FIELD: water treatment.
SUBSTANCE: invention relates to compact devices for water purification to obtain drinking water with improved biological and physical properties and can be used for post-treatment in systems for treating waste water of different origin, as well as be used in medicine, food industry, agriculture and other fields. Vortex conoidal annular ejector comprises cylindrical chamber with swirler and cavitator, water feed and discharge branch pipes. Cavitator is made in the form of conoidal funnel adjacent to the outlet zone of the swirler so that water can pass in the convergent cavity formed with the outer surface of the funnel and the inner surface of the chamber. Swirler and conoidal funnel are located in series with possibility of straight-flow movement of water. Ejector is equipped with longitudinal channel for air supply to inner cavity of conoidal funnel. Conoidal funnel in outlet zone is equipped with end disc installed with gap relative to end zone of funnel for air passage, as well as with clearance relative to inner surface of chamber for water passage along entire outer perimeter of end disc.
EFFECT: invention contributes to improving the operation of a compact water purification device by increasing the efficiency, productivity and quality of water purification.
