【摘要】：ESFF(静电强化纤维过滤)复合式电袋除尘器采用一种可导电的特种滤料作为放电系统的接地极。ESFF在运行过程中会产生臭氧,进而引发纤维材料腐蚀,造成设备使用寿命缩短。实验通过模拟ESFF除尘器的基本运行状态,进行臭氧产生规律方面的研究工作。研究对比了金属接地极系统和导电滤料接地极系统的电学特性及其臭氧产生规律,并考察了过滤风速、输出功率对臭氧产生量的影响。并对实验结果进行了理论分析和模拟计算。结果表明,ESFF除尘器和传统的电除尘器中存在相同的臭氧产生规律,臭氧产生率随输出功率的增大而增大,两者近似呈线性关系。
[Abstract]:ESFF (Electrostatic enhanced Fiber Filtration) composite bag dust collector uses a special conductive filter material as the ground electrode of the discharge system. During the operation of ESFF, ozone will be produced, which will lead to corrosion of fiber materials and shorten the service life of the equipment. The basic operating state of ESFF precipitator was simulated to study the law of ozone production. In this paper, the electrical characteristics and ozone generation of metal earth-electrode system and conductive filter material earth-electrode system are studied and compared, and the effects of filter wind speed and output power on ozone generation are investigated. The experimental results are theoretically analyzed and simulated. The results show that there is the same law of ozone production in ESFF precipitator and traditional electrostatic precipitator, and the ozone production rate increases with the increase of output power, and the relationship between them is approximately linear.
