The end face of the diverter block 5 is fixedly connected with the first tube body 9, and the first tube body 9 rotates through the reaction box body 1. The outer surface of the other side of the reaction box body 1 is fixedly connected with a second fixing frame 14, and the inner surface of the second fixing frame 14 is fixedly connected with a fixing joint 15. The inner surface of the fixing joint 15 is rotatably connected to the outer surface of the first tube body 9, and the top of the reaction box body 1 is fixedly connected with a box cover 2, and the bottom of the reaction box body 1 is fixedly connected with a discharge pipe 13. The outer surface of one side of the reaction box body 1 near the bottom is fixedly connected with an air inlet pipe 11, and the outer surface of the other side of the reaction box body 1 near the top is fixedly connected with an exhaust pipe 10.

[0025] The effect achieved by the entire embodiment 1 is that, during the desulfurization and denitrification treatment of the exhaust gas in a thermal power plant, when the box cover 2 is sealed and the discharge pipe 13 is closed, after the exhaust gas enters the reaction box 1 from the air inlet pipe 11, the external conveying device conveys the desulfurization and denitrification mixture through the fixed joint 15 and the first pipe body 9 to the diverter block 5, and the mixed treatment agent will be sprayed into the reaction box 1 from multiple atomizing nozzles 6, and the motor 3 is started synchronously.

When cleaning accumulated dust, the mounting plate 704 utilizes the rebound force of multiple springs 706 to make the multiple bristles 705 closely contact the surface of the diverter block 5 and multiple atomizing nozzles 6, and when the diverter block 5 rotates, the mounting plate 704 adaptively slides between the inner walls of the connecting plate 703 through multiple guide rods 707, thereby playing a guiding role, preventing the mounting plate 704 from swinging up and down when the diverter block 5 rotates for cleaning, and has high practicality.

[0028] Working principle: During the desulfurization and denitrification treatment of waste gas in a thermal power plant, when the box cover 2 is sealed and the discharge pipe 13 is closed, the waste gas enters the reaction box 1 from the air inlet pipe 11, and the external conveying device conveys the desulfurization and denitrification mixture through the fixed joint 15 and the first pipe body 9 to the diverter block 5. The mixed treatment agent will be sprayed into the reaction box 1 from multiple atomizing nozzles 6, and the motor 3 will be started synchronously. The output end of the motor 3 drives the rotating rod 4 to rotate inside the reaction box 1, which can drive the diverter block 5 to rotate inside the reaction box 1. Spray the mixed treatment agent to make the atomized mixed treatment agent evenly distributed in the reaction box 1 to react with the oxides and sulfur oxides in the exhaust gas, and condense and aggregate with the smoke particles in the exhaust gas and then settle downward to fall into the bottom of the reaction box 1. After the reaction is completed, open the valve on the surface of the discharge pipe 13 to discharge the waste gas after desulfurization and denitrification treatment. The waste gas is discharged from the exhaust pipe 10. When it is necessary to clean the smoke particles attached to the surface of the diverter block 5, start the electric telescopic rod 702, and its telescopic end extends to push down the connecting plate 70 3. Drive the mounting plate 704 out of the mounting shell 701 until the multiple bristles 705 arranged on its surface contact the surface of the diverter block 5, and cooperate with the starting motor 3 to drive the surface of the diverter block 5 to rub and clean with the multiple fitted bristles 705, and clean the smoke and dust particles accumulated on the surfaces of the diverter block 5 and the atomizing nozzle 6, avoiding the need for personnel to disassemble the equipment for cleaning. By fixing the first fixing frame 8 on one side of the inner surface of the reaction box 1, the diverter block 5 rotates synchronously with the inner surface of the first fixing frame 8 when driving the first tube body 9 and the fixed joint 15 to rotate, playing a supporting role. When cleaning the accumulated dust, the mounting plate 704 uses the rebound force of multiple springs 706 to make the multiple bristles 705 closely contact the surfaces of the diverter block 5 and the multiple atomizing nozzles 6, and when the diverter block 5 rotates, the mounting plate 704 adaptively slides between the inner walls of the connecting plate 703 through multiple guide rods 707, playing a guiding role, preventing the mounting plate 704 from swinging up and down when the diverter block 5 rotates for cleaning, and has high practicality.
