摘要
探索并研究了在DBD放电间隙中添加生物质(包括工业木屑、玉米秸秆、水稻秸秆和小麦秸秆)对NO脱除效率的影响。研究结果表明:将工业木屑和3种农作物秸秆(玉米秸秆、水稻秸秆和小麦秸秆)作为添加物质放置于反应器放电的区间内,NO脱除效率为工业木屑>玉米秸秆>水稻秸秆>小麦秸秆>无填充。对工业木屑以及3种秸秆进行水热改性处理,研究改性木屑和秸秆对NO脱除效率的影响,结果表明,工业木屑水热改性处理2 h、玉米秸秆水热改性处理4 h、水稻秸秆水热改性处理2 h、小麦秸秆水热改性处理2 h对NO的脱除效率相对比较高。
The effects of adding biomass(including industrial wood chips,corn straw,rice straw and wheat straw)in the discharge area of DBD on NO removal efficiency were explored and studied.The results show that:when industrial wood chips and three kinds of crop straw(corn straw,rice straw,and wheat straw)are placed as additional substances in the reactor discharge interval,the NO removal efficiency is industrial wood chips>corn straw>rice straw>wheat straw>No filling.The industrial wood chips and three kinds of straw were hydrothermally modified to study the effect of modified industrial wood chips and straw on NO removal efficiency.The results showed that the removal efficiency of NO is relatively high when the industrial wood chips was hydrothermally treated for 2 hours,the corn straw was hydrothermally treated for 4 hours,the rice straw was hydrothermally treated for 2 hours,and the wheat was hydrothermally treated for 2 hours.
