【摘要】：为解决现有电除尘器(ESP)体积庞大、微细粉尘去除效率低的问题,设计了一套烟气流量为3 000 m3/h的单区式双涡旋型极板电除尘器,并通过实验研究了工作电压U、有效收尘面积A、烟气流速υ以及粉尘粒径dp等因素对单区式双涡旋型极板电除尘器除尘效率的影响,同时比较了该除尘器与传统结构电除尘器在性能上的差异。实验结果表明:当工作电压U为18~19 k V、有效除尘面积A为2.7 m2、烟气流速υ为2.5~3.5 m/s时,除尘效率η可以维持在99%以上;粒径在0~10μm范围内时,尘粒的捕集效率稍低,但也能够达到93.66%。研究结果表明单区式双涡旋型极板电除尘器具有明显的技术经济优势,有望解决现有电除尘器中存在的技术问题,可为该种除尘器的工业应用和推广提供理论依据。
[Abstract]:In order to solve the problem of large volume and low removal efficiency of fine dust in existing ESPs, a single zone double vortex plate electrostatic precipitator with gas flow rate of 3 000 m3 / h was designed. The effects of working voltage, effective dust collection area A, flue gas velocity v and particle size DP on the dust removal efficiency of single zone double vortex plate electrostatic precipitator are studied experimentally. At the same time, the performance difference between this kind of precipitator and the traditional structure electrostatic precipitator is compared. The experimental results show that when the working voltage U is 1819 kV, the effective dust removal area A is 2.7 m2, and the flue gas velocity is 2. 5 and 3. 5 ms, the dust removal efficiency 畏 can be maintained above 99%. When the particle size is in the range of 0 ~ 10 渭 m, the capture efficiency of dust particles is slightly lower, but it can also reach 93.66. The results show that the single-zone double-vortex plate electrostatic precipitator has obvious technical and economic advantages, and it is expected to solve the technical problems existing in the existing electrostatic precipitator. It can provide theoretical basis for the industrial application and popularization of this kind of dust collector.
