PROBLEM TO BE SOLVED: To mix a deodorizing agent to be sprayed in an exhaust duct, into air containing odor to permit deodorizing by a method, wherein a plurality of deodorizing agent injection nozzles are provided in the exhaust duct, connected to an exhaust fan, so as to be projected while the deodorizing agent is supplied into the nozzles to spray the same. SOLUTION: An exhaust duct 1 is connected to an exhaust fan 2 to communicate with the same to suck air containing odor by the exhaust fan 2 and discharge the same into outdoor air, after deodorizing in the exhaust duct 1. A plurality of deodorizing agent injection nozzles 3 are provided in the exhaust duct 1, so that the tip ends of the nozzles are projected from the duct near the center of the duct 1. A deodorizing agent supplying unit 4 is provided with the deodorizing agent which is diluted with water, into a tank 5 to inject by a pump 6 through the injection nozzles 3. The injected deodorizing agent is injected in a shape of spraying mist by mixing agent compressed air through an air pipeline 7. According to this method, the deodorizing agent sprayed in the exhaust duct 1, is mixed into air flow containing the smell, to permit sure deodorizing. |
