摘要： In an electrostatic precipitator for an electrostatic filter at least one group (11 and/or 12) of electrode or plate elements of like polarity are made of or coated with a semiconducting or dissipative material, and the electrode elements of at least one group (12) comprise or are associated with a screen (16) of an insulating material at the edge thereof which is directed against the stream (A) of air through the precipitator.

摘要： PCT No. PCT/SE95/00038 Sec. 371 Date Feb. 10, 1997 Sec. 102(e) Date Feb. 10, 1997 PCT Filed Jan. 17, 1995 PCT Pub. No. WO95/19225 PCT Pub. Date Jul. 20, 1995An air cleaning apparatus, especially for cleaning of room air, includes an ionizing device (14) having a unipolar ion source formed by a corona discharge electrode, an electrostatic precipitator (12) connected to a high-voltage source (15) and having a flow-through passageway (18) for air to be cleaned and two groups of electrode elements (16, 17) disposed in the flow-through passageway, the electrode elements (16) of one group being interleaved with and spaced from the electrode elements (17) of the other group and arranged to be at a potential different from that of the said other group. The corona discharge electrode (21) is arranged such that the ions generated at the electrode can diffuse essentially freely away from the electrode and thereby diffuse substantially freely throughout the room in which the ionizing device (14) is positioned.

摘要： A two-stage electrostatic filter includes an ionization section which is arranged in an upstream part of a throughflow passage (28) and includes a wire-like corona electrode (31) which is disposed in an ionization chamber (29) and connected to one pole of an electric high voltage source (16). The filter further includes a target electrode (21; 37) which is spaced from the corona electrode (31) and connected to another pole of the high voltage source. A capacitor separator (30) is located in a downstream part of the throughflow passage (28) and includes a first and a second group of electrode elements (32, 33) which are placed side-by-side in spaced-apart relationship. The electrode elements (32) of the first group are placed alternately with the electrode elements (33) of the second group and are adapted to lie on a potential which is different from the potential on which the electrode elements (33) of the second group lie. The ionization chamber (29) has a target electrode surface (37; 21) which is disposed both upstream and downstream of the corona electrode (31). When measured perpendicularly to the upstream-downstream direction of the throughflow passage (28) and to the longitudinal axis of the corona electrode, the distance of the corona electrode (31) from the target electrode surface is at least four times the distance between neighbouring electrode elements (32, 33). The capacitor separator (30) and the ionization chamber (29) form a disposable unit made of a non-metallic material, preferably a cellulose fibre material.

摘要： Un filtre électrostatique à deux étages comprend une zone d'ionisation qui est positionnée dans la partie amont d'un passage à travers le courant (28) et comprend une électrode-couronne (31) en forme de fil, qui est située dans une chambre d'ionisation (29) et reliée à un pôle d'une alimentation haute tension (16). Le filtre comporte de plus une électrode-cible (21; 37) qui est éloignée de l'électrode-couronne (31) et reliée à un autre pôle de l'alimentation haute tension. Un séparateur condensateur (30) est situé dans la partie aval du passage à travers le courant (28) et il comprend un premier et un second groupe d'éléments d'éléctrode (32, 33) qui sont placés côte-à-côte et espacés l'un de l'autre. Les éléments d'électrode (32) du premier groupe sont placés en alternance avec les éléments d'électrode du second groupe (33) et ils sont conçus pour être sous l'effet d'une tension qui est différente de celle sous l'effet de laquelle sont les éléments d'électrodes (33) du second groupe. La chambre d'ionisation (29) possède une surface d'électrode-cible (37; 21) qui est située en même temps en amont et en aval de l'électrode-couronne. Lorsqu'elle est mesurée perpendiculairement à la direction amont-aval du passage à travers le courant (29) et à l'axe longitudinal de l'électrode-couronne, la distance entre celle-ci et l'électrode-cible est au moins quatre fois celle entre les éléments d'électrode (32, 33) voisins. Le séparateur condensateur (30) et la chambre d'ionisation (29) constituent une unité amovible constituée d'un matériau non-métallique, de préférence un matériau à fibre cellulosique.
