Dry quenching circulating gas explosion-proof equipment

The invention discloses dry quenching circulating gas explosion-proof equipment, and relates to the technical field of dry quenching engineering. The explosion-proof equipment comprises a dry quenching furnace, a boiler, a dust remover, a circulating fan, a circulating gas communicating pipe, a circulating gas monitoring system and a circulating gas mixing mechanism, wherein the dry quenching furnace, the boiler, the dust remover and the circulating fan are communicated through a circulating gas communicating pipe. The equipment is reasonable in structure, realizes real-time monitoring on the concentration of combustible gas in circulating gas in a positive pressure area and a negative pressure area, and enables the circulating gas in the positive pressure area or the negative pressure area to be mixed with air or nitrogen or fully mixed with the air and the nitrogen according to different monitoring results, so that the phenomenon of gas layering is avoided, and sufficient combustion is facilitated.
