Radio frequency linear plasma device and its application in smelting of vanadium titano-magnetite

Abstract

The application discloses a radio frequency linear plasma device and application thereof in vanadium-titanium magnetite smelting, and the device comprises an outer shell, a discharge chamber arranged in the outer shell, a neutralizer arranged at the top end of the outer shell, a radio frequency induction coil arranged in the outer shell and a heat exchange coil; the outer shell is provided with an air inlet joint and an air outlet joint; the bottom end of the discharge chamber is communicated with the air inlet joint, the top end of the discharge chamber is provided with a high-temperature-resistant pipe clamped with the air outlet joint, the neutralizer is communicated with the air outlet joint, the radio frequency induction coil is sleeved outside the discharge chamber, and the outer shell is provided with a radio frequency input joint connected with the radio frequency induction coil; the device has a reasonable structure design, adopts a ring-shaped radio frequency induction coil to replace a traditional induction electrode, can generate high-density plasma under a lower radio frequency voltage, greatly reduces energy consumption during device operation, and promotes efficient smelting of vanadium-titanium magnetite through the formed ring-shaped plasma, thereby obviously improving the content of titanium dioxide in smelted products, and thus has good market competitiveness.
