Research on Flow Field Characteristic and Capture Efficiency of High Temperature Dust Capture Process of Top Exhaust Hood

This paper simplifies dust control problems of high temperature contaminant source in actual engineering, and takes such problems as subjects to build relevant model. Then, the gas-solid two-phase flow simulation is used to research and resolve pollution source control problem. Through comparison and analysis of all the numerical simulation results, change laws including the change of flow field of operatition space, axial velocity of dusty gas flows, dust capture efficiency and so on were summarized. Thus the optimal control effect in each case can be achieved.
