Specific implementation mode
In order to make the utility model technology implement, technical solution and advantage are more clearly understood, below in conjunction with attached drawing, to this
Utility model technology is further elaborated.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of reverse-flow cooling tower geomantic omen matching enhanced heat exchange system
System includes tower body and supports the holder of tower body, and mounting bracket is arranged in tower body, and setting is except water layer 1 at the top of mounting bracket, except in water layer 1
Equipped with PVC dehydraters, the generation of winged water phenomenon is can effectively prevent, avoids the loss of liquid water, saves water resource.Except water layer
1 lower section setting sprinkling layer, sprinkling layer are used for spraying cooling circulating water.It sprays and packing layer 2 is set below layer, setting in packing layer 2
PVC packings, PVC packings can increase the heat dissipation area of water, extend cold wind path, improve the cooling effect of cooling tower
Fruit.
The mounting bracket includes support column 3, and according to the size of tower body, the support column 3 of different number, the support column is arranged
3 both sides are equipped with guide duct 4, and tower body center is directed toward in 4 one end of the guide duct, and the other end extends outside tower body, and guide duct 4 stretches out tower
External length is 500mm-1000mm.Guide duct 4 can active wind-guiding, the air outside tower body is imported into tower body inside
The diameter in heart district domain, guide duct 4 is generally 300mm-2000mm.Quilt for a long time is needed since guide duct 4 stretches into the part in tower body
Current scour, the guide duct 4 stretch into the portion of upper surface in tower body and are equipped with resistance to erosion rubber layer, generally use resistance to erosion rubber
It is brushed 2-3 times on guide duct 4, can prevent guide duct 4 from being damaged by current scour.
