Abstract
The present invention is directed to a chlorine dioxide generation apparatus and to a method of generating chlorine dioxide utilizing this apparatus. The novel apparatus comprises a generator having a mix and dwell premix chamber interconnected with a venturi preferably, or to some other source of vacuum, undiluted reactants are permitted to mix and react in the premix chamber, prior to any dilution as by water or other fluid flowing through a venturi eductor to deliver the generated chlorine dioxide to its place of storage or utilization.
Claims9
A process for the preparation of chlorine dioxide which comprises:
- (a) substantially instantaneously reacting compounds, which when reacted together yield chlorine dioxide, in the absence of dilution water, in a reaction zone sized to permit only substantially instantaneous contact of said compounds.
- (b) transferring the generated chlorine dioxide from the reaction zone to another location by immediately educting the chlorine dioxide by suction generated by the movement of a diluting fluid through a venturi, the flow rate of said diluting fluid being correlated to the flow rate of the reacting compounds to avoid any buildup of chlorine dioxide in the reaction zone.
The process of preparing chlorine dioxide which comprises:
- (a) introducing an aqueous alkaline chlorite and gaseous chlorine into opposite ends of a tee shaped reaction chamber in the absence of dilution water;
- (b) reacting said chlorite and chlorine momentarily;
- (c) educting the formed chlorine dioxide from said chamber by moving a diluting fluid through a venturi;
- (d) diluting the concentration of said chlorine dioxide with said fluid.
The process of preparing chlorine dioxide which comprises:
- (a) introducing an alkaline chlorite, an alkaline hypochlorite and a mineral acid into a tee shaped reaction chamber;
- (b) momentarily reacting said chlorite hypochlorite and acid in the absence of diluting water to form chlorine dioxide;
- (c) educting the chlorine dioxide from said chamber by moving a diluting fluid through a venturi;
- (d) diluting the chlorine dioxide concentration with said fluid.
