Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to a coking experiment coke oven and a coking experiment method. Background technique [0002] In modern large-scale coking production, an important part of determining the quality of coke is coal blending. The quality of coal blending directly determines the quality of coke and the cost of coking production. When predicting the quality of coke and improving and determining the coal blending scheme, it is very necessary to conduct simulation experiments on the quality of coke produced in coke ovens. The important function of the experimental coke oven is to judge the feasibility of the coal blending scheme and predict the coke quality of the coke oven produced, so the accuracy and correlation of the experimental coke oven are particularly important. [0003] At present, the experimental coke ovens used by coking enterprises to guide the production of coal blending sc...

AI Technical Summary

Problems solved by technology

Although the experimental coke oven is constantly being optimized and improved, based on its structural form, even if the optimization is close to the extreme, it is still impossible to make the data of the experimental coke oven consistent with the data of the production coke oven

For example, the structural characteristics of the experimental coke oven determine that it is impossible to increase the amount of coal used in the experiment at will. Therefore, the height of the experimental coal sample is low, and the influence of the weight of the coal sample on the coke quality cannot be considered. There is always a deviation between them, which leads to limitations in the accuracy of the experimental coke oven, and only the correlation between the two can be used to predict the quality of coke

[0006] To sum up, most of the existing technologies for the accuracy and relevance of experimental coke ovens are based on methods such as improving the structural sealing of experimental coke ovens, simulating the gas pressure environment on the top of production coke ovens as much as possible, and automatically controlling the coking process. Continuously optimize the performance of the experimental coke oven. Although these technical solutions are conducive to improving the suitability of the experimental coke oven, they have not considered the impact of the coke quality change on the experimental results caused by the continuous increase in the capacity of the production coke oven. Therefore, it is necessary to Developed an experimental coke oven device and method that can actively respond to the current situation and development trend of coking production, effectively simulate the impact of coking coal weight changes, and improve the accuracy of experiments
