摘要
Abstract
In order to study the wall erosion mechanism of cyclone separator,the internal gas flow field of cyclone and the movement rule of particle had been analyzed with the RSM model and DPM model,and also studied the force of particles on the failure surface with the UDF.It was found that 25 mm come within the scope of top barrel was the most severe erosion position.The partial perforated of barrel and the erosion at the bottom of cyclone was also the failure position.There were obvious solid particles aggregation phenomenon in this area.From the force analysis of single particle,finding that the force equilibrium of middle size particles and the big size particles at the top of the cylinder and the bottom of the cone were the main reason for the gray zone appearance,which is adding to the erosion of the top and the ash hopper.关键词
