Abstract
An apparatus and method for ultraviolet irradiation of air for the purpose of removing contaminants from that air is disclosed. A U-shaped ultraviolet bulb enshrouded within a quartz tube provides enhanced contaminant destruction characteristics. By combining a plurality of those bulbs in a chamber that is of polished aluminum, and further combining aluminum filters therewith, added irradiation enhancement is achieved.
Claims44
An apparatus for purging impurities from ambient conditions, comprising, in combination:
- a source of ultraviolet radiation in operative communication with the ambient conditions;
- and
- means for maintaining said source in a preferred substantially constant temperature range of between approximately 80° F. to 90° F. to promulgate radiation emissivity for purging substantially all impurities from the ambient conditions.
A method for sterilizing air, the steps including:
- passing the air adjacent a source of ultraviolet light;
- and
- maintaining the ultraviolet light at an optimal operating temperature between 80° F. to 90° F. by preventing temperature drop of the ultraviolet light's optimal operating temperature caused by the passage of the air over the light.
A chamber for cleansing ambient air, comprising, in combination:
- an air inlet;
- an air outlet;
- said chamber interposed and communicating between said inlet and outlet;
- a source of radiation in said chamber, said chamber imperforate to the radiation;
- a temperature maintaining envelope circumscribing said radiation source to maintain the temperature approximately 80° F. to 90° F.;
- said chamber having an interior surface with means for reflecting substantially all the radiation;
- and
- further comprising a pair of filters, one said filter mounted up stream and one said filter mounted downstream from said radiation source wherein said filters have restrictive means on a surface thereof facing said radiation source.
An air cleansing device, comprising in combination:
- a chamber;
- an air inlet leading into said chamber;
- an air outlet leading out of said chamber;
- said chamber including sidewalls interposed and communicating between said inlet and outlet;
- an ultraviolet radiation source including a UV bulb coupled to said chamber and stationed between said inlet and said outlet;
- means for igniting said bulb;
- means for impeding an air flowpath between said inlet and said outlet to alter flow rate in said chamber;
- wherein said flowpath impeding means includes two filters mounted about said UV bulb, one said filter adjacent said inlet and one said filter adjacent said outlet and said filters include a woven mesh with a finer density pore size facing said UV bulb.
