在热丝型金属热扩散单柱上进行了氢同位素分离研究。热扩散柱基本参数如下: 柱有效长度 4890mm热丝(Cr20Ni80)直径φ0.7mm,φ0.4mm冷壁管(1Cr18Ni9Ti) φ18mm×2mm冷却水套(无缝钢管) φ80mm×5mm热丝加热方式直流分离对象 HD混合气用热丝加热伸长的方法确定了电功率与热丝温度的工作曲线。用含氘7%的混合气在热扩散柱上进行了平衡时间实验,实验表明平衡时间约9 h。在此基础上研究了不同压力和不同温度对分离度的影响。实验表明分离度随着柱压
Hydrogen isotope separation studies were carried out on a hot filament metal thermal diffusive single column. The basic parameters of the thermal diffusion column are as follows: column effective length 4890mm hot wire (Cr20Ni80) diameter φ0.7mm, φ0.4mm cold wall tube (1Cr18Ni9Ti) φ18mm × 2mm cooling water jacket (seamless steel pipe) φ80mm × 5mm hot wire heating DC separation Object HD mixture with hot wire heating elongation method to determine the electric power and hot wire temperature curve. Equilibrium time experiments were carried out on a thermal diffusive column with a mixed gas containing 7% deuterium. The experiment shows that the equilibrium time is about 9 h. Based on this, the effects of different pressures and different temperatures on the resolution were studied. Experiments show that the resolution varies with the column pressure
