Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] A desulfurized flue gas rectifying and demisting device disclosed in the present invention is mainly used in scenarios where the spraying equipment on the existing demisting device has limited cleaning effect on the fouling of the demisting blades.

[0027] Reference Figure 1-10A flue gas rectifying and demisting device for desulfurization includes a treatment tower 1, the bottom of the treatment tower 1 is connected to a base 2 by bolts, and a smoke exhaust pipe 3 is arranged on the upper side of the treatment tower 1, and a smoke conveying pipe 4 is arranged outside the treatment tower 1, and the inner wall of the treatment tower 1 is connected to two symmetrical square frame brackets 10 by bolts, and the same fixed-point high-pressure flushing module 7 is arranged above the two square frame brackets 10, and the fixed-point high-pressure flushing module 7 includes two symmetrical fixed plates 702, and a fixed plate 703 is arranged between the two fixed plates 702, and a plurality of connecting rods 704 are connected between the fixed plates 702 and the fixed plates 703 by bolts, and a plurality of equidistantly distributed placement grooves are opened on the fixed plates 702 and the fixed plates 703. , a diamond-shaped mesh sheet 705 is slidably connected in the placement groove, and the inner wall of the treatment tower 1 is connected to a ring gear 701 by bolts, the inner wall of the ring gear 701 is connected to a ring slide rail 706 by bolts, the outer side of the ring slide rail 706 is slidably connected to an arc-shaped sliding block 707, the side of the arc-shaped sliding block 707 away from the ring gear 701 is connected to a supporting plate 712 by bolts, a moving part 714 is arranged on the supporting plate 712, the inner wall of the moving part 714 is connected to a high-pressure nozzle 716 by bolts, the upper side of the high-pressure nozzle 716 is connected to a water injection pipe 717 by a flange, and two equidistantly distributed shaking modules 8 are arranged on the square frame bracket 10, and a fixed module 9 is arranged on the outside of the fixed plate 703.

[0028] Specifically, after the diamond-shaped mesh sheet 705 plugged on the fixing plate 1 702 and the fixing plate 2 703 is fixed by using the fixing module 9, the diamond-shaped mesh sheet 705, the fixing plate 1 702 and the fixing plate 2 703 are fixed as a whole on the frame bracket 10. After the flue gas transported into the treatment tower 1 through the smoke conveying pipe 4 is desulfurized, the desulfurized flue gas mixed with droplets flows upward and is intercepted by the diamond-shaped mesh sheet 705, so that the droplets adhere to the mesh on the diamond-shaped mesh sheet 705. After the droplets converge to a certain extent, the droplets will drip into the slurry pool at the bottom of the treatment tower 1 under the influence of gravity. In the process, when scaling occurs on the diamond hole mesh 705, the fixed-point high-pressure flushing module 7 can timely perform high-pressure flushing on the scaling part to remove the scaling.

The device utilizes the fixed-point high-pressure flushing module 7 to greatly improve the device's cleaning effect on the scaling on the diamond hole mesh 705, thereby avoiding the scaling on the diamond hole mesh 705 from being unable to be cleaned and causing the scaling to spread over a large area, thereby affecting the demisting effect of the device, thereby improving the demisting effect and use function of the device.

The end of the rotating rod 2 719 away from the connecting piece 721 is provided with a notch. A cylinder is rotatably connected to the notch through a bearing. The outside of the cylinder is rotatably connected to the rotating rod 1 718 through a bearing. A torsion spring 720 is wrapped around the outside of the cylinder. One end of the torsion spring 720 is connected to the outside of the rotating rod 2 719 through a bolt, and the other end is connected to the outside of the rotating rod 1 718 through a bolt. The end of the rotating rod 1 718 away from the torsion spring 720 is rotatably connected to the outside of the arc-shaped sliding block 707 through a bearing. The side of the moving block 707 away from the ring gear 701 is connected to a boss by bolts, and a thin rod is rotatably connected to the boss through a bearing. The outside of the thin rod is connected to a winding roller 725 by bolts, and the outside of the winding roller 725 is connected to a wire rope 723 by bolts. The end of the wire rope 723 away from the winding roller 725 is connected to the outside of the connecting piece 721 by bolts, and the outside of the boss is connected to a second motor 722 by bolts, and the output end of the second motor 722 is connected to one side of the thin rod through a coupling. A plurality of equidistantly distributed flow meters 724 are arranged at the bottom of the support plate 712.

[0030] Specifically, when the flue gas containing droplets flows upward from the bottom of the diamond-shaped mesh sheet 705, the fine droplets will be intercepted by the special diamond-shaped mesh on the diamond-shaped mesh sheet 705, and the small droplets will quickly gather on the diamond-shaped mesh sheet 705 to form large droplets that fall back to the bottom of the treatment tower 1, and the motor 1 710 is started, and the motor 1 710 drives the driving gear 711 to rotate, so that the driving gear 711 meshed with the ring gear 701 drives the arc-shaped sliding block 707 to slide in a circle on the annular slide rail 706, and the flow rate of the flue gas passing through the diamond-shaped mesh sheet 705 is detected by the flow meter 724 installed at the bottom of the support plate 712. When the flow meter 724 detects a position where the flow rate is lower than the normal value, the motor 1 710 will be turned off, and the arc-shaped sliding block 707 will no longer move, and the motor 2 722 will be started, and the motor 2 722 will drive the volume The wire roller 725 rotates, so that the winding roller 725 reels or releases the wire rope 723, so that the connecting piece 721 connected to the wire rope 723 drives the moving piece 714 connected to the connecting piece 721 to slide on the groove 713. When the wire rope 723 is reeled, the connecting piece 721 pushes the second rotating rod 719 to retract, so that the second rotating rod 719 and the first rotating rod 718 overcome the torsion force of the torsion spring 720 to fold. When the wire rope 723 is released, the torsion spring 720 drives the first rotating rod 718 and the second rotating rod 719 to gradually unfold from the folded state. After the moving piece 714 drives the high-pressure nozzle 716 to move to the abnormal flow rate position, the high-pressure pump 6 is started. The high-pressure pump 6 transports water to the high-pressure nozzle 716 through the water supply pipe 5 and the water injection pipe 717 and sprays it out at high pressure, thereby performing high-pressure washing on the structural parts that affect the flow rate.

[0031] In specific application scenarios, the fixed-point high-pressure flushing module 7 is mainly suitable for the fixed-point high-pressure flushing link in the fixed-point high-pressure flushing process, that is, the fixed-point high-pressure flushing module 7 uses the arc-shaped sliding block 707 that can rotate along the annular slide rail 706 to drive the support plate 712 to rotate, so that the flow meter 724 can detect the flue gas flow rate in a timely and full range, which greatly improves the detection speed and accuracy. By using the foldable rotating rod 1 718 and the rotating rod 2 719, the high-pressure nozzle 716 under the traction of the wire rope 723 can quickly position the structural parts, thereby improving the cleaning accuracy and cleaning effect of the device and ensuring the rectification and demisting efficiency of the device.

[0033] Specifically, when the plate-type demister formed by the diamond-shaped mesh sheet 705, the fixing plate 1 702 and the fixing plate 2 703 is fixed on the square frame bracket 10, the round rod 812 on the stable seat 811 connected to the fixing plate 1 702 is aligned with the connecting seat 804 and inserted, and the rotating frame 817 is rotated. The curved groove 818 on the rotating frame 817 pushes the short shaft 816 on the locking rod 815, so that the locking rod 815 can slide out of the connecting seat 804, so that the round rod 812 can be completely inserted into the connecting seat 804, and the rotating frame 817 is loosened. Under the torque of 819, the locking rod 815 is quickly reset and inserted into the annular groove 813 on the round rod 812, thereby completing the fixation of the round rod 812. When the fixed-point high-pressure flushing module 7 in the device flushes the scaling parts on the diamond hole mesh 705, the motor three 801 is started, and the motor three 801 drives the cam 802 to continuously collide with the push rod 807, and cooperates with the rebound of the spring one 809, so that the push rod 807 drives the connecting seat 804 and the diamond hole mesh 705 on the connecting seat 804 to shake regularly.

[0034] In specific application scenarios, the shaking module 8 is mainly suitable for the shaking link in the shaking process, that is, the shaking module 8 can use the locking rod 815 and the annular groove 813 to quickly and conveniently complete the fixation of the plate-type defogger formed by the diamond hole mesh 705 and the fixed plate 1 702 and the fixed plate 2 703, and with the help of the repetitive impact and rebound of the cam 802 and the spring 1 809, the diamond hole mesh 705 produces high-frequency shaking and vibration, thereby assisting the scale cleaning operation of the fixed-point high-pressure flushing module 7, so that the scale can fall off the diamond hole mesh 705 more quickly.

The locking hooks 904 on the two rectangular long rods 903 are staggered and symmetrical, and two symmetrical interlocking holes 905 are provided on the diamond-shaped hole mesh 705. The two interlocking holes 905 on the same diamond-shaped hole mesh 705 are located on both sides of the fixing plate 703, and the outer parts of the locking hooks 904 on the same side are plugged into the inner walls of the interlocking holes 905.

[0036] Specifically, after the diamond hole mesh 705 is inserted into the fixing plate 1 702 and the fixing plate 2 703, the torsion force of the coil spring 2 914 is overcome and the blocking rod 913 is rotated to disengage the blocking rod 913 from the clamping of the sear 915, and the elastic force of the spring 2 910 is overcome to push the locking ring 907 downward, so that the locking ring 907 slides downward on the guide buckle 908, so that the rack 909 on the locking ring 907 releases the lock on the outer gear ring 906, and the knob 911 is turned, and the knob 911 drives the screw The threaded rod 902 rotates, thereby rotating the threaded rod 902 toward the outside of the mounting plate 901. The threaded rod 902 moving outward drives the rectangular long rod 903 connected to it to move, so that the locking hook 904 at the bottom of the rectangular long rod 903 is inserted into the guide buckle 908 on the diamond hole mesh 705 during the movement. With the locking of the locking hooks 904 on the two rectangular long rods 903 in opposite directions and the cooperation of the fixing plate 1 702, the diamond hole mesh 705 is fixed on the fixing plate 2 703.

[0037] In specific application scenarios, the fixing module 9 is mainly suitable for the fixing link in the fixing process, that is, the fixing module 9 uses the locking hooks 904 installed in opposite directions on the two rectangular long rods 903 to enable the staggered moving rectangular long rods 903 to quickly lock the diamond hole mesh 705, thereby avoiding the diamond hole mesh 705 from slipping and falling off in the device. The double locking produced by the blocking rod 913 and the rack 909 ensures that the threaded rod 902 cannot rotate again, so that the locking hook 904 on the square long rod 903 and the mosaic hole 905 are always locked, thereby improving the fixing effect of the device on the diamond hole mesh 705, and also improving the convenience of disassembling and replacing the diamond hole mesh 705 after the diamond hole mesh 705 is damaged.

[0038] Working principle: After the diamond hole mesh 705 is inserted into the fixing plate 1 702 and the fixing plate 2 703, the torsion force of the coil spring 2 914 is overcome to rotate the blocking rod 913, so that the blocking rod 913 is disengaged from the clamping of the sear 915, and the elastic force of the spring 2 910 is overcome to push the locking ring 907 downward, so that the locking ring 907 slides downward on the guide buckle 908, so that the rack 909 on the locking ring 907 releases the lock of the outer gear ring 906, and the knob 911 is turned, and the knob 911 drives the threaded rod 902 to rotate, thereby rotating the threaded rod 902 toward the outside of the mounting plate 901, and the threaded rod 902 moving outward drives the threaded rod 902 with it The connected rectangular long rod 903 moves, so that the locking hook 904 at the bottom of the rectangular long rod 903 is inserted into the guide buckle 908 on the diamond hole mesh 705 during the movement. Under the locking of the locking hooks 904 on the two rectangular long rods 903 in opposite directions and the cooperation of the fixing plate 1 702, the diamond hole mesh 705 is fixed on the fixing plate 2 703. When the plate-type demister formed by the diamond hole mesh 705, the fixing plate 1 702 and the fixing plate 2 703 is fixed on the square frame bracket 10, the round rod 812 on the stable seat 811 connected to the fixing plate 1 702 is aligned with the connecting seat 804 and inserted, and the rotating frame 817 is rotated. The curved groove 818 on the rotating frame 817 pushes the short shaft 816 on the locking rod 815, so that the locking rod 815 can slide outward from the connecting seat 804, so that the round rod 812 can be fully inserted into the connecting seat 804, and the rotating frame 817 is loosened. Under the torsion of the coil spring 819, the locking rod 815 is quickly reset and inserted into the annular groove 813 on the round rod 812, thereby completing the fixation of the round rod 812. After the flue gas transported into the treatment tower 1 through the smoke conveying pipe 4 is desulfurized, the desulfurized flue gas is mixed with droplets and flows upward and is intercepted by the diamond-shaped mesh 705, so that the droplets adhere to the mesh on the diamond-shaped mesh 705. After the droplets gather to a certain extent, the droplets will drip into the slurry pool at the bottom of the treatment tower 1 under the influence of gravity, and the motor 1 710 is started. The motor 1 710 drives the driving gear 711 to rotate, so that the driving gear 711 meshed with the ring gear 701 drives the arc sliding block 707 to slide in a circle on the ring slide rail 706. The flow rate of the flue gas passing through the diamond hole mesh 705 is detected by the flow meter 724 installed at the bottom of the supporting plate 712. When the flow meter 724 detects that the flow rate is lower than the normal value, the motor 1 710 will be turned off, the arc sliding block 707 will no longer move, and the motor 2 722 will be started.The second motor 722 drives the winding roller 725 to rotate, so that the winding roller 725 reels or releases the wire rope 723, so that the connecting piece 721 connected to the wire rope 723 drives the moving piece 714 connected to the connecting piece 721 to slide on the groove 713. When the wire rope 723 is reeled, the connecting piece 721 pushes the second rotating rod 719 to retract, so that the second rotating rod 719 and the rotating rod 1 718 overcome the torsion force of the torsion spring 720 to fold. When the wire rope 723 is released, the torsion spring 720 drives the rotating rod 1 718 and the rotating rod 2 719 to gradually unfold from the folded state. After the moving part 714 drives the high-pressure nozzle 716 to move to the abnormal flow rate position, the high-pressure pump 6 is started, and the high-pressure pump 6 delivers water to the high-pressure nozzle 716 through the water delivery pipe 5 and the water injection pipe 717 and sprays it out at high pressure, thereby performing high-pressure washing on the structural parts that affect the flow rate, and the motor 3 801 is started. The motor 3 801 drives the cam 802 to continuously collide with the push rod 807, and the spring 1 809 rebounds, so that the push rod 807 drives the connecting seat 804 and the diamond-shaped hole mesh 705 on the connecting seat 804 to shake regularly, thereby accelerating the cleaning process.
