  Drying and energy treatment principle of sludge dryer
  污泥处理原理:
  Sludge treatment principle:
  1,通过污泥干燥设备减少底泥的污泥量和含水量,综合利用运输,消化,脱水和创造条件,减少污泥处理。
  1. Reduce the sludge content and water content of the sludge through the sludge drying equipment, make comprehensive use of transportation, digestion, dehydration and create conditions to reduce sludge treatment.
  2,污泥健康稳定,污泥中含有大量有机物,各种病原体,重金属等有害物质,若不稳定处理将成为二次污染源,导致环境污染和病菌的传播。
  2. The sludge is healthy and stable. There are a lot of organic matters, various pathogens, heavy metals and other harmful substances in the sludge. If the sludge is unstable, it will become a secondary pollution source, leading to environmental pollution and the spread of pathogens.
  3,污泥处理原则:通过干燥改善污泥的成分和性质,促进污泥的使用。 总之,污泥处理的原则被减少,稳定,净化和资源化。
  3. Sludge treatment principle: improve the composition and properties of sludge through drying to promote the use of sludge. In short, the principles of sludge treatment are reduced, stabilized, purified and resourced.
  干燥机主要由加热污泥水蒸发,相变水分离组成。 同时,在传热和传质过程中,污泥中的液态水和内部物质移动并扩散到材料表面,蒸发或直接蒸发,迁移并扩散到表面。
  The dryer is mainly composed of heating sludge water evaporation and phase change water separation. At the same time, in the process of heat and mass transfer, the liquid water and internal substances in the sludge move and diffuse to the surface of the material, evaporate or directly evaporate, migrate and diffuse to the surface.

  Principles of dry energy treatment:
  污泥烘干机的热损失主要来自热源和干燥过程。 不同类型热源的热利用效率不同。 不同的工艺类型对热损失有很大影响。 当水含量高时,热传导通过热传递。 表面发生固液传热,传热效率高于热对流。 干燥后期的污泥进入“粘合相”阶段,此时热对流的传热效率高; 在干燥过程中干燥气体的反复冷凝,洗涤和加热过程具有大的热损失; 该过程的特征也决定了它的热量损失。
  The heat loss of sludge dryer mainly comes from heat source and drying process. Different types of heat sources have different heat utilization efficiency. Different process types have great influence on heat loss. When the water content is high, the heat conduction is overheated. The heat transfer efficiency is higher than that of heat convection. In the later stage of drying, the sludge enters the "adhesive phase" stage, at which the heat transfer efficiency of heat convection is high; in the drying process, the drying gas repeatedly condenses, and the washing and heating process has a large heat loss; the characteristics of the process also determine its heat loss.
