Hydrocylone working principle from Eric Tian.

Hydrocylone separators (desander, desilter and mud cleaner) are at work on more drilling rigs around the world. Removing cuttings from drilling mud those hard abrasive particles too small to be rejected by a shale shaker or settling tank. Together Desanders and Desilters remove over 95% of any solids down to 10 microns and size. Smaller than official solids such as collides clay and other small solids are retained in the mud system to ensure suitable wall building characteristics in the borehole. Typical separators are as tough as the equipment they help protect. Mud valves, slurry pumps, manifolds swivels and drill pipe they&#;re precision engineered to effectively maintain and improve drilling hydraulics by reducing mud weight. They&#;re efficient and economical helping speed drilling rates reducing the need for water dilution and replenishment extending the life of drill pits.

The heart of the Desander, desilter and mud cleaner are the cyclonic cone (Polyurethane hydrocyclone), ranging from 4-inch to desilter&#;s up to 12-inch desanders. Drilling fluid under pressure is directed into the cone through the tangential inlet. Rotary movement is created when the fluid strikes the curved inner wall of the cone. This sets up a centrifugal force which separates the fluid into conical layers. The heavier particles are forced to the cone wall and move downward by gravity. As the cone tapers the solids gain speed and separation efficiency increases. These solids are then discharged at the bottom of the cone through this underflow outlet or apex. Meanwhile the lighter fluid now mostly free of solids floats to a vortex or vacuum formed at the center of the cone and is drawn upward through an overflow outlet. Fluids are then returned to the mud system to be reused and the cycle starts again. A hydrocylone is a remarkably simple thing. There are no moving parts and in this 4-inch style desilter only six basic parts make up the completely assemble cone. Maintenance and repair are limited almost entirely to occasional replacement of the protective cone liners.

You&#;ll notice here near the bottom of the cone. These tattletale warning holes liner wear is more concentrated at these points. Fluid seepage allows you to visually check for liner wear without taking the cone apart. With the few exceptions which will point out, the same basic component parts are used in all Desander and desilter cones. This style each cone is the one you&#;ll find most often in the desilting operation. It&#;s longer length increases fluid retention time thereby increasing separation efficiency.

Following is desander for two different industry and system, Part 1 two desanders are for oil gas drilling, CBM drilling mud solids control. Part 2 desander system with mud tank is for contruction operation for No dig, Bored Pile drilling deander for bentonite recycling.

Part 1: Desander for Oil Gas drilling & HDD

GN desander is the second class and the third class solid control equipment to treat the drilling fluid. According to the size of the cone diameter, it is divided into Desander and Desilter. Usually the cone diameter is more than 6&#;is called Desander, and used as the second-control equipment in drilling operation. We commonly used 8 "and 10" cones desander to separate solid-phase particle size 47-76μm in the drilling fluids

GN Mini Mud Cleaner(Desander)

The GN Mini Mud Cleaner is innovative products for drilling fluids cleaning. The traditional desander desitler without Shale Shaker is only available for unweighted drilling mud.The traditional mud cleaner is oversized for some applications,and the mud cleaner is relatively more expensive. The innovative GN Mini cleaner is an ideal option for both weighted and unweighted drilling mud with the most cost effective solution for drilling. Further more, the GN Mini Cleaner is the best choices for small mud system for HDD,CBM, water well drilling, mining exploration industry etc.

Desander for Oil drilling mud

Hydrocyclones is also called cyclone separator.Hydrocyclones consist of desander(10 in. cone) and desilter(4 in. cone)are drilling rig equipments with a set of hydrocyclones that separates sand and silt from the drilling fluid. Desander is installed after shakers and degasser but before desilter. Desander removes those abrassive solids from the drilling mud which cannot be removed by shakers.

Desander, as stated earlier, have no moving parts. The larger the internal diameter (ID) of the desander is, the greater the amount of fluid it is able to process and the larger the size of the solids removed. Desander (10 in.cone) are able to remove roughly 50 percent of those solids within the 40-50 micron range at a flow rate of 500 gallons per min (gal/min), while desilter (4 in. Cone) are able to remove approximately 50 percent of those solids within the 15-20 micron range at a flow rate of 60 gal/min. Micro fine separators are able to remove around 50 percent of those solids within the 10-15 micron range at a flow rate of 15 gal/min. Desander is typically positioned next-to-last in the arrangement of solids control equipment, with decanting centrifuge as the subsequent processing unit. Desander are preceded by gas busters, gumbo removal equipment (if utilized), shale shakers, mud cleaner (if utilized) and vacuum degasser.Desander is widely used in oilfield drilling.

Bored piles are cast in place cylindrical piles excavated either by use of rotary equipment operated augers , buckets, under static drilling fluid or large drill bit (for hard rock) with reverse circulation.The reason to use desander unit is that Bored piles installed in common soil with the presence of water table, generally require the use of a short temporary steel casing and a drilling fluid as static suspension to provide support to the surrounding soil while excavating the pile and until complete backfill of the pile excavation with concrete, in order to prevent cave-in of the excavation and destabilizing the surrounding soil formation.GN Bored Pile desander is to separate the sands from the drilling fluids and recycling the drilling fluids for use.
