Method and a reactor for mixing one or more chemicals into a process liquid flow

摘要

A method for mixing a chemical into a process liquid including: injecting the chemical into the process liquid flowing through a flow pipe; forming reaction products by a reaction involving the chemical occurring in the process flow; applying an electric field or magnetic field to a region of the flow pipe adjacent to the reaction occurring in the process flow, and suppressing the precipitation of the chemical or the reaction products on the surfaces of the pipe due to the electric or magnetic field.

主权项

1. An apparatus for mixing a chemical into a target liquid flowing through an in-line reactor, the apparatus comprising:
an injection mixer mounted to the in-line reactor and configured to introduce a chemical into the target liquid; an electrode rod in the in-line reactor and separated from a wetted wall of the in-line reactor; an electrode on or in the wetted wall, and a source of electrical energy applied to the electrode rod and the electrode, the electrode rod being configured to apply an electrical field on a wetted surface of the in-line reactor adjacent a region wherein the chemical and target liquid mix and the chemical reacts in the target liquid.
