The invention provides a rotating disc type dust aerosol generating device characterized in that an agitating motor is controlled by a computer to drive an agitating blade in a flowing chamber to rotate, and dust in the flowing chamber is uniformly agitated and conveyed to a pit which is arranged on a rotating disc below a drain hole on the bottom of the flowing chamber and specially used for carrying dust; and dust stored in the pit on the rotating disc is absorbed into a dust spray dissolution cavity by a negative pressure generator which is controlled by the computer through a negative pressure dust suction pipe, and dust aerosol is formed and then conveyed into an aerosol detection laboratory chamber to be detected and experimented. When the agitating motor controlled by the computer rotates at different rotating speeds and uses rotating discs of different pit widths, the quantity of dust conveyed to the negative pressure dust suction pipe is different, and the concentration of dust aerosol formed by dust flowing in the dust spray dissolution cavity is also different. Therefore, dust aerosol of stable concentration can be continuously, accurately and quantitatively generated by selecting a rotating disc of proper pit width and proper rotating disc rotating speed and remaining unchanged.

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.
