目前预防空气中病原体传播的重要性日益凸显,寻求有效的空气消杀技术变得至关重要.上层空间紫外辐照技术作为一种高效、经济且满足"人机共存"的空气消杀解决方案,已应用于针对预防结核传播中.随着固态紫外光源的发展,新型上层空间紫外辐照系统相较于传统系统,在光源升级、光束整形、结构设计等方面均有提升.光束整形的优化可使紫外线更精准地照射目标区域,提高消毒效果.本文综述了上层紫外线辐照系统的技术原理、研发现状、应用领域,并对未来发展趋势进行了展望.
As the importance of preventing the spread of pathogens in the air becomes increasingly prominent,and it is crucial to seek effective air disinfection technology.Upper space ultraviolet irradiation technology,as an efficient,economical and"human-machine coexistence"air disinfection solution,has long been used to prevent the spread of tuberculosis.With the development of solid-state ultraviolet light sources,the new upper space ultraviolet irradiation system has made many improvements compared to traditional systems in terms of light source upgrades,beam shaping,and structural design.The optimization of beam shaping allows ultraviolet rays to irradiate target areas more accurately,improving the disinfection effect.This paper reviewed the upper space ultraviolet irradiation system,discussed the technical principles,research and development status,application fields,and forecasted the future development trends.
