KOSUN DC Series Decanting Centrifuge Separation Principle

Decanting Centrifuge Separation Principle:Taking advantage of the principle that the light liquid, heavy liquid and solid phase, with different density and mutually insoluble in the mixed liquid, gain different sedimentation speed in the centrifugal force field or gravity force field, separating stratification or causing the solid particles in the liquid to deposit can be achieved.

KOSUN DC series decanting centrifuge is used in separating suspension of solids phase with particle diameter(d≥2μm) for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The centrifuge must test the dynamic balance for smooth operation over long periods.Speed ranging from 0 to 3900 RPM, generating centrifugal forces reach up to 3000G.

DC decanting centrifuge is ideal choices for separating particles in drilling mud. Decanting Centrifuge separate the suspending fluids using  the principle of centrifugal action, the suspending fluids is pushed into the rotor drum through the inlet pipe and the fluid hole of the spiral feeder. Under the influence of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the mud export of the small end of the drum and excreted. But the fluids is excreted from the overflow hole of the large end. Such cycle is in order to achieve the purpose of continuous separation.High speed decanting centrifuge are effective for separation

Decanter Centrifuge Safety Operation Regulation Tips

In the whole markets, centrifuge or even decanter centrifuge has been used in most fields. There are also mutual types or styles of decanter centrifuge in different fields. We just take oil drilling industry as an example,there are RFD decanter centrifuge, VFD decanter centrifuge, Disc centrifuge, hydraulic centrifuge, etc.

Now KOSUN want to share some necessary tips about safety operation regulation for decanter centrifuge. The following content is about the topic of “6 Tips of Safety Operation Regulation for Decanter Centrifuge”.

Decanter Centrifuge
Decanter Centrifuge

Just as we all know that Decanter Centrifuge is one kind of machine revolving at high speed. During operation, revolving drum will generate strong centrifugal force (it is not like the solid control system, to some extent, decanter centrifuge is a core part for a whole solid control system and water based mud unit). To ensure the safety of operators and equipment, the following safety rules shall be strictly followed when using it.

  1. Pay more attention for original Instruction Orders or Steps. Through dynamic balance of revolving drum parts of centrifuge, during assembly, original installation order shall not be changed and there shall be no parts omitted. Threaded connection part shall be installed in place; during assembly, if there is assembly mark, the mark shall be aligned. Before startup, operating pump system shall be inspected and there shall be no water leakage under close state of magnetic valve.
  2. Keep the decanter centrifuge off. Before clamping revolving drum clamp ring and fixing inlet/outlet device and other fastening screws, decanter centrifuge shall not be started.
  3. Before completely stopping revolving drum, any part of equipment shall not be loosened.
  4. During operation, if abnormal vibration of decanter centrifuge is found, power shall be cut off for emergency shutdown. After revolving drum is completely stopped, each part shall be disassembled cleaned and inspected and attention shall be paid to assembly order and position. After the causes of abnormal vibration are found out and removed, reassembly and startup can be carried out. Time interval between re-startup and shutdown shall be more than 4h (This item is also suitable for mud cleaner).
  5. Flame heating or repair welding of main revolving drum parts is not allowed, especially revolving drum body, revolving drum cover and clamp ring.
  6. Use of revolving drum parts and revolving drum parts of other equipment shall not be mixed, even the revolving drum parts with same model.

The above 6 tips or we can call it as steps should be kept in our mind, they can help us improve our working efficiency. Just as I mentioned in the post, you could find more information about solids control system, drilling waste management unit, oil recovery unit, and some other solids control equipment, such as mud cleaner, sand pump, vacuum degasser, cutting dryer, etc. In another words, KOSUN could be your better cooperator.

Operating and maintaining process of decanter centrifuge

decanter centrifuge is a very useful equipment for any drilling site. A decanter centrifuge is basically used to dilute the fluid that is extracted from the gas or oil mine. Generally, the liquid that is extracted from a mine is of highly concentrated and coagulated. So, extracting minerals from them is practically impossible.  In order to thin up the extracted fluids, a decanter centrifuge is used. By using the rotational speed of a decanter centrifuge, the highly concentrated are turned into minerals extractable thin liquid.

Decanter Centrifuge

There are three basic designs of decanter centrifuges. The first one is vertically oriented decanter centrifuge, the second one is horizontally oriented decanter centrifuge and finally the third one is conveyor or scroll decanter centrifuge. In the vertically oriented decanter centrifuges, the fluids or solids are gathered vertically.

Vertical decanter centrifuge is very effective for high temperature and high pressure work. A horizontally oriented decanter centrifuge gathers the fluids or solids generated from high rotation in horizontal orientation. A horizontally oriented decanter is very effective for high pressure works as it provides a strong organization due to its horizontal orientation. Lastly, a conveyor or scroll centrifuge is basically a rotating machine inside a bowl.

The operating and maintaining process of a decanter centrifuge:

The first thing that should be done to maintain a decanter centrifuge is to replace any hydraulic suction filter and replace hydraulic returns filter. It is a very important step for the oil and gas drillers. As when the oil or gas drilling goes on both the hydraulic suction filter and the hydraulic returns filter undergo an extensive pressure.  So, there is a huge possibility of both of them to be worn out. So in that sense, both of the filters must be checked regularly and be replaced when it is necessary.

Another important thing that is required to do in order to maintain a decanter centrifuge is greasing the machine.  It is very important. As decanter centrifuge is basically used in a heavy working areas, the machine can easily be stuck or jammed off. In order to avoid that, greasing is very important. Oil lubricated gear box greasing and recirculating oil greasing are two very effective methods for greasing. A very significant task for managing a decanter centrifuge is adjusting speed sensor to it. It is very important just because adjusting a speed sensor enables drillers to control the differential speed.

Beside these above mentioned activities replacing hydraulic motor sensor, bowl belt replacement, scroll belt replacement and regulating the weir plate are some of the steps that should be taken to maintain a decanter centrifuge. (Editor:Kosun Lily.Wang)

The Operation of a Decanter Centrifuge

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.

Decanter Centrifuge

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.

Decanter centrifuges 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.(Editor:Kosun Lily.Wang)

Brief description of Decanter Centrifuge

A decanter centrifuge is a device that can create a very fast rotation. A decanter centrifuge is basically used to dilute the fluid that is extracted from the gas or oil mine. Generally, the liquid that is extracted from a mine is of highly concentrated and coagulated. So, extracting minerals from them is practically impossible.  In order to thin up the extracted fluids. By using the rotational speed of a decanter centrifuge, the highly concentrated are turned into minerals extractable thin liquid. There are three basic designs of decanter centrifuges.

Decanter Centrifuge

The first one is vertically oriented decanter centrifuge, the second one is horizontally oriented decanter centrifuge and finally the third one is conveyor or scroll decanter centrifuge. In the vertically oriented decanter centrifuges, the fluids or solids are gathered vertically. Vertical decanter centrifuge isvery effective for high temperature and high pressure work. A horizontally oriented decanter centrifuge gathers the fluids or solids generated from high rotation in horizontal orientation. A horizontally oriented decanter is very effective for high pressure works as it provides a strong organization due to its horizontal orientation. Lastly, a conveyor or scroll centrifuge is basically a rotating machine inside a bowl.

How does a decanter centrifuge work?

As it is mentioned before the process of a decanter centrifuge is a bit complex. Usually, a decanter centrifuge depends on sedimentation, differential speed and G force to perform its job. The sedimentation rate is an important feature for the centrifugal process. If the G force or centrifugal force is very high, the separation process becomes very easy and effective. The size and shape of particles and their level of concentration determine the sedimentation rate of any decanter centrifuge. The sedimentation rate also depends on the centrifugal force.

Another important issue for the functionality of a decanter centrifuge is the differential speeds. In a centrifuge two different parts rotate simultaneously. The first part that rotates is the exterior bowl and the second part that rotates is scroll conveyor. Sedimentation is gathered in the centrifugal cylinder as the result of varying speed of the two above mentioned separate parts. If the differential speed of a decanter centrifuge is too high, a little time is required to loosen up the concentration of waste fluids. So, it is very important to keep the differential speed of a decanter centrifuge minimal. Thus, a decanter centrifuge operates its functionalities. (Editor:Kosun Lily.Wang)

Decanter Centrifuge Working Principle of Kosun Solids Control System

Decanter Centrifuge

Decanter centrifuge of drilling waste is the waste matter generated as a result of the very process of extraction of oil and gas from the earth, popularly known as drilling. This is an extensive and trillion dollar industry with a corresponding and gigantic waste production issue on a global scale. That is why; a new drilling waste management system called drilling waste management was introduced.

Decanter Centrifuge
Decanter Centrifuge

It consists of a series of processes from collection, management and containment of waste to subsequent treatment and disposal. Over the years, many techniques and methods were introduced for an efficient management of drilling waste. Also quite recently we saw more advancement and mechanization being brought into the whole process.

As a result of this, now we have instruments like decanter centrifuge to aid to the separation and handling of drilling waste. So let’s understand more about them and their mode of operation.

As the name suggest, the equipment uses decanter centrifuge forces to aid to the separation of desired and waste matters taking advantage of their differences in densities and other properties.

The mixed substance obtained from extraction is made to enter a disc or cone shaped structure that is rotated at a suitable speed. Because of the difference in natures of the unwanted and desired quantities, they are separated by combined effect of centrifugal and gravitational forces.

The fuel which is separated drops through the hole at the centre of the structure and the waste remaining in it is properly contained. For better gathering or collection of these waste matters, the walls of the discs are generally made with interspaces or slot like cavities.

The drilling waste progresses towards the walls of the disc and moves into a containment tank through the interspaces provided. As the machine consists of several moving parts, all components are to be kept smooth and clean to ensure optimum efficiency.
