Flue gas desulfurization and denitration treatment system for coal-fired power plant

The invention relates to the technical field of devices of desulfurization and denitration, and discloses a flue gas desulfurization and denitration treatment system for a coal-fired power plant. The system comprises a base, a cooling box, a liquid storage tank, a spraying device and a smoke outlet, wherein the bottom of the cooling box is fixedly connected to the left side of the top of the base, the bottom of the liquid storage tank is fixedly connected to the top of the base, and the bottom of the spraying device is fixedly connected to the top of the liquid storage tank; and the smoke outlet is formed in the right side of the top of the spraying device. According to the flue gas desulfurization and denitration treatment system in the coal-fired power plant, flue gas which is introduced into the system is oxidized and decomposed through an oxidizing liquid, then ammonia gas is introduced into a reactor, and then the treated flue gas is introduced into the reactor through a gas transfer pipe; and electron b
