The invention discloses a heat recovery system of an aluminum homogeneous furnace. The heat recovery system comprises a furnace body, a nozzle group and a cooling-preheating chamber, wherein a hearth used for heating an aluminum material is formed on the furnace body; the nozzle group is arranged on the end wall of one side of the hearth; and the cooling-preheating chamber comprises an air inlet passage, a material storage space and an exhaust passage which are communicated sequentially. When the cooling-preheating chamber is used as a cooling chamber, the heated aluminum material from the hearth is placed in the material storage space; and cold air from the air inlet passage cools the aluminum material in the material storage space, and then is exhausted out of the cooling chamber through the exhaust passage. The system further comprises a first heat reservoir which is arranged in the exhaust passage of the cooling-preheating chamber; when the cooling-preheating chamber is used as the cooling chamber, the first heat reservoir is used for absorbing waste heat of air flowing through the exhaust passage; and when the cooling-preheating chamber is used as a preheating chamber, the cold aluminum material is placed in the material storage space, and cold air is heated through the first heat reservoir and then fed into the air inlet passage for preheating the aluminum material in the material storage space.
Description
technical field [0001] The invention relates to a waste heat recovery system, in particular to a waste heat recovery system for a homogeneous furnace. Background technique [0002] In the face of increasingly severe environmental problems and energy crises, the whole world is vigorously advocating energy conservation and emission reduction, especially for industrial kiln related industries with serious energy consumption and pollution. Factors that personnel must consider when designing such equipment. [0003] Taking the aluminum material homogenization furnace as an example, the air temperature at the outlet of the cooling chamber usually reaches about 400 degrees Celsius. If these high-temperature air are directly discharged into the environment, it will not only cause energy waste but also cause a certain degree of damage to the environment. [0004] As disclosed in Chinese Patent No. 201020562151.3, a homogenizing furnace and aging furnace preheating system includes a...
