Cyclonic scrubbers are generally low-to medium-energy devices, with pressure drops of 4 to 25 cm ( 1.5 to 10 in ) of water.
2.
By introducing the inlet gas tangentially into the spray chamber, the cyclonic scrubber increases gas velocities ( thus, particulate velocities ) to approximately 60 to 180 m / s ( 200 to 600 ft / s ).
