The utility model relates to the technical field of flue gas denitration, in particular to a calcium carbide flue gas denitration system, which comprises a plurality of spray guns positioned on a drying kiln, a compressed air source, a dilution water supply device, a urea storage device and a solution mixing device, the compressed air source is communicated with the solution mixing device, and the solution mixing device is communicated with the spray gun through a urea mixed liquid conveying pipeline. Urea and dilution water are evenly mixed through the solution mixing device and then sprayed into the drying kiln, a reducing agent is evenly distributed in the boiler, denitration reaction can be fully carried out, ammonia gas is prevented from overflowing, compressed air of an original pneumatic conveying system and condensate water of the carbide slag cooler are utilized, and the utilization rate of raw materials is improved. The utilization rate of resources is improved, and the convenience of the system is
