- 出版タイプ： AM金沢大学理工研究域地球社会基盤学系大気中環境ナノ粒子の特性や発生源情報を変質が少ない状態で評価できるツールである慣性フィルタ技術をベースにして、その高精度化，高速化，耐粉塵負荷特性向上を目指した技術開発と応用を行った。分級径が接近した前段インパクタとメッシュ積層慣性フィルタを組み合わせたシングルノズル構造複合型慣性フィルタを試作し，シャープな分級と低圧損を実現できることを示した。また，これをマルチノズル化することで大流量化可能なことを示した。さらに、耐粉塵特性を向上させるためマルチサイクロンと組み合わせたPM0.13分級ユニットを携帯型エアサンプラ用に試作して，環境ナノ粒子中の化学成分の時間変動評価を行った。A multi-nozzle layered mesh inertial filter was investigated in an attempt to improve the steepness of the separation efficiency curve by combining the inertial filter and an impactor. In this system, the separation curves overlap each other. Such a combination, which we refer to as a “hybrid inertial filter” was far validated for a single nozzle geometry, was scaled up using a multi nozzle geometry to a high volume air sampling flow rate. An air sampling unit designed for a commercial portable high volume air sampler, consisting of a multi-cyclone and a hybrid inertial filer, was devised. The scale up of the hybrid inertial filter using multi-nozzle geometry was confirmed. A sampler with the above sampling unit was successfully applied to evaluate various chemicals in ambient PM0.13 in a road tunnel collected at every 2-hrs. evaluated by the present unit was found to be in good agreement with values obtained for 2 different types of cascade air samplers.研究課題/領域番号:15K12185, 研究期間(年度):2015-04-01 - 2017-03-31
