摘要:
本文在提出气–固–液三相协同性分析的基础上，研究了内外增湿配比对脱硫效率的影响，确定了在60%~75%的增湿配比范围内，能够尽量兼顾单纯塔内增湿与塔外增湿方式各自优点，优化整体脱硫反应过程，有效减轻粘壁，在脱硫效率与减轻粘壁之间达到一种兼顾平衡，在不增加脱硫剂和工艺水量的前提下，能够促进脱硫反应的进行，提高脱硫剂的利用率及脱硫效率，有利于脱硫反应系统稳定、高效、经济的运行，使气–液–固三相达到较好的协同性。
In making the gas-solid-liquid phase analysis, based on the collaborative study of the internal and external humidification ratio of desulfurization efficiency, determined in 60% to 75% ratio of humidification within the tower to try to take into account the simple with the tower inside the humidifier way their advantage, optimizing the overall desulfurization reaction, effectively reducing the sticky wall, stick in the desulfurization efficiency and reduce the wall to achieve a balance between the balance, without increasing the sorbent and process water, under the premise can pro-mote the desulfurization reaction, improve the desulfurization sorbent utilization and efficiency, help desulfurization reaction system is stable, efficient and economic operation, the gas-liquid-solid three-phase to achieve better synergy.
