Embodiment

[0029] 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 current source-based bipolar oscillating type waste heat power generating system. The current source-based bipolar oscillating type waste heat generating system mainly comprises a blast furnace body (1), a power generation system (12), a steam utilization device, more than one superconductive annular heat exchange ring (2) arranged along the side wall of the blast furnace body (1) in a layered surrounding type, a waste heat control processing system and the like. According to the current source-based bipolar oscillating type waste heat power generating system, hot water subjected to heat exchange is concentrately guided out through the superconductive annular heat exchange rings embedded in the side wall of the blast furnace body and an annular pipeline system corresponding to the superconductive annular heat exchange rings, so that the heat exchange strength is increased, the heat exchange efficiency and the cooling efficiency are improved, and in addition, the temperature of cooling water in a traditional mode is increased to 250 DEG C from 40 DEG C, and is overheated to 400 DEG C after being treated by the superconductive heat exchange rings twice, and thus cooling waste heat can be used for power generation.

Description

technical field [0001] The invention relates to a high-efficiency power generation system for cooling heat of a blast furnace, in particular to a waste heat power generation system based on a bipolar oscillation of 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 ton...
