It is thus expediently provided a device in which a gas stream is passed through an electric field generated by means of a pair of electrodes forming first and second electrodes, in which the particles contained in the gas are charged and transported to or in the direction of the second electrode.
  • Such a device is particularly suitable for the separation of very small or fine particles or particles of the exhaust gas, so that the device for purifying exhaust gases can be particularly useful for the deposition of dust in flue gas of combustion plants.

  • the connection between the first electrode and coupling device is designed such that the first electrode of the coupling device is detachable or separable or detachable or disengageable.
  • the first electrode can be detached from the coupling device in such a way that expediently neither an electrical connection nor a mechanical connection exists between the first electrode and the coupling device.
  • the first electrode can thus be separated from the voltage source indirectly connected via the coupling device and be removed from the exhaust gas shaft so that a simple and convenient cleaning of the exhaust gas shaft without elements located therein is made possible.
  • the first electrode is designed as a flexible rod-shaped or tubular conductor.
  • the first electrode may thus be in other words, for example, as Wire may be formed, which may have any cross-sectional configuration. It is understood that the first electrode may also be formed as a lattice-shaped body, for example as a tubular or tubular grid body.
  • the second electrode at least partially surrounds the first electrode at a spatial distance.

  • the recess is formed on an end face of the connecting element, wherein particularly expediently on an opposite side of the connecting element, the first electrode extends away from the latter.
  • the return expands towards its distal end.
  • the return of the connecting element widens to the distal or outer end of the dacasgelements.

  • the recess may have any cross-sectional configuration, such as round or angular (polygon). Particularly advantageously, the recess has a circular cross-sectional area, so that the recess forms a conical recess.

  • the coupling portion tapers towards its distal end.
  • the outer configuration of the coupling portion is thus formed substantially congruent to the return of the connecting element.
  • a coupling section may be provided, which tapers only partially to its distal end.
  • the connecting element of the first electrode and / or the coupling portion of the coupling device are at least partially magnetically formed to attract each other.
  • the connecting element and / or the coupling section particularly advantageously has a magnetic region which attracts the magnetically attractable region of the other of the connecting element and / or the coupling section.

  • the exhaust shaft is particularly expediently part of a chimney, wherein an exhaust gas supply is provided in order to supply the waste gas to the exhaust gas, in particular smoke.
  • the exhaust gas supply can thus be designed in particular as a nozzle, T or tail.

  • the coupling device is arranged in the flow direction of the exhaust gas before the exhaust gas supply.
  • the coupling device is at least partially in the exhaust shaft and is arranged in the flow direction of the exhaust gas outside the actual exhaust gas flow.
