The present invention relates to the technical field of waste heat recovery facilities for steelmaking converters in steelmaking enterprises, and specifically to a converter primary flue gas quenching and fire extinguishing waste heat recovery method and device. Flue gas at the outlet of the vaporization cooling flue, with a temperature of 900-1000°C, enters a radiant waste heat boiler for radiative heat exchange, and the heat recovered is recycled. Flue gas at the outlet of the radiant waste heat boiler, with a temperature of 660-700°C, enters a water-cooling chamber, which extinguishes open flames and fire starters carried by dust. The flue gas, with these fire starters eliminated, then enters a convection waste heat boiler through a gas pipeline for convection heat exchange. This heat exchange reduces the flue gas temperature from 550-600°C to approximately 200°C, and the heat recovered is recycled. The present invention eliminates open flames and fire starters in the flue gas through the water-cooling chamber, avoiding the risk of explosion below the ignition point and effectively improving system safety. Simultaneously, the radiant and convection waste heat boilers fully recover the low-temperature waste heat in the converter flue gas, effectively reducing the production cost of steel products.
