Spray Configurations for Dual Chamber Mixing Devices

A treatment apparatus for a mixing device having a concentric barrel configuration, the treatment apparatus comprising:

• a manifold including an input end and an output end, a first fluid bore and a second fluid bore being formed into the input end of the manifold;
• a substantially tubular outer conduit body having a manifold end and a nozzle end, the manifold end being connected to the output end of the manifold, the outer conduit body including:
• a plurality of outer nozzles disposed in an annular pattern at the nozzle end of the outer conduit body opposite the manifold;
• a plurality of outer fluid conduits disposed within the outer conduit body, each of the outer fluid conduits being in fluid communication with both the second fluid bore and one of the plurality of outer nozzles;
• at least one outer conduit passage formed within the outer conduit body, the at least one outer conduit passage being in fluid communication with both the first fluid bore and at least one of the plurality of outer nozzles;
• wherein the first fluid bore and the at least one outer conduit passage define at least a portion of a first fluid pathway formed between the input end of the manifold and one of the plurality of outer nozzles, and the second fluid bore and each of the plurality of outer fluid conduits define at least a portion of a second fluid pathway formed between the input end of the manifold and one of the plurality of outer nozzles,

A method of treating a mixing device having an inner barrel and a concentric outer barrel, the method comprising:

• providing at least one treatment apparatus, each treatment apparatus comprising:
• a manifold having an input end and an output end, a first fluid bore and a second fluid bore formed into the input end of the manifold;
• and
• a conduit body with a manifold end connected to the output end of the manifold, the conduit body including at least one nozzle at a nozzle end of the conduit body opposite the manifold end, at least one fluid conduit providing fluid communication between the second fluid bore and the at least one nozzle, and at least one conduit passage providing fluid communication between the first fluid bore and the at least one nozzle;
• wherein the first fluid bore and the at least one conduit passage define a first fluid pathway formed between the input end of the manifold and the at least one nozzle, and wherein the second fluid bore and the at least one fluid conduit define a second fluid pathway formed between the input end of the manifold and the at least one nozzle;
• feeding a first fluid into the first fluid bore such that the first fluid flows along the first fluid pathway and is expelled through the at least one nozzle;
• feeding a second fluid into the second fluid bore simultaneous to feeding the first fluid into the first fluid bore such that the second fluid flows along the second fluid pathway and is expelled through the at least one nozzle simultaneously with the first fluid;
• and
• disposing the at least one nozzle within at least one of the inner barrel or the outer barrel of the mixing device.
