Abstract

An experimental study of the radiation, temperature, and electrical parameters of an electrodeless UV source with two mercury-argon (рAr ≈ 7.5∙10–1 Torr, рHg ≈ 0.01–0.06 Torr) quartz lamps based on a coaxial microwave discharge has been carried out. The design of a germicidal (185–280) nm spectral range UV irradiator with its disinfection of the air-aqueous environment and its main parameters are proposed. A magnetron for household microwave ovens (2.45 GHz, 1 kW) was used as a source of microwave radiation. The maximum UV radiation flux (87.2 W) was achieved at the power consumed by the magnetron from the mains Pel = 687 W. It has been established that with water cooled burners (twater = 15 °C), the power range of Pel, at which the maximum energy efficiency of the lamp and irradiator is achieved, in the indicated wavelength range is wider (up to 13 %) in range (490–720) W, than with air (tair = 23 °C) cooling with power range (490–550) W.

基于低压微波汞放电的无极紫外辐射源

采用两个汞-氩石英灯( ar≈7.5∙10-1 Torr， hg≈0.01-0.06 Torr)，对同轴微波放电的无极紫外光源的辐射、温度和电学参数进行了实验研究。提出了一种光谱范围为185 ~ 280 nm的空气-水环境消毒紫外杀菌器的设计及其主要参数。家用微波炉用磁控管(2.45 GHz, 1 kW)作为微波辐射源。在主电源磁控管消耗的功率Pel = 687 W时，紫外辐射通量达到最大(87.2 W)。已经确定，使用水冷式燃烧器(水= 15°C)，在指定波长范围内(490-720)W的Pel功率范围(高达13%)比使用空气(水= 23°C)冷却功率范围(490-550)W的Pel功率范围更宽(高达13%)。在此范围内，灯和辐照器的最大能效达到了15°C。
