  • Patent number: 7700051
    Abstract: An exhaust gas treating apparatus 1 includes; a case body 2 and a plasma producing means 3 capable of producing plasma inside the case body 2 and treats the substances to be treated contained in the exhaust gas by the plasma producing means 3. The plasma producing means 3 has one or more each of a pulse electrode 4 and a ground electrode 5 that are oppositely disposed in the case body 2 and has a pulse power source 6 capable of feeding a pulse current to the pulse electrode 4 by switching frequency and/or voltage for different values at predetermined time intervals. The substances to be treated contained in the exhaust gas can selectively be treated by switching frequency and/or voltage value for different values at predetermined time intervals so that plasma of a kind adequate for the substances to be treated contained in an exhaust gas is produced between the pulse electrode 4 and the ground electrode 5.

  • Patent number: 7648683
    Abstract: A plasma generating electrode 1 of the present invention includes a plurality of unit electrodes 2 hierarchically layered at predetermined intervals, the unit electrodes 2 including a deficient unit electrode 2b in which a conductive film 4 has an absent portion and a normal unit electrode 2a in which the conductive film 4 does not have an absent portion. Spaces V formed between the unit electrodes 2 include a normal space Va formed so that the distance between conductive films 4 corresponds to the distance between the unit electrodes 2 and a deficient space Vb formed so that the distance between the conductive films 4 is greater than the distance between the conductive films 4 in the normal space Va. The plasma generating electrode 1 of the present invention can efficiently treat a plurality of predetermined components contained in a treatment target fluid by utilizing different types of plasma suitable for respective reactions by causing the treatment target fluid to flow only once.

  • Patent number: 7638103
    Abstract: A plasma generating electrode 1 of the invention includes at least a pair of electrodes 5, at least one electrode 5a of the pair of electrodes 5 including a plate-like ceramic body 2 as a dielectric and a plurality of conductive films 3 disposed in the ceramic body 2 and each having a plurality of through-holes 4 formed through the conductive film 3 in its thickness direction in a predetermined arrangement pattern, the through-holes 4 having a cross-sectional shape including an arc shape along a plane perpendicular to the thickness direction, an arrangement pattern of the through-holes 4a formed in at least one conductive film 3a being different from an arrangement pattern of the through-holes 4b formed in the other conductive film 3b. The plasma generating electrode 1 is capable of simultaneously generating different states of plasma upon application of voltage between the pair of electrodes 5 due to the different arrangement patterns of the through-holes 4 in the conductive films 3.
