1000MW级机组电袋复合除尘特性三维数值模拟研究
Three-dimensional Numerical Simulation of Collection Properties of a 1000MW Electrostatic-fabric Integrated Precipitator
摘要
Abstract
Models of a 1000MW electrostatic-fabric integrated precipitator (EFIP) were simulated by fluid numerical simulation software based on the standardκ-ε two-equation turbulence model. The results of numerical simulation matched well with experimental data, which proved the effectiveness of the numerical simulation results. The impacts of gas volume, pressure drop and ratio resistance were studied on the dust removal efficiency. The main conclusions were as follows: the dust removal efficiency decreased with the increase of the amount of flue gas emission. In order to ensure the collection efficiency and high service life of the filter-bags, it is suggested that the flue gas volume of a single precipitator should not exceed 2300km3/h. Dust removal efficiency increased with the increase of the pressure drop. Pressure drop range should be about 1100Pa. Dust removal efficiency decreased with the increase of the ratio resistance of the dust. For the collection of dusts of high ratio resistance, the ratio resistance should be as low as possible. In other words, it is better to make the temperature as low as possible. 126℃ around is the optimum temperature range.关键词
