  三种干砂机的含水量是多少?
  What is the moisture content of three kinds of dry sand machines?
  1. 干砂设备采用黏液干燥,具有较低的含水率。黏液的含水率降低到20%左右甚至更少,比前一种方法降低了10%以上。好处是显而易见的。
  1. Dry sand equipment uses mucus drying, which has low water content. The water content of the mucus is reduced to about 20% or even less, which is more than 10% lower than that of the previous method. The benefits are obvious.
  在过去,煤泥进入选煤系统时有发生事故。煤泥被弃用的主要原因是混合煤泥含水率过高,形成较大的团块,造成问题。然而,随着黏液干燥机的成功研制,这些问题得到了解决。这表明了哪三个水位?进一步降低了泥水回用的可行性和现实性。
  In the past, accidents occurred when slime entered the coal preparation system. The main reason for the abandonment of slime is that the water content of mixed slime is too high to form larger aggregates, which causes problems. However, with the successful development of the mucus dryer, these problems have been solved. This shows which three water levels? It further reduces the feasibility and reality of sludge reuse.
  2,煤泥燃烧,含水量高达40%,煤炭的热值泥浆本身并不是太高,添加一定量的水,其热利用率大大降低,仅适用于小规模使用高质量的热煤浆利用率不高。

  2. Slurry combustion, water content as high as 40%, the calorific value of coal slurry itself is not too high, adding a certain amount of water, its thermal utilization rate is greatly reduced, only suitable for small-scale use of high-quality thermal coal slurry utilization rate is not high.
  3.将煤浆挤入流化床锅炉进行团聚燃烧。黏液的含水量可降低到32%至34%左右。与煤浆相比,水含量降低了近10%,锅炉燃烧效率非常高。热能的利用有了显著的改善,并得到了大规模的利用。这是大规模使用的先例。毕竟,黏液中仍然含有30%以上的水,而且水的热损失仍然很小。
  3. Push coal slurry into fluidized bed boiler for agglomeration combustion. The water content of mucus can be reduced to about 32% to 34%. Compared with coal slurry, the water content is reduced by nearly 10%, and the combustion efficiency of the boiler is very high. The utilization of heat energy has been significantly improved and has been used on a large scale. This is a precedent for large-scale use. After all, the mucus still contains more than 30% of the water, and the heat loss of the water is still very small.
