    Waste Oil Water Solids Oil Sludge Centrifuge Three Phase Variable Frequency Technology

    Waste Oil, Water, Solids 3 phase Separation Oil Sludge Centrifuge

    The decanter centrifuge is for continuous separation of liquid-solid systems consisting of liquid and solids. Stock liquid is brought into the bowl through a centrifugal pump. Solid matter settles into outer larger by the centrifugal force. The settled sediment is pushed into the drying area at the cone of the bowl by rotary difference between spiral and bow land discharged from the outlet. The liquid phase flow out from the liquid outlet.


    The drum and scroll conveyor are made of stainless steel and titanium resisting corrosion. The scroll conveyor was coated with wearable alloy or welded with alloy plate. Stepless speed regulation for the bowl. Step or stepless speed regulation for scroll's differential speed. Simple lubrication. Safety protection: rotation rate detection over, vibration protection, motor overload and overheat protection, protection for scroll when zero differential speed occurs.


    For the highly sticky materials, it can add the hydraulic differential gear to stabilize.The centrifuge is a specially developed continuous Solid-Bowl horizontal Scroll. Discharge centrifuge for effective separation of slurries into liquid-solid phases/liquid-liquid-solid phases, with the application of centrifugal sedimentation principle.

    Production of oily sludge
    Sludge treatment is a complete set of production process, using the principle of oxidative demulsification and centrifugal separation. Its main equipment is composed of dosing system, feeding system, separation system, conveying system, and control system.
    After the oily sludge is collected and heated by steam, a suitable number of additives like demulsifier and active agent are added in it, so that the oily water in the emulsified state is broken. After demulsification, a high-efficiency LWS series three-phase centrifuge is adopted to realize the continuous separation of oil, water, and slag in the oily sludge, and the water separated and the oil-water mixture not demulsified are directly sent to the sewage treatment system for treatment. Then, a LW series two-phase centrifuge with high efficiency is used for dehydration. The crude oil residue in the dehydrated slag phase can be recovered by the combustion or thermal desorption process. The separated crude oil is collected and then purified by a three-phase flottweg separator. The purified oil can be reused.
    Separation performance:
    1, About 80~90% oil can be recovered (relating to oil density, demulsification effect, temperature, etc.), and the recovered oil can be used for refining purpose after further purified by the flottweg separator;
    2, The water content of the oil phase after separation can reach ≤3 ~ 5%;
    3, The dryness of the slag phase after centrifugation can reach 40 ~ 60%, and its total volume is reduced by over 80% compared to that before separation;

    Technical descriptions of the centrifuge
    Extremely low infrastructure investment and good on-site operating environment
    Compared with the conventional filter-type equipment (plate-and-frame filter, belt machine, etc.), the high-performance centrifuge is compact and efficient, covering only about a third of land, needless of auxiliary gas source, high-pressure water, and with simpler pipe structures at the inlet and outlet. Moreover, the operation environment is more humanized, and the skid-mounted integrated device has the characteristics of compact structure, convenient installation, low requirements for infrastructure, and convenient movement. The centrifuge is widely used in the harmless treatment of oily sludge in oilfield drilling.
    Stable operation, low failure rate, and low maintenance cost
    Compared with the filter type equipment, the centrifuge does not require any filter cloth or filter screen, so as to avoid the trouble of clogging and of replacing the filter cloth. The operation and maintenance costs of the equipment are low.
    Modular design, easy to operate
    Our design philosophy: To lower the requirements on the skills, educational level, and labor intensity of operators, and realize one-button start and stop of the control system, fault self-diagnosis, and safety self-protection.
    Operator configuration and labor intensity
    The high-performance centrifuge is an automatic and continuous working mode for feeding-separating-slag (liquid) discharging. The whole process requires no human intervention. Multiple sets of equipment require only one inspector (in conjunction with other positions). Unlike frame and plate-and-frame filter, the slag discharging process does not require manual cutting, greatly reducing the labor intensity of the operator.
    Ingenious, unique, and diversified heavy liquid-phase discharging structure
    The heavy liquid phase separated by the three-phase centrifuge can adopt two different liquid discharging modes, namely gravity discharging and discharging through the built-in centripetal pump with pressure, wherein the latter includes liquid layer fixed mode and the online adjustable mode of heavy phase liquid layer, which is selected according to the process conditions.
    High performance wear-and corrosion-resistant cemented carbide
    As the oily sludge contains a lot of hard particles and impurities such as sand, glass, and metal, if the centrifuge does not adopt reliable wear-resistant configuration, its service life and running stability will be seriously affected. The wear-resistant solution is completely targeted. According to the material characteristics (pH value, corrosive substance, solid particle size hardness, etc.), cemented carbide or ceramic can be selected, and the cemented carbide can be either YG6, YG8, or various modified tungsten-cobalt alloys with the hardness of 89~93 (HRA), which can fully meet the application fields of the centrifuge.
    High performance stainless steel
    The high-performance three-phase centrifuge can recover oil by 90%~95% and adapts to the liquid density difference (oil and water comparison) of the gas and oil of different densities (0.1~0.08 g/cm3). The centrifuge needs more than 3000G separation factor to achieve better separation. To ensure the stability and the service life of the centrifuge, high-strength corrosion-resistant duplex stainless steel SAF2205 is used.
    ★ High-dryness screw conveyor and drum structure
    The dehydration of solid particles relies mainly on strong centrifugal force, high-torque screw extrusion force (pushing torque), and ultra-long solid particle dehydration length. The centrifuge can generate centrifugal force exceeding 3000G, 30 ~ 50% higher than the screw pushing torque of common centrifuges. The screw pusher torque, and the drum dehydration length is 10 ~ 20% longer than that of common centrifuges.
    High torque involute planetary gear differential
    The ultra-high pushing torque requires a high-torque involute planetary gear differential as the foundation. The differential equipped on the centrifuge features high torque, high speed, low heat generation, and excellent heat dispersion, which ensure that the centrifuge can be used for a long time and stably.
