FIELD: production of primary krypton-xenon concentrate.
SUBSTANCE: the invention presents a device for production of primary krypton-xenon concentrate and is dealt with the air-separating installations by a method of low-temperature rectification. The device contains: a krypton column; a capacitor of the krypton column; an evaporator- dresser; pipelines with the fixture; an evaporator-capacitor with natural circulation and a separator of vapor; a pressure pipeline and a pipe with a loose drainage of a circulating bottom liquid from a vapor divider into the lower manifold of the vapor-generating pipes of the evaporator-capacitor. The krypton column, the capacitor of the krypton column, the evaporator-capacitor, the pressure pipeline and the evaporator-separator are linked by the pipelines with the fixture. At that the capacitor of the krypton column is linked to the evaporator-capacitor through a regulating valve of the bottom liquid. The evaporator-capacitor also contains the adiabatic section located in an elevating branch between a heat exchange surface and a the vapor separator, and the vapor separator has a connecting pipe for withdrawal of the circulating bottom liquid and is supplied with a screen with holes, that is located below the connecting pipe for withdrawal of the circulating bottom liquid. At that the upper butt of the adiabatic section terminates in the vapor divider under the screen with holes, and the regulating valve of the bottom liquid is adjusted to control the level of the bottom liquid in the pipe with the loose drainage. The invention allows to increase contents of krypton and xenon in the primary krypton-xenon concentrate, to increase its pressure, to increase reliability of the device and to reduce losses of krypton and xenon.
EFFECT: invention allows to increase contents of krypton and xenon in the primary krypton-xenon concentrate.
