| 摘 要： | 利用单相喷嘴雾化测试系统对压力式喷嘴的雾化特性进行试验研究。采用高速动态摄像仪与扇形排状量筒结合计算机图像处理技术对液滴粒径分布、径向喷淋密度分布和雾化角等进行了测量和数据处理,得到喷嘴的雾化压力与雾化液滴粒径、径向喷淋密度分布及雾化角之间的关系。对于HHSJ-90210异型雾化喷嘴,当压力范围为0.05～0.5MPa时,雾化液滴的SMD平均粒径范围为0.831～1.621mm,条件雾化角为70.4°～91.2°;对于内螺纹喷嘴,当压力范围为0.07～0.52MPa时,雾化液滴的SMD平均粒径范围为2.23～3.52mm,条件雾化角范围在64.5°～78.5°。研究结果可为湿法烟气脱硫技术中此类型压力式喷嘴的选型提供科学依据。

| Abstract: | By utilizing a single-phase nozzle atomization testing system, an experimental study was conducted of the atomization performance of a pressure type nozzle. In conjunction with a computer-based image processing technology, a high-speed dynamic video camera and sector-shaped measuring flasks in a row were used to measure the liquid droplet diameter distribution, radial sprinkling density distribution and atomization angle, etc. with relevant data processing being performed. As a result, the relationship betw... |
