During the drying process of materials inside the three cylinder dryer, the heat transfer efficiency of the dryer directly determines the degree of material drying effect. Based on years of experience, the benefits of increasing the hot air flow rate of a three cylinder dryer have been summarized.
1、 Increasing the hot gas flow rate of the three tube dryer and increasing the flow rate of the hot gas can increase the working efficiency of the lifting plate.
2、 Increasing the velocity of hot air flow has a significant effect on accelerating the heating speed.
3、 To increase the speed of hot air flow, it is necessary to design a reasonable exhaust and dust removal system at the tail end of the dryer and a hot air supply system at the head end.
4、 The full pressure and air volume of the exhaust fan must be appropriate. If the full pressure is too low and the air volume is too small, it will directly affect the exhaust 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 the power loss and also cause the exhaust gas temperature to rise significantly, increasing heat loss.
5、 To increase the insulation of the cylinder, use a boiling furnace for heating and increase the temperature gradient.
6、 The speed, flow rate, and drying effect of the three tube dryer are directly sensed during operation, and the drying speed of the dryer is also affected by the hot air flow. Controlling the hot air flow plays a decisive role in drying materials.
7、 Strengthen the insulation of the cylinder, use a boiling furnace for heating, change the temperature difference between the atmosphere and solid phase, and increase the temperature gradient.
8、 Increase the solid heating surface area. Increase the hot gas flow rate of the dryer and increase the hot gas flow rate.
