摘　　要：为了控制雾羽和节约水资源,搭建了高位收水机械通风冷却塔热态实验系统,分别对外部冷却模块(干湿联合冷却塔)和内部凝雾模块(凝雾式冷却塔)的消雾、节水及热力性能进行对比分析,研究了环境温度、循环水进水温度及循环水量对冷却塔性能的影响。结果表明:干湿联合冷却塔和凝雾式冷却塔均具有消雾和节水能力,但实现二者的消雾和节水是以降低冷却塔冷却性能为代价的;与原塔相比,干湿联合冷却塔和凝雾式冷却塔的循环水温降约降低了1.5 K;干湿联合冷却塔和凝雾式冷却塔的消雾和节水性能受运行参数的影响很大,且凝雾式冷却塔的节水量和节水率高于干湿联合冷却塔。To control plumes and save water resources,a hot test system for high level water collection mechanical cooling tower was established for comparative analysis of the plume abatement,water saving and thermal performance of the external cooling module(dry-wet hybrid cooling tower)and the internal condensation module(condensation plume cooling tower).The impact of the ambient temperature,inlet circulating water temperature and circulating water flow rate on the performance of cooling towers was studied.Results show that dry-wet hybrid cooling tower and condensation plume cooling tower have plume abatement and water saving capabilities,which are achieved at the cost of cooling performance reduction of the cooling tower.Compared with the original tower,the circulating water temperature drop of dry-wet hybrid cooling tower and condensation plume cooling tower decreases by about 1.5 K.The plume abatement and water saving performance of the dry-wet hybrid cooling tower and the condensation plume cooling tower is greatly affected by the operating parameters,and the water saving amount and water saving rate of the condensation plume cooling tower are higher than those of the dry-wet hybrid cooling tower.
