5. The dust removal and sulfur removal environmental protection equipment for industrial boiler flue gas treatment according to claim 4 is characterized in that: The bottoms of the plurality of connecting rods (6) are fixedly connected to the same horizontal plate (12), the bottom of the horizontal plate (12) is fixedly connected to a vertical plate (29), one side of the vertical plate (29) is fixedly connected to two symmetrically arranged clamping blocks (28), and one side of the baffle plate (13) is provided with a clamping groove (27) that is engaged with the clamping block (28).

6. The dust removal and sulfur removal environmental protection equipment for industrial boiler flue gas treatment according to claim 5 is characterized in that: The top of the piston plate (33) is fixedly connected to a first rack (25); the inner wall of the box body (1) is provided with two symmetrically arranged rotating shafts (15); the outer wall fixed sleeve of the rotating shaft (15) is provided with a spur gear (26) meshing with the first rack (25); and the outer wall fixed sleeve of the rotating shaft (15) is provided with a plurality of fan blades (16).

7. The method for using the dust removal and sulfur removal environmental protection equipment for industrial boiler flue gas treatment according to claim 6 is characterized in that: The specific steps include: S1. When in use, the flue gas is fed into the interior of the box (1) through the liquid inlet pipe (2), and first enters the desulfurizing agent remaining at the bottom of the box (1) to perform initial desulfurization. After the liquid surface is discharged, the atomizing nozzle (11) feeds the desulfurizing agent through the external liquid supply device to perform a second desulfurization on the gas, and the desulfurizing agent remains at the bottom of the box (1) to facilitate subsequent use of the flue gas; S2, the smoke enters the interior of the filter box (8) through the exhaust port (18), is filtered by a plurality of filter screens (20), and is finally discharged from the exhaust pipe (9), and the impurities remain on the collection box (7). Subsequently, the collection box (7) is slid horizontally, and the collection box (7) drives the slide block (23) to slide out in the slide groove (24). At the same time, the connecting rod (6) drives the horizontal plate (12) to move horizontally, and the horizontal plate (12) drives the vertical plate (29) and the clamping block (28) to move horizontally. At this time, the clamping block (28) is no longer engaged with the clamping groove (27), and the impurities are discharged; S3, starting the servo motor (37), the output shaft of the servo motor (37) drives the half gear (30) to rotate, the half gear (30) drives the second rack (31) to move vertically downward, the second rack (31) drives the bottom plate (3) to move vertically downward, the bottom plate (3) drives the baffle plate (13) and the round rod (34) to move vertically downward, at this time the baffle plate (13) no longer blocks the second liquid outlet (36), at the same time the round rod (34) drives the piston plate (33) to move vertically downward and enter the interior of the drainage box (5), at this time the desulfurizer in the drainage box (5) is discharged through the second liquid outlet (36); S4. When the second rack (31) and the half gear (30) are no longer meshed, the bottom plate (3) rebounds vertically upward under the tension of the tension spring (32). At this time, the piston plate (33) moves out of the interior of the drainage box (5), and the desulfurizer enters the interior of the drainage box (5). This reciprocating movement discharges a portion of the desulfurizer. At the same time, the piston plate (33) drives the first rack (25) to move vertically upward, the first rack (25) drives the spur gear (26) to rotate, and the spur gear (26) drives the rotating shaft (15) and the fan blade (16) to rotate, thereby generating airflow, extending the reaction time of the gas, and achieving a better effect. S5. When the bottom plate (3) moves upward, it drives the horizontal plate (12) to move vertically upward. The horizontal plate (12) drives the plurality of connecting rods (6) to move vertically upward. The connecting rods (6) drive the mounting plate (19) to move vertically upward. The mounting plate (19) drives the brush (21) to move vertically upward. The brush (21) cleans the filter (20), thereby extending the service life of the filter (20). At the same time, the filter (20) can be taken out from the top, which is convenient for replacement and use.
