　　Crude oil refining and purification centrifuge, horizontal oil-water slag three-phase centrifuge, crude oil refining and slag removal separation equipment

　　This series of three-phase centrifuges consists of two liquid phases and one solid phase, which enter the centrifuge and are expanded several thousand times by the centrifugal force field. The solid phase settles under the action of centrifugal force, and the two liquid phases also separate into layers, thus achieving solid-liquid three-phase separation, and are discharged from the machine body through special mechanisms. The entire feeding and separation process is continuous, closed, and automated.

　　Main structure:

　　It is mainly composed of components such as drum, screw, differential, frame, housing, and motor. The drum adopts a double cone angle design, and the inner wall of the drum is specially designed with longitudinal concave convex grooves to improve the efficiency of spiral conveying of solid phase. The working surface of the spiral blade has a hard alloy protective layer, which effectively improves the wear resistance life of the spiral blade. The main motor is controlled by the main frequency converter, and the auxiliary motor is controlled by the auxiliary frequency converter. The frequency of the motor can be adjusted arbitrarily. The power supply of the auxiliary frequency converter is provided by the main frequency converter, known as DC common bus power supply. DC common bus power supply realizes energy feedback when the auxiliary motor is in the working state of the generator, which can effectively save electricity.

　　The horizontal oil-water slag three-phase centrifuge separation process for refining and purifying crude oil: When the material to be separated is transported by the feed pump to the centrifuge drum, the high-speed rotating drum generates strong centrifugal force to settle solid particles with higher density than the liquid phase onto the inner wall of the drum. Due to the different rotational speeds of the spiral and the drum, there is relative motion between the two (i.e., adjustable speed difference), and the solid (slag) with higher density settles onto the drum wall. Two phases of clear liquid with different densities form concentric cylinders, with the lighter liquid phase in the inner layer and the heavier liquid phase in the outer layer. The thickness of different liquid rings can be adjusted by adjusting the liquid plate (i.e. the water content in the oil or the oil content in the water can be adjusted). The slag deposited on the wall of the rotary drum is transported by the screw conveyor to the cone end of the rotary drum, and discharged into the solid material tank from the discharge port. Water and oil are discharged from their respective outlets, and the entire three-phase separation process of oil, water, and slag is automatically fed and discharged.

　　The horizontal oil-water slag three-phase centrifuge is also widely used for clarifying or removing slag and impurities in oil field aged oil, waste engine oil, catering waste oil, crude oil extraction, and other processes.
