道路近傍や喫煙空間などの生活環境,微粒子を取り扱う作業環境といった比較的高濃度かつ粗粒子が多い環境も含めて試験調査を行い,円孔スペーサ径の微調整による分級特性の最適化,ベルマウス型入口ノズルの採用でさらなる低圧損化を実現した。また,実用性を考慮して前段の粗粒子除去用インパクタや,マルチノズル構造を検討し,装置が備えるべき基本構造を整えた。市場価値が十分あるとの判断を踏まえ,メーカーの協力を得て商品化を具体的に開始した。
During test of developed devices at living environments with rather high nano-particle concentration such as roadside, smoking area and working environments, we improved the inertial filter technology by precise control of separation size by careful selection of spacer size and pressure drop reduction by using bell-mouth inlet. In order to reduce dust load on the main inertial filter, a pre-separator consist of impactor and inertial filter stages was designed to use upstream part of the main inertial filter. Also, multi-nozzle inertial filter was tested to find availability of inertial filter for various flow rate with simpler structure. We started preparation for marketing of the technology with private companies.
