[Abstract]:In recent years, with the increasingly prominent contradiction between supply and demand of energy and the worsening of environmental pollution, all over the world are trying to find "green" renewable energy, natural solar energy resources with huge reserves, green pollution-free, Many advantages, such as safety and reliability, have become the focus of human attention. The installed capacity of photovoltaic is the fastest in China. As of February 2017, the cumulative installed capacity of photovoltaic in China is as high as 77GW, which is 11.9 times of the installed capacity in 2012. The surface ash drop of photovoltaic module affects the efficiency of photo-electric conversion, and can cause "heat island effect" to damage photovoltaic panels and shorten their service life. At present, the commonly used photovoltaic cleaning methods are manual scrubbing and cleaning car washing. In the working process, a large amount of water resources are needed, the cost is high, and ice is easy to be formed in winter. This paper takes a large distributed photovoltaic power station in Wuwei as the research object. According to the special requirements of solar photovoltaic panel dust removal, a kind of double roller brush cleaning and dusting is proposed. The dry dust brush of photovoltaic module, which is combined with the dust conveyer of the outer cover and the suction fan, can be used to clean the photovoltaic panel quickly and efficiently under the condition of no water and cleaning agent, and the brushing can be self-cleaning in real time. No secondary pollution. Firstly, the characteristics, adhesion characteristics and adhesion force of dust particles are analyzed, the general cleaning methods of dust particles are introduced, and the working objects of gas path system are introduced. Then, according to the special requirements of dust cleaning on the surface of photovoltaic panels, and referring to the existing dust removal brush structure, the paper analyzes the technical characteristics of the ideal photovoltaic module dry dust removal brush itself, and determines the overall scheme. Guide the structure design of each part of dry dust removal brush. The design and selection of dry dusting brush dusting mechanism, dust conveying mechanism and dust cleaning mechanism are carried out respectively, the working principle of the dry dusting brush is introduced, and the 3D model of dry dust collecting equipment is built with the help of Creo 3D software. The driving mode of dry dust removal brush is selected. The dust removal mechanism of dry dust brush is studied systematically. Firstly, the working characteristics and structure parameter setting of dry dust collection brush are analyzed, and the influence of each structure parameter on dusting effect is analyzed. The flow field in the brush body is simulated and analyzed by fluent software. The velocity vector and pressure distribution are obtained according to the preliminary design parameters of the dust removal brush, and then the control variable method is used. The influence of the main structure parameters of dust conveying mechanism and dust cleaning mechanism on its working performance is analyzed visually. Finally, the structure parameters of the brush body are obtained by comparing the simulation results of the primary design of the brush body flow field with the optimum dust raising effect and the dust cleaning effect. It provides the basis for the final styling of brush body. Finally, according to the simulation calculation and optimization results, the dry dust brush experimental prototype is made, a large number of dust removal experiments are carried out, the dust removal effect is observed and analyzed, and the working parameters are optimized. The results show that the prototype runs smoothly. The dedusting efficiency is very high under the condition of no water and no cleaning agent, which provides the theoretical basis for the cleaning and maintenance of large-scale photovoltaic power station, and has engineering practical significance.
