Electrification apparatus for electric dust collection

An electrification apparatus for dust collection, comprising:

• an electrification module configured to generate an ion that is emitted to air,
• wherein the electrification module comprises:
• at least one discharge tip configured to emit the ion in a direction opposite to a flow direction of the air;
• at least one tip holder supporting the discharge tip;
• a conductive plate configured to generate a potential difference with the discharge tip;
• and
• a frame that defines an appearance of the electrification module and that supports the tip holder and the conductive plate,
• wherein the frame comprises an upper frame disposed at an upper side of the conductive plate and a lower frame disposed at a lower side of the conductive plate,
• wherein the tip holder is disposed between the upper frame and the lower frame, and
• wherein an upper surface of the tip holder is coupled to the upper frame and a lower surface of the tip holder is coupled to the lower frame.
