| 摘 要： | 利用天然凹凸棒石粘土制备成的吸收液,用于柴油机废气的净化过程。柴油机废气在喷射反应器中经凹凸棒石粘土溶液吸收脱除其中的碳烟颗粒物及其它污染物质而净化。实验表明该吸收液具有胶体特性,对碳烟颗粒物有较强的亲合力。在实验条件下,废气中的碳烟脱除率可达71 .3% ,NOX 的脱除率为80 . 4 % ,HC和SO2 等有害气体的脱除率均高于90 % ,气体出口温度从2 0 0～2 5 0℃下降到约5 5℃,气相阻力为3 5kPa。

| Abstract: | The attapulgtite clay was selected as absorbent for purifying diesel exhaust gas.Diesel exhaust gas was allowed to pass through a jet bubble reactor(JBR)arragned in the exhaust system of the diesel engine,in which diesel particulates and other contaminants were absorbed by the attapulgite clay solution.The absorbent slurry has colloid property and a strong affinity for the diesel particulates.It shows that under the experimental conition,the diesel particulates are removed by 71.3%,NO_X by 80.4%,HC and SO_2 all by above 90% from the exhaust gas,the temperature of the exhaust gas decreases from 200～250 ℃ to about 55 ℃,and the gas resistance is 3.5 kPa. |
