CLEANING METHOD OF WATER RESERVOIR SURFACE AGAINST OIL PRODUCT CONTAMINANTS (VERSIONS), AND DEVICE FOR PUMPING OF OIL PRODUCTS FROM WATER RESERVOIR SURFACE TO RECEIVING ACCUMULATOR

摘要

FIELD: oil and gas industry.;SUBSTANCE: as per the first cleaning method of water reservoir surface against oil product contaminants, localisation of a contaminated section of water reservoir is performed by creation of directed movement of oil products 2 by means of controlled air flow 3 to convex surface 7 of intake device 6. Convex surface 7 of intake device 6 is restricted with flanges on lateral sides. First, continuous jet water flow 10 is supplied under pressure to convex surface 7 in direction of air flow 3. Water flow is shaped by means of slot nozzle 11 of hydraulic pump 12. Hydraulic pump 12 is located below boundary line of water - oil product phases. Flow of oil products is discharged with continuous jet water flow 10 to receiving accumulator 9. Receiving accumulator 9 is located behind convex surface 7 with formation of a slot between them, through which continuous jet water flow 10 is discharged to water reservoir 1. As per the second method, localisation of contaminated water reservoir section is performed and oil products are discharged to the receiving accumulator with pumping-out device 18. Localisation of the section is performed by creation of directed movement of oil products 2 to the intake device by means of controlled air flow 3. Intake device is made in the form of oil trap 17 with tangential intake of oil products. Oil trap 17 is made in the form of open annular onboard enclosure 19 with grabbing jaw 20. One side 21 of grabbing jaw 20 is made at a tangent to open annular onboard enclosure 19 and by its direction to water reservoir 1 surfaces towards opposite air flow 3. Device 18 for pumping-out of oil products 2 from the water reservoir surface to the receiving accumulator includes cylindrical housing 23, and drive 24 with vertical rotation axis. Cylindrical housing 23 forms cavity 25 of the receiving accumulator. Housing 23 is mounted in wound spiral 28 of strip 27. Strip 27 of spiral 28 is located at an angle to outer surface 29 of cylinder 23 and lower edge 30 of strip 27 of spiral 28 is tightly pressed to outer surface 29 with formation of spiral chute 31.;EFFECT: improving cleaning efficiency of water reservoir surface against oil product contaminations.;7 cl, 5 dwg
