[0025] When the staff processes the flue gas, the flue gas is transmitted to the cleaning box 13 through the discharge barrel 11, and then transmitted to the collection box 12. When processing different types of flue gas, the staff adjusts the number of cleaning boxes 13 so that the number of cleaning boxes 13 reaches the set number. The staff starts the lifting cylinder 62, and the lifting of the piston rod of the lifting cylinder 62 drives the lifting rod 63 to lift synchronously, thereby driving the lifting plate 61 and the ball to lift synchronously, so that the ball contacts the top of the frame 1, so that the staff can adjust the position of the cleaning box 13 conveniently.

[0026] A filter plate 71 is installed in each cleaning box 13. The horizontally arranged filter plate 71 is slidably connected to the inner side wall of the cleaning box 13. A transverse groove 14 is opened on the side wall of each cleaning box 13 for the filter plate 71 to pass through. The side wall of the horizontally arranged transverse groove 14 is slidably connected to the side wall of the filter plate 71. A cover plate 17 is installed on the side wall of the cleaning box 13. The vertically arranged cover plate 17 is detachably connected to the cleaning box 13 by bolts, and the cover plate 17 is used to cover the transverse groove 14.

[0027] A driving groove 15 is horizontally opened on the inner side wall of each cleaning box 13, and the side wall of the driving groove 15 is slidably connected to the side wall of the filter plate 71.

The side wall of the driving plate 72 abuts against the side wall of the filter plate 71. The driving member includes a rotating motor 81, a driving rod 75, a screw 7 4 and the screw sleeve 76, the rotary motor 81 is located on the side wall of the cleaning box 13 and is fixedly connected to the cleaning box 13, the output shaft of the rotary motor 81 is coaxially fixedly connected to the driving rod 75, one end of the horizontally arranged driving rod 75 passes through the side wall of the cleaning box 13 and is coaxially fixedly connected to the screw 74, the side wall of the driving rod 75 is rotatably connected to the side wall of the cleaning box 13, one end of the horizontally arranged screw 74 is penetrated through the driving plate 72 and the filter plate 71, and the screw 74 is rotatably connected to the driving plate 72 and the filter plate 71, the horizontally arranged screw sleeve 76 is sleeved on the screw 74 and is threadedly connected to the screw 74, and the end of the screw sleeve 76 abuts against the side wall of the driving plate 72.

[0028] The filter plate 71 filters the dirt in the cleaning box 13. When the dirt accumulates on the filter plate 71, the staff adjusts the cover plate 17 so that the cover plate 17 is separated from the transverse groove 14. At this time, the staff starts the rotating motor 81. The output shaft of the rotating motor 81 rotates to drive the driving rod 75 to rotate synchronously, thereby driving the screw rod 74 to rotate synchronously. The screw rod 74 rotates to drive the screw sleeve 76 to move along the axial direction of the driving rod 75, thereby driving the driving plate 72 to move synchronously, thereby driving the filter plate 71 to move in a direction away from the driving groove 15, thereby facilitating the separation of the filter plate 71 from the cleaning box 13. After the staff disassembles and replaces the filter plate 71, the staff transfers the new filter plate 71 to the cleaning box 13. Through the elastic potential energy of the cover plate 17 and the driving spring 73, the filter plate 71 is abutted and limited, thereby improving the stability of the filter plate 71 and thus improving the cleaning effect of the filter plate 71.

[0029] The working principle of the present invention is as follows: When the industrial coal-fired flue gas desulfurization equipment of this embodiment is in use, when the staff processes the flue gas, the staff transfers the flue gas to the discharge barrel 11, the cleaning box 13 and the collection box 12 in sequence, and cleans the flue gas through the liquid in the cleaning box 13. When the staff processes different types of flue gas, the staff adjusts the number of cleaning boxes 13, so that the number of cleaning boxes 13 reaches the set number, and the staff starts the lifting cylinder 62, and the lifting of the piston rod of the lifting cylinder 62 drives the lifting rod 63 to rise and fall synchronously, and then drives the lifting rod 63 and the lifting plate 61 to rise and fall synchronously, until the roller 18 at the bottom of the lifting plate 61 contacts the frame 1, so that the staff can adjust the position of the cleaning box 13 conveniently, so that the cleaning box 13 is transferred to the set position. The staff then starts the pushing cylinder 31, and the piston rod of the pushing cylinder 31 is extended and retracted to drive the pushing rod 32 and the pushing tube 23 to move synchronously until the end of the pushing tube 23 abuts against the baffle 33. At this time, the pushing tube 23 extends into the connecting tube 21, and driven by the elastic potential energy of the limit spring 53, the limit block 51 drives the limit rod 52 to rise and fall until the limit block 51 abuts against the limit groove on the pushing tube 23, thereby improving the stability of the pushing tube 23, making it difficult for the pushing tube 23 to separate from the connecting tube 21, thereby adapting to different types of industrial coal-fired flue gas, thereby eliminating the need to prepare multiple cleaning devices, saving production cleaning and processing costs, and improving resource utilization.
