Abstract:
An electrostatic filter (1) has a chamber (11) into which a gas stream is introduced. An ioniser (19) in the form of an electrode array (20) is located in the chamber (11) and creates an ionising zone through which the gas stream passes. A charged outlet (21) is located downstream from the ioniser (19). As the gas stream passes through the ionising zone, the unwanted particles therein are charged and urged away from the outlet (21) by the ioniser (19). Charged particles approaching the outlet (21) are also electrostatically repelled therefrom, permitting “clean” gas to be extracted through the outlet.
Abstract:
A collecting device for collecting particles floating in the atmosphere includes a collecting container; a pump for sucking the atmosphere into the collecting container; a discharge electrode disposed in the collecting container for generating single polarity ions to charge the particles in the collecting container; and a dust-collecting electrode for collecting the charged particles in the collecting container through a potential difference between the discharge electrode and the dust-collecting electrode. The dust on the dust-collecting electrode is measured and analyzed.
Abstract:
In a method of measuring particles floating in an atmosphere, the atmosphere containing the particles is sucked into a container, ions are generated from a discharge electrode disposed in the container to charge the particles with the ions. A dust-collecting electrode is arranged in the container to electrically conduct with a ground potential, wherein the dust collecting electrode is formed of a transparent plate having a transparent conductive film on a surface thereof facing the discharge electrode. The charged particles are collected on the dust-collecting electrode disposed in the container by using a potential difference relative to the discharge electrode, and the particles on the dust-collecting electrode are measured.
Abstract:
The present invention includes an inner electrode 6 formed inside a dielectric body 4 and a surface electrode 5 formed on a surface of the dielectric body 4, and the surface electrode 5 is formed in a grid pattern with acuminate parts 5a formed inside the grid squares. More specifically, each acuminate part 5a is made of a triangle whose vertices are two arbitrary points on a side of the grid square and an arbitrary point inside the grid square, or a quadrangle whose vertices are a crossing of grid lines, an arbitrary point near a straight line connecting crossings of grid lines in the diagonal positions, and two arbitrary points on sides of the grid square. The present invention provides an ion generating element capable of generating positive ions and negative ions in a stable manner even under a wide range of applied voltage while curbing the increase in noise, and capable of decreasing the generation of ozone, and provides an ion generator, air conditioning apparatus, cleaner and refrigerator using this ion generating element.

Abstract:
An automatic condensed oil remover for an intercooler of a diesel engine has a flow restrictor that is positioned between the intercooler and the diesel engine, an oil sump in the intercooler, and an oil tube carrying condensed oil from the oil sump to the diesel engine. The flow restrictor creates a pressure drop sufficient to force the oil to flow from the oil sump through the oil tube to the diesel engine.
Abstract:
An electrostatic precipitator has a high voltage electrode including multiple wire segments that are positioned within a surrounding electrically conductive porous media having a central axis and wherein the electrode assembly extends along the central axis. The electrode assembly has a plurality of wire lengths positioned to extend in a direction along the longitudinal axis of the porous media, and the wire segments being arranged to have a substantially longer total length than the length of extension along the longitudinal axis. An aerosol containing droplets is passed into the interior of the porous media, and across the electrode, which is charged with a high voltage. The porous media is at a substantially lower or different voltage from the high voltage electrodes. Flow of the aerosol containing particles charged by the electrode passes through the porous media to the outlet and the charged particles are precipitated by the porous media. Electrostatic shields are provided around high voltage insulators to reduce the likelihood of contamination of the insulators, which causes unsatisfactory current leakage.
Abstract:
A discharge electrode structure which is a substantially II-shaped sheet unit integrally made from one single blank sheet. The discharge electrode sheet unit includes two conductive sections connected with each other by two bridge sections at two ends. Two sides of each bridge section are formed with screw holes. Each conductive section is formed with a middle transverse bar formed with multiple perpendicular discharge needles at equal intervals. Each discharge needle has a tip. After the discharge electrode is connected with a DC high voltage power supply, free electrons are produced by discharging. The tips of the discharge needles are perpendicularly arranged at equal intervals so that ionic equilibrium can be easily achieved.

An electric dust collector that does not need an exhaust fan or special equipment for preventing dust from flying off. An incinerator is formed on a building, and a smokestack is raised so that it is integrated with the wall of the incinerator. The smokestack is formed from metallic sheeting and lined with refractories. A beam is installed over the smokestack. The beam is electrically insulated using insulatores. A discharge electrode is suspended form the beam at the center of the smokestack. The discharge electrode has many needle-like discharge pins almost in its lower half part. The negative pole of a DC high-voltage power supply is connected with the discharge electrode, while the positive pole is grounded and connected with the metallic sheeting constituting the smokestack.
