Abstract
A particle collecting device includes a vent pipe having a channel space through which air flows, a first air blower that delivers air including a particle at a first end of the vent pipe into the channel space, a collector that is disposed to block a channel in the channel space at an intermediate part of the vent pipe and that collects the particle included in the air delivered by the first air blower, and a second air blower that collects the air traveling through the collector at a second end of the vent pipe and that delivers the air outward from the channel space. The first and second air blowers operate such that a first pressure in a first channel space extending from the first air blower to the collector and a second pressure in a second channel space extending from the collector to the second air blower are maintained to have a relationship in which the second pressure<the first pressure≤atmospheric pressure. The first and second channel spaces are included in the channel space of the vent pipe.
