CONTINUOUS OPERATION WATER STERILISER Russian patent published in 2022 - IPC A61L2/12 

FIELD: water treatment.

SUBSTANCE: invention relates to the field of water sterilisation. Continuous operation water steriliser, wherein in order to heat the water, in a terminal coaxial UHF apparatus with a generator at a frequency of 2,450±50 MHz and a power of 700 W, a vessel shaped as an expanding cone with a bottom and a neck in the form of a cup, the bottom whereof is supported by an internal coaxial conductor and the external size is limited by an external coaxial conductor. The bottom of the cup herein has an internal diameter d equal to 0.06–0.15 of the length of said UHF wave and a diameter D by the upper edge of the cup (neck) equal to 0.18–0.47 of the length of said UHF wave; a turbulator made of a radiopaque material with disks of a diameter equal to half the diameter of the cup at the location of the disk is installed on the axis of the cup; liquid is entered into the cup through a channel in the turbulator; a silver wire is placed along the external diameter of the disks of the turbulator, making a complete revolution around the axis of the cup in a spiral, wherein one or more spirals are placed, but said spirals do not create UHF energy reflection above the acceptable values; the steriliser comprises a recuperator, valves for selecting both heated and cooled liquid, a drainage pipeline, and a recycling circuit bypassing the container with the initial liquid; the internal surfaces of the pipelines and the shutoff valves are coated with a hydrophobic material.

EFFECT: reliability of sterilising liquids due to the destruction of spore-forming forms of microorganisms and prevented recontamination of the liquids.
