研究了球形难熔固体粒子在液相中运动,因阻力系数不同分成3个区域的2个临界直径:d12=0.917(υ2·ρι/△ρ)1/3;d23=32.3(υ2·ρι/△ρ)1/3.推导了熔体绕流球形固体粒子的传质系数:在第一区(Stokes区),kM1=0.878(△ρ·D2/ρι·υ)1/3;在第二区(过渡区),kM2=2.22(△ρ·D4/ρι)(1/d 1/2);在第三区(Newton区),kM3=3.34(△ρ2/ρι)1/8(υ1/12·D 2/3/d 5/8.相应3个区难熔球形固体粒子溶解时间是:τ1=0.57(Cs-C)·ρs/(C*-C)D 2/3·(υ/ρ2ι·△ρ)1/3·d;τ2=0.23(Cs-C)·ρs/(C*-C)D 2/3(1/ρ5ι·△ρ)1/6·d3/2;τ3=0.1(Cs-C)·ρs/(C*-C)D 2/3·(1/ρ7ι·△ρ·υ2/3)1/8·d 13/8.讨论了石灰与增碳剂溶解时间简便计算式,非球形难熔固体粒子溶解时间计算式和增碳剂最大粒度问题.
