Decanter centrifuges-the preferred equipment for foreign sludge treatment

Industry experts pointed out that with the massive construction of large-scale municipal sewage treatment plants in our country, decanter centrifuges are increasingly used in the municipal sludge dewatering field, leading to some foreign brands one after another pouring into the Chinese market. Some domestic manufacturers also use cheaper Price into the market.

Although imported decanter centrifuge price is 2 to 3 times than the domestic price, the imported decanter centrifuge still occupy a larger market share. In the area of sludge dewatering in industrial and municipal wastewater treatment, especially in some newly-built municipal sewage treatment plants, almost all of them are used the imported decanter centrifuges.

Undeniably, the centrifuge industry first developed in foreign countries, the early core technologies are also in foreign countries, decanter centrifuge has also become the preferred foreign sewage sludge treatment equipment. Despite its late start, our country has also experienced more than 20 years of hard work. Through cooperation with foreign countries and its own research and design, the domestic centrifuge technology has been almost mature, and began to compete with foreign countries in high-end decanter centrifuges .

Therefore, the decanter centrifuge in the field of urgent need to break the dependence on imports, learning more advanced foreign technology, innovation, research and development for China’s pharmaceutical industry needs decanter centrifuge, centrifuge equipment to slowly withdraw from the Chinese market To achieve self-sufficiency.

Mr. Fang Bochun, general manager of Jiangsu Environmental Protection Equipment Co., Ltd., said: “In the next five years, the centrifuge industry will usher in tremendous changes. Enterprises should step up research and development capabilities and put new centrifuge design concepts into production as early as possible. Many new centrifuges to market, so as to truly solve the separation requirements of large enterprises and provide effective solutions to enhance the international image of China’s centrifuge field. “(Editor:Kosun Lily.Wang)

Drilling Decanter Centrifuge Good Performance by Kosun

Drilling Decanter Centrifuge

Drilling Decanter centrifuge equipment is used to serve the purpose. The equipment uses the centrifugal force to separate different materials for treatment.

Wherever there is a need to separate materials of different densities is involved, There are many types of centrifuges, decanter centrifuges , vertical centrifuge etc.

Now building on this definition, we can imagine the vast application of such equipment in a variety of industrial scenarios, where different materials need to be separated. Let us pick oilfield drilling industry for an instance, where large volume of drilling waste is produced by the drilling process.

Not only the waste is harmful to the environment, if disposed directly without treatment, but it also contains large quantity of drilling fluid that needs to be extracted and restored. To accomplish this challenging task of separating the fluid, decanter centrifuges are deployed in drilling operations.

The working of a centrifuge could be understood as – If laid down in plain words – it uses the express rotation to separate different types of materials. In a more technical expression, a centrifuge is the equipment that uses the centrifugal force to separate substance based on their density using the principle of sedimentation.

Imagine a jar full of milk cream, when churned at good speed, it separates the cream into butter and skimmed milk. We know that different materials have different density, and the centrifugal force makes them move against the axis of the pit in which they are stored with the help of rapid rotations using mechanical force. Naturally the material with lowest density will make it way upward and the one with highest density will get settled at the bottom of the pit.

The decanter centrifuge equipment is used in a variety of machines that need to filter the mixture of solids and fluids. It finds it application in number of industries ranging from food processing industry to oil and natural gas industry.

How does Decanter Centrifuge Work?

Decanter Centrifuge

Introduction: Decanter centrifuge is a very common equipment that is often found in an oil or gas drilling site. A decanter centrifuge is a very important machine for oil and gas drillers. A decanter centrifuge is basically used to dilute the underground fluids and liquids.

The main job of a decanter centrifuge is to rotate the drilling fluids and in doing so breaking the concentration of those fluids. The whole working functions of any decanter centrifuges is pretty much complex. Here is a discussion given below about how a decanter centrifuge works.

The way a decanter centrifuge works: As it is mentioned before the process of a decanter centrifuge is a bit complex. Usually, decanter centrifuges depend on sedimentation, differential speed and G force to perform its job. A decanter centrifuge needs a centrifugal force in order to loosen the fluid.

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 decanter centrifuges 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 decanter centrifuges 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.

Decanter Centrifuge Defined Meaning

Decanter Centrifuge

Introduction: Modern gas and oil drilling sites are just a rigid manifestation of multi layered complex mechanism. Several gigantic equipments are set and operated in a single oil or gas drilling sites. The mechanisms of these equipments are very complex and very subtle. A very common equipment that is seen in an oil and gas drilling site is a decanter centrifuge.

A decanter centrifuge is a very useful equipment for any drilling site. Here in this article, we will try to provide a brief description about what a really it is.

A brief description of a decanter centrifuges: A decanter centrifuge is a device that can create a very fast rotation that 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.

There are three basic designs of decanter centrifuges:

The first one is vertically oriented decanter centrifuges.
The second one is horizontally oriented decanter centrifuges.
The third one is conveyor or scroll decanter centrifuges.

In the vertically oriented decanter centrifuges, the fluids or solids are gathered vertically. Vertical decanter centrifuges are very effective for high temperature and high pressure work. A horizontally oriented decanter centrifuges 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.

A machine running on a centrifugal force to separate different parts is called a centrifuge. Dehydrator Centrifuge is a common device that is usually found on oil or gas drilling sites.

Dewatering machine Centrifuge for oil and gas drilling machine, basically used to dilute the underground liquid and liquid. The main task of the settling centrifuge is to rotate the drilling fluid, thereby destroying the concentration of these fluids. The overall job function of anything is very complicated.

Centrifugal force is the body in the high-speed rotation by the power. They are commonly used to separate components of different densities, such as water and solids. Decanter centrifuge is a special type of centrifuge that separates

solid components from liquids such as drilling waste.

It plays an important role in waste water treatment, chemical industry and food processing. The performance of the settling centrifuge depends on several different factors.
Most of the drilling and handling equipment handling components of the mixture. It is necessary to separate them separately for further processing.

Three types of decanter centrifuges are used in the industry: horizontal, vertical and conveyor. It is basically a high-speed rotating bowl that separates the solid from the liquid matrix. In the case of a drilling industry, inputs are drilling waste.

Centrifuges are easy to install and require less maintenance. Even if skilled operators need to operate them, decanter centrifuges help save a lot of money and improve the overall efficiency of the industry.

Centrifuge provides more flexibility and better feedback mechanisms. This allows the operator to allow the machine to work under different settings to separate the different components.

Decanter Centrifuges of Related Common Challenges

Decanter Centrifuges

Decanter Centrifuges are used in separating suspension of solids phase with particle ≥2μm in diameter for drilling mud and fluids handling.

All machineries will have its own set of requirements to give its user the desired performance and durability and off course the much desired economy. After all “Return on investment” is the mantra that investors care to heed about.

When it comes to solid control equipments, this is no exception. A few careful measures go a long way to ensure that the operators will find the equipment reciprocating their care for them.
The first and foremost one in this aspect is the preventive maintenance of the equipment. The decanter centrifuge as such is low maintenance equipment and has a high capacity of handling the drilling waste treatment , but that should not mean for the operators to simply overlook the state of operation of the equipment.

A very common mistake committed by the operators is the continuous use of equipment without giving it rest and inspection for any wear. The moment any component is spotted showing any signs of wear, operators should consider fixing it, without just pushing it for further use, however small. As it goes with machinery, that all components work in sync, so even a worn out rubber could cause the breakdown of entire equipment. So watch out for any kind of wear or damage.

Another challenge faced by drilling industry in context of economic configuration decanter centrifugeis the lack of trained personnel or operators. With evolving technologies, decanter centrifuges have been made much more automated and need little operational attention. However, to maneuver the equipment to achieve the desired output, need of staffing appropriate personnel is of paramount importance. With ever stringent health and safety regulations, rig operators struggle with their staffing needs.

The high turnover further adds to the problem. Finding the qualified and experienced operators and investing time in resources in training them to bring the up to speed is a very big challenge for project managers.

What are the Principles of Decanter Centrifuge of Kosun

Decanter Centrifuge

Decanter centrifuge separates the solid material mixed with some liquids that contaminates the water and converts the mud into sludge. It is an important component utilized in petrochemical, food processing and oil industries. These industries will not be able to function in the absence of Centrifuge. The centrifugal force is created by the decanter centrifuge and creates the centrifugal force by rotation.

Operational & Functional Principles of decanter centrifuge:
• The principle of decanter centrifuge is based on the theory of gravitational separation. A component with high density settles at the bottom and the component with lesser density suspends upwards.

The decanter centrifuges increases the rate at which the component settles increases due to the use of continuous rotation. This force is from 1000 to 4000 times than the normal gravitational force. This method of separation gives fast results.
Example: When a glass is filled with mud and water, after few minutes the mud will settle at the base of the glass due to its weight. Since the mud is settled at the base become solid, the water comes upward that creates a separation between the mud and water mixture.

This method of separation by rotation can be compared to that of rides of amusement parks. In the same way the decanter centrifuges basically a bowl tube rotates at a very high speed. The bowl tube has an internal conveyor that moves at different velocity but in the same direction.

The decanter centrifuge is ideal equipment for treating waste water. There are various industries where these types of machines are vital.

The 2-phase separation method is used for Waste water treatment, sludge de-watering, and also food processing.

The 3-phase separation process separates two liquids like water and oil, which have different densities and cannot be mixed together, are separated. This 3-phase separation produces edible oil, bio-diesel and oil sludge.
