METHOD OF PRODUCTION OF SINGLET OXYGEN AND A DEVICE FOR ITS REALIZATION Russian patent published in 2004 - IPC

FIELD: laser technology; production of chemical lasers.

SUBSTANCE: the invention is dealt with laser technology, mainly with production of the chemical lasers and may be used in production of the technological oxygen-iodine lasers (OIL). The method of production of the singlet oxygen provides for feeding of alkaline solution of hydrogen dioxide and chlorine gas into the chemical reactor, withdrawal from the reactor of the formed there singlet oxygen and a waste liquid, sustain the liquid in the tank at atmospheric pressure and refrigeration to an operation temperature by injection in it of a liquid low-temperature cooling agent. The low-temperature cooling agent during injection is subjected to dispersion and fed uniformly along the cross section of the liquid in n the lower part of the tank. At that the waste liquid is uniformly distributed on the surfaces of the injector, the cooled liquid is degassed before feeding in the reactor, and the foam generated during injection is destroyed. The device for production of the singlet oxygen includes a chemical reactor, a source of chlorine, a source of a liquid low temperature cooling agent, a tank with an alkaline solution of hydrogen dioxide with placed in it an injector of a liquid low temperature cooling agent, devices of the waste liquid discharge and withdrawal of a gasified low temperature cooling agent. The device has a cylindrical cavity with located there a unit of dispersion of the liquid low temperature cooling agent made in the form of a porous insert in the injector mounted at the outlet of the low temperature cooling agent feeding device with a capability to change the depth of its immersion in the liquid, and a unit of a uniform distribution of the waste liquid placed with a capability of rotation at the outlet of the device of the liquid introduction in the tank and above the injector, and also a unit of degasification of the liquid connected to the reactor and made in the form of a ring-type over-flow channel formed by a cylindrical wall of the tank and by a coaxial with it a cylindrical cavity, and a unit of a foam breakdown mounted above the surface of the liquid in the tank with a capability of its movement in a vertical direction. At that the cooling agent introduction device is placed along the axis of the tank coaxially to the device of the waste liquid introduction. Technical result is the increase reliability and decreased cost of the cooling agent.

EFFECT: the invention allows to increase reliability of the device and to decrease costs of the cooling agent.
