The investigation of effects of silica on the environment and prevent of release the silica particles with simulation of gas-solid flow in a gas cyclone

In this paper, in order to reduce the morbidity of released silica particles from the cement factory, a gas cyclone separator is used in track of the gas-solid flow which is released to the environment. The gas-solid flow with turbulence model of RNG k-ε has been simulated and morbidity of released silica particles to the environment has been examined before and after using of the cyclone. The results show about 99% of solid particles with diameters between 5-15μm -causing Shortness of breath and choking- are traped and 80% of solid particles with diameters between 0.5-5μm -causing serious illness such as silicosis and lung cancer- are also trapped
