Characteristics and performance advantages of sludge dryer

Sludge dryer is a kind of energy-saving drying equipment, sludge dryer can be used for a variety of sludge drying treatment, because it has a strong thermal efficiency and the operation cost is very low, so the scope of use is very wide. Then let's take a look at the characteristics and performance advantages of sludge dryer.


1、 Characteristics of sludge dryer


1. Because the heat needed by the drying equipment is indirectly heated by heat conduction, a small amount of gas is not needed or needed to take away the moisture in the drying process. It greatly reduces the heat loss taken away by the air flow and improves the heat utilization rate. It is an energy-saving drying equipment.


2. Stirring and mixing make the materials turn violently, so as to obtain high heat transfer coefficient. Therefore, the floor area and space are very small, and the capital construction cost of the plant is saved. During the drying process, the amount of gas is less, the flow rate is low, and the amount of dust carried away by the gas is less, so the recovery of gas dust after drying is convenient, and the equipment investment can be saved. Due to the special structure of the blade, the material is squeezed and relaxed alternately during the drying process, which strengthens the drying.


3. Sludge dryer can be used for municipal sludge, printing and dyeing sludge, papermaking sludge, electroplating sludge and other fields of sludge drying, with high thermal efficiency, wide range of use, low operating cost, and continuous production.





2、 Characteristics and advantages of sludge dryer


1. Low energy consumption of sludge dryer: due to indirect heating, there is no large amount of air to take away heat, and the outer wall of the dryer is equipped with insulation layer, so the heat loss is very small.


2. The cost of sludge dryer system is low: the unit effective volume has a huge heat transfer surface, which shortens the treatment time. The size of the equipment becomes smaller and the floor area is reduced.


3. Wide range of materials to be treated: different thermal media can be used to treat heat sensitive materials and materials requiring high temperature treatment.


4. Small environmental pollution: carry little air, dust material entrainment is little.


5. Low operating cost: fully automatic control, no need for manual operation.


6. Stable operation: due to the special compression expansion stirring effect of the wedge blade, the material particles fully contact with the heat transfer area. In the axial range, the temperature, humidity, mixing temperature and gradient of the material are very small, thus ensuring the stability of the process. Yonggan energy saving technology focuses on the R & D and manufacturing of drying equipment, providing high-quality sludge dryer, sludge dryer, sludge dryer and other equipment, suitable for various types of sludge drying treatment.
