The detailed description of the oilfield sludge decanter centrifuge

The oilfield sludge decanter centrifuge belongs to a separation device. Analyzing from the  theory , the ability of separating solid particles from liquid mixing slurry by the oilfield sludge decanter centrifuge mainly depends on the characteristics of imported mixed slurry. Therefore, in practical application, the processing efficiency of the equipment is often affected by the particle size and density of solid particles, and the density and particle size of the liquid phase.

 

Usually, if the particle size and density of solid particles are relatively large, and the density and viscosity of the liquid phase are relatively small, the separation capacity of the oilfield sludge decanter centrifuge is relatively large. In addition, the shape and porosity of the particles will have different effects on the separation effect. In general, variables affecting the performance of the centrifuge are mainly included: Sedimentation time, centrifugal force, torque characteristics, and inlet mud flow.

 

With the improvement of the technical level, the current oilfield sludge decanter centrifuge can realize the continuous automatic separation operation. During the operation, first, the sludge in the sludge tank is transported to the  measuring tank, and after the adjustment, the sludge quantity will be adjusted appropriately. The remaining sludge is returned to the sludge tank through the reflux line. In addition, the sludge and flocculant are usually added in the flocculation mixing tank and stirred.

 

With the operation of the oilfield sludge decanter centrifuge, the sludge after being concentrated will move forward with the running direction of the spiral shaft, and fully dehydrated under the internal pressure of the back plate. The mud cake after dewatering is discharged from the gap between the back plate and the spiral body.

 

In a word, the oilfield sludge decanter centrifuge has achieved good application effect in the actual work. Especially with the improvement of the technical level, the new generation of oilfield sludge decanter centrifuge has a further improvement in the wear resistance and efficiency, which has brought great help to the drilling mud separation operation.
