摘要
我国西北地区部分光伏场站建设在煤矿地区,光伏组件表面煤泥类沉积物影响发电效率,高效低成本清洗是一项急需突破的技术问题。以煤矿地区光伏面板为研究对象,通过分析面板沉积的煤焦油成分,开展对其煤焦油沉积物具有针对性的新型清洗剂和清洗技术研究,结果表明:主要成分为活性生物酶、十二烷基磺酸盐与脂肪醇聚氧乙烯醚的活性清洗剂具有较好的清洗效果;活性清洗剂清洗效果甚佳,3~5 min即能清洗干净;清洗剂对组件面板、密封胶和金属框架无腐蚀影响。透光率影响结果表明,清洗后的面板玻璃的透光率提高明显,从清洗前90%提高到95%,因此高活性环保清洗剂为解决西北煤矿地区光伏组件面板清洗问题提供了方案。
Some photovoltaic stations in Northwest China are built in coal mining areas.The slime deposits on the surface of photovoltaic modules affect the power generation efficiency.Efficient and low-cost cleaning is a technical problem that needs to be solved urgently.In this paper,the photovoltaic panel in coal mine area is taken as the research object.By analyzing the components of the coal slime layer deposited on the panel.The study of new cleaning agent and cleaning technology for coal tar deposits was carried out.The results show that the active cleaning agent mainly composed of active biological enzyme,dodecyl sulfonate and fatty alcohol polyoxyethylene ether has good cleaning effect.Active cleaning agent cleaning effect is very cleaning efficiency,which can be cleaned in 3-5 minutes.The cleaning agent has little effect on the corrosion of component panel,sealant and metal frame.The results of light transmittance influence show that the light transmittance of the cleaned panel glass is significantly improved,from 90%to 95%before cleaning.Therefore,high activity environmental cleaning agent provides a solution to the problem of PV module panel cleaning in the northwest coal mining area.
