Abstract：A 3D entity model for an electrostatic precipitator shell is built by ANSYS software,and it is analyzed by the finite element method. The stress and the transformation of the shell are received. The result indicates that the shell primary structure design is rational,but dimensional design is conservative,and there is some optimization space for constructional elements. A primary structure is designed by the finite element method,and a new shell structure is analyzed by the finite element method. The new shell structure is rational. The strength and stiffness demands are satisfied. The research result has a practical guiding significance in electrostatic precipitator shell design.
