Description

立式热回收焦炉荒煤气的引出方式  Leading method of vertical heat recovery coke oven waste gas
技术领域： Technical field:
本发明涉及一种立式热回收焦炉荒煤气的引出方式。  The invention relates to a method for extracting waste gas from a vertical heat recovery coke oven.
背景技术： Background technique:
立式热回收焦炉荒煤气产生之后， 从炭化室内煤饼以上的位置导出。 目前 生产中采取的导出方式只有两种。 第一种导出方式， 是一个炭化室产生的煤气 全部进入炭化室一侧的炉墙， 另一侧的炉墙的供热是靠相邻的炭化室来完成。 在端炭化室则荒煤气由双侧炉墙同时导下。 这种荒煤气的导出方式由于相邻两 个炭化室处在不同的结焦时段， 因而炭化室两侧的炉墙温度差异较大， 受到的 侧压力也不同。 不利于炼焦作业和炉体寿命。 所以被第二种导出方式取代。  After the vertical heat recovery coke oven waste gas is generated, it is derived from the position above the coal cake in the carbonization chamber. There are currently only two ways to export in production. The first type of derivation is that the gas produced by one carbonization chamber enters the furnace wall on the side of the carbonization chamber, and the heating of the furnace wall on the other side is completed by the adjacent carbonization chamber. In the end carbonization chamber, the waste gas is simultaneously guided by the double furnace wall. The method of deriving this kind of waste gas is because the adjacent two carbonization chambers are in different coking periods, so the temperature difference between the furnace walls on both sides of the carbonization chamber is large, and the side pressure is also different. Not conducive to coking operations and furnace life. So it was replaced by the second export method.
第二种煤气导出方式， 是将一个炭化室产生的荒煤气从两侧的燃烧室导出。 在导出口的设置上， 采取一侧炉墙的导出口与奇数火道相通， 另一侧炉墙的导 出口与偶数火道相通 （边炉墙除外）。  The second type of gas is derived by exporting waste gas from a carbonization chamber from the combustion chambers on both sides. In the setting of the outlet, the outlet of one side of the furnace wall is connected to an odd number of fire passages, and the outlet of the other side of the furnace wall is connected to an even number of fire passages (except for the furnace wall).
由此， 同一炭化室每侧炉墙中的燃烧室 (又称立火道)均由两个炭化室的煤气 相间供给， 使得炭化室炉墙温度的均匀性有所改善。 但炉墙温度仍存在有规律 的差别。  Therefore, the combustion chamber (also called the vertical fire channel) in each furnace wall of the same carbonization chamber is supplied by the gas phase of the two carbonization chambers, so that the uniformity of the temperature of the carbonization chamber wall is improved. However, there are still regular differences in furnace wall temperatures.
发明内容： Summary of the invention:
本发明的目的是解决现有同一炭化室的燃烧室相邻燃烧室 (又称立火道)由 不同炭化室供给煤气而存在温度较大差异的问题。  SUMMARY OF THE INVENTION The object of the present invention is to solve the problem that there is a large difference in temperature between the adjacent combustion chambers (also referred to as the vertical tunnels) of the same carbonization chamber in which the gas is supplied from different carbonization chambers.
本发明为解决上述问题而采取的技术方案：  The technical solution adopted by the present invention to solve the above problems:
立式热回收焦炉荒煤气的引出方式， 其特征在于： 每个燃烧室均有两个荒 煤气进口， 即原有的煤气出口和新增加的煤气出口， 并通向两个相邻的炭化室 (边燃烧室除外）。 本发明的碳化室用于存放煤。 燃烧室内为提供燃烧热量的荒煤气。 The method of extracting the vertical heat recovery coke oven waste gas is characterized in that: each combustion chamber has two waste gas inlets, namely the original gas outlet and the newly added gas outlet, and leads to two adjacent carbonizations. Room (except for the side combustion chamber). The carbonization chamber of the present invention is used to store coal. Inside the combustion chamber is a waste gas that provides heat for combustion.
本发明的有益效果是： 虽然每个燃烧室两侧的炭化室处于结焦的不同阶段， 产生的煤气量和品质各不相同， 但经过本发明的工艺方案使得进入每个燃烧室 中的煤气量和品质得到了进一步的均匀化， 因而各个燃烧室温度也更为一致， 使得炭化室中的焦饼受热更加均匀， 提高了焦炭的质量和产量， 同时保护了焦 炉炉体的结构， 有利于提高效益和延长炉体寿命。  The beneficial effects of the present invention are: although the carbonization chambers on both sides of each combustion chamber are in different stages of coking, the amount and quality of gas produced are different, but the amount of gas entering each combustion chamber is obtained by the process scheme of the present invention. And the quality is further homogenized, so the temperature of each combustion chamber is more consistent, so that the coke cake in the carbonization chamber is more evenly heated, which improves the quality and yield of coke, and at the same time protects the structure of the coke oven body, which is beneficial to Improve efficiency and extend furnace life.
