The investigated next-generation multichannel cyclones are designed installing the tangential air flow inlet by means of aerodynamic characteristics of cyclones with the productivity and the efficiency higher than the conventional cyclone devices. These devices with considerably improved construction over conventional cyclones analogue are used for dry particles separation from the gas-air flow. Designed cyclone the gas cleaning device having a curvilinear channels, which can clean up the contaminated air stream from small-sizes particulate matter (PM), in addition to being easy to install and operate. The aim of the described research – to analyze of the cyclone with curved channels cleaning efficiency dependence on the particle dispersity and their different nature. These studies were tested for particulate eliminating efficiency under dispersity dependence, varying inlet air flow velocity in the cyclone. Investigated 1 µm, 2 µm, 5 µm and 10 µm size glass, technical salt and clay PM, with bulk densities respectively 2500 kg/m3 , 2100 kg/m3 , 1700 kg/m3 . Investigating the efficiency of the change were examined 2 g/m3 and 5 g/m3 contaminants in polluted air flow levels. It was found that the 10 µm size glass PM eliminating efficiency cyclone separator at 5 g/m3 and 20 m/s inlet velocity is 69%.

Keywords: cyclone separator; particulate matter; cleaning efficiency; curved channel.
