Industry Information about Decanter centrifuges for sale

Decanter centrifuges for sale utilize centrifugal force to speed the dewatering or thickening of slurries and suspensions in many industrial and commercial applications. While these centrifuges, like others, may also be used to separate liquids from liquids, they are more applicable in situations that require the separation of liquids from appreciable amounts of suspended solids.

Food and beverage, water treatment, oil, gas and pharmaceutical industries commonly employ decanter centrifuges for the classification of solids based on the sedimentation principle as well as the clarification of fluids resulting from the settling out of debris. Other industrial uses for decantation include solids recovery which enables many manufacturing facilities to recover and reuse valuable materials that would otherwise be disposed of along with wastewater.

While gravity alone is sometimes used, decanter centrifuges are essential in applications where the density difference of elements within a heterogeneous mixture is too small or the particles themselves are too small. Whereas normal gravity could take ages to sort these materials, the centrifugal force generated by industrial centrifuges speeds the process while producing drier solids. Dryness is important as both dewatering and drying materials helps to provide raw or processed substances that are lighter in weight than their immersed counterparts making for easier handling and lower transportation costs.

The operation of a decanter centrifuge can be either batch or continuous and is not altogether dissimilar to other types of centrifuges. A metal or plastic cylinder fixed along a central axis houses the materials or solutions to be sorted. When a motor engages the axis perpendicular to this, it creates a rotational movement capable of creating gravitational pulls up to twenty thousand times that of normal gravity. This causes larger particles to separate out first in a radial direction allowing them to move toward the bottom of the cylinder while lighter materials move toward the top.

In some decanter centrifuges a mesh is used to collect solids with liquids passing through to the outer area of the cylinder before being drained. In other models a helical extraction screw directs solids to one end and liquids to the other. If high enough acceleration is reached, the solids may even become compressed for easy removal. Both new and used centrifuges are available to purchase. As adjustable and fixed acceleration models are widely available, it is important to consider the parameters of a specific application before purchasing a decanter centrifuge. Capacity should also be considered with regard to the intended use as should the design and material construct of a decanter centrifuge as these materials must be compatible with both process liquids and solids to be sorted.

Summary of Effective Solids Control system

The state of the art solids control system includes improved versions of this original equipment, first introduce into the oil industry many years ago. Although much more efficient and robust the core technology has change little over the past few decades.

Theory of  Solids Control system:Drilling fluid and equipment maintenance cost can decrease greatly when proper solids control practices are utilized. From a fluid control stand point it would be desirable in most cases to remove all drilled solids. Although this is possible, it would be cost prohibitive. The goal of a solids control system is to achieve the balance between mechanical solids separation and dilution that will result in drill solids being maintained at an acceptable level with a minimum of cost.

Summary of  Effective Solids Control system:

1.Obtain solids removal equipment for your operation.

2.Remove as many drilled cuttings as possible before being pumped back down the bore hole.

3.Do not by pass the shale shaker or other solid control equipment while drilling.

4.Use the smallest mesh screen possible on the shale shaker.This will change from formation to formation.

5.Maintain an adequate inventory of recommended spare parts.

6.Train & assign rig personnel to be responsible for equipment operation & maintenance.

The continuing trend of more stringent environmental regulations around the world will require more and more solids control system to be implemented to minimize haul off of drilling waste not to mention the cost saving on equipment such as mud pumps and mud motors.

The future path of solids control system will continue to increase the overall removal efficiency of undesirable solids from the drilling mud. This will include continued improvements in shale shakers and screen life. Research investigating alternate technology such as using vacuum techniques and different motions may prove more effective in the future. (Editor:Kosun Lily.Wang)

Solids Control Equipment-KOSUN Solids Control system

-Shale Shakers:the first line of defense for a properly designed solids control equipment has been and will continue to be, the shale shaker. Without proper screening of the drilling fluid during this initial removal step, reduced efficiency and effectiveness of all downstream solids control equipment in the system is assured. The downstream hydrocyclones will simply be overloaded beyond their designed capacity.The shale shaker, in various forums has played a prominent role in solids control systems for several decades. The two main shale shakers utilized in the utility industry are:1.Elliptical, “unbalanced” design;2.Linear “straight line” design.

shale shaker

Vibrating Mechanism-the purpose of vibrating the screen in solids control equipment is to tumble the solids particles to separate fluids from solids and increase through put capacity. This vibrating action causes rapid separation of whole mud from the oversize solids, reducing the amount of mud lost with the solids.

For maximum efficiency, the solids on the screen surface must travel in a predetermined pattern. For example; some devices use elliptical motion and others use Linear motion to increase efficiency. The combined effect of the screen and vibration, result in the separation and removal of oversized particles from drilling mud.

Hydrocyclones-Hydrocyclones have become important in solids control equipment because of their ability to efficiently remove particles smaller than the finest mesh screens. They are also uncomplicated devices, which make them easy to use and maintain.

A hydrocyclone consist of a conical shell with a small opening at the bottom for the underflow discharge, a larger opening at the top for liquid discharge through an internal“vortex finder”and a feed nozzle on the side of the body near the wide (top) end of the cone.

Desanders-Desanders are hydrocyclones larger in diameter than 5”.  Desanders are installed down stream from the shale shaker. The desander removes sand size particles and larger drilled solids, which have passed through the shale shaker screens. These solids are discarded along with some liquid into the waste pit. The clean mud is then discharged into the next pit ready to be run through the desilters.

Desilters- A desilter uses smaller hydrocyclones usually 5” or smaller. The smaller cones enable desilters to make the finest particle size separation of any full flow solids control equipment. Removing particles of 15 microns and larger. Multiple cones are normally used in this application to obtain the required GPM you need for your solids control equipment.

Mud Tank Separation-There are many ways to configure your mud tanks below your solids control equipment. The most common practice requires three sections. Under your shale shaker you have the first section known as the sand trap where the mud to be pumped from this section goes through your Desander. This cleaned mud is then dumped into the second section known as a silt tank. The mud is picked up then pumped through your Desilters. The Desilters dumps the cleaned mud into the third section, know as the clean mud or mixing tank. This will be picked up by  the pump to be pumped back into your bore hole.

Centrifugal Pumps-Another important aspect of a well engineered solids control equipment  is the use of centrifugal pumps which not only mix the mud to be pumped down the bore hole, but also provide the feed pressure and volume required to operate the hydrocyclones. Maintenance of these pumps is essential to the operation of your solids control equipment. (Editor:Kosun Lily.Wang)http://solid-control.com

Features of KOSUN Decanter Centrifuge for sale

Solids control equipment decanter centrifuge is one stage of solids control system.Normally solid control system is consist of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, decanter centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as Hi-volume mud cleaner. When air enters into the drilling fluids, vacuum degasser is used to separate the air. If no air in the mud, the degasser would work as a big agitator. All these equipments are mounted on the top of the mud tank. Decanter centrifuge is used in separating suspension of solid phase with particle diameter d>=2um for drilling mud and fluids handing.
