[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.
