The dust collecting electrode portion (31b) is made of a plate-like member having a mesh-like structure with a plurality of pores, thereby reducing an interfacial tension between the water droplets (21a) adhering on the surface of the dust collecting electrode portion (31b) and the dust collecting electrode portion (31b). Thus, water droplets are prevented from increasing in size on the surface of a dust collecting electrode, and a decrease in the dust collection capability due to adhesion of dust or the like is reduced.

  • Patent number: 8317901
    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.

The system comprises a first mesh screen filter leading to a first chamber, in which two nozzles 10 create two separate continuous water curtains 15a, 15b which overlap when viewed in the direction of the air flow to form a combined curtain extending across the region through which the air passes. The extracted air then passes via a second mesh screen filter 11 into a second chamber 12, identical to the first chamber 9, in which two further nozzles 13 are provided which create two further water curtains 15c, 15d. The water curtains 15a, 15b, 15c, 15d cool and condense vaporized oil and grease within the air, which condensed oil and grease droplets fall with the water into a container. The main bore of each nozzle is of circular cross-section, but a profiled plate causes the resulting water curtain to have a width which is narrow relative to the diameter of the nozzle bore.

  • Patent number: 7717980
    Abstract: A contaminant extraction apparatus, systems and method for extracting contaminants, such as particles and polar molecules, from an air flow containing a contaminated gas such as air so that the contaminants are expelled from the embodiments after they are extracted. One method includes the steps of generating two electric fields in separate air flow channels separated by an extraction grid with the second electric field having a greater potential difference than the first electric field; generating a first air flow through the first air flow channel and a second air flow through a second air flow channel; dispensing charged liquid droplets into the first air flow using at least one charged droplet generator; allowing the droplets to transfer charge to those contaminants; and expelling the contaminants into the second air flow using the potential difference in the second electric field.

  • Publication number: 20100116126
    Abstract: A system is provided that prevents inhibition of adsorption of Hg and other heavy metals by activated carbon or other heavy metal adsorbent due to prior adsorption of sulfur trioxide (SO3) in an exhaust gas containing SO3. As it has been found that while SO3 is adsorbed, the adsorption of SO3 precedes the adsorption of Hg and other heavy metals onto activated carbon, a basic substance injection system is disposed along an exhaust gas flow channel at an upstream side of an activated carbon injection system, thereby attaining effective removal of Hg and other heavy metals from the exhaust gas by adsorption thereof onto surface pores of the activated carbon. The SO3 concentration after removal by basic substance conversion is computed from the SO3 concentration before removal, and the activated carbon injection rate can be controlled based on the concentration after removal.

    Abstract: A process for removing carbon dioxide from a gas stream by scrubbing the carbon dioxide from the gas stream with a mixture of ammonium and alkali carbonates such as sodium carbonate and/or potassium carbonate. Using the mixed alkali carbonate solution as the CO2 scrubbing solution offers the opportunity for both low regeneration energy and low ammonia volatility while still maintaining a high rate of CO2 hydration.

    Abstract: A portable high air volume electrostatic collection precipitator for analyzing air is provided which is a relatively small, self-contained device. The device has a collection electrode adapted to carry a variety of collecting media. An air intake is provided such that air to be analyzed flows through an ionization section with a transversely positioned ionization wire to ionize analytes in the air, and then flows over the collection electrode where ionized analytes are collected. Air flow is maintained at but below turbulent flow, Ionizable constituents in the air are ionized, attracted to the collection electrode, and precipitated in the selected medium which can be removed for analysis.

    Abstract: The present disclosure relates generally to a nonwoven filtration media comprising a bonded mix of different, discontinuous, thermoplastic resin fibers and optionally discontinuous cellulosic fibers. The nonwoven media has an advantageous combination of stiffness, foldability, efficiency and the ability to retain a fold. The nonwoven media can be thermally bonded during the production process. The advantageous combination of mechanical properties allow the disclosed nonwoven media to accept and retain folds and pleats better than some conventional filtration materials while the mix of different fibers provides desirable filtration properties.
