The transmission mechanism of mobile electrode electrostatic precipitator(MEEP)brush was improved.The gear and sprocket transmission part was transformed into gear box structure

to increase the stability of key component.Thus

the installation process was simplified

the dust removal performance was enhanced

and the overall performance of the MEEP was improved

from several aspects.Furthermore

the finite elements software ANSYS was employed to optimize the gear housing.The box wall thickness was taken as the variable and the dynamic property of the gear box was taken as the aim.The successive approximation approach was applied.The results indicate the optimum box wall thickness should be 6mm.
