High-temperature gas treatment system for iron bath type smelting reduction furnace

The invention provides a high-temperature gas treatment system for an iron bath type smelting reduction furnace. The high-temperature gas treatment system comprises the iron bath type smelting reduction furnace, a pipeline type cooler, a primary dust remover, a cyclone dust removal unit, a waste heat recovery unit, a gas carrying buffer tank and various material blowing devices, and further comprises a blowing pipeline for connecting all the material blowing devices with the gas carrying buffer tank and the iron bath type smelting reduction furnace. The high-temperature gas treatment system aims to solve the problem of sensible heat recovery of high-temperature gas discharged out of the iron bath type smelting reduction furnace; secondly, a large number of iron-containing carbon materialscarried in the gas are recovered and reasonably utilized while the sensible heat of the high-temperature gas is recovered; and finally, the content of S in the gas is reduced as much as possible, andthe purpose of gas source
