吸收塔喷淋层设计及循环泵运行优化分析

Optimized Analysis on Designing of Spray Layer and Operating of Circulating Pump

喷淋层是吸收塔内最为核心的部件之一,喷淋层的合理设计对湿法烟气脱硫系统的整体性能起着至关重要的作用,本位通过对石灰石-石膏湿法烟气脱硫吸收塔在不同喷淋层设计条件下两种方案的初投资成本和运行成本进行比较,分析了两种方案的优缺点及脱硫效率的覆盖范围;同时,通过对某一300MW机组配套脱硫装置进行不同喷淋层组合试验,研究和分析了不同喷淋层组合运行工况对脱硫效率和脱硫运行成本的影响。

The spray layer is one of the important components of absorber. The rational designing of spray layer is vital to the integral performance of FGD. The initial investment,operating cost,desulfurization efficiency,advantages and disadvantages for limestone gypsum wet flue gas desulphurization absorber with different spray layer design were analyzed.Based on the combined test of different spraying layer,the effect of different combination of different spray layer on the desulfurization efficiency and operating cost of the 300 MW unit was studied.
