Abstract
An electronic air purifying method and apparatus whereby the air to be purified is introduced into the apparatus and oxygen molecules of said air are first transformed into the allotropic form of oxygen by a low pressure mercury ultra violet radiating device and then said allotropic form of oxygen is decomposed to nascent oxygen by heat. The so created nascent oxygen oxidizing instantaneously impurities contained in the air moving through the air purifying apparatus.
Claims4
An apparatus for purifying and sterilizing the air in a space and for decomposing ozone within said air comprising;
- a tubular housing having top and bottom sections with a horizontal cross section smaller than its vertical cross section and comprising a flow path for air and air-ozone mixtures;
- an air inlet in said bottom section and air outlet in said top section;
- an ultra violet radiating device placed in said bottom section of said housing in proximity to said air inlet for creating within said bottom section ozone in air of ambient temperature, and for emitting germicidal radiation;
- a heating device placed in said top section of said housing above said ultra violet radiating device for heating and decomposing ozone in said air-ozone mixture, and for supporting air flow through said tubular housing;
- means for connecting said ultra violet radiating device and said air heating device to an electric power supply;
- means for regulating the temperature of said heating device and of said air-ozone mixture in said top section of said housing;
- the air flow path in said housing comprising in the bottom section a germicidal radiation and ozone forming region and in the top section an ozone decomposing, impurities oxidizing and molecular oxygen forming region.
A method of purification and sterilization of air by exposing said air to ultra violet radiation followed by application of heat, whereby air of ambient temperature and with ambient amounts of ozone and impurities is first exposed to ultra violet radiation in the 2537 Angstroms wave band and in the 1849 Angstroms wave band;
- the 2537 Angstroms wave length having a sterilizing effect and the energy of the 1849 Angstroms wave band transforming oxygen molecules in said air into the allotropic form of oxygen, ozone;
- creating a continuously flowing and turbulent air-ozone-impurities mixture, which thereafter is exposed to heat;
- said heat decomposing the ozone molecules in said air-ozone-impurities mixture to nascent oxygen;
- said nascent oxygen practically instantaneously reacting with impurities by oxidizing them and at the same time reacting with neighboring oxygen atoms to form new stable oxygen molecules.
