Comprehensive dust removal method and device for reducing resistance of air-flue gas system

The invention discloses a comprehensive dust removal method and device for reducing resistance of an air-flue gas system. Pretreated flue gas is fed into an electric dust remover, and charged particles are generated through corona discharge, so that dust is adsorbed on an electrode plate in the electric dust remover; a power supply of the electric dust remover adopts a self-adaptive control method, according to capacitance change between electrode plates, output voltage is always maintained at a critical position below a spark starting point under an instantaneous working condition, and stable electron flow is formed; dust adsorbed on the electrode plate is collected in time; and desulfurization treatment is conducted on the flue gas subjected to dust removal by the electric dust remover, and finally the flue gas is discharged. According to the comprehensive dust removal method and device for reducing the resistance of the air-flue gas system, the discharge effect of the dust removal power supply is improved
