THE GAS-LIQUID REACTOR (VARIANTS)

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to the implementation of the chemical processes flowing in the gas-liquid medium, in particular to the construction of the gas-liquid reactor with ascendant unit-directional motion of the phases and can be applied to namely the industrial manufacturing of carbamid; the gas-liquid reactor contains the vertical housing with the reagents induct and reaction products educt junction pipes; at the bottom part of the housing there is a mixer including a coaxial tube and a cyclone chamber having a tangential induct junction pipe connected to a first reagent induct junction pipe and an axial educt junction pipe located sidewise the reactor floor; the coaxial tube is inserted into the cylindrical housing of the cyclone chamber; the upper end of the coaxial tube is connected to the second reagent induct junction pipe; the axial educt junction pipe of the mixer is furnished with the diffuser, the lower part of the reactor contains the shield located closely to the reactor floor opposite the educt junction pipe of the mixer; in the second variant the mixer includes at least two connected in series coaxial cyclone chambers having the tangential educt junction pipes connected to the reagents induct junction pipes and axial educt junction pipes located sidewise the reactor floor. ^ EFFECT: increase of the dispersion intensification of the interacting phases and evenness of the reagents allocation in the produced two-phases flow; the additional effect associated with the availability of the shield lies in the prevention of the reactor material tear and wear. ^ 10 cl, 3 dwg
