ABSTRACT:
A chamber has a drive shaft rotatably mounted therein and extending along substantially the entire longitudinal extent of the chamber. This drive shaft is rotatably driven by a motor at a speed of 1,200-10,000 rpm. A plurality of screens having a mesh of 6-10 mesh are spaced from each other along the longitudinal extent of the chamber in opposing relationship and attached to the drive shaft for rotation therewith. Above the screens are a pair of discs which are attached to the shaft for rotation therewith and longitudinally spaced from each other. First and second similar plates having circular apertures formed therein are fixedly attached to the chamber in longitudinally spaced relationship, the first and second discs being positioned in the apertures of said first and second plates respectively. Gas to be purified is fed into the bottom of the chamber and driven upwardly by a compressor fan attached to the drive shaft. The gas first passes through the rotating screens which comminute and modify the surface characteristics of the microparticulates in the gas and then through circular vortex zones formed between the spinning discs and their opposing plates where the particles are sheared and separated from the gas by centrifugal expelling fans attached to the shaft. Purified gas is fed out from the top of the chamber for utilization in driving a gas turbine or other purpose.
