Application of low-energy secondary emission electron gun for VOC treatment

Abstract

Non-thermal plasma technologies using electrical discharges or electron beam irradiation offer an energy- and cost-efficient approach to the decomposition of gaseous compounds. We have developed a low-energy secondary emission electron gun (SEEG) using wire ion plasma source (WIPS) for gaseous pollutant treatment. The devise has some inherent advantages such as compact in size, wide and uniform electron beam. In this work, divergence of electron beam energy was measured and NO removal characteristics have been studied under increasing gun voltage and changing dimension of gas treatment chamber. It has been observed that the smaller chamber gives better removal efficiency of NO and we are trying to apply this device to VOC treatment
