<p>PROBLEM TO BE SOLVED: To restrain performance of a photocatalyst member from being deteriorated by dust passing through a dust collector. SOLUTION: A charger 30 imparts a charge to dust in the air, and the dust imparted with the charge by the charger 30 is collected by a dust collector 40. A cylindrical ultraviolet lamp 50a is arranged in an air downstream of the collector 40, a deodoring equipment 70 receives an ultraviolet ray from the lamp 50a and is activated to decompose oder components in the air. A dust collecting electrode 60a connected to the ground is provided in an outer wall side of the ultraviolet lamp 50a. The dust passing through the collector 40 is collected by the electrode 60a.</p> |
