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.

在研制的装置在路边、吸烟区、工作环境等纳米颗粒浓度较高的生活环境中进行试验时，通过精心选择隔离片尺寸，精确控制分离尺寸，采用钟口进气道减小压降，改进了惯性过滤技术。为了减少主惯性过滤器的粉尘负荷，设计了一种由冲击器和惯性过滤级组成的预分离器，利用主惯性过滤器的上游部分。此外，还对多喷嘴惯性滤波器进行了测试，以获得结构简单、适用于不同流量的惯性滤波器。我们开始准备与私营公司进行技术营销。
