Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon vacuum desorption equipment, specifically to activated carbon adsorption vacuum desorption equipment based on microwave heating. Background Technology

[0002] In waste gas treatment, activated carbon inside an adsorption-desorption chamber is often used to adsorb toxic gases. The activated carbon is then used to fully adsorb the molecules of organic components in the waste gas. When a certain saturation level is reached, the activated carbon stops adsorbing. To allow the activated carbon to be reused, a desorption treatment is required.

[0003] In existing technologies, activated carbon is typically packed inside containers such as adsorption towers or adsorption boxes. To prevent the activated carbon from being too loose and affecting the adsorption effect, existing technologies generally install support plates to support the activated carbon inside the adsorption box. However, activated carbon granules have a limited lifespan. During the replacement of activated carbon, new activated carbon granules need to be added to the support plates for adsorption. However, during the replacement process, the activated carbon granules are usually placed directly on the support plates. This makes it difficult to ensure that the newly filled activated carbon is evenly distributed inside the equipment, thus affecting the uniformity and stability of the adsorption effect. Uneven distribution of activated carbon can easily lead to poor local adsorption effects, making it impossible to effectively remove some pollutants and reducing the overall processing efficiency and performance of the equipment.

[0039] Reference Figures 1-3 The inner wall of the box 1 has an annular groove, and an annular microwave heater 10 is installed in the annular groove. A protective box is fixedly installed on the side wall of the box 1, and a microwave generator 11 is installed in the protective box. A waveguide 12 is provided to connect the microwave generator 11 and the microwave heater 10. Specifically, the activated carbon particles can be heated by the microwave generator 11 in conjunction with the microwave heater 10. At the same time, the activated carbon particles can be vacuum desorbed by the vacuum pump 9, so that the adsorbed organic pollutants can be desorbed from the surface of the activated carbon particles.

[0040] Reference Figure 3 and Figure 4The positioning mechanism includes a positioning port 13, a first cavity 14, a positioning block 15, a threaded rod 16, and a rotating mechanism. Multiple positioning ports 13 are provided on the side wall of the support cover 5, and multiple first cavities 14 are provided inside the box cover 2. Each first cavity 14 passes through the mounting groove 6 and is shaped to match the positioning port 13. The positioning block 15 is slidably disposed within the first cavity 14 and is shaped to match the positioning port 13. The threaded rod 16 is rotatably disposed on the side wall of the first cavity 14 and extends into the positioning block 15 via a threaded engagement. The rotating mechanism is disposed on the box cover 2 and is used to drive multiple threaded rods 16 to rotate synchronously. The rotating mechanism includes a second cavity, a second bevel gear 18, and a driving mechanism. A second cavity is provided inside the box cover 2 on one side of the first cavity 14. A first bevel gear 17 is rotatably disposed on the side wall of the second cavity near the threaded rod 16. The first bevel gear 17 engages with the threaded rod... 16 is fixedly connected. The second bevel gear 18 is rotatably mounted on the inner top wall of the second cavity. The second bevel gear 18 meshes with the first bevel gear 17. The drive mechanism is located inside the cover 2 and is used to drive multiple second bevel gears 18 to rotate synchronously. The drive mechanism includes a third cavity, a first gear ring 20, a second gear 21, and a first motor 22. An annular third cavity is opened on one side of the multiple second cavities inside the cover 2. The first gear 19 is rotatably mounted on one side of the second bevel gear 18 inside the third cavity. A connecting rod is fixedly mounted between the first gear 19 and the second bevel gear 18. The first gear ring 20 is rotatably mounted on the first gear ring 20 and meshes with the first gear 19. The second gear 21 is rotatably mounted inside the third cavity and meshes with the first gear ring 20. The first motor 22 is mounted on the cover 2, and the output end of the first motor 22 is fixedly connected to the second gear 21.

[0041] Specifically, the operator controls the first motor 22 to work, which drives the second gear 21 to rotate. Simultaneously, the meshing of the second gear 21 with the first gear ring 20 drives the first gear ring 20 to rotate. In turn, the meshing of the first gear ring 20 with the first gear 19 drives the first gear 19 and the second bevel gear 18 to rotate. Thus, the meshing of the second bevel gear 18 with the first bevel gear 17 drives the threaded rod 16 to rotate. In turn, the threaded engagement of the threaded rod 16 with the positioning block 15 drives the positioning block 15 to move. Thus, after the support cover 5 extends into the mounting groove 6, the positioning block 15 can be engaged with the positioning port 13 to install and fix the support cover 5.

[0042] Reference Figure 2 and Figure 3 A support ring 23 is fixedly installed on the side wall of the housing 1, and a sealing ring 24 is fixedly installed on the top side wall of the support ring 23. The sealing ring 24 contacts the support cover 5 and can seal the support cover 5 and the housing 1 to prevent exhaust gas leakage.

[0043] Working principle: During use, the operator adds activated carbon granules to the support cover 5, then inserts the support cover 5 into the mounting groove 6. The operator then controls the first motor 22, which drives the second gear 21 to rotate. Simultaneously, the meshing of the second gear 21 with the first gear ring 20 drives the first gear ring 20 to rotate. This, in turn, the meshing of the first gear ring 20 with the first gear 19 drives the first gear 19 and the second bevel gear 18 to rotate. This, in turn, the meshing of the second bevel gear 18 with the first bevel gear 17 drives the threaded rod 16 to rotate. The threaded engagement of the threaded rod 16 with the positioning block 15 moves the positioning block 15. Thus, after the support cover 5 is inserted into the mounting groove 6, the engagement of the positioning block 15 with the positioning port 13 allows the support cover 5 to move. During the installation and fixing process, the support plate 7 can be pressed against the surface of the activated carbon particles under the action of the support spring 8, thereby fixing the activated carbon particles in conjunction with the support cover 5. Then, the operator fixes the box cover 2 to the box body 1 with bolts, so that the support cover 5 can extend into the box body 1 and seal the box body 1 and the support cover 5 through the sealing ring 24. At this time, exhaust gas is introduced into the box body 1 through the air inlet, so that the exhaust gas can be adsorbed by the activated carbon particles. After the adsorption is completed, the operator closes the first control valve and the second control valve. Then, the operator controls the operation of the microwave generator 11 and the microwave heater 10 to heat the activated carbon particles. At the same time, the vacuum pump 9 can be used to perform vacuum desorption of the activated carbon particles, so that the adsorbed organic pollutants can be desorbed from the surface of the activated carbon particles.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
