DEVICE FOR REVERSEOSMIC CLEANING OF SANITARY-HYGIENIC WATER IN A CLOSED CIRCUIT UNDER THE CONDITION OF NEVOSMOSTI

摘要

The utility model refers to the field of life support systems for crews of spacecraft (spacecraft, orbital stations), as well as individual households, namely to regenerative water supply systems.;The technical result: an increase in the degree of water extraction is provided during a continuous process of regeneration under conditions of weightlessness, ensuring a long service life.;This technical result is achieved due to the fact that a device for reverse-osmosis purification of sanitary-hygienic water formed in the water treatment or washing compartment, which includes a receiving capacity of variable volume, a coarse pre-filter, a reverse osmosis module, a receiving tank of purified water, pumps , connected by means of flexible pipelines, equipped with shut-off and control valves, the device being designed to circulate contaminated water, characterized in that the supply for supplying air from the environment is connected to a water treatment or washing compartment, the outlet channel of which is connected to the inlet of the gas-liquid mixture separation unit with a centrifugal separator whose output is connected to the input of a receiving capacity of variable volume, having in its composition a package of polymeric material, the output of which is connected to the input of a constant volume concentration tank, whose output through the coarse pre-cleaning filters and fine pre-cleaning on the high pressure pump discharge line is fed to a vortex separator whose output is connected to the input of a reverse osmosis filter, which have connections to the input of a constant-capacity concentration vessel and to the input of a silver ionizer, the output of which is connected to a tank of purified water, The outlet is connected to a water treatment or washing station. the output of which through coarse pre-cleaning filters and fine pre-cleaning on the high-pressure pump discharge line is fed to a vortex separator whose output is connected to the input of a reverse osmosis filter whose outputs have connections to the input of a constant-capacity concentration vessel and to the input of a silver ionizer whose output is connected to a container of purified water in which a branch with a pump is installed, the output of which is connected to the input of an ultraviolet disinfector, the output of which is connected to a compartment th water treatment or washing. the output of which through coarse pre-cleaning filters and fine pre-cleaning on the high-pressure pump discharge line is fed to a vortex separator whose output is connected to the input of a reverse osmosis filter whose outputs have connections to the input of a constant-capacity concentration vessel and to the input of a silver ionizer whose output is connected to a container of purified water in which a branch with a pump is installed, the output of which is connected to the input of an ultraviolet disinfector, the output of which is connected to a compartment th water treatment or washing.
