    Abstract: An electrostatic dust filter is provided utilizing a fabric filtering member. The dust particles are electrically charged and are deposited on the filter member in an electric field maintained at the surface of the filter, so that the dust particles deposit in a relatively porous layer having a low pressure drop across the filter element as compared to conventional filters.

    Abstract: An electrostatic precipitator particularly for removing dusts of high electrical resistivity from a gas stream. The precipitator includes parallel, grounded plate electrodes with high voltage corona wires suspended between the plate electrodes. Corona from the wires electrically charges the dust particles, and the electric field adjacent the grounded plates drives the charged particles onto the plates. In order to prevent the occurrence of back-corona due to high resistivity of the dust, the high voltage corona discharges are produced in short pulses with longer intervals between the pulses, and auxiliary electrodes are provided to maintain the necessary electric field during the intervals between pulses. Electrical circuits and control means are also provided for applying a high voltage to the corona wires in short pulses, and for applying a high voltage to the nondischarging auxiliary electrodes during the intervals between pulses with a low voltage on the auxiliary electrodes during the pulses.

    Abstract translation: 一种静电除尘器，特别用于从气流中除去高电阻率的灰尘。 除尘器包括平行的接地平板电极，其中高压电晕线悬挂在板极之间。 来自电线的电晕对灰尘颗粒进行电荷充电，并且接地板附近的电场将带电粒子驱动到板上。 为了防止由于灰尘的高电阻率引起的反电晕的发生，脉冲间隔较长的短脉冲产生高电压电晕放电，并且提供辅助电极以在间隔期间保持必要的电场 脉冲。 还提供了电路和控制装置，用于以短脉冲向电晕丝施加高电压，并且在脉冲期间在辅助电极上具有低电压的脉冲之间的间隔期间向非放电辅助电极施加高电压 。
