Comparison of a Classical Cyclone Separator and Protruding Surface Cyclone Separator using CFD Software

Abstract

Industrial smoke contains various hazardous particles, ash namely to be one of the various substances. The cyclone separator is a specially designed device used to separate the ash particles from the stream of air. The stream of dirt and air mixture flows in two vortexes, the inner vortex and the outer vortex, this device in turns acts as a scrubber and the ash particles get collected down in the ash collector whereas the fresh air stream is released by the device. To increase the efficiency, i.e. to increase the ash collecting capacity of the device, we have tried to compare a classical cyclone separator with the one we created which has protruding surfaces internally and the comparative analysis is done using the CFD software ANSYS R16.0.

“…Selection of gas treatment equipment should consider a number of factors such as physical/ chemical characteristics of polluted gas and characteristics and contents of gaseous pollutants and PM. Complex pollution of dusted gases requires the use of multistage treatment systems, including dry and wet cleaning devices, which increases capital and operating costs [17,18]. Apparatus for complex purification of off gases operates in the regime of developed turbulence and is a promising tool for solving this problem [13,14].…”

“…The reason is a simple structure, low cost and easy operation of these devices. Cyclones are recommended for gas pre-treatment, while the secondary treatment phase usually involves other air treatment devices [15][16][17] collecting particles smaller than 20 μm. Multi-stage air treatment systems, however, are more complex and expensive [18].…”
