整个窑炉的温度分布监控对于水泥质量至关重要。它还可以通过在早期阶段检测耐火材料或未充分淬火的熟料来帮助延长窑炉的使用寿命——如果不加以控制,可能会导致生产停顿。

窑炉内的条件使得温度分布监控变得困难。窑炉旋转、高温以及烧结材料沿窑炉的移动使得热电偶和其他接触式温度传感器不太好用。非接触式温度测量方式就显得非常有价值。

HJK-FBTS-XC在线式防爆红外热成像监控系统(非接触式温度测量方式)位于燃烧器下方和侧面的窑头罩的观察口可以最好地测量熟料温度,这个位置温度高,粉尘大,设备配套水冷装置,以防止损坏设备。

HJK-FBTS-XC在线式防爆红外热成像监控系统功能特性:

  1. 采用非制冷焦平面探测器、高性能红外镜头、信号处理电路、并嵌入先进的图像处理算法,具备功耗低、启动快速、成像质量优异、测温精准等特点;
  2. It has all-weather passive thermal imaging function, has strong smoke penetration performance, and can be used in a wide range of ambient temperatures;
  3. Adopt self-developed temperature measurement correction algorithm to realize accurate temperature measurement;
  4. 防护罩采用耐高温合金材料制成,具有耐腐蚀、耐高温性能。窥孔直径2mm,在冷却介质及风吹扫后,在耐高温、防粉尘等性能方面更为优良,大大提高使用寿命;
  5. 在镜头前采用多道风屏,既可以起到降温的作用,更重要的作用是挡去了窑内的飞砂、熔融物等,使镜头不受污染和侵蚀,保持图象永久清晰;
  6. 对压缩空气采用空气净化器,始终保持镜头无污,保证图像清晰;
  7. 具有断水、断气、断电、温度高自动退出功能;
  8. 全自动进入功能,气压压力、水流量高于设定值,温度低于设定值,探头自动伸进窑炉监测炉内情况。

回转窑是水泥厂的核心设备;其工作状况直接影响水泥厂的生产效率和熟料质量。为了使回转窑保持良好的工作状态,我们必须学会在日常生产中如何正确维护回转窑。回转窑的维护有一些注意事项和说明。

水泥回转窑可能出现的故障有:

  1. 窑筒在长期的过程中可能会出现径向摆动变大,导致窑尾漏料严重的情况;
  2. 熟料生产过程中窑筒上下运动不受控制,会影响托辊、轮带的稳定性和使用寿命;
  3. 大齿轮、托辊振动异常,窑轮传动频繁振动,影响正常生产;
  4. 回转窑耐火衬砖经常开裂、脱落;
  5. 熟料生产过程中,窑的传递扭矩和各轮带支撑轴的承载力发生意外变化。
