Curved semi-cylinders on the cyclone level were placed in different positions: 50/50 – the flow coming from the
channel is divided in curved semi-cylinders into peripheral (reciprocating) and transit (moving to the next channel)
flows. Peripheral and transit flows make 50 % of the total incoming flow, i.e. flow distribution ratios are equal; in
the case of 75/25 ratio the peripheral flow makes 75 % and the transit flow makes 25 % of the total flow incoming
from the upstream channel; in the case of 25/75 ratio the peripheral flow makes 25 % and the transit flow makes 75
% of the total flow incoming from the upstream channel (Fig. 1).
6-channel and 8-channel three level cyclones were designed for the testing of air cleaning efficiency. Air flow
rates of 17 m/s and 18 m/s were additionally used to determine the optimal cleaning efficiency parameters.
Particulate matter of wood ash with some of the lowest density (below or equal to 1000 kg/m3) and granite
particular matter having the highest density (above 2500 kg/m3) were selected to determine the changes in air
cleaning efficiency when the air flow is polluted with particles of different density.
Research goal: Determine the effect of new generation equipment design solutions, i.e. the number of cyclone
levels and half-cylinders (quarter-cylinders), position, adjustment of half-cylinders and quarter-cylinders, change of
air flow distribution ratios, the average air flow rate in the channel and particular matter of different origin as well as
their dispersion, on the reduction of particle concentration in polluted air flow.
