Understand cyclone design

Abstract

Cyclones are widely used for the separation and recovery of industrial dusts from air or process gases. Cyclones are the principal type of gas-solids separator using centrifugal force. They are simple to construct, of low cost, and are made from a wide range of materials with an ability to operate at high temperatures and pressure. Cyclones are suitable for separating particles where agglomeration occurs. Pollution and emission regulations have compelled designers to study the efficiency of cyclones. Cyclones offer the least expensive means of dust collection. They give low efficiency for collection of particles smaller than 5 [mu]m. A high efficiency of 98% can be achieved on dusts with particle sizes of 0.1 to 0.2 [mu]m that are highly flocculated. The paper discusses the design procedure and operating parameters.
