阅读：5发布：2023-02-24

专利汇可以提供Pulse-operated electrostatic precipitator专利检索，专利查询，专利分析的服务。并且An electrostatic precipitator in which the discharge electrodes thereof receive electrical pulses from a power supply. The power supply includes a source of DC (direct current) energy which feeds, in parallel, a bank of capacitors, via a plurality of diodes. Periodically the capacitors are discharged, via thyristors, into parallel primary windings of a step-up transformer whose secondary winding is connected to the discharge electrode.，下面是Pulse-operated electrostatic precipitator专利的具体信息内容。

权利要求

1. A system for transmitting controlled electrical energy pulses to electrostatic precipitator electrodes comprising a source of direct-current energy, unidirectional-current conduction means having one terminal connected to said source of direct-current energy and a second terminal, an electric-charge-accumulating means having one terminal connected to the other terminal of said current conduction means and a grounded second terminal, an electric-pulse-controlled rectifier-switching means having an input terminal connected to the junction of the terminals of said charge accumulating means and said current conduction means, a control terminal and an output terminal, means for applying electric pulses to said control terminal, a stEp-up pulse transformer having at least one primary winding connected to the output terminal of said controlled switching means and a secondary winding connected to said precipitator electrodes whereby pulses of electrical energy are applied to said precipitator electrodes, said precipitator comprising at least one discharge electrode connected to said secondary winding and one grounded collector electrode in proximity to said electrode, said unidirectional-current conduction means comprising a plurality of diodes including anodes and cathodes, means for connecting each anode, in parallel, to said source of directcurrent energy, said electric-charge-accumulating means comprising a plurality of capacitors, each of said capacitors having one terminal connected to the cathode of one of said diodes, respectively, and a second grounded terminal, said electric-pulse-controlled rectifier-switching means being a plurality of thyristors, each of said thyristors having an anode connected to the cathode of one of said diodes respectively, a gate terminal connected to said electric-pulse-applying means, and a cathode, and said pulse transformer comprising a plurality of primary windings, each of said primary windings having a first end connected to the cathode of one of said thyristors, respectively, and a second end connected to ground.

2. The system of claim 1 and further comprising means for monitoring an electrical parameter of the electric pulse applied to said precipitator to control the amplitude of the direct-current energy from said source.

3. The system of claim 1 and further comprising means for monitoring an electrical parameter of the electric pulses applied to said precipitator to control the rate of the electric pulses applied to said gate terminals.
