为了建立气固流态化磁选过程中颗粒群的相互作用模型,优化了高梯度磁选设备工作参数,在单颗粒微粉煤比磁化率一定的条件下,通过对高梯度磁选中单颗粒球形微粉煤的动力学分析,建立了气固流态化分选过程中的单颗粒煤粉运动的动态数学模型;进而探索出聚磁介质当量直径的临界模型,并分析了单颗粒微粉煤被捕集到聚磁介质上时相对气体流速的运动速度。
In order to establish the interaction model of particle swarms in gas-solid fluidized magnetic separation process, the working parameters of high-gradient magnetic separation equipment are optimized. Under the condition that the specific magnetic susceptibility of single-particle fine coal is constant, single- The dynamic mathematical model of pulverized coal was established to establish the dynamic mathematical model of single particle pulverized coal in gas-liquid fluidized bed. Then the critical model of equivalent diameter of polymagnetic medium was explored. The velocity of the gas relative to the gas flow rate when it is collected on the magnetic collector.
