摘要

结合某电厂600MW机组湿法烟气脱硫装置(吸收塔为3层喷淋塔)

借助FLUENT软件

对多种烟气负荷下不同浆液循环泵组合方式也即不同喷淋层组和方式下的塔内烟气流场进行模拟研究。结果表明

75%及50%烟气负荷下3层喷淋层全部投运时吸收塔内烟气流场最均匀;70%烟气负荷下停运1层喷淋层时

第1层和第3层喷淋层组合时塔内烟气流场相对较均匀;50%烟气负荷下停运1层喷淋层时

第1层和第2层喷淋层组合时塔内烟气流场相对较均匀。

Abstract

Combined with the wet flue gas desulphurization (WFGD) system of 600 MW unit in one power plant

and with the aid of FLUENT software

simulation study on the different combination modes of slurry-circulating pumps under several flue ga loads

i.e.flue gas field in the said tower under different combination modes of different spraying levels

have been carried out.Results shwo that the flue gas flow field in the absorption tower is most uniform in the case of the three spraying levels being in operation under 75% and 50% flue gas load;the flue gas flow field is relatively more uniform in the event of one spraying level being stopped

and the first spraying level combined with the third spraying level being in operation under 70% flue gas load;the flue gas flow field in the said tower is also relatively more uniform in the event of one spraying level being stopped

and the first spraying level combined with the second spraying level being in operation under 50% flue gas load.
