Embodiment

[0026] Such as Figure 1~3 As shown, the blast furnace body 1 of the present invention is the same as the traditional blast furnace, and is divided into four parts, the furnace shaft, the bosh, the furnace waist and the furnace seat. The present invention is provided with more than one superconducting annular heat exchange ring 2 in a layered and surrounding manner along the side wall of the blast furnace body 1, that is, these superconducting annular heat exchange rings 2 are arranged along the shaft and bosh of the blast furnace body 1. , the furnace waist and the furnace seat are arranged, and the side wall surface of the entire blast furnace body 1 is completely covered. Every circle around the side wall of the blast furnace body 1 is a layer, and the midline points of all superconducting annular heat exchange rings 2 on the same layer are in the same plane, so along the side wall surface of the blast furnace body 1 A superconducting annular heat exchange ring 2 with seve...

Abstract

The invention discloses a blast furnace superconductive cooling waste-heat power generation system based on a current source. The system is mainly formed by a blast furnace body (1), a power generation system (12), a steam utilization device, more than one superconductive annular heat transfer ring (2) in layered encircling arrangement along the side wall of the blast furnace body (1), pouring solidification bodies (10) made of wear-resisting heat-shock-resistant anti-permeability coal elastic refractory castables and arranged on each superconductive annular heat transfer ring (2), and lower conduits (32) connected in series with a lower circulation port of each superconductive annular heat transfer ring (2). According to the system, hot water obtained after heat transfer is exported in a concentrated manner through the superconductive annular heat transfer rings embedded in the side wall of the blast furnace body and annular pipeline systems corresponding to the superconductive annular heat transfer rings, so that heat transfer intensity is enhanced, heat transfer efficiency and cooling efficiency are improved, and cooling water temperature is improved from the original 40 DEG C to 250 DEG C; and then, the water is overheated to a temperature of 400 DEG C through twice applications of the superconductive annular heat transfer rings, and thus the cooling waste heat is allowed to be utilized for power generation.

Description

technical field [0001] The invention relates to a blast furnace cooling heat efficient power generation system, in particular to a blast furnace superconducting cooling waste heat power generation system based on a current source. 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 ...
