the rotating ball, so that the force between the adsorbent particles changes from simple static extrusion to dynamic force, reducing the risk of breakage caused by long-term static extrusion between particles. At the same time, the vibration can also rearrange the adsorbent particles, which helps to break the local tight stacking or agglomeration of the adsorbent, and make the adsorbent particles more evenly distributed in the bed, thereby improving the diffusion efficiency of the gas in the adsorbent bed.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] S3: At the same time, when the device is placed in the main body 1, the pressing plate 204 will fit on the top of the adsorbent material and squeeze the adsorbent material.

When the two parts of the gas enter the semicircular frame, the gas will impact the surface of the fan shaft 304. After being impacted by the gas, the fan shaft 304 will drive the conical gear cylinder 305 to rotate. When the conical gear cylinder 305 rotates, the gas will be blown into the cylindrical groove 303 and enter the In the compression chamber 302, at the same time, when the conical gear cylinder 305 rotates, the rotation of the conical gear cylinder 305 will also drive the multiple connecting toothed discs 403 to rotate synchronously. When the connecting toothed disc 403 rotates, it will drive the two compression blocks 401 through the transmission toothed disc 402 to make them rotate relatively inside the compression chamber 302. When the two compression blocks 401 rotate relatively inside the compression chamber 302, the rotation of the compression blocks 401 will enter the gas inside the compression chamber 302 for compression. When the gas is compressed by the relative rotation of the two compression chambers 302, the compressed gas will be further compressed in the compression chamber 302. The gas will continue to rotate and quickly impact into the hose 404, and then impact into the jet pipe through the hose 404. Since the material of the hose 404 is relatively soft, when the gas impacts the inside of the jet pipe through the hose 404, the hose 404 will shake greatly. When the gas in multiple hoses 404 impacts the inside of the jet pipe, the gas will be sprayed to the bottom of the screening plate 202 through the hose 404. At this time, the reverse impact force generated when the gas is sprayed out through the jet pipe will drive the pressure plate 204 to move downward. At the same time, when the gas enters the inside of the jet pipe, the gas will also impact the surface of the grid shaft 405. The surface is moved and rotated, and the grid shaft 405 drives the serrated ring 406 to rotate on the surface of the material. When the thrust generated by the gas ejected pushes the pressure plate 204 to move downward, it can compensate for the decrease in the pressing force caused by the adsorbent sedimentation, so that the adsorbent can continue to be kept in a compressed state. At the same time, during the pressure swing adsorption process, the adsorbent frequently expands and contracts due to the adsorption and desorption cycle. Compared with the traditional compression device that only relies on a single method such as a spring, this device can effectively maintain the tight state of the adsorbent bed and reduce the occurrence of channeling, thereby improving the adsorption efficiency.

[0056] When the gas hits the jet pipe through the hose 404, the hose 404 will shake greatly. When multiple hoses 404 are shaking, the shaking of the hoses 404 will drive the connecting ring 501 to move up and down. When the connecting ring 501 moves, it will drive the connecting plate 502 to shake. Since the elastic plate 503 is elastic, when the connecting ring 501 drives the connecting plate 502 to move up and down, the elastic plate 503 will shake quickly when the connecting plate 502 moves. When multiple elastic plates 503 are When the elastic plate 503 is shaken, the shaking of the limit ring 504 will drive the limit ring 504 to move up and down. When the limit ring 504 moves downward, the movement of the limit ring 504 will drive the annular plate 505 to move downward. When the annular plate 505 moves downward, it will push the curved tubes 602 through the multiple universal rods 601 to make the multiple curved tubes 602 expand outward. When the multiple curved tubes 602 expand outward, the side walls of the curved tubes 602 will contact the side walls of the rotating ball 802. Then, when the limit ring 504 drives the annular plate 505 to move downward, the annular plate 505 The plate 505 will push the base 603 downward through the curved tube 602. When the base 603 moves downward, it will pull the fan rod 604 downward. When the fan rod 604 moves downward, it will contact the bottom of the sawtooth cylinder 702 through the insertion rod on the surface and rotate along the sawtooth groove on the sawtooth cylinder 702. When the insertion rod drives the fan rod 604 to rotate, the rotation of the fan rod 604 will drive the curved tube 602 to rotate synchronously through the base 603. When the curved tube 602 rotates, it will drive the rotating ball 802 to rotate through the friction force on the surface of the rotating ball 802. 802 rotates on the surface of the adsorbent material. During the process of the pressure plate 204 pressing the adsorbent, the rotation of the rotating ball 802 can transform the friction mode between the pressure plate 204 and the adsorbent from static friction to rolling friction, so that when the pressure plate 204 applies the pressing force, the local pressure on the adsorbent particles can be greatly reduced, which can effectively avoid the particle breakage caused by excessive local pressure, protect the integrity of the adsorbent particles, thereby reducing the damage to the adsorption performance of the adsorbent and ensuring the progress of the adsorption process.

[0057] When the elastic plate 503 drives the limit ring 504 to move up and down, the movement of the limit ring 504 will drive the annular plate 505 to move synchronously. When the annular plate 505 moves up and down, the movement of the annular plate 505 will drive the base 603 and the fan rod 604 to move synchronously through the curved tube 602. When the fan rod 604 moves up and down, the movement of the fan rod 604 will reciprocate between the sawtooth grooves of the upper and lower sawtooth cylinders 702 through the insertion rod on its surface. At this time, guided by the sawtooth grooves on the sawtooth cylinder 702, the insertion rod will drive the fan rod 604 to rotate. When the fan rod 604 rotates, it will drive the base 603 and the annular plate 505 to rotate synchronously through the curved tube 602. When the fan rod 604 rotates, the rotation of the fan rod 604 will disturb the upward flowing gas and also spray it to the The gas on the screening plate 202 is absorbed, and when the fan rod 604 absorbs the gas, the gas will enter the conical spiral cylinder 703 and be ejected downward along the influence of the spiral groove inside the conical spiral cylinder 703. When the jet pipe sprays the gas onto the screening plate 202, the gas will collide with the bottom of the screening plate 202 and diffuse on the surface of the screening plate 202. At this time, when the gas around the fan rod 604 is disturbed and the gas ejected from the jet pipe is extracted, the diffusion of the gas after collision can be reduced, and the influence of the high-speed gas ejected from the jet pipe on the upward flowing gas inside the main body 1 can be effectively reduced. Through this disturbance, the two gases can be better mixed, which can reduce the local airflow turbulence and the obstruction to the overall gas flow caused by high-speed jetting, which is beneficial to maintaining the stability of the gas flow in the adsorption tower.

[0058] When the rotation of the fan rod 604 and the conical spiral cylinder 703 disturbs the gas, the rotation of the conical spiral cylinder 703 will swing the gas around through the inclined plate at its bottom, causing the gas to diffuse and flow outward. When the gas flows, the swing of the inclined plate can swing the gas into the jet hose 705. At the same time, when the curved tube 602 expands outward, the expansion of the curved tube 602 will drive the jet hose 705 to expand outward through the spring block and place it on the surface of the rotating ball 802. Thereafter, when the rotation of the inclined plate swings the gas outward, the flow of the gas will drive the jet hose 705 to shake, and at the same time, part of the gas will enter the jet hose 705 and be ejected outward. At this time, when the jet hose 705 ejects gas, it will also cause the jet hose 705 to shake, and the jet When the hose 705 is shaken, it will continuously knock the rotating ball 802 on its surface and cause it to vibrate. This vibration will disperse the pressure on the adsorbent particles, so that the pressure that may have been concentrated on certain particle contact points can be dynamically transmitted to more particles through the vibration and the movement of the rotating ball 802, so that the force between the adsorbent particles is changed from simple static extrusion to dynamic force, reducing the risk of breakage between particles caused by long-term static extrusion. At the same time, the vibration can also rearrange the adsorbent particles, which helps to break the local tight accumulation or agglomeration of the adsorbent, and make the adsorbent particles more evenly distributed in the bed, thereby improving the diffusion efficiency of the gas in the adsorbent bed.
