Title: Airborne impurities oxidised by UV rays - focussed by reflector without deposits forming on UV source
Inventor: SUMMER HERFORD DR
IPC: B01D53/34
Filed: 1973-04-13
Abstract: Chemical reactions are effected in a medium, in particular impurities in air are oxidised, by a number of UV units arranged in a star pattern about a centre. Each unit consists of an elliptical mirror with a truncated outer (radially outer w.r.t. the centre of the star) end so that the outer focal point is outside the truncated end. At the other radially inner, focal point a U.V. source (esp. an L.P. mercury vapour tube) generates the U.V. radiation which is thus focussed at the first focal point outside the reflector, where it can be absorbed by osmogenic and other molecules in the air and O2 molecules to give nascent oxygen which thus oxidises the impurities. A non-turbulent air curtain is generated inside each elliptical mirror by air outlets near the open end, pref. assisted by a compressed air supply to all mirrors from a common central pipe.
