  在煤泥干燥机干燥过程中,其传热效率将直接决定物料干燥效果的好坏。孙在多年经验的基础上,总结了增加热流速度干燥机的优点。
  In the drying process of the slime dryer, the heat transfer efficiency will directly determine the drying effect of the material. On the basis of many years'experience, Sun summarized the advantages of increasing heat flow rate dryer.
  首先,提高烘干机的热风流量,提高热风流量,可以提高给料板的工作效率。
  Firstly, increasing the hot air flow rate of the dryer and the hot air flow rate can improve the work efficiency of the feeder board.
  其次,增加热风流速对加快热风流速,具有十分重要的作用。
  Secondly, increasing the hot air velocity plays an important role in accelerating the hot air velocity.
  三、为提高热风流速,有必要设计合理的烘干机尾部排尘系统和头部末端加热空气系统。
  3. In order to improve the hot air flow rate, it is necessary to design a reasonable tail dust exhaust system and a heating air system at the end of the head of the dryer.

  四、抽风机满压时,风量一定要合适,如果满压过低,风量过小,会直接影响排风,降低烘干机的产量;如果总压过高,风量过大,会直接增加功率损失,从机器排出的废气温度会升高很多,增加热损失。
  4. When the exhaust fan is under full pressure, the air volume must be appropriate. If the full 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 the power loss, and the exhaust temperature from the machine will rise a lot and increase the heat loss.
  五、增加气缸的保温,使用沸腾炉加热,增加温度梯度。
  5. Increase the temperature of the cylinder, use the fluidized bed furnace to heat, increase the temperature gradient.
  热风的流动速度和干燥机的流动速度以及干燥效果在运行中会直接感应,干燥机的干燥速度也受热风流动的影响,控制热风流动对干燥物料起着决定性的作用。
  The flow speed of hot air, the flow speed of dryer and the drying effect will be directly induced in operation. The drying speed of dryer is also affected by the flow of hot air. Controlling the flow of hot air plays a decisive role in drying materials.
  七、加强气缸保温,采用沸腾炉加热,增加大气固相温差,提高温度梯度。
  7. Strengthen the thermal insulation of cylinder, use the fluidized bed furnace to heat, increase the temperature difference of atmospheric solid phase, and increase the temperature gradient.
  8. 增加固相加热面积。
  8. Increase the heating area of solid phase.
  增加热风干燥机的流量,提高热风的流量。
  Increase the flow rate of hot air dryer and increase the flow rate of hot air.
