【摘要】：风能作为可再生的绿色能源,是当今最具有商业价值的新型能源之一。目前应用最广泛的水平轴和垂直轴风力发电机存在诸多问题,如:噪声大、易出故障以及造成视觉障碍等等。本文基于液滴的静电雾化将风能转换为电能,在高压静电场中利用风能使得发生雾化的带电液滴移动做功来实现风能和电能的转换,这种新型发电技术具有无噪声、效率高及维护方便等等优势,具有很好的发展前景。本文的研究对象为无叶片静电风力发电技术,并基于这一研究做了以下工作:第一,对整个无叶片静电风力发电系统进行了理论分析。第二,通过Simion仿真软件仿真分析了单喷嘴电极结构参数及喷嘴结构参数对液滴雾化效果的影响,得出了对液滴雾化效果影响最小的最佳电极结构参数。第三,通过Simion仿真软件仿真分析了多喷嘴在平板电极内、多喷嘴在单个柱形电极内及多喷嘴在多个柱形电极内的非线性效应,得出了不会发生非线性效应的静电雾化多喷嘴结构。第四,通过搭建静电雾化系统实验平台对不同类型的液体对液滴雾化效果的影响进行了验证,同时通过实验雾化效果图片和数据验证了前面章节仿真的正确性。本文研究成果将可作为基于液滴静电雾化的风力发电技术的参考资料,具有一定的参考价值,同时也为以后在相关技术的其它方面的进一步研究提供了理论依据。
[Abstract]:Wind energy, as a renewable green energy, is one of the most commercially valuable new energy sources. At present, the most widely used horizontal and vertical axis wind turbines have many problems, such as high noise, easy fault and visual obstacle, and so on. In this paper, based on the electrostatic atomization of liquid droplets, the wind energy is converted into electric energy. In the high voltage electrostatic field, the atomized charged liquid droplets are moved to do the work to realize the conversion of wind energy and electric energy. This new generation technology has no noise. High efficiency and convenient maintenance and other advantages, has a good prospects for development. The research object of this paper is the blade-free electrostatic wind power generation technology, and based on this research, the following work has been done: firstly, the whole blade-free electrostatic wind power generation system has been analyzed theoretically. Secondly, the effects of single nozzle electrode structure parameters and nozzle structure parameters on droplet atomization were analyzed by Simion simulation software, and the optimum electrode structure parameters with minimal effect on droplet atomization were obtained. Thirdly, the nonlinear effects of multi-nozzles in plate electrodes, multi-nozzles in a single cylindrical electrode and multi-nozzles in multiple cylindrical electrodes are analyzed by Simion simulation software. The multi-nozzle structure of electrostatic atomization without nonlinear effect is obtained. Fourthly, the effects of different types of liquids on droplet atomization are verified by setting up the experimental platform of electrostatic atomization system. At the same time, the correctness of the simulation in the previous chapter is verified by the images and data of the experimental atomization effect. The research results in this paper can be used as reference materials for wind power generation technology based on droplet electrostatic atomization, which has certain reference value. At the same time, it also provides a theoretical basis for further research in other aspects of related technologies in the future.
