Abstract

The invention relates to a short process ferroalloy smelting device which comprises a radiation reducing furnace, a smelting raw material delivery system, a hot air delivery system, a fuel delivery system and a waste gas recovery system, wherein a semi-spherical furnace top is arranged at the upper part of the radiation reducing furnace; a spherical reflection plane is arranged in the semi-spherical furnace top; a sealed screw feeder is arranged at the top of the furnace body; a waste gas exhaust pipeline is arranged in the middle of the furnace body; a fuel spray gun is arranged at the lower middle part of the furnace body; a slag iron mixture discharge channel is arranged at the lower part of the furnace body; a mixing bin is erected above the radiation reducing furnace; two splitting pipelines are arranged at the bottom of the mixing bin; a feeding surge bin is arranged at the bottom of each splitting pipeline; the hot air delivery system comprises a blower, a hot air furnace and a hot air pipeline; the fuel delivery system comprises a fuel gas delivery pipeline, an air delivery pipeline and a heat exchanger; and the waste gas recovery system comprises a blister cooler, a dust catcher, an induced draft fan, a gas storage holder and a waste gas recovery pipeline.

Description

technical field [0001] The invention relates to a short-flow ferroalloy smelting device, which includes a radiation reduction furnace, a smelting raw material conveying system, a hot air conveying system, a fuel conveying system and a waste gas recovery system. A spherical reflective surface is arranged in the furnace top. Background technique [0002] In the prior art, there are high energy consumption and high pollution problems in the iron and steel industry. The waste heat emission loss of the iron and steel industry accounts for about 38.5% of the total energy consumption, and the physical waste heat of various products accounts for 29-39% of the total energy consumption. Among them, coking waste gas Sensible heat, sensible heat of coke, sensible heat of sinter, sensible heat of sintering flue gas, sensible heat of blast furnace gas, etc. account for a large proportion, and the ironmaking system accounts for 46% of the total energy consumption of the iron and steel indu...
