Patent ID: 8002876

Claim:
A method for separating dust-particles from industrial waste gases, in which dust-particles are difficult to separate are removed from a gas fluid, wherein the dust-particles being successively ionized and separated within a high-voltage zone which comprises one or several individual ducts with the help of electrostatic charging and separation by means of only one high-voltage supply source for this high-voltage zone, and wherein the dust-particles being ionized and separated both in ionization zones as well as in separation zones of the individual ducts by connected negative electrodes which are connected to the only one high-voltage supply source, characterized in that the high-voltage zone comprises one or several individual ducts of even duct width, in which the dust-particles are successively ionized and separated, wherein the connected negative electrodes are connected with only one output of the one high-voltage supply source and wherein by suitable choice of the negative electrode geometry for the ionization zones and separation zones a substantially higher current flow is generated in the ionization zones than in the separation zones, so that in the ionizing zones a sufficient charging of the dust-particles is achieved which are then separated optimally in the following separation zones.
