In the oil industry, the decanter centrifuge plays an indispensable role as one of the core equipment in sludge treatment. The following is a detailed introduction to the application of decanter centrifuge in the oil industry:
Working principle
The decanter centrifuge uses the centrifugal force generated by high-speed rotation to separate the solid particles from the liquid in the mixed liquid. Inside the decanter centrifuge, the sludge mixture enters the drum through the feed pipe. The drum generates a strong centrifugal force during high-speed rotation, causing the solid particles to deposit on the inner wall of the drum, while the liquid flows out of the drum through the weir plate opening to achieve solid-liquid separation.
Application advantages
1. High separation efficiency: The decanter centrifuge can quickly and efficiently separate the three phases of oil, water and solids in the sludge, with a separation efficiency of more than 99%, greatly improving the efficiency and effect of sludge treatment.
2. Large processing capacity: The decanter centrifuge has a compact structure and a large single-machine processing capacity, which can meet the needs of the oil industry for large-scale sludge treatment.
3. High degree of automation: The equipment adopts PLC control to achieve automatic operation, easy operation, reduce manual intervention, and improve production efficiency and safety.
4. Strong adaptability; the decanter centrifuge has a wide range of adaptability to materials and can handle sludge of different properties, such as sludge with high oil content, high water content or high solid particle content.
5. Stable operation: The decanter centrifuge can maintain balance when running at high speed, reduce vibration and noise, and improve the stability and service life of the equipment.
Application areas
1. Oilfield exploitation: During the oilfield exploitation process, a large amount of sludge and wastewater will be generated. The decanter centrifuge can effectively separate the oil, water and solid phases in these sludge and wastewater, recover the useful resources and reduce environmental pollution.
2. Refinery: The refinery also produces a large amount of sludge and wastewater during the production process. The decanter centrifuge can separate the oil, water and solid phases in these sludge and wastewater, recover the oil resources and reduce the discharge of wastewater.
3. Oil tank cleaning: During the oil tank cleaning process, a large amount of sludge and sewage will be generated. The decanter centrifuge can separate the oil, water and solid phases in these sludge and sewage, recover the oil resources and reduce the discharge of sewage.
