【摘要】 以冷却塔出口水温作为性能指标,提出了冷却塔运行经济性诊断模型和性能变化的定量计算方法,指出淋水填料损坏、内部组件结垢和配水分布不均是导致冷却塔性能下降的主要原因,利用麦克尔方程的二维数值计算方法,首次实现了喷嘴损坏对经济性影响的定量计算,并利用冷却塔经济性诊断的数学模型,解决了淋水填料损坏、脱落,塔内结垢对经济指标影响的定量诊断。更多还原

【Abstract】 Taking the water temperature at the outlet of cooling tower as performance index, the thermo-economics diagnosis model and the quantitative calculation method of cooling tower are put forward. The main reasons about performance declination on the cooling tower are the damage of spay packing materials, the fouling of the inner component and the uneven water distribution. With two-dimensional numerical calculation method of the Markel equation, quantitative calculation on the influence of the damage of spay packing materials on the economics is conducted at first. Moreover, with the mathematical model for cooling tower performance calculation, problems of quantitative diagnosis on the influence of the spray packing material damage, falling off and fouling on the economics are solved.更多还原
