Patent ID: 7611684

Claim:
An effluent gas scrubber comprising: an inlet port; a scrubbing fluid reservoir; a first chamber in fluid communication with the inlet port via a transition tube having an interior surface; an input configured to deliver a fluid to the interior surface in a manner that coats the interior surface with the fluid; a nozzle in the first chamber, in fluid communication with the scrubbing fluid reservoir and oriented to spray fluid from the scrubbing fluid reservoir into the first chamber; a second chamber in fluid communication with the first chamber; a nozzle in the second chamber, in fluid communication with the scrubbing fluid reservoir and oriented to spray fluid from the scrubbing fluid reservoir into the second chamber; an outlet port in fluid communication with the second chamber; an oxidizer tank; and an oxidation-reduction potential probe that measures the oxidation-reduction potential of fluid in the scrubbing fluid reservoir and responsive to the measured oxidation-reduction potential causes an oxidizer to flow from the oxidizer tank to the scrubbing fluid reservoir.
