摘要
采用电石渣浆经处理后配制成的电石渣试样作为脱硫剂，对除尘后锅炉烟气进行脱硫实验，在烟气巾s与c质量比约为1：30、吸收体系pH为7～8、温度为15℃的条件下，平均脱硫率达96．35％。采用电石渣浆上层清液作脱硫剂对锅炉烟气进行脱硫的工业试验，在烟气流速为2．8～4．2m／s、脱硫塔内nCa：n5=1．2：1、体系pH为7～8的条件下，平均脱硫率达90．66％，且脱硫塔出气口处SO2质量浓度明显低于GB13271-2001《锅炉大气污染物排放标准》。
An experiment on flue gas desulfurization was carried out using samples prepared from treated carbide slag slurry as desulfurizing agent. Under the conditions of mass ratio of S to C about 1 ： 30, absorption system pH 7 - 8 and temperature 15℃, the average desulfurization efficiency is 96.35 %. In the industrial test, the supernatant of carbide slag slurry was used as desulfurizing agent. When the flue gas velocity is 2.8 -4.2 m/s, r/Ca： r/s in the desulfurizer is 1.2 ： 1 and the system pH is 7 -8, the average desulfurization efficiency is 90.66%, and the mass concentration of SO2 from the outlet of the desulfurizer is much more lower than the state emission standard for atmospheric pollutants from boiler （GB 13271--2001 ）.
