Experimental study of hydrophobic coating on dust suppression of flat plate collector
摘要
Abstract
Dust accumulation in the cover plate of flat-panel solar collector will reduce the heat collection performance,but there are few studies on self-cleaning of the cover plate.The mechanism of particle deposition was analyzed,and superhydrophobic and hydrophobic coatings were selected for dust suppression in flat plate collector.In order to verify the feasibility and quantify the dust suppression effect of the selected coating,natural dust accumulation experiments were carried out on three sets of collectors using superhydrophobic coating,hydrophobic coating and uncoated glass cover plate in Urumqi city,and the performance parameters of each system were analyzed.The results show that the superhydrophobic coating can effectively improve the heat collection performance of the plate collector under the condition of natural dust accumulation,but the effect of the hydrophobic coated glass plate is inferior to that of the bare glass plate.After 16 days of natural dust accumulation,compared with the bare glass cover collector,the transmission ratio of the superhydrophobic coating cover collector is increased by 3.6%,the heat collector temperature is increased by 3.96%,and the heat collection efficiency is increased by 2.94%.In the 16 d overall comparison,compared with the bare glass cover collector,the transmission ratio of the superhydrophobic coating cover collector is increased by 1.66%,the heat collector temperature is increased by 4.09%,and the heat collection efficiency is increased by 2.90%.关键词
