JYF-W-A/B Type Oil Separator  
Description of this Oil Separator:
No need to dose coagulant, automatic separation, small volume, high efficiency, low investment.

1 Design Principle
●Toroidal swirl principle
The Oil-water mixture flows first into the front-end of the toroidal swirl separator and forms a high-speed swirl. Since the density of the light and heavy components in the mixture is different, under the centrifugal force generated by high speed rotation, the concentrated heavy components flow out from the bottom, while the light components (oil) flow to the selecting center, and are discharged from the overflow outlet to achieve solid-liquid separation and oil-water separation. The basic principle is centrifugal and sedimental effect.

●Coalescence and absorption principle
Coalescence is also called coarse graining. The fine particles in the discontinuous phase of the dispersion are absorbed to the surface of lipophilic material and coalesce into bigger particles, which are separated from the continuous phase under the force of water. The physical process is coalescence. The dispersive oil drops meet the stop flow in the coarse graining bed and are absorbed by the stuffing. Coalescence and floatation happen at the same time. Within a short time, the machine can achieve a high degreasing rate. The degreasing rate is proportional to the size of oil particles in water, and inverse proportional to the size of particles and stuffing.

●Stokes formula and shallow principle
In the oil-water mixture flow path made of multi-layer corrugated board, the way in which the sap flow moves is laminar flow. The floatation terminal velocity of oil droplets in the oil-water mixture abides by Stokes formula. According to Stokes formula, the buoyant velocity of oil droplets in water is proportional to the square on diameter of the oil droplets. The larger diameter, the faster the oil particles float, the easier oil separated. Meanwhile the removal efficiency of oil droplets is also related to the surface load Q / A, but has nothing to do with the height of buoyancy. This is called "shallow pool principle." Therefore, the use of multilayer structure, increase the buoyant area, maintain laminar flow are conducive to oil-water separation.

2 Technical Characteristics

There is no need to dose coagulant during the oil-water separation process. The waste oil separated can be used as commercial crude, recycled or refined, which turns waste into wealth and creates economic benefits. Meanwhile, the oil removal method produces no other sludge, which can save the expense of treating the waste.

Small volume, high efficiency, low investment.

Sealing process, no gas exhausted, no secondary pollution, clean and safe production.

No mechanical moving parts inside the device, no stoppage, low maintenance expense.

Automatic separation, high automation level.

Coalescence materials and corrugated materials installed inside the device are made of stainless steel or FRP (Fiber Reinforced Plastics). High mechanical strength, resistance to high temperature and corrosion, pro-oil properties, large surface area, long life cycle, easy maintenance, using steam or hot water to wash.

Can be used for degreasing, dehydration or solid-liquid separation.

The technical level has reached and surpassed the highest level of the same type equipment both at home and abroad.

3 Sphere of Application
