10. A method for using the oil recovery device in the oily sewage after electric desalting in the oil field oil recovery and oil refinery according to any one of claims 1-9, which comprises the following steps:
step 1, when the sewage filtering device is used, sewage is introduced from an upper end opening of a filtering box (2), particulate matters and sundries in the sewage are filtered after the sewage passes through a filtering plate (7), the sundries fall into a sundry collecting box (4) under the action of an inclined filtering plate (7), and a filtering net (5) is arranged to enable the sewage seeped from the impurities of the sundry collecting box (4) to flow back into the filtering box (2);
step 2, after the sewage enters the filter tank (2), when the water level exceeds the height of the discharge elbow (3), the discharge elbow (3) starts to drain water, when the sewage in the filter tank (2) passes through the aggregation induction demulsification filter cotton plate (33), oil can be adsorbed on the aggregation induction demulsification filter cotton plate (33), and when the buoyancy of the oil adsorbed on the aggregation induction demulsification filter cotton plate (33) is large enough, the oil floats upwards to form floating oil;
step 3, starting a motor (13), wherein the motor (13) drives a worm (18) to rotate, the worm (18) drives a worm wheel (26) to rotate, the worm wheel (26) drives a rotating shaft (15) to rotate, a connecting shaft (27) is driven to rotate under the action of a gear (28), the connecting shaft (27) drives a driving disc (11) to rotate, the driving disc (11) drives a piston rod (9) to reciprocate by rotating, a piston (36) in a suction cylinder (8) is driven to reciprocate and suck, floating oil at the upper end of a filter box (2) is pumped out and sent to water and oil resistant fiber cloth (20), and then the floating oil is discharged to the water and oil resistant fiber cloth (20) through an output pipe (24) and a discharge pipe (23);
step 4, simultaneously, the drive plate (29) rotates the drive bar frame (22) and swings, and then the drive supports skeleton (21) and swings, promote the filtration of oil slick, water hinders oily fibre cloth (20) and filters water, and filter out the oil and flow into in collecting vessel (16) from the exit of water hinders oily fibre cloth (20) and keep in, the water of filtering falls into in flowing back cover (17) and enters into water tank (1), simultaneously through long-term oil absorption cotton (34) of setting in water tank (1), can carry out further processing to the sewage that discharges return bend (3) and flowing back cover (17) discharge when using, adsorb remaining oil in the sewage, then sewage passes through outlet (35) and discharges.
