Abstract

A reaction vessel for entraining ozone gas in an aqueous ozone solution for an industrial cleaning system is described. The reaction vessel includes a conical-shaped surface having two or more edges. The conical-shaped surface defines a generally hollow interior, and the two or more edges are in contact with the generally hollow interior. An inlet port is in fluidic communication with a supply of an aqueous ozone solution to supply the aqueous ozone solution to the conical-shaped surface. Nozzles are in fluidic communication with a supply of water, and the nozzles direct the water under pressure at the conical-shaped surface, and the water mixes with the aqueous ozone solution from the inlet port. An outlet is in fluidic communication with the industrial cleaning system. The reaction vessel may receive the aqueous ozone solution from an injector. The reaction vessel reduces the bubbles of ozone gas in the aqueous ozone solution and entrains the bubbles of ozone gas in the aqueous ozone solution to increase the oxidation reduction potential of the aqueous ozone solution.
