Abstract

The invention discloses a waste heat power generation system based on blast furnace superconducting cooling. The waste heat generating system mainly comprises a blast furnace body (1), a power generation system (12), a steam utilization device, one or more superconducting ring-shaped heat exchange rings (2) arranged along the side wall of the blast furnace body (1) in a layered encircling manner, poured solidified bodies (10), and lower guide pipes (32), wherein the poured solidified body is arranged on each superconducting ring-shaped heat exchange ring and made from a wear-resistant heatproof anti-seismic carburizing-proof elastic castable refractory; each lower guide pipe is used for being connected with the lower circulation opening of the corresponding superconducting ring-shaped heat exchange ring in series. According to the waste heat power generation system, hot water subjected to heat exchange is centrally discharged through the superconducting ring-shaped heat exchange rings embedded on the side wall of the blast furnace body and a ring-shaped pipeline system corresponding to the superconducting ring-shaped heat exchange rings, so that the heat exchange intensity is enhanced, the heat exchange efficiency and the cooling efficiency are improved, the temperature of traditional cooling water is increased to 250 DEG C from 40 DEG C, and can be increased to 400 DEG C after the traditional cooling water passing the superconducting ring-shaped heat exchange rings twice, so that the cooling waste heat can be utilized to realize power generation.

Description

technical field [0001] The invention relates to a high-efficiency power generation system for blast furnace cooling heat, in particular to a waste heat power generation system based on blast furnace superconducting cooling. Background technique [0002] During the blast furnace production process, the cooling of the furnace wall requires a large amount of water to take away the heat to reduce the temperature of the furnace wall, so as to meet the process temperature requirements of the normal production of the blast furnace. The waste heat taken away by the cooling of the blast furnace and the surface heat dissipation ratio of the blast furnace wall account for 5% and 0.5% of the total heat consumption of the blast furnace respectively. Based on the simple calculation that 400-800Kg of coke is required to produce one ton of pig iron, there are about 20-40Kg of coke produced Thermal energy is dissipated in the form of cooling water heat. Based on the 600 million tons of iron...
