Abstract:
A three-dimensional, photocatalytic filter apparatus comprising a plurality of porous filter plates each carrying a photocatalyst for decomposing pollutants in a fluid stream which comes into contact with said porous filter plates, said porous filter plates being arranged in a path of said fluid stream defined by a flow path means such that each porous filter plate is inclined relative to both said fluid stream and a light source, to achieve sufficient contact with said pollutants and sufficient exposure to said light source, whereinsaid flow path means is constituted by a pair of parallel, transparent sheets, and said light source is disposed outside at least one of said parallel, transparent sheets, and each of said porous filter plates is inclined by 15-75.degree. relative to said fluid stream and by 15-75.degree. relative to said light source.
