摘要：

The flow field distribution in burnt lime hydrator has been investigated by a software FLUENT, with k-epsilon turbulence model and MRF method. The simulation result shows that when four blades deflect 30 degrees, the whole velocity gradient of flow reduces and the recirculation zones also diminish; when the rotational speed is 75r/min, the turbulence kinetic energy of stir zone between two axes becomes larger, which can raise stirring effect and reduce fugitive dust, so it is easy to achieve the purpose of improving the environment of work condition.
