原煤脱硫模型仿真与实验研究

Simulation and experiment of coal desulfurization model

搭建了介质阻挡放电脱硫模型,在此基础上,通过仿真分析了影响脱硫放电效果的介质种类、介质厚度、气隙间距、电源电压、电源频率等因素,确定了各因素的最佳配合方案。对介质阻挡放电原煤脱硫实验数据进行了处理分析,发现实验结果与仿真结果基本一致。通过对比分析放电电流频谱图和Lissajous波形,做出进一步推论:加煤能提高放电功率,介质阻挡放电对原煤的脱硫效果体现在低次谐波上。

A new coal desulfurization model of dielectric barrier discharge was built, and based on it, factors impacting on effect of desulfurization discharge, including dielectric types, dielectric thickness, gap spacing, supply voltage, power frequency were analyzed by simulation. The best fit solution of various factors was confirmed. Experimental data of coal desulfurization of dielectric barrier discharge was processed and analyzed, and it was found that the experimental results were consistent with the simulation results. Further inferences were made through comparative analysis of the discharge current spectrum and Lissajous waveform： discharge power can be improved through adding of coal; coal desulfurization effect of dielectric barrier discharge is reflected in low-order harmonics.
