Abstract: A reactor (110) serves to combust residual carbon in fine particulate matter, remove a contaminant from fine particulate matter, or change the composition of fine particulate matter. The reactor output is processed by particle collection devices (115, 125, 140, 155, 175) and heat exchangers (135, 150, 165) to provide particle outputs (118, 124, 131, 144, 159) of different sizes. A contaminant, such as carbon or a metal, is combusted, vaporized, volatized, broken down, or substantially appears on one particle output (144) so that another particle output and the exhaust gas (142) are substantially contaminant-free. Different outputs can also be selectively mixed, as desired, to product a combined output (171). Fly ash and silica fume can be processed separately or together to reduce the amount of unburned carbon in both. Metals can also be removed from the fine particulate matter. Kaolin can also be processed to produce metakaolin.

Abstract: The present disclosure generally relates to cyclonic separation or filtering of nanoparticles suspended in a gas. A plume of liquid droplets may be generated using an ultrasound or other generator. The gas may be mixed with the plume of liquid droplets, which may have received an electrostatic charge prior to mixing, to promote preferential adhesion of the nanoparticles to the liquid droplets. The gas with suspended nanoparticles and suspended liquid particles may flow through a cyclonic separator that spins rapidly, causing the cleaned gas to flow out of the filter while the liquid with adhered nanoparticles may be discharged, collected, and/or re-used in the plume generator. By causing nanoparticles to adhere to larger liquid particles, the filter may allow the filtering and collection of much smaller particles than current systems may filter under atmospheric pressure.

Abstract: This invention relates to a wet type centrifugal ‘filter less’ air cleaner. The air cleaner includes a housing having a scrubbing room associated with an air inlet and a vortex room associated with an air outlet. A reservoir is in fluid communication with the housing for supplying washing water to the air cleaner. An atomizer is in cooperation with the reservoir for producing atomized washing water to form a wet air mixture in the scrubbing room so that the atomized washing water collects the contamination in the air. A centrifugal impeller is disposed in the housing for drawing in air to create a centrifugal force on the wet air mixture. As the wet air mixture flows through the vortex room the centrifugal force separates the contaminated washing water from the purified air because of the difference between the specific gravities of the air and the washing water.

Abstract: An air filter baffle unit that works with large type canister wet/dry type vacuums. The baffle unit also can be used in large air filter systems and can be ganged to increase filtering. The baffle unit has two sections that are connected for use. An inlet pipe is connected to the inlet of the vacuum.

In this baffle unit, there is no need for paper or other types of filters that must be periodically replaced. In this way, the baffle unit provides a simple, effective mechanism for filtering air using the wet/dry vacuum. The baffle unit can be also placed in an air filtering system that has a housing, an inlet and an outlet.

Abstract: This invention is directed to a cyclonic vapor/liquid contacting device and distillation or related mass transfer or heat transfer processes employing its use, such as fluid catalytic cracking. Liquid feed is introduced near the floor of the cyclone via downcomer or plenum. Vapor enters through sieve holes in the bottom of the cyclonic device. Near the floor are angled tabs or vanes that impart a spin to the vapor rising up through the floor. The tabs or vanes mix the liquid and vapor. The liquid is then thrown toward the cyclone wall, where it exits through slots in the wall. A second set of tabs or vanes, located about in the middle of the cyclone, imparts additional spin to the vapor and entrained liquid rising through the cyclone. This improves liquid collection by the cyclone, especially in cases where a heavy liquid load dampens the spin action of the vapor in the base of the cyclone.
