Embodiment
To illustrate the thought and purpose of the present invention, the present invention is done further below in conjunction with the drawings and specific embodiments
Explanation.
First embodiment：
Reference picture 1-4, the present embodiment propose a kind of cooling tower with fair water cone 2, including tower 1, fair water cone 2 and reinforcer
3。
Fair water cone 2 is loop configuration, and the root of fair water cone 2 is arranged at the outer surface of tower 1, close to tower 1 air inlet and
It is arranged above air inlet, fair water cone 2 is in diminishing back taper annular from top to bottom.
The fair water cone tilted upward at the air intake open height of cooling tower tower 1 along one ring shape of the setting of cooling tower tower 1
2, the intake of cooling tower can be increased and improve the air fluidised form of air inlet.
With reference to figure 1, the development length that fair water cone 2 stretches out from tower 1 is L, and the height of air inlet is H, fair water cone 2
Lower surface is with the horizontal angle theta.
Specifically, angle, θ is acute angle；More specifically, angle, θ scope is：15 degree<Angle, θ<45 degree.Namely such as Fig. 1
Shown in Fig. 4, in terms of front, the profile of fair water cone 2 linearly tilts upward the outer surface for stretching out tower 1, is formed up big and down small
Back taper annular fair water cone 2.
Ensure that tower 1 is consistent with the tower 1 of traditional cooling tower, only consider influence of the cooling tower of fair water cone 2 to ventilation,
Only in the case of increase pyramidal structure, the ventilation of the cooling tower of the present embodiment is than conventional tower increase by 21.37%；Or just
On the premise of constantly inlet wind amount is constant, for the cooling tower of this programme relative to traditional cooling tower, the height H of the air inlet of its cooling tower can
To lower 25%, so as to reduce the lift of the center water distribution water pump of cooling tower, further, cooling tower is reduced
Production cost；The air inlet air-swirl situation of cooling tower can be improved after the fair water cone 2 of increase back taper annular, to air intake
The air fluidised form of mouth position has active influence；In addition, by calculating, after the fair water cone 2 of increase back taper annular, in cooling tower
The mean wind speed of filler opening position increases by 18.5% relative to traditional cooling tower, and corresponding cooling effectiveness also substantially increases.
Specifically, angle, θ is 25 degree in the present embodiment, certainly, angle, θ can be adjusted according to the actual needs,
Such as can also be 20 degree, 30 degree, 40 degree etc., still, when angle, θ is 25 degree, maximum is improved to the vortex of air inlet.
In addition, development length L and height H meets following relation：L≈1.1H.So fair water cone 2 coordinates air inlet to air intake
Air at mouthful is guided, and actually improves the vortex situation at cooling air inlet, and the fluidised form of air inlet position is played
Active influence.
With reference to figure 4, the tower 1 of the present embodiment is hyperbola tower 1, and the section of fair water cone 2 is linear pattern.Fair water cone 2
The junction of root and the outer surface of tower 1 ensures tightness when processing, and has occurred without hole, seam etc., accomplishes strict stuffy, energy
Enough avoid the savings of rainwater here, during actual use, the mechanism that rain cover is kept off the rain can be set between the outer rim of fair water cone 2 and tower 1
Further protected.
The surrounding of tower 1 is distributed in reference to 3,4 uniform intervals of reinforcer 3 of figure, each one end of reinforcer 3 is fixed in fair water cone
2, one end is fixed in the outer surface of tower 1.
The both ends of reinforcer 3 are connected to fair water cone 2 and tower 1, and fair water cone 2 is shifted part stress by reinforcer 3
To tower 1, reduce fair water cone 2 itself gravity and by external force the root of fair water cone 2 is influenceed, improve fair water cone 2 in reality
Stability when border uses.
Reinforcer 3 is uniformly arranged on the surrounding of tower 1, uniformly can share stress for fair water cone 2, ensure fair water cone
2 stability.It is arranged on as shown in figure 3,4 reinforcers 3 are adjacent into 90 degree around tower 1, shares stress for fair water cone 2, when
So in a further embodiment, reinforcer 3 can also be 3,5 or 6 etc. other suitable quantity, wherein reinforcer 3
Quantity can specifically be set according to the size and actual loading situation of tower 1 and fair water cone 2.
The reinforcer 3 for playing support fair water cone 2 is being specifically as follows the one or more of flexible connecting member or reinforcement.
That is reinforcer 3 can be entirely flexible connecting member, for example, hoist cable structure, or similar hoist cable structure；Can also be complete
Portion is the reinforcing rib structure of unitary rigid；Or can also be, while there are reinforcement and flexible connecting member.
Specifically, in the present embodiment, fair water cone 2 can be used as an entirety to carry out with tower 1 when Specific construction is built
Processing, i.e. fair water cone 2 belong to the structure of tower 1 of integral type equivalent to the part that hyperbola tower 1 stretches out.
Certainly in another specific embodiment of the present invention, fair water cone 2 is the structure set up on the basis of tower 1, also
It is fair water cone 2 and tower 1 is separated Split type structure, it can also reach the technique effect that integrative-structure is same above.
On the premise of influence of the consideration tower profile to ventilation, only increase fair water cone 2 without change cooling tower other
In the case of structure, cooling tower ventilation adds than the cooling tower of traditional structure；Accordingly, the feelings of normal intake are being maintained
Under condition, if being provided with fair water cone 2, cooling tower air intake open height can reduce, so as to reduce to center water distribution water pump
The requirement of lift, reduce the power consumption of water distribution water pump；And after increasing conical flow guiding cap, cooling air inlet can be improved
Locate vortex situation, have active influence to the fluidised form of air inlet position；In addition, after increase fair water cone 2, it is possible to increase filler position
Locate mean wind speed, the corresponding operating efficiency for improving cooling tower.
Second embodiment：
With reference to figure 5, in the second embodiment of the present invention, the root and the outer surface of tower 1 of fair water cone 2 are streamlined smooth
Transition, streamlined seamlessly transit can improve the stability that fair water cone 2 is connected in itself with the structure of tower 1.
3rd embodiment：
With reference to figure 6, in the third embodiment of the present invention, the cross section of fair water cone 2 is the arc being bent upwards, Neng Gougeng
The good fluidised form for agreeing with air inlet, improve and situation is vortexed at cooling air inlet.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, every utilization
The equivalent structure or equivalent flow conversion that description of the invention and accompanying drawing content are made, or directly or indirectly it is used in other correlations
Technical field, be included within the scope of the present invention.
