Ozone-based odor control system for controlling hydrogen sulfide and other foul odors

An ozone-based system for reducing odiferous gasses emitted from an odor source, said odor source comprising a containment vessel containing liquid and gasses wherein the level of said liquid changes over time, and said containment vessel includes a vent, said system comprising:

• an ozone generator operably coupled to a control system and configured to controllably produce ozone,
• a reaction chamber coupled to the vent, said reaction chamber comprising
• an outlet through which exhaust gasses flow, said flow being induced by changing liquid level in the containment vessel,
• at least one sensor at the outlet,
• an inlet through which gasses emitted from the vent of the odor source are received,
• an injector through which ozone from the ozone generator is injected at the inlet of the reaction chamber,
• a conduit fluidly and coupling the injector to the ozone generator;
• and
• a flow path from the inlet to the outlet, said flow path defining a pathway for flow of gasses from the inlet to the outlet, said flow path being devoid of any fan, and devoid of any blower, and devoid of any pump for propelling exhaust gasses;
• and
• said at least one sensor at the outlet of the reaction chamber being a sensor configured to sense a parameter from the group consisting of flow direction, flow rate, and odiferous gas concentration, and said at least one sensor being operably coupled to the control system, and
• said control system controlling the production of ozone by the ozone generator based upon the sensed parameter, and
• a conduit fluidly coupling the ozone generator to the injector at the inlet of the reaction chamber, a controllable sparging valve communicatively coupled to and controlled by the control system and fluidly coupled to the conduit between the ozone generator and the injector at the inlet of the reaction chamber, a sparging tube extending from the sparging valve into the liquid in the containment vessel, the sparging valve being operable in ozonation and sparging modes, the control system causing the sparging valve to switch between ozonation and sparging modes, and in sparging mode the system not supplying ozone to the injector, and in sparging mode the system supplying a gas containing oxygen through the sparging tube into the liquid in the containment vessel, and in ozonation mode producing ozone using the ozone generator and supplying the produced ozone to the injector.

• said control system controlling the production of ozone by the ozone generator based upon the sensed parameter, and
• a blower outside of the flow path, said blower having a blower inlet and a blower outlet, said blower drawing ambient air in through the blower inlet and propelling the ambient air from the blower outlet into the flow path towards the gas outlet to produce an ambient air flow, said exhaust gasses from the reaction chamber not contacting the blower;
• and
• induced draft piping extending from the outlet of the blower into the flow path, said induced draft piping having a piping outlet directed towards the gas outlet of the reaction chamber, said induced draft piping supplying a flow of ambient air from the blower into the flow path towards the gas outlet of the reaction chamber, said flow of ambient air creating a pressure differential in the flow path that facilitates flow through the flow path from the gas inlet to the gas outlet of the reaction chamber.
