ACTIVE PHOTOCATALYTIC OXIDATION

摘要

An active oxidation and purifying system is provided to increase or maximize the rate of photocatalytic oxidation and ambient air purification capacity by providing both direct ultraviolet (UV) light and reflected UV light directed to the surface and apertures of active cell panels coated with a photocatalytic material. In one example, the active cells also include a plurality of apertures disposed in a transverse manner from the first surface to the second surface of the active cell. Furthermore, a first set of the apertures could be disposed about 45 degrees relative to a median axis along the first and second surfaces, while a second set of apertures could be disposed about negative 45 degrees relative to the same median axis in order to increase the surface area impinged by the direct and reflected UV light.

主权项

1. A photocatalytic oxidation system comprising:
a housing comprising:
a proximate end panel;a distal end panel, the housing having a longitudinal direction extending from the proximate end panel to the distal end panel;an upper panel between top sides of both the proximate end panel and the distal end panel;a lower panel between lower sides of both the proximate end panel and the distal end panel, the lower panel being spaced from the upper panel;a first active cell panel positioned between a first side of the proximate end panel, a first side of the distal end panel, a first side of the upper panel, and a first side of the lower panel; the active first cell comprises a first plurality of apertures disposed in a transverse manner from an inner side to an outer side of the first active cell panel;a second active cell panel positioned between a second side of the proximate end panel, a second side of the distal end panel, a second side of the upper panel, and a second side of the lower end panel; the second active cell comprising a second plurality of apertures disposed in a transverse manner from an inner side to an outer side of the second active cell panel;an interior chamber bounded by the proximate end and distal end panels, the upper and lower panels, and the first and second active cell panels;an elongate UV bulb positioned inside the interior chamber and having a center axis that is parallel with the longitudinal direction;a first reflective feature that protrudes inward into the interior chamber from an inner surface of the upper panel, the first reflective feature extends in the longitudinal direction on the inner surface of the upper panel and is configured to reflect ultraviolet (UV) radiation emitted radially from the elongate UV bulb toward the first plurality of apertures and the inner side of the first active cell, as well as toward the second plurality of apertures and the inner side of the second active cell.
