SBIR Phase II: Counterflow Supersonic Virtual Impactor for Separating Fine Particles from Gases

9403683费尔德这项第二期SBIR项目是为了有效地收集和分离载气气流中的超细颗粒。拟议的工艺应根据这些超细颗粒的大小对其进行分类和分离。它使用超音速射流将颗粒带到气体逆流区域，在那里颗粒凭借它们的动量分离成收集区域。建议的方法将允许分离和收集燃烧或其他合成方法产生的纯固体颗粒，包括那些导致高气体温度的方法。如果成功，这一工艺的商业应用范围将从颗粒收集、燃烧合成到更换过滤器、旋风分离器或除尘器。

9403683 Felder This Phase II SBIR project is for the efficient collection and separation of ultra-fine particles from carrier gas streams. The proposed process should classify and separate these ultra-fine particles by their size. It uses a supersonic jet to carry the particles to a gas counterflow region where the particles separate into a collection region by virtue of their momentum. The proposed method would permit the separation and collection of pure solid particles resulting from combustion or other synthesis methods, including those resulting in high gas temperatures. The commercial applications of this process, if successful, would range from particle collection from combustion synthesis to the replacement of filters, cyclones, or precipitators.
