Abstract
Apparatus for the on-line treatment of chemical reagents, including a flow line for a reagent flow, a vortex mixer in the flow line for combining and mixing the reagent flow with at least one further reagent flow, a pulser in the flow line for causing the pulsing of the mixed flow from the vortex mixer, and a vessel having an array of vortex cells for receiving the pulsing mixed flow to cause development and growth of precipitate under narrow residence time distribution conditions. Flow lines mix a flow of reagents to initiate precipitation. The pulser pulses the admixed reagents and causes the pulsing mixed flow to swirl with a constantly reversing rotational flow to achieve development and growth of precipitate.
Claims7
An apparatus for carrying out on-line a chemical process, said apparatus comprising mixing means for mixing a plurality of chemical reagents, at least one of said reagents being a fluid, pulser means for superimposing cyclic flow pulsations upon outflow of mixed reagents from said mixing means, and a reaction chamber adapted to receive the pulsed flow of the mixed reagents, the reaction chamber comprising a series of communicating vortex cells configured to set up, in conjunction with said pulsed flow of the mixed reagents, a swirling flow in the vortex cells of the reaction chamber.
