Product Description

Shenzhou Automatic Disc Stack Separator Centrifuge for Extract Lanolin From Wool Washing Water

Description:

 

Wool Grease is a natural substance excreted from the sebaceous gland attached to the root of each wool fibre in the basal layer of the sheep's skin.
Lanolin separators are used for extracting oil and fat from wool-washing waste water and obtaining relatively pure lanolin and meanwhile reducing the cost of waste water treatment.
Lanolin is the best oil grease deprived from the natural wool,today,the biggest wool producing county is Australia.,Lanolin has big usage in our daily life,such as rust protection agent,cosmetic.first class lubrication media etc,it is the by product of the wool factory,but it is very valuable.Factory hopes to get more and pure Lanolin to get more profit,in the other hand,they have to separate the lanolin to meet the environmental effluent standard.

Working Principle

1. SINGLE-STAGE WOOL GREASE RECOVERY
Scour effluent heated to at least 64°C is fed from above into the centre section of the primary centrifuge as shown in Figure 3. Inside the centrifuge the effluent flows into the stack of cone shaped discs, which rotate at approximately 6000rpm [1-10]. In the disc stack the lighter wool grease flows upwards between the discs towards the centre of the bowl where it is discharged as primary cream. A second emulsion phase flows downwards between the discs due to its higher density, from where it flows up the walls of the outer bowl and is also discharged at the top of the centrifuge. Any dirt and heavy solids in the feed are also carried downwards between the discs but, due to having higher density than the aqueous emulsion phase, do not flow up the walls with the emulsion phase and are continuously discharged through jets in the bottom of the bowl wall. The
primary cream is then fed into a thermal-cracking tank where it is held for in excess of five hours at approximately 90°C. Over this period the cream splits into three distinct phases.
After the solution has been given time to separate, the heavy aqueous phase is drawn off the bottom of the tank to drain, the emulsion phase is recycled to the centrifuge and then the wool grease floating in the top of the tank is drawn off into drums. Due to the rising value of recovered wool grease and mounting restrictions on effluent discharges, single stage wool grease recovery is no longer used in the main stream scouring industry.
2.TWO-STAGE WOOL GREASE RECOVERY
In a two-stage system, primary centrifuges and thermal cracking tanks are again used, but this time the cream and emulsion from the cracking tank is fed to a bank of secondary centrifuges for further purification. In a two- stage system the cream from the primary centrifuges is around 60 - 80% wool wax. The product from the
secondary centrifuges is typically in excess of 99% pure.
3. THREE-STAGE WOOL GREASE RECOVERY
In a three-stage system a greater overall proportion of the wool grease is recovered from the effluent by the primary centrifuges. The resultant primary cream however is typically only 10 - 20% grease. This high volume low strength primary cream is then thermally cracked and passed through the secondary centrifuge at approximately 90°C resulting in a secondary cream containing 70- 80% wool grease. The cream from the secondary centrifuge, still at 90°C, is then passed to a purifying centrifuge where it is mixed with clean hot water (which aids in washing impurities from the grease) and is then separated to produce wool grease with purity in excess of 99%.

Disc centrifuge Details

The disc separator is in vertical structure. The drum is mounted on the upper end of the vertical axis, which is driven by a motor and rotates at a high speed. There is a set of disc - shaped parts that are stacked together in the drum, with a small gap among them. When the suspension (or emulsion), which is pumped into the drum by feeding tube located in the center of the drum, pass through the gap between the discs, solid particles (or droplets) would settle down to form sediment (or liquid layer) on the disc by centrifuge force, and then the sediment slid along the surface of the disc and separated from the disc to accumulate in the largest diameter of the drum. At last, the separated liquid discharged from the outlet. The disc is utilized to shorten the settling distance of solid particles or droplets, enlarge the settlement area of the drum, and improve the production capacity of the separator. The solids accumulated in the drum are removed from the drum by manual after the machine stop, or out of the drum in the case of a dregs machine without stopping.
