Electrostatic precipitating apparatus and cooling tower having same

An electrostatic precipitating apparatus for a cooling tower including a heat exchanger and a water sprayer spraying cooling water to the heat exchanger, the electrostatic precipitating apparatus comprising:

• an electrostatic precipitator including a plurality of discharge electrodes to which a voltage is applied, a plurality of electrostatic precipitating electrodes each disposed between the discharge electrodes and grounded, and a setting beam having a plurality of slots at a downward side of the electrostatic precipitator into which the discharge electrodes are fixedly inserted,
• a washing water supply spraying washing water to the electrostatic precipitator;
• and
• a frame assembly supporting the electrostatic precipitator, the frame assembly including a frame extending in a stacking direction of the discharge electrodes to support the setting beam, via which a voltage is applied to the discharge electrodes,
• wherein a reinforcing rod is disposed on the discharge electrode to extend from opposite sides of the discharge electrode in a width direction of the discharge electrode such that the reinforcing rod is supported by the setting beam, wherein the setting beam include a lower beam and an upper beam coupled to the lower beam, wherein the lower beam has a bottom portion and two side walls bent from opposite side ends of the bottom portion and protruding upward, and wherein the lower slots are formed only on the two side walls.

An electrostatic precipitating apparatus for a cooling tower including heat exchanger and a water sprayer spraying cooling water to the heat exchanger, the electrostatic precipitating apparatus comprising:

• an electrostatic precipitator including a plurality of discharge electrodes to which a voltage is applied, a plurality of electrostatic precipitating electrodes each disposed between the discharge electrodes and grounded, and a first setting beam having a plurality of slots at a downward side of the electrostatic precipitator into which the discharge electrodes are fixedly inserted;
• a washing water supply spraying washing water to the electrostatic precipitator;
• and
• a frame assembly supporting the electrostatic precipitator, the frame assembly including a frame extending in a stacking direction of the discharge electrodes to support the first setting beam, via which a voltage is applied to the discharge electrodes,
• wherein a downward surface of the electrostatic precipitating electrode is provided with a lowest portion disposed below other portions of the electrostatic precipitating electrode so that the washing water is collected at the lowest portion, wherein a discharge guide having a channel is disposed directly below the lowest portion so that the washing water flowing down from the electrostatic precipitating electrode is accommodated in the channel.
