Blower has complex structure, and can't directly do research on flow experiment. Now mathematical simulation is the chief manner of research in blower's flow field. The research adopts the theory of impeller machine three-dimensional flow, and sets up the mathematical model. It does numerical calculation to complex flow field and border. Then the flow field's data are used to get graphic processing by MATLAB. Graphic data processing can qualitatively and quantificationally analyze the physical quantum's change of blow field. This paper is aimed at limited difference numerical calculation and graphic data processing, and brings forward improvement on the structure by analysis of blow field data.
