烟气脱硫用超大功率电子加速器引出窗的研制

The design of the extraction window of high power electron accelerator used in flue gas desulfurization

近些年来,人们越来越重视工业气体产生的污染,尤其是工业气体中硫产生的大气污染和酸雨。大功率电子加速器产生的电子束烟气脱硫工艺由于其脱硫效率高,没有二次污染而倍受关注。引出窗作为加速器的关键部件之一,其使用寿命直接影响加速器运行的稳定。本文论述了我所研制的烟气脱硫用超大功率电子加速器引出窗与其他结构引出窗相比较的优点,并详细介绍了该引出窗的选材、结构、更换以及维护等问题。

Recently, the pollution caused by industrial exhaust gas, especially, the air pollution and acid rain resulting from the sulfur of exhaust gas, is increasingly drawing people＇s attention. The flue gas desufurization by electron beam produced by high-power electron accelerator has the characteristics of high efficiency and non-secondary contamination. As one of the most pivotal part of accelerator, the service lifetime of this extraction window directly effects the stable operation of the device. In this paper, a brief review is given to summarize the advantages, material selecting, structure, replacing, maintaining of the extraction window of high-power electron accelerator developed by SINAP.
