Abstract

The invention relates to an aluminum profile production line waste heat comprehensive utilization system, and belongs to the technical field of aluminum profile processing. A second heat exchange pipeis utilized to carry out heat exchange on waste heat in high temperature flue gas discharged from an aluminum smelting furnace, a first heat exchange pipe is utilized to be matched with heat conduction powder to use residual waste heat of the aluminum smelting furnace after smelting of the aluminum smelting furnace, the heat exchange efficiency of the first heat exchange pipe and the second heatexchange pipe is high, the heat exchange effect is good, and heat loss is small; the waste heat is utilized to heat tap water in the first heat exchange pipe and the second heat exchange pipe into hotwater, the hot water is temporarily stored in a heat preservation water tank, when a boiler needs to use water, the hot water stored in the heat preservation water tank can be directly used, the heating time of the boiler is shortened, the waste heat of the aluminum smelting furnace is made full use of, the utilization rate of the waste heat is high, coal, other fuels and consumption of electricenergy are saved, the economic value is high, environmental pollution is reduced, greenhouse effects are reduced, and the aluminum profile production line waste heat comprehensive utilization system accords with policy requirements for energy conservation and environmental protection of our country, and has great promotional value.

Description

technical field [0001] The invention relates to the technical field of aluminum profile processing, in particular to a comprehensive utilization system for waste heat of an aluminum profile production line. Background technique [0002] The aluminum processing and production industry has experienced decades of development. With a large number of introductions and its own efforts to develop, a complete industrial chain from primary aluminum production to aluminum product sales has been formed in China, and every link in production Almost all have experienced technological innovations. However, the development of industry has also brought about its negative effects. Today, when energy is increasingly tense and environmental pollution is no longer just a topic of public discussion, it exists as a strong control standard for enterprises. The aluminum smelting furnace Yield and energy consumption control will be particularly important. The equipment used in aluminum smelting ha...
