【摘要】：在自主研制的电袋复合除尘器实验台上研究了工作电压、气流温度和入口粉尘质量浓度对除尘性能的影响,探讨了除尘效率和被捕集粉尘粒径范围等的变化规律.结果表明:工作电压增大时,总除尘效率提高;气流温度超过130℃时,总除尘效率明显降低;入口粉尘质量浓度增大到14.7g/m3以上时,静电除尘区除尘效率大幅下降;静电除尘区主要除去10μm以上粒径粉尘,而布袋除尘区除尘范围偏向10μm以下的细小颗粒;在实际运行过程中,适当提高工作电压以及降低烟气温度和入口粉尘质量浓度,将有助于提高除尘效率和PM2.5的捕集率.
[Abstract]:The effects of working voltage, air flow temperature and inlet dust mass concentration on the dust removal performance were studied on a self-developed electric bag composite precipitator test bench. The variation rules of dust removal efficiency and particle size range of the arrested dust were discussed. The results show that when the working voltage increases, the total dust removal efficiency decreases obviously when the air temperature exceeds 130 鈩，
