High-temperature oxygen-rich heating furnace for extracting vanadium and titanium from vanadium-titanium slag and operation method of high-temperature oxygen-rich heating furnace

Abstract

The invention relates to a high-temperature oxygen-rich heating furnace for extracting vanadium and titanium from vanadium-titanium slag and an operation method of the high-temperature oxygen-rich heating furnace. The high-temperature oxygen-rich heating furnace comprises a heating furnace, a gas system, a combustion supporting air system, a smoke system and an oxygen-rich air system. The top of the heating furnace is provided with an auxiliary fire source and an electronic igniter. The heating furnace is provided with a combustion supporting air inlet connected with the combustion supportingair system and is provided with a gas inlet connected with the gas system. A smoke outlet is arranged and connected with the smoke system. An oxygen-rich air outlet is arranged and connected with an oxygen-rich air outlet pipeline, an oxygen-rich air inlet is arranged and connected with an oxygen-rich air inlet pipeline, and the oxygen-rich air inlet pipeline is connected with the oxygen-rich airoutlet pipeline through an oxygen-rich air branch pipe. The heating furnace is further provided with an upper thermometer, a lower thermometer and a heat storage body. By means of the high-temperatureoxygen-rich heating furnace for extracting vanadium and titanium from vanadium-titanium slag and the operation method of the high-temperature oxygen-rich heating furnace, the low-temperature oxygen-rich air can be heated into high-temperature oxygen-rich air needed for later vanadium extraction and titanium extraction, the integral technology requirement is met, finally, the vanadium and titaniumcontaining slag can be better resourcefully utilized, and environment pollution caused by metallurgy slag is reduced.

Description

technical field [0001] The invention relates to the technical field of metallurgical slag treatment, in particular to a high-temperature oxygen-enriched heating furnace for extracting vanadium and titanium from vanadium-titanium slag and an operating method thereof. Background technique [0002] my country's vanadium-titanium magnetite resources are mainly concentrated in the Panxi area of ​​Sichuan and the Chengde area of ​​Hebei. Vanadium-titanium magnetite is not only an important source of iron, but also associated with vanadium, titanium, chromium, cobalt, nickel, platinum group and scandium And other components, with high comprehensive utilization value. [0003] Vanadium-titanium magnetite produces a large amount of blast furnace slag and converter slag in iron and steel metallurgy, which are usually piled up in the factory area and become waste, which cannot be effectively utilized; it not only occupies the site, but also causes environmental pollution if it is not ha...
