    Abstract: An ionizing particulate scrubber is provided for the removal of particulate from a gaseous exhaust stream, said scrubber including two sections: a charging section and a collection section. The charging or ionizing section includes one or more cylindrical tubular ground chambers each with a rigid threaded rod electrode extending through the center thereof. A transformer/rectifier (T/R) is provided to supply high voltage DC power to the electrode such that the cylindrical tubular ground chambers act as the ground to enable a corona to form on the threaded rod electrode. As the gas stream passes through the current flowing from the electrode to the cylindrical tubular ground chambers walls, the particulate contained within the stream is electrostatically charged. The collection system includes either a fixed or fluid bed packed section which is constantly irrigated from above. Ground rods in the packing and liquid sump allow the entire section to act as a grounded collector for the charged particulate. The gas stream and charged particulate are immediately sent from the charge section to the collection section of the system, and clean gas is then passed through an entrainment separator section to remove liquid droplets.

    Abstract: An electrostatic instrument for measuring particle concentrations and possibly sizes in aerosols, such as an Electrostatic Low Pressure Impactor or Differential Mobility Analyser suffers from errors which limit the useful response bandwidth of the device. The invention minimises or eliminates these transient errors which are caused by changing particle concentrations in the aerosol. A system may be added to an otherwise conventional instrument to compensate for the transient effects based on a model of the charge production mechanism. Alternatively, a screening electrode placed over the sense electrodes in the instrument, and held at controlled electrical potential difference, is added to the instrument to eliminate the effect. A third embodiment adds compensating electrodes which provide a direct measurement of the transient effect which can be subtracted from the signal.

    Abstract: An electro-kinetic electrostatic air conditioner includes a self-contained ion generator that provides electro-kinetically moved air with ions and safe amounts of ozone. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays. Preferably the first array comprises one or more wire electrodes spaced staggeringly apart from a second array comprising hollow nullUnull-shaped electrodes. Preferably a ratio between effective area of an electrode in the second array compared to effective area of an electrode in the first array exceeds about 15:1 and preferably is about 20:1. An electric field produced by the high voltage pulses between the arrays produces an electrostatic flow of ionized air containing safe amounts of ozone. A bias electrode, electrically coupled to the second array electrodes, affects net polarity of ions generated. The outflow of ionized air and ozone is thus conditioned.

    Abstract: An electro-kinetic electrostatic air conditioner includes a mechanism to clean the wire-like electrodes in the first electrode array. A length of flexible Mylar type sheet material projects from the base of the second electrode array towards and beyond the first electrode array. The distal end of each sheet includes a slit that engages a corresponding wire-like electrode. As a user moves the second electrode array up or down within the conditioner housing, friction between slit edges and the wire-like electrode cleans the electrode surface. The sheet material may be biasedly pivotably attached to the base of the second electrode array, and may be urged away from and parallel to the wire-like electrodes when the conditioner is in use. Another embodiment includes a bead-like member having a through opening or channel, through which the wire-like electrode passes. As the conditioner is turned upside down and rightside up, friction between the opening in the bead-like member and wire-like electrode cleans the electrode surface. The bead-like member may be made of ceramic, glass, or even metal. The through channel may be symmetrically formed in the bead-like member, but preferably will be asymmetrical to create a mechanical moment and increased friction with the surface of the wire-like electrode being cleaned.

    Abstract: Apparatus for charging and collecting submicron particles. The particles are charged by a needle-to-plate ionizer having offset rows of needles which are spaced from the plate such that voltage gradients of 6 KV/cm and higher are achieved. Needle-to-needle spacing and effective area of the plate are such that a corona current having a density of at least 4 ma/m.sup.2 flows between the needles and the plate. Charged particles are collected in a collecting section having a deflector electrode and a pair of collecting plates. The deflector electrode includes a conductor embedded in a dielectric material having a dielectric constant greater than 1, which dielectric material suppresses arcs between the deflector electrode and the collecting plates. Baffles are provided to collect efficiently and with low pressure drop those charged submicron particles not collected on the collecting plates.
