Description
Technical Field

At present, a common countercurrent cooling tower uses a spray head to spray water onto the filler below, so that the heat exchange of water and wind is realized. The square countercurrent tower has small occupied area, can be designed in a modularized manner, and has an increasing share in the market. In the practical use of the countercurrent cooling tower, the cooling water pump frequency conversion technology is mostly adopted for saving energy, the power of the cooling water pump is regulated according to the change of the heat dissipation capacity, and when the required heat dissipation capacity is reduced, the power of the cooling water pump is correspondingly reduced, so that the water yield of the cooling water is reduced, and the purpose of saving energy is achieved; when the heat dissipation capacity is needed to be large, the power of the cooling water pump can be increased, the water quantity of the cooling water is increased, and the heat exchange requirement is met. However, most of the spray heads used in the square countercurrent tower are circular water inlet and are fixedly arranged above the filler, the spray range formed by spray water is circular, and if the edges of the spray ranges of the adjacent spray heads are too far apart, the phenomenon that the filler cannot spray water is easy to occur, so that the heat exchange performance of the cooling tower is affected. When the water pressure in the spray heads is reduced, the edges of the spray ranges of two adjacent spray heads are too far away, namely, when the water quantity of a cooling pump is reduced, more water-free gaps are formed on the packing of the cooling tower to influence the heat exchange effect of the packing, when the water pressure in the spray heads is increased, the phenomenon that the spray ranges of the adjacent spray heads are too much overlapped is easily generated, the water quantity in the overlapped area is more, the water quantity in the non-overlapped area is relatively less, the water quantity distribution of the packing below the spray heads on the same horizontal plane is uneven, particularly the spray heads arranged near the wall plates of the square cooling tower is easy to directly spray on the wall plates when the water pressure is high, and the heat exchange effect of the packing is influenced. Therefore, the existing spray head for the countercurrent tower has the defect that even spraying cannot be ensured in actual use, and needs to be improved.
