Solids control decanter centrifuge detail

XI'AN, China - June 16, 2016 - PRLog -- Solids control decanter centrifuge is 5^th phase purification equipment for oilfield drilling fluid process.

Decanter centrifuge separation

Decanter centrifuge operates mainly by sedimentation , a process causing the separation of suspended solids by virtue of their higher density than the liquid in which thy are suspended. If the density difference is high, then gravity may provide sufficient driving force for the separation to occur in a reasonable time - as is the case with large-tank clarifiers and clariflcculators, or with lamella and inclined-plate separators. If the difference in density is small, or the prticle size is very small, then the gravity separation would take too long, and the separation force must be augmented by the imposition of centrifugal forces many times that of gravity alone

The centrifugal force may be imposed by virtue of the flow of the slurry, as in a hydrocyclone, or by means of mechanically driven rotation, as in the sedimenting centrifuge

Different types of solid sedimenting decanting centrifuge, including:

The tubular bowl centrifuge, mainly used for liquid/liquid separation, for which use any suspended solids would require cessation of operation for their removal (the tubular bowl centrifuge is also used for very difficult solid/liquid separations, where there is a low concentration of solids, which cannot be flocculated);

The imperforate basket centrifuge, which is operated batch-wise for the removal of collected solids;

The disc-stack centrifuge, originally developed for liquid/liquid separation

The decanter

Decanter centrifuges application

Solids control decanter centrifuge, such type centrifuges can be also used for most types of liquid/solid separation, and its ability to handle a wide range of feed slurry concentrations adds to its general versatility

It can be used for the classification of solids in liquid suspension, where a single cut is required between two sizes of solid particle. It is a very good device for this purpose and its early history included development for the kaolin industry.

It can also be used in the recovery of a valuable solid from its suspension in a liquid, and following such recovery it is capable of washing the recovered solid free of the original mother liquor, and of deliquoring (dewatering) the washed solids to a high degree of dryness

The decanter centrifuge can be used so as to act as a thickener, producing a clear liquid and a more concentrated slurry - either in a manufacturing process or in waste treatment

Solids control decanter centrifuge is popular with almost contractors since the great performance and wide range application for whole oilfield project. You can find more detail in former press and future press. Please give pay more attention on our release center
