Description

Technical Field

[0001] This invention belongs to the field of high-concentration nitrogen-containing organic waste gas treatment technology, specifically, it relates to a catalytic purification device for high-concentration nitrogen-containing organic waste gas. Background Technology

[0002] The main sources of organic waste gas pollution are concentrated in the petroleum and chemical industries. These enterprises generate nitrogen-containing organic waste gases during their production processes due to energy consumption. Once these diverse and high-concentration waste gases enter the atmosphere, they will inevitably impact the surrounding environment and human health. These waste gases require technical treatment to meet emission standards before being released, thereby reducing environmental pollution.

[0003] In the treatment of nitrogen-containing organic waste gases, once the ignition point of the organic matter is reached, high temperatures can effectively decompose and oxidize the nitrogen-containing organic waste gases, making it a relatively efficient method currently used for this purpose. High temperatures can effectively decompose and oxidize nitrogen-containing organic waste gases.

[0004] Thermal destruction treatment directly burns the organic matter in nitrogen-containing organic waste gas, forming water and ordinary gases, thus achieving the purpose of cleaning. Among them, catalytic combustion is more effective, achieving a cleanliness level of over 90% for nitrogen-containing organic waste gas pollution treatment.

[0005] Catalytic combustion requires a precious metal catalyst. A porous ceramic structure coated with alumina is used to attach the precious metal catalyst within the tiny pores of the alumina, increasing the reaction rate and facilitating removal. However, replacing the precious metal catalyst requires shutting down the entire system and lowering the catalytic combustion furnace to room temperature before it can be removed. This method is not only complex but also renders the equipment inoperable, reducing overall efficiency.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0048] A toggle mechanism is provided at one end of the rotating mechanism. The toggle mechanism includes a rotating shaft 500, a first support plate 502 is installed on one side of the rotating shaft 500, and a second support plate 503 is installed at one end of the first support plate 502. The cross-sectional shape of the first support plate 502 and the second support plate 503 is L-shaped. The toggle mechanism is used to toggle the precious metal catalyst carrier 206.

[0049] The top of the mounting opening 102 is provided with a door panel groove 103, and a door panel 300 is movably connected inside the door panel groove 103. A door opening mechanism is provided on one side of the door panel 300. The door opening mechanism includes a stop bar 302 and a pull bar 303. A connecting rod 301 is installed at one end of the stop bar 302, and the other end of the connecting rod 301 is installed at one end of the door panel 300.

[0050] like Figures 1 to 10 As shown, in a specific embodiment, a support block 200 is installed on one side of the mounting plate 101, and a support shaft 201 is installed at one end of the support block 200. Two fixing plates 202 are movably inserted into the support shaft 201, and one end of the door panel 300 is rotatably connected to the top of the support block 200. In this configuration, the door panel 300 rotates and descends under the action of gravity and gets into the door panel groove 103, thereby sealing the mounting opening 102.

[0051] like Figures 1 to 10 As shown, furthermore, baffles 203 are installed between both ends of the two fixing plates 202. One side of the baffle 203 is aligned with the clamping plate 204. The outer end of the clamping plate 204 is arc-shaped with the support shaft 201 as the center. A mating block 104 is installed at one end of the mounting opening 102. One end of the mating block 104 is adapted to the arc shape of the outer end of the clamping plate 204. A groove 205 is provided on the side of the clamping plate 204. In this configuration, the baffles 203 abut against the top precious metal catalyst carrier 206 to prevent it from falling off.

[0052] like Figures 1 to 10 As shown, furthermore, a support plate 208 is provided at the bottom between the two fixed plates 202. A support plate 207 is installed at one end of the support plate 208, and the other end of the support plate 207 is installed on one side of the mounting plate 101. The cross-sectional shape of the support plate 208 is arc-shaped, and the tops of both ends of the support plate 208 are rounded. In this configuration, the support plate 208 abuts against the precious metal catalyst carrier 206 at the bottom to prevent it from falling off.

[0053] Example 2:

[0054] like Figures 1 to 10As shown, in a specific embodiment, a support rod 400 is installed on one side of the mounting plate 101. Two sliding shafts 401 are installed on the side of the support rod 400 near the guide block 406. The same slider 402 is movably sleeved on the two sliding shafts 401. A vertical plate 403 and a vertical rod 404 are respectively installed on the slider 402. The height of the vertical plate 403 is greater than that of the vertical rod 404, and the distance between the vertical plate 403 and the mounting plate 101 is less than the distance between the vertical rod 404 and the mounting plate 101. The two ends of the two guide rods 405 are respectively installed on one side of the vertical plate 403 and the vertical rod 404. In this configuration, the lower inclined surface 407 on one side of the guide block 406 abuts against the push rod 409, causing it to rotate. When the push rod 409 rotates at a certain angle, since the guide rod 405 is in an inclined state, the guide block 406 descends during the movement, causing the upper inclined surface 408 of the guide block 406 to contact the push rod 409, and driving the push rod 409 to continue rotating until the top of the guide block 406 separates from the push rod 409. At this time, the push rod 409 rotates 180 degrees.

[0055] like Figures 1 to 10 As shown, further, a connecting block 410 is installed at the end of the upright plate 403 away from the guide rod 405. The bottom of the connecting block 410 is installed at the top of the slider 402. The pull rod 303 has an L-shaped cross-section, and the other end of the pull rod 303 is installed at the top of the connecting block 410. A limit sleeve 304 is movably sleeved on the pull rod 303, and one side of the limit sleeve 304 is installed on one side of the mounting plate 101. In this configuration, when the connecting block 410 moves, it pulls the pull rod 303. The other end of the pull rod 303 abuts against the stop rod 302, and the stop rod 302 drives the door panel 300 to rotate and open through the connecting rod 301.

[0056] Example 3:

[0057] like Figures 1 to 10 As shown, in a specific embodiment, both ends of the rotating shaft 500 movably pass through the mounting plate 101. One end of the rotating shaft 500 is rotatably connected to a steering shaft 504, and the other end of the steering shaft 504 is rotatably connected to a push rod 505. The rotation directions of the two ends of the steering shaft 504 are perpendicular to each other, and the other end of the push rod 505 is rotatably connected to the outside of the guide block 406. In this configuration, by pushing the rotating shaft 500 with a handle, the rotating shaft 500 abuts against the push rod 505, and one end of the push rod 505 abuts against the guide block 406.

[0058] like Figures 1 to 10As shown, further, a first slot 600 is provided on one side of the mounting plate 101, and a second slot 601 is provided on the top of the first slot 600. A limit groove 501 is provided on the rotating shaft 500. A gear 603 is movably sleeved on the rotating shaft 500. A rack 602 is meshed with the top of the gear 603. The top of the rack 602 is fixedly installed on the bottom of the second slot 601. The width of the rack 602 is adapted to the width of the gear 603. An outer clamping block 604 and an inner clamping block 605 are respectively installed on the sides of the first slot 600 and the second slot 601. The distance between the outer clamping block 604 and the inner clamping block 605 is adapted to the width of the gear 603. A sleeve 506 is movably sleeved on the rotating shaft 500. The inner wall shape of the sleeve 506 is adapted to the outer wall shape of the rotating shaft 500. The sleeve 506 is rotatably connected inside the connecting block 410. In this setup, rotating the handle causes the rotating shaft 500 to rotate, which in turn drives the gear 603 to rotate. As the gear 603 rotates, it achieves displacement through meshing with the rack 602, and also moves the connecting block 410.

[0059] The implementation principle of a high-concentration nitrogen-containing organic waste gas catalytic purification device in this embodiment is as follows: When replacing the precious metal catalyst, the precious metal catalyst carrier 206 needs to be removed. Due to the different positions of the clamping plates 204 on both sides, the precious metal catalyst closer to the inside of the catalytic combustion chamber 100 is consumed in greater quantities. Therefore, the precious metal catalyst inside should be replaced first. By pushing the rotating shaft 500 with the handle, the rotating shaft 500 abuts against the top rod 505. One end of the top rod 505 abuts against the guide block 406. At this time, the lower inclined surface 407 on one side of the guide block 406 abuts against the push rod 409, thereby causing it to rotate. When the push rod 409 rotates at a certain angle, due to the guide rod 409... 5 is in an inclined state. During movement, the guide block 406 descends, causing its upper inclined surface 408 to contact the push rod 409, which in turn drives the push rod 409 to continue rotating until the top of the guide block 406 separates from the push rod 409. At this point, the push rod 409 rotates 180 degrees, causing the fixing plate 202 to rotate 180 degrees. The fixing plate 202 drives the clamping plate 204 to rotate, thereby swapping the positions of the precious metal catalyst carriers 206 on both sides. When the clamping plate 204 rotates, the support plate 208 abuts against the bottom precious metal catalyst carrier 206 to prevent it from falling, and the baffle plate 203 abuts against the top precious metal catalyst carrier 206 to prevent it from falling. At this time, the rotation... The handle causes the rotating shaft 500 to rotate, which in turn drives the gear 603 to rotate. As the gear 603 rotates, it meshes with the rack 602 to achieve displacement, which in turn moves the connecting block 410. The connecting block 410 then moves the slider 402, causing the guide block 406 to move and disengage from the push rod 409. When the connecting block 410 moves, it pulls the pull rod 303. The other end of the pull rod 303 abuts against the stop rod 302. The stop rod 302, through the connecting rod 301, causes the door panel 300 to rotate and open. Simultaneously, the rotation of the rotating shaft 500 causes the first support plate 502 to rotate, which in turn causes the second support plate 503 to engage with the precious metal catalyst carrier 206. On one side, pull the handle to move the rotating shaft 500 outward, and the precious metal catalyst carrier 206 can be pulled out through the first support plate 502 and the second support plate 503. Keep the position of the rotating shaft 500 unchanged, put the new precious metal catalyst carrier 206 into the clamping plate 204, and rotate the rotating shaft 500 in the opposite direction. At this time, the slider 402 and the connecting block 410 are reset through the meshing of the gear 603 and the rack 602, and the guide block 406 is placed on one side of the push rod 409. At the same time, the reset of the connecting block 410 drives the pull rod 303 to move. At this time, the door panel 300 rotates and descends under the action of gravity and gets stuck in the door panel groove 103, thereby sealing the installation port 102.
