Experimental device and method for performing on-line monitoring on lump coal splitting decomposition

Abstract

The invention provides an experimental device and method for performing on-line monitoring on lump coal splitting decomposition. The experimental device is mainly formed by a molybdenum disilicide furnace, a protective gas supplying device, a flue gas analyzer, an electronic balance, a corundum crucible and a monitoring computer. The experimental device is simple, practical and capable of performing on-line monitoring on quality changes and a gas generation rule in the fast decomposition process when the lump coal instantly enters high temperature from normal temperature. The obtained monitoring data can provide important theoretical foundation and technical basis for research directions such as how to optimize a blending structure, reduce bed pressure damage or reduce fuel consumption in the COREX process. By means of the experimental device and method for performing on-line monitoring on the lump coal splitting decomposition, carbocoal products of a lump coal splitting decomposition experiment can be conveniently extracted and can be further used for carbocoal industrial analysis and elemental analysis after being subjected to dry quenching of coke, and detection to strength and changes of coal rock structures, particle sizes, porosity, shapes, functional group structures and the like. Therefore, the experimental device and method for performing on-line monitoring on the lump coal splitting decomposition have wide application prospects.

Description

technical field [0001] The invention relates to the technical field of metallurgical engineering, in particular to an on-line monitoring experiment device for lump coal cracking and a method for using the experimental device to conduct on-line monitoring experiment for lump coal cracking. Background technique [0002] The blast furnace ironmaking process has a huge main body and auxiliary equipment, and consumes a large amount of high-quality coke. Due to the shortage of coking coal resources, the soaring price of coke and the characteristics of high energy consumption and high pollution in the coking process, ironworkers are forced to continuously research and develop new ironmaking processes and technologies. As a non-blast furnace ironmaking process, the COREX smelting reduction ironmaking process can directly use non-coking coal and lump ore into the furnace for ironmaking, and has the advantage of not using or using less coke. Compared with the blast furnace ironmaking ...
