Oil sludge treatment equipment - Three phase horizontal screw centrifuge

Description :

　　Oil sludge treatment equipment - Three phase horizontal screw centrifuge

　　The working principle of the three-phase separation horizontal spiral discharge settling centrifuge is basically similar to that of the ordinary horizontal spiral discharge settling centrifuge. After two liquids and one solid enter the centrifuge, the solid-liquid specific gravity difference is utilized, and the centrifugal force field is used to expand it by thousands of times. The solid phase is settled under the action of centrifugal force, and the two liquid phases are also layered, thus achieving solid-liquid three-phase separation, and being discharged from the body under the action of special mechanisms. The entire feeding process and separation process are continuous. Sealed, automatically completed.

　　The working principle of the three-phase separation horizontal spiral discharge settling centrifuge is basically similar to that of the ordinary horizontal spiral discharge settling centrifuge. After two solids and one liquid enter the centrifuge, the solid liquid solid specific gravity difference is utilized, and the centrifugal force field is used to expand it by thousands of times. The heavy solid phase is settled under the action of centrifugal force, and the liquid phase is also layered, while the light solid floats up, thus achieving the separation of solid liquid solid three-phase and being discharged from the body under the action of special mechanisms. The entire feeding process and separation process are continuous. Sealed, automatically completed.

　　The energy-saving design of the three-phase horizontal screw centrifuge for oil sludge treatment equipment is reflected in the following aspects:

　　1. Energy saving design of slag discharge outlet: The bottom of the cone section of the horizontal spiral centrifuge drum is uniformly opened with slag discharge outlet along the circumferential direction. The slag discharge outlet is processed parallel to the tangent direction into a flat surface, avoiding collision and wear between solid materials and the slag discharge outlet before leaving the drum. During the slag discharge process, solid materials can leave the rotating drum earlier, saving energy.

　　2. Energy saving design of overflow port: The large end of the centrifuge drum is equipped with an overflow port, which is fitted with an overflow plate that can adjust the depth of the liquid pool. The liquid phase material leaves the high-speed rotating drum directly, reducing the acceleration of the drum on the liquid phase material and saving energy. Applied in clarification situations, the effect is more pronounced.

　　3. Energy saving design of the drive system: The horizontal screw centrifuge adopts a dual motor dual frequency conversion energy feedback drive system, consisting of a main motor and an auxiliary motor each equipped with a frequency converter. Under the action of differential speed, the energy regenerated when the auxiliary motor is in the generating state is fed back to the main motor through a DC common bus, saving energy.
