ABSTRACT:
A device for the sterilization of liquids by means of ultraviolet radiation whereby a low-pressure high-current mercury vapor lamp is used with a discharge tube as the radiation source wherein the cooling of the lamp is effected by means of an air flow circulating in the device and adjustment of the mercury vapor pressure by heating the cooled air in a heating device and the heating of a cecum-shaped piece of tubing with this heated air. In order to reduce the energy consumption during this heating phase, a mechanism is provided in the device in order to lead a first portion of the cooled air flow directly to the discharge tube of the lamp. A second portion of the cooled air flow, which is smaller in comparison with the first portion, is heated by the heating device and led to the cecum.
