The invention relates to the technical field of waste lead accumulator recovery, and in particular, discloses an environmental-protection lead melting system. The environmental-protection lead meltingsystem comprises a lead melting furnace device, a waste gas recovery device and a lead liquid recovery device, wherein the lead melting furnace device comprises a combustion furnace, a heating furnace, a feed port, an exhaust port, a lead liquid outlet, an intake port, a gas pipe and a chimney; the waste gas recovery device comprises a first recovery tank whose intake port communicating with theexhaust port, and a second recovery tank whose intake port communicating with a gas outlet; the first recovery tank and the second recovery tank are used for holding recovered reaction liquid; and thelead liquid recovery device comprises a first cooling chamber whose liquid inlet pipe communicating with the lead liquid outlet, a second cooling chamber, a water tank, a first conveying belt and a second conveying belt. The environmental-protection lead melting system prevents environmental pollution by waste gas, and is high in lead recovery rate.
