PHOTOCATALYTIC FILTER DEVICE FOR AIR PURIFICATION, BASED ON TITANIUM OXIDE COMBINED WITH COLLOIDAL COPPER AND ZINC

摘要

The invention relates to a photocatalytic filter equipment designed for filtering air, the chamber (2) of which is equipped with inlet (8) and outlet (9) openings for the flow of filtered air and metal plates (3) which are arraged orthogonal to UV tubes (4). The sidewalls of the chamber and the metal plates, after being pre-treated with a copolymer, are coated with titanium oxide modified by colloidal zinc and copper.;This filter device can be used in sequence with for example an air conditioning system.
