The utility model relates to a dry quenching furnace with a water-cooled support frame and an annular storage chamber, which consists of an annular storage chamber composed of an upper inner ring wall and an upper outer ring wall; a water-cooled support frame is arranged in the upper space of the cooling chamber, which comprises a plurality of crossbeams, and a pre-stored air passage and a water-cooled jacket are arranged in the crossbeam; and the materials under the lower inner tube, the inner ring top plate and the lower inner ring wall are enclosed into a closed space. The lower inner cylinder is connected with one end of each pre-stored airflow channel, and the other end of the pre-stored airflow channel is connected with the annular airway; the lower space of the cooling chamber is the material accumulation area; the water-cooled jacket is connected with the upper inner cylinder through the guide pipe, and the upper inner cylinder is equipped with a long-axis liquid pump and a float level meter. The long-axis liquid pump is controlled by a float level meter, and the outlet end of the long-axis liquid pump is connected with an external deaerator. The utility model can overcome the shortcomings of the conventional dry quenching furnace structure, reduce the material distribution segregation, reduce the high pressure at the top of the storage chamber caused by the material with large resistance per material layer, and reduce the resistance loss of the circulating gas.

技术介绍
干熄炉是焦化生产的一项重要节能环保设施,能够将从焦炉中推出的炽热焦炭在进行冷却的同时回收焦炭携带的大量热能,也避免了湿法熄焦对环境造成的水、气污染,因此在焦化领域得到了广泛应用。焦炉生产具有周期性和间歇性,且焦炉系统需要进行日常定期的检修(焦炉机械日最大检修时间达2h),因此焦炭装入干熄炉进行冷却的时间和频次受着焦炉生产的影响和制约;另一方面,干熄炉内冷却室焦炭的供给是需要连续稳定的,以便保障热能回收利用系统连续稳定运行。为了实现上述目标,通常在干熄炉的上部、冷却室的上方设置一个预存室,用于临时储备一定量的焦炭,适应焦炉日常定期检修的生产要求。常规干熄炉的预存室一般为圆筒形(如图1所示),物料从预存室顶部开口1-1周期地装入,在重力作用下自由落入预存室1-2,在预存室1-2的圆筒形空间内自然堆积形成顶部具有环形峰的物料层1-3,预存室1-2下部的物料呈圆柱形堆积并逐渐进入冷却室1-4。在预存室1-2下部,设有导出用于与炽热物料冷却的循环气体的环 ...
