  • Patent number: 10995018
    Abstract: The invention relates to a device (10) for treating a liquid with a plasma, wherein the device (10) has a high-voltage electrode (20) as well as a liquid-permeable ground electrode device (30). The ground electrode device (30) has a flat, conductive region (32) and a porous region (34) arranged on the flat, conductive region (32), wherein the conductive region (32) is liquid-permeable along its flat extension. A discharge space (40) is formed between the ground electrode device (30) and the high-voltage electrode (20). A first dielectric (50) is arranged on the high-voltage electrode (20) so that a plasma can be generated in the discharge space (40) by means of a dielectric barrier discharge. Moreover, the device (10) has an initial flow volume (60) into which the liquid (12) can be conducted, and that is surrounded by a wall (62).

  • Patent number: 9233328
    Abstract: A cyclone separator has a cyclone arrangement with individual cyclones each provided with a cell tube and guide device. The guide device causes a gas stream passing through the cell tube to rotate. At least one particle discharge is positioned perpendicularly to a longitudinal axis of the cyclone separator and discharges separated particles that have been separated from the gas stream in the cyclone arrangement. The cell tubes, for a targeted discharge of the separated particles, each have at least one particle outlet opening that is facing the particle discharge. The particle outlet openings of at least some of the individual cyclones, neighboring each other in the direction of a first perpendicular line that is perpendicular relative to the longitudinal axis of the cyclone separator, are displaced relative to each other in the direction of the longitudinal axis of the cyclone separator.
