Abstract

The invention discloses a mineral roasting reduction device. The device comprises a feeding zone, a drying preheating zone, a roasting oxidation reaction zone, a pressure-regulating zone, a reduction reaction zone, a discharging zone and a water-sealing cooling zone, which are arranged from the top down and communicated with one another, wherein the feeding zone is provided with an automatic sealing device; the drying preheating zone is provided with a directional pressurizing device for vacuum-pumping; the roasting oxidation reaction zone is provided with an incendiary agent adding device; the pressure-regulating zone is provided with a plurality of pressure-regulating air doors; the reduction reaction zone is provided with a reducing agent adding device. The mineral roasting reduction device is provided with the directional pressurizing device, so that negative pressure can be generated in the inner part of the device; molecular flows of both an incendiary agent and an reducing agent are in uplink, while mineral is in downlink, so that a convection current movement is formed to ensure conversion affinity of the solid phase and the gas phase; in the device, the mineral sequentially is subjected to drying, preheating, heating, resolving, reducing, water quenching, cooling and discharging from the top down, and all processes are performed in an air-free state thoroughly to complete roasting reaction.

Description

technical field [0001] The invention relates to a mineral roasting reduction device and a method for using the device, belonging to the field of mineral processing. Background technique [0002] Mineral separation and roasting experts and scholars from colleges and universities focus on the research on the principle of mineral roasting and reduction, and publish many articles. However, what device is used to better realize the roasting reduction theory, and what device is used to perform the roasting reduction thermal reaction of solid-phase minerals and gas-phase reducing agent. Therefore, the technical problem that needs to be solved urgently is to build an affinity "secret chamber" for all molecules of minerals and reducing agents, and to achieve the effect of molecular affinity curing by regulating the pressure difference change and temperature in the "secret chamber". It is feasible in principle, reliable in technology, reasonable in structure, and suitable for large-s...
