褐煤烘干机的干燥原理简单的说就是,物料进入筒体内通过扬料板等装置升起落下,与热气流接触,水分得到蒸发实现干燥。褐煤烘干机一般是采用顺流烘干工艺。从原理上我们就能看出、热气与物料的交换哈斯分关键。可以说决定着褐煤烘干机的干燥时长和***终的品质。都有哪些方面会影响到物料的热交换能力呢?
1、筒体内温度的高低 这个是***明显和直白的。在单位时间内、温度高的肯定干燥的更快、温度低的肯定就慢一些。所以褐煤烘干机筒体内的温度高低影响着物料与热气的交换能力。如果温度达不到、可能干燥的时间久会长、效率降低。
2、热气流通是否通畅 顺利干燥工艺也就是热气流运动的方向与物料运动的方向是一致的。在热气流运动的时候是否通畅很重要。假如出现了堵塞情况、热气流通就会不通畅、热交换的能力也就下降、从另一方面来说热量就损失了。物料与气流接触能力下降。
3、扬料板问题
褐煤烘干机筒体内的扬料板安装的意义就在于处理物料。通过筒体的不断旋转,扬料板对物料不断的扬起落下,在这一过程中,物料被均匀展开、扩大了与热气流的接触面积。所以干燥的也就变得高效。物料的热交换能力的高低与扬料板的设计有很大的关系。
Lignite dryer drying principle is simple, material into the cylinder body through the feed plate device sunrises, contact with the hot air flow, moisture to evaporate to get dry. Lignite dryer is usually adopts downstream drying process. In principle, we can see, the exchange of heat and material haas key points. Can determine the lignite dryer drying time and the final quality. What are the aspects will affect the heat exchange ability of the material? 1, the cylinder body temperature This is the most obvious and straightforward. In unit time, high temperature must dry faster, the affirmation of the low temperature is slower. So the lignite dryer cylinder body temperature influences the material and heat exchange capacity. If the temperature is not reach, may dry time, lower efficiency. 2, the heat flow is obstructed Direction of motion of the drying process is the heat flow smoothly with direction of motion of the material is the same. At the time of heat flow movement is obstructed
