摘要
A method and device for removing solid or liquid particles contained in suspension in a gas stream by an electric field, wherein the gas stream flow is directed past ion sources which simultaneously act as field electrodes. The suspended particles are thereby changed in a bipolar manner, such that approximately half of the particles are positively charged and the other half negatively charged, and are forced by the electric field to migrate across the gas stream into a preferred neutralization zone where they are concentrated, discharged, partially agglomerated and coagulated. Subsequently, the particle-enriched and particle-depleted partial gas stream thus formed are separated and treated further in accordance with operating requirements. Thereby the remaining gas stream maximally loaded with particles is fed into a particle-removal device where their withdrawal occurs. The device results in a considerable reduction in the gas volume carried along up to the fine-cleaning stage, and a decrease in cost of the electrofilter by a factor of two or more.
