Dust collection sheet and electrostatic precipitator

A dust collection sheet comprising:

• a plurality of first electrodes extending in a first direction, wherein each first electrode of the plurality of first electrodes comprises:
• a first electrode layer configured to receive a first voltage;
• and
• a first dielectric layer covering a portion of the first electrode layer;
• a plurality of second electrodes, wherein each second electrode of the plurality of second electrodes comprises:
• a second electrode layer configured to receive a second voltage;
• a second dielectric layer covering a portion of the second electrode layer;
• and
• a discharge portion comprising a portion of the second electrode layer that is not covered by the second dielectric layer;
• and
• a plurality of third electrodes, wherein each third electrode of the plurality of third electrodes comprises:
• a third electrode layer configured to receive a third voltage;
• a third dielectric layer covering a portion of the third electrode layer;
• and
• a corresponding portion comprising a portion of the third electrode layer that is not covered by the third dielectric layer,
• wherein each second electrode of the plurality of second electrodes is adjacent to a first electrode of the plurality of first electrodes in a second direction,
• wherein the corresponding portion of each third electrode of the plurality of third electrodes faces the discharge portion of a second electrode of the plurality of second electrodes,
• wherein each third electrode of the plurality of third electrodes is adjacent to a second electrode of the plurality of second electrodes in the first direction,
• wherein the second voltage is different from the first voltage, and the third voltage is different from the second voltage, and
• wherein the plurality of second electrodes and the plurality of third electrodes are configured to cause a charging action to occur with the discharge portion for each respective second electrode of the plurality of second electrodes.
