Abstract
A particle charging device for use in a two-stage type of electric dust collecting apparatus, including opposite electrodes disposed at such positions that an intermittent ion generating zone is established between the opposite electrodes and ion generating electrodes, and that uneven, non-uniform electric fields are established between said opposite electrodes and transfer electrodes; a dust containing gas is ionized in the intermittent ion generating zone, and upon transferring the ions by means of the uneven electric field, said ions are brought in contact with a flow of particles in said dust containing gas to thereby charge said particles.
