Reactor with cold turning plasma and stream forcing

A plasma reactor configured to form a plasma in a flowing fluid, the reactor comprising:

• a first electrode and a second electrode connected to a source of alternating voltage and configured to create electric arcs between the first and second electrodes to generate a plasma in the flowing fluid and a portion of a vessel delimiting a reaction chamber that contains the plasma,
• wherein the first electrode comprises a central rod on a central axis of the reactor, where the rod is enveloped with an insulator, except for a downstream end in a fluid flow direction that projects from the insulator and a connection region thereof,
• the second electrode comprises a tubular body surrounding the insulator and having a discharge end in the reaction chamber,
• the reactor includes a conducting control disk having a front face linked to the downstream end of the central rod of the first electrode,
• the reactor further comprises a permanent magnet juxtaposed against a back face of the control disk,
• one or more grooves or ribs are on a front face of the control disk according to a pattern in relief and configured to define successive electric arc starting points distributed around the central axis of the reactor so as to generate electric arcs that define a reaction cone and that turn around the central axis, and
• the reactor has a cylindrical space configured to accommodate the flowing fluid between the tubular body and the insulator, and into which the fluid enters and exist within the reaction cone.
