摘　　要：对预热器下部的煤气水封进行改造，防止氨汽冷凝液进入饱和器，同时增加母液酸度自动测量装置和自动加酸装置，稳定母液酸度，减少饱和器内的副反应，避免生成Fe(OH)3、Al(OH)3、(NH4)2Fe[Fe(CN)6]、Cu2[Fe(CN)6]等着色能力极强的副产物，减少对硫铵颜色的影响，提高硫铵质量。Modification was carried out on the gas water seal in the lower part of preheater to prevent condensed ammonia leaking into saturator, meanwhile, mother solution automatic measuring device and acid automatic charging equipment were installed additionally to stabilize mother solution acidness, to reduce the auxiliary reactions, and to prevent coproducts being produced which have extreme coloration such as Fe （OH）3, Al （OH）3, （NH4）2Fe [Fe （CN）6] , Cu2 [Fe （CN）6], etc. being produced , decreasing their effects on the color of ammonium sulfate to improve the quality of ammonium sulfate.
