Cooling tower is an important cold end equipment in power plant
of which its cooling performance directly affects the cyclic efficiency. Crosswind is a very common environmental condition in the working process of the cooling tower. It may harm the ventilation of the cooling tower
affect the uniformity of the aerodynamic field in the tower
resulting to the deterioration of the working performance of the cooling tower. Reasonable non-uniform arrangement of the fillers in the cooling tower is helpful to give full play to the cooling performance of the fillers to optimize the working effect of the cooling tower. A natural ventilation countercurrent wet cooling tower of a power plant is taken as the research object
and the influence of non-uniform arrangement on the performance of the cooling tower under crosswind conditions and the influence of different crosswind speed on the performance of the cooling tower under the optimal arrangement is studied by numerical simulation. The simulation results show that the non-uniform arrangement of the packing area can effectively improve the ventilation in the tower under crosswind conditions and reduce the outlet temperature. Under the premise of a zone radius of 36.77 m
the packing area is arranged with equal spacing and unequal height
and with unequal spacing and unequal height
respectively. The calculations show that the outlet temperature is reduced by 0.5 K and 0.7 K
respectively
compared to when the packing is uniformly arranged. At this zone radius
as the crosswind speed increases
the cooling tower"s outlet water temperature shows a trend of first increasing and then decreasing.
