1. A device for collecting particles in a gaseous flow comprising:

  • a collecting chamber, comprising a tubular collecting electrode,an intake of the gaseous flow in the collecting chamber,at least one capillary tube having a first end which terminates upstream of the entire tubular collecting electrode in the direction of flow of the gaseous flow through the collecting chamber, and a second end which is configured to be connected to a liquid tank, andpolarisation device which polarizes said liquid in the capillary tube so as to make a difference in potential between the liquid at said first end of the capillary tube and the collecting electrode to cause corona discharge and spraying of the liquid by electrospray in the direction of the collecting electrode.
