Wind in the case where ensureing that air inlet total amount is enough, reduces the requirement to the air blower blow rate required, so as to reduce disappearing for electric energy and filler
Consumption reduces air blast noise；
2nd, by setting bamboo hat shape retaining section in the top of main air inlet, it can effectively prevent that water droplet is fallen on when the blow rate required is small
In main air inlet；
3rd, by the way that water distributor is designed as form concentric spirals pipe, hot water can be made equably to be spilled into filler, effectively improves and change
The thermal efficiency；
4th, by helix tube outmost turns set tension part be fixedly connected with hot water manifold, can prevent helix tube long-time by
Gravity influences, and helix tube is caused to deform, and the periphery of helix tube is sagging.
5th, preferred mesh mist eliminator can not only filter out the larger liquid foam being suspended in air-flow, and can filter out smaller and micro-
Small liquid foam.

Specific embodiment
Below in conjunction with the accompanying drawings and pass through specific embodiment the utility model is described in further detail, following embodiment is simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
Specific embodiment 1
The utility model belongs to circulating water technical field, is related to a kind of venturi-type cooling tower, as shown in Figure 1,
Including tower body, tower body bottom is equipped with main air inlet 2, and the side wall of tower body lower part is equipped with side air inlet 3, is air outlet 8 at the top of tower body,
Tower body top is equipped with water distributor 6 and is connected with hot water manifold 5, and collecting-tank 9 is equipped with filled with filler 4, tower body bottom in the middle part of tower body,
9 bottom surface of collecting-tank is equipped with water outlet 91, and 8 lower section of air outlet is equipped with demister 7.
In the middle part of tower body and lower part is venturi-type structure, the venturi in the middle part of contraction section 11, tower body including tower body lower part
12 and diffuser 13.The venturi-type structure design of tower body in the utility model, can enable tower body by Venturi effect
Gravity-flow ventilation is efficiently used, reduces the requirement to the air blower blow rate required, power consumption is reduced, reduces noise.
Venturi effect：According to continuity equation, when gas or liquid flow inside Venturi tube, in pipeline
Most narrow place, speed reach maximum, and static pressure reaches minimum value；The speed of gas or liquid is because shove cross-section variation
Relation and rise, pipe reductions process will can be undergone in the same time by entirely shoving；Thus pressure also subtracts in the same time
It is small, and then pressure differential is generated, this pressure differential can be used for providing an external suction to fluid.For perfect fluid, the pressure
Difference is obtained by Bernoulli's theorem.
The operation principle of the utility model is as follows：
Air blower is opened, air is blasted from main air inlet 2, and air flows successively through the contraction section of venturi-type structure upwards
11st, venturi 12 and diffuser 13, because of Venturi effect so that generating pressure differential in contraction section 11 and venturi 12, side air inlet 3 will
Air sucking outside tower body, and flows up with the air that main air inlet 1 blasts, into tower body in the middle part of 12 He of venturi
In diffuser 13 in the filler of filling.At the same time, the hot water in hot water manifold 5 is spilled by the nozzle 61 on water distributor 6 and filled out
In material 4, meet with the upward air of adverse current and carry out heat convection；Current after heat exchange are fallen into collecting-tank 9, and from discharge outlet
91 discharges；Air after heat exchange continues uplink, after the processing of demister 7, filters out most moisture, is discharged from air outlet 8.
Demister 7 in tower body is set, more than 95% steam can be filtered out, effectively reduces moisture loss, solves cooling tower system
The problem of rate of water make-up of uniting is big.
Specific embodiment 2
The present embodiment is further optimized based on the above embodiments, and further is preferably to realize that this practicality is new
