摘　　要：光伏工程中太阳能电池板积灰问题,一直是光伏工程的一大弊病,为了解决电池板积灰问题,研究了压缩空气的除尘能力。首先根据颗粒黏附理论和流体力学,建立了灰尘颗粒在气场中受力模型,并结合实际电池板表面灰尘颗的物性参数,得出三种清理模式下,除尘所需压缩空气流速与灰尘颗粒的半径、粘附力的关系。结果表明利用压缩空气除尘所需流速范围在5~80m/s,清理流速与灰尘颗粒半径成反比。其次设计了除尘实验,进行实验验证。实验结果表明,利用压缩空气除尘实用有效,能达到较好的除尘效果。In the photovoltaic engineering, the problem about dust accumulation of solar panel is always a major disadvantage. In order to solve this problem, the dedusting ability of compressed air was researched. Firstly, accord- ing to the theory of particle adhesion and fluid mechanics, the force model of dust particle in aura was built. Mean- while, combined with the physical parameters of dust particles on the surface of actual solar panel, the relation between the compressed air velocity required by dust removal and the radius and adhesion of dust particle based on three kinds of cleaning modes was obtained. The result shows that the velocity range required by compressed air dust removal is 5 ~ 80m/s. The cleaning current Velocity is inversely proportional to the radius of dust particle. Secondly, the dust removal experiment was designed for the experiment. The experimental results show that it is a practical ef- fective method to use compressed air to remove dust, which can achieve better dust removal effect.
