Description

Technical Field

[0001] This application relates to the technical field of flue gas filtration, and more particularly to a flue gas treatment device and its treatment process based on a dust collector. Background Technology

[0002] Minerals undergo processes such as dehydration, decomposition, oxidation, reduction, chlorination, sulfation, agglomeration, or pelletizing when subjected to temperatures below their melting point. During mineral processing, harmful impurities, moisture, and other volatile components can be removed. The flue gas generated during mineral processing rises naturally, carrying these harmful impurities, moisture, and volatile components with it, and is discharged from the exhaust port. If this flue gas containing impurities is directly released into the air, it will cause air pollution. Therefore, a filtration device is needed to filter the gas before discharge to reduce air pollution.

[0017] This application discloses a flue gas treatment device and its processing technology based on a dust collector, which uses two flue gas channels to filter the flue gas sequentially. As dust is collected, when the number of filter holes on the filter plate becomes blocked reaches a preset value, it will overcome friction and rotate, thereby exposing the filter cartridge in the other flue gas treatment channel. This serves two purposes: firstly, it indicates that the filter plate in the current flue gas treatment channel has accumulated a large amount of dust and its effective filtration time is insufficient, thus allowing for timely replacement of the filter plate in the other flue gas treatment channel; secondly, it exposes the filter cartridge in the other flue gas treatment channel, making it easier to remove the filter cartridge.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Example 1, refer to Figures 1 to 6 The present invention provides a flue gas treatment device based on a dust collector, including a first flue gas channel 1 and a second flue gas channel 2 in parallel. The first flue gas channel 1 and the second flue gas channel 2 filter the flue gas in sequence. An adjusting motor 5 is provided at the air inlet end of the first flue gas channel 1. The output shaft of the adjusting motor 5 is connected to an adjusting plate 6. The flue gas inlet channel is installed on the adjusting plate 6. When the adjusting motor 5 is working, it drives the flue gas inlet channel to connect with the first flue gas channel 1 or with the second flue gas channel 2.

[0020] Based on the above configuration, the flue gas treatment device in this embodiment has two flue gas treatment channels, which perform flue gas treatment sequentially.

[0021] Specifically, refer to Figure 3 A first filter cylinder 11 is slidably disposed in the first flue gas channel 1, and a spiral first filter element 111 is disposed in the first filter cylinder 11. A second filter cylinder 21 is slidably disposed in the second flue gas channel 2, and a spiral second filter element 211 is disposed in the second filter cylinder 21.

[0022] With the above settings, when the first flue gas channel 1 is used for flue gas treatment, the filter holes on the first filter 111 are gradually blocked by smoke and dust. When the number of filter holes blocked on the first filter 111 reaches a preset value, the first filter 111 will overcome the friction and rotate, thereby driving the second filter cartridge 21 to slide and be exposed in the second flue gas channel 2, so as to facilitate the replacement of the second filter cartridge 21.

[0023] When using the second flue gas channel 2 for flue gas treatment, the filter holes on the second filter 211 are gradually blocked by smoke and dust. When the number of filter holes blocked on the second filter 211 reaches a preset value, the second filter 211 will overcome the friction and rotate, thereby driving the first filter cartridge 11 to slide and be exposed in the first flue gas channel 1, so as to facilitate the replacement of the first filter cartridge 11.

[0024] Therefore, in this embodiment, when the flue gas treatment device uses one of the flue gas treatment channels, as the dust is collected, when the number of filter holes on the filter plate that are blocked reaches a preset value, it will overcome friction and rotate, thereby driving the filter cartridge in the other flue gas treatment channel to be exposed. On the one hand, this can indicate that the filter plate in the current flue gas treatment channel has accumulated a lot of dust and its effective filtration time is not long enough, so the filter plate in the other flue gas treatment channel can be replaced in time. On the other hand, it can also expose the filter cartridge in the other flue gas treatment channel, so that the filter cartridge can be easily removed and replaced.

[0025] Specifically, refer to Figure 2 The first flue gas passage 1 includes a first sliding part 101 and a first driving part 102. The first sliding part 101 is used to accommodate the first filter cylinder 11. A first fixing rod 103 is arranged along the axis inside the first sliding part 101. The first filter cylinder 11 includes a cylindrical first cylinder 112. A first sliding strip 113 is arranged on the outer wall of the first cylinder 112. A first sliding groove 114 corresponding to the first sliding strip 113 is arranged on the inner wall of the first sliding part 101. The first sliding strip 113 is movably arranged in the first sliding groove 114.

[0026] Furthermore, referring to Figure 3The inner walls of the first cylinder 112 are respectively provided with a first annular groove 115 and a second annular groove 116 at both ends. A first fixing ring 117 and a second fixing ring 118 are rotatably arranged in the first annular groove 115 and the second annular groove 116, respectively. A first sleeve 119 is connected between the first fixing ring 117 and the second fixing ring 118. The inner wall of the first fixing ring 117 is connected to the first sleeve 119 through a bracket. The inner wall of the second fixing ring 118 is connected to the first sleeve 119 through a bracket. The first sleeve 119 is rotatably sleeved on the outside of the first fixing rod 103. The first filter 111 is spirally arranged on the first sleeve 119. The end of the first sleeve 119 extends into the first driving part 102, and a first driving gear 1110 is provided at the end of the first sleeve 119.

[0027] Similarly, refer to Figure 2 The second flue gas passage 2 includes a second sliding part 201 and a second driving part 202.

The second filter cylinder 21 includes a cylindrical second cylinder 212. A second sliding strip 213 is arranged on the outer wall of the second cylinder 212. A second sliding groove 214 corresponding to the second sliding strip 213 is arranged on the inner wall of the second sliding part 201. The second sliding strip 213 is movably arranged in the second sliding groove 214.

[0028] Furthermore, referring to Figure 3 The inner walls of the second cylinder 212 are respectively provided with a third annular groove 215 and a fourth annular groove 216 at both ends. A third fixed ring 217 and a fourth fixed ring 218 are rotatably arranged in the third annular groove 215 and the fourth annular groove 216, respectively. A second sleeve 219 is connected between the third fixed ring 217 and the fourth fixed ring 218. The inner wall of the third fixed ring 217 is connected to the second sleeve 219 through a bracket. The inner wall of the fourth fixed ring 218 is connected to the second sleeve 219 through a bracket. The second sleeve 219 is rotatably sleeved on the outside of the second fixed rod 203. The second filter 211 is spirally arranged on the second sleeve 219. The end of the second sleeve 219 extends into the second drive part 202, and a second drive gear 2110 is provided at the end of the second sleeve 219.

[0029] It should also be noted that, referring to Figure 2 A first transmission rod 3 and a second transmission rod 4 are provided between the first drive unit 102 and the second drive unit 202. The starting end of the first transmission rod 3 extends into the first drive unit 102 and is provided with a first transmission gear 301. The first transmission gear 301 meshes with the first drive gear 1110.

[0030] Among them, reference Figure 5 and Figure 6The end of the first transmission rod 3 extends into the second drive part 202 and is provided with a second transmission gear 302. The second drive part 202 is provided with a second drive groove 303. A second sliding rod 304 is slidably arranged in the second drive groove 303. A second drive rack 305 is provided on the rod body of the second sliding rod 304. The second sliding rod 304 is connected to a second push seat 306 for pushing the second filter cylinder 21. The second transmission gear 302 is connected to the second drive rack 305 in a transmission connection.

[0031] Similarly, refer to Figure 5 and Figure 6 The starting end of the second transmission rod 4 extends into the second drive part 202 and is provided with a third transmission gear 401. The third transmission gear 401 meshes with the second drive gear 2110. The end of the second transmission rod 4 extends into the first drive part 102 and is provided with a fourth transmission gear 402. The first drive part 102 is provided with a first drive groove 403. A first sliding rod 404 is slidably disposed in the first drive groove 403. A first drive rack 405 is disposed on the rod body of the first sliding rod 404. The first sliding rod 404 is connected to a first push seat 406 for pushing the first filter cylinder 11. The fourth transmission gear 402 is connected to the first drive rack 405 in a transmission connection.

[0032] When using the flue gas treatment device in this embodiment, the flue gas inlet channel is first connected to the first flue gas channel 1 by adjusting the motor 5, and the flue gas is treated by the first flue gas channel 1 (after long-term operation and multiple channel switching, the second flue gas channel 2 is blocked and the second filter cartridge 21 needs to be replaced).

[0033] In the first flue gas passage 1, there is significant friction between the first fixed ring 117 and the first annular groove 115, and between the second fixed ring 118 and the second annular groove 116. Therefore, under normal conditions, the first fixed ring 117 does not rotate, meaning the first filter element 111 is in a fixed state. After flue gas enters the first flue gas passage 1, it passes through the filter holes on the first filter element 111. Some dust falls into the filter holes, causing them to gradually become clogged. After the filter holes on the first filter element 111 become clogged, because the first filter element 111 is in a spiral state, it is impacted by the airflow and tends to rotate. This tendency increases as the filter holes become clogged. Once the number of clogged filter holes on the first filter element 111 reaches a preset value, the first filter element 111 overcomes the friction exerted by the first annular groove 115 and the second annular groove 116 and begins to rotate.

[0034] The rotation of the first filter element 111 causes the first sleeve 119 to rotate, which in turn drives the first drive gear 1110 to rotate. The first drive gear 1110 drives the first transmission gear 301 to rotate, which in turn causes the first transmission rod 3 and the second transmission gear 302 to rotate. The second transmission gear 302 drives the second drive rack 305 to move, which in turn causes the second sliding rod 304 and the second push seat 306 to move, which in turn pushes the second filter cylinder 21 to move, so that the left end of the second filter cylinder 21 is exposed in the second cylinder body 212, which provides a prompt for replacing the second filter cylinder 21 and facilitates the removal of the second filter cylinder 21.

[0035] When switching flue gas channels, the flue gas inlet channel is connected to the second flue gas channel 2 by adjusting the motor 5, and the flue gas is treated by the second flue gas channel 2. When switching flue gas channels, the second filter cartridge 21 is manually pushed in to reset the second filter cartridge 21.

[0036] In the second flue gas passage 2, there is significant friction between the third fixed ring 217 and the third annular groove 215, and between the fourth fixed ring 218 and the fourth annular groove 216. Therefore, under normal conditions, the third fixed ring 217 does not rotate, meaning the second filter plate 211 is in a fixed state. After flue gas enters the second flue gas passage 2, it passes through the filter holes on the second filter plate 211. Some dust falls into the filter holes, causing them to gradually become clogged. When the filter holes on the second filter plate 211 become clogged, because the second filter plate 211 is spiral-shaped, it is impacted by the airflow and tends to rotate, with this tendency increasing as the blockage increases. Once the number of clogged filter holes on the second filter plate 211 reaches a preset value, the second filter plate 211 overcomes the friction exerted by the third annular groove 215 and the fourth annular groove 216 and begins to rotate.

[0037] The rotation of the second filter element 211 causes the second sleeve 219 to rotate, which in turn drives the second drive gear 2110 to rotate. The second drive gear 2110 drives the third transmission gear 401 to rotate, which in turn drives the second transmission rod 4 and the fourth transmission gear 402 to rotate. The fourth transmission gear 402 drives the first drive rack 405 to move, which in turn moves the first sliding rod 404 and the first push seat 406, thereby pushing the first filter cylinder 11 to move, so that the left end of the first filter cylinder 11 is exposed in the first cylinder body 112, which provides a prompt for replacing the first filter cylinder 11 and facilitates the removal of the first filter cylinder 11.

[0038] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: This embodiment uses a first flue gas channel 1 and a second flue gas channel 2 to filter the flue gas sequentially. As dust accumulates, when the number of filter holes on the filter plate becomes clogged reaches a preset value, it will overcome friction and rotate, thereby exposing the filter cartridge in the other flue gas treatment channel. This serves two purposes: firstly, it indicates that the filter plate in the current flue gas treatment channel has accumulated a large amount of dust, and its effective filtration time is insufficient, thus requiring timely replacement of the filter plate in the other flue gas treatment channel; secondly, it exposes the filter cartridge in the other flue gas treatment channel, making it easier to remove the filter cartridge.

[0039] Example 2 The present invention provides a flue gas treatment process based on a dust collector, comprising the following steps: S1. Switch the flue gas passage. The flue gas inlet passage is connected to the first flue gas passage 1, and the flue gas is treated by the first flue gas passage 1. S2. After the flue gas enters the first flue gas channel 1, it passes through the filter holes on the first filter plate 111. Some dust falls into the filter holes, causing them to gradually become clogged. Because the first filter plate 111 is spiral-shaped, it is impacted by the airflow and tends to rotate, with this tendency increasing as the filter becomes clogged. Once the number of clogged filter holes on the first filter plate 111 reaches a preset value, the first filter plate 111 overcomes the frictional force applied by the first annular groove 115 and the second annular groove 116, and rotates. S3. The rotation of the first filter element 111 drives the first sleeve 119 to rotate, which in turn drives the first drive gear 1110 to rotate. The first drive gear 1110 drives the first transmission gear 301 to rotate, which in turn drives the first transmission rod 3 and the second transmission gear 302 to rotate. The second transmission gear 302 drives the second drive rack 305 to move, which in turn moves the second sliding rod 304 and the second push seat 306, which in turn pushes the second filter cylinder 21 to move, so that the left end of the second filter cylinder 21 is exposed in the second cylinder body 212, which provides a prompt for replacing the second filter cylinder 21 and facilitates the removal of the second filter cylinder 21. S4. Switch the flue gas channel. The flue gas inlet channel is connected to the second flue gas channel 2. The flue gas is treated by the second flue gas channel 2. When switching the flue gas channel, manually push the second filter cartridge 21 in to reset the second filter cartridge 21. S5. After the flue gas enters the second flue gas passage 2, it passes through the filter holes on the second filter plate 211. Some dust falls into the filter holes, causing them to gradually become clogged. Because the second filter plate 211 is spiral-shaped, it is impacted by the airflow and tends to rotate, with this tendency increasing as the filter becomes clogged. Once the number of clogged filter holes on the second filter plate 211 reaches a preset value, the second filter plate 211 overcomes the frictional force exerted by the third annular groove 215 and the fourth annular groove 216, and rotates.

[0040] S6. The rotation of the second filter element 211 drives the second sleeve 219 to rotate, which in turn drives the second drive gear 2110 to rotate. The second drive gear 2110 drives the third transmission gear 401 to rotate, which in turn drives the second transmission rod 4 and the fourth transmission gear 402 to rotate. The fourth transmission gear 402 drives the first drive rack 405 to move, which in turn moves the first sliding rod 404 and the first push seat 406, which in turn pushes the first filter cylinder 11 to move, so that the left end of the first filter cylinder 11 is exposed in the first cylinder body 112, which provides a prompt for replacing the first filter cylinder 11 and facilitates the removal of the first filter cylinder 11. S7. Switch the flue gas channel. The flue gas inlet channel is connected to the first flue gas channel 1. The flue gas is treated by the first flue gas channel 1. When switching the flue gas channel, manually push the first filter cartridge 11 in to reset the first filter cartridge 11. S8. Repeat steps S2-S7.
