摘要

从技术原理上对石灰中水处理技术、再碳化技术以及石灰石湿法烟气脱硫技术三者结合的火电厂资源循环利用模式的可行性进行了分析。将石灰中水处理及再碳化处理所得沉渣作为石灰石湿法脱硫的原料

而脱硫后净烟气中的CO2可用作石灰中水处理出水的再碳化剂。对该模式下可能存在的问题进行了探讨

认为将以上3种成熟技术有机地组合起来

可有效实现火电厂资源及其废弃物的循环利用。

Abstract

The feasibility of recycling utilization mode for resouces in thermal power plants

which combined three technologies

namely technology of intermediate water treatment using lime

technology of recarbonization

and technology of limestone wet flue gas desulphurization(FGD) together

has been analysed from technical principles.The deposited slags obtained from intermediate water treatment using lime

and from recarbonization treatment are used as raw materials in wet FGD using limestone

while the CO2 in purified flue gas after FGD can be used as recarbonization agent in effluent water from intermediate water treatment using lime.An approach to the problems may appear in said recycling utilization mode has been made

it is believed that the organic combination of three matured technologies above-mentioned can effectively realize the recycling utilization of resources and their wastes in thermal power plants.
