10" Polyurethane Drilling Fluid Desander 45um For Mud Circulating System

10" Polyurethane Drilling Fluid Desander Cyclone Separate 45um-75um Particles For Mud Circulating System

Working principle of drilling fluid desander

The drilling mud is transported to the desander cyclone by the centrifugal pump in the shale shaker tank. Under the pressure of the centrifugal pump and the impact force of the mud flow, the drilling mud forms vortexes in the cyclone and the solids in the drilling fluid settle to the bottom of the cyclone under the action of centrifugal force and gravity, and finally ejected out through the nozzle.The solid particles are further screened and filtered in the bottom flow screen.The lighter, clean liquid will flow directly into the desander tank through the discharge lines of the cyclone cluster.The liquid in the desander tank will be supplied to the desilter pump for the third stage solid control treatment

Technical specification for your reference.

Application of drilling fluid sand desander

Secondary solid control treatment of mud and fluid to be treated in oil and gas drilling, coal bed methane excavation, trenchless directional crossing, pile driving, waste sewage, mud treatment, etc.In short, it is suitable for a variety of environments of mud and solid liquid mixture desanding treatment.The general excluded particle size is bigger than 45 microns.

Structure components of drilling fluid desander

It mainly includes base, frame, motor, control cabinet, cyclone group, corresponding pipeline, shale shaker screen, fixed screen device. Some customers require that the desander should not be equipped with a bottom flow shale shaker and only require a desander without downstream shale shaker, such structural components do not include the motor, control cabinet , shale shaker screen and fixed screen device.

For oil drilling mud process, desander cone is sized 8-12''. Different size cones hold different treating capacity. Before we confirm the configuration or design on mud desander, we should consider the flow rate of all cones. For example, 10" cone capacity is about 90-120m³/h and we request 240m³/h flow rate then we need 2 desander cones at least.

Cones on APCS Desanders are all high quality polyurethane. Such cones are durable and anti-corrosive, oil-resistant, high temperature-resistant. They are very suitable for drilling fluids process. For some clients, they prefer flexible capacity adjustment during operation so we'll install ball valves on the cones inlet line. And we can configure 3 desander cone sized 10'', or 2 desander cons sized 12''. For much larger capacity, we can use 3 desander cone sized 12''. Moreover, some clients prefer the casting iron desander cone. According to the actual demand and condition, we'll make desander to satisfy both clients and working condition.

For desander separator, the bottom shaker is a flexible configuration, too. It can be Hunter-D series, or Hunter-M, or Hunter-Mini. And the screen panels can be 2, 3, or 4, even 5. For some clients' preference on dual motion, it can be made as dual motion desander, too.

Actually, the bottom shaker under desander cone is used to dry fluids out of cone. So, the mesh size is rather high and the capacity is enough for discharge from cone but not same as previous shaker

Safe operation of drilling fluid desander

Before using the equipment, make sure the pressure gauge reading is within the safe range.Before use, confirm the seal status of inlet/outlet and manifold connections.
Maintenance of drilling fluid desander:
1. In the process of use, pay attention to check whether the pressure gauge is normal;
2. Sealing inspection should also be done at the inlet and outlet and manifold joints;
3. If there is a bottom flow screen to pay attention to the use of the state of the screen and wear degree;
4. Pay attention to cleaning to ensure the service life of equipment

Matters needing attention for drilling fluid desander

1. When you feel that the force of the liquid sprayed by the trickle nozzle of the cyclone is not enough, please check whether the equipment has leaked parts or whether the pressure is sufficient;
2. If the efficiency of desander is reduced, it may also be that the flow of slurry pump is not enough, please consider adjusting the pump set;
3. The desander does not pulp out, which may be blocked by the drip nozzle. Please unscrew the drip nozzle cover and dredge it, then it can be restored to normal;

If there are any other problems, please refer to the troubleshooting part of the manual to solve them or contact Aipu to settle for you.
