Description
Technical Field
The invention relates to the technical field of inspection and analysis, in particular to a coal deterioration easily detecting sample storage combined device.
Background
The relevant data show that the coke productivity and the coke yield in China all account for about 70 percent of the global proportion. However, from the general situation of the global and Chinese coking coal resources, the global coking coal resources only account for less than 30 percent, and the Chinese coking coal accounts for 26.3 percent of the resources/reserves. The proportion of coal for coking in resources/reserves in China is less, only accounts for 1/4, and half of the coal is gas coal, while the strongly bonded fat coal and coking coal only account for 1/3 of the coal for coking, the coal for coking is also influenced by harmful components such as ash, sulfur, phosphorus and the like and selectivity, and the coal for coking can really serve as coking coal blending in resources/reserves which is less than 1/2. In the process of using precious disposable and non-renewable energy for a long time in the industry, the ratio of the high-quality main coking coal and the rich coal of the metallurgical coke is over 60 percent for a long time under the constraint of a coking and coal blending theory and the pressure of stable operation of a blast furnace. 1 ton of coke is smelted, and about 1.4 tons of fine coking coal are needed. And at least 2 tons of raw coal with better washing performance are needed for 1 ton of coking clean coal. Face the pressure of exhaustion of resource consumption. Related experts point out that the reserve and the use speed of the coking coal source coking coal, fat coal and the like in 2014 can be supported for about 50 years. But the reserves of the weak caking coal in China are rich, the research of strengthening the comprehensive utilization of the weak caking coal is important and urgent, the weak caking coal with rich reserves and low price is fully utilized, the comprehensive coal blending cost of the coking coal is reduced, the disposable resource is protected, and the method has great economic value and far-reaching social benefit.
The research and application of the coal blending coking test on the weak caking coal are continuously strengthened from the world to China in recent years, the weak caking coal is easy to oxidize due to the characteristics of deterioration times and coal formation processes in the coal blending coking test process, the sample retention time has large influence on the properties of the coal, and important adverse effects are generated on the research of the coal blending test, so that the objectivity, reality and accuracy of test detection data are restricted, the properties of the weak caking coal and the effect of the weak caking coal in the coal blending coking are difficult to scientifically and accurately judge, the serious influence is caused on the whole coal blending of a coking plant, and the coke quality and the coking comprehensive cost are directly influenced. The scientific and effective preservation of the coal sample which is easy to deteriorate, such as weak caking property and the like, becomes the biggest bottleneck restricting the coal blending coking test, and the coking test has the significance and the effect of guiding the actual production only if the truth and the objectivity of the sample coal sample are ensured.
