FIELD: gas industry.
SUBSTANCE: invention relates to a nozzle for distribution of a mixture of gas-liquid fluids in a reactor with supply from top to bottom. Technical result is achieved by nozzle, which contains nozzle housing, having wall having inner and outer surfaces. At that, the nozzle housing contains part of the housing for the gas inlet zone, part of the housing for the liquid inlet zone and part of the housing for the outlet zone. Part of the housing for the gas inlet zone forms the space of the gas inlet zone and comprises displaced inlet holes for gas to pass through them into the space of the gas inlet zone. Part of the housing for the liquid inlet zone forms the space of the liquid inlet zone and contains a liquid inlet hole for liquid passing through it into the liquid inlet zone space. Spaces of gas and liquid inlet zones are hydraulically connected. Nozzle cover is located in the upper part of the nozzle body and closes the upper part of the body part for the gas inlet zone. Convergent-divergent nozzle limiter is located in the outlet zone in the lower part of the nozzle body. At that, the nozzle limiter comprises a narrowing zone in the form of a truncated cone and an expansion zone in the form of a truncated cone and is hydraulically connected to the liquid inlet zone. Gas inlets are located at different distances from the upper part of the nozzle body along the length of the nozzle body. Gas inlet part of the housing comprises two gas inlets spaced about 180 degrees from each other, or three gas inlets spaced about 120 degrees from each other, or four gas inlets spaced about 90 degrees from each other.
EFFECT: effective mixing and distribution of liquid and gaseous phases in the reactor with simultaneous reduction of pressure drop through the nozzle.
