Pircon, L J

Apparatus operating at low pressure drop and low initial velocity for removing pollutants down to submicron sizes from gas streams comprising a nozzle means accelerating the gas flow to about four times its entering velocity into a large expansion chamber having an impinger area for removal of pollutants. This is a method of removing pollutants down to sub-micron size at high efficiency by passing the polluted gas through a nozzle having specific geometry into an expansion chamber and impinging the pollutants upon an impinging area and removing them from the system.
