An environment-friendly load test coke oven and its application method

Abstract

The invention relates to an environment-friendly load test coke oven and a method for using the same. The environment-friendly load test coke oven includes a test coke oven, a condensation recovery device for coking by-products and a moving device for coke pot components. The coke tank assembly consists of a coke tank, a coke tank cover, a load weight, a fiber insulation sleeve and a handle sleeve. The coke tank assembly can be lifted and rotated by the coke tank assembly moving device; the coking by-product condensation recovery device includes Shell and tube condenser, coal tar collection bottle, filter and electric igniter. The test coke oven of the present invention simulates production coke ovens with different volumes by adjusting the carbonization coking method of the coal blending sample load, and the coking by-products produced in the carbonization process can be fully recovered, so the coke, coal tar and coke of the coal blending can be obtained. It can also provide a coke sample for inspection that is consistent with the coking effect of coke oven carbonization in production, and make a complete and accurate evaluation of the coking effect of different coal blending carbonization.

Description

technical field [0001] The invention relates to the technical field of physical and chemical performance detection of metallurgical coke, in particular to an environment-friendly load test coke oven and a use method thereof. Background technique [0002] The test coke oven is designed according to the principle of similarity. In the coke cake of the carbonization chamber of the coke oven produced by coking, a representative shape unit is taken as the research object, and a series of conditions in the coking production process are simulated to study the coking mechanism, Experimental research on coke physical and chemical properties and other related indicators, from which to explore the experimental rules, summarize the optimal raw material ratio, and guide on-site production with high-quality, low-consumption raw material formula. The test coke oven should be scientifically, rigorously and precisely designed to ensure the authenticity, accuracy and reproducibility of parall...

Problems solved by technology

[0003] However, at present, the purpose of testing coke ovens at home and abroad is limited to a single test of coal blending dry distillation coking experiment, to complete the inspection of the cold strength, thermal reactivity and post-reaction strength index of coal blended coke. Colloidal natural expansion) under the condition of dry distillation coking method, the coke produced by the test coke oven has a lower density compared with the large coke oven, and there is too much coke, and the cold strength, 1100 ℃ reactivity and post-reaction strength indicators have relatively large deviations. The physical and chemical properties between the two can only be compared and measured by correlation, especially the by-products of the dry distillation process, oil gas and coal gas, are directly discharged into the atmosphere, causing certain pollution to the environment

Due to the large deviation and low reliability of the test results of the current experimental coke oven retort coking process, it is difficult to meet the needs of coking production guidance, and it is impossible to make a complete evaluation of the coking effect of coal blending retort distillation
