Abstract
In order to ensure the bright effect of airport navigation lights, dry powder cleaning technology was adopted in this paper to improve the efficiency of removing sticky dirt on the lamp surface. The atomization scheme by mixing dry powder with water was designed through deliberately selecting the appropriate injection nozzle structure to reduce impact of powder pollution on the environment. Both simulation analysis and experimental testing showed that the overall cleaning effect and the atomization scheme were feasible, which reduce the dust pollution by more than 90%.
Highlights
In recent years, with rapid development of the aviation industry, the time for cleaning and maintenance of navigation lights at the airport has become shorter and shorter
The dry powder cleaning method is adopted for research and application
Gao et al [3], Cheng [4] used dry powder cleaning technology successively to study the effect of dry powder cleaning navigation lights
Summary
With rapid development of the aviation industry, the time for cleaning and maintenance of navigation lights at the airport (as shown in Fig.1) has become shorter and shorter. Hu Weiwei [1] from Xiamen University of Technology used solid carbonate powder as the cleaning medium, commonly known as a dry powder, and optimized the cleaning parameters. Wang et al [2] studied the cleaning effect of dry powder cleaning technology on airport. Gao et al [3], Cheng [4] used dry powder cleaning technology successively to study the effect of dry powder cleaning navigation lights. Dust and other issues exist in the process of cleaning, this paper is to investigate the cleaning equipment by optimizing water atomized parameters, aiming at improving the airport navigation lights with high cleaning efficiency. It is to reduce the harm of dust to the human body in dry powder cleaning
