Double-chamber lime kiln with large treatment capacity
The invention relates to a double-hearth lime kiln with large treatment capacity. The double-hearth lime kiln comprises a double-hearth kiln body, feeding equipment, discharging equipment, an air supply system, a cooling air system and an exhaust emission system, the double-hearth kiln body is composed of an inner furnace wall located on the upper portion and an outer furnace wall located on the lower portion, an annular channel is arranged between the inner furnace wall and the outer furnace wall, and a smoke channel is arranged between the two kiln hearths. The top of the annular channel and the top of the flue gas channel are provided with arched tops, and the arched tops are made of magnesium aluminate spinel bricks. The sizes of the annular channel and the smoke channel are increased, and the smoke circulation amount of the annular channel and the smoke channel is increased. A wear-resistant lining is arranged on the inner wall of the upper portion of the inner furnace wall, and heat insulation materials are arranged between the wear-resistant lining and a shell of the upper portion of the inner furnace wall. The flue gas circulation amount of the annular channel and the flue gas channel is increased, so that the treatment capacity of the double-hearth lime kiln is increased. By improving the structures of the annular channel, the flue gas channel and the upper part of the inner furnace wall, the operation period of the kiln body is prolonged.
本发明涉及一种大处理量双膛石灰窑，包括双膛窑体、进料设备、出料设备、供风系统、冷却风系统和废气排放系统。双膛窑体由位于上部的内炉墙和位于下部的外炉墙构成，外炉墙与内炉墙之间设有环形通道，两个窑膛之间设有烟气通道。环形通道和烟气通道的顶部设有拱形顶，拱形顶的材质为镁铝尖晶石砖。加大环形通道和烟气通道的尺寸，扩大环形通道和烟气通道的烟气流通量。内炉墙上部的内壁装有耐磨内衬，耐磨内衬与内炉墙上部的外壳之间装有隔热材料。本发明通过扩大环形通道和烟气通道的烟气流通量，有利于扩大双膛石灰窑处理量。通过改进环形通道、烟气通道及内炉墙上部的结构，有利于延长窑体的运行周期。
