　　Overview of Oil Sludge Treatment Equipment

　　Abbreviation: Spiral Discharge Centrifuge

　　There are two types of spiral discharge centrifuges: discrete and horizontal, but in industry, horizontal is mainly used, abbreviated as "horizontal screw".

　　The horizontal spiral discharge centrifuge is mainly composed of a high-speed drum, a screw and differential that rotate in the same direction as the drum and have a slightly higher or lower speed than the drum. When the suspension to be separated enters 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 a relative motion (i.e. speed difference) between the two. The relative motion between the spiral and the drum is used to push the solid phase deposited on the inner wall of the drum towards the outlet at the small end of the drum, and the separated clear liquid is discharged from the other end of the centrifuge. The function of the differential (gearbox) is to create a certain speed difference between the drum and the screw.

　　The main dehydration process can be summarized as follows:

　　The suspension enters the drum from the feed pipe, and the solid particles are accelerated and settled on the inner wall of the drum under the action of centrifugal force. The settled particles are pushed by the blades of the screw conveyor and are discharged from the settling zone (straight section) through the drying zone (cone section) to the solid phase outlet; The clarified liquid phase overflowed from the overflow hole. Thus achieving automatic and continuous separation of solid and liquid phases.

　　Treatment process of oil tank cleaning and sludge treatment equipment in the oil tank area

　　The mixture of oily sludge is sent to the vibration drying treatment module for full flow solid-liquid separation and vibration dehydration drying. The liquid phase is sent to the rapid settling treatment module for natural settling and solid-liquid separation. The separated liquid phase (clear water) is returned to the drilling team's solid control system to participate in the drilling cycle. The settled concentrated solid-liquid mixture is sent to the centrifugal separation treatment module for solid-liquid separation, and the separated liquid phase is returned to the rapid settling device. The solid phase separated by the vibration drying processing module and centrifugal separation processing module mentioned above is transported by the drilling cuttings collection and transportation module to the designated storage location.
