Odour removal unit comprising UV lamp controlled in response to ozone levels

摘要

The unit comprises input and output conduits, ultraviolet (UV) light 14, 16 and ozone meter. The rate of ozone generation by the ultra-violet lamp is controlled in response to the concentration of ozone detected in the output conduit. The inner surfaces of the unit are preferably coated with reflective material or material which enters a super-hydrophilic state when exposed to UV light 16 of 254 μm, wherein the super-hydrophilic titanium dioxide in the anatase phase acts as an oxidation catalyst. The inner surfaces of the unit are preferably corrugated. The UV light is preferably a pellet amalgam lamp with shield. The conduits preferably contain filters, especially a mesh or perforated sheet. The unit is preferably a removable cartridge 12. The unit removes malodours produced by cooking food in the catering industry.
