Titanium Oil Extraction Decanter 3 Phase Centrifuge

Product Description

3-PHASE SEPARATING DECANTER FOR INDUSTRIAL FLUIDS 3-Phase separating decanters for industrial fluids from SHENZHOU is a continuously operating centrifuges with a horizontal solid-wall bowl developed specifically for the treatment of waste oil, MARPOL liquids, waste emulsions and oily waste water. The frame is of open design with gravity or under pressure discharge of the clarified liquid phase.
The feedstock enters the decanter through feed tube and flows into the centrifugation space through the distributor. The conveyor screw transports the solids to the solids discharge. The level of the liquid can be adjusted by fitting regulating rings or disks of the required inner diameter. Separation of the two liquid phases takes place in the separation zone, whereby the light phase flows towards the bowl axis, and the heavy phase towards the bowl wall.
Regarding the discharge of the liquid phases 3-Phase Separating Decanters are available in numerous designs. Liquid phases can be discharged by gravity or under pressure by centripetal pump. In the case of a 3-Phase Separating Decanter with centripetal pump for the light phase and gravity discharge of the heavy phase, the light liquid phase leaves the centrifugation space over an exchangeable regulating ring and is discharged under pressure by the centripetal pump. At the same time, the heavy liquid phase is discharged under gravity through exchangeable regulating tubes.
Another technical variant is the case of a 3-Phase Separating Decanter with centripetal pump for the heavy phase and gravity discharge of the light phase. The choice of the appropriate design depends on the product to be separated and the lay-out of the customer installation. Features & Benefits All product-contacting parts are made of stainless steel Shallow pond design Minimal power consumption Highest g-force for maximum efficiency Innovative adjustable scroll drive with the following features:
- drive with intelligent kinematics for high differential speeds and torques

- Automatic adjustment of the differential speed due to the frequency controlled variable speed motor The scroll can be operated also with stationary bowl Gentle feed geometry for optimum flocculation and low wear Low space requirement Good accessibility to all components Easy to operate and maintain Explosion-proof design available High torque gearbox Liquid discharge: free gravity discharge or under pressure Decanter Feed Pipe Inlet The product is fed into the decanter scroll's inlet chamber through a centrally located feed pipe. It then travels through the distributor apertures into the decanter bowl after modest pre-acceleration.
Decanter Bowl The cylindrical/conical decanter bowl rotates at a pre-set speed that is perfectly calibrated for the purpose. The slurry rotates at the working speed within the bowl, forming a cylindrical layer on the bowl wall. Under the influence of centrifugal force, the solids in the product settle on the inner wall of the bowl due to their higher density. The length of the cylindrical bowl section and the cone angle are chosen to fit the application's specific needs.
Decanter Scroll The separated solids are conveyed toward the conical end of the bowl by the decanter scroll, which rotates at a slightly different speed than the bowl. The solids' residence period in the decanter bowl is determined by this differential speed. Cake dryness is influenced by the amount of time it spends in the oven. It may be modified by adjusting the scroll's differential speed, resulting in appropriate separation. Scrolls are constructed differently depending on the application and activity.
Solids Discharge Settled solids are ejected into the solids housing through ports at the conical end of the bowl and fall through the discharge chute.
Overflow The cleared liquids (fluid phase) flow to the bowl's cylindrical end and exit through weir plates. The pond depth (liquid layer) in the bowl is regulated by extremely precisely adjustable weir plates (overflow weirs) in these apertures. The liquid is gathered in the drain housing and expelled via gravity.
Impeller The clarified liquid can alternatively be expelled via an impeller and discharged from the bowl under pressure in a closed system as an alternative to the overflow weir. A separate chamber pump is no longer required. The adjustable impeller, a more advanced type, allows for infinitely changeable pond depth control during the run. This allows for quick and delicate adjustments to changing conditions without shutting down the decanter centrifuge.

Types Of Decanters There are several types of decanter centrifuges currently utilized in the industry, the most widely recognized are vertical, horizontal and conveyor centrifuges. The principle behind a decanter centrifuge is based on the theory of gravitational separation. For example, if you fill a vessel with a mixture of mud and water, over time the weight of the mud will cause it to settle down at the base of the vessel. With the mud congealed at the bottom, the water will be forced upwards, creating a clear separation between the two.
Decanter Principles A decanter centrifuge employs the same principles of gravitational force. However, unlike the glass mixture, the process is expedited through the use of continuous rotation. In fact, rotation provides anywhere from 1000 to 4000 times the normal gravitational force, reducing the time required for separation from hours to seconds.
Rotational Separation The concept of rotational separation is similar to rides found at amusement parks and county fairgrounds. In these rides, placing yourself at an angle allows you to overcome the gravitational forces induced by rotation. Similarly, a decanter centrifuge is essentially a bowl tube that rotates at an extremely high speed. The bowl tube is equipped with an internal conveyor which moves in the same direction but at a different velocity.
How the Decanter Process Works: 1: The slurry is brought into the centrifuge through an intake pipe and onto a conveyor. 2: Utilizing an internal feed compartment, the conveyor moves the slurry through a nozzle into the bowl. 3: The bowl rotates at high speeds to induce centrifugal forces. 4: High speed rotation separates the solid material from the liquid in a matter of seconds. 5: The conveyor delivers the solid material upwards where it is discharged through a nozzle. 6: The solid material removed, the purified liquid is released from a separate output. The ability to purify a liquid makes decanter centrifuges ideal for waste water treatment facilities. However, there are variety of industries for which such centrifuges play an important role. Similar to other decanter equipment, centrifuges are simple to install and do not require a foundation to build upon. Their efficiency saves time and materials and is an essential component for many blue collar industries What is a Decanter Centrifuge? Horizontal Bowl centrifuges are also known as decanter centrifuges, centrifugal decanters or simply decanter machines and are primarily used for separation of liquids from appreciable amounts of solids. Decanters can separate over 50% (v/v) solids from liquids on a continuous basis. Typical industrial decanter applications include Crude Oil Tank Bottoms; Waste Oil; Industrial Wastewater; Sludge Dewatering; Fish Meal; WVO/UVO De-Sludging; Paint Sludge; Rendering etc. etc. For More Information on Decanter Centrifuge Repair Call Centrifuge World.
How does it work? A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer. Different dam plates are used to vary the depth of the liquid - the so-called pond - as required.
The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually "ploughed" out of the pond and up the conical "beach". The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl.
Horizontal Decanter Centrifuges Centrifuge World offers a wide variety of horizontal continuous cleaning decanter centrifuges which provide effective, low-maintenance solutions to continuous liquid clarifying and / or solids dewatering with advanced process and mechanical performance features.
