本研究的目的是开发一种传感器,它能够通过测量平均液滴尺寸以及液滴浓度来监测喷雾过程。为了最大限度地减少传感器对喷雾的操纵,使用了称为统计消光法的光学测量原理。传感器可以被构造成披针形,因为仅需要一个激光束来照射喷雾,并且仅需要在测量体积后面的一个位置处测量激光束的强度。因此,传感器可以仅通过一个直径约为50 mm的槽口插入喷雾塔中。激光束可以使用可适应的护套屏蔽,这可以在空间上限制测量体积。此外,传感器的光学元件可以通过在测量体积方向上流过护套的冲洗体积流来防止污染。为了证明这种测量原理适用于喷雾过程的监测,通过传感器的原型测量了不同喷雾的液滴尺寸。本文介绍了该传感器的测量原理、结构和测量结果。
The objective of this study is to develop a sensor which is able to monitor spray processes by measuring a mean droplet size as well as the droplet concentration. To minimize the manipulation of the spray by the sensor, an optical measurement principle which is called statistical extinction method is used. The sensor can be constructed lanceolate because only one laser beam is necessary to illuminate the spray, and the intensity of the laser beam has to be measured at only one place behind the measurement volume. Consequently, the sensor can be inserted in the spray tower through only one notch with a diameter of about 50 mm. The laser beam can be shielded using adaptable sheaths, which can spatially limit the measuring volume. In addition, the optical components of the sensor can be protected against fouling by a rinse volume flow through the sheaths in direction of the measuring volume.To prove suitability of this measuring principle for the monitoring of spray processes, droplet sizes of different sprays are measured by a prototype of the sensor. The measuring principle, the construction of the sensor, and measurement results are presented and discussed in this paper.
