Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of waste gas treatment equipment technology, specifically an environmental protection device for adsorbing waste gas using zeolite molecular sieves. Background Technology
[0002] Currently, commonly used waste gas treatment methods include adsorption, absorption, and catalytic combustion. Among these, adsorption is widely used due to its advantages such as simple operation, low cost, and good purification effect. Zeolite molecular sieves, as a highly efficient adsorption material, have attracted considerable attention in the field of waste gas treatment due to their unique pore structure and large specific surface area, exhibiting excellent adsorption performance for various harmful substances in waste gas.
[0003] In existing waste gas adsorption devices, multiple zeolite sub-sieves are typically fixed directly inside the pipe or purifier. This can lead to longer contact time between the zeolite sub-sieves that are in direct contact with the waste gas, causing the front-end zeolite sub-sieves to fail quickly, while the rear zeolite sub-sieves are not fully utilized. This results in a low overall utilization rate of the zeolite molecular sieves, increasing the frequency and cost of material replacement. At the same time, the uneven distribution of the adsorption capacity of the zeolite sub-sieves can also affect the overall waste gas treatment effect of the device, making it difficult to consistently achieve the expected purification standards. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an environmental protection device for adsorbing waste gas using zeolite molecular sieves, achieved through the following technical solution: An environmental protection device for adsorbing waste gas using zeolite molecular sieves includes a housing, an air inlet pipe fixedly installed on one side of the housing, an exhaust pipe fixedly installed at the center of the top surface of the housing, a support plate rotatably installed inside the housing, a support frame fixedly installed on the top surface of the support plate, several honeycomb zeolite molecular sieves arranged inside the support frame, and a drive assembly for driving the support plate to rotate inside the housing.
[0005] Furthermore, the support frame includes a column, which is fixedly installed at the center of the top surface of the support plate, and a through hole is opened at the center of the top surface of the column. A baffle is fixedly installed on the top surface of the column, and the baffle is rotatably connected to the inner wall of the shell. A central hole communicating with the through hole is opened on the top surface of the baffle. Several evenly distributed through slots are opened on the outer periphery of the column, and each through slot is connected to the through hole. A honeycomb zeolite sieve is provided in each through slot.
[0006] Furthermore, a stop block is fixedly installed on the bottom surface of the through groove near the through hole, and an adjustable limiting component is provided on the outer side of the through groove.
[0007] Furthermore, the limiting component includes; Support rods are fixedly installed on both sides of the through groove on the outer periphery of the column; A limiting plate is provided, wherein the outer end of one of the support rods is rotatably mounted with the limiting plate, and a slot is provided on the front side of the limiting plate near the movable end. When the limiting plate is rotated to a preset position, the slot engages with the other support rod.
[0008] Furthermore, the drive assembly includes a drive motor and a reducer. The drive motor and the reducer are both fixed to the bottom surface of the inner wall of the housing. The output shaft of the drive motor is fixedly connected to the input shaft of the reducer. A connecting shaft is fixedly installed at the center of the bottom surface of the support plate.

[0010] Furthermore, the baffle is rotatably connected to the inner wall of the housing via a bearing, and an axial seal is provided between the baffle and the housing.
[0011] Compared with the existing technology, the beneficial effects of this utility model are: 1.

At the same time, the setting of multiple honeycomb zeolite sub-screens also increases the waste gas treatment capacity of the equipment. 2. The limiting components on both sides of the through slot in the support frame, through the cooperation of the support rod, the limiting plate and the slot, can quickly fix or loosen the honeycomb zeolite sub-screen. In addition, the design of the inspection port and the sealing door on the shell greatly facilitates the installation, replacement and maintenance of the honeycomb zeolite sub-screen, and reduces the operation and maintenance cost of the equipment.

[0014] Example: An environmental protection device for adsorbing waste gas using zeolite molecular sieves. like Figure 1 As shown in Figure 4, an environmental protection device for adsorbing waste gas using zeolite molecular sieves has the following specific structure: The housing 10 has an air inlet pipe 101 fixedly installed on one side and an exhaust pipe 102 fixedly installed at the center of the top surface of the housing 10. A support plate 20 is rotatably installed inside the housing 10, and a support frame 30 is fixedly installed on the top surface of the support plate 20. Several honeycomb zeolite sub-sieves 40 are provided inside the support frame 30. A drive assembly 50 for driving the support plate 20 to rotate is provided inside the housing 10. The air inlet pipe 101 is arranged perpendicular to the front of the housing 10. This arrangement allows the exhaust gas to flow along the inner wall of the housing 10 and form a rotating airflow when it enters the housing 10. The rotating airflow can contact the honeycomb zeolite sub-sieves 40 inside the housing more evenly, avoiding the exhaust gas from concentrating and impacting a part of the honeycomb zeolite sub-sieves, thereby improving the overall utilization rate of the honeycomb zeolite sub-sieves and the exhaust gas treatment efficiency.
[0015] The working principle described above is as follows: Exhaust gas enters the interior of housing 10 through intake pipe 101, and exhaust pipe 102 is connected to an external suction fan. During operation, drive component 50 drives support plate 20 to rotate, which in turn causes support frame 30 on support plate 20 and honeycomb zeolite sieve 40 inside to rotate together. During the rotation, exhaust gas comes into full contact with honeycomb zeolite sieve 40. Honeycomb zeolite sieve 40 uses its adsorption properties to adsorb harmful substances in exhaust gas. The clean gas after adsorption treatment is discharged through exhaust pipe 102 at the center of the top surface of housing 10. The drive component 50 drives the honeycomb zeolite sub-sieve 40 to rotate, increasing the contact opportunities and contact area between the waste gas and the honeycomb zeolite sub-sieve 40, thereby improving the efficiency of waste gas adsorption treatment. The arrangement of multiple honeycomb zeolite sub-sieves 40 can simultaneously adsorb and treat waste gas, increasing the processing capacity of the equipment and adapting to the waste gas treatment needs of different discharge volumes.
[0016] The support frame 30 includes a column 301, which is fixedly installed at the center of the top surface of the support plate 20. A through hole 302 is opened at the center of the top surface of the column 301. A baffle 303 is fixedly installed on the top surface of the column 301. The baffle 303 is rotatably connected to the inner wall of the shell 10. A central hole 304 communicating with the through hole 302 is opened on the top surface of the baffle 303. A plurality of evenly distributed through slots 305 are opened on the outer periphery of the column 301. All through slots 305 are connected to the through hole 302, and each through slot 305 is provided with a honeycomb zeolite sieve 40.
[0017] After the exhaust gas enters the shell 10, it comes into contact with the honeycomb zeolite sieve 40 in the rotating support frame 30. The honeycomb zeolite sieve 40 adsorbs the exhaust gas. Since the through groove 305 is connected to the through hole 302 of the column 301, some of the gas that has undergone preliminary adsorption can enter the through hole 302 through the through groove 305, and then flow upward through the central hole 304 on the baffle 303, and finally be discharged from the exhaust pipe 102. The baffle 303 rotates with the column 301 and is rotatably connected to the inner wall of the shell 10, which can reduce the leakage of gas from the gap between the baffle 303 and the shell 10. The through groove 305 on the column 301 provides a stable installation position for the honeycomb zeolite sub-sieve 40, and the structure of the through groove 305 communicating with the through hole 302 makes the gas flow path more reasonable and improves the gas flow efficiency; the baffle 303 reduces the possibility of waste gas that has not been fully adsorbed being discharged directly from the top, ensuring the effect of waste gas treatment.
[0018] Each of the through slots 305 has a stop block 306 fixedly installed on the bottom surface near the through hole 302, and each of the through slots 305 has an adjustable limiting component 60. The stop block 306 limits the honeycomb zeolite sieve 40 to prevent it from moving towards the through hole 302, while the adjustable limiting component 60 on the outside of the through slot 305 fixes the honeycomb zeolite sieve 40 from the other side, ensuring that the honeycomb zeolite sieve 40 will not shift or fall off due to rotation during equipment operation.
[0019] The limiting component 60 includes: Support rod 601, the support rod 601 is fixedly installed on both sides of the through groove 305 on the outer periphery of the column 301; A limiting plate 602 is rotatably mounted on the outer end of one of the support rods 601. A slot 603 is provided on the front side of the limiting plate 602 near the movable end. When the limiting plate 602 is rotated to a preset position, the slot 603 engages with the other support rod 601.
[0020] When it is necessary to install or replace the honeycomb zeolite sub-sieve 40, rotate the limiting plate 602 so that its movable end disengages from the other support rod 601, and the honeycomb zeolite sub-sieve 40 can be placed into or removed from the through groove 305. After installation, rotate the limiting plate 602 so that the slot 603 in front of the limiting plate 602 engages with the other support rod 601, thereby limiting and fixing the honeycomb zeolite sub-sieve 40 in the through groove 305, ensuring the stability of the honeycomb zeolite sub-sieve 40 during equipment operation.
[0021] The drive assembly 50 includes a drive motor 501 and a reducer 502. Both the drive motor 501 and the reducer 502 are fixed to the bottom surface of the inner wall of the housing 10. The output shaft of the drive motor 501 is fixedly connected to the input shaft of the reducer 502. A connecting shaft 201 is fixedly installed at the center of the bottom surface of the support plate 20. The lower end of the connecting shaft 201 is coaxial with and fixedly connected to the output shaft of the reducer 502. After the drive motor 501 starts, its output shaft drives the input shaft of the reducer 502 to rotate. After the reducer 502 adjusts the speed, it drives the connecting shaft 201 to rotate through its output shaft. The connecting shaft 201 then drives the support plate 20 to rotate, ultimately realizing the rotation of the support frame 30 and the honeycomb zeolite sieve 40. By using a drive motor 501 and a reducer 502 in combination, the rotation speed of the support plate 20 can be precisely controlled to meet the needs of different waste gas treatment conditions. The reducer 502 can increase the output torque, ensuring that the support plate 20 and the components on it can rotate stably, thus improving the reliability of the equipment operation.
[0022] A maintenance port 103 is provided on one side of the housing 10, and a sealing door 104 is hinged inside the maintenance port 103. During normal operation of the equipment, the sealing door 104 is closed to seal the maintenance port 103 and prevent exhaust gas from leaking from the maintenance port 103. When it is necessary to inspect, maintain or replace the components inside the housing 10, the sealing door 104 is opened and the inside of the housing 10 is entered through the maintenance port 103 to carry out the operation.
[0023] The baffle 303 is rotatably connected to the inner wall of the housing 10 via a bearing, and an axial seal is provided between the baffle 303 and the housing 10. This rotatable connection reduces the friction between the baffle 303 and the housing 10 during rotation, allowing the baffle 303 to rotate freely. Simultaneously, the axial seal between the baffle 303 and the housing 10 prevents axial leakage of gas through the gap between them, ensuring that the gas flows only along a predetermined path, i.e., after being adsorbed by the honeycomb zeolite sieve 40, it is discharged from the exhaust pipe 102. This improves the efficiency and effectiveness of waste gas treatment and reduces environmental pollution.
