【摘要】 本文对大型燃煤电站电袋复合除尘技术进行了全面的研究,如气流组织最优方案确定、脉冲喷吹系统选型及参数优化、粉尘荷电对滤料阻力的影响及高压电源的优选等。研究表明对电袋复合除尘器来说,袋式除尘区采用阶梯式布置是一种较为理想的气流组织方式,活塞式脉冲阀具有更好的清灰性能,粉尘的荷电有助于减小除尘设备的阻力,三相电源的性能优于单相电源。更多还原

【Abstract】 The comprehensive research on electrostatic fabric hybrid dust collector for large—scale coal—fired power plants has been studied in this paper,such as the establishment of optimized gas distribution,sizing and parameter optimization of pulse—jet system, the influence of charged dust on the pressure drop of filter material and the selection of high—voltage power supplies,etc.The research results demonstrated that for the electrostatic fabric hybrid dust collector.Split—level arrangement in the bag filter area is an ideal model of gas distribution.Piston type of pluse valve has a better cleaning performance.The charged dust help to reduce the pressure drop of the hybrid dust collector and the perform- ance of three—phase power supply is superior to single—phase power supply.更多还原
