Electrostatic precipitator integrated with double-skin facade of building

An electrostatic precipitator integrated with a double-skin facade of a building, the precipitator comprising:

• an outer window (12) installed at an outdoor side of the building by being made of an outer glass window frame (121) and an outer glass (122);
• an outer upper opening (14) and an outer lower opening (16) installed at upper and lower portions, respectively, of the outer window (12) for indoor ventilation;
• an inner window (22) providing a hollow layer (C) between the inner window (22) and the outer window (12) by being installed at a room side facing the outer window (12) at a regular interval by being made of an inner glass window frame (221) and an inner glass (222);
• an inner upper opening (24) and an inner lower opening (26) installed at upper and lower portions, respectively, of the inner window (22), for ventilation;
• at least one discharge electrode (31) charging particles introduced into the hollow layer (C) through the outer lower opening (16) by being installed in the hollow layer (C) and by being controlled to an appropriate voltage strength according to external wind pressure and fine dust concentration;
• and
• dust collecting electrodes (32) precipitating charged particles by being installed in contact with the hollow layer (C) on surfaces, respectively, of the outer glass (122) and the inner glass (222).
