Reactor for disinfecting or preparing a liquid through the combined use of UVC irradiation and ozone and mercury vapour lamp for use in the reactor

摘要

Reactor comprises a liquid container (1) for receiving the liquid to be treated, in which a mercury vapor lamp (2) is arranged for the emission of UVC-radiation, where the mercury vapor lamp comprises a lamp bulb (7) having a longitudinal axis at its ends and comprises electrodes, which are oppositely extending in a closed discharge space, a circumferential gap surrounded by a casting tube, which is permeable to the UVC radiation, a gas inlet (4) for oxygen-containing gas to be ozonized, and a gas outlet (5). Reactor comprises a liquid container (1) for receiving the liquid to be treated, in which a mercury vapor lamp (2) is arranged for the emission of UVC-radiation, where the mercury vapor lamp comprises a lamp bulb (7) having a longitudinal axis at its ends and comprises electrodes, which are oppositely extending in a closed discharge space, a circumferential gap surrounded by a casting tube, which is permeable to the UVC radiation, a gas inlet (4) for oxygen-containing gas to be ozonized, and a gas outlet (5), where the lamp bulb has a first outer diameter in a middle portion between the electrodes and has a second outer diameter, which is greater than the first outer diameter in the region of its ends. An independent claim is also included for a mercury vapor lamp for sterilization or treatment of a liquid through the combined use of UVC radiation and ozone, comprising a lamp bulb having a longitudinal axis at its ends and comprises electrodes, which are oppositely extending in a closed discharge space.
