【摘要】 将静电喷雾技术与无人机技术相结合用于治理开放性粉尘,使用Fluent对粉尘的扩散模型进行数值模拟。模拟得出无人机工作高7m,喷雾压力为0.2MPa时,无人机静电喷雾的平均降尘效率能达到85.87%,并在自然风速为1m/s、空气相对湿度为70%时,局部区域的降尘效率高达95.93%。本文提出的无人机静电喷雾控制开放性粉尘技术降尘效果较好,对沉降重金属污染粉尘技术发展有重要意义。更多还原

【Abstract】 Electrostatic spray technique combined with UAV technology was used to treat open dust, and the diffusion model of dust was numerically simulated with Fluent in this paper. The simulation shows that the airflow generated by the rotor of the UAV at 7 m height and under the spray pressure of 0.2 MPa, the average dust reduction efficiency of the electrostatic spray of the drone can reach 85.87%. When the natural wind speed is 1 m/s, and the relative humidity of the air is 70%, the dust reduction efficiency in the local area reach up to 95.93%.The drone electrostatic spray control open dust technology proposed in this paper has good dust-reducing effect and is of great significance to the development of heavy metal pollution dust technology.更多还原
