REACTOR FOR OBTAINING CHLORINE DIOXIDE SOLUTION Russian patent published in 2014 - IPC C01B11/00 

FIELD: chemistry.

SUBSTANCE: reactor for obtaining a chlorine dioxide solution with three flow chambers, located successively in vertical, separated with partitions with through channels, with branch pieces for discharge of the chlorine dioxide water solution in the upper chamber and branch pieces for supply of reagents and discharge of a reaction solution in the lower one, with a possibility of placing nozzles, for instance, Raschig rings in the middle chamber. Chambers are of a round shape with changeable curvature of an internal surface, and their volume increases from the lower to the upper one. Partitions are made in the form of a surface of a directed downward cone with rims in the base, in which radial channels from an external edge to the centre are made. The lower partition, in comparison with the upper one, is characterised by a smaller diameter and larger height of rim, a larger length and area of section of radial channels with their smaller number. A tube for connection of the chamber to external environment is located on the reactor axis. Branch pieces for supply of reagents are located in the cone-shaped part of the lower chamber and are directed tangentially to each other with displacement relative to the chamber centre.

EFFECT: invention makes it possible to ensure homogeneous distribution of a gas phase in the finished liquid solution.
