Cement rotary kiln dust removal method

Cement rotary kiln is a kind of calcination equipment widely used in many production industries such as building materials,metallurgy, chemical industry and environmental protection.

Cement rotary kiln is a kind of calcination equipment widely used in many production industries such as building materials,metallurgy, chemical industry and environmental protection. However, the rotarykiln itself has a high temperature and is prone to dust pollution under hightemperature. But still need to be on the basis of the dust will not be removed.Let's take a look at the specific operation of the specific method!

1. Humidification tower. Under theinfluence of temperature, humidity, dust specific resistance and other factors,the new dry process kiln exhaust gas has a very low electrostatic precipitatingeffect. The humidifying tower can effectively reduce the overall temperature ofthe device and at the same time, reduce the dust pollution.

2. Pipe humidification. Pipelinehumidification technology in the kiln exhaust gas treatment bag filterequipment used more, or kiln cooling equipment exhaust cooling, this method ofexhaust cooling effect is smaller, usually 80-100 ℃.

3. Multi-tube cooling equipment.Specifically refers to the row after the grate cooler in the same number ofrows of steel tube, high temperature flue gas from the pipe through the use ofsurface heat pipe principle, through the tube to achieve the outer surface ofthe air-cooled heat exchange system, which Make the exhaust gas temperature inthe pipe lower.

4. Axial fan forced ventilation, this formof cooling is simple and reliable, and the effect is also very good.
