Embodiment 1

[0025] The technical problem to be solved by the embodiments of the present invention is to provide a feeding and conveying system for smelting reduction furnaces. , Dolomite powder feeding conveying system. The pulverized coal adopts 4 sets of stringing tank systems, which are fed through the dry coal bunker, tundish, and injection tank, and fed by the rotary feeder; Unloading, feeding by rotary feeder, connected to two pulverized coal injection pipelines nearby; iron ore powder and dolomite powder adopt 2 sets of series tank system, unloading through hot ore bin, intermediate tank, injection tank, screw feeding The material is fed by the feeder, and the material in the hot ore bin is iron ore powder and dolomite powder mixed in proportion, dried and heated powder. Using nitrogen as the carrier gas, the hot ore, coal powder, and flux pipelines are merged before entering the spray gun, and the injection pipelines of the three systems are finally merged into two pipelines in f...

Abstract

The invention discloses a feeding conveying system and method for melting reduction furnace. The system comprises a hot ore bin (1), an intermediate tank (2), a blowing tank (3), a spiral feeder (4),a quick lime powder bin (5), a rotary feeder (6), a dry coal bin (7) and a conveying pipeline (8), wherein an outlet of the hot ore bin (1) is connected to the conveying pipeline (8) through the intermediate tank (2), the blowing tank (3) and the spiral feeder (4) in sequence, an outlet of the quick lime powder bin (5) is connected to the conveying pipeline (8) through the intermediate tank (2), the blowing tank (3) and the rotary feeder (6) in sequence, and an outlet of the dry coal bin (7) sequentially passes through the intermediate tank (2), the blowing tank (3) and the rotary feeder (6) so as to be connected to the conveying pipeline (8).

Description

technical field [0001] The invention relates to a dust feeding and conveying system, in particular to a feeding and conveying system and method for a smelting reduction furnace. Background technique [0002] Blast furnace coal injection technology has been widely used in our country, and more and more blast furnaces adopt coal injection technology. my country's blast furnace coal injection technology and technology have developed to a relatively high level. At present, the state requires that coal injection systems must be installed in newly built or reconstructed blast furnaces. At present, only the coal injection system is used in the blast furnace process, but not only the coal injection system but also the ore injection system are required in the smelting reduction furnace. In addition, the entire injection system technology is not perfect, the powder cannot be fed normally, there are problems such as material blockage, unsmooth feeding, wrong powder sequence control, a...
