AI Technical Summary
Existing gas-based vertical shaft furnace cooling systems suffer from problems such as gas crosstalk, heat waste, carbon precipitation risk, and unreliable cooling structures under high pressure, which affect reduction efficiency and equipment safety.
It adopts a cooling gas circulation loop, a heat recovery unit, a cooling gas purification and circulation unit, and an annular cooling structure. The gas flow is controlled by a circulating fan, and a heat exchanger and a high-temperature cyclone dust collector are installed. An annular paving brick plate and a support plate are used to form a cooling gas collection annular cavity to control the composition ratio of the cooling gas and prevent carbon precipitation.
It improves reduction efficiency, saves energy and reduces consumption, prevents gas short circuits, avoids carbon precipitation, extends equipment life, and ensures system safety and uniform cooling.
