The center plate 402 is arranged on the inner side of the outer ring 401 through a plurality of connecting rods 403. A rain cover 3 is arranged on the upper surface of the center plate 402 through a column. The rain cover 3 prevents rainwater from directly entering the chimney body 1. An annular pipe 9 is arranged on the lower surface of the center plate 402 through a hanging piece 8. A nozzle 10 is arranged on the lower panel of the annular pipe 9. The annular pipe 9 is connected to a connecting pipe 11. The connecting pipe 11 passes through the center plate 402 and is connected to a water inlet pipe 12. The water inlet pipe 12 is arranged along the outer edge of the chimney body 1. A plurality of pipe supports 14 are arranged on the outer wall of the chimney body 1. The water inlet pipe 12 is connected to the pipe support 14. The stability of the water inlet pipe 12 is ensured by the pipe support 14.

[0023] like Figure 5 As shown, the screen assembly 6 includes a ring body 601 and a screen 602. The screen 602 is arranged on the inner side of the ring body 601. The ring body 601 is connected to the upper surface of the annular support plate 5 by bolts. The outer diameter of the ring body 601 is smaller than the inner diameter of the top of the chimney body 1 to ensure that the screen assembly 6 can smoothly enter the chimney body 1.

[0024] Installation method and use principle: First, install the screen assembly 6 on the annular support plate 5 of the chimney body 1 through the ring body 601 and bolts, then install the annular pipe 9 on the lower surface of the center plate 402 of the support frame 4 through the hanger 8, and pass the connecting pipe 11 through the center plate 402, then install the support frame 4 on the top of the chimney body 1 through the outer ring 401 and bolts, and install the rain shield on the support frame 4 through the supporting column. Finally, connect the water inlet pipe 12 to the connecting pipe 11, and at the same time connect the water inlet pipe 12 to the pipe bracket 14 on the outer wall of the chimney body 1, so as to ensure the stability of the water inlet pipe 12. When in use, the air inlet interface 7 of the chimney body 1 is connected to the exhaust gas treatment device at the front end. When the exhaust gas completes the treatment port and enters the chimney, the residual particles in the exhaust gas are blocked by the screen 602 to prevent them from being discharged into the air. When a large amount of particulate dust adheres to the screen 602, water is supplied to the annular tube 9 through the water inlet pipe 12, and water is sprayed on the screen 602 through the nozzle 10 to rinse the adhered particulate dust and drip into the waste receiving trough 2 at the bottom, and finally discharged from the waste outlet 13. The utility model has reasonable results. The top of the chimney main body 1 is supported by a screen assembly 6 through an annular support plate 5. The particles in the treated exhaust gas can be blocked by the screen 602, thereby preventing the particles from being discharged into the air. At the same time, a support frame 4 is arranged on the top of the chimney main body 1. The lower surface of the central plate 402 of the support frame 4 is provided with an annular tube 9. The annular tube 9 is evenly provided with nozzles 10, and the annular tube 9 is connected to the water inlet pipe 12 through a connecting pipe 11. The screen 602 is flushed through the nozzle 10 without manual replacement or cleaning. The convenience and cleaning efficiency are greatly improved. A waste receiving trough 2 is arranged at the bottom of the chimney main body 1 to realize the discharge of particle dust.
