摘要

采用大型湿式逆流冷却塔的火电厂

冷却塔耗水量占全厂总耗水量的65%~75%

但目前普遍使用的传统节水装置仅能回收利用极少部分水损失。本文研究了采用离子风原理从冷却塔水汽中回收水的可行性。在实验室建立了冷却塔水汽回收的模拟实验装置

对一个多线-筒式收水单元的水回收率和电损耗开展了测试

研究了电压、放电电极形式、电极高度和接地电极材料等参数对于水回收率的影响。优化参数后在实验室中实现了90%以上的水回收率

平均每度电可以回收1.13 t水。根据实验得出的优化参数

提出了一种蜂巢式的收水装置概念。该装置经济效益和环保效益显著

具有一定的推广价值。

Abstract

The large wet-type counter flow cooling tower in thermal power plant consumes 65% to 75% of the total water consumption of the entire plant. However

conventional water-saving devices that are commonly used now can only recover a small portion of the water loss. This paper studies the feasibility of recovering water from the water vapor in the cooling tower using the ion wind principle. In the laboratory

a simulated experimental device for the water recovery from water vapor in the cooling tower is established. The water recovery rate and electrical loss of a multi-lined-cylinder water collection unit are tested. The effects of parameters such as voltage

discharge electrode form

electrode height

and ground electrode material on water recovery rate are investigated.After optimizing the parameters

the water recovery rate can reach up to more than 90% in the laboratory. And on average

1.13 tons of water could be recovered per kilowatt hour. According to the optimized parameters obtained from the experiment

a honeycomb-type water collection device concept is proposed. This device has remarkable economic and environmental benefits

which has a certain promotion value.
