Product Description

 

How to separater waste oil from oilly sludge

 

(LWS520 Waste Oil Centrifuge)

 

The LWS horizontal screw centrifuge is a new type of Three-phase horizontal screw centrifuge mainly suitable for three phase separation (oil- water- solid ) of separation plant . It is mainly used in waste motor oil separation; oil sludge treatment, crude oil separation, 
 

 

Current status

 

Currently, there are various types of waste oils, including used motor oil, hydraulic oil, cooking oil, industrial lubricants. Improper disposal or release of waste oils contaminate water bodies, soil, and adversely affect ecosystems. Moreover, waste oils pose health risks to both humans and wildlife. Decanter centrifuges provide a solution for reusing waste oils. This technology enables the separation of oil-water mixtures by utilizing centrifugal force. Decanter centrifuges can effectively separate oil from water and solid impurities. the recovered oil can be further processed and reused. This not only helps in reducing pollution and conserving resources but also provides economic benefits by reducing the need for new oil production.

What is a Decanter Centrifuge

The horizontal spiral centrifuge, also known as a horizontal screw centrifuge, is a type of centrifuge that utilizes a rotating screw conveyor mechanism to separate solid particles or liquid-liquid mixtures based on their density. The centrifuge operates by subjecting the mixture to high centrifugal force, causing the denser components to move towards the outer edge of centrifuge while the lighter components stay towards the center. 

 

It consists of a column cone, spiral discharge device, differential system, bearing seat, base, cover, main and auxiliary motors,and electrical system. It is capable of separating materials ranging from 0.002 to 5um. This tricanter centrifuge is commonly used in various industries such as chemical, pharmaceutical, food processing, and wastewater treatment.  

 

It offers advantages such as 24 hours continuous operation, high separation efficiency, and the ability to handle large volumes of feed material. Horizontal spiral centrifuges are particularly effective separating fine particles or emulsions with a narrow density difference. 

 

The LWS520 centrifuge allows for adjustable parameters to optimize the separation process. Parameters such as rotation speed, differential speed, and liquid level can be adjusted to suit the specific characteristics of the oil being processed. Fine-tuning these parameters improves the separation efficiency and product quality.

 

How Does Decanter Centrifuge Works

2 phase Centrifuge working principle: 

After entering into the high-speed turning drum, the solid-phase particles in the mixed liquid run and settle on the drum wallunder the action of greatest centrifugal force; the light liquid settles at the innermost place of the drum under minimum centrifugal force; same as the drum's turning direction, a screw feeder also turns at a high speed, and a constant speed difference is generated by the differential mechanism, then the liquid will be discharged by the liquid outlet.(solid-liquid separation)

 

3 phase Centrifuge working principle

 

Three-phase centrifuge is that two liquid phases and one solid phase enter the centrifuge and expand it thousands of times by relying on the centrifugal force field. The solid phase is settled under the action of centrifugal force, and the two liquid phases are also stratified, so as to realize Solid-liquid-liquid 3-phase separation and discharge them from the body under the action of special mechanism. The whole feeding and separation process is continuous, closed and automatic. (solid-liqui-liquid separation)

Shenzhou LWS 520 Centrifuge for Drilling Waste Management: The drilling fluids recovered by the drilling cuttings dryer should go through the GNLW363 decanter centrifuge to reduce the solids content before returning to the active mud system.  

The LWS three phase decanter centrifuge can be used in WBM, SBM or OBM. LWS 520 Dewatering Centrifuge for water based drilling waste: The result is a polymer enhanced flocculation of colloidal and ultra-fine drilled solids that can be efficiently removed with LWS decanter dewatering centrifuge. Without such a system, operators, would be left with the accumulation of colloidal and ultrafine drilled solids in the mud system. Ultimately leading to excessive mud densities, pipe torque/drag, mud loss, disposal fees, and overall well cost. Shenzhou LWS 520 Centrifuge for Oil Sludge Treatment: The design of the centrifuge on the telescopic skid is popular for oil sludge separation, and waste management rental business. The telescopic skid height is adjustable, It allows the liquid discharged from the centrifuge goes to storage tank by gravity without a transfer pump.
