Description

Technical Field

[0001] The present invention relates to the technical field of gas processing, and in particular to a gas adsorption separation device. Background Art

[0002] Gas adsorption is widely used in the treatment of gaseous pollutants and organic waste gas in the industrial field, especially in chemical industry, environmental protection and air pollution control, where gas adsorption technology shows significant treatment effect. This method separates harmful substances from gas through porous adsorption materials. However, the existing technology still has some obvious defects in practical application.

[0003] First, the uneven gas flow rate and distribution are the main problems faced by existing gas adsorption devices. When the gas enters the adsorption device at a high flow rate, the airflow is concentrated and cannot be evenly diffused to the entire surface of the adsorption material, resulting in a shortened contact time between the gas and the adsorption material, and most of the airflow only contacts with a local area of ​​the adsorption plate, causing the adsorption material to fail locally and quickly, affecting the overall treatment efficiency.

[0004] Secondly, the gas treatment continuity is insufficient. Existing adsorption devices often use a single chamber structure, which cannot achieve continuous adsorption and exhaust operations. During operation, the adsorption chamber needs to be shut down and regenerated after adsorption saturation, and continuous treatment cannot be achieved, which greatly reduces the working efficiency of the equipment and cannot meet the needs of large-scale gas treatment.

[0005] In addition, the existing adsorption materials have low regeneration efficiency after long-term use. During the regeneration process, the adsorption plate often cannot be evenly exposed to the regeneration gas, resulting in insufficient regeneration of some adsorption areas, shortening the service life of the activated carbon adsorption plate, and increasing equipment maintenance and operating costs.

[0006] Therefore, in view of the problems existing in the prior art such as uneven gas distribution, low treatment efficiency and unsatisfactory regeneration effect, there is an urgent need for a gas adsorption separation device that can improve the uniformity of gas adsorption, realize continuous operation and have efficient regeneration function to meet the needs of industrial applications. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0008] Therefore, the object of the present invention is to provide a gas adsorption separation device, comprising a first cylinder, a second cylinder connected to both ends of the first cylinder by welding, and adsorption components located at both ends of the first cylinder.

[0009] A movable plate is arranged in the first cylinder between the two adsorption components, and a first air collecting cavity and a second air collecting cavity are formed between the two adsorption components and the movable plate.

[0010] The first air intake branch pipe and the second air intake branch pipe are welded and connected to the wall of the first cylinder respectively, the first air intake branch pipe is connected to the first air collecting chamber, the second air intake branch pipe is connected to the second air collecting chamber, one end of the first air intake branch pipe and the second air intake branch pipe are connected to the air intake main pipe through a tee, and the air intake main pipe is used to introduce gas.

[0011] The adsorption assembly includes a fixed ring and an activated carbon adsorption plate fixed in the inner ring of the fixed ring. The outer wall of the fixed ring is respectively welded with a first rotating shaft and a second rotating shaft. The first rotating shaft and the second rotating shaft both pass through the first cylinder and are connected to the first cylinder bearing.

[0012] First grooves are provided on both sides of the movable plate, a lampshade is arranged at the notch of the first groove, a base plate is fixed with bolts at the bottom of the first groove, and a plurality of heating lamps are fixed on the base plate by soldering.

[0013] A sealing ring is welded and fixed on the inner wall of the second cylinder, and a sealing plate is sealingly fitted in the inner circle of the sealing ring.

[0014] A polytetrafluoroethylene lining is provided on the inner wall of the first cylinder. Since the movable plate will reciprocate in the first cylinder, the lubricating properties of the polytetrafluoroethylene lining can reduce friction, thereby facilitating smooth movement of the movable plate. At the same time, the sealing properties of the polytetrafluoroethylene lining can improve the sealing effect between the fixed ring and the movable plate and the first cylinder, thereby ensuring that all gases can pass through the activated carbon adsorption plate, thereby improving the adsorption and separation treatment effect of the gas.

[0015] As the preferred technical solution:

[0016] In the gas adsorption separation device as described above, the inner diameter of the first cylinder is smaller than the inner diameters of the second cylinder and the sealing ring, and the first cylinder, the second cylinder and the sealing ring are coaxial.

[0017] Through the above technical solution, the end of the second cylinder that is not connected to the first cylinder is open, so that the gas in the first cylinder can be discharged through the open end of the second cylinder after passing through the activated carbon adsorption plate;

[0018] The inner diameters of the first cylinder, the second cylinder and the sealing ring are designed so that when the sealing plate is opened and the fixing ring is driven to rotate by the first rotating shaft and the second rotating shaft, the fixing ring can be partially screwed into the sealing ring, thereby ensuring that the rotation of the fixing ring is not hindered.

[0019] In the gas adsorption separation device as described above, a plurality of convex strips are formed on the outer circular wall of the movable plate, and a groove matching the convex strips is formed on the inner wall of the first cylinder between the two adsorption components, and the convex strips are embedded in the grooves.

[0020] Through the above technical solution, the convex strips and the grooves play a guiding role, so that the movable plate can move back and forth horizontally along the axis of the first cylinder. Both the convex strips and the grooves also play a limiting role to prevent the movable plate from rotating when moving, thereby ensuring that the first conductive contact and the second conductive contact can be accurately aligned.

[0021] In the gas adsorption separation device as described above, the end surfaces on both sides of the movable plate are respectively provided with a first air guide groove and a second air guide groove, and the cross-sections of the first air guide groove and the second air guide groove are both "U"-shaped.

[0022] Through the above technical solution, when the movable plate moves to fit with the fixed ring on one side of the first gas collecting chamber, the first gas guide groove will be aligned with the first air intake branch pipe, so that the gas in the first air intake branch pipe will be sent into the first gas guide groove, and the gas will gradually diffuse into the first gas collecting chamber;

[0023] Similarly, when the movable plate moves to fit with the fixed ring on one side of the second gas collecting chamber, the second air guide groove will be aligned with the second air intake branch pipe, so that the gas in the second air intake branch pipe will be sent into the second air guide groove, and the gas will gradually diffuse into the second gas collecting chamber.

[0024] In a gas adsorption separation device as described above, a hole groove is opened in the movable plate, the end of the hole groove is connected to the first groove, the head end of the hole groove is connected to the end face of the movable plate, a first conductive contact is fixed in the head end of the hole groove, a first wire is inserted into the hole groove, and the first conductive contact and the substrate are electrically connected through the wire.

[0025] The fixing ring is provided with a second annular groove facing the movable plate, a cover plate is arranged in the second groove, a through hole for the first conductive contact to penetrate is arranged on the cover plate, and a second conductive contact for matching with the first conductive contact is arranged in the second groove.

[0026] The second conductive contact is soldered with a second wire, the second rotating shaft is a hollow structure, the second rotating shaft is connected to the second groove, and the second wire passes through the second rotating shaft and is connected to the power grid through a conductive slip ring.

[0027] Through the above technical solution, when the movable plate moves to fit with the fixed ring, the first conductive contact will pass through the through hole and abut against the second conductive contact. Since the second wire is connected to the power supply, the first conductive contact is also connected to the power grid through the second conductive contact. In this way, the heating lamp is powered on and operates, and the structure is reasonable.

[0028] Since current will pass through the first conductive contact and the second conductive contact, in order to avoid electric shock, the movable plate and the fixed ring are selected to be made of insulating material, preferably insulating ceramic, so as to ensure overall safety. The movable plate and the first conductive contact as well as the fixed ring and the second conductive contact are fixed by bolts or glue, which can improve the installation firmness of the first conductive contact and the second conductive contact, and ensure that after the movable plate and the fixed ring are fitted, the first conductive contact and the second conductive contact can be accurately docked and contacted, thereby achieving stable operation of the heating lamp.

[0029] In the gas adsorption separation device as described above, a sealing step is provided in the inner ring of the sealing ring, the sealing plate is embedded in the sealing step, a rubber sealing ring is bonded to the sealing step, and the sealing plate and the rubber sealing ring are tightly pressed against each other.

[0030] Through the above technical solution, the setting of the sealing step can increase the contact area between the sealing ring and the sealing plate, and in combination with the rubber sealing ring, the sealing performance between the sealing ring and the sealing plate can be improved.

[0031] In a gas adsorption and separation device as described above, a group of first rotating seats are welded and fixed on a side wall of the sealing ring away from the fixed ring, a rotating rod connected to its bearings passes through the first rotating seats, the rotating rod passes through one end of the connecting plate and is welded and fixed to the connecting plate, and the other end of the connecting plate is welded and fixed to the sealing plate.

[0032] The top end of the connecting plate extends out from the second cylinder, and two second rotating seats are welded and fixed on the outer wall of the second cylinder, and a transmission rod connected to the bearings of the two second rotating seats passes through.

[0033] The second transmission gear is fixed to the upper bayonet of the transmission rod, and the first transmission gear meshing with the second transmission gear is fixed to the upper bayonet of the rotating rod.

[0034] Through the above technical solution, the transmission rod can drive the rotating rod to rotate axially on the first rotating seat through the meshing action of the first transmission gear and the second transmission gear, and then the rotating rod drives the sealing plate to rotate through the connecting plate, so that the sealing plate can be separated from the sealing ring, and the sealing ring is in an open state. When the transmission rod drives the rotating rod to rotate in the opposite direction, the sealing plate can seal the sealing ring again.

[0035] Compared with the prior art, the present invention has at least the following beneficial effects:

[0036] (1) Optimize gas flow rate and distribution to improve adsorption effect: The present invention divides the gas adsorption chamber into two gas collection chambers by setting a movable plate, and uses an air intake branch pipe to input gas into different gas collection chambers. By controlling the air intake volume and the movement of the movable plate, the gas can be evenly distributed in the adsorption chamber and maintain an appropriate flow rate. This design effectively prolongs the contact time between the gas and the activated carbon adsorption plate, avoids local failure of the adsorption material caused by excessive airflow concentration, and improves the overall adsorption and separation effect.

[0037] (2) Continuous operation capability and improved separation efficiency: This device adopts a dual-chamber alternating air intake and exhaust working mode. The movable plate is pushed by the gas to continuously move back and forth between the two gas collecting chambers, thereby realizing continuous gas adsorption and separation operations. The gas is evenly filtered when passing through the activated carbon adsorption plate, achieving uninterrupted gas treatment, greatly improving the working efficiency of the device, and is suitable for large-scale gas separation scenarios.

[0038] (3) Regeneration function of activated carbon adsorption plate, extending service life: By setting the fixed ring and rotating shaft structure, the activated carbon adsorption plate can be rotated 180 degrees, allowing the regeneration gas to pass through the adsorption plate in the opposite direction for regeneration. The uniform flow of regeneration gas combined with the auxiliary heating of the heating lamp can effectively decompose the adsorbed harmful substances and restore the adsorption capacity of the activated carbon, greatly extending the service life of the activated carbon adsorption plate and reducing the replacement frequency and cost.

[0039] (4) Intelligent heating control to improve regeneration efficiency: This device is designed with a heating lamp system based on conductive contacts. When the movable plate moves to the adsorption plate position, the conductive contact automatically connects to the power supply and starts the heating lamp to efficiently heat the activated carbon plate. This design makes the regeneration process intelligent and does not require manual intervention, ensuring the automation and efficiency of the heating and regeneration process.

DETAILED DESCRIPTION

[0049] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0051] See also Figure 1 , Figure 2 and Figure 6 The present invention provides a technical solution: a gas adsorption separation device, comprising a first cylinder 1, and a second cylinder 2 welded to the first cylinder 1 at both ends, and adsorption components located at both ends of the first cylinder 1, a sealing ring 8 is welded and fixed on the inner wall of the second cylinder 2, and a sealing plate 9 is sealed in the inner circle of the sealing ring 8.

[0052] A movable plate 3 is provided in the first cylinder 1 between the two adsorption components, and a first air collecting chamber 10 and a second air collecting chamber 11 are formed between the two adsorption components and the movable plate 3. A first air intake branch pipe 4 and a second air intake branch pipe 5 are welded and connected to the wall of the first cylinder 1, respectively. The first air intake branch pipe 4 is connected to the first air collecting chamber 10, and the second air intake branch pipe 5 is connected to the second air collecting chamber 11. One end of the first air intake branch pipe 4 and the second air intake branch pipe 5 are connected to an air intake main pipe through a tee, and the air intake main pipe is used to introduce gas.

[0053] During operation, the gas to be treated can be introduced into the air intake main pipe, and the gas in the air intake main pipe will be diverted to the first air intake branch pipe 4 and the second air intake branch pipe 5 through a tee. Valves are provided on the first air intake branch pipe 4 and the second air intake branch pipe 5. At this time, the valve on the second air intake branch pipe 5 is closed first, so that the gas can only pass through the first air intake branch pipe 4 to enter the first air collecting chamber 10 until the first air collecting chamber 10 is filled with gas, which will push the movable plate 3 to move to the second air collecting chamber 11. At this time, the valve on the first air intake branch pipe 4 is closed, the valve on the second air intake branch pipe 5 is opened, and the sealing plate 9 on one side of the first air collecting chamber 10 is opened.

[0054] Then the gas continuously passes through the second air inlet branch pipe 5 into the second air collecting chamber 11, and the gas volume inside the second air collecting chamber 11 continues to increase, which will push the movable plate 3 to move toward the first air collecting chamber 10, so that the movable plate 3 will squeeze the gas in the first air collecting chamber 10 and force the gas to pass through the adsorption component on one side of the first air collecting chamber 10. The adsorption component can adsorb and separate harmful substances in the gas. In this process, only the air intake volume needs to be controlled to adjust the movement speed of the movable plate 3, which means that the gas extrusion rate can be controlled, and the gas is distributed throughout the first air collecting chamber 10, and the gas is evenly distributed. Through the above method, it can be ensured that the gas is fully in contact with the adsorption component and the contact is uniform, thereby improving the adsorption and separation effect.

[0055] When the gas in the first gas collecting chamber 10 is squeezed out, it means that the second gas collecting chamber 11 is filled with gas. At this time, the valve on the first air intake branch pipe 4 is opened, the valve on the second air intake branch pipe 5 is closed, and the sealing plate 9 on one side of the first gas collecting chamber 10 is closed. The sealing plate 9 on one side of the second gas collecting chamber 11 is opened, and the gas is passed into the first gas collecting chamber 10 through the first air intake branch pipe 4 again. After the gas volume inside the first gas collecting chamber 10 continues to increase, it will push the movable plate 3 to move toward the second gas collecting chamber 11, and then the gas in the second gas collecting chamber 11 can be squeezed out. In this way, the gas will pass through the adsorption component on one side of the second gas collecting chamber 11, and the adsorption component can adsorb and separate harmful substances in the gas.

[0056] By repeating the above steps, continuous adsorption and separation operations can be achieved.

[0057] like Figure 2 , Figure 3 and Figure 4As shown, the adsorption assembly includes a fixed ring 6, and an activated carbon adsorption plate 7 fixed in the inner ring of the fixed ring 6, and the first rotating shaft 23 and the second rotating shaft 24 are welded and fixed to the outer wall of the fixed ring 6 respectively, the first rotating shaft 23 and the second rotating shaft 24 both pass through the first cylinder 1 and are connected to the bearing of the first cylinder 1, the inner diameter of the first cylinder 1 is smaller than the inner diameter of the second cylinder 2 and the sealing ring 8, and the first cylinder 1, the second cylinder 2 and the sealing ring 8 are coaxial.

[0058] A motor is bolted to the first cylinder 1, and sprockets are pinned on the main shaft of the motor and the first rotating shaft 23, and the sprocket sleeves on the main shaft of the motor and the first rotating shaft 23 are meshed with chains, thereby forming a chain drive between the main shaft of the motor and the first rotating shaft 23, that is, after the motor is powered on, the two first rotating shafts 23 can be driven to rotate synchronously through the main shaft, and when the first rotating shaft 23 rotates, the activated carbon adsorption plate 7 can be driven to rotate through the fixed ring 6.

[0059] When the activated carbon adsorption plate 7 needs to be regenerated, the motor will drive the first rotating shaft 23 to rotate. The first rotating shaft 23 cooperates with the second rotating shaft 24 to make the activated carbon adsorption plate 7 on the fixed ring 6 rotate 180°. At this time, the regeneration gas can be introduced into the intake manifold, and the regeneration gas will be diverted to the first intake branch pipe 4 and the second intake branch pipe 5 through the tee. By switching the valves on the first intake branch pipe 4 and the second intake branch pipe 5, the regeneration gas can be alternately controlled to enter the first gas collecting chamber 10 and the second gas collecting chamber 11. In this way, the regeneration gas in the first gas collecting chamber 10 and the second gas collecting chamber 11 can be squeezed out by moving the movable plate 3, and the regeneration gas can pass through the activated carbon adsorption plate 7 in the reverse direction, thereby realizing the regeneration operation of the activated carbon adsorption plate 7.

[0060] During this process, the moving speed of the movable plate 3 can still be adjusted to control the rate of regeneration gas extrusion, and the regeneration gas is evenly distributed in the first gas collecting chamber 10 and the second gas collecting chamber 11, so that it can fully and evenly contact the activated carbon adsorption plate 7, thereby improving the regeneration effect.

[0061] like Figure 3 and Figure 5 As shown, a plurality of convex strips 12 are protruded from the outer circular wall of the movable plate 3, a groove 13 adapted to the convex strips 12 is provided on the inner wall of the first cylinder 1 between the two adsorption components, the convex strips 12 are embedded in the grooves 13, and the end faces on both sides of the movable plate 3 are respectively provided with a first air guide groove 32 and a second air guide groove 33, and the cross-sections of the first air guide groove 32 and the second air guide groove 33 are both "U"-shaped.

[0062] The convex strips 12 and the grooves 13 cooperate with each other so that the movable plate 3 will not be stuck in the first cylinder 1 when moving, thereby ensuring that the movable plate 3 moves smoothly.

[0063] The arrangement of the first air guide groove 32 and the second air guide groove 33 enables gas to still be introduced into the first air collecting cavity 10 and the second air collecting cavity 11 after the movable plate 3 fits with the fixed rings 6 on both sides, and the structure is reasonable.

[0064] As Figure 4 and Figure 5 shown, first grooves 14 are formed on both sides of the movable plate 3. A lamp cover 15 is arranged at the notch of the first groove 14. A substrate 16 is bolted and fixed at the bottom of the first groove 14. A plurality of heating lamps 17 are soldered and fixed on the substrate 16. A hole groove is formed in the movable plate 3. The end of the hole groove is communicated with the first groove 14, and the start of the hole groove is communicated with the end face of the movable plate 3. A first conductive contact 18 is fixed in the start of the hole groove. A first wire is inserted into the hole groove. The first conductive contact 18 and the substrate 16 are electrically connected through the wire. A circular second groove 19 is formed on one side of the fixed ring 6 facing the movable plate 3. A cover plate 20 is arranged in the second groove 19. A through hole 21 for the first conductive contact 18 to penetrate is formed in the cover plate 20. A second conductive contact 22 for cooperating with the first conductive contact 18 is arranged in the second groove 19. A second wire is soldered to the second conductive contact 22. The second rotating shaft 24 is of a hollow structure and is communicated with the second groove 19. The second wire passes through the second rotating shaft 24 and is connected to the power grid through a conductive slip ring.

[0065] During the regeneration process, the movable plate 3 will move in the first cylinder 1 and will alternately fit with the fixed rings 6 on both sides. When the movable plate 3 fits with the fixed ring 6, the first conductive contact 18 will pass through the through hole 21 and contact the second conductive contact 22. Since the second conductive contact 22 is connected to the power grid through the second wire, the first conductive contact 18, the first wire and the heating lamp 17 are also connected to the circuit. The heating lamp 17 operates with electricity. The heating lamp 17 can be an infrared heating lamp or an electric heating lamp, which is selected according to the actual situation. The heating lamp 17 can heat the activated carbon adsorption plate 7. The substances adsorbed on the activated carbon adsorption plate 7 can be thermally decomposed at high temperature and desorbed from the activated carbon adsorption plate 7 with the flow of the regeneration gas. In this way, the adsorption points on the surface of the activated carbon adsorption plate 7 are reactivated, and the activated carbon adsorption plate 7 resumes its adsorption performance and can continue to work.

[0066] A circuit switch is arranged on the second wire. When performing the adsorption operation, the second wire is disconnected through the circuit switch. In this way, when the first conductive contact 18 contacts the second conductive contact 22, it will not be electrified, and the heating lamp 17 will not operate.

[0067] The arrangement of the conductive slip ring enables the second wire not to be wound with the external circuit when the second rotating shaft 24 rotates axially, avoiding the twisting and breaking of the second wire and the external circuit.

[0068] As Figure 1 、 Figure 6 and Figure 7 As shown, a sealing step 34 is provided in the inner ring of the sealing ring 8, and the sealing plate 9 is embedded in the sealing step 34. A rubber sealing ring is bonded to the sealing step 34, and the sealing plate 9 is tightly pressed against the rubber sealing ring. A group of first rotating seats 26 are welded and fixed on the side wall of the sealing ring 8 away from the fixing ring 6, and a rotating rod 25 connected to its bearings passes through the first rotating seats 26. The rotating rod 25 passes through one end of the connecting plate 27 and is welded and fixed to the connecting plate 27. The other end of the connecting plate 27 is welded and fixed to the sealing plate 9. The top end of the connecting plate 27 extends out from the second cylinder 2, and two second rotating seats 29 are welded and fixed on the outer wall of the second cylinder 2. A transmission rod 28 connected to its bearings passes through the two second rotating seats 29, and a second transmission gear 31 is fixed to the transmission rod 28 with a pin, and a first transmission gear 30 meshing with the second transmission gear 31 is fixed to the top end of the rotating rod 25 with a pin.

[0069] When the first air guide groove 32 or the second air guide groove 33 is filled with exhaust gas or regeneration gas, the sealing plate 9 is located in the sealing step 34, so that the sealing ring 8 can be sealed. In this way, when the first air guide groove 32 or the second air guide groove 33 is filled with gas, the gas will not overflow.

[0070] When the movable plate 3 squeezes out the first air guiding groove 32 or the second air guiding groove 33 , the sealing plate 9 on one side of the first air guiding groove 32 or the second air guiding groove 33 can be opened, so that the gas can be discharged through the sealing ring 8 .

[0071] A locking bolt is screwed into the second rotating seat 29 , so that the transmission rod 28 can be fixed by tightening the locking bolt against the transmission rod 28 , thereby preventing the transmission rod 28 from rotating.

[0072] In the description of this specification, "connection", "installation", "fixation" and the like should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
