  处理渣干燥机干燥物料过热的方法,这是初使用渣干燥机的用户经常遇到的问题,主要原因是操作还不熟练,没有在适当的地方掌握形成。以下是由烘干机技术员共同分享的渣式烘干机干燥物料过热是一个常见的问题,尤其是对热敏性物料。如果干燥后的物料质量发生变化,就会影响到生产的质量,有必要进行敏捷加工。
  The method of treating the excessive heat of the material in the slag dryer is a problem often encountered by the users who first used the slag dryer. The main reason is that the operation is not skilled and the formation is not mastered in the proper place. Following is a common problem, especially for heat-sensitive materials, in the slag dryer, which is shared by dryer technicians. If the quality of dried material changes, it will affect the quality of production, it is necessary to carry out agile processing.
  1. 干燥室内空气流速过低,外部雾滴主要在雾团干燥时干燥。由于雾团的初速度远大于气体的初速度,干粉在上旋开始后会进入高温区。
  1. The air velocity in the drying room is too low, and the external droplets are mainly dried when the fog is dry. Because the initial velocity of the mist is much higher than that of the gas, the dry powder will enter the high temperature zone after the start of the upper spin.
  解决方案:适当提高气速。通常在倒转时都装有一面镜子,从这里观察,如果上部气旋没有发生,说明气体流速是正常的。许多操作示例建议速度在0.5m/s左右。
  Solution: Increase gas velocity appropriately. Usually, when reversing, a mirror is installed. From here, if the upper cyclone does not occur, the gas flow rate is normal. Many operational examples suggest a speed of about 0.5m/s.
  2、排气温度过高,很多加仓矿渣烘干的货物都有排气,并终进行分离,所以排气温度的高低直接影响到商品的温度,它们之间的相对温差较大,通常排气温度比商品温度高10 ~ 30℃左右。如果尾气温度高,那么商品温度一定要高,超过商品温度的热量会使商品过热而变形。

  2. Exhaust temperature is too high, many goods dried by warehousing slag have exhaust gas, and eventually separated, so the exhaust temperature directly affects the temperature of the goods. The relative temperature difference between them is large. Usually the exhaust temperature is about 10 to 30 degrees higher than the commercial temperature. If the tail temperature is high, then the commodity temperature must be high. The heat beyond the commodity temperature will cause the commodity to overheat and deform.
  处理方法:控制干燥设备排气口温度,控制方法是降低热风进气口温度或增加喷淋量,使系统设置一个满意的排气口温度热平衡连接,保证货物的温度需求。
  Processing method: Control the temperature of the exhaust port of drying equipment. The control method is to reduce the temperature of hot air inlet or increase the amount of spray, so that the system can set up a satisfactory temperature balance connection of the exhaust port to ensure the temperature demand of the goods.
  3、操作渣干燥机前,操作人员应仔细了解设备的各个部位,知道如何操作,保护好,仔细阅读渣干燥机的操作规程,以免出现此类问题。
  3. Before operating the slag dryer, operators should carefully understand the various parts of the equipment, know how to operate and protect it, and carefully read the operating rules of the slag dryer in order to avoid such problems.
