Title:
PHOTOCATALYST DEODORIZATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/162059
Kind Code:
A1
Abstract:
Disclosed is a long-life photocatalyst deodorization device (1) which effectively excites photocatalysts over the entire surface of a photocatalyst sheet and is capable of maintaining deodorization performance over a long period. Substrates (5 and 7) upon which vent holes (4) have been provided are disposed in parallel, and upon at least one substrate (5) of the two substrates, LEDs (3) are mounted. Between the two substrates, photocatalyst sheets (6) constituted by woven glass fiber material (6A) carrying photocatalyst particles (6B) and a frame (6C) supporting the material are disposed. The photocatalyst sheets and the two substrates are fixed to a housing (8), whereupon emitting surfaces of the LED light sources for exciting the photocatalysts and the photocatalyst sheets are disposed in parallel. Air fed from the vent holes is caused to pass through the photocatalyst sheets. The photocatalyst sheets are constituted by bundling glass fibers and weaving the fibers in a crisscross manner so as to have a predetermined aperture ratio such that ventilation is possible under low wind speed. The photocatalyst particles are mechanically held in contact between the glass fibers of the photocatalyst sheets.
