Abstract
Pollutant molecules and/or particles are removed from a stream of polluted gas utilizing moisture-containing sonic or supersonic shock waves passing through the stream of polluted gas stream to alter, change, modify, grow or otherwise change the molecules and/or particles to render then removable or separable from the gas stream.
Claims28
In a process for removing small sized pollutants from a polluted gas stream containing the pollutants, the improvement comprising:
- passing moisture-containing sonic or supersonic shock waves through a subsonic flow of the polluted gas stream as the polluted gas steam exits a subsonic free jet nozzle and enters into a contiguous chamber having an area of pressure of <14.7 psia adjacent the region of the free jet nozzle exit, whereby the pollutants are modified or grown as they pass through the shock waves and thereby become removable or separable from the polluted gas stream.
A process for removal of pollutants from a polluted gas stream containing said pollutants, the process comprising:
- (a) providing a subsonic flow of the polluted gas stream through a subsonic free jet nozzle into a chamber having an area of pressure of <14.7 psia;
- (b) introducing into the chamber, in the area of pressure of <14.7 psia and at one or more points adjacent entry of the polluted gas stream from the free jet nozzle into the chamber, moisture-containing sonic or supersonic shock waves which pass through the polluted gas stream in the chamber causing the pollutants to be modified or grown in size;
- and
- (c) removing the modified or grown pollutants from the stream of polluted gas.
Apparatus for removing pollutants from a polluted gas stream containing said pollutants, the apparatus comprising:
- (a) a subsonic free jet nozzle with an exit for providing a flow of said polluted gas stream;
- (b) a chamber having an entry end and exit end, the entry end being connected to the subsonic free jet nozzle and surrounding the exit of the subsonic free jet nozzle for receiving the flow of the polluted gas stream in an area of the chamber having a pressure of <14.7 psia as the stream of polluted gas exits the subsonic free jet nozzle;
- (c) one or more sonic or supersonic nozzles surrounding the exit of the subsonic free jet nozzle for providing moisture-containing sonic or supersonic shock waves for moving through the flow of polluted gas in the chamber and modifying or growing in size the pollutants in the polluted gas stream for removal of the pollutants from the polluted gas stream;
- and
- (d) one or more separators connected to the chamber for separating the modified or grown pollutants from the polluted gas stream.
