APPARATUS FOR CLEANING WATER RESERVOIRS FROM PETROLEUM PRODUCTS Russian patent published in 2021 - IPC E02B15/04 E02B15/10 B04C5/12 B04C5/14 

FIELD: treatment of water.

SUBSTANCE: invention relates to the field of cleaning the surface of water reservoirs from petroleum products. Proposed is an apparatus for cleaning water reservoirs from petroleum products. The apparatus comprises a petroleum intake funnel with a feed branch pipe and a vacuum hydraulic cyclone. The petroleum intake funnel is made in the form of a truncated cone closed with a bottom, a cylindrical-conical body of the vacuum hydraulic cyclone is placed on the axis of the body. The feed branch pipe is made in the form of curvilinear guiding plates one of the ends whereof adjoins the conical surface of the petroleum intake funnel and the second end forms a fragment of the cylindrical part of the body of the vacuum hydraulic cyclone. The gaps between the top of the guiding plates and the cylindrical part of the body of the vacuum hydraulic cyclone are closed with crescent-shaped covers. The drainage branch pipe for the heavy phase - water - is made in the form of a pipe mated with the top of the conical part of the body of the vacuum hydraulic cyclone. The drainage branch pipe for the light phase is made in the form of two telescopically connected pipes, wherein one of said pipes is rigidly fixed in the centre of the bottom of the petroleum intake funnel, and the second perforated pipe is passed through the hole in the upper part of the cylindrical body of the vacuum hydraulic cyclone, configured to move.

EFFECT: invention provides an increase in the efficiency of work and a reduction in the dimensions of the apparatus.
