Abstract: A process is provided for conditioning fly-ash present in flue gas which also contains sulfur dioxide and steam by subjecting the fly-ash containing flue gas to ultraviolet radiation so as to convert steam present in the flue gas into hydroxyl radicals which oxidizes about 5 to 10 percent of the sulfur dioxide in the flue gas into sulfur trioxide. This photo-produced sulfur trioxide conditions the fly-ash and renders it more easily separated in the electrostatic precipitator.

Abstract: A device for the removal of microscopic particles from air includes a tube which in a certain cross-section has a replaceable, suitably ionizing particle separation unit (4) with a multitude of threads or strips (10) which are held together in a common frame structure (11) extending across the tube. The strips (10) are arranged to be set in motion in relation to each other by the passing air, thereby generating static electricity for attracting micro particles from the air to the strips. The frame structure (11) is made of a flexible band formed into loops, the strips being affixed on the band, the frame structure also including a plurality of pipe- or tubeforming members located amongst the band loops, in order to distribute the air flow through the frame structure.

Abstract: A method of separating material includes providing a mixture of a first material, such as a semiconductor, and a second material, such as an insulator or a different semiconductor. The mixture can be irradiated using a light source at a wavelength that causes the first material's conductivity to increase while leaving the second material's conductivity (substantially) unchanged. Placing the mixture in contact with a ground electrode discharges the first material but not the second material due the difference in their conductivities. Applying an electric field to the discharged mixture separates the discharged first material from the second material.

Abstract: An air purification reactor is described that has a variety of improvements. In one aspect, the air purification reactor includes an ionizer (or plasma chamber), an electrostatic filter, a photocatalyst, and a UV light source that is distinct from the ionizer. The ionizer is arranged to introduce ions into a gaseous fluid stream passing through the air purification device. The electrostatic filter is located downstream of the ionizer and is arranged to electrostatically filter particles from the fluid stream. The UV light source is positioned to subject the photocatalyst to ultraviolet light and may be arranged upstream, downstream, or intermediate the electrostatic filter. With this arrangement, the ultraviolet light that impinges on the photocatalyst causes a photocatalytic oxidative reaction to occur at the photocatalyst that is capable of reducing volatile organic compounds carried in the fluid stream. In other (separate) aspects, the reactor includes an absorber or an oxidation catalyst. Generally, the various aspects of the invention may be used separately or in combination with one another.

Abstract: An air purifier includes a vertically disposed housing provided with a wire gauze filter, electric fans and air filter elements. The electric fans draw outside air around the floor vertically into the bottom air intake port toward the top air output port of the housing so that the flow of air, when passed out of the air output port, flows upwards to a certain elevation and is then diffused and lowered in all directions around the housing. By means of the traction of the flow of air, the pressure difference of the convection of air between the low air pressure and the high air pressure at the bottom and top sides of the housing, high concentration of car waste gas, micro dust particles, hair dust, micro fibers and other harmful industrial odors that fall to the floor due to the effect of gravity or floating nearly above the floor are sucked into the inside of the housing by the low air pressure zone at the open bottom side of the housing and then removed by the filter elements.

Abstract: A system for filtering and purifying air within a closed environment. Air is drawn through a sequence of six filtration and purification stages, comprising, in order, an electrostatic prefilter to remove airborne impurities >=3 microns, an ultraviolet light source, a catalytic surface effective for breaking down hydrocarbons, a HEPA or other particulate filter for mechanically capturing airborne particles, a gas absorption filtration medium for removing volatile organic compounds and comprised primarily of activated charcoal, and an ionization module. The UV light is directed both upstream and downstream. The catalytic surface is semitransparent to UV light so that UV light strikes and kills microbes in the HEPA or other particulate filter medium.
