[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 One embodiment of the present invention provides a flue gas dust removal device for air pollution control, comprising a first loading box 1.

[0031] A smoke inlet pipe 2 is provided on one side of the first loading box 1, a second loading frame 3 is provided on one side of the smoke inlet pipe 2, a smoke outlet pipe 4 is provided on the second loading frame 3, and a filter loading cylinder 5 is provided on the smoke outlet pipe 4.

[0032] A filter layer filtration mechanism is installed inside the first loading box 1 and is used for preliminary filtration of flue gas.

[0033] A hydrolysis filtration mechanism is installed inside the second loading frame 3. The hydrolysis filtration mechanism is used to filter the flue gas again.

[0034] The adsorption filtration mechanism is installed inside the filter loading cylinder 5. The adsorption filtration mechanism is used for the final filtration of flue gas. This equipment uses three different filtration methods to increase the efficiency and adaptability of the equipment for flue gas treatment. In addition, an adjustable filter layer filtration mechanism is also provided to increase the filtration efficiency for flue gas with different flow rates.

[0035] Furthermore, the filter layer filtration mechanism includes two sets of movable plates 6, which are symmetrically and movably arranged within the first loading box 1. Filter layers 7 are movably connected between the movable plates 6. Three sets of sliders 8 are provided at the lower end of each movable plate 6. Three sets of sliding grooves 9 are provided inside the lower end of the first loading box 1. A screw sleeve 10 is fixedly installed inside the middle slider 8, and the screw sleeve 10 is threaded onto a bidirectional screw 11. A knob 12 is fixedly installed at one end of the bidirectional screw 11. Limiting rods 13 are fixedly installed in the sliding grooves 9 on both sides, and the sliders 8 are movably sleeved onto the limiting rods 13. T-slots 14 are arrayed on opposite sides of the movable plates 6. The two sets of filter layers 7 are hinged together, and a T-block 15 is hinged to one end of each filter layer 7. The T-block 15 is movably inserted into the T-slot 14. The two sets of movable plates 6 are in their farthest relative position, and the hinged filter layers 7 protrude forward, as shown in the image. Figure 3 , Figure 4 , Figure 5 as well as Figure 7 As shown, this structure allows the filter layer 7 to not only filter the flue gas, but also to adjust the spacing, so that even when the space where the flue gas is diffused becomes smaller and the pressure of the flue gas in the first loading box 1 increases, the filtration effect of the filter layer 7 remains unchanged, increasing the adaptability of the equipment during use.

[0036] Furthermore, the T-slots 14 on the movable plate 6 are of inconsistent lengths and are distributed with varying lengths. The height difference between the T-slots 14 of different lengths is less than one centimeter. Figure 4 As shown, this structure allows space between different filter layers 7, so that when a set of filter layers 7 is blocked, there will be no situation where the flow cannot be completely stopped.

[0037] Furthermore, rubber pads 16 are fixedly installed at the ends of the movable plate 6, and rubber sheets 17 are provided on the rubber pads 16. The rubber sheets 17 are elastic and fit tightly against the two sides of the interior of the first loading box 1, such as... Figure 3 As shown, this structure ensures the sealing of the movable plate 6 when it is adjusted, increasing the stability of the equipment during use.

[0038] Furthermore, a loading box cover 18 is movably disposed on the upper side of the first loading box 1, and a sealing ring 19 is slidably installed on the lower side of the loading box cover 18. The sealing ring 19 is tightly fitted to the upper edge of the first loading box 1. A sealing block 20 is disposed on the lower side of the loading box cover 18. The shape and position of the sealing block 20 correspond to the longer T-slot 14, and the sealing block 20 abuts against the T-block 15. Two sets of cloth strips 21 are symmetrically disposed on the front and rear sides of the loading box cover 18, and three sets of iron rings 22 are arrayed on the cloth strips 21. Two sets of limiting rollers 23 are symmetrically disposed on the front and rear sides of the first loading box 1, and the cloth strips 21 are hung on the limiting rollers 23. Figure 2 As shown, this structure allows the loading box cover 18 to seal the first loading box 1, and the cloth strip 21 loading method has fewer failures and better adaptability, increasing the stability of the equipment during use.

[0039] Furthermore, the hydrolysis filtration mechanism includes a connecting pipe 24, which is connected to one end of the first loading box 1. The connecting pipe 24 is located inside the second loading frame 3. A diversion plate 25 is fixedly installed on the lower side of the second loading frame 3. Diversion holes 26 are arrayed on the diversion plate 25. The lower end of the connecting pipe 24 is inserted into the diversion plate 25. A water inlet pipe 27 is fixedly installed on the upper end of one side of the second loading frame 3. A threaded water plug 28 is installed on the water inlet pipe 27. A drain hole is opened on one end of the second loading frame 3, and a threaded water plug 28 is installed in the drain hole. Figure 5 As shown, this structure allows flue gas to be filtered by hydrolysis, increasing the filtration methods available for the equipment.

[0040] Furthermore, the sizes of the diversion orifices 26 are inconsistent; the diversion orifices 26 closer to the connecting pipe 24 have smaller diameters, while the diversion orifices 26 farther from the connecting pipe 24 have larger diameters. Figure 5 As shown, this structure allows the flue gas to be separated by the diversion holes 26, enabling it to rise evenly and increasing the efficiency of the equipment's hydrolysis.

[0041] Furthermore, the upper end of the water inlet pipe 27 extends beyond the upper end of the second loading frame 3, and the smoke outlet pipe 4 is made of transparent material, such as... Figure 5 As shown, this structure allows for convenient filling of the hydrolyzed material in the second loading frame 3, and the hydrolysis rate can be observed through the smoke outlet pipe 4, increasing the practicality of the equipment during use.

[0042] Furthermore, the adsorption filtration mechanism includes a threaded ring 29, which is fixedly installed at the lower end of the filter loading cylinder 5. A threaded ring 30 is provided at the upper end of the smoke outlet pipe 4. The filter loading cylinder 5 is fixed to the smoke outlet pipe 4 via the threaded ring 29 and the threaded ring 30. A graphite filter layer 31 is arrayed inside the filter loading cylinder 5, and a hollow filter tube 32 is provided at the upper end of the filter loading cylinder 5. Figure 5 and Figure 6As shown, this structure allows the hydrolyzed flue gas to be adsorbed by the graphite filter layer 31 and the hollow filter tube 32, further increasing the cleanliness of the discharged flue gas.

[0043] Working principle: In use, connect the inlet pipe 2 to the outlet pipe. The flue gas enters the first loading box 1, which is between the movable plates 6. The flue gas is filtered by the filter layer 7, and after passing through multiple filter layers 7, it enters the connecting pipe 24 and is discharged to the lower side of the diverter plate 25. It then rises through the diverter hole 26, where the dust in the flue gas is hydrolyzed. The flue gas then enters the outlet pipe 4 and is filtered by the graphite filter layer 31 and the limiting roller 23 in the filter loading cylinder 5. To adjust the distance between the movable plates 6, hold the knob 12 and rotate it clockwise, causing the bidirectional screw 11 to rotate. The slider 8 moves closer together under the action of the threaded sleeve 10 and the bidirectional screw 11. The sealing block 20, engaged in the T-slot 14, also slides on the loading box cover 18. The filter layer 7 is folded into a V-shape. Because the filter layer 7 forms an angle when the movable plates 6 unfold, it can open and close smoothly. This reduces the space for flue gas diffusion, but the filtration area of ​​the filter layer 7 is reduced, making... When the filtration effect of the equipment is enhanced and the filter layer 7 needs to be cleaned, stretch the cloth strip 21 to disengage the iron ring 22 from the limiting roller 23, then open the loading box cover 18 and pull out the filter layer 7 for cleaning. When the filter loading cylinder 5 needs to be cleaned, unscrew the filter loading cylinder 5. At this time, the threaded ring 29 disengages from the second loading frame 3, and then the filter loading cylinder 5 can be cleaned. When changing the cleaning fluid in the second loading frame 3, open the threaded water plug 28 set at the water outlet to flush out the cleaning fluid, then seal the water outlet, and then open the threaded water plug 28 set on the water inlet pipe 27 to inject new cleaning fluid from the threaded water plug 28. The cleaning fluid fills the smoke outlet pipe 4 through the communicating vessel principle, and the injection is completed. Then, use the threaded water plug 28 to seal the water inlet pipe 27. The above is the complete working principle of the present invention.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
