Mass exchanger with discrete feed of gas

FIELD: process engineering. SUBSTANCE: invention relates to nuclear power engineering, particularly, to research and power reactors with liquid-metal lead-bearing heat carrier. Mass exchanger with discrete feed of gas consists of vessel composed by housing 8, bottom 3 and circular cover 9. Said vessel accommodates bottom grate 11 arranged above heat carrier 14, solid-phase oxidiser 13 arranged above bottom grate 11 and gas circuit. Said solid-phase oxidiser comprises gas flow booster 7 and gas feed pipeline 15. One part of said pipeline communicates gas chamber 2 with heat carrier 19 and gas inlet of flow booster 7 while opposite part communicated gas flow booster outlet via circular cover 9 with mass exchanger inside. For pre-oxidation of heat carrier mixing chamber is used composed by housing lower part, bottom and bottom grate. EFFECT: ease of servicing, decreased overall dimensions. 6 cl, 1 dwg, 1 ex
