  • Patent number: 8961651
    Abstract: Energy consumption of the society is increasing due to expanding economic activity and increasing population. As greater consumption of energy generates more air pollution, there is an ongoing need to find better methods of reducing pollutants in terms of effectiveness and reduced energy consumption. The solution proposed in this disclosure takes advantage of electrical characteristics such as electron affinity and dipole moment. There are many pollutants which exhibit positive electron affinity. Such a pollutant can be easily converted to a negative ion by providing an extra electron. Many of the pollutants have dipolar charge distributions which facilitate electrical interactions with charges. If one of the pollutants becomes charged, it can attract other pollutants which are dipoles to form clusters of pollutants. Furthermore, charged clusters are responsive to electric and magnetic fields. For example, they can be separated from the rest of the flue gas by manipulating with such fields.

  • Publication number: 20140283686
    Abstract: Methods using vane electrostatic precipitators collect charged and uncharged particles with vane assemblies that are physically arranged to reduce the air flow rate to at or below 1.0 ft/sec (0.305 m/sec). In preferred embodiments, the main entrained air is divided into smaller proportions by using a plurality of vane assemblies in a vane electrostatic precipitator operating at a specific angle that have discharge electrodes in front of the vanes. This results in both the particles being charged and the flow rate of the air and articles being reduced as they traverse between vanes and over the vane surface. The vane width, operating angle, vane length and vane offset are designed to reduce the air flow rate. As a result, at the ends of the vanes, a high percentage of the air flow is less than 1 ft/s.

    Abstract: An illustrative filter includes an electret material, which has a long-lasting electric charge, that is at least partially coated or covered with a conductive layer. An optional insulation layer may be disposed over at least part of the conductive layer. If the electret material has a positive charge, then the filter attracts particles with a negative charge, and vice versa. The filter adsorbs the attracted particles until it becomes saturated with particles, at which point the conductive layer is charged to have a polarity that is opposite the built-in polarity of the electret and that matches the polarity of the adsorbed particles. The charged conduction layer repels the adsorbed particles from the filter, cleaning the filter for continued use.

  • Publication number: 20120107465
    Abstract: An apparatus, system and method of using electrons to perform at least one operation are disclosed. An apparatus may include groups of carbon nanotubes capable of emitting a relatively large number of electrons for use in performing operations such as sterilization, purification, deodorization, cleaning, cross-linking, pest control, pathogen control, chain-scissioning associated with surface modification, waste treatment, etc. Each group of carbon nanotubes may be aligned with a respective opening in a member, where the member may be coupled with a membrane capable of transmitting electrons. Electrons may be emitted from the carbon nanotubes by applying a vacuum to the carbon nanotubes and also applying an electric potential between the carbon nanotubes and the member. As such, electrons from a plurality of groups of carbon nanotubes may generate an electron flow that can be used to perform one or more operations on a fluid, object, or other type of component.

  • Patent number: 8128869
    Abstract: An air sanitization system including a reactive oxygen species generator, a variable speed fan, a pathogen sensor and a controller. The reactive oxygen species generator generates reactive oxygen species from an oxygen-containing gas and discharges the reactive oxygen species to a conditioned space. The variable speed fan directs the oxygen-containing gas to the reactive oxygen species generator at a controlled speed. The pathogen sensor senses a level of airborne pathogens in the conditioned space and generates a signal indicative of the level of pathogens sensed. The controller receives the signal from the pathogen sensor and varies the speed of the variable speed fan in response to the signal to decrease a speed of the variable speed fan in response to an increase in the level of airborne pathogens sensed by the pathogen sensor.

    Abstract: An electrostatic filter assembly configured to be installed in equipment for removing particulate matter entrained within a gas stream. The filter assembly functions in the removal and collection of the particulate matter from the gas stream. The equipment for removing particulate matter includes a high voltage discharge electrode for imparting an electric charge to the particulate matter whereby an electrical field is produced at the filter assembly. The filter assembly includes a filter element and a supporting structure for the filter element. The supporting structure is configured to establish at the filter assembly, under the operating conditions of the equipment for removing particulate matter, an electrical field having an intensity that produces no more than a selected amount of degradation at the filter element during operation of the equipment for removing particulate matter. Also a method of manufacturing such an electrostatic filter assembly.

  • Publication number: 20110277632
    Abstract: Disclosed is an electrostatic aerosol concentrator for the concentration of aerosol particles and their collection for subsequent analysis. The concentrator comprises an airflow chamber that includes alternately energized and grounded electrode elements that work in concert to impart radial inward motion to charged aerosol particles and focusing them toward an enriched aerosol outlet. If desired, filtered air inlets may be used to provide a sheath of aerosol-free air along the chamber periphery and prevent deposition of particles onto electrode surfaces. Aerosol particles entering the airflow chamber may carry a positive or negative charge naturally, or a charge may be induced on the particles using a charging section located upstream of the aerosol inlet. Natural or induced charges on the aerosol particles may be used to selectively concentrate subpopulations of aerosol particles from a mixture of particles.

  • Patent number: 8012412
    Abstract: Described is an air and surface purifying device having a purifying cell structured for maximizing the realized photocatalytic reaction at a photocatalytic surface without using an additional ultraviolet bulb. The purifying cell positions at least three photocatalytic surfaces about a single ultraviolet bulb such that the photocatalytic surfaces substantially encompass the ultraviolet bulb and are saturated by ultraviolet light radiating from the ultraviolet bulb. Because the photocatalytic surfaces are saturated, the potential photocatalytic reaction at the photocatalytic surfaces is fully realized. Stated differently, the realized photocatalytic reaction is maximized. Because the purifying cell maximizes the realized photocatalytic reaction, the purifying cell maximizes the purifying capacity of the photocatalytic surface and, thus, the purifying cell itself.
