Abstract:
A device (10) for the UV irradiation, in particular for the disinfection of flowing liquids in the form of purified waste water, the device (10) being arranged in an irradiation chamber and comprising at least one support frame (12) having a plurality of UV modules (14) which are arranged parallel to one another along the flow direction (A) of the purified waste water, and each UV module (14) being designed as an immersible radiator and being in each case formed by a UV radiator (26) which is designed as a mercury low-pressure radiator and is enclosed by a sleeve tube (28) which is transparent to UV rays, each UV module (14) having an annular gap between said UV radiator and said sleeve tube, said UV radiators being connected to an electrical power source through an electronic control system, said device being characterized in that each UV module (14) is assigned an irradiation space (24) having a polygonal cross section, the center of which is also the center (18) of the UV radiator (26) and which in each case extends from the center (18) half-way to the neighboring UV modules (14) being arranged in such a way that the centers (18) of a number of neighboring UV modules (14) form the vertices of a polygon (20), the area of which corresponds to the sum of the cross-sectional area (F1) of a UV module (14) and the cross-sectional area (F2) of the irradiation space (24) of a UV module (14), and in that the spacing of the UV modules (14) from one another is selected in such a way that the cross-sectional area (F2) of the irradiation space (24) of each UV module (14) is no more than 10 times greater than the cross-sectional area (F1) of the UV module (14).
