PROBLEM TO BE SOLVED: To provide a dust removal device which may collect dust in air at a high collection rate, achieves low equipment costs, and makes labor for maintenance small.SOLUTION: A duct removal device 1 includes: a casing 10; a first nozzle 20; and a second nozzle 30. The casing 10 is erected in a vertical direction and a first opening 11 and a second opening 12 are formed. The first and second nozzles 20, 30 are disposed in the casing 10 and jet a misty solution downward. The first opening 11 is formed above the first and second nozzles 20, 30. The second opening 12 is formed below the first and second nozzles 20, 30. The first nozzle 20 is disposed below the second nozzle 30. A particle diameter of the solution jetted from the first nozzle 20 is larger than a particle diameter of the solution jetted from the second nozzle 30. |
