Title:
CYCLONE- AND MOLTEN IRON WALL-BASED SMELTING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/138057
Kind Code:
A1
Abstract:
The present invention relates to the technical field of metal smelting. Disclosed are a cyclone- and molten iron wall-based smelting apparatus and method. The smelting apparatus comprises an outer cylinder and an inner cylinder; a gasification reduction reaction area and a gas reforming area are sequentially provided in the outer cylinder; the inner cylinder is located in the reduction reaction area; a plurality of heat exchange tubes are arranged in sequence in a circumferential direction to form the inner cylinder; the inner cavity of the inner cylinder is communicated with a main gas outlet; the end of the inner side of the heat exchange tubes distant from the main gas outlet is provided with a cold medium outlet. Or, the smelting apparatus comprises a main reaction furnace, a preheating pre-reduction furnace, and a high-temperature gas-solid separation apparatus which are sequentially communicated; the end in the main reaction furnace facing the preheating pre-reduction furnace is sequentially provided with a heating area, a combustion area, a gasification area and a reduction area; a solid-phase output end of the high-temperature gas-solid separation apparatus is communicated with a second powder nozzle of the gasification area. According to the present invention, a plurality of reactions are integrated into one reaction furnace, and thus, the metal smelting process is simplified.
