Design method of fine dust filtering system for large underground electric facility using induced voltage electrostatic precipitating apparatus

Abstract

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.

Description

technical field [0001] The present invention relates to a design method of a filter system for supplying external air to large underground equipment, and more particularly to a design method of a high-capacity electric filter system using an induced voltage electrostatic dust collector to prevent the inflow of fine dust. Background technique [0002] Large underground equipment has grown with the development of construction projects. [0003] As the economy develops, the necessity to economically and effectively utilize urban space and the possibility of utilizing underground facilities as industrial facilities have grown, and large-scale underground facilities have been developed. [0004] In particular, underground spaces have been exploited to relieve traffic congestion and make city centers more efficient. [0005] For example, transportation-related underground facilities such as subways, tunnels, underpasses, and large-scale underground parking lots have been develope...

AI Technical Summary

Problems solved by technology

[0011] However, traditional ventilation shafts and filters are insufficient for ventilating large underground installations because traditional ventilation shafts are small and the filters interfere with air flow

[0012] Large volumes of outside air should flow into large underground installations, however, there are limitations to installing many ventilation shafts to provide sufficient air to very large underground installations, and there is limited space for filters as they act as a resistance to air flow
