研制了一种新型的颗粒给料系统，该系统能够以低而稳定的给料速率连续分配分散的颗粒。该喂料机是基于一个旋转刷，不断清洁出口孔在料斗充满颗粒。该系统专门设计用于研磨和筛分至小于150μm的生物质颗粒，作为实验室规模气溶胶流反应器的原料。该原料通常含有大部分高纵横比颗粒，其在许多常规进料系统中形成障碍物。除生物质外，该喂料机还成功地喂料了所有经过测试的小于150μm的颗粒。在0.75slpm的恒定载气流量下，用喷雾干燥的藻类获得了4.25至2420 mg/min的进料速率，并且已经证明了用磨碎的柳枝稷的稳定和一致的进料。本文介绍了供料系统的设计、结构和初步试验情况。
A novel particle feeding system capable of pneumatically dispensing dispersed particles at low and consistent feed rates has been developed. The feeder is based on a rotating brush that continually cleans the outlet orifice in a hopper filled with particles. The system was designed specifically for biomass particles that have been milled and sieved to less than 150μm as a feedstock for laboratory scale aerosol flow reactors. This feedstock often contains a large fraction of high aspect ratio particles that form obstructions in many conventional feeding systems. In addition to biomass, the feeder has successfully fed all particles less than 150μm that have been tested. Feed rates varying from 4.25 to 2420mg/min have been obtained with spray dried algae at a constant carrier gas flow of 0.75slpm, and steady and consistent feeding with milled switchgrass has been demonstrated. The design, construction, and preliminary testing of the feeding system are presented in this paper.
