Abstract:
1. A dust removing and cooling apparatus comprising: a body comprising a first storage space in which water is stored and a second storage space in which a lower portion of the body communicates with the first storage space, wherein an inlet that communicates with the first storage space and an outlet that communicates with the second storage space are formed in an upper portion of the body; a water tank disposed in the first storage space and below the inlet; a first water flow sheet which is disposed below the water tank and has a tapered shape that becomes gradually narrower towards a lower portion of the first water flow sheet, and in which a first discharge hole is formed on a lower end of the first water flow sheet; a mixture tube disposed below the first discharge hole; a dust collecting and cooling portion which is disposed below the mixture tube, has a tapered shape that becomes gradually narrower towards a lower portion of the dust collecting and cooling portion and comprises a second water flow sheet in which a second discharge hole is formed on a lower end of the second water flow sheet; a gas inflow portion connected to the inlet and allowing contaminated harmful gases to be flowed into the first storage space; a water circulation portion having one end connected to an upper portion of the body and the other end connected to a lower portion of the body and pumping water stored in the lower portion of the first storage space into the upper portion of the first storage space; and a gas exhaust portion generating a suction force in a state where the gas exhaust portion is connected to the outlet and allowing gas stored in the second storage space to be exhausted as water stored in the first storage space rises into the second storage space due to an internal pressure differential between the first storage space and the second storage space.
