Centrifuges in the drilling solids control system and mud zero discharge system

The centrifuge is a common equipment in the drilling solids control system and the mud zero discharge system, so what is the difference between the centrifuges in the drilling solids control system and the mud zero discharge system?

Centrifuges in Drilling Solids Control Systems

The centrifuge in the drilling solids control system generally adopts medium and low speed centrifuges. Since the drilling solids control system adopts multi-stage solids control equipment, when the drilling fluid is filtered and separated from the mud shaker to the true remover to the sand and mud integrated machine after three-stage filtration and separation, the particle size of the mud particles has become very small, and the configuration requirements of the centrifuge have become smaller. Medium and low speed centrifuges have been able to meet the needs of slurry pulping.

Centrifuge in Mud Zero Discharge System

The centrifuge in Mud Zero Discharge System generally adopts a high-speed centrifuge or a frequency conversion centrifuge, which is a high-end centrifuge. The Mud Zero Discharge System is composed of a drill cuttings dryer and a high-speed variable frequency centrifuge. The Mud Zero Discharge System is located at the end of the solids control system and is used to process the drilling cuttings tailings processed by the solids control system, so the proportion of drilling cuttings tailings is very large, the solid particle size is large; because the centrifuge is to undertake the mud processed by the drilling cuttings dryer, the particle size in the mud screened by the drilling cuttings dryer is very large, and the requirements for the centrifuge are very high. Therefore, it is more appropriate to use a high-speed variable frequency centrifuge.

The pump sucks the sludge from the suction pipe, and the sludge discharge pipe discharges the sludge to the river bank or directly into the mud barge for transportation to a certain place for temporary storage and then for sludge dewatering treatment. The cutter suction boat is mainly aimed at the bottom of the river where the sludge is soft in the river channel.

4) Screw stacker sludge dewatering equipment: The working principle of this equipment is that after the sludge is first concentrated by gravity, the screw stacker is transported to the dewatering section, and gradually becomes smaller with the filter seam and screw pitch during the working process. , and the great internal pressure generated by the resistance of the pressing plate, the capacity is continuously reduced, thus truly realizing the purpose of dehydration. The screw stacker has a wide range of applications and is suitable for the advantages of high and low concentration sludge dewatering.

5) Decanter centrifuge sludge dewatering equipment: The process flow of the dewatering equipment can be roughly divided into: the pump lifts the sludge and then performs a screening pretreatment system, and then adds an appropriate amount of flocculant to the sludge to fully stir, and finally uses Centrifuges perform deep dehydration procedures. The dry and solid mud cake after sludge dewatering can be transported to other places where it needs to be reused, which truly achieves the double harvest of environmental protection, energy saving and economic value. The advantages of this equipment are convenient and simple operation, large processing energy, small processing site occupation, high degree of automation, and low noise due to low vibration.

6) Diaphragm filter press sludge dewatering equipment: The sludge dewatering process of this equipment can be roughly divided into: the sludge lifted by the pump enters the primary sedimentation tank and the secondary sedimentation tank, and then continues to enter the grid and concentration tank Then, a certain amount of flocculant is added for complete stirring and mixing, and then it enters the homogenization tank. Finally, it is highly dehydrated by the filter press, and the treated filter cake realizes the resource utilization of external transportation. The advantages of diaphragm filter press are high compression pressure, large processing capacity, low moisture content of filter cake, stable equipment performance, low failure rate and high degree of automation.

7).Geotechnical pipe belt sludge dewatering equipment: The process flow is roughly as follows: first, the sludge is filled into the geotechnical pipe belt for many times through a mud pump, and an appropriate amount of flocculant is added to promote the solid-liquid dewatering effect of the sludge. The combination of the filter part of the pipe bag and the two power factors of the liquid pressure will quickly and efficiently dehydrate the added dewatering agent sludge, and the solid part of the dewatered sludge will be trapped in the geotechnical pipe belt, and the percolating water will be discharged to the river after treatment. in the waterway or directly into the municipal sewage pipe. The solid portion trapped in the pipe can be reused in other industries for efficient resource utilization. Its advantages are good anti-wear performance, good UV resistance and water permeability. The geotechnical tube bag has a strong accommodation capacity for sludge, a large volume adjustment range, and a civilized and hygienic working environment. It is suitable for projects with large amount of sludge dewatering, large construction site and relatively loose construction period.
