低压紫外线灯在通风消毒中的应用

Application of Low Pressure Ultraviolet Lamp in Disinfection of Ventilation

生物气溶胶是细菌病毒在空气中传播的一大隐患,为了减少人类呼吸空间空气的污染,需对空气进行消毒。紫外消毒是一种广谱、高效的杀菌消毒因子,目前已经广泛应用于空气消毒,普遍应用的紫外消毒器件为低压紫外线杀菌灯,这种杀菌灯有效率高、无二次污染、广谱杀菌、无刺激性气味等优点。运用低压紫外灯的消毒仍存在较多的不确定因素。本文对低压紫外灯在空气中的应用,特别是对在有通风通道条件下的应用环境,进行了通风条件下紫外灯性能的梳理,以及合理的通风风道中紫外灯排布、设计的建议,提出目前紫外灯在通风通道中消毒存在的不足以及未来的研究方向。

Bioaerosol is a hidden danger of bacterial virus spreading in the air.In order to reduce the air pollution in human breathing space,it is necessary to disinfect the air.UV disinfection is a broad-spectrum and efficient sterilization and disinfection factor.At present,it has been widely used in air disinfection.The commonly used UV disinfection device is low-pressure UV sterilization lamp.This kind of sterilization lamp has the advantages of high efficiency,no secondary pollution,broad-spectrum sterilization,no pungent smell and so on.There are still many uncertain factors in the disinfection of low-pressure UV lamp.Here,this paper combs the performance of UV lamp under ventilation conditions for the application of low-pressure Uv lamp in the air,especially for the application environment under the condition of ventilation channel,and puts forward suggestions on the reasonable arrangement and design of UV lamp in the ventilation channel,and puts forward the shortcomings of UV lamp disinfection in the ventilation channel at present and the research direction in the future.
