1.移动床交換塔树脂层高度选择: 移动床交換高度与交換流速和水质质量有关,一般采用1米,当然尚未起反应的树脂层高些好,但太高不仅增加树脂用量,也增加压头损失。我们认为:包括保护层树脂总高度选择1.0～1.2米左右,认为是较好的。这样树脂工作交換容量比较充裕,在生产中如发生流速突然增大,再生供盐不足或操纵不当等事故时,出水质量仍可保证,树脂层状态也可以较快恢复,从而保证生产。
1. The height of the resin layer of the moving bed exchange tower is selected: The exchange height of the moving bed is related to the exchange flow rate and the quality of the water quality. Generally, 1 meter is used. Of course, the resin layer that has not reacted is higher, but too high not only increases the amount of resin, but also increases the pressure. Loss of head. We believe that the total height of the protective layer resin is about 1.0 to 1.2 meters, which is considered to be better. In this way, the exchange capacity of the resin is relatively abundant. In the event of an abrupt increase in the flow rate during production, a shortage of regenerated salt, or improper handling, the quality of the effluent can still be guaranteed, and the state of the resin layer can also be restored quickly to ensure production.
