How to effectively improve the working effect of the lignite dryer, we should first work on the operation of the lignite dryer. When we operate the lignite dryer, we should avoid those problems:
1. When operating the lignite dryer, we should first grasp the wind speed in the drum of the lignite dryer. If the wind speed is too low, the dynamic and static relaxation of the lignite and hot air will be made, and the drying efficiency of the lignite dryer will be reduced. .
2. It should be avoided that the lignite does not "reciprocate" in the lignite dryer cylinder, so that the lignite is quickly sucked away by the wind, making the storage capacity of the material in the lignite dryer drum too low, reducing the dynamic and static of the material and the hot air War area.
3. In order to increase the output of the lignite dryer, the length of the dryer drum cannot be lengthened. If the diameter of the lignite dryer is too large, it will not be fully utilized, which will cause heat loss and increase drying. machine equipment area.
4. When installing the main unit of the lignite dryer, please do not adopt the inclined installation method in which the fire end is high and the fire end is low. This installation method can only speed up the flow of materials to the far fire end and reduce the storage of lignite in the drum. Thousands of lifting plates in the entire drum from front to back are lifting materials at the same time, but there is not much material raised. This design has also caused unnecessary trouble to installation and operation in addition.
5. When the lignite dryer is not used for operation, it is not possible to only adopt the method of downstream drying. This drying method will make the saturated water vapor of the lignite during the drying process unable to be removed in time, and the running distance in the drum is too long. , so that the material absorbs water again.
6. The temperature of the material inlet and outlet should be well grasped. If the temperature of the material outlet is too high, it will cause energy waste. Also reduced the quality of being dried lignite simultaneously, make its color and luster seriously blacken even paste.
