The utility model discloses an industrial flue gas desulfurization and denitrification accurate control system which comprises an industrial raw flue gas and desulfurizer preparation system, and the industrial raw flue gas is connected to an inlet of a waste heat boiler system through a main flue system and a waste heat boiler system inlet regulating valve. When the system is initially operated, the waste heat boiler system is provided with a 100% bypass, the reasonable temperature required by the system can be effectively adjusted in real time, and flue gas behind the waste heat boiler enters the desulfurization device, the dust removal device, the denitration device, the desulfurization and denitration main fan and the chimney; viscous substances, dust and sulfur dioxide possibly damaging a catalyst in the flue gas are removed in the dust removal device, so that stable operation of the catalyst of a subsequent denitration system is effectively protected, and the catalyst is prevented from being blocked and
