Under the arrangement mode, the water mist at the outlet of the nozzle can only cover 3-4 fin cooling tube bundles in the direction opposite to the nozzle, and most of the fin cooling tube bundles are not covered by the water mist, so that the expected cooling effect is difficult to achieve.
In order to prevent freezing, when the whole system is stopped, water discharging operation is needed, and water is discharged conventionally by opening and closing a large number of valves (about 300 valves), which is time-consuming and labor-consuming; in addition, a high-voltage main transformer is arranged below the conventional air cooling island, and the main transformer can be caused to arc by one-time large-amount water drainage, so that the safe operation of the unit is threatened.
