摘　　要： 水煤浆是一种煤基代油燃料 ,精细水煤浆作为水煤浆中的精品 ,在家用取暖锅炉中燃用将成为现实。本试验以管式电除尘为基础 ,模拟烟气并进行单元电除尘试验 ,通过 - 特性曲线确定管体为直径 30 mm、有效长度 2 0 cm的不锈钢管 ,电晕线为 0 .5 mm的圆形不锈钢线 ,确定二次工作电压为 7.5 k V;通过单元试验 ,确定流量为 2 5 L /min时烟尘的驱进速度为 11.16 cm /s;以试验结论为依据进行小型管式电除尘器的设计 ,在烟气排放量为 12 3m3/h,烟气浓度为1.16 g/m3时 ,需单管 5 6根 ,其外形尺寸为 2 2 .4 cm× 2 5 .6 cm× 2 0 cm,运行耗电量为 0 .2 0 k W·h。 Coal water slurry(CWS)is an alternative to fuel oil,and ultra clean micronized coal water slurry(UCMCWS),a premium one which will be used for an oil desinged residence heater.A tube electro static precipitator was exerted for experiment on simulated flue gas.On account of characteristic curve of V 1,the inner diameter of precipitation tube was 30mm,its effective length was 20cm,and diameter of corona wine was 0.5mm,which were made of stainless tube.And the secondary working voltage was 7.5kV. On unit experiment particulate velocity was 11.16 cm/s at flow rate of 25 l/min.Based on the experiment data,a small tube ESP was designed for the heater from which 123 m 3/h gas emitted at particulate concentration of 1.16g/m 3.The precipitator was composed of 56 stainless tubes,outside dimension of a tube was 22.4cm×25.6cm×20cm.The power consumption was 0.20kW·h.
