Abstract
A vehicle-mounted hydrogen supply method and device for hydrogen-rich smelting in a blast furnace or shaft furnace, combining steel plant hydrogen supply requirements with vehicle-mounted hydrogen supply technologies to construct a vehicle-mounted hydrogen supply system applied to hydrogen-rich smelting in a blast furnace or shaft furnace, thus providing an effective and reliable pathway for safe and stable hydrogen supply in a blast furnace or shaft furnace smelting process to perform hydrogen-rich smelting testing and production. Compared with a newly-built hydrogen plant, the invested construction cost is low, the operation flow is simple, the method and device are not limited by technical upgrading and transformation, and the flexibility is high. At the same time, two working long pipe vehicles and two pressure reducing system intake pipelines are used for solving the problem of continuous hydrogen supply required for hydrogen-rich smelting in a blast furnace.
