摘　　要：提出一种由两个等离子体发生装置串联组成的新型磁场固定串联辉光等离子体固氮装置。对该装置的固氮能耗、产物浓度、电压特性、电阻特性、电导率特性以及电场特性进行分析,并与单个装置放电情况进行对比。结果显示,串联放电装置的等离子体固氮能耗在放电电流为60mA时达到最低,为143.14GJ/tN,考虑到镇流电阻消耗的电能后,总固氮能耗最低为229.69 GJ/tN。单个装置放电时的总固氮能耗最低为370.38GJ/tN,表明串联放电有利于降低固氮能耗,且随电流增加,两者固氮能耗的差距显著加大。A novel magnetic field fixed and series on the circuit glow plasma nitrogen fixing device is developed,which consists of two plasma generator devices connected in series on the circuit.The nitrogen fixing energy consumption,product concentration,voltage characteristics,resistance characteristics,electrical conductivity charac-teristics and electric field characteristics of the device are studied,and the discharge conditions of a single device are compared.The plasma nitrogen fixation energy consumption of the series discharging device reaches the lowest at 143.14 GJ/tN when the discharge current is 60 mA.The lowest total nitrogen fixation energy consumption after calculating the electrical energy consumed by the ballast resistor is 229.69 GJ/tN.The lowest total nitrogen fixation energy consumption of a single device is 370.38 GJ/tN,indicating that series discharge is beneficial to reduce nitrogen fixation energy consumption,and the gap between the two nitrogen fixation energy consumption widen significantly with the increase of current.
