Abstract

Held cyclone operation analysis at different flow rates. In the absence of dust deposits on the surface of the device in countercurrent conical cyclone particle concentration distribution in the circumferential direction in the wall region is uneven rope-formed particles to form clots. At low concentrations where clots stably transported stream at any position of the cyclone can be made based on evaluation of the speed distribution of gas and particles in the bunches movement. In work the analysis of work of a cyclone is carried out at various speeds of a stream.

Highlights

Processes of a current of the two-phase environment in the cyclone chamber are difficult and still there is no physically reasonable model of transformation of the disperse environment from an aerosol state in bulk in the receiver
For larger particle concentrations at which the weight of bundles becomes sufficient for the manifestation of the forces of gravity, calculation of flow characteristics are shown in [3]

Summary

Introduction

Processes of a current of the two-phase environment in the cyclone chamber are difficult and still there is no physically reasonable model of transformation of the disperse environment from an aerosol state in bulk in the receiver. At the boundary of the swirling flow near the boundary surface of gas flow tangential speed decreases and becomes zero at the wall of the flow itself. In the absence of dust deposits on the device surface in a conical counter-cyclone in cinders-output hole concentration of particles increases hundreds of times, causing the flow of braking due to the increased value of the shear stress on the wall. For larger particle concentrations at which the weight of bundles becomes sufficient for the manifestation of the forces of gravity, calculation of flow characteristics are shown in [3]. At which the bundles stably transported cyclone flow at any position can be made based on evaluation of the speed distribution of gas and particles in the harness movement
