Abstract

An electrostatic ionization system in a precipitation device for purifying a gas stream passing through it includes: an electrically conductive plate including a plurality of nozzles configured for passage of the gas stream; a sleeve positive-fittingly disposed on each nozzle; a high-voltage grid; a plurality of rod-shaped high-voltage electrodes each having an end connected to the grid and an exposed free end arranged identically centrally in a corresponding one of the nozzles, the electrodes each forming a circumferential gap and arranged at an electrical potential of the grid, wherein the free end of each of the electrodes is exposed downstream after the corresponding nozzle, wherein a wall of each sleeve is permeable to the gas stream and includes at least one of a grid, a perforated sheet and individual rods equidistantly spaced from each other and having free ends terminating in a holding ring.
