A method for designing a fine dust electric filtering system for a large underground facility using an induced voltage electrostatic precipitation device according to the present invention relates to a method for designing a large-capacity filtering system that uses the induced voltage electrostatic precipitation device so as to prevent inflow of fine dust into the large underground facility. The present invention includes a ventilation opening providing an air flow path and a filtering device. The ventilation opening is a piping-structure concrete structure that provides the flow path so that external (aboveground) air can flow in the large underground facility. The concrete structure has a horizontal section. A vertical wall with an opening/closing door is formed in the horizontal section. The filtering device is the induced voltage electrostatic precipitation device in which the fine dust is electrically charged with an induced voltage and is captured. A precipitation unit of the induced voltage electrostatic precipitation device is disposed at a back end (in the air flow direction) of the vertical wall with the opening/closing door which is disposed in the horizontal section of the concrete structure. The control unit is externally disposed to be adjacent to the concrete structure where the precipitation unit is disposed. According to this design method, the large underground facility can be used with the large-capacity induced voltage electrostatic precipitation device so as to address ventilation problems with the large underground facility. Accordingly, the ventilation problems with the large underground facility, particularly, problems with fine dust, can be addressed. Also, the method for designing the fine dust electric filtering system can significantly reduce air inflow resistance while providing high fine dust removal efficiency. |
