| 摘 要： | 本文讨论优化双室四电场电除尘器(ESP)所配套的16台中荷(ZH)三相高压电源和低压振打系统实现电除尘节能和减排。在16台传统单相高压电源供电下,电除尘出口PM10和PM2.5的排放分别为63 mg/m3和23.9 mg/m3,对应的高压一次电耗为1225 k V·A。采用16台ZH三相高压电源改造后,电除尘出口PM10和PM2.5的排放分别为10~16 mg/m3和2.0~2.5 mg/m3,对应的高压一次电耗为900~1050 k V·A。在同样高电压电耗下,PM10和PM2.5分别下降了78%和92%。 |

| Abstract: | This paper discusses the optimization of 16 high-voltage power sources for the four-field electrostatic precipitator to achieve energy saving and fly ash emission reduction. With 16 traditional single-phase rectifier-transformers (T/Rs), the PM10 and PM2.5 emissions and the primary power consumption are about 63 mg/m3, 23.9 mg/m3 and 1225 kV·A, respectively. After retrofitting the power sources with 16 ZH type three-phase T/Rs, the PM10 and PM2.5 emissions and the primary power consumption are about 10-16 mg/m3, 2.0-2.5 mg/m3 and 900-1050 kV·A, respectively. For a similar primary energy consumption, emissions for PM10 and PM2.5 are reduced by about 78% and 92%, respectively. |
