摘要

研究了用脉冲强相对论电子束(PIREB)处理二氧化硫(SO/sub 2/)。在与电子束源空间隔离的气体室内，研究了so2 /sub - 2/浓度和so2 /sub - 2/去除效率与PIREB辐照次数的关系。远处的气体室充满压力为270 kPa的干空气平衡的SO/sub - 2/气体混合物，并由PIREB (/spl sim/2 MeV， /spl sim/100 a， /spl sim/60 ns)穿过1.6 m长的大气照射。在初始SO/sub - 2/浓度为100 ppm的条件下，通过10次PIREB辐照，成功地处理了/spl sim/60%的SO/sub - 2/。SO/sub - 2/的去除率为3 ~ 37 g/kWh。我们还发现辐照PIREB会产生一定量的NO/ sub2 /。

Treatment of SO2 by pulsed, intense relativistic electron beam in distant gas chamber

Treatment of sulfur dioxide (SO/sub 2/) has been studied using a pulsed, intense relativistic electron beam (PIREB). The dependence of SO/sub 2/ concentration and the removal efficiency of SO/sub 2/ on the number of PIREB irradiation have been investigated within a distant gas chamber spatially isolated from the electron beam source. The distant gas chamber is filled up with a dry-air-balanced SO/sub 2/ gas mixture with the pressure of 270 kPa, and is irradiated by the PIREB (/spl sim/2 MeV, /spl sim/100 A, /spl sim/60 ns) passing through a 1.6-m-long atmosphere. With the initial SO/sub 2/ concentration of 100 ppm, /spl sim/60% of SO/sub 2/ is successfully treated by firing 10 shots of PIREB irradiation. The SO/sub 2/ removal efficiency has been found to be 3-37 g/kWh. We have also found that a certain amount of NO/sub 2/ is produced by irradiation of the PIREB.
