摘　　要：介绍了一种应用于分离液相中的气体的轴向入口管式脱气器。运用Fluent软件对其气液分离效果进行了三维数值模拟,结果表明,轴向入口管式脱气器具有良好的气液分离效果,其分离效率随着入口速度和气泡粒径的增大而增大,当气泡粒径大于40μm时,只需较低的入口速度即可达到较高的脱气效率。A tubular degasser with axial inlet and applied to separate gas from liquid was introduced. Having Fluent software adopted to simulate its gas-liquid separation effect three-dimensionally shows that,the tubular degasser with axial inlet has good separation effect; and the separation efficiency can increase with the increase of both inlet velocity and diameter of bubbles; and as for a bubble diameter larger than 40μm,a lower inlet velocity can bring about a high separation efficiency.
