Cyclone SCR (Selective Catalytic Reduction) denitration device suitable for cement kiln tail high-dust flue gas

The invention relates to the technical field of environmental protection, in particular to a cyclone SCR denitration device suitable for cement kiln tail high-dust flue gas. The cyclone SCR denitration device suitable for the high-dust flue gas at the tail of the cement kiln comprises a flue gas supply system which is provided with a flue gas inlet pipeline and a flue gas outlet pipeline; a gas inlet in the upper side of the cyclone denitration tower is communicated with the flue gas inlet pipeline, and a gas outlet in the lower side of the cyclone denitration tower is communicated with the flue gas outlet pipeline; the vortex plate type catalyst module is arranged in the cyclone denitration tower and located between the air inlet and the air outlet of the cyclone denitration tower, a vortex catalyst channel is formed in the vortex plate type catalyst module, and the vortex flow direction of the vortex catalyst channel is consistent with the airflow rotation direction in the cyclone denitration tower; and the
