热射流融除冰装置的设计与试验研究

Design and Experimental Study on Rapid Thermal Jet Deicing Device

快速、经济地清除机场跑道、城市道路、桥面的积冰积雪是冰雪气候条件下保障交通畅通与行车安全的一个重要课题。在分析研究现有除冰方法不足的基础上,提出了热力水射流方法。文章设计了热力水射流融冰装置,并对射流压力、喷嘴孔径、靶距、射流喷嘴入射角等与除冰效果有关系的因素进行了理论研究与试验分析。经过相关的试验研究表明:装置可以有效地实施除冰作业,满足设计要求,可为后续学者开展相关研究提供有力参考。

Determining how to quickly and economically remove the ice on the airport runways,city roads and bridges is becoming an important topic to keep the traffic flow and safe in the snow and icy weather.Based on the analysis of current researches on different deicing methods,a new method which combines the thermal water-jet cutting with the mechanical-milling deicing technology is presented in this paper.Factors which have effects on de-ice have been researched and experimentally analyzed,such as the jet pressure,nozzle aperture,standoff,jet injection angles,etc.After the relevant experimental research,it shows that the device can effectively implement the de-icing operation and meet the design requirements.
