微波热风技术在艾萨炉电收尘中的半工业化研究

摘要

For the technical requirements of ISA furnace ESP system of the factory in Yunnan,the medium-test have been carried out to investigative the effect of microwave power and the temperature of microwave heating sample on the temperature of incubator. The results revealed that increasing the microwave power and microwave heating temperature can improve the temperature of incubator. The optimum conditions were identified to be microwave power of 9 kW, temperature of microwave heating sample of 760 ℃, fan voltage of 220 V, the air volume of 410 m3/h. The temperature of microwave heating sample can reaches 258℃after 15 min heat transfer, higher than requirements of ISA furnace ESP system of the factory in Yunnan, can meet the needs of industrial applications and it can achieve industrial applications.%针对云南某厂艾萨炉烟气电收尘设备对保温箱温度的技术要求,在前期小实验基础上进行半工业化试验,研究微波功率和初始微波加热体温度对保温箱平衡温度的影响.结果表明增大微波功率和初始微波加热体温度能显著提高保温箱平衡温度,在控制控制微波功率9 kW,微波加热体初始温度760℃的条件下,打开循环风机,风机电压220 V,风量为410 m3/h,经15 min传质换热后,保温箱温度达到258℃,高于云南某厂艾萨炉烟气露点温度,能满足工业应用需求.
