Waste heat power generation device for smelting industry

The utility model discloses a waste heat power generation device for the smelting industry. The device comprises a shell, the top of the shell is connected with a box body through bolts, the bottom ofthe shell is connected with a plurality of lower sealing heads through bolts, the top end of the box body is connected with a steam pipe through a flange, a plurality of heat exchange pipe rows are welded to the bottom of the box body, the bottom ends of the heat exchange pipe rows are connected with a water inlet pipe through flanges, and the heat exchange pipe rows are located in the shell. According to the utility model, the water is heated into steam while the flue gas is cooled through heat exchange of the heat exchange tube bank; steam generated by smelting waste heat can be used for driving the steam generator set to generate electricity; compared with traditional jacket heat exchange, the waste heat recovery efficiency of the device is remarkably improved, meanwhile, the multiplelower end sockets are inst
