SINGLET OXYGEN GENERATOR Russian patent published in 2002 - IPC

FIELD: gas generators of oxygen, particularly, generators of singlet oxygen ensuring sufficient productivity for creation of powerful lasers. SUBSTANCE: generator of singlet oxygen has reaction chamber from transparent material having outlet in lower part for spent solution, system of dosed supply of chlorine made in form of two perforated tubes mounted in walls of reaction chamber with outlet from outside and possibility of chlorine supply simultaneously from two sides, jet injector of alkali solution of hydrogen peroxide made in form of plate with calibrated holes, control and measuring system, and slotted cock at outlet of singlet oxygen. Reaction chamber has two reaction zones provided with similar systems of chlorine supply. Reaction zones are interconnected in upper part with outlet cavity serving s outlet of singlet oxygen. Upper part of central wall of reaction chamber has mounted perforated tubes ensuring supply of buffer gas to outlet cavity simultaneously from two sides. Generator has mixing chamber made of monolithic transparent material in which two chambers are formed for supply of alkali solution of hydrogen peroxide to reaction zones through jet injectors installed at outlet of supply chamber. Mounted into each supply chamber are pipe unions ensuring supply of solution from two sides. Formed in center of monolith is mixing chamber in form of widening channel. Mixing chamber has slotted cock in form of cylinder with through recess. Cylinder is kinematically connected with air drive. Generator control and measuring system has two pressure pickups located in pipe unions of channels made in central part of front walls of reaction chamber and four photodetectors for determination of concentration of singlet oxygen and water. Photodetectors are located in blind holes of mixing chamber monolith. EFFECT: increased productivity of generator due to increased yield of singlet oxygen. 5 dwg
