METHOD AND DEVICE TO CONTROL OIL PRODUCT GATHERING FROM WATER SURFACE Russian patent published in 2006 - IPC E02B15/10 

FIELD: means for cleaning or keeping clear the surface of open water from oil or oil products.

SUBSTANCE: device comprises vacuum multiproduct hydrocyclone oil trap with supply nipples coaxial to heavy liquid phase nipple and light liquid phase nipple. The device is provided with nozzles connected to compressor and installed in supply nipples. The nozzles are arranged along generators of cylinder-conical part of hydrocyclone oil trap and spaced apart so that all outer flow may be treated in hydrocyclone oil trap with air sprays generated by the nozzles. The nozzles may be operated so that one, several or all nozzles may work at a time. Water surface cleaning method involves sucking water and oil products in hydrocyclone oil trap in tangential direction; separating oil and oil products in hydrocyclone oil trap by the action of centrifugal force under control of oil product flow to be removed by hydraulic pump. Additional control of oil product flow at hydrocyclone oil trap outlet is carried out by applying finely atomized air thereto. The finely atomized air is sprayed in liquid and atomized air quantity and place of air introduction in hydrocyclone oil trap may be changed in dependence of quantity and properties of oil products entering hydrocyclone oil trap.

EFFECT: increased efficiency of oil and oil product gathering along with extended control range due to improved hydrodynamic characteristics, which improve flow stratification during centrifugal water separation.
