冷却预处理器对烧结烟气温度影响仿真研究

Study on the influence of cooling pre-processor to the sintering flue gas temperature

由于烧结烟气温度很高，导致脱硫效率下降．漩涡撞击法脱硫设置了冷却预处理器，降低了烟气温度．本文采用Fluent软件对冷却预处理器运行机理进行模拟仿真，并用MATLAB拟合其规律．结果表明：冷却预处理器喷水量越大，烟气温度越低，当喷水速度大于30m／s时，随着喷水量增大，温度变化不明显，最佳喷水速度范围为25～30m／s．

Because of the high temperature of sintering flue gas, the efficiency of desulphurization was reduced. Cooling pre-processor was set up in vortex collision FGD, and the flue gas temperature was reduced. Fluent was used to simulate the function of the key components： cooling pre-processor and vortex collision components and MATLAB was used to fit out their rules. The results showed that. the greater the amount water spray from cooling pre-processor, the lower the temperature of the flue gas; and when the velocity was larger than 30 m/s, as the increasing amount of water-jet, the temperature did not change significantly, the best range of water-jet velocity was 25-30 m/s.
