Hydrogen energy ironmaking type comprehensive recovery device

Abstract

The invention relates to the field of hydrogen energy ironmaking type comprehensive recovery devices, in particular to a hydrogen energy ironmaking type comprehensive recovery device. The device comprises a main body, a supporting mechanism, a transferring mechanism, a steam turbine mechanism, a switching mechanism and a quantifying mechanism. The main body can be supported through the supporting mechanism, a space can be provided for the transferring mechanism to transfer rough molten iron, molten iron can be transferred through the transferring mechanism, and therefore the molten iron can be conveniently injected into the next refining procedure; molten iron melted inside the main body can be quantitatively injected into the transferring mechanism through the quantifying mechanism, the situation that too much molten iron is injected to cause overflow and waste of the molten iron is avoided, through arrangement of the steam turbine mechanism, steam turbine blades can be pushed to rotate through products obtained after hydrogen combustion reaction, and therefore the effect of converting steam energy into mechanical energy is achieved; and additional values during ironmaking are increased, the mechanical energy of the steam turbine mechanism can be converted into electric energy, and the economic benefits of a factory area are increased.

Description

technical field [0001] The invention relates to the field of a hydrogen energy ironmaking type comprehensive recovery device, in particular to a hydrogen energy ironmaking type comprehensive recovery device. Background technique [0002] The process of extracting metallic iron from iron-containing minerals (mainly iron oxides) mainly includes blast furnace method, direct reduction method, smelting reduction method, and plasma method. From the perspective of metallurgy, ironmaking is the reverse behavior of iron rusting and gradual mineralization. Simply put, pure iron is reduced from iron-containing compounds. In actual production, pure iron does not exist, and what is obtained is iron-carbon alloy. [0003] Nowadays, in response to the call for energy saving and emission reduction advocated by the society, the traditional ironmaking industry is also looking for new and efficient ironmaking processes that reduce pollution, thus giving birth to the method of using hydrogen e...

[0003] Nowadays, in response to the call for energy conservation and emission reduction advocated by the society, the traditional ironmaking industry is also seeking new and efficient ironmaking processes that reduce pollution, and thus the method of using hydrogen energy for ironmaking was born, using hydrogen as a heat source and at the same time as a The reducing agent replaces the iron element in the iron oxide. When a large amount of hydrogen is used, a large amount of reaction product water vapor will be generated inside the blast furnace. Most of the general ironmaking equipment directly discharges the non-polluting water vapor, which is not available. of water vapor is recycled, reducing the economics of the ironworks
