| 摘 要： | 下行循环流化床反应器要求气固分离器具有分离效率高、气相停留时间短、压力损失小、设备磨损小等特点。利用气固二相在惯性上的差别,提出了一种新型同轴双锥两级气固快速分离器,并以FCC(F lu id Catalytic Crack ing)为循环物料对该型分离器的分离特性进行了研究。结果表明,同轴双锥两级气固分离器的分离效率在98%以上,气固分离器的压力损失在100 Pa以下,设备磨损小,能够满足下行循环流化床反应器的要求。

| Abstract: | New kind of gas-solid fast separator with high separating efficiency,short gas resident time,low pressure loss and long life is urgently needed to couple with concurrent downer reactor.To meet this demand,a new type of gas-solid fast separator with two coaxial cones was proposed.The separating characteristics of the new proposed(separator) were investigated in a cold model of concurrent downer reactor by using fluid catalytic cracking(FCC) as circulating particles.The results indicate that the separating efficiency is more than 98%,the pressure drop of the separator is less than 100 Pa,and the abrasion is very little. |
