Title:
DEODORIZING METHOD AND DEODORIZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/082380
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a deodorizing method and a deodorizing device, which are capable of eliminating an odor with high efficiency regardless of the kind of the causative substance of the odor.
A deodorizing method according to the present invention eliminates an odor by irradiating a gas to be treated with ultraviolet light, and is characterized in that: the ultraviolet light includes light having a spectrum wherein the width of a wavelength band having a ratio of the spectral radiation intensity of 0.5 or more relative to the maximum value of the spectral radiation intensity is 10 nm or more within the wavelength range of 200-260 nm; and a rare gas fluorescent lamp, which is composed of an arc tube, a pair of electrodes that are provided on the outer circumferential surface of the arc tube, a phosphor layer that is provided on the inner circumferential surface of the arc tube, and a rare gas sealed within the arc tube, and wherein the phosphor constituting the phosphor layer is composed of one or more substances selected from the group consisting of praseodymium-activated lanthanum phosphate and praseodymium-activated yttrium aluminoborate, is used as an ultraviolet light source.
