Difference Between Purifier and Clarifier

What is the Difference Between Purifier and Clarifier? A purifier is a type of centrifugal separator that we can use to separate two liquids with different densities while a clarifier is a type of centrifugal separator that we can use to separate solid impurities from fuel.

How do you change clarifier to purifier?

How do you change purifier to clarifier ?

1. Open up the purifier and set the blind disc at the bottom of the disc stack.
2. The water outlet is blocked by a seal on the gravity disc.
3. Blank off the sealing water inlet line.

What is clarifier in ship?

Centrifugal separators used for the separation of two liquids of different densities (fuel and water) are known as purifiers and those used for separating solid impurities are known as clarifiers. Purifiers will also remove some solids and clarifiers will also remove small quantities of water.

What is the use of purifier in ship?

A high-speed centrifugal purifier is used on a ship to separate unwanted contaminants from lube and fuel oil. On the ship, we use separate marine purifiers for lube and fuel oil.

What is blind disc in purifier?

Blind Disc means the disc is blind. It means there is no holes in the disc. It is used to convert the purifier into clarifier. It is inserted at the bottom of the disk stack, because there are no holes.

Why back pressure is maintained in purifier?

Back Pressure: The back pressure should be adjusted after the purifier is started. The back pressure varies as the temperature, density, viscosity of feed oil inlet varies. The back pressure ensures that the oil paring disc is immersed in the clean oil on the way of pumping to the clean oil tank.

What is the principle of purifier?

An oil purifier uses the same principle for separating dirt or water from oil. Instead of using gravity, it uses centrifugal force. Through a system of gears, a centrifuge bowl is rotated at high speeds. Oil to be purified is allowed to enter the bowl while it is rotating.

What is the purpose of a clarifier?

A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the liquid are called scum.

What is gravity disc in purifier?

>Gravity disc in purifier is the one which controls the output of the quality of the fuel. >Dam ring is responsible for creating the interface between the oil and water. >Back pressure is maintain by gravity disc. Must Read:> Alarms And Shut Downs (Safeties) in Purifier. Purifier Gravity Disc Size Selection.

What is a Marine purifier?

On ships, separate marine purifiers are used for fuel and lube oil. ... It is a purifier that separates two liquid substances based on their difference in density with the use of gravity disc to separate solid and water and sealing water as an operator with two-holed lower discs; one for water and other for oil.

What is Interface purifier?

Ans: The Interface Is The Boundaries Of Layers Between The Separating Liquid And It Is Important To Maintain Inside The Bowl Of The Centrifugal Separator To Attain The Effectiveness Of Purification.

What is purifier overflow?

Purifier overflow reasons:

Excessive sludge deposit inside the bowl. Sealing water low. Excessive back pressure or service tank valve closed. Feed oil temperature high or low. ... Sealing ring leakage(between bowl and hood)

What is the purpose main engine Lo purifier?

Main Engine LO purifier takes suction from main engine LO sump and purifies the oil. Its feed temperature is maintained around 90 degrees Celsius (as maximum density difference is achieved at that temperature) to allow efficient separation.
