Abstract:
1. In combination with a fluid treatment system which includes a flow duct in which a fluid stream flowing through the duct is mixed with a treating agent; a dispersion apparatus for dispersing the treating agent into said fluid stream, comprising: a dispersion lance mounted in said duct with its axis approximately transverse to the direction of the fluid stream flow, said lance having a treating agent feed section, and a plurality of parallel pipes extending from said section, each said pipe having one or more feed discharge nozzles along its length for injecting the treating agent supplied to said pipes into the fluid stream; a baffle extending lengthwise along the upstream side of said lance, said baffle being of a uniform cross-section along its length, the cross-section having a V or a rounded first portion the convex surface of which faces upstream of the fluid stream flow, and with generally flattened wing portions extending from the lateral edges of the said first portion to beyond the sides of the multiple pipes where said wing portions transversely intersect the stream flow; the said baffle acting to generate a low pressure zone on the downstream sides of the pipes which enhances turbulence in the fluid; and wherein the discharge nozzles of said pipes are located to inject said treating agent into the said low pressure zone to better distribute and intermix the injected treating agent into the surrounding fluid stream.
