Strip steel annealing cooling exhaust waste heat boiler

The utility model relates to a strip steel annealing cooling exhaust waste heat boiler which comprises a collecting box and a boiler body, a containing table is arranged in the collecting box, a conveying pipe is communicated between the collecting box and the boiler body, a wide-mouth collecting cover is arranged at the end, close to the collecting box, of the conveying pipe, and the end, close to the boiler body, of the conveying pipe is fixedly connected and communicated with a filtering cleaning box. The strip steel annealing device has the beneficial effects that heat in the strip steel annealing process can be effectively collected and recycled through the boiler and the collecting device, and the situation of resource waste is effectively avoided; and meanwhile, water vapor generated after the boiler is heated is utilized again, the waste heat utilization rate is further increased, the situation of energy waste is avoided, meanwhile, impurities and the like in hot gas can be effectively adsorbed and fi
