The invention relates to the technical field of flue gas treatment, in particular to a converter primary dust removal flue gas ultra-clean emission device. The converter primary dust removal flue gasultra-clean emission device is provided with a flue gas cooling and filtering mechanism, so that high-temperature waste gas generated by working of a converter can be conveniently cooled, and the fluegas can be preliminarily and roughly filtered, so that a filtering adsorption plate is prevented from being scalded and damaged by the high-temperature flue gas, and the use stability is improved. The device comprises a converter supporting seat, converter supports, backing ring bearings, a converter backing ring, the converter, a gas suction hopper, a flue gas conveying pipe, a cooling and filtering box, a stirring motor, a speed reducer, a stirring shaft, a blade fixing ring, blades, a filtering plate, a waste gas flow pipe and a desulfurization mechanism, wherein a groove is formed in themiddle of the upper end of
