Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0028] See also Figures 1 to 5 As shown, the present invention provides a technical solution, and the specific improvements are as follows:

[0029] A desulfurization, denitrification and dust removal device, comprising a bottom plate, a water tank 1 and a cooling cylinder 3 fixedly arranged on the top surface of the bottom plate through a support frame 2, the top of one side of the surface of the cooling cylinder 3 is connected with an exhaust pipe 15, a reaction cylinder 16 is fixedly arranged on one side of the top surface of the bottom plate, the bottom end of the exhaust pipe 15 is connected with the top end of the reaction cylinder 16, a sleeve 4 is fixedly arranged at the bottom of the inner wall of the cooling cylinder 3, a cooling mechanism 5 is arranged inside the cooling cylinder 3, and the cooling mechanism 5 includes a cooling pipe 51 arranged inside the sleeve 4, and the cooling A heat conducting pipe 52 is fixedly arranged inside the pipe 51, and the top end of the heat conducting pipe 52 passes through the cooling pipe 51 and extends to the top end of the cooling pipe 51. One side of the top surface of the cooling pipe 51 is connected to one side of the water tank 1 through the second water inlet pipe 7. A second solenoid valve is arranged inside the second water inlet pipe 7. A plurality of inclined plates 53 are arranged on the inner wall of the heat conducting pipe 52. The arrangement of the inclined plates 53 can reduce the circulation of the flue gas and increase the contact time between the high-temperature flue gas and the cold source. The inner wall of the cooling pipe 51 and the surface of the heat conducting pipe 52 are fixedly arranged. A spiral guide plate 54 is arranged, which can slow down the circulation speed of cooling water and improve the cooling efficiency of flue gas. The surface of the sleeve 4 is provided with a plurality of through holes 55. The top surface of the sleeve 4 is rotatably provided with an annular plate 56. The top surface of the annular plate 56 is fixed with a rotating ring 9 through a vertical rod. A first motor 10 is fixedly arranged on one side of the top surface of the support frame 2, and a gear 11 is fixedly arranged on one end of the output shaft of the first motor 10 through a coupling. The surface of the gear 11 is connected to the rotating ring 9 through teeth. The surfaces of the rings 9 mesh with each other, a dispersion member is provided at the bottom of the annular plate 56, and the dispersion member includes a rotating rod 59 fixedly provided on both sides of the bottom of the annular plate 56, and a dispersion plate 510 is provided on both sides of the surface of the rotating rod 59, and a water separation plate 57 is provided on the inner wall of the cooling cylinder 3 and on the surface of the annular plate 56, and a spray nozzle 58 is fixedly provided at the bottom of the water separation plate 57, and one side of the top surface of the water separation plate 57 is connected to the bottom surface of the water tank 1 through the first water inlet pipe 6, and a first solenoid valve is provided inside the first water inlet pipe 6;

[0030] After dust removal, the flue gas enters the interior of the heat-conducting pipe 52 through the exhaust pipe 18. The second solenoid valve is opened in advance, so that the cooling water stored in the water tank 1 is transported to the interior of the cooling pipe 51 through the second water inlet pipe 7. The circulation speed of the cooling water is reduced by the spiral guide plate 54, and the high-temperature flue gas inside the heat-conducting pipe 52 is cooled by the cooling water. When the cooling water flows to the bottom of the cooling pipe 51, the cooling water after absorbing heat is discharged and collected for subsequent use. By controlling the cooling water to continuously enter the interior of the cooling pipe 51, the continuous cooling of the flue gas is achieved. At the same time, the flue gas flows from the top of the heat-conducting pipe 52 to the interior of the sleeve 4, and then discharged from a plurality of through holes 55 on the surface of the sleeve 4, so that the flue gas can be diverted;

[0031] At the same time, the first motor 10 is started and the first solenoid valve is opened, and the cooling water inside the water tank 1 is transported to the inside of the water distribution plate 57 through the first water inlet pipe 6, and finally sprayed into the flue gas by the spray nozzle 58 in atomization. The first motor 10 drives the rotating ring 9 to rotate through the gear 11 and the teeth, and the rotating ring 9 drives the annular plate 56 to rotate synchronously. At this time, the circulation of the flue gas can be accelerated through the dispersion member, so that the spray water is in full contact with the flue gas, and the cooling effect of the flue gas is further improved. The spray water cools the flue gas to 65-70°C, and finally the flue gas enters the inside of the reaction tube 16 through the exhaust pipe 15, and flue gas desulfurization and denitrification are achieved by electron beam radiation.

[0034] The excess spray water inside the cooling tube 3 enters the recovery tube 12 through the first water outlet pipe 13, and the water inside the cooling tube 51 after the heat is absorbed by the high-temperature flue gas is collected into the recovery tube 12 through the second water outlet pipe 14. The water collected inside the recovery tube 12 can be used in other places, saving a lot of water resources. Embodiment 3

[0037] Remove the cover plate upwards so that the pressure rod releases the pressure on the support plate 19. Subsequent personnel only need to take the support plate 19 to remove the internal filter cartridge 20, and remove the filter cartridge 20 from the inside of the support plate 19 for replacement;

[0038] During cleaning, the second motor 83 is started so that the second motor 83 drives the transmission gear 84 to rotate. When the transmission gear 84 rotates, it can move downward along the toothed plate 82 while rotating. Since one end of the output shaft of the second motor 83 is rotatably arranged with the surface of the fixed rod, it can drive the annular cleaning brush 81 to move downward along the surface of the filter cartridge 20, thereby cleaning impurities on the surface of the filter cartridge 20.

[0041] When cleaning impurities on the surface of the filter cartridge 20, the third motor 21 is started, so that the third motor 21 drives the sealing plate 23 to rotate, and the sealing plate 23 is rotated to Figure 6 State, so that the top of the collection box 22 is open, so that impurities can fall into the interior of the collection box 22 and complete the collection. On the contrary, when the smoke is filtered normally, the sealing plate 23 is controlled to close the top surface of the collection box 22 to prevent the smoke from blowing up the impurities inside the collection box 22 and affecting the normal filtering of the smoke.
