Device and method for treating high-voltage pulses in the annular clearance

摘要

The device for treating a pumpable medium by high-voltage pulse, comprises a treatment room with a cross-section (9), which comprises first radius around a central longitudinal axis, a first electrode surface (3) and a second electrode surface (4), which are axially spaced apart before the first electrode surface, where an insulator (2) is arranged between the first electrode surface and the second electrode surface. The first and the second electrodes surface are suppliable with electrical energy of opposed polarity. A rod-shaped element (5) is arranged into the treatment room. The device for treating a pumpable medium by high-voltage pulse, comprises a treatment room with a cross-section (9), which comprises first radius around a central longitudinal axis, a first electrode surface (3) and a second electrode surface (4), which are axially spaced apart before the first electrode surface, where an insulator (2) is arranged between the first electrode surface and the second electrode surface. The first and the second electrodes surface are suppliable with electrical energy of opposed polarity. A rod-shaped element (5) is arranged into the treatment room, which limits the cross-section by its second radius. The first and the second electrode surface are extensively closed, and are arranged in a first radius around the central longitudinal axis. The rod-shaped element is the insulator. The first and the second electrode surface are arranged in the second radius of the rod-shaped element. The first and/or the second electrode surface is contacted by a line, which is guided by the wall of the pipe section. The device is arranged in a distance to the first and/or second electrode surface of an electrical contact surface in an axial pipe section in which the electrode surface is arranged. The first electrode surface proportionate and/or the second electrode surface proportionate is arranged into the first radius and is proportionately arranged into the second radius of the rod-shaped element. The first electrode surface is arranged in the first radius around the central longitudinal axis between the proportion of the first electrode surface and the proportion, which is arranged in the second radius around the central longitudinal axis. An electrical conducting connecting piece is fixed. The distance is larger than the distance of the proportionate first electrode surface of the proportionate second electrode surface in the second radius in which the proportionate first electrode surface of the proportionate second electrode surface is arranged into the first radius. A flow channel of the pipe section is formed whose inner radius is the first radius, and the rod-shaped element, which is axially arranged in the longitudinal central axis of the pipe section and has its surface of the second radius around the central longitudinal axis. The first radius changes itself in sections along the longitudinal center axis. The second radius changes itself in sections over the longitudinal center axis. An independent claim is included for a method for high-voltage pulse treatment of pumpable media by moving a medium.
