1. In order to increase the output, the dryer drum is too long; the diameter is too large; it cannot be fully utilized; the heat energy is lost; the equipment covers a large area.
2. In order to increase production, the inlet temperature is too high; the outlet temperature is too high; causing energy waste. At the same time, the quality of the material to be dried is also reduced; the color of the material is severely black; and even the paste is many.
3. The wind speed in the drum is too low, which causes the dynamic and static contact strength of the material and the hot air to relax, which results in low efficiency of the drying equipment.
4, only the downstream drying, and the saturated water vapor in the drying process can not be discharged in time, so that the water vapor running distance in the drum is too long, causing the water to be reabsorbed by the dry material.
5. The material does not “reciprocate†in the drum (the “reciprocating motion†and “square fast multi-loop motion†of the material in the equipment are two different concepts of our process flow). Therefore, the material in the drum is quickly taken away by the wind, and as a result, the storage amount of the material in the drum is too low, resulting in a decrease in the dynamic and static contact area between the material and the hot air.
6. In order to limit the flow speed of the material in the direction of the outlet, only the rotation speed of the drum is limited to be low, so that the number of times the material in the drum is lifted is also greatly reduced. As a result, the number of dynamic contact between the material and the hot air is greatly reduced.
7. The main unit of the drying equipment is installed in a tilted form with a high fire end and a low fire end. It is an extreme error. Because this installation method can only speed up the flow of material to the far fire end, so that the storage of the material in the drum is once again reduced, and thousands of lifting plates in the entire drum are raised at the same time from front to back, but the The material has been prepared very little. For example, a traditional dryer with a length of more than 20 meters can see a clear flame when it is seen from the main observation port during normal production. This indicates that there is little material in the drum, the space utilization of the drum is very low, and a large amount of heat is lost in vain. At the same time, this design creates unnecessary obstacles to the installation of the equipment and the operation of the equipment. Because the tilting angle of the mainframe must be installed with a set of anti-slip rollers to fix it to prevent the equipment from slipping during operation, it is very troublesome.
