Effect of External Cyclone Diameter on Performance of a

2019/8/20Therefore, if a two-stage cyclone is designed, to ensure a high total separation efficiency, the external cyclone diameter should be at least four times the internal cyclone diameter. The test points for testing the internal flow field and concentration field of the cyclone are the same, and the arrangement of the measuring points and the test results is shown in Figure Figure2 2 .

Cyclone Separators Selection Guide

2020/8/28Dust conditions at the inlet of the cyclone can include material type, specific gravity, bulk density (lb/ft3), dust load (lb/hr or grains/ft3 air), and particle size distribution. Sizing, densities, and loads are needed to determine the required capacity and design specifications for sufficient capture. Get price

Fundamentals of Cyclone Design and Operation

Any separation at all causes pressure loss and, in general, the greater the separation, the greater the pressure drop needed to effect it. The percentage of dust in suspension which is separated from the gas-dust mixture is commonly called the collection or separation efficiency. Get price

An experimental investigation on gas flow field dynamic

2020/8/1Cyclones serve as gas solid separation devices in a variety of modern industrial applications, as well as in scientific and engineering gas swirling flow analyses. The working principle of a cyclone designed for any such application is centrifugal separation under the condition of a centrifugal force field formed by a highly swirling flow ( Hoffmann and Stein, 2007, Swamee et al., 2010 ).

Powder Recovery Cyclones

Inside the cyclone, vortex separation causes the solid particles to hit the outside wall of the cyclone and fall to the catchpot at the base of the cyclone. This allows 'clean' air to pass downstream (to the dust extraction source) and prevents a build-up of material in the filters, which can be time consuming and expensive to replace. Get price
