Abstract:
A light-leakage type photocatalyst filter, comprising:a photocatalyst fiber bundle which is formed by longitudinally bundling a plurality of photoctalyst fibers, each composed of a core portion of a photoconductor and a surface layer containing a photocatalyst, and having gaps which are left among the photocatalyst fibers and which provide passages for an object fluid; a casing which includes an intermediate cylindrical portion for accommodating the photocatalyst fiber bundle; an inflow port and an outflow port for the object fluid, each of which is formed in the vicinity of a respective side end of the casing; and a light source for introducing light beams onto at least one end face of the photocatalyst fiber bundle; the casing further comprising: a light introducing window which is composed of a material transparent to the light beams and which guides the light beams onto the at least one end face of the photocalyst fiber bundle; and a reservoir which is located on at least one end side of the casing adjacent to the at least one end face of the photocatalyst fiber bundle and which is coupled to the light introducing window to make pressure distribution of the object fluid uniform on the at least one end face of the photocatalyst fiber bundle.
