Example one

As shown in fig. 1 and fig. 2, the water-saving noise-reducing anti-icing structure for the air inlet of the cooling tower in the embodiment includes a cross flow packing layer 1 disposed at the air inlet of the cooling tower in a matching manner and a flow guide layer 2 integrally disposed outside the cross flow packing layer 1, wherein the cross flow packing layer 1 completely shields the air inlet of the cooling tower; the 1 top-down of crossing current packing layer lets in the shower water, and is concrete, and crossing current packing layer 1 is located cooling tower packing layer 3's vertical projection area, and the rivers that flow in 3 both sides of cooling tower packing layer directly get into crossing current packing layer 1, have a plurality of outer high interior low airflow channel 4 in the diversion layer 2, and airflow channel 4's both sides are linked together with external atmosphere and crossing current packing layer 1 respectively, and airflow channel 4's cross section is regular hexagon.

The working process of the embodiment is as follows:

external air flows into the cross flow packing layer 1 from outside to inside through the airflow channel 4, meanwhile, spray water is introduced into the cross flow packing layer 1 from top to bottom, due to the fact that the temperature of the spray water cooled by the cooling tower packing layer 3 is low, in hot summer, the external air and the spray water generate heat exchange, the external air is purified after being contacted with the spray water, the temperature is reduced, the humidity is increased, the evaporation rate of main spray water in the cooling tower can be reduced when the external air in the state enters the cooling tower again and is contacted with the main spray water in the cooling tower packing layer 3 for heat exchange, water saving, emission reduction and fog dissipation of the cooling tower are facilitated, and the spray water in the cross flow packing layer 1 finally flows downwards into a cooling tower water tank; because of the application of the cross flow packing layer 1 and the diversion layer 2, circulating water drops and evaporation condensate water drops do not float out in a large amount from the air inlet of the cooling tower, so that waste of water resources and adverse effects on the surrounding environment and equipment are avoided, the ice formation hidden danger is avoided in winter, the safety production is facilitated, meanwhile, the outward transmission of rain noise in a rain area is weakened, the noise pollution is avoided, and multiple purposes are achieved.

Example two

As shown in fig. 3, the difference between this embodiment and the first embodiment is that the crossflow packing layer 1 is located outside the vertical projection area of the cooling tower packing layer 3, and a spray pipe 5 is arranged above the crossflow packing layer 1, the spray pipe 5 is communicated with a cooling tower supplement water pipe or a cooling tower return water bypass water pipe through a communication pipe 6, cooling tower supplement water flows in the cooling tower supplement water pipe, cooling tower circulating water which is filtered by bypass flows in the cooling tower return water bypass water pipe, a drain pipe 7 is further connected to the spray pipe 5, the drain pipe 7 is communicated with the cooling tower water tank for directly introducing water in the cooling tower supplement water pipe or the cooling tower return water bypass water pipe into the cooling tower water tank, valves are respectively arranged on the drain pipe 7 and the communication pipe 6, the valve on the communication pipe 6 is arranged close to the spray pipe 5, and the valve on the drain pipe 7 can be closed and opened when the spray pipe 5 needs to be repaired or the cooling tower water is directly drained into the cooling tower water tank, the other parts of this embodiment are the same as those of the first embodiment, and are not described herein again.

When the spray water is return water bypass water, the amount of circulating water entering the cooling tower can be reduced, and the reduction of the amount of circulating water means the reduction of the energy consumption of a circulating water pump of the cooling tower, so that the reduction of the power consumption is facilitated;

when the spray water is used as the cooling tower make-up water, because the initial temperature of the cooling tower make-up water is low, in hot summer, the external air and the spray water generate heat exchange, the external air is purified after being contacted with the spray water, the temperature is reduced, the humidity is increased, the external air in the state enters the cooling tower again and can reduce the evaporation rate of the main spray water in the cooling tower when being contacted with the main spray water in the packing layer 3 of the cooling tower for heat exchange, and the water saving, emission reduction and fog dissipation of the cooling tower are facilitated.
