Patent ID: 7799198

Claim:
A chlorine dioxide solution generator comprising: (a) a chlorine dioxide gas source; (b) an absorption loop for effecting the dissolution of chlorine dioxide into a liquid stream, said absorption loop fluidly connected to said chlorine dioxide gas source; and (c) a gas transfer assembly interposed between said chlorine dioxide gas source and said absorption loop, said gas transfer assembly comprising: (1) a gas transfer pump having at least one inlet port for receiving a chlorine dioxide gas stream from said chlorine dioxide gas source and at least one outlet port for discharging a pressurized chlorine dioxide gas stream; and (2) an exhaust manifold assembly extending from said at least one gas transfer pump outlet port, said exhaust manifold assembly comprising at least one manifold conduit defining an interior volume for directing said pressurized chlorine dioxide gas stream from said at least one gas transfer pump outlet port to said absorption loop, wherein said at least one manifold conduit interior volume is sufficiently large to inhibit chlorine dioxide decomposition in said pressurized chlorine dioxide gas stream by inducing a pressurized chlorine dioxide gas stream temperature within said at least one manifold conduit of less than about 163° F. (73° C.), wherein said gas transfer pump has first and second inlet ports for receiving first and second chlorine dioxide gas streams from said chlorine dioxide gas source, wherein said gas transfer pump has first and second outlet ports for discharging first and second pressurized chlorine dioxide gas streams, and wherein said exhaust manifold assembly comprises first and second manifold conduits defining an aggregate manifold conduit interior volume for directing said first and second pressurized chlorine dioxide gas streams, respectively, from said gas transfer pump to said absorption loop, wherein said aggregate manifold conduit interior volume is sufficiently large to inhibit chlorine dioxide decomposition in said first and second pressurized chlorine dioxide gas streams.
