WATER PURIFIER Russian patent published in 2008 - IPC C02F1/22 

FIELD: technological processes, water treatment.

SUBSTANCE: invention is related to devices for aftertreatment of running, artesian, well and other conditionally drinking water. Water purifier for preparation of melted drinking water includes the following zones installed serially in one longitudinal vessel: zone of water freezing with annular freezing chamber, zone of admixtures displacement from ice front and concentration of admixtures in the form of brine, and zone of water transition from solid state into liquid with annular heating element, separate nozzles for discharge of admixtures in the form of brine and melted drinking water, which are installed in the bottom part of the vessel. Water purifier is additionally equipped with driving device of frozen water rod displacement, which is mounted after freezing chamber, and also separating device installed in the center of frozen water rod, which is arranged in the form of pipe and has annular cutting part in the form of toothed crown at the inlet, and expanding profile - at the outlet, forming outlet nozzle for brine displacement. Drive device of frozen water rod longitudinal displacement is arranged in the form of rollers with toothed surfaces that are engaged with frozen water rod through slots in vessel and are arranged along longitudinal vessel perimeter and height. Besides, each roller is equipped with separate drive. Walls of longitudinal vessel are made of stainless material, for instance, steel with anticorrosion coating, bronze, copper, polymer, at that surface that contacts with ice has high purity of roughness.

EFFECT: increase of efficiency and extent of water purity.
