GAS-LIQUID REACTOR (VARIANT EMBODIMENTS)

摘要

The invention relates to design of a gas-liquid reactor with a rising unidirectional phase movement and can be used, in particular, for the industrial production of urea. Pipes for introducing reactants into the vertical entrained-flow gas-liquid reactor are connected to inlet pipes of a mixer which is located in the lower part of the body and the axial outlet pipe of which is directed either towards the bottom of the reactor or upwards, and which is equipped with a diffuser. The mixer consists either of a coaxial tube and of one or more consecutively connected coaxial vortex chambers with tangential inlet pipes, or only of two or more vortex chambers. The tangential pipes ensure an identical direction of rotation of the flows in all of the chambers. At least one of the tangential pipes is inclined in the opposite direction of the outlet opening in the axial pipe. The mixer, with the outlet pipe directed upwards, is located within a cylindrical shell which is concentric to the body of the reactor. The technical result is an increase in the intensity of dispersion of the interacting phases and in the uniformity of dispersion of the reactants in the two-phase flow formed.
