The utility model discloses equipment for separating residual catalyst granules in catalytic cracking oil slurry. The equipment is of a convex structure with two symmetric sides, filtering nets (5) are respectively arranged on two sides of the equipment, sealing spaces (2) are formed between the filtering nets (5) and two sides of the equipment, telescopic shafts (7) are arranged between the filtering nets (5) and the side walls of the equipment; oil slurry outlets (8) are formed in the bottom of two sides of the equipment; an oil residue outlet (11) is formed in the center of the bottom of the equipment; an oil slurry inlet (3) is formed in the side wall of the top of the equipment; a flashing liquid outlet (4) is formed in the top of the equipment; sliding plates (6) are arranged at the upper ends and the lower ends of the filtering nets (5); one end of each sliding plate is connected with each filtering net (5); the other ends of the sliding plates extend to the side surfaces of the equipment; and ultrasonic modules (10) are arranged on the sliding plates (6) at the bottom of the equipment. Due to the adoption of the ultrasonic modules and back flashing, the problem that the filtering nets are blocked can be effectively solved, and the equipment is simple in structure, scientific and reasonable, and is convenient to popularize and use.
