  1、污泥干燥机设备结构紧凑,装置占地面积小。由设备结构可知,干燥所需热量主要是由排列于空心轴上的空心桨叶壁面提供,而夹套壁面的传热量只占少部分。所以单位体积设备的传热面积大,可节省设备占地面积,减少基建投资;
  1. Sludge dryer has compact structure and small area. According to the structure of the equipment, the heat required for drying is mainly supplied by the hollow blade wall arranged on the hollow axis, while the heat transfer of the jacket wall is only a small part. Therefore, the heat transfer area per unit volume of equipment is large, which can save the area occupied by equipment and reduce capital investment.
  2、污泥干燥机热量利用率高。污泥干燥机采用传导加热方式进行加热,所有传热面均被物料覆盖,减少了热量损失;没有空气带走热量,热量利用率可达80%以上;
  2. Sludge dryer has high heat utilization rate. Sludge dryer is heated by conduction heating, and all heat transfer surfaces are covered by materials, which reduces heat loss. Without air to take away heat, the heat utilization rate can reach more than 80%.
  3、污泥干燥机楔形桨叶具有自净能力,可提高桨叶传导作用。旋转桨叶的倾斜面和颗粒或粉末层得联合运动所产生的分散力,使附着于加热斜面上的污泥自动地清除,桨叶保持着更好的传热功能。另外,由于两轴桨叶反向旋转,交替地分段压缩(在两轴桨叶面相距近时)和膨胀(在两轴桨叶面相距远时)搅拌功能,传热均匀,提高了传热效果;

  3. The wedge blade of sludge dryer has self-purification ability, which can improve the conductivity of the blade. The dispersive force produced by the combined movement of the inclined surface of the rotating blade and the particle or powder layer makes the sludge adhering to the heating inclined surface be removed automatically, and the blade maintains an efficient heat transfer function. In addition, due to the reverse rotation of the two-axis blades, the mixing function of alternating compression (when the blade surface of the two-axis blade is nearest to each other) and expansion (when the blade surface of the two-axis blade is farthest from each other) can make the heat transfer uniform and improve the heat transfer effect.
  4、污泥干燥机由于不需要气体来加热,只需用少量气体来带走湿空气,干燥器内气速较低,被气体挟带出的粉尘少,干燥后系统的气体粉尘回收方便,尾气处理装置等规模都可缩小,节省设备投资.
  4. Sludge dryer does not need gas to heat, only a small amount of gas is needed to take away the wet air. The gas velocity in the dryer is low, and the dust carried by the gas is small. After drying, the gas and dust recovery of the system is convenient. The scale of the tail gas treatment device can be reduced and the equipment investment can be saved.
