[0002] Desulfurization and denitrification are one of the important technical measures for preventing and controlling air pollution. The high-temperature flue gas emissions generated in industrial production are the source of pollution caused by boiling medicine. A large amount of high-temperature flue gas will cause acid rain and photochemical smog, which will damage the environment and require a desulfurization and denitrification device for treatment. Publication number: CN 210522264U discloses a desulfurization and denitrification device, including a fuselage, an air inlet, an air outlet, a fan, a motor housing and a motor. The left side of the bottom end of the fuselage is provided with an air inlet, the right side of the top of the fuselage is provided with an air outlet, the bottom end of the fuselage is fixed with a fan, the left side of the fuselage is fixed with a motor housing by bolts, a motor is installed inside the motor housing, and the output end of the motor is connected with a first rotating shaft, the left end of the first rotating shaft is welded with a first gear, and the first gear is meshed with a second gear. The utility model drives the first rotating shaft to reverse the screw rod by reversing the motor, so that the storage chamber gradually moves upward, and the staff can remove the cover by turning the switch, which is convenient for replacing the catalyst and activated carbon fiber, improving the work efficiency, and does not require the staff to reach into the device for replacement, thereby improving the health and safety of the staff. However, the above technology does not have the function of removing dust from flue gas during use, resulting in poor desulfurization and denitrification effects and low purification rates due to dust and impurities in the flue gas during the desulfurization and denitrification process. At the same time, the dust contained in the purified gas will also cause certain pollution to the environment. Utility Model Content

[0028] Working principle: During use, start the No. 1 pump body 4 and the No. 2 pump body 9, and then the flue gas enters the interior of the ash filter housing 13 through the air intake pipe 5. The filter screen 20 inside the ash filter housing 13 performs the first filtration on the flue gas and filters out most of the dust in the flue gas. Then the flue gas enters the interior of the dust removal box 3 through the No. 1 duct 11. At this time, the water inside the dust removal box 3 enters the No. 2 pump body 9 from the connecting pipe 19. Under the action of the No. 2 pump body 9, the water is sprayed into the internal space of the dust removal box 3 along the water pipe 10 through the No. 2 atomizing nozzle 16. The dust will adhere to the water mist and fall into the filter box 17, thereby achieving preliminary filtration of the flue gas entering the dust removal box 3 through the filter screen 20, intercepting most of the dust in the flue gas, and setting the dust removal box 3 to perform secondary dust removal on the flue gas entering the dust removal box 3, and process the dust remaining in the flue gas, thereby improving the subsequent process of the flue gas entering the reaction box 2, and then the flue gas enters the interior of the reaction box 2 along the No. 2 conduit 12, and the desulfurization and denitrification reaction liquid in the liquid storage box 27 enters the liquid outlet pipe 14 along the liquid inlet pipe 8 through the No. 1 pump body 4, and the desulfurization and denitrification reaction liquid in the liquid outlet pipe 14 is sprayed on the interior of the reaction box 2 under the action of the No. 1 atomizing nozzle 15, and contacts and reacts with the flue gas, and the purified flue gas is discharged into the atmosphere along the exhaust pipe 7, and the desulfurization and denitrification reaction liquid sprayed and reacted in the reaction box 2 flows into the collecting box 6 through the guide hole 18. When a certain amount of desulfurization and denitrification reaction liquid accumulates in the collecting box 6, the handle on the collecting box 6 is pulled to slide the slider 24 on the collecting box 6 out of the inside of the slide groove 23, and then the discarded desulfurization and denitrification reaction liquid can be processed, thereby realizing the collection of the used desulfurization and denitrification reaction liquid, facilitating the centralized processing of the desulfurization and denitrification reaction liquid, and avoiding the desulfurization and denitrification reaction liquid from flowing into other places from the guide hole 18 to pollute the environment.
