Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a VOC waste gas treatment device based on zeolite rotor adsorption. Background Technology

[0002] Zeolite rotors are core adsorption materials widely used in industrial waste gas treatment, playing a crucial role in volatile organic compound (VOC) control technologies. As a key component of waste gas purification systems, zeolite rotors, through their porous structure and excellent adsorption performance, can efficiently concentrate low-concentration, high-volume VOC gases, providing a high-concentration waste gas stream for subsequent thermal combustion or catalytic oxidation treatments, thereby significantly improving overall treatment efficiency and energy utilization. Particularly in industries such as coating, printing, chemical, and electronics manufacturing, where VOC emissions are characterized by complex composition, large concentration fluctuations, and large volumes, the application of zeolite rotors has a decisive impact on achieving environmental compliance and reducing environmental pollution risks.

[0003] Utility model patent CN210278705U discloses a zeolite rotor waste gas treatment device, including a housing. Inside the housing, a filter device, a zeolite rotor assembly, and a combustion furnace are sequentially installed along the airflow direction. The zeolite rotor assembly consists of a first zeolite rotor, a second zeolite rotor, and a third zeolite rotor, with the rotational speeds of the first and third zeolite rotors being lower than that of the second zeolite rotor. This device, by setting multiple zeolite rotors with different rotational speeds, achieves effective staged adsorption treatment of waste gas containing complex organic compounds, improving the overall adsorption efficiency of the system. Compared to the traditional single-rotor structure, it increases treatment capacity and reduces operating costs while requiring a smaller footprint, demonstrating good economic efficiency and applicability.

[0004] However, in practical applications, existing zeolite rotor exhaust gas treatment equipment still exhibits a series of significant technical limitations. Specifically, while existing technologies employ multi-stage zeolite rotor combinations to enhance adsorption capacity, their structural design lacks consideration for the ease of maintenance of the zeolite rotor itself. Because zeolite rotors operate in high-temperature, high-humidity, or dusty airflow environments for extended periods, they are prone to clogging, deactivation, or localized damage. Furthermore, most current equipment uses a fixed installation method, making disassembly, cleaning, or replacement of the rotor components extremely inconvenient. This often requires prolonged downtime and reliance on specialized technicians, severely impacting the continuous operating efficiency and ease of maintenance. In addition, this structural design increases the labor and time costs of later maintenance, failing to meet the demands of modern environmental protection equipment for intelligent, modular, and highly maintainable systems. Therefore, to address the numerous shortcomings of existing technologies, we urgently need an innovative VOC exhaust gas treatment device based on zeolite rotor adsorption to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a VOC waste gas treatment device based on zeolite rotor adsorption, which solves the problem that the existing technology lacks consideration for the convenience of maintaining the zeolite rotor body. Because the zeolite rotor operates in a high temperature, high humidity or dusty airflow environment for a long time, it is prone to problems such as blockage, deactivation or local damage. Moreover, most current equipment adopts a fixed installation method, which makes it extremely inconvenient to disassemble, clean or replace the rotor assembly.

[0006] To achieve the above objectives, this utility model provides a VOC waste gas treatment device based on zeolite rotor adsorption, including a support frame, and a support cylinder provided inside the support frame, and a zeolite rotor provided inside the support cylinder.

[0007] A bearing rod is fixedly connected to one side of the zeolite rotor, and a drive motor is fixedly connected to one side of the bearing frame by bolts. A fixing plate is detachably connected to one side of the bearing cylinder, and one end of each bearing rod passes through the fixing plate and the side wall of the bearing frame in sequence through a bearing sleeve. The extended end of the bearing rod is connected to the output shaft of the drive motor. A bearing plate is provided on one side of the bearing cylinder, and a sealing ring is fixedly connected to one side of the bearing plate. A sealing groove for use with the sealing ring is opened on one side of the bearing cylinder. A rotary joint is connected to one side of the bearing plate, and a fan is fixedly connected to one side of the bearing frame by bolts. The inlet of the fan is connected to one end of the rotary joint.

[0008] The support frame has cylinders fixedly connected to both sides by bolts, and the output shafts of the two cylinders are fixedly connected to one side of the support plate through the side wall of the support frame.

[0009] The bottom of the bearing cylinder is provided with an arc-shaped bearing plate, and mounting plates are fixedly connected to both sides of the bottom of the arc-shaped bearing plate. Both mounting plates are fixedly connected to the inner bottom of the bearing frame by bolts.

[0010] The outlet of the fan is connected to a connecting hose, and one end of the connecting hose passes through the side wall of the support frame through a side groove, and one end of the connecting hose is connected to one side of the rotary joint.

[0011] The fixed plate has an air inlet slot.

[0012] The outer side of the bearing cylinder is fitted with a connecting ring, and one side of the connecting ring is provided with several threaded rods. One end of all the threaded rods passes through the fixing plate and the connecting ring in sequence through the threaded groove.

[0013] This utility model discloses a VOC waste gas treatment device based on zeolite rotor adsorption. Through a detachable support cylinder and fixed plate structure, combined with a sealing ring and sealing groove design, it achieves quick assembly and disassembly between the zeolite rotor and the outer shell, greatly improving the convenience of maintenance. Simultaneously, the support cylinder can be slidably disassembled from the outside of the zeolite rotor, avoiding the need for complete disassembly of the equipment to access the rotor in traditional fixed structures, effectively reducing maintenance time and labor costs. Furthermore, a stable transmission connection is used between the drive motor and the support rod, with a bearing sleeve penetrating the structure between the fixed plate and the support frame, ensuring the stability and reliability of the zeolite rotor during operation and extending the equipment's service life. The support plate and rotary joint ensure the continuity of the gas flow path, allowing waste gas to stably enter the treatment system and improving treatment efficiency. The fan, as a key power component, ensures the continuous and efficient passage of waste gas through the zeolite rotor, enhancing the overall system's treatment capacity and adaptability.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 A VOC waste gas treatment device based on zeolite rotor adsorption includes a support frame 1 and a support cylinder 2 inside the support frame 1, with a zeolite rotor 3 inside the support cylinder 2. A support rod 4 is fixedly connected to one side of the zeolite rotor 3, and a drive motor 5 is fixedly connected to one side of the support frame 1 by bolts. A fixing plate 6 is detachably connected to one side of the support cylinder 2. One end of each support rod 4 passes through the fixing plate 6 and the side wall of the support frame 1 in sequence through a bearing sleeve, and the extended end of the support rod 4 is connected to the output shaft of the drive motor 5. A support plate 11 is provided on one side of the support cylinder 2, and a sealing ring 12 is fixedly connected to one side of the support plate 11. A sealing groove 10 for use with the sealing ring 12 is opened on one side of the support cylinder 2. A rotary joint 13 is connected to one side of the support plate 11, and a fan 14 is fixedly connected to one side of the support frame 1 by bolts. The inlet of the fan 14 is connected to one end of the rotary joint 13.

[0023] First, the organic waste gas to be treated is introduced into the bearing cylinder 2 from one side of the fixed plate 6. The fan 14 is started, and its suction action guides the waste gas into the bearing cylinder 2. As the waste gas flows through the zeolite rotor 3, the volatile organic compounds in it are efficiently adsorbed by the zeolite material, achieving preliminary purification. At the same time, the drive motor 5 is started, and its output shaft drives the bearing rod 4 to rotate through transmission. The bearing rod 4 further drives the zeolite rotor 3 to rotate slowly, so that the entire rotor surface participates in the adsorption process evenly, improving the treatment efficiency and service life. When the zeolite rotor 3 needs maintenance, cleaning, or replacement, the bearing plate 11 is first separated from the bearing cylinder 2, so that the sealing ring 12 is disengaged from the sealing groove 10. Then, the connection structure between the fixed plate 6 and the bearing cylinder 2 is disassembled. Then, the bearing cylinder 2 can be slid out along the outer circumference of the zeolite rotor 3, exposing the overall structure of the zeolite rotor 3, which facilitates inspection, cleaning, or replacement without dismantling the entire equipment body, thus significantly shortening maintenance time and reducing operation difficulty.

[0024] Furthermore, cylinders 16 are fixedly connected to both sides of the bearing frame 1 by bolts, and the output shafts of the two cylinders 16 are fixedly connected to one side of the bearing plate 11 through the side wall of the bearing frame 1. When maintenance of the zeolite rotor 3 is required, the bearing plate 11 can be pushed or pulled by starting the cylinder 16 to separate it from the bearing cylinder 2, thereby simplifying the operation process of separating the sealing ring 12 from the sealing groove 10 and achieving the effect of improving maintenance convenience and work efficiency.

[0025] Furthermore, the bottom of the bearing cylinder 2 is provided with an arc-shaped bearing plate 17, and mounting plates 18 are fixedly connected to both sides of the bottom of the arc-shaped bearing plate 17. Both mounting plates 18 are fixedly connected to the inner bottom of the bearing frame 1 by bolts. This design provides a stable support for the bearing cylinder 2, ensuring that it remains stable during operation and preventing positional displacement or structural damage caused by vibration, thereby enhancing equipment stability and extending service life.

[0026] Furthermore, a connecting hose 15 is connected to the outlet of the fan 14, and one end of the connecting hose 15 passes through the side wall of the support frame 1 via the side groove 19. The connecting hose 15 is also connected to one side of the rotary joint 13. After treatment, the exhaust gas is discharged through the connecting hose 15. This flexible connection method allows the support plate 11 to maintain the integrity of the gas flow path when it moves, avoiding the risk of leakage or breakage that may be caused by rigid pipes, thus improving the reliability and adaptability of the system.

[0027] Furthermore, an air inlet slot 20 is provided on the fixed plate 6, through which the organic waste gas enters the interior of the bearing cylinder 2. This design optimizes the path of the waste gas into the bearing cylinder 2, ensuring that the waste gas can be evenly distributed and fully contact the zeolite rotor 3, thereby improving the adsorption efficiency and achieving the purpose of improving the waste gas treatment effect.

[0028] Furthermore, a connecting ring 7 is sleeved on the outer side of the bearing cylinder 2, and several threaded rods 8 are provided on one side of the connecting ring 7. One end of all the threaded rods 8 passes through the fixing plate 6 and the connecting ring 7 in sequence through the threaded groove 9. In the working process, this structure strengthens the connection between the bearing cylinder 2 and the fixing plate 6, making them more secure during operation and reducing the problem of loosening or falling off due to long-term use. This achieves the effect of enhancing the overall structural stability and ensuring the safe operation of the equipment.

[0029] In summary:

[0030] First, the organic waste gas to be treated enters the bearing cylinder 2 from one side of the fixed plate 6 through the air inlet slot 20. The fan 14 is started, and its suction action guides the waste gas into the bearing cylinder 2. As the waste gas flows through the zeolite rotor 3, the volatile organic compounds in it are efficiently adsorbed by the zeolite material, achieving preliminary purification. At the same time, the drive motor 5 is started, driving the bearing rod 4 to rotate. The bearing rod 4 further drives the zeolite rotor 3 to rotate slowly, so that the entire rotor surface participates in the adsorption process evenly, improving the treatment efficiency and service life. When maintenance, cleaning, or replacement of the zeolite rotor 3 is required, the air intakes fixed to both sides of the bearing frame 1 by bolts are started first. The cylinder 16, with its output shaft, pushes or pulls the bearing plate 11 to separate it from the bearing cylinder 2, causing the sealing ring 12 to disengage from the sealing groove 10. Then, the connection structure between the fixing plate 6 and the bearing cylinder 2 is disassembled. A connecting ring 7 is sleeved on the outer side of the bearing cylinder 2. Several threaded rods 8 are provided on one side of the connecting ring 7. All threaded rods 8 pass through the fixing plate 6 and the connecting ring 7 via threaded grooves 9. After disassembly, the bearing cylinder 2 can be slid out along the outer circumference of the zeolite rotor 3, exposing the overall structure of the zeolite rotor 3. This facilitates inspection, cleaning, or replacement without dismantling the entire equipment body, significantly shortening maintenance time and reducing operational difficulty. To further improve the stability and structural reliability of the device, an arc-shaped bearing plate 17 is provided at the bottom of the bearing cylinder 2. Mounting plates 18 are fixedly connected to both sides of the bottom of the arc-shaped bearing plate 17. Both mounting plates 18 are fixedly connected to the inner bottom of the bearing frame 1 by bolts. This design provides stable support for the bearing cylinder 2, preventing positional displacement or structural damage due to vibration, and enhancing the stability and long-term reliability of the equipment. In addition, a connecting hose 15 is connected to the outlet of the fan 14. One end of the connecting hose 15 passes through the side wall of the support frame 1 via the side groove 19 and is connected to one side of the rotary joint 13. The exhaust gas is discharged through the connecting hose 15 after treatment. The flexible connection method allows the support plate 11 to maintain the integrity of the gas flow path during movement, avoiding the risk of leakage or breakage that may be caused by rigid pipes, and improving the adaptability and safety of the system. By setting up a detachable support cylinder 2 and a fixed plate 6, combined with the sealing design of the sealing ring 12 and the sealing groove 10, the zeolite rotor 3 and the outer shell are quickly disassembled and assembled, greatly improving the convenience of maintenance operations and solving the problem of "inconvenience in maintaining the zeolite rotor" in the prior art. At the same time, the setting of the cylinder 16 simplifies the separation process of the support plate 11 and improves maintenance efficiency. The structure of the arc-shaped support plate 17 and the mounting plate 18 enhances the stability of the support cylinder 2 and extends the service life of the equipment. The flexible connection between the connecting hose 15 and the side groove 19 ensures the continuity of the gas flow path and improves the reliability of system operation. The air inlet groove 20 optimizes the exhaust gas entry path and improves the adsorption efficiency. The combination of the connecting ring 7, the threaded rod 8 and the threaded groove 9 strengthens the connection strength between the support cylinder 2 and the fixed plate 6 and reduces the risk of loosening and falling off.
