Electrification apparatus for electric dust collector

An electrification apparatus for dust collection, the electrification apparatus comprising:

• an electrification module configured to generate ions that are emitted to air,
• wherein the electrification module comprises:
• a high voltage tip comprising at least one discharge tip configured to emit the ions in a direction opposite to a flow direction of the air,
• a conductive plate disposed around the discharge tip and configured to generate an electric potential difference with the discharge tip of the high voltage tip,
• a lower frame that mounts the conductive plate and the high voltage tip, and
• an upper frame that is coupled to the lower frame, the upper frame covering the conductive plate and the high voltage tip so that the discharge tip is exposed to outward,
• wherein the upper frame comprises (i) an upper outer frame that provides a lower frame coupling part for coupling to the lower frame and (ii) an upper inner frame disposed inside the upper outer frame, and
• wherein the lower frame provides a coupling hook corresponding to the lower frame coupling part.
