Zusammenfassung:To provide a technology of a classification apparatus (virtual impactor) that is light-weighted at a level where it can be mounted on a small unmanned aircraft (UAV) and can process a large volume of atmospheric air.SOLUTION: A classification apparatus 1 comprises: a sealed container 10; an inflow port 22 that is provided in the container or inside the container; a classification tube 30 that is provided on the air flow downstream side of the inflow port inside the container, has the same central axis as the inflow port, and has a tapered part the diameter of which is reduced in a direction from upstream to downstream; a large-particle side outflow port 42 that is provided on the air flow downstream side of the classification tube inside the container and has the same central axis as the classification tube; a small-particle side outflow port 51 that is provided on the air flow downstream side of the inflow port in the container or inside the container; a large-particle side suction device 43 that is provided outside the container and communicates with the large-particle side outflow port; and a small-particle side suction device 52 that is provided outside the container and communicates with the small-particle side outflow port.SELECTED DRAWING: Figure 6 【課題】小型無人航空機(UAV)に搭載可能なレベルの軽量、かつ、大容量の大気を処理可能な分級装置(バーチャルインパクタ)の技術を提供する。【解決手段】分級装置1は、密閉された容器10と、容器または容器の内部に設けられた流入口22と、容器の内部において流入口の気流下流側に設けられ、流入口と同一の中心軸を有し、上流から下流方向に直径の減少するテーパ部を備えた分級管30と、容器の内部において分級管の気流下流側に設けられ、分級管と同一の中心軸を有する大粒子側流出口42と、容器または容器の内部において流入口の気流下流側に設けられた小粒子側流出口51と、容器の外部に設けられ、大粒子側流出口に連通する大粒子側吸引装置43と、容器の外部に設けられ、小粒子側流出口に連通する小粒子側吸引装置52と、を有する。【選択図】図6
