[0019] Reference Figures 1 to 3 This embodiment provides a zeolite rotary concentrator, including a base 1, a rotary wheel 2, a rotating unit 3, a driving unit 4, and a ratchet mechanism 5.

[0020] The base 1 serves as the basic support structure for the entire device and is typically made of welded or cast steel. It is used to install and secure all other components.

[0021] The rotating wheel 2 is integrally mounted on the base 1. The rotating wheel 2 includes a fixed housing 21, which is firmly fixed to the base 1 by bolts or welding. On both sides of the housing 21, there are air inlets 22 and air outlets 23, respectively. The organic waste gas to be treated enters through the air inlet 22, and the purified gas is discharged through the air outlet 23.

[0022] The rotating unit 3 is the core functional component of the rotor 2, and it is rotatably installed inside the housing 21. The rotating unit 3 includes a rotating shaft 32, a cylindrical body 33, and multiple partitions 34. One end of the rotating shaft 32 is rotatably connected to the inner wall of the housing 21 via a bearing, while the other end extends through the side wall of the housing 21 to the outside and is connected to the drive unit 4 for transmission. The cylindrical body 33 is typically cylindrical, and its center is fixedly connected to the rotating shaft 32 via multiple radially distributed partitions 34. These partitions 34 uniformly divide the internal space of the cylindrical body 33 into multiple independent fan-shaped regions along the circumference, each region constituting a functional zone 31. Each functional zone 31 is filled with zeolite molecular sieves (not shown in the figure) as an adsorption carrier for adsorbing organic pollutants in the waste gas. The functional zones 31 are airtightly isolated from each other by the partitions 34, laying the foundation for subsequent zoned treatment.

[0023] The drive unit 4 is used to drive the rotating unit 3 to rotate intermittently. The drive unit 4 includes a drive motor 43, a half gear 41, and a driven gear 42. The drive motor 43 is fixedly mounted on the base 1 or the housing 21, and its output shaft is connected to the half gear 41. The driven gear 42 is coaxially fixed with the rotating shaft 32 of the rotating unit 3. When the drive motor 43 starts, it drives the half gear 41 to rotate. Since the half gear 41 only has teeth at 180 degrees or a specific angle, when its toothed part meshes with the driven gear 42, it will drive the driven gear 42 and the rotating shaft 32 to rotate a certain angle. If the rotating wheel is divided into 12 sections, it will rotate 30 degrees each time. When its toothless part slides past the driven gear 42, the driven gear 42 and the rotating unit 3 remain stationary. This process is repeated cyclically, thereby realizing the intermittent rotation of the rotating unit 3. The drive motor 43 is fixed to the base 1 by a mounting bracket.

[0024] To ensure that the rotating unit 3 can only rotate in a preset single direction, such as clockwise, during the driving process, and to prevent it from reversing or overshooting due to airflow impact or inertia during stationary periods, this utility model is equipped with a ratchet mechanism 5. The ratchet mechanism 5 includes a ratchet 51 and a pawl 52. The ratchet 51 is coaxially fixed to the driven gear 42 of the driving unit 4. The pawl 52 is oscillatingly mounted on the base 1 or housing 21 via a pin, and its tip is always inclined to press against the tooth groove of the ratchet 51 by an elastic element 53 (such as a torsion spring or compression spring). When the half gear 41 drives the driven gear 32 to rotate in the forward direction, the pawl 52 will slide over the back of the teeth of the ratchet 51; when the rotation stops or there is a reversing tendency, the pawl 52 will engage in the tooth groove of the ratchet 51, forming a mechanical self-lock, effectively preventing reverse movement and ensuring the stability and reliability of the equipment operation.

[0025] To achieve continuous adsorption, desorption, and cooling operations, adsorption, desorption, and cooling zones (not shown in the figure) are respectively set on the fixed housing 21 at different circumferential positions corresponding to the rotating unit 3. The air inlet 22 and outlet 23 correspond to the adsorption zone. The desorption zone is connected to a high-temperature desorption gas inlet (not shown), through which high-temperature gas is introduced to desorb the organic matter adsorbed by the zeolite. The cooling zone is connected to a cooling gas inlet (not shown), through which room-temperature air is introduced to lower the temperature of the zeolite and restore its adsorption performance. As the rotating unit 3 rotates intermittently, each functional zone 31 sequentially circulates through the adsorption zone, desorption zone, and cooling zone, completing a full working cycle of adsorption-desorption-cooling regeneration.

[0026] To prevent airflow crosstalk between the functional zones 31 and the housing 21 during adsorption, desorption, and cooling processes, which could severely affect processing efficiency, a sealing structure 6 is provided between the rotating unit 3 and the fixed housing 21. In this embodiment, the sealing structure 6 is a sealing strip disposed on both end faces and circumferential edges of the rotating unit 3. This sealing strip can be made of a high-temperature resistant and wear-resistant elastic material, such as graphite, polytetrafluoroethylene, or special rubber. Through a slight interference fit, it achieves a tight seal of the gap, ensuring the airflow independence of each process zone.

[0027] During operation, the drive motor 43 starts, driving the rotating unit 3 to rotate by one functional zone angle through the meshing of the half gear 41 and the driven gear 42. During rotation, the pawl 52 slides over the ratchet 51, and after reaching the new position, the pawl 52 engages with the tooth groove under the action of the elastic element 53, locking the position. During the static period, one functional zone 31 faces the adsorption zone, and the exhaust gas enters through the air inlet 22. The organic matter is adsorbed by the zeolite, and the purified gas is discharged from the air outlet 23. At the same time, another functional zone 31 faces the desorption zone, where it is desorbed and concentrated by high-temperature gas; and another functional zone 31 faces the cooling zone, where it is cooled and regenerated by cooling gas.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
