| titleOfInvention | A kind of preheating and pre-reduction equipment and system suitable for smelting reduction process |
| abstract | The present application provides a preheating and pre-reduction equipment and system suitable for smelting reduction process. The equipment includes an equipment body, a pulverized coal injection element, a primary combustion device, a secondary air injection element, a temperature detection element, a control element and a secondary air injection element. Secondary combustion device; a reaction chamber, a feeding end and a discharging end are arranged in the equipment body; the pulverized coal injection element and the primary combustion device are arranged at the head of the reaction chamber; the secondary air injection element and the temperature detection element are arranged in the middle and Output air volume and temperature signal; the control element receives the air volume signal and temperature signal to adjust the working state of the pulverized coal injection element and the secondary air injection element; the secondary combustion device is arranged at the end of the reaction chamber, including the tertiary air injection element and dust Settlement chamber. By controlling the amount of pulverized coal injection, secondary air volume and multiple combustion, the equipment can make the heat distribution inside the equipment evenly, improve the heat utilization rate and the material pre-reduction rate; no supplementary fuel is needed; the recovered fine powder can be reused, reducing resources waste. |
