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.

A dispersion lance is for use in combination with a fluid treatment system of the type which includes a flow duct in which a fluid stream is mixed with a treating agent. The dispersion lance includes a pipe mounted in the duct with its axis approximately transverse to the direction of the fluid stream flow, the pipe having a series of openings along its length for injecting a treating agent into the fluid stream. A baffle extends lengthwise along the pipe, the baffle having a cross-section the central portion of which is V-shaped, with the apex of the V facing upstream of the fluid stream flow, and with generally flattened wing portions extending from the legs of the V beyond the sides of the pipe in a direction where they transversely intersect the stream flow. The baffle acts to generate a low pressure zone on its downstream side which enhances turbulence in the fluid. The orifices of the pipe are located to inject the treating agent into the low pressure zone to better distribute and intermix the injected treating agent into the surrounding fluid.

A venturi scrubber for scrubbing a gas stream to remove undesired gaseous and particulate components. The device includes a scrubber vessel having an external wall, an upper inlet for admitting the gas stream, and a collecting reservoir at the bottom of the vessel for collecting scrubbing liquid. An internal wall extends from the upper part of the external wall to define an axial converging passage for receiving and converging the gas stream from the inlet. An adjoined downwardly extending venturi passage receives the downwardly flowing gas stream from the converging passage, the internal wall abounding the venturi passage terminating above the liquid level at the reservoir; and an annular space is thereby defined between the internal and external walls. An outlet duct for the scrubbed gas stream intersects the annular space at the upper part of the space. The gas stream flowing downwardly through the converging passage and venturi passage is turned about the bottom of the internal wall to enter the annular space and proceed therein upwardly and exits the vessel through the outlet. A scrubbing slurry contacts the stream in the venturi passage. An annular mist eliminator is mounted in the annular space at an axial point below the outlet duct, and a gas diverter is mounted in the annular space below the mist eliminator to divert the gas stream which is turned upwardly into the annular space away from the external wall, whereby the upward flow through the annular space to the mist eliminator is rendered more uniform. Outlet compensating means may be provided in the annular space upstream of the outlet for impeding the flow of the gas stream to the outlet, thereby rendering the upward stream flow in the annular space more uniform.
