Abstract:
The invention relates to an emission electrode (10) for use in an electrostatic precipitator, in combination with one or more collector electrodes, wherein the emission electrode includes a carrier bar (11) and a plurality of electrode elements (12). One end-part of respective electrode elements (12) is connected to the peripheral surface of the carrier bar (11) in the absence of a gap therebetween, and in a manner such that the electrode elements will project from the peripheral surface of the carrier bar in a number of mutually different directions. The free-end or tip of respective electrode elements has a pyramidal or conical configuration (13) and the shank-part (15) of the electrode elements is advantageously screw-threaded. The end-parts of the carrier bar (11) are provided with means (16) for attachment of the emission electrode to holder devices. The inventive emission electrode is highly efficient and can be manufactured and handled in a very rational and effective manner.
Abstract:
An apparatus for removing respirable aerosols (typically within the size range of about 0.1 to about 2 microns in diameter) from air comprises a housing and a chamber demountably coupled to the housing, the chamber having a dielectric material forming a packed bed within a charged bed region and apparatus for charging the aerosols in the air so that they may be removed when contacting the dielectric material in the bed region. An indicating device is provided to signify when the dielectric material is contaminated and should be renewed. The chamber may comprise cardboard or plastic coated with a conductive material and can be disposed of along with the contaminated material.A method for removing the respirable aerosols from air is also disclosed.
Abstract:
A collecting electrode for use in wet electrostatic precipitators, the collecting electrode being fabricated from an electrically-conductive, corrosion resistant and temperature and spark resistant composite material comprising carbon fiber and thermosetting resin so as to pro\ the collecting electrode with an improved arc resistance, as dictated by erosion density and direction, by controlling the weave pattern and/or fabric thickness of the carbon fibers.
Abstract:
The present invention relates to a dust collecting filter and an electric dust collecting apparatus with the same for eliminating dust in the air, smoke that contains oil which occurs during cooking, and exhaust generated from the factories. The invention mainly comprises: a discharge electrode formed with a discharge pole from which electric charges are emitted; and a dust collecting electrode to which dust attaches thereon, wherein the dust collecting electrode is inserted into a plate and has a fixed size. With this constitution, the present invention has high purification efficiency due to the miniaturization of the invention, has strong mechanical intensity, enables repair or replacement of only a damaged part, and enables easy maintenance due to the separation of a dust collecting unit and a discharge unit. In addition, by the standardization of the dust collecting filter, a plurality of dust collecting filters or multi-layered dust collecting filters can be mounted according to installation capacity whereby said filters may be easily applied to various places and designed in larger forms. Moreover, the state of operation of the filter can be checked at all times, and the dust collecting filter and a power supply unit are switched automatically according to the opening and closing operation of a door because an electric connector is positioned on the inner side of the door.

The present invention relates to the use of corrosion, temperature and spark resistant electrically conductive components in wet electrostatic precipitator systems (WESPs). In particular, the present invention is directed to using a conductive composite material in the fabrication of wet electrostatic precipitator system components.
Abstract:
Ein elektrostatischer Abscheider zum Entfernen der festen und flüssigen Bestandteilen aus einem Aerosol, zeichnet sich durch mindestens einen Hochspannungsstab aus, der über einen abseits des Gasströmungsweges sitzenden Hochspannungsisolator in den Gasströmungsweg ragt. Der Hochspannungsisolator sitzt in einem topfartigen, vom Aerosol nicht durchströmten, an ein elektrisches Bezugspotential angeschlossenen Isolatorgehäuse. Der mit Elektroden bestückte Hochspannungsstab ragt koaxial in eine hohlzylindrische Gitter- oder Maschenelektrode, die mit einer Stirn an eine Bodenplatte für das Isolatorgehäuse angebracht und an ein Bezugspotential angeschlossen ist. Die Elektroden bilden umfänglich gleichverteilte Spaltstellen der kleinsten Weite H. Die Gitter- oder Maschendrahtelektrode stößt oder steckt in einer Düsenplatte. Die Gitter- oder Maschendrahtelektrode/n ist/sind von einem porösen Kollektor höchsten über die Hülsenlänge jedoch um den Umfang vollständig umgeben. Der gesamte Aerosolstrom muss durch den porösen Kollektor strömen.
