【摘要】 文章对二氧化硫污染现状及CFB-FGD系统的应用情况进行了综述,介绍其反应机理。并根据某厂的要求,选择了以喷淋塔为主体的石灰湿法脱硫工艺,根据相关原理进行了脱硫系统工艺计算,确定了脱硫塔、烟气和浆液管道、循环池等的主要尺寸,进而选择了风机和循环泵,由所得浆液流量及选取的浆液停留时间计算得出循环池的尺寸,并分析其工艺的经济可行性。为锅炉烟气脱硫提供了参考依据。更多还原

【Abstract】 The design had carried on the summary to the sulfur dioxide pollution and the CFB-FGD system application situation,and introduced its reflect mechanism.And according to the request of the project description,it had chosen the wet lime flue gas desulphurization process which took the sprays tower as the main body.According to the correlation principle,it had carried on computation about the desulphurization system and had determined the main dimension of the desulphurization tower,the haze and the size pipeline and so on.Then it had calculated the circuitry resistance and has chosen the air blower and the circulating pump.It obtained the size of the circulation pond by the size current capacity and the selection size resident time to demister the spray nozzle,and economic viability were also introduced in the paper.It can supply reference basis data for this kind of enterprise to treat sulfur dioxide in flue gas.更多还原
