摘要
In order to study the influence of the parameters of the split-plates on the efficiency of the dry-wet rain zone cooling towers, and obtain the optimized parameters of the dry-wet hybrid rain zone, the three-dimensional numerical model of wet cooling towers was established in this paper, and the orthogonal optimization of the dry-wet hybrid rain zone of a super-large wet cooling tower was proposed. The results show that for the cooling tower studied in the paper, the best efficiency can be achieved with the split-plates with a total coverage area of 2797.08m2, an installation angle of 15°, a length of 30.9m, an installation height of 10.37m and a number of 4; within the researched range, the efficiency enhancement effect increases with the the total coverage area, length and installation height, increases first and then decreases with the increase of installation angle, and decreases first and then increases with the increase of the number of split-plates. The correlation analysis shows that the influence of the total volume of the dry zone on the temperature drop increment is higher than the total inlet area. The research can provide theoretical reference for the engineering application of dry-wet hybrid cooling mode in rain zone. ©2022 Chin.Soc.for Elec.Eng.
