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 photo-electronic air purifying disinfector firstly filters out airborne impurities using a washable filter screen. It then utilizes an activated carbon filter to filter out airborne bacteria and germs. The bacteria and germs which are capable of passing through the activated carbon filter are then eliminated by extreme-UV light emitted by extreme-UV light tubes. It also utilizes a negative ion generator to boost the level of anions in the air before being discharged. These two modes operate in the following manner: the first mode involves cathodic high-voltage output that is discharged via a carbonized fibre. The ionized air is then expelled by a fan. The second mode eliminates bacteria, germs and mould from air as it passes extreme-UV light tubes by exposure to extreme-UV light emitted by these extreme-UV light tubes.
Abstract:
An airplane air purifier employs high voltage electrostatic ionic air charging grid and precipitator plates for the removal of particulates and contaminants, together with germicidal capabilities provided by an ultraviolet wavelength band UVC illuminator within the purifier. The purifier is adapted to operate from the aircraft passenger cabin electrical supply or alternately from replaceable or rechargeable batteries. The purifier provided with one or more nozzle adapters to removably and supportively install the air purifier to the typical varieties of aircraft passenger air vent nozzles. The air purifier is small in size and light in weight so as to be easily carried onboard the flight and installed without issue to the air vent nozzle, whereby the air purifier purifies the ducted cabin air in the plane before diffusing into the passenger's breathing air space.

The enhancing units are adapted to be connected to the basic purification unit in a fully modular manner.
Abstract:
Cost-effective and efficient filtration technology is disclosed by which airborne pollution and contaminants are significantly removed from air circulated through furnaces and/or air conditioning systems in residential dwellings. Filters comprising both an anti-microbial ultra-violet lamp, for irradiation of airborne viruses and bacteria, and an electrostatic filter pad for trapping and holding other airborne particles are disclosed.
Abstract:
A system and corresponding methods for purifying and removing contaminants from gaseous fluids includes a housing including an inlet, an outlet, and an elongated UV chamber disposed within the housing. The UV radiation source is disposed longitudinally within the UV chamber. At least one baffle structure is disposed at an upstream location within the housing to restrict flow as well as to generate a turbulent flow of the gaseous fluid within the UV chamber. In addition, a fan is disposed at a selected location within the housing to facilitate a flow of the gaseous fluid through the housing at a selected flow rate. The dimensions of the UV chamber and UV source and the configuration of the baffle structure are selected to increase the exposure time and mixing of fluid flowing through the UV chamber as well as increase the proximity of the flowing fluid to the UV source.
Abstract:
A process and apparatus for reducing particulate, nitrogen oxides ("NOx"), sulfur dioxide ("SO.sub.2 "), and mercury ("Hg") emissions from the combustion exhaust of fossil fuel fired plants while producing an end product that is commercially useful, comprising the steps of oxidizing Hg, NOx and SO.sub.2 using a barrier, pulse, corona, or electron beam electrical discharge apparatus (100) to produce HgO and the acids HNO.sub.3 and H.sub.2 SO.sub.4 collecting the HgO, acids and particulates in a wet ESP (120), and separating the particulates from the collected acid mixture, then separating and concentrating the acids for industrial use.
