Description
技术领域technical field
本实用新型涉及煤炭转化测定装置，特别是一种炼焦煤膨胀压力测定装置。The utility model relates to a coal conversion measuring device, in particular to a coking coal expansion pressure measuring device.
背景技术Background technique
室式焦炉取代蜂窝式焦炉后，煤料在炭化过程中因煤种不同会产生不同程度的膨胀压力，造成推焦困难甚至损坏炉墙，缩短焦炉使用的寿命。当前被焦化工作者普遍接受的膨胀压力测定装置是带移动炉墙的实验焦炉，这类实验焦炉按装煤量可分为40kg、200kg、300kg，既一侧炉墙为固定炉墙，另一侧为可移动炉墙，通过可移动炉墙将炼焦过程中煤料对炉墙的膨胀压力表现出来，再由仪表进行检测。这类焦炉可以很好的检测出煤料在炼焦过程中的膨胀压力。但这类焦炉属于实验室水平，普遍存在装煤量较多，单炉操作时间长，装煤出焦工作量较大等缺点。After the chamber-type coke oven replaces the honeycomb coke oven, the coal material will have different degrees of expansion pressure due to different coal types during the carbonization process, resulting in difficulty in coke pushing and even damage to the furnace wall, shortening the service life of the coke oven. At present, the expansion pressure measurement device generally accepted by coking workers is the experimental coke oven with movable furnace wall. This type of experimental coke oven can be divided into 40kg, 200kg, and 300kg according to the coal loading. The furnace wall on one side is fixed. The other side is a movable furnace wall, through which the expansion pressure of the coal material on the furnace wall during the coking process is displayed, and then detected by the instrument. This type of coke oven can well detect the expansion pressure of the coal material during the coking process. However, this type of coke oven belongs to the laboratory level, and there are generally disadvantages such as a large amount of coal charging, a long operation time of a single furnace, and a large workload of coal charging and coke removal.
