The underground structure ventilation system is used to circulate the air.

Recently, however, the problem of fine dust has become a serious social issue.In particular, there is a high possibility that indoor pollution will increase when tunnel air with the highest pollution level (PM10) is introduced into the history or inside the vehicle. It is difficult to filter fine dust completely with a mechanical or chemical filter provided with a conventional mechanical or chemical composition, and there are limitations due to cost problems and general problems.

In particular, when the subway stops in history and the door is opened, fine dust may rise from the underground tunnel or inside the track due to the train wind, resulting in high levels of platform dust, which are not suitable for conventional mechanical or chemical filters. not.

Therefore, compared to the conventional mechanical or chemical filter, it has a competitive advantage in cost and general problems, and restricts the effective air purification treatment according to the situation of entry, arrival and departure of the subway. Search is required.
