Sludge is a kind of domestic garbage, which has relatively great pollution and harm to the environment. It needs to be treated in time to avoid various problems. The current method is generally to dry the sludge, and then use it to produce fertilizer or use it as a gardening fertilizer. So what method is better for sludge drying?

  Sludge drying usually uses a drum-type sludge dryer for drying. This equipment uses the heat generated by fuel combustion as the drying medium to exchange heat with the wet sludge in the dryer to achieve the drying effect. However, there is a problem in the sludge drying process. When part of the sludge is dried, the outside will harden and form a larger diameter soil block, and the internal moisture is blocked by the external dry soil block and cannot evaporate, making it difficult to dry the sludge. The inside of the sludge dryer is equipped with lifting plates of different shapes, which can pick up these mud lumps during operation, rotate to a high place and fall, and the undried sludge inside the mud lumps is broken and leaks out, continue to be dried by hot air.

  The sludge dryer is suitable for drying sludge with a moisture content of less than 50%, this is due to the cost of drying. In fact, the dryer can dry sludge with any moisture, but sludge drying is a commercial activity, the cost and profit of the drying must be considered. Therefore, a reasonable process must be used to dry, so that customers have a certain profit margin, so the moisture content should be less than 50%. In addition, the use of sludge dryers must choose a suitable heat source, which can reduce costs and save energy and environmental protection, so that it will not affect the customer's income.

  The sludge drying method can also be dried naturally, but this method is inefficient, requires a larger leveling site, and is also restricted by weather and environmental factors, and the use conditions are more demanding, which many customers cannot use. Based on the existing drying technology, it is convenient and practical to use the sludge dryer to dry the sludge.
