Abstract: A dispersion apparatus for dispersing a treating agent into a fluid treatment system that includes a flow duct in which a fluid stream flowing through the duct is mixed with the treating agent. The apparatus is based on a multi-pipe lance positioned in the stream flow, where each pipe supplies a minimum of feed discharge nozzles (typically one to four), and the individual pipes branch off from the same location. Use of the multi-pipe lance, in combination with a suitable baffle, results in better overall dispersion/distribution of the injected medium by surface area. By improving the surface area distribution, better utilization of the injected sorbent can be achieved. The baffle acts to generate a low pressure zone on its downstream side and creates a high-intensity turbulence plume in the fluid. The orifices of the pipe are located to inject the treating agent into the turbulence plume to better distribute and intermix the injected treating agent into the surrounding fluid.

Abstract: A flow control device that is uniquely capable of providing uniform flow under changing environmental conditions of temperature and pressure. The device achieves flow rate stabilization by taking advantage of the properties of the moving fluid in a channel with eddy currents that are generated as fluid moves past obstacles located in the fluid flow path. The shape and magnitude of such eddies depend on the viscosity of the fluid. Additionally, the device can also simultaneously stabilize the fluid flow rate under varying pressure by using a strategically positioned, yieldably deformable elastomeric membrane. Therefore, the invention uniquely combines two devices into one novel fluidic device that can stabilize a flow rate under simultaneously changing temperatures and pressures.

Abstract: Interaction between two different species of particles in a fluid stream is promoted by generating turbulent eddies in the fluid stream. The turbulent eddies are designed to be of such size and/or intensity that the two species of particles are entrained into the eddies to significantly different extents. Consequently, the different species of particles follow different trajectories, and the likelihood of collisions or interactions between the particles is increased. Optimum collision rates will occur for a system which maintains a Stokes Number (St) much less than 1 for one species, and or order 1 or greater for the other species. The invention has particular application in air pollution control, by promoting agglomeration of fine pollutant particles in air streams into larger particles to thereby facilitate their subsequent removal from the air streams.
