Converter primary flue gas ultra-low emission carbon reduction process system

The invention relates to the technical field of flue gas purification of steel plants, in particular to a converter primary flue gas ultra-low emission carbon reduction process system which is characterized in that an efficient steam spraying tower is connected with a converter through an evaporation cooling flue; the dehydrator is connected with the efficient steam spraying tower through the circular seam washer, and an outlet of the dehydrator is connected with the wet-type electric dust remover through a pipeline; an inlet of the primary dust removal fan is connected with an outlet of the wet-type electric dust remover, an outlet of the primary dust removal fan is sequentially connected with a recovery cup valve and a diffusion cup valve, the recovery cup valve is connected with the gas cooler through a pipeline, and the diffusion cup valve is connected with the carbon reduction tower. Through the integral structure of the equipment, carbon dioxide in the primary flue gas of the converter can be captured i
