DETAILED DESCRIPTION

[0019] The specific embodiments of the present application will be further described in detail. Figures 1-5 The specific embodiments of the present application will be further described in detail.

[0020] In the use process, the dispersion motor 7 should be in the starting rotating state, thereby driving the dispersion blade 6 to rotate, and the rotation of the dispersion blade 6 can make the gas in the horizontal flue 1 flow from left to right. The flue gas to be desulfurized enters the horizontal flue 1 from the left end, and the desulfurization powder is released from the spherical nozzle 3 through the injection gun 2. The spherical nozzle 3 ensures the injection range of the desulfurization powder. The desulfurization powder ejected and the flue gas to be desulfurized are preliminarily mixed, and then flow to the right under the action of the dispersion blade 6. When passing through the dispersion blade 6, the flue gas to be desulfurized will also be stirred by the dispersion blade 6, further ensuring the mixing effect of the flue gas to be desulfurized and the desulfurization powder, ensuring that the two are mixed uniformly, and ensuring the desulfurization efficiency. The rapping drive device 17 can drive the rapping rod 11 through the armature plate 16, thereby making the rapping ball 12 knock the spherical nozzle 3, thereby vibrating the desulfurization powder attached to the spherical nozzle 3, thereby making the attached desulfurization powder fall off, avoiding the blockage of the spherical nozzle 3, and ensuring the normal release of the desulfurization powder.

[0021] In the use process, the dispersion motor 7 can drive the dispersion shaft 5 to rotate on the mounting frame 4, thereby making the dispersion blade 6 rotate. The dispersion blade 6 can guide the airflow in the horizontal flue 1 to move from left to right during the rotation process, and the rotating dispersion blade 6 can also stir the flue gas and the desulfurization powder in the horizontal flue 1, so that the two can be fully mixed, thereby ensuring the desulfurization efficiency.

[0022] Further, the front side of the horizontal flue 1 is also provided with a transparent tempered glass window 25, so that the staff can observe the rapping cleaning device and other components inside the horizontal flue 1 through the tempered glass window 25, thereby ensuring the normal operation of the present application.

[0023] Further, in order to avoid the blockage of the spherical nozzle 3 due to the adhesion of desulfurization powder, the shaking driving device 17 needs to be started regularly, so that the shaking cleaning device 8 can clean the spherical nozzle 3 regularly. Specifically, the step motor 22 of the shaking driving device 17 is started, the step motor 22 drives the reciprocating screw 18 to rotate, the reciprocating screw 18 drives the moving rod 20 to move reciprocally along the cross rod 19. During the reciprocating movement of the moving rod 20 along the cross rod 19, the displacement sensor 24 on the support rod 9 can monitor the position of the moving rod 20 in real time, as shown in the accompanying drawings Figure 2 When the moving rod 20 moves to the leftmost position, the spring 13 is in the maximum compression state, and the displacement sensor 24 monitors the position information of the moving rod 20 and transmits the information to the controller 23. The controller 23 controls the electromagnetic iron 21 to lose magnetism by being powered off, so that the armature plate 16 cannot be attracted by the electromagnetic iron 21. Under the self-lengthening action of the spring 13, the shaking rod 11 and the shaking ball 12 will move rightward along the sleeve 10 and hit the inlet end of the spherical nozzle 3, thereby causing the spherical nozzle 3 to vibrate and causing the adhesion of the desulfurization powder to fall off. The guide rod 15 cooperates with the guide groove 14 to limit the lateral movement of the guide sleeve along the sleeve 10.

[0024] Under the action of the displacement sensor 24 and the controller 23, the electromagnetic iron 21 will lose magnetism by being powered off when the moving rod 20 moves to the leftmost position, and the electromagnetic iron 21 will have magnetism by being powered on in other states. After the shaking ball 12 hits the spherical nozzle 3, the moving rod 20 will move rightward with the rotation of the reciprocating screw 18. When the moving rod 20 moves to the rightmost position, the electromagnetic iron 21 will attract the armature. With the continuous rotation of the reciprocating screw 18, the moving rod 20 will move leftward, and the electromagnetic iron 21 will also attract the armature plate 16 to move rightward. Then, the shaking rod 11 connected with the armature plate 16 through the guide rod 15 will also move rightward, and the spring 13 will be compressed. When the moving rod 20 moves to the leftmost position, the sensor will detect the position information and control the electromagnetic iron 21 to lose magnetism by being powered off again, and the above process is repeated.
