Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a zeolite rotor with adsorption and desorption functions. Background Technology

[0002] Zeolite rotors are highly efficient concentration and purification devices for large-volume, low-concentration VOCs waste gas. Their core function is to concentrate waste gas into high-concentration, low-volume gas through adsorption-desorption cycles, thereby reducing the investment and operating costs of downstream treatment equipment.

[0003] The zeolite rotor is a rotating wheel filled with adsorbent, divided into three zones: an adsorption zone, a regeneration zone, and a cooling zone. VOCs waste gas is introduced into the adsorption zone by a blower, where the organic pollutants are adsorbed, and the gas is purified before being discharged. Subsequently, the adsorbent rotates to the regeneration zone, where, during contact with high-temperature air, VOCs are desorbed and flow out with the regeneration air, simultaneously regenerating the adsorbent. The regenerated adsorbent is first cooled in the cooling zone before rotating back to the adsorption zone for re-adsorption. With the rotation of the rotor, the adsorbent periodically undergoes adsorption, desorption, and cooling, achieving the purification of organic waste gas.

[0004] However, in practical applications, existing zeolite rotors require the installation of high-temperature and solvent-resistant sealing materials between the partition plates and the adsorption rotor, along with the circumferences on both sides of the adsorption rotor and between the partition plates and the shell, to prevent air leakage. While this sealing design avoids gas interference between the regeneration and cooling zones, the sealing material is prone to wear under the long-term rotation of the rotor, weakening and eventually losing its sealing effect. Furthermore, replacing the sealing material is complex and affects the equipment's uptime. Utility Model Content

[0005] The purpose of this invention is to provide a zeolite rotor with adsorption and desorption functions to solve the problem of easy wear of the sealing materials on both sides of the current zeolite rotor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a zeolite rotor with adsorption and desorption functions, comprising a housing, a rotor assembly rotatably installed within the housing, and a drive assembly for driving the rotor assembly to rotate. The conversion connection assembly includes support plates located on the front and rear sides of the center of the housing cavity, and three sleeve cylinders fixedly fitted onto the support plates and evenly arranged circumferentially. Connecting cylinders are fixedly fitted onto the front and rear walls of the housing and slidably fitted onto each of the sleeve cylinders. Telescopic cylinders are installed on the front and rear walls of the housing and used to push and pull the support plates to move back and forth. The rotor assembly includes a disc-shaped housing rotatably installed within the housing and zeolite units located in three sections within the inner cavity of the disc-shaped housing. Sleeves are fixedly fitted onto the front and rear walls of the disc-shaped housing at positions corresponding to its three sections, and the sleeves slidably fit onto the corresponding sleeve cylinders.

[0007] Preferably, the front and rear walls of the disc-shaped housing are respectively fixedly connected to the diffuser shrouds at the positions corresponding to its three partitions, and the sleeve end is fixedly sleeved on the middle of the corresponding diffuser shroud.

[0008] Preferably, the outer peripheral wall of the disc-shaped housing is provided with an annular groove in the middle, and an external gear ring is provided in the annular groove. The drive assembly includes a housing fixed to the middle of the top surface of the chassis, a servo motor fixed to the front wall of the housing and with its power output shaft extending into the inner cavity of the housing, and a drive gear provided in the inner cavity of the housing and fixedly mounted on the power output shaft of the servo motor. A slot is provided in the middle of the top surface of the chassis corresponding to the bottom of the drive gear, and the drive gear meshes with the external gear ring through the slot.

[0009] Preferably, a plurality of guide rods are vertically fixed on the end face of the support plate away from the wheel assembly and near the outer edge, and a guide sleeve that slides and engages with the guide rods is fixed on the wall of the inner cavity of the chassis opposite to the guide rods.

[0010] Preferably, the plurality of guide rods are evenly distributed circumferentially on the support plate.

[0011] Preferably, the outer peripheral walls of the front and rear ends of the sleeve body are fitted with sealing rings through annular grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model relates to a zeolite rotor with adsorption and desorption functions. Before the rotor assembly rotates, a telescopic cylinder pulls the support plate, causing the sleeve to detach from the sleeve, thus facilitating the rotation of the rotor assembly. After the zeolite unit completes the functional area switching, the telescopic cylinder pushes the support plate again, causing the sleeve to re-engage with the corresponding sleeve, allowing each area to complete its corresponding functional operation. This effectively avoids the problem of easy wear of the sealing materials on both sides of the zeolite rotor. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: a zeolite rotor with adsorption and desorption functions, wherein three connecting cylinders 3 are fixedly fitted on the outer periphery of the middle of the front and rear walls of the casing 1, and the three connecting cylinders 3 are evenly arranged circumferentially. The two connecting cylinders 3 facing each other at the front and rear form a group, wherein the front connecting cylinder 3 of the first group is the exhaust gas inlet, and the rear connecting cylinder 3 is used for the exhaust gas after adsorption treatment, that is, the first group of connecting cylinders 3 corresponds to the adsorption zone; the front and rear connecting cylinders 3 of the second group are used for the introduction of high-temperature desorption air and the exhaust of desorbed VOCs, that is, the second group of connecting cylinders 3 corresponds to the regeneration zone; the front and rear connecting cylinders 3 of the third group are used for the introduction of cooling air and the exhaust of cooled air, that is, the third group of connecting cylinders 3 corresponds to the cooling zone.

[0026] The rotor assembly 2 includes a disc-shaped housing 2.1 rotatably mounted within the chassis 1 and zeolite units 2.2 located in three sections within the inner cavity of the disc-shaped housing 2.1. These three sections are three circumferentially divided areas within the inner cavity of the disc-shaped housing 2.1. Diffuser hoods 2.3 are fixedly connected to the front and rear walls of the disc-shaped housing 2.1 corresponding to the positions of its three sections, and the ends of sleeves 2.4 are fixedly fitted into the middle of the corresponding diffuser hoods 2.3. Furthermore, an annular groove 2.1.1 is provided in the middle of the outer peripheral wall of the disc-shaped housing 2.1, and an external gear ring 2.1.2 is provided within the annular groove 2.1.1. The front and rear ends of the outer peripheral wall of the disc-shaped housing 2.1 are connected to the inner wall of the chassis 1 via rotary supports to ensure that the disc-shaped housing 2.1 can rotate smoothly relative to the chassis 1.

[0027] The drive assembly 5 includes a housing 5.1 fixed to the center of the top surface of the chassis 1, a servo motor 5.3 fixed to the front wall of the housing 5.1 with its power output shaft extending into the inner cavity of the housing 5.1, and a drive gear 5.2 located within the inner cavity of the housing 5.1 and fixedly mounted on the power output shaft of the servo motor 5.3. A slot is provided in the center of the top surface of the chassis 1 corresponding to the bottom of the drive gear 5.2, and the drive gear 5.2 meshes with the external gear ring 2.1.2 through the slot. That is, the drive assembly 5 is used to drive the entire rotary wheel assembly 2 to rotate. The rotary wheel assembly 2 rotates 120° each time.

[0028] The conversion connection assembly 4 includes a support plate 4.1 located on the front and rear sides of the middle of the inner cavity of the chassis 1, and three sleeve cylinders 4.2 fixedly fitted in the middle of the support plate 4.1 and evenly arranged in the circumferential direction; the end of the sleeve cylinder 4.2 near the front and rear walls of the chassis 1 is slidably fitted into the inner cavity of the connecting cylinder 3, and the other end of the sleeve cylinder 4.2 is slidably fitted into the sleeve 2.4.

[0029] The piston cylinder body of the telescopic cylinder 6 is installed in the middle of the front and rear walls of the housing 1, and the piston rod of the telescopic cylinder 6 passes through the middle of the front and rear walls of the housing 1 and is fixedly connected to the center of the support plate 4.1. That is, the telescopic cylinder 6 is used to push and pull the support plate 4.1 to move back and forth.

[0030] In summary, during use, VOCs exhaust gas is introduced into the front connecting cylinder 3 of the first set of connecting cylinders 3 by a blower. Subsequently, the exhaust gas flows from the connecting cylinder 3 through the corresponding sleeve body 4.2 and sleeve 2.4 into a section of the rotor assembly 2. That is, after the exhaust gas is diffused by the diffuser hood 2.3, it flows through the corresponding zeolite unit 2.2, and after passing through the zeolite unit 2.2, it is discharged from the rear diffuser hood 2.3 in sequence through the corresponding sleeve 2.4, sleeve body 4.2 and connecting cylinder 3. During this process, the organic pollutants in the exhaust gas are adsorbed, and the gas is purified before being discharged.

[0031] Then, the telescopic cylinder 6 on the front wall of the chassis 1 pulls the front support plate 4.1 forward, while the telescopic cylinder 6 on the rear wall of the chassis 1 pulls the rear support plate 4.1 backward, so that the sleeve body 4.2 disengages from the sleeve 2.4 respectively.

[0032] The drive assembly 5 then drives the rotary wheel assembly 2 to rotate 120°, causing the zeolite unit 2.2, which has undergone waste gas adsorption, to rotate back to a position directly opposite the regeneration zone.

[0033] The telescopic cylinders 6 on the front and rear sides extend simultaneously, allowing the sleeve body 4.2 to re-sleeve with the corresponding sleeve 2.4. At this time, high-temperature gas is introduced into the connecting cylinder 3 of the second group, so that the VOCs of the corresponding zeolite unit 2.2 are desorbed during contact with the high-temperature air and discharged from the corresponding connecting cylinder 3 with the regeneration air, while the adsorbent is regenerated.

[0034] Then, the telescopic cylinder 6 on the front wall of the casing 1 pulls the front support plate 4.1 forward, while the telescopic cylinder 6 on the rear wall of the casing 1 pulls the rear support plate 4.1 backward, causing the sleeve cylinder 4.2 to disengage from the sleeve 2.4. The drive assembly 5 then drives the rotating wheel assembly 2 to rotate 120°, causing the desorbed zeolite unit 2.2 to rotate back to a position directly opposite the cooling zone. The telescopic cylinders 6 on both the front and rear sides extend simultaneously, allowing the sleeve cylinder 4.2 to re-engage with the corresponding sleeve 2.4, so that the regenerated zeolite unit 2.2 can undergo cooling treatment in the cooling zone.

[0035] Subsequently, drive assembly 5 drives the rotor assembly to rotate 120° again, causing the zeolite unit 2.2 after the cooling zone to rotate back to the adsorption zone to adsorb the waste gas. As the rotor assembly 2 rotates, the zeolite unit 2.2 periodically performs adsorption, desorption, and cooling to achieve efficient purification of organic waste gas.

[0036] It is worth noting that during the back-and-forth movement of the support plate 4.1, the corresponding end of the sleeve 4.2 is always sleeved inside the connecting cylinder 3; only the sleeve 4.2 and the corresponding sleeve 2.4 switch between being sleeved and disengaged. Before each rotation of the drive wheel assembly 2, the drive assembly 5 ensures that the sleeve 4.2 and the corresponding sleeve 2.4 are disengaged. After the drive assembly 5 drives the drive wheel assembly 2 to rotate 120°, the sleeve 4.2 and the corresponding sleeve 2.4 are re-sleeved by the pushing action of the telescopic cylinder 6.

[0037] To facilitate smooth and stable forward and backward movement of the conversion connection assembly 4 during the extension and retraction of the telescopic cylinder 6, multiple guide rods 4.3 are vertically fixed to the outer edge of the end face of the support plate 4.1 away from the rotary wheel assembly 2. A guide sleeve 4.4, which slides and engages with the guide rods 4.3, is fixed to the wall of the housing 1 opposite to the guide rods 4.3. The multiple guide rods 4.3 are evenly distributed circumferentially on the support plate 4.1. That is, when the support plate 4.1 moves forward and backward, the guide rods 4.3 and the guide sleeve 4.4 move relative to each other, providing a guiding function.

[0038] To ensure the airtightness of the front and rear ends of the sleeve body 4.2 after it is fitted with the connecting cylinder 3 and the sleeve 2.4, sealing rings are fitted on the outer peripheral walls of the front and rear ends of the sleeve body 4.2 through annular grooves.
