冷却塔内纤维复合材料集水装置的材料性能设计与应用

Material Performance Design and Application of Fiber Composite Water Collecting Device in Cooling Tower

火电厂冷却塔安装除水器的目的是为了降低水损失,目前大部分除水器为聚氯乙烯材料制作的波纹板除水器,其易损坏脱落、寿命短,造成大量水资源的浪费。将除水器内上升的平直气流转为旋转气流,可在很大程度上提高收水效率,其对材料及成型工艺的要求也更高。文章针对冷却塔内气/液两相流的复杂环境,设计了一种纤维复合材料集水装置,采用对比实验进行研究。结果表明,制备的新型纤维复合材料旋流节水器较传统波纹板材料性能大幅优化,对于工业冷却塔节水优化提供了一种可靠的解决方案。

The purpose of installing dewaterer in the cooling tower of the thermal power plant is to reduce water loss.At present,most of the dewaterers are corrugated plate dewaterers made of polyvinyl chloride materials.It is easy to damage and fall off,with a short life,resulting in a large amount of waste of water resources.Converting the rising straight air flow into rotating air flow in the water separator will greatly improve the water collection efficiency,however,the requirement of material and forming technology is also higher.Aiming at the complex environment of gas-liquid two-phase flow in the cooling tower,the paper designed a water catchment device of fiber composite material,and carried out a contrast experiment.Research indicated that the performance of the new fiber composite swirl water-saving device developed in this paper is much better than that of the traditional corrugated plate water-collecting device,providing a reliable solution for water-saving optimization of industrial cooling tower.
