Abstract
The main aim of this investigation was an experimental analysis of the air cleaning efficiency in a mock-up next-generation air cleaning device – one-level 8-channel industrial cyclone-separator with quarter-rings – while changing parameters of the inner structure and the assessment of the effects of dispersion of particulate matter. Therefore, the research was carried out in two stages: the first stage covered the analysis of the efficiency of the multi-channel cyclone with particulate matter of <20 and <50 μm. During the second stage, a cascade impactor was used to measure the particle collection efficiency in the multi-channel cyclone by fractions: PM1, PM2.5 and PM10. Results of the tests with using the cascade impactor were compared to show changes in the PM composition before and after the multi-channel cyclone-separator. According to the obtained experimental data, the one-level 8-channel cyclone-separator collects 70 to 80 % of PM up to 10 μm in size, 45 to 60 % of PM up to 2.5 μm in size and 21 to 25 % of PM up to 1 μm in size.
