The Impact of a Ceramic Wear Liner on the Separation Efficiency of a Particular Cyclone Dust Collector

Cyclone separators are widely used in the gas solid separation processes. Their dimensions and configurations have a great influence on their performance and they have been widely studied in literature. In this research, the impacts of using a ceramic wear liner inside the wall of a special dust collector cyclone, installed in the Golgohar mining and industrial company in Iran, is investigated. In this research some numerical calculations and software analysis, based on the CFD, have been carried out and the results have been compared with the results of the practical tests and recorded data. This comparison shows the conformity of the results of the practical tests and the calculated results. In this research, the flow is a two-phase, gas-solid, type and the collision of the solid materials, which are mainly iron material with 200∼700 micron dimensions, with the cyclone wall will increase the erosion. Therefore, to reduce the erosion a special ceramic wear liner is used as a protective layer for cyclone wall. Adding this protective layer has changed the geometry of the cyclone wall from different aspects; so the impacts of this type of liner on the performance and the separation efficiency of the dust collector cyclone should be investigated. The dilute two phase flow inside a cyclone is simulated using an Euler-Lagrange hybrid method. The gas phase is governed by the Navier-Stokes equations. This investigation can be a starting point for more research that can be result in producing more appropriate and efficient cyclones. For more accuracy, the comparison have been done for different speed of flow and the results show that this liner has a negative impact on the dust separation efficiency in this cyclone.
