Catching fine-dispersed particles in rectangular separator depending on different process parameters

Abstract

We have considered the pressing issue of increasing the efficiency of catching fine solid particles from process gas flows in industrial enterprises. A developed rectangular separator allows collecting fine-dispersed particles of 1–10 μm in diameter from gas flows. It was found that the efficiency of the separator is not less than 99% at the gas flow rate of more than 10 m/s at particle density of 1000 kg/m3. We have investigated the effect of the gas flow velocity and the fine particle size on the collection efficiency and pressure drop in the device. Using the separator as a second cleaning stage, placed in series with the coarse cleaning apparatus, can prevent re-entrainment of valuable material into the atmosphere.
