METHOD AND DEVICE FOR PRODUCING IODINE-CONTAINING GAS Russian patent published in 2004 - IPC

FIELD: laser engineering.

SUBSTANCE: proposed method includes placement of crystalline iodine in the form of preformed enclosure on inner surface of sealed chamber, heating of the latter through chamber walls, uniform distribution of carrier gas along enclosure surface, and supply of infrared rays from chamber interior while regulating their intensity according to measured concentration of iodine vapors in gas. Device implementing this method has sealed chamber communicating with carrier gas source. Outer surface of chamber mounts heating source, and crystalline iodine in the form of enclosure is disposed on its inner surface; variable-intensity infrared radiation source, devices for uniform admission of carrier gas along enclosure surface and for outlet of iodine-containing gas are installed in space confined by enclosure. Iodine concentration measuring unit connected to radiation source intensity regulation unit is mounted at device outlet.

EFFECT: enhanced productivity and precision of iodine concentration maintenance in iodine-containing gas; enhanced reliability and reduced maintenance charges.
