The working principle is as follows: firstly, catalyst is put into a regeneration device, a first motor 2 is started, the first motor 2 drives a first gear 3 to rotate, the first gear 3 drives a second gear 29 which is meshed with the first gear to rotate, the second gear 29 continuously drives a cam 30 which is fixed on the same shaft with the second gear to rotate, the side edge of the cam 30 is tightly attached to a roller 31, the roller 31 is fixed on an expansion link 33, and a second spring 32 is arranged between the roller 31 and a transverse plate of a support 34, so that when the cam 30 rotates, the roller 31 can be driven to reciprocate back and forth on the support 34, and meanwhile, the roller 31 can drive the expansion link 33 to reciprocate back and forth. Meanwhile, the other end of the telescopic rod 33 is connected to the first sliding plate 35, so that the first sliding plate 35 reciprocates back and forth along with the telescopic rod 33. Because the first sliding plate 35 can reciprocate back and forth when the denitration catalyst passes through the gas lance 6 and the spray pipe 14 below, can carry out more comprehensive dust removal and washing to the denitration catalyst, be favorable to improving the regeneration effect of denitration catalyst.

When the first motor 2 is started, the rotation of the second gear 29 drives the third gear 40 engaged with the third gear to rotate, the rotation of the third gear 40 drives the first bevel gear 41 fixed on the same shaft with the third gear to rotate, the first bevel gear 41 drives the second bevel gear 42 engaged with the first bevel gear to rotate, the second bevel gear 42 drives the second traction wheel 44 to rotate, one end of the traction rope 22 is connected to the second traction wheel 44, the traction rope 22 is wound on the first traction wheel 38, the other end of the traction rope 22 is connected to the sliding block 49, the first traction wheel 38 can change the direction of the traction rope 22, and therefore, when the second traction wheel 44 rotates, the sliding block 49 can be driven to move transversely on the first sliding plate 35. Can drive the denitration catalyst and loop through the left dust removal processing case of box 1 and the washing processing case in box 1 middle part when sliding block 49 transversely moves on first sliding plate 35, and finally reach in the right side dehydration processing case of box 1, when the denitration catalyst passes through the dust removal processing case, open air-blower 7 and air exhauster 11 simultaneously, air-blower 7 pours into air into jet-propelled pipe 6 into, the other end of jet-propelled pipe 6 carries out dust removal work with the air blowout to the denitration catalyst, air exhauster 11 takes the air that has dust impurity out the inside of box 1 through exhaust duct 9 simultaneously. When the denitration catalyst passes through the washing processing box, start solenoid valve 13, solenoid valve 13 passes through spray pipe 14 blowout with the inside water of water tank 12 to wash the denitration catalyst, the sewage accessible box 1 bottom after the washing leads the water course and flows into in the water storage box 17. When denitration catalyst reachs the dehydration process case, start dehydration motor 26, dehydration motor 26 drives fixed plate 24 rotatory, is connected with grip block 8 through electronic flexible post 47 on the fixed plate 24, and consequently the rotation of fixed plate 24 can drive the denitration catalyst of centre gripping on the grip block 8 and rotate, thereby accomplish the dehydration to denitration catalyst, the water that dehydration produced can flow into in the water drainage tank 21, open valve 20 back water can discharge inside the box 1. But set sliding block 49 into lateral shifting's form, help removing dust, washing and dehydration work to the denitration catalyst respectively, be favorable to improving denitration catalyst regeneration efficiency, reduction in production cost. Set up the dehydration processing case, help carrying out dehydration work to the denitration catalyst after wasing the processing, reduce the inside moisture of denitration catalyst so that carry out processing or transportation on its next step.

When the first motor 2 is started, the rotation of the first gear 3 can drive the transmission gear 4 meshed with the first gear to rotate, the transmission gear 4 can drive the first shaft 19 to rotate, the first shaft 19 drives the lifting gear 5 fixed on the first shaft to rotate, the lifting gear 5 drives the rack plate 18 meshed with the lifting gear to move downwards, the rack plate 18 is connected with the baffle 45, and therefore the baffle 45 can move downwards along with the rack plate 18, so that the denitration catalyst enters the cleaning processing box through the dedusting processing box. When the first motor 2 is rotated reversely, the damper 45 moves upward along with the rack plate 18, thereby separating the dust-removing processing box and the cleaning processing box. When removing dust to denitration catalyst and add man-hour, set up and reciprocate baffle 45 and can cut apart dust removal processing case and washing processing case, prevent that the dust that removes dust and produce from falling into washing processing incasement, pollute the internal environment who washs the processing case, after denitration catalyst dust removal processing accomplishes, reciprocate baffle 45 and move down and make things convenient for denitration catalyst to enter into and wash the processing incasement.

When denitration catalyst removes dust and adds man-hour, the air that contains dust and impurity that processing produced can enter into air exhaust duct 9 through air exhauster 11 in, and dust and impurity in the air can be adsorbed to the inside moist filter 10 that sets up of air exhaust duct 9, help air-purifying, prevent harmful gas pollution atmosphere harm user's healthy. When denitration catalyst washs the leading water tank 17 that the sewage that produces when adding man-hour can enter into box 16 through the leading water tank of box 1 bottom in, the filter screen 15 that sets up in the water tank 17 can filter sewage. Accomplish the dust removal when the denitration catalyst, after washing and the dehydration processing, pull down the apron 37 at 1 top of box earlier, adjust electronic flexible post 47 again and lift the denitration catalyst off and take out equipment, take out after the processing denitration catalyst again with unprocessed denitration catalyst put into the equipment in, control electronic flexible post 47 with the denitration catalyst fastening between two grip blocks 8, first motor 2 reverses, first spring 23 can drive in sliding block 49 gets back to the dust removal processing incasement, sliding block 49 drives unprocessed denitration catalyst and gets back to the initial position and process.
