摘要

对影响工业锅炉湿式钙法脱硫系统运行中结垢、堵塞等问题进行探讨

并作了具体的量化计算

得出了pH值的应控范围。为控制吸收液pH值

可在系统中安装智能在线 pH值控制仪 ;另外

在系统中可增设一重力脱水箱

利用其中的粉尘将系统产生的固体物质过滤掉

进一步确保系统不结垢、堵塞。实践表明

所研究的防垢防堵方案是可行的

Abstract

An approach to problems of scaling and clogging etc. which affecting the operation of wet calcium flue gas desulfuration （FGD） facility for industrial boilers has been carried out

and concrete quantitative computation being made

obtaining the range of pH value having to be controlled. In order to control the pH value of desulfuration liquid

an intelligent online pH value controller can be installed in the said system; in addition

a gravity type dehydration tank can be added in the system

using the dust contained in the tank to filtrate solid matters produced in the said system

ensuring further to prevent the system from scaling and clogging. Practice shows that the developed scheme of antiscaling andclogging to be feasible.
