Working Principle of GN Solids Vacuum Pump

The pump operates in a two-phase cycle using compressed air:

1. Vacuum Phase:
   Compressed air creates a high vacuum inside the pump tank, which suctions material into the tank through the suction line.
2. Discharge Phase:
   The valve switches to introduce positive air pressure, pushing the material out through the discharge line.

This simple yet highly effective mechanism ensures continuous and reliable operation.

At GN Separation, we specialize in providing solutions for oily sludge treatment. Our Oily Sludge Treatment System offers a complete process for handling oily sludge from extraction to oil-water-solid separation, ensuring maximum oil recovery and reducing environmental impact.

Comprehensive Treatment for Oily Sludge

Our Oily Sludge Treatment System is a chemical-assisted mechanical separation process designed to handle a variety of sludge types, including those from oil refineries, drilling operations, oil tank cleaning, and industrial waste. The system performs a complete hot washing process that includes the following steps:

1. Sludge Extraction: Oily sludge is collected from sludge pits using GN’s Solid Vacuum Pump or an excavator for efficient removal.
2. Heating and Conditioning: The sludge undergoes stirring, pre-mixing, and conditioning in the Heating Pre-Mixing Tank, ensuring optimal preparation for further treatment.
3. Coarse Particle Screening: The heated sludge is then processed through a High G Vibrating Screen to separate larger particles, which helps prepare the material for finer separation.
4. Secondary Heating and Conditioning: The sludge is treated with a chemical agent to strip oil from the solid phase and move it into the liquid phase.
5. Solid-Liquid Separation: The sludge is pumped to a Decanter Centrifuge for solid-liquid separation, where the solid sludge with less than 2% oil content can be further processed, either biodegraded or sent to pyrolysis/incineration for disposal.
6. Three-Phase Separation: Finally, the sludge is processed through a Three-Phase Disc Separator to separate oil, water, and solid phases. The recovered oil is ready for sale, while the water can be reused for hot washing, and the remaining solids are disposed of.

Key Benefits of GN’s Oily Sludge Treatment System

• Resource Recovery: The oil recovered from the sludge can be used as a valuable resource, reducing waste and promoting sustainability.
• Water Reuse: The system allows for the reuse of washing water, making it an environmentally friendly solution.
• Efficient Sludge Disposal: The system significantly reduces the oil content in sludge, enabling further treatment such as biodegradation, thermal analysis, or incineration.
