Experimental coke oven for small-scale production of coke and colloid layer samples and using method thereof

Abstract

The invention relates to an experimental coke oven for small-scale production of coke and colloid layer samples and a using method thereof. The experimental coke oven comprises a heating furnace, a reactor and a colloid layer sampler; the heating furnace is composed of a furnace shell, a heating furnace body, a carbonization chamber and a top split furnace door which are sequentially arranged fromoutside to inside; heating devices are arranged in the heating furnace body at the two ends of the carbonization chamber respectively; the reactor used for containing coal samples is arranged in thecarbonization chamber and is divided into a main reaction region and a colloid layer sampling region, and the main reaction region and the colloid layer sampling region are respectively close to two heating ends of the heating furnace body; and the colloid layer sampler is movably arranged in the colloid layer sampling region; and the top of the reactor is provided with a reactor upper cover, thereactor upper cover is provided with a gas outlet, a plurality of temperature sensors and a pressure sensor. The experimental coke oven can be used for accurately simulating the working conditions ofa large coke oven, and preparing the colloid layer samples and the coke samples for coking of single coal seed or coal blending; and meanwhile a colloid layer can be sampled at any time, and the experimental coke oven is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of coking experiments, in particular to an experimental coke oven used for small-scale production of coke and colloidal layer samples. Background technique [0002] Coke is used as fuel, reducing agent and carburizing agent at the same time in metallurgical blast furnace, and also plays the role of column skeleton. The quality of coke has an important influence on improving blast furnace efficiency and improving steel performance. The quality of coke can be more accurately predicted by the colloid layer index (the maximum thickness of the colloid layer). The colloid layer index reflects not only the cohesive ability of coal but also the coking performance of coal, and is also an important index to distinguish the classification of bituminous coal. The colloid layer index can intuitively characterize the content of colloid in the blended coal. Too much or too little colloid content will affect the quality o...

Problems solved by technology

[0006] Therefore, the traditional experimental coke oven currently has technical defects, and cannot accurately simulate the coking conditions of industrial coke ovens under laboratory conditions, nor can it prepare coke and colloidal layer samples under industrial coking conditions.
