Description

Technical Field

[0002] A zeolite rotary wheel is a device that concentrates waste gas with a large air volume and low concentration into waste gas with a high concentration and small air volume, thereby reducing the equipment investment cost and operation cost and improving the high-efficiency treatment of organic waste gas; when burning and recovering waste gas with a large air volume and low concentration, if no concentration is carried out and direct burning is carried out, the waste gas treatment equipment is not only huge in volume, but also the generated operation cost will be very large. The patent with the authorization announcement number CN220257553U: "An Organic Waste Gas Concentration Device", discloses a device for facilitating the concentration of organic waste gas in this patent. However, when this device is in use, the conveying air duct is communicated with the device main body, and the untreated waste gas is likely to directly discharge to the outside through the conveying air duct, affecting the concentration of the waste gas. At the same time, part of the hot air is likely to directly discharge to the outside through the air outlet after discharging from the air outlet pipe and cannot contact the organic waste gas on the zeolite, affecting the concentration of the waste gas. Therefore, we have designed a concentration mechanism for organic waste gas that can ensure the waste gas concentration efficiency. Content of the Utility Model

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] A concentration mechanism for organic waste gas, such as Figure 1 , 2, as shown in Figures 3, it includes a short tube 5. Inside the short tube 5, a zeolite rotor 10 is rotatably arranged. The zeolite rotor 10 includes an outer tube 6. Inside the outer tube 6, an inner tube 7 is arranged. The inner tube 7, the outer tube 6, and the short tube 5 are coaxially arranged. The outer tube 6 and the inner tube 7 are fixedly connected by several partition plates 8. The width of the cross plate 8 is shorter than the widths of the inner tube 7 and the outer tube 6. The zeolite module 9 is fixedly installed between several partition plates 8. The width of the zeolite module 9 is the same as the width of the partition plate 8. Inside the short tube 5, there is a driving device capable of driving the zeolite rotor 10 to rotate. Inside the short tube 5, there are a hot air inlet pipe 16 and a hot air outlet pipe 17. Inside the hot air inlet pipe 16, a hot air blower 22 is fixedly installed. It is characterized in that: on both sides of the outer tube 6, there are respectively sector plates 11. The sector plates 11 are located in the upper half of the outer tube 6 and are coaxially arranged with the outer tube 6. The sector plates 11 are respectively fixedly installed on the short tube 5. On the sides of the sector plates 11 that are close to each other, there are respectively fixedly installed a first arc plate 12, a second arc plate 13, a third arc plate 14, and a fourth arc plate 15. The sector plates 11, the first arc plate 12, the second arc plate 13, the third arc plate 14, and the fourth arc plate 15 are coaxially arranged with the inner tube 7. The first arc plate 12, the second arc plate 13, the third arc plate 14, and the fourth arc plate 15 are in sliding contact and cooperation with the outer circumference and inner circumference of the outer tube 6 and the inner tube 7 in sequence. The inner side of the first arc plate 12 is in sliding contact and cooperation with the outer side of the outer tube 6. The outer side of the second arc plate 13 is in sliding contact and cooperation with the inner side of the outer tube 6. The inner side of the third arc plate 14 is in sliding contact and cooperation with the outer side of the inner tube 7. The outer side of the fourth arc plate 15 is in sliding contact and cooperation with the inner side of the inner tube 7. On both sides of the corresponding second arc plate 13 and third arc plate 14, there are fixedly installed support shafts 18. On the support shafts 18, several coaxial rotating wheels 19 are rotatably installed. The rotating wheels 19 are in frictional contact and cooperation with the sector plates 11, the partition plates 8, and the zeolite module 9. Between adjacent rotating wheels 19, there is sliding frictional contact and cooperation. The two sector plates 11, the first arc plate 12, the second arc plate 13, the third arc plate 14, the fourth arc plate 15, the outer tube 6, and the inner tube 7 form a cavity 21. The hot air inlet pipe 16 and the hot air outlet pipe 17 are communicated with the cavity 21. One ends of the hot air inlet pipe 16 and the hot air outlet pipe 17 are both fixedly installed on the sector plates 11. On the sector plates 11, there are reserved holes corresponding to the hot air inlet pipe 16 and the hot air outlet pipe 17. The hot air inlet pipe 16 and the hot air outlet pipe 17 are communicated with the cavity 21 through the corresponding reserved holes. The structure of the utility model is simple and ingenious. When hot air is introduced into the cavity 21, it can ensure that the hot air contacts the zeolite module 9 to concentrate the waste gas. At the same time, the waste gas can only be discharged to the outside through the air outlet pipe 4 after being concentrated, which can ensure the concentration efficiency of the waste gas. At the same time, the rotating wheels 19 can ensure the sealing performance of the cavity 21. Since the frictional force of rolling friction is less than that of sliding friction, compared with directly using fixed plates to form the cavity 21, using the rotating wheels 19 can reduce the loss of the partition plates 8 and the zeolite module 9, can meet the actual requirements, and is suitable for popularization.When the present utility model is used, the control driving device drives the zeolite rotary wheel 10 to rotate. Since the rotating wheel 19 is in frictional contact and cooperation with the partition plate 8 and the zeolite module 9, as the partition plate 8 and the zeolite module 9 rotate, the rotating wheel 19 rotates on the corresponding support shaft 18. While ensuring the airtightness of the cavity 21, the frictional force between the partition plate 8 and the zeolite module 9 can be reduced to the minimum, reducing the loss caused by friction to the partition plate 8 and the zeolite module 9. At this time, waste gas is introduced into the short pipe 5, and at the same time, the hot air blower 22 is started. The hot air blower 22 heats the air, and hot air is discharged into the cavity 21 through the hot air inlet pipe 16. When the waste gas passes through the zeolite rotary wheel 10, it is adsorbed on the zeolite module 9. As the zeolite rotary wheel 10 rotates, the zeolite module 9 adsorbed with waste gas rotates into the cavity 21, and the hot air desorbs and concentrates the waste gas. After the desorbed and concentrated organic waste gas is removed from the cavity 21, it is discharged from the short pipe 5, and the hot air is discharged from the hot air outlet pipe 17.

[0019] Specifically, as shown in the figure, the short pipe 5 in this embodiment is fixedly installed in the tank body 1. The outer periphery of the short pipe 5 is fixedly connected to the inner wall of the tank body 1. The short pipe 5 and the tank body 1 are coaxially arranged. Several support legs 2 are fixedly installed at the bottom of the tank body 1. The air inlet pipe 3 and the air outlet pipe 4 are sequentially connected and installed at the left and right ends of the tank body 1. The hot air inlet pipe 16 and the hot air outlet pipe 17 are both fixedly installed in the tank body 1 and communicate with the outside. An initial filter 20 is fixedly provided on the left side of the tank body 1, and the initial filter 20 is fixedly installed in the tank body 1. The control driving device drives the zeolite rotary wheel 10 to rotate. By introducing air through the hot air inlet pipe 16, the hot air blower 22 heats the air and blows out hot air. When in use, the waste gas is introduced through the air inlet pipe 3, and the initial filter 20 can filter out larger dust in the organic waste gas. After the filtered waste gas contacts the zeolite module 9, the hot air enters the cavity 21. As the zeolite rotary wheel 10 rotates, the zeolite module 9 adsorbed with waste gas enters the cavity 21, and the hot air contacts the waste gas in the zeolite module 9, and the waste gas is desorbed and concentrated. After the desorbed and concentrated waste gas is removed from the cavity 21, it is discharged from the air outlet pipe 4.

[0020] Specifically, as shown in the figure, a medium filter 30 is fixedly provided on the right side of the initial filter 20 in this embodiment, and the medium filter 30 is fixedly installed in the tank body 1. The medium filter 30 can further filter out smaller dust in the organic waste gas.

[0021] Specifically, as shown in the figure, an activated carbon plate 40 is fixedly provided on the right side of the medium filter 30 in this embodiment, and the activated carbon plate 40 is fixedly installed inside the tank body 1. The activated carbon plate 40 can adsorb high-boiling substances in the waste gas and better protect the adsorption efficiency of the zeolite.

[0022] Specifically, as shown in the figure, the driving device in this embodiment includes a horizontal shaft 50. The horizontal shaft 50 is fixedly installed in the inner tube 7. The horizontal shaft 50 is coaxially arranged with the inner tube 7. Both ends of the horizontal shaft 50 are rotatably installed in the short tube 5 through shaft seats. One end of the horizontal shaft 50 is fixedly installed with a coaxial first bevel gear 51. A second bevel gear 52 is meshed and cooperated on one side of the first bevel gear 51. The axis of the first bevel gear 51 is perpendicular to the axis of the second bevel gear 52. The second bevel gear 52 is fixedly installed on the vertical shaft 53. One end of the vertical shaft 53 extends out of the short tube 5 and the tank body 1. The short tube 5 and the tank body 1 are respectively provided with reserved holes. The vertical shaft 53 is rotatably installed in the corresponding reserved holes through sealed bearings. A motor 54 is fixedly installed at the bottom of the tank body 1. The output shaft of the motor 54 is coaxial and fixedly connected with the vertical shaft 53. When the motor 54 is started, the output shaft of the motor 54 drives the vertical shaft 53 to rotate. The vertical shaft 53 rotates through the second bevel gear 52. The second bevel gear 52 drives the first bevel gear 51 to rotate. The first bevel gear 51 drives the inner tube 7 to rotate through the horizontal shaft 50. The inner tube 7 drives the partition plate 8, the outer tube 6, and the zeolite module 9 to rotate.

[0023] Further, as shown in the figure, on one side of the rotating wheels 19 close to each other, baffles 60 are provided. The baffles 60 are located in the cavity 21. The baffles 60 are fixedly installed on the corresponding second arc-shaped plates 13, third arc-shaped plates 14, and sector plates 11. The side edges of the baffles 60 are fixedly connected to one side of the corresponding second arc-shaped plates 13, third arc-shaped plates 14, and sector plates 11 in sequence. One side of the baffles 60 is in sliding contact and cooperation with the partition plate 8 and the zeolite module 9. Both the baffles 60 and the rotating wheels 19 can be in sliding contact and cooperation with the partition plate 8 and the zeolite module 9, which can further increase the sealing performance of the cavity 21 and reduce the possibility of hot air escaping from the cavity 21.

[0024] Further, as shown in the figure, an annular slider 70 is fixedly installed in the short tube 5. An annular sliding groove 71 is opened on the outer tube 6 corresponding to the annular slider 70. The annular slider 70 is slidably installed in the annular sliding groove 71. The annular sliding groove 71, the annular slider 70, the short tube 5, and the outer tube 6 are coaxially arranged. When the outer tube 6 rotates, the annular slider 70 can slide in the corresponding annular sliding groove 71, which can reduce the possibility that the waste gas passes through the gap between the short tube 5 and the outer tube 6 without passing through desorption and concentration.

[0025] Furthermore, as shown in the figure, several fixing rings 80 are fixedly installed on the outer periphery of the outer tube 6. In this embodiment, there are two fixing rings 80. The fixing rings 80 are in sliding contact and cooperation with the short tube 5. When the outer tube 6 rotates, the fixing rings 80 can be in sliding contact and cooperation with the short tube 5, which can further reduce the possibility that the waste gas directly passes through the gap between the short tube 5 and the outer tube 6 without desorption and concentration.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
