the filter screen is characterized in that detachable side plates (5) are mounted on two sides of the frame (1), one end, opposite to each other, of each of the two side plates (5) is connected with a plurality of plugging plates (7), each plugging plate (7) is detachably mounted with the corresponding side plate (5), a clamping groove (6) is formed in the joint of each side plate (5) and each plugging plate (7), each plugging plate (7) is clamped inside the corresponding clamping groove (6), and each plugging plate (7) is abutted to the side faces of the filter screen (16) and the corresponding activated carbon layer (18);
the upper end and the lower end of the side plate (5) are both connected with end sealing plates (8), the end sealing plates (8) at the two ends are both hermetically connected with the upper end and the lower end of the frame (1), and the bottom of the side plate (5) at one side is provided with a pipeline connecting port;
a partition plate (10) is arranged at the bottom of the loading cavity (9), a plurality of through holes are formed in the partition plate (10), and the peripheral edges of the upper end and the lower end of the partition plate (10) are in sealing butt joint with the edge of the filter screen (16);
the specific steps used by the processing equipment include:
the method comprises the following steps: the flue gas treatment equipment is connected with a tail gas discharge pipeline of the kiln, and a discharge port of the tail gas discharge pipeline of the kiln is connected with a pipeline connecting port, so that flue gas discharged from the tail gas discharge pipeline enters the bottom of the purification mechanism (3) from the pipeline connecting port, and the flue gas can be continuously lifted upwards from the bottom of the purification mechanism (3); in the process that the smoke rises upwards from the bottom, impurities contained in the smoke are removed through the filtering adsorption of a plurality of filter screens (16) and a plurality of activated carbon layers (18); a flue gas pipeline is arranged at the top of the main body frame (1) through a support (2), so that the exhaust direction of flue gas is artificially changed according to the direction of the flue gas pipeline;
step two: after a plurality of internal purification units are used for a plurality of times, impurities are attached to the internal purification units; opening the fixed lock (20), pulling the handle (19) and pulling the purification unit out of the loading chamber (9); starting the first hydraulic column (15) to stretch and retract, driving the transverse plate (12) to move up and down until the scraper blade (21) and the cleaning plate (22) are in contact with the filter screen (16), scraping impurities attached to the outer part of the filter screen (16) by the scraper blade (21), and cleaning the filter screen (16) by the cleaning plate (22); after cleaning, the adsorption plate (23) adsorbs impurities, and the scraped impurities are absorbed into the conveying pipe (13) and then discharged from the conveying pipe (13) for storage, so that the impurities are prevented from remaining in the filter screen (16);
step three: when the purification unit is fully cleaned, the purification unit is taken out from the interior of the loading cavity (9), the filter screen (16) is detached, and the active carbon layer (18) in the purification unit is taken out for cleaning, so that the purification unit can be recycled, and the purification material in the purification unit does not need to be replaced;
step four: when the purification unit is installed, the filter screen (16) and the activated carbon layer (18) are assembled, and then the handle (19) is held to push the purification unit to the interior of the loading cavity (9); the two sides of the purification unit are clamped in the movable groove (27), and the purification unit continuously moves inwards along the movable groove (27) until the purification unit is arranged at a preset position; push plates (25) at the upper end and the lower end in the moving groove (27) are abutted against the edge of the purification unit under the driving of a second hydraulic column (24) to fix the purification unit;
hoisting rods (11) are welded on two sides of one end of the top of the main body frame (1), supports (2) are welded on two sides of the top, and a plurality of fixing holes are formed in the supports (2);
two one end both sides that diaphragm (12) kept away from mutually all install first hydraulic pressure post (15) with the inner wall of dismouting mouth (14) between, diaphragm (12) still install conveyer pipe (13) between two first hydraulic pressure posts (15), conveyer pipe (13) are connected with adsorption plate (23).
