一种大型回转窑系统及其煅烧硅藻土的方法
摘要：
本发明公开了一种大型回转窑系统及其煅烧硅藻土的方法，回转窑系统包括预热器、回转窑、冷却窑和五通道煤粉燃烧器，预热器与回转窑之间设有喂料管，回转窑与冷却窑之间设有出料管，回转窑的斜度为3～4％，冷却窑的斜度为4～5％，冷却窑连接有气冷式罗茨真空泵，五通道煤粉燃烧器连通回转窑的一端；煅烧硅藻土的方法包括如下步骤：(a)预备仪器；(b)加料预热；(c)煅烧成型；(d)成品冷却；(e)烟气吸收。本发明可用于连续化煅烧作业，性能可靠，产量高，煅烧效果好，工艺简单，分布有序，设备运行可靠，易于控制，生产线运转率高，节能环保。
摘要（英）：

The invention discloses a large rotary kiln system and a diatomite calcining method thereof. The rotary kiln system comprises a preheater, a rotary kiln, a cooling kiln and a five-channel pulverized coal burning machine, a feeding pipe is arranged between the preheater and the rotary kiln, and a discharging pipe is arranged between the rotary kiln and the cooling kiln; the slope of the rotary kiln is 3-4%, the slope of the cooling kiln is 4-5%, an air-cooled Root's vacuum pump is connected to the cooling kiln, and the five-channel pulverized coal burning machine is communicated with one end of the rotary kiln; the diatomite calcining method comprises the steps of instrument preparation, material adding and preheating, calcining and moulding, finished product cooling and smoke absorption. The large rotary kiln system can be used for continuous calcining operation, is reliable in performance, high in yield, good in calcining effect, simple in technology, ordered in distribution, reliable in device running, easy to control, high in production line running rate, energy-saving and environmentally friendly.
