[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0017] See attached document Figure 1-4An integrated denitrification and dust removal device includes a tower body 1. A partition 2 is installed inside the tower body 1, dividing it into a denitrification and dust removal chamber 3 and a mixing and reaction chamber 4. The denitrification and dust removal chamber 3 contains a ceramic filter element structure 8. The mixing and reaction chamber 4 has a flue gas inlet 5 and a spray gun 7 installed on the tower body 1. The outlet of the mixing and reaction chamber 4 is located below the ceramic filter element structure 8. The denitrification and dust removal chamber 3 has a flue gas outlet 6 installed on the tower body 1, located above the ceramic filter element structure 8. A cooling device 9 is installed at the bottom of the tower body 1. This configuration integrates the denitrification and dust removal chamber 3 and the mixing reaction chamber 4 into a single unit, greatly reducing equipment costs and space requirements. During operation, flue gas is introduced through the flue gas inlet 5, and then ammonia is injected through the spray gun 7, allowing the mixing reaction to take place in the mixing reaction chamber 4. The flue gas after the mixing reaction flows downward through the mixing reaction chamber 4 and is filtered through the ceramic filter structure 8. Finally, the exhaust gas passes through the ceramic filter structure 8 and is discharged from the flue gas outlet 6. The silicon powder falls into the transmission pipe 10 and is cooled by the cooling device 9. Example

[0018] See attached document Figure 1 and 2 Based on Embodiment 1, a transmission pipe 10 is fixedly connected between the cooling device 9 and the tower body 1. A valve is installed on the transmission pipe 10. The cooling device 9 includes an inner cooling tower 91, within which a cooling pipe 93 is installed, penetrating the inner cooling tower 91. The cooling device 9 also includes a geared motor 92 that drives the cooling pipe 93. The cooling pipe 93 includes a first inlet 94 and a first outlet 95 located outside the inner cooling tower 91. A pulley assembly 15 is provided between the geared motor 92 and the cooling pipe 93. In this embodiment, the pulley assembly 15 is an active pulley mounted on the output end of the geared motor 92. The inner cooling tower 91 is connected to the inner cooling tower 91 via a discharge pipe 96, and an outer cooling tower 11 is provided outside the inner cooling tower 91. The outer cooling tower 11 includes a second water inlet 12 and a second water outlet 13. The discharge pipe 96 is connected to the outer cooling tower 11, and the discharge pipe 96 is equipped with a fan 14. Silicon powder is input into the cooling device 9 through the transmission pipe 10. Cooling water is input into the geared motor 92 through the first water inlet 94 and into the outer cooling tower 11 through the second water inlet 12, thereby cooling the silicon powder. After cooling, the silicon powder is discharged from the discharge pipe 96.
