The invention belongs to the technical field of metallurgical blast furnace slag and smoke waste heat utilization, and particularly relates to a thermoelectric power generation system and technology based on metallurgical blast furnace slag and smoke waste heat. The power generation system comprises a blast furnace slag flushing subsystem, a purification-free heat exchange subsystem and a thermoelectric power generation subsystem. The blast furnace slag flushing subsystem comprises a blast furnace slag granulator, a boiling kettle, an extraction turbine and a conveying belt. The purification-free heat exchange subsystem comprises a water pump, a smoke heat exchanger and a cooling tower. The thermoelectric power generation subsystem comprises a semiconductor thermoelectric power generation board, a high temperature end heat exchanger and a low temperature end heat exchanger. According to the power generation system, the blast furnace slag and the smoke waste heat are comprehensively recycled, so that heat pollution caused to the outside is reduced; meanwhile, the amount of blast furnace slag flushing circulating water is reduced, and a water purification device is omitted; and the advanced semiconductor thermoelectric power generation technology is adopted, running is quiet, the structure is simple, firmness and durability are achieved, and high power generation efficiency is achieved.
Description
technical field [0001] The invention belongs to the technical field of utilization of metallurgical blast furnace slag and flue gas waste heat, and specifically relates to a system and process for generating electricity based on temperature difference of metallurgical blast furnace slag and flue gas waste heat. Background technique [0002] my country is a big steel producer in the world. In 2013, it ranked first in the world with 779 million tons of crude steel output. Iron and steel companies use water-based treatment of blast furnace slag in the process of blast furnace smelting, which makes it highly active. It can not only As an additive to concrete in the construction industry, and can be used to make cement, if the wind quenching method is used, the activity of slag will be changed, making it difficult to reuse slag resources. [0003] During metallurgical blast furnace smelting, a large amount of high-temperature flue gas will be discharged, and a large amount of blas...
