DESIGN METHOD OF FINE DUST FILTERING SYSTEM FOR LARGE UNDERGROUND ELECTRIC FACILITY USING INDUCED VOLTAGE ELECTROSTATIC PRECIPITATING APPARATUS

摘要

Provided is a design method of an electrical fine dust filtering system for a large underground facility using an induced voltage electrostatic precipitating apparatus, the electrical fine dust filtering system has an airshaft providing an air flow path and a filtering apparatus having a precipitator and a controller to supply outer air into a large underground facility after filtering the outer air, the airshaft is formed of a pipe structural concrete construct which provides a flow path to supply outer air into the large underground facility. The concrete construct includes a horizontal section having a vertical wall with a shutter door. The filtering apparatus having the precipitator and the controller is formed of a induced voltage electrostatic precipitating apparatus which charges and collects the fine dust by induced voltage. The precipitator is installed behind the vertical wall and the controller is installed at an exterior site adjacent to the concrete construct having the precipitator.
