Photocatalytic devices

摘要

A photocatalytic device includes a housing with inlet and outlet openings. Hydrated multi-metallic catalyst substrate(s) disposed within the housing support a hydroxyl radical reaction with water vapor and ultraviolet light from a source in the housing, resulting in hydro peroxides and hydroxyl ions. At least one ion generator disposed in the housing provides ions. A fan disposed within the housing causes air to enter the inlet opening, circulate through the catalyst substrate(s), and exit the outlet opening, carrying the ions. A power converter disposed in the housing is operatively coupled to a power connector adapted to accept a plurality of plugs or cords. Each plug or cord is configured to plug into a corresponding conventional outlet to supply a corresponding conventional alternating current voltage at conventional cycles to the power converter for powering the ultraviolet light source, ion generator(s) and fan.

1. A photocatalytic device, comprising:
a housing having an inlet opening and an outlet opening; one or more catalyst substrates disposed within the housing; an ultraviolet light source disposed within the housing and adapted to provide ultraviolet light to the one or more catalyst substrates; a fan disposed within the housing and adapted to cause air to enter the housing via the inlet opening, circulate through the one or more catalyst substrates within the housing, and exit the housing via the outlet opening; and a power connector defined in the housing and adapted to accept a plug or cord configured for plugging into a corresponding conventional outlet supplying a corresponding conventional alternating current voltage at conventional cycles for powering the ultraviolet light source and the fan.
