Full Hydraulic Drive (FHD) Decanter Centrifuge for drilling mud treatment

BY admin 12 June 2020 Decanter Centrifuge, Drilling equipments Company, drilling mud centrifuge, Drilling Waste Management, solids control, Solids Control Equipments

GNLW363 FHD centrifuge is a Full Hydraulic Drive decanter centrifuge. It is designed to remove low specific gravity solids from slurries. After the FHD centrifuge separation, the solids are removed and the liquid is returned for recirculation. Like in the drilling mud system, the recovered slurry is drilling fluids, it can be reused in drilling mud system, in waste water treatment system, the recovered slurry is water, which can be reused in the waste water treatment plant. And in some cases, like in the barite recovery treatment, the solids are returned to the active system and the liquid is discarded, or goes to further treatment processing.

GNLW363C-FHD decanter centrifuge is fully hydraulic drive. Th Full hydraulic driven system is imported from leading brand from Switzerland. The bowl speed and conveyer speed of GN FHD decanter centrifuge is adjustable within the permitted range. It can achieve independent, step-less and large-range speed regulation for the bowl and conveying. The bowl speed and conveyer speed during working is showing on the screen.

The advantage of the full hydraulic drive centrifuge is for use in high temperature ambient for heavy mud with flexible bowl and differential speed. The compact one skid design makes it easier for rig up.

GN FHD decanter centrifuge is composed of bowl assembly, collection box, hydraulic drive system, electrical control panel, drive motor, vibration switch (optional), case, base assembly, and skid.

During decanter centrifuge operation, drilling mud or slurry is pumped through the feed tube into the center of the rotating conveyor, where it splashes against the feed accelerator. Screw pump is widely used as feeding pump for decanter centrifuge, besides screw pump, centrifugal pump and submers. The high velocity slurry is then dispersed out four feed nozzles mounted in the periphery of the conveyor cylinder. Rotating at a higher speed than the conveyor, the bowl creates an additional shearing effect, which further increases the slurry’s acceleration. The depth of the slurry in the bowl (pond depth) is determined by the setting of weirs on the liquid bowl head (large end of the bowl).

Oil Sludge Treatment Plant for Environmental Solutions Company

This week, a full package of compact oily sludge separation system was finished from GN factory in Beijing China. The compact design fast movable oily sludge treatment system is purchased by a reputable Environmental Solutions Company from China domestic market.

There are 3-stage separation equipment included in the oily sludge treatment system.

1) There is a 2-panel small footprint shale shaker equipped in the system for coarse solids separation. The model is GNZS752. As mostly, the oily waste come out from different sources and it is mixture of different wastes. There may be big size solids in side. The big sides solids may block or even broken the centrifuges. The small size shale shaker is used to remove the possible big size solids in the sludge.

2) There are 2 centrifuges in the oily sludge treatment system. The first centrifuge we call it decanter centrifuge. The decanter centrifuge model is GNLW224, it is a 2-phase separation centrifuge. The 2-phase decanter centrifuge is help to remove solids or soil from liquid mixture. The 9 inch centrifuge is a min size decanter centrifuge. The bowl diameter is only 9 inch, but the bowl length and diameter ration is up to 4. The longer ration can help to get cleaner liquid. It is the smallest centrifuge from GN Solids Control for industry separation.

3) The second centrifuge inside the oily sludge treatment system is disc centrifuge. It is also called 3-phase centrifuge. As the name mean, the disc centrifuge can separation oil, water and soil.

Many people may wonder: in case the disc centrifuge can separate and get oil, water and soil. While you add 2-phase decanter centrifuge inside the system? Really, the 2-phase decanter centrifuge is surely not to increase the cost. The disc centrifuge can only allow liquid mixture with liquid content less than 3%. Otherwise, it will damage the centrifuge. While the decanter centrifuge can allow liquid with solids content up to 15% ~ 20%. Decanter centrifuge is a necessary as pre-separation before disc centrifuge.
