The benefits of increasing the hot air velocity of a three-cylinder dryer
Reasons for various problems in the slime dryer During the drying process of the material in the dryer cylinder, its heat transfer efficiency will directly determine the degree of drying effect of the material. Based on years of experience, Linqu Sun has summed up the benefits of increasing the speed of hot air in the dryer.
1. Improve the hot gas flow of the dryer and increase the flow rate of the hot gas, which can increase the working efficiency of the lifting plate.
2. Improving the airflow speed of hot air plays a very important role in accelerating the heat speed.
3. To increase the velocity of hot air, it is necessary to design a reasonable exhaust air and dust removal system at the end of the dryer and a hot air supply system at the head end.

4. The total pressure and air volume of the exhaust fan must be appropriate. If the total pressure is too low and the air volume is too small, it will directly affect the exhaust air and reduce the output of the dryer; if the total pressure is too high and the air volume is too large, it will directly increase Power loss, and it will also increase the temperature of the exhaust gas off the machine, increasing the heat loss.
Fifth, to increase the insulation of the cylinder, use a boiling furnace for heating, and increase the temperature gradient.
6. The speed and flow of the hot air and the drying effect of the dryer will be directly induced during the operation. The drying speed of the dryer is also affected by the hot air. Controlling the hot air plays a decisive role in drying materials.
7. Strengthen the insulation of the cylinder body, use a boiling furnace for heating, and increase the temperature gradient by the temperature difference between the gas and the solid phase.
8. Increase the heating area of the solid phase.
9. The hot gas flow of the dryer increases the hot gas flow rate.
