Abstract

The invention discloses a thermoelectric generation device using steel ladle surface waste heat. The device comprises a protective cover, a skeleton, an upper heat insulating plate, a thermoelectric system, a lower heat insulating plate and a cooling system. The skeleton is a semi-cylindrical support; the protective cover is welded on the skeleton; the upper heat insulating plate, the thermoelectric system and the lower heat insulating plate are fixed on the skeleton by bolts to form a semi-cylindrical shape; the cooling system is arranged outside the thermoelectric system; and the device is composed of two semicircular cylinders. The technical scheme of the invention has the characteristics of simple structure, small size, no mechanical movement and no noise, so that the waste heat recovery and utilization in the limited space can be realized.

Description

technical field [0001] The invention relates to the field of iron and steel metallurgy, in particular to a thermoelectric power generation device utilizing the waste heat on the surface of a ladle. Background technique [0002] In the steelmaking process of iron and steel production, the refining, transportation, standing, pouring and other links of high-temperature molten steel (about 1600 ° C) are all carried out in the ladle container. Although the development of heat preservation technology has reduced heat loss to a certain extent, due to the Due to the huge temperature difference between the liquid and the external environment, there is still considerable heat on the surface of the ladle that is inevitably lost to the environment. According to the field test, when the molten steel is contained, the surface temperature of the ladle is in the temperature range of 100-400°C. Due to the limitations of space and technology, it is still impossible to utilize this part of wa...
