Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery devices, specifically a converter gas waste heat recovery device with water-cooled wall heat exchange plates. Background Technology

[0002] Waste heat recovery technology refers to the use of a series of technical means to recover and utilize waste heat generated during industrial production processes, converting it into usable energy such as hot water, steam, or electricity. The application of this technology can significantly improve energy efficiency, reduce energy waste, lower production costs, and also help reduce greenhouse gas emissions, thus achieving energy conservation and emission reduction goals.

[0003] Common converter gas waste heat recovery devices typically use a fume hood module to collect the gas produced by the converter, and then transfer the heat from the gas to cooling water through a heat exchange module to generate steam or hot water. Finally, the gas is recovered and reused through a furnace gas recovery module.

[0004] When recovering waste heat from converter gas, spraying is generally used to cool the converter gas and reduce dust in it. However, during the water mist cooling process, the sensible heat of the gas is absorbed by the water and converted into the latent heat of the water vapor. This latent heat is difficult to utilize effectively, resulting in a complete waste of sensible heat resources below 850℃. Utility Model Content
