The invention discloses a
smelting system for accurately controlling harmful elements in
blast furnace molten iron, and relates to the technical field of
blast furnace smelting, the
system comprises the following components: an
atmosphere monitoring module, a parameter regulation and control module, a directional control module and a stable operation guarantee module; the
atmosphere monitoring module is used for monitoring the
atmosphere in the furnace in real time, including
oxygen content and
carbon monoxide content parameters, and is provided with a high-precision gas detection sensor to ensure accurate measurement of the atmosphere in the furnace; according to the method, the atmosphere change in the
blast furnace is monitored in real time, key parameters such as temperature, pressure,
air volume and material speed in the
smelting process are automatically adjusted according to the monitored data, the oxidation-reduction reaction in the blast furnace is optimized through the accurate
control mode, and therefore the content of harmful elements such as
sulfur and
phosphorus in molten iron is effectively reduced, and meanwhile the production cost is reduced. And the directional control module can spray corresponding reducing agents or adsorbents aiming at specific harmful elements, so that the removal efficiency of the harmful elements is further improved.
