Abstract

An apparatus for irradiating fluids includes a conduit (11) through which the fluid flows, in which a static mixer (21) is disposed and which passes through a cooling vessel (16) having an annular cross-section. This arrangement is surrounded by several U-shaped fluorescent tubes (19, 20), whose legs, extending parallel to the conduit, are distributed around the periphery of the conduit (11). The mixer (21) effects a highly turbulent flow, such that all parts of the fluid are uniformly irradiated with radiation. If the fluid is a glue which is to be preactivated by the radiation, then the turbulent flow and the reaction rate, which is reduced by the cooling, retard the setting of polymerized fluid components on the inner wall of the reaction conduit, and thereby also inhibit the gradual blockage of the conduit (11).
