Dust removing method based on electric dust remover positive plate rapping apparatus

The invention discloses a dust removing method based on an electric dust remover positive plate rapping apparatus. A computer system is mounted on the electric dust remover positive plate rapping apparatus; a top excitation hydraulic cylinder and a top impacting hydraulic cylinder are mounted above a positive plate set; a bottom excitation hydraulic cylinder and a bottom impacting hydraulic cylinder are mounted at the lower end of the positive plate set; a thickness tester and a displacement sensor are mounted on the surface of any positive plate. The dust removing method based on the electric dust remover positive plate rapping apparatus comprises the following steps: firstly, obtaining the thickness of a dust layer through the thickness tester, judging whether the dust removal is needed, carrying out sweeping-frequency rapping by using the top/bottom excitation hydraulic cylinder firstly when the dust removal is needed, impacting and rapping through the top/bottom impacting hydraulic cylinder when the displ
