摘要： A gas separation apparatus using electrostatic precipitators and mechanical rappers is enhanced by the addition of an opposite polarity refreshing power supply and a switching arrangement. The switching components selectively disconnect the primary power supply and connect the refreshing power supply to the electrostatic precipitator, causing an electrical impulse in the precipitator sufficient to dislodge precipitate from the collector plates. In one embodiment, an RC filter is further provided to control the impulse and reduce the burden that would otherwise be placed upon the refreshing power supply. In a second embodiment, a pair of SCR strings serve as the switches. Cleaning power is delivered from a capacitor through one of the SCR strings using a resonant circuit, the resonance which causes the SCR string to commutate off after the impulse has been delivered. The capacitor is charged to a pre-calculated potential, dependent upon a measured potential just prior to delivery of the cleaning power, to ensure that the cleaning voltage stays below a corona onset voltage. The novel separation apparatus and technique offer particular synergy when applied to the effluent stream from a coal-fired electric power plant or other similar gas streams.
摘要翻译： 使用静电除尘器和机械敲击器的气体分离装置通过添加相反极性的刷新电源和开关装置来增强。 开关组件选择性地断开主电源并将刷新的电源连接到静电除尘器，使得除尘器中的电脉冲足以从收集板上移除沉淀物。 在一个实施例中，进一步提供RC滤波器以控制脉冲并减轻另外将被置于刷新电源的负担。 在第二实施例中，一对SCR串用作开关。 使用谐振电路从电容器通过SCR串中的一个SCR串来传送清洁电力，该谐振电路在脉冲输送之后导致SCR串整流。 电容器被充电到预先计算的电位，这取决于在传送清洁功率之前的测量电位，以确保清洁电压保持低于电晕起始电压。 当应用于来自燃煤电厂或其它类似气流的流出物流时，新颖的分离装置和技术提供特别的协同作用。

摘要： A method for charging an electrostatic precipitator, powered by a power supply and having a plurality of corona electrodes and a plurality of collector electrodes, such that a precipitator capacitance may be formed therebetween, includes a storage capacitor across the power supply, having a storage capacitance. A voltage switch is capable of selectively electrically coupling the electrostatic precipitator to the storage capacitor. The storage capacitance is sufficient to charge the electrostatic precipitator to a preselected operative voltage within a rise time greater than a first preselected value and less than a second preselected value.
