[0035] The flue gas treatment device also includes a deacidification tower 4, an emission tower 9 and a deacidification agent bin 11. The deacidification tower 4 and the emission tower 9 are arranged outside the box body 1. An exhaust pipe 16 is provided on the top of the box body 1. The end of the exhaust pipe 16 away from the box body 1 is connected to the emission tower 9. The top of the deacidification tower 4 is provided with a smoke conveying pipe 6 and a smoke guide pipe 15. The end of the smoke guide pipe 15 away from the deacidification tower 4 is connected to the side of the box body 1 close to the deacidification tower 4 and is connected to the box body 1. A fan 5 is provided at the bottom of the deacidification tower 4.
[0036] A stand 10 is provided on the outside of the deacidification tower 4, and a deacidification agent bin 11 is provided on the stand 10. A guide pipe 12 is provided at the bottom of the deacidification agent bin 11, and one end of the guide pipe 12 away from the deacidification agent bin 11 is connected to the deacidification tower 4; a pump 2 13 is provided below the deacidification agent bin 11, and the output end of the pump 2 13 is connected to the guide pipe 12 through a conduit.

[0038] The flue gas from the steel mill enters the deacidification tower 4 through the smoke conveying pipe 6. The pump 2 13 conveys the deacidification agent in the deacidification agent bin 11 to the deacidification tower 4 through the guide pipe 12, thereby converting the sulfide in the flue gas into flocs, and then conveying it into the box 1 through the smoke guide pipe 15. When the flue gas enters the box 1, the flue gas is filtered by the ceramic fiber filter plate 2. The ceramic fiber filter plate 2 filters the dust and flocs in the flue gas. The catalyst in the ceramic fiber filter plate 2 catalytically treats the nitrogen oxides in the flue gas. The treated flue gas is conveyed to the discharge tower 9 through the exhaust pipe 16 for discharge.
[0039] The ceramic fiber filter plate 2 may become clogged after long-term use and the catalyst on the ceramic fiber filter plate 2 will gradually become inactivated. At this time, the vibration enhancement module 8 is first used to drive the mounting plate 701 to vibrate, thereby driving the ceramic fiber filter plate 2 to vibrate. The dust and flocs on the ceramic fiber filter plate 2 can fall into the dust hopper 14 and are eventually collected by the dust box 3, thereby reducing the blockage of the ceramic fiber filter plate 2; then the replenishing mechanism is moved and the catalyst is replenished to the ceramic fiber filter plate 2 during the movement, so that the entire plate surface of the ceramic fiber filter plate 2 can be soaked with the catalyst, so that the catalyst remains in a sufficient state, thereby effectively ensuring the catalytic treatment effect on nitrogen oxides.
[0040] In this embodiment, the supplementary mechanism includes a movable platform 1 705, a movable platform 2 706 and a movable platform 713. The movable platform 1 705 and the movable platform 2 706 are symmetrically arranged above the fixed plate 702.

The two guide rods 712 are symmetrically arranged on both sides of the threaded rod 711. Two symmetrical through holes are opened on the movable platform 713, and the two guide rods 712 are slidably connected to the two through holes respectively.
[0042] Two parallel guide rods 704 are provided on the fixed plate 702, and the movable platform 1 705 and the movable platform 2 706 are slidably connected to the two guide rods 704 respectively; four mounting seats 703 are provided on the top of the fixed plate 702, and a single guide rod 704 is connected between two of the mounting seats 703.
[0043] A rack 707 is provided on one of the guide rods 704, and an opening is provided on the movable platform 2 706 along the length direction of the guide rod 704, for the rack 707 to pass through the opening; a narrow slot 708 is provided on the top of the movable platform 2 706, and the narrow slot 708 is connected to the opening, and a motor 2 710 is provided on the top of the movable platform 2 706, and the output end of the motor 2 710 is coaxially connected to the gear 3 709 through a coupling, and the gear 3 709 extends into the narrow slot 708 and engages with the rack 707.
[0044] A storage cylinder 719 is located on top of the mobile platform 713. A liquid infusion tube 720 is installed on top of the storage cylinder 719. The end of the liquid infusion tube 720, away from the storage cylinder 719, is connected to the nozzle 718. A pump 721 is located at the bottom of the mobile platform 713. The output end of the pump 721 is connected to the liquid infusion tube 720 via a conduit. The smoke guide 15 is connected to the housing 1 at one end, below the ceramic fiber filter plate 2. The center of the fixed plate 702 is hollowed out to allow filtered smoke to pass through. The ceramic fiber filter plate 2 and the mounting plate 701 can be integrated.
[0045] After the flue gas is transported to the box body 1 through the smoke guide pipe 15, the flue gas passes upward through the ceramic fiber filter plate 2, which filters out dust and flocs in the flue gas. The catalyst impregnated in the ceramic fiber filter plate 2 catalyzes the nitrogen oxides passing through the ceramic fiber filter plate 2 and converts them into nitrogen and water. During long-term use, the catalyst gradually deactivates, causing the nitrogen oxides passing through the ceramic fiber filter plate 2 to increase. At this time, the motor 2 710 is started, and the motor 2 710 drives the gear 3 709 engaged with the rack 707 to rotate, so that the movable platform 1 705, the movable platform 2 706 and the movable platform 713 slide along the length direction of the guide rod 704. At the same time, the motor 1 716 is started, and the motor 1 716 drives the gear 3 709 engaged with the rack 707 to rotate, thereby causing the movable platform 1 705, the movable platform 2 706 and the movable platform 713 to slide along the length direction of the guide rod 704. Gear 1 714 meshed with gear 2 715 rotates, thereby causing gear 1 714 to drive threaded rod 711 to rotate. Under the guidance of guide rod 712, movable platform 713 moves on threaded rod 711. Driven by movable platform 713, detector 717 at the bottom of movable platform 713 moves over the entire range above the entire ceramic fiber filter plate 2, thereby detecting the position where the nitrogen oxide concentration on the ceramic fiber filter plate 2 exceeds the standard. After detecting the position where the concentration exceeds the standard, pump 1 721 is started. Pump 1 721 draws out the catalyst in storage cylinder 719 and delivers it to nozzle 718 through infusion tube 720 for spraying, thereby spraying and replenishing the position of ceramic fiber filter plate 2 where the catalyst is insufficient.
[0046] See also Figure 6 、 Figure 7 In this embodiment, the vibration enhancement module 8 includes an insertion rod 803 and a stabilizing seat 817. The insertion rod 803 slides through the fixed plate 702 and is connected to the stabilizing seat 817. The stabilizing seat 817 is connected to the mounting plate 701. A limiting ring 804 is provided on the insertion rod 803. A spring 805 is fixed to the bottom of the limiting ring 804. The end of the spring 805 away from the limiting ring 804 is fixedly connected to the fixed plate 702; a connecting rod 806 is provided on the insertion rod 803, and an L-shaped plate 807 is fixedly connected to the bottom of the connecting rod 806. The L-shaped plate 807 is spaced apart from the fixed plate 702; the vibration enhancement module 8 also includes a knocking mechanism for knocking the L-shaped plate 807, and the knocking mechanism is provided on the fixed plate 702.
[0047] There are two vibration enhancement modules 8, and the two vibration enhancement modules 8 are symmetrically arranged along the length direction of the guide rod 704. Each vibration enhancement module 8 includes two insertion rods 803 and two stabilizing seats 817. Four circular openings are opened on the fixing plate 702, and the four insertion rods 803 are respectively slid through the four circular openings. The bottom of each stabilizing seat 817 is connected to the top of the mounting plate 701 by bolts.

[0049] Each insertion rod 803 is provided with a limiting ring 804, and each limiting ring 804 is located above the fixed plate 702. The tops of the two insertion rods 803 on the same side are connected to a connecting rod 806, and the bottoms of the two connecting rods 806 are connected to an L-shaped plate 807; each knocking mechanism includes two connecting frames 808, and two round rods 809 are connected between the two connecting frames 808, and the two connecting frames 808 are provided with circular grooves, and a round shaft 811 is rotatably connected in the circular groove through a bearing, and the round shaft 811 is coaxially connected to the winding roller 810; the wire rope 812 is simultaneously wrapped around the two round rods 809, one end of the wire rope 812 is connected to the winding roller 810, and the other end is connected to a hanging hammer 813, and the hanging hammer 813 is located above the L-shaped plate 807; two motors 814 are provided on the fixed plate 702, and the two motors 814 correspond to the two knocking mechanisms respectively to drive the corresponding winding roller 810 to rotate.
[0050] When the dust and flocs filtered out of the ceramic fiber filter plate 2 accumulate at the bottom of the ceramic fiber filter plate 2, the motor 3 814 is started. The motor 3 814 drives the winding roller 810 to rotate through the transmission roller 815 and the belt 816, so that the winding roller 810 reels the wire rope 812. After the reeled wire rope 812 drives the hanging hammer 813 to rise to a height, the motor 3 814 is turned off. The hanging hammer 813 falls rapidly under the action of gravity, thereby impacting the L-shaped plate 807. The impacted L-shaped plate 807 drives the insertion rod 803, the limiting ring 804, the stabilizing seat 817 and the mounting plate 701 through the connecting rod 806 to overcome the elastic force of the spring 805, so that the ceramic fiber filter plate 2 on the mounting plate 701 vibrates, thereby vibrating the dust and flocs on the ceramic fiber filter plate 2 off.
[0051] The top of each stabilizing seat 817 is provided with a plurality of circumferentially equidistant grooves 818, and a locking block 819 is slidably arranged in each groove 818. The outside of the insertion rod 803 is provided with an annular groove 802 for the locking block 819 to be engaged, and the top of each locking block 819 is provided with a short shaft 820; the top of each stabilizing seat 817 is rotatably connected to a rotating frame 801, and each rotating frame 801 is provided with a plurality of circumferentially equidistantly distributed curved grooves 821, and the plurality of short shafts 820 extend into the plurality of curved grooves 821 one by one and cooperate with the curved grooves 821, and each rotating frame 801 is provided with a coil spring 822, and the end of the coil spring 822 away from the rotating frame 801 is fixedly connected to the top of the corresponding stabilizing seat 817.
[0052] The curved groove 821 is an arc-shaped groove. The number of the cutting groove 818 and the curved groove 821 can be selected to be three. Correspondingly, the number of the locking blocks 819 is also three. The short shafts 820 on the three locking blocks 819 correspond one-to-one with the three curved grooves 821.
[0053] When the ceramic fiber filter plate 2 needs to be replaced, the rotating frame 801 is rotated to overcome the torsion of the coil spring 822, so that the curved groove 821 on the rotating frame 801 pushes the short shaft 820 connected to the locking block 819, causing the locking block 819 to slide outward in the cutting groove 818, thereby releasing the locking block 819 from the annular groove 802 on the insertion rod 803, and the insertion rod 803 can be disengaged from the stabilizing seat 817, thereby facilitating the removal of the mounting plate 701.
[0054] In specific application scenarios, the vibration enhancement module 8 can set the frequency of knocking according to the usage time of the ceramic fiber filter plate 2. In addition, the vibration intensity of the ceramic fiber filter plate 2 can be set by adjusting the height of the pendulum 813, thereby ensuring the device's treatment effect on dust and flocs.
[0055] The working principle of the flue gas treatment device is as follows: the flue gas from the steel mill enters the deacidification tower 4 through the smoke conveying pipe 6, and the pump 2 13 conveys the deacidification agent in the deacidification agent bin 11 to the deacidification tower 4 through the guide pipe 12, converts the sulfide in the flue gas into flocs, and then conveys it into the box 1 through the smoke guide pipe 15. After the flue gas enters the housing 1, it is filtered by the ceramic fiber filter plate 2. The ceramic fiber filter plate 2 filters the dust and flocs in the flue gas, and the catalyst in the ceramic fiber filter plate 2 catalytically treats the nitrogen oxides in the flue gas. After long-term use, the ceramic fiber filter plate 2 may become clogged and the catalyst on the ceramic fiber filter plate 2 will gradually become inactivated. At this time, the vibration enhancement module 8 is first used to drive the mounting plate 701 to vibrate, thereby driving the ceramic fiber filter plate 2 to vibrate. The dust and flocs on the ceramic fiber filter plate 2 can fall into the dust hopper 14 and are finally collected by the dust box 3, thereby reducing the blockage of the ceramic fiber filter plate 2; then the movable platform 713 is driven to move and the detector 717 is used to monitor the flue gas composition passing through the ceramic fiber filter plate 2 during the movement of the movable platform 713. At the same time, the inactivated catalyst is replenished by the nozzle 718 so that the entire plate surface of the ceramic fiber filter plate 2 can be soaked with the catalyst, so that the catalyst remains in a sufficient state, thereby effectively ensuring the catalytic treatment effect on nitrogen oxides.
[0056] To sum up, the embodiment of the present application provides a flue gas treatment device, including a box body 1, a positioning and replenishing module 7 and a vibration enhancement module 8. When the catalyst needs to be replenished, the vibration enhancement module 8 is first used to drive the mounting plate 701 to vibrate, thereby driving the ceramic fiber filter plate 2 to vibrate. The dust and flocs on the ceramic fiber filter plate 2 can fall into the dust hopper 14 and are eventually collected by the dust box 3, thereby reducing the blockage of the ceramic fiber filter plate 2; then the movable platform 713 in the positioning and replenishing module 7 is moved, and during the movement of the movable platform 713, the catalyst is replenished to the ceramic fiber filter plate 2 through the nozzle 718, so that the entire plate surface of the ceramic fiber filter plate 2 can be soaked with the catalyst, so that the catalyst remains in a sufficient state, thereby effectively ensuring the catalytic treatment effect on nitrogen oxides.
