This utility model discloses a waste heat recovery device for flue gas from a heat-insulating furnace, comprising a furnace body, a heating chamber located at the upper end of the furnace body, a combustion chamber located at the lower end of the heating chamber, a flue gas outlet located at the upper end of the furnace body, and a connecting pipe located at the upper end of the flue gas outlet. A first heat exchange mechanism for exchanging heat from the flue gas is located inside the connecting pipe. The first heat exchange mechanism includes a fixed plate, a diverter pipe, an inlet pipe, and an outlet pipe. Fixed plates are fixedly installed on both sides inside the connecting pipe, and a plurality of diverter pipes are evenly fixed between the fixed plates. This utility model improves the flue gas filtration and treatment device emitted from the heat-insulating furnace by using diverter pipes to first divert the flue gas, thereby significantly increasing the heat exchange area of ​​the hot flue gas. Compared to devices that only have a heat exchange chamber on the outside of the flue gas outlet pipe, this device can achieve better heat exchange.
