Cyclone Separator By: Waqas Ahmed B.Sc. Mechanical Engg 25 Feb 2014

Definition   Cyclones are mostly used for removing industrials dust from air or process gases. They are the principal type of gassolid separator Most common form of particulate removal gas is spun rapidly – heavier particulate matter to collect on outside of separator by centrifugal force, where it is collected and removed.

Principles of Operation     As with centrifugation, the driving force behind cyclone separation is centrifugal force and the difference in specific gravity between the particle and the carrier gas. In a Cyclone, the air or vapor containing particulate material is forced into along the tangential axis. A helical flow pattern is set up within the chamber. The centrifugal force causes the particles to migrate to the outside of the chamber. Here they fall down to the bottom of the cyclone by gravity. The air moves up the center of the cyclone and reaches the top.

Types

Vertical Cyclone Separator   Vertical cyclone separators are used to remove 99% of free liquids and solids 5 microns and larger. These separators are particularly effective for the removal of solids, such as iron sulphides. The high efficiency of these separators is due to the unique design which enables the separator to be approximately 1/3 the diameter of a conventional separator.

Single-cyclone separators    They create a dual vortex to separate course from fine dust. The main vortex spirals downward and carries most of the coarser dust particles. The inner vortex created near the bottom of the cyclone, spirals upward and carries finer dust particles.

Multi Cyclone separator     It consist of a number of smalldiameter cyclones, operating in parallel and having a common gas inlet and outlet, as shown in the figure. Multi-clones operate on the same principle as cyclones--creating a main downward vortex and an ascending inner vortex. Multi clones are more efficient than single cyclones because they are longer and smaller in diameter. The longer length provides longer residence time while the smaller diameter creates greater centrifugal force. These two factors result in better separation of dust particulates.

Design Procedure  The design parameters for the cyclone separator are as follows: – – – – – – – Length of cylinder L1 = 2D2 Length of cone L2 = 2D2 • Diameter of exit De = 0.5D2 • Height of entrance H = 0.5D2 • Width of entrance B = 0.25D2 • Diameter of dust exit Dd = 0.25D2 • Length of exit duct L3 = 0.125D2 SORUCE: Crawford 1976
