摘要：

基于纳米材料悬浮液的雾化法，设计一种流量和质量浓度可调节的碳纳米颗粒气溶胶制备系统。该系统将洁净的空气与碳纳米管材料分散液喷雾混合在不锈钢雾化室中，得到不稳定的气溶胶，配合嵌入式温控系统、流量控制系统和质量浓度控制系统，使不稳定的气溶胶在加热膨胀室中恒温加热，膨胀并达到均匀，通过控制可调开度的阀体得到较为稳定均匀的纳米颗粒物气溶胶流。试验表明，在温控系统表现理想的情况下，设计流量与设定流量的最大误差为9.312 mL/min，设计质量浓度与设定质量浓度的最大误差为0.206 mg/m³，基本可以产生流量和质量浓度相对稳定的纳米颗粒气溶胶。

Abstract:

A carbon nanoparticle aerosol preparation system with adjustable flow rate and mass concentration was designed based on the atomization method of nanomaterial suspension. The clean air and carbon nanotube material dispersion were sprayed and mixed in a stainless steel atomizing chamber to obtain an unstable aerosol. With the embedded temperature control system, flow control system and mass concentration control system, the unstable aerosol could be heated at a constant temperature in expansion chamber. Then the unstable aerosol expanded rapidly and reached uniformity. A relatively stable and uniform nanoparticle aerosol flow was obtained by controlling the valve body with an adjustable opening. It was demonstrated by experiments that under the condition of ideal temperature control system, the maximum error between the flow rate and the set value was 9.312 mL/min, and the maximum error between the mass concentration and the set value was 0.206 mg/m³. Nanoparticle aerosol with stable flow and mass concentration was generated basically.

Key words: engineering nanoparticle, aerosol, preparation method, flow control, mass concentration control
