摘要

为合理选择浆液冷却烟气脱白的设计参数，评估其节水效果，对烟气湿烟羽的形成原因、影响因素及浆液冷却烟气脱白的原理进行了介绍，分析了排烟初始温度对换热器换热负荷的影响以及水温对循环冷却水水量的影响。通过脱硫系统水平衡影响因素的分析，提出了一种基于设计煤种参数、脱硝液氨耗量的脱硫系统水平衡计算方法，给出了脱硫系统水平衡工艺设计的建议，并对320MW机组烟气脱白工艺的节水效果进行了分析。结果表明，即使在40℃的极端高温天气条件下，烟气脱白的节水效率仍可高达49.0%。

Abstract

In order to rationally select the design parameters of slurry cooling flue gas de-whitening and evaluate its water saving effect. The reasons for the formation of flue gas wet plume

the influencing factors and the principle of slurry cooling flue gas de-whitening was introduced in this paper. The effect of flue gas temperature on heat exchanger heat transfer load and the effect of water temperature on circulating cooling water volume were analyzed. Based on the analysis of the factors affecting the water balance of the desulfurization system

a calculation method for the water balance of the desulfurization system based on the design coal parameters and liquid ammonia consumption was proposed. The water balance process design of the desulfurization system was given. The water saving effect of the flue gas de-whitening process of 320MW unit was analyzed. The results show that the water-saving efficiency can reach as high as 49.0% even under extreme high temperature conditions of 40℃.
