摘　　要：以动力电池单体自动化拆解线的混合废气为研究对象,通过实验考查了碱液吸收、活性炭吸附及碱液吸收＋活性炭组合工艺对拆解线混合废气的处理效果,结果显示,混合废气先经碱液吸收,再经活性炭吸附之后,出口浓度比国家排放标准限值低;当质量分数为10%的碱溶液吸收时间为2~3 s、煤质柱状活性炭接触时间为1~2 s时,恶臭物质去除率达95.0%,氟化物去除率达91.8%;整个废气处理系统具有很好的实际应用前景,经测算,装机功率小于1 k W/1 000 m3,运行成本小于1元/1 000 m3。In this paper, the exhaust gas of vehicle power cell by automated disassembly line is used to conduct study, through experiments it is investigated the treatment effects of alkali absorption, activated carbon absorption and the combina- tion of these two processes on the mixed exhaust gas of disassembly line. The result shows that the concentration of exhaust gas is lower than the limit value of the emission standard after first absorption by alkali and following absorption by activated carbon. Under the experimental conditions of 10% sodium hydroxide lye absorption for 2 - 3 s and activated carbon contact for 1 -2 s, the removal efficiency of odor and fluoride can reach 95.0% and 91.8% respectively. It is proved that the whole system is prospective in practice and it is measured that the installed power of purification system is less than 1 kW/1 000 m3 and running cost less than 1 yuan/1 000 m3.
