Product Description

In industries such as petrochemicals and oil storage, a mixture containing oil, water, and solid impurities, known as tank bottom oil, accumulates at the bottom of oil tanks. The effective treatment of tank bottom oil is of great significance for improving oil quality, reducing environmental pollution risks, and realizing the recycling of resources. As a highly efficient separation equipment, the three-phase decanter centrifuge has been widely used in the field of tank bottom oil separation in recent years.

 

The three-phase decanter centrifuge is mainly composed of a drum, a screw conveyor, a differential, a drive system, and a control system. Its working principle is based on the principle of centrifugal sedimentation. When the mixed liquid enters the high-speed rotating drum, due to the density difference of different components, under the action of the centrifugal force field, the solid particles and the water phase with higher density are thrown towards the inner wall of the drum, while the oil phase with lower density accumulates in the center of the drum. There is a certain speed difference between the screw conveyor and the drum. It continuously conveys the solid particles and the water phase settled on the inner wall of the drum to the slag discharge port and the water discharge port of the drum for discharge, while the oil phase is discharged from the overflow port of the drum, thus realizing the three-phase separation of oil, water, and solid impurities.

1. High-Efficiency Separation: The three-phase decanter centrifuge can achieve high-efficiency separation of oil, water, and solid impurities in tank bottom oil in a short time. It has a high separation efficiency, which can significantly reduce the solid content and water content in the treated oil phase, meeting the quality requirements for subsequent oil processing or storage.
2. Continuous Production: This equipment can realize continuous feeding and separation, making it suitable for large-scale tank bottom oil treatment operations. Compared with the traditional batch separation method, it greatly improves the production efficiency and reduces the labor intensity.
3. Strong Adaptability: It can adapt to tank bottom oil of different properties. Whether it is the fluctuation of the oil content in the oily sewage or the change in the type and particle size of solid impurities, the three-phase decanter centrifuge can achieve good separation effects by adjusting relevant operating parameters such as the drum speed and differential speed.
4. Small Footprint: The equipment has a compact structure and a relatively small footprint. For oil tank areas or treatment sites with limited space, it has obvious advantages and can effectively save construction and operation costs.
5. Environmental Protection and Energy Saving: Through high-efficiency separation, the oil content in tank bottom oil is recovered to the maximum extent, reducing resource waste and environmental pollution. At the same time, the equipment has relatively low operating energy consumption, meeting the requirements of energy conservation and environmental protection in modern industries.

 

A large oil storage base has many large oil tanks, and the accumulated tank bottom oil has a large volume and complex composition. In the past, the traditional method of combining natural sedimentation and simple filtration was used for treatment, with poor results. The oil recovery rate was low, and the treated water phase and solid phase still contained a relatively high concentration of oil, posing great pressure on the environment.

 

After the introduction of the three-phase decanter centrifuge, the situation has been significantly improved. First, a detailed composition analysis of the tank bottom oil was carried out, and the operating parameters of the three-phase decanter centrifuge were optimized and adjusted according to the analysis results. During the actual operation, the centrifuge can work stably and efficiently. After treatment, the water content in the oil phase is reduced to less than 1%, and the solid content is also significantly reduced. The recovered oil can be directly reused in the production process. The oil content in the water phase is reduced to meet the environmental protection emission standards and can be safely discharged or further treated. The solid impurities are effectively separated, facilitating subsequent environmental protection disposal.

 

By using the three-phase decanter centrifuge, this oil storage base has not only improved the treatment efficiency and quality of tank bottom oil but also achieved considerable economic and environmental benefits. The value of the recovered oil reaches millions of yuan per year, and at the same time, the high fines and treatment costs that may be brought about by environmental pollution are reduced.

1. Equipment Selection: According to the specific properties of tank bottom oil, such as the content and characteristics of oil, water, and solid impurities, as well as the treatment capacity requirements, reasonably select the model and specification of the three-phase decanter centrifuge to ensure that the equipment can meet the actual production needs.
2. Adjustment of Operating Parameters: During the operation of the equipment, it is necessary to timely adjust parameters such as the drum speed, differential speed, and feed flow according to the change in the composition of tank bottom oil to ensure the best separation effect.
3. Equipment Maintenance: Regularly maintain and repair the three-phase decanter centrifuge, including checking the wear of key components such as the screw conveyor and the drum, and timely replacing vulnerable parts; maintain the lubrication system and sealing system of the equipment to ensure the normal operation of the equipment.
4. Safe Operation: Operators need to receive professional training and be familiar with the operating procedures and safety precautions of the equipment. During the operation of the equipment, strictly abide by safety regulations to prevent accidents.

VI. Conclusion

The three-phase decanter centrifuge has shown significant advantages in tank bottom oil separation. Through the high-efficiency separation process, it realizes the effective separation of oil, water, and solid impurities, providing a reliable solution for the treatment of tank bottom oil in industries such as petrochemicals. With the continuous progress and improvement of technology, the application prospect of the three-phase decanter centrifuge in the field of tank bottom oil separation will be broader, and it is expected to further promote the green and sustainable development of the industry.
