Description

Slim standing type air purifier for subway platform}

The present invention relates to an air purification device, and more particularly, to a slim-type air purification device for a subway platform that is installed in a subway platform to collect and process fine dust contained in the air inside the subway platform.

In general, underground tunnels and underground platforms of subways contain large-sized exhaust fans because it is difficult to circulate air by natural ventilation, and fine dust remains in the underground space as it is, which can threaten the health of people using the subway. Underground structure ventilation system is used to circulate air.

However, recently, the fine dust problem has become an issue as a serious social problem, and there is a high concern that indoor pollution increases especially when tunnel air with the highest fine dust (PMlO) pollution enters a station or vehicle interior. However, the filtration of such fine dust is difficult to completely filter fine dust with a mechanical or chemical filter provided with a conventional mechanical or chemical composition, and there are limitations due to problems in cost and general purpose.

In particular, when the subway stops at the station and the door is opened, fine dust may rise again from the inside of the underground tunnel or track due to the train wind, and the concentration of fine dust at the platform may appear high. Existing mechanical or chemical filters are not suitable to solve this problem.

In addition, in the case of a subway platform that is already in operation, it was not possible to install a large air purification device that occupies a lot of space in the platform due to the large floating population. And, in the case of a small air purifying apparatus, the purification capacity was insufficient, so it was not enough to purify the internal space.

In particular, because the width of the platform is narrow, in the case of a thick air purification device, it interferes with the movement of passengers, resulting in a lot of congestion.

Therefore, compared with the existing mechanical or chemical filter, it is competitive in cost and general problems, and it is possible to effectively perform air purification treatment according to the situation such as entrance, arrival, departure of the subway, and the space of the subway platform. A plan is being sought to develop a slim-type air purifier that does not occupy much.
