Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a cement kiln tail exhaust fan for cement production. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly bind sand, stone and other materials together. For a long time, it has been widely used in civil engineering, water conservancy, national defense and other projects as an important cementitious material. In the process of cement production, tail gas is generated, and it is generally necessary to use a kiln tail exhaust fan to discharge the tail gas.

[0003] Most of the exhaust fans currently used are fixedly installed at the docking pipe for stable use, and it is not convenient to adjust their use position and use height to perform exhaust operations at different heights.

Compared with the existing device, the kiln tail exhaust fan for cement production can remove dust and tiny impurities in the gas through the filter screen plate and the activated carbon filter plate. The gas filter plate in the purification box is made of natural fiber and can absorb and intercept harmful components in the gas, so that it can remove dust while achieving the effect of purifying the gas, ensuring that the subsequent discharged gas does not affect the environment.
