Embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out lower premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementations
Example.
1 and Fig. 2, a kind of device for improving cooling tower thermal performance, including tower body 1 and be arranged at tower body 1 referring to the drawings
Blower fan 2 is provided with internal shower nozzle, the fixed air duct 6 in top of tower body 1, described air duct 6, the bottom of described shower nozzle is set
There is filler 7, described tower body 1 is internally provided with wide flabellum 3 and gas disturbing flow device 4, described tower body 1 and is additionally provided with horizontal stroke
Beam 8, described crossbeam 8 is located at the top of shower nozzle, and described gas disturbing flow device 4 is installed on crossbeam 8, described gas flow-disturbing
Device 4 is connected with crossbeam 8, and described wide beam inducer 10 is located at the bottom of maintenance wide beam 9, described wide beam outlet water conservancy diversion
Device 12 is located at the top of maintenance wide beam 9, and described symmetrical arc homogenizing plate 13 is located at the top of wide beam exducer 12.
Implement said apparatus, be made up of high-efficiency axial-flow blower 1, gas disturbing flow device 4 and upper spray shower nozzle 5, in cooling tower
Installation transformation is carried out, air volume cooling tower is added during implementation and windage in tower is reduced, to improve the heat exchange property of cooling tower, cooling
Tower blower fan 2 is arranged on tower inner top crossbeam 8, and the suction side of blower fan 2 in beam column both sides due to that when gas streams crossbeam 8, can separate
It is vortexed with being formed on beam top, not only increases additional drag, and the capacity for work of the impeller of blower fan 2 can be had a strong impact on, makes air quantity
Reduce, noise increase, waste of resource, the final cooling effect for having a strong impact on tower again, it is necessary to improve the surrounding of crossbeam 8 smooth.To keep away
Exempt from the generation of this phenomenon, install disturbing flow device 4 additional on crossbeam 8, smoothness can be transformed, can make to move after gas burble point, on crossbeam 8
Fang Yin is limited by dimensional space, and described gas by-pass means 4 are, according to the physical dimension of crossbeam in tower 8 and space customization, to protect
The airflow homogeneity in tower is demonstrate,proved, without around flow phenomenon generation.
It is preferred that, described wide flabellum 3 is installed on blower fan, and described wide flabellum 3 is installed on the wheel hub of blower fan 2,
Described wide flabellum 3 is connected with blower fan 2, and described wide flabellum 3 is to be cut into type using pultrusion, it is ensured that the stabilization of its structure
Property.
It should be noted that pultrusion cuts wide blade under the operating mode of underload, pultrusion cuts wide blade and plate leaf
The performance of piece blower fan is very nearly the same why in the past, many in fan design this also illustrates to reduce the original of cost using plate blade
Cause.And under high load capacity operating mode, the performance of plate blade drastically declines, and pultrusion cuts wide blade due to good pneumatic property
Can, overall objective is increased substantially on the contrary, to find out its cause, good airfoil surface VELOCITY DISTRIBUTION causes flowing matching more adduction
Reason, so as to improve overall performance.From the point of view of local flow characteristic, pultrusion cuts the air-flow matching capacity of wide blade blower fan more
By force, aerodynamic loss is smaller, therefore, and its stable operation range is also wider.And the blower fan of traditional cooling tower, on-line velocity maximum fan
End, width is minimum, and utilization ratio is low, and a kind of new blower fan of cooling tower 2 of this programme, in end, also there is very big width,
Efficiency is more much higher than traditional, it is ensured that the acting area Wind Volume of the new flabellum of fan of equal-wattage same diameter is big；
It is preferred that, described shower nozzle water distribution manner is that the described upper model of spray shower nozzle 5 is inner-rotary type using upper spray shower nozzle 5
Shower nozzle.
The technology application of upper spray water distribution manner, it is ensured that when increasing substantially the gentle exchange area of water and extending exchange
Between, the height of original tower packing is effectively reduced, reduces windage of the filler to tower interior air-flow.Its specific advantage is to extend gas
Hydrothermal exchange time, the upper top of spray shower nozzle 5 add 2 meters of rain belts, effectively increase the specific surface area, water distribution efficiency high, cloth of water
Water is uniform, do not see plug is easy to maintenance.
In other words, upper spray technique is exactly that water distribution system is highly adjusted, and increases spraying altitude, reduces unit
The number of water droplet in volume, while reducing the resistance of water droplet, plays more preferable cooling-down effect.
The present invention is implemented：As shown in Figures 1 and 2, cooling tower is increased by changing high-efficiency axial-flow blower
Cooling air quantity, is introduced cold air outside tower in tower by the draft effect of Wind Volume, logical in the recirculated water introduced with water distribution pipe
The time for the preliminary heat exchange of high-order rain belt increase that spray shower nozzle is produced is spent, secondary heat exchange is carried out falling after rise to filler, to carry
The efficiency of high heat exchange.Saturated steam after heat exchange can run into the crossbeam 8 in tower in uphill process, be installed additional on crossbeam 8
Gas disturbing flow device 4, saturated steam is then passed through wide beam exducer 12 into wide beam inducer 10, eventually passes through pair
Claim arc homogenizing plate 13, install the airflow homogeneity in the guarantee tower of gas disturbing flow device 4 additional, without being produced around flow phenomenon, be to reduce
System produces vortex on beam and increases the flow resistance of wind, so as to reduce windage inside tower, it is ensured that damp-heat air is excluded outside tower, this
Sample makes the cooling effect of cooling tower more preferably, and cooling tower thermal performance is improved.
In summary, a kind of device for improving cooling tower thermal performance that the present invention is provided, is used inside cooling tower
New pultrusion cuts wide flabellum 3 to change the blade of conventional fan 2, the acting area to increase flabellum；In cooling tower on crossbeam 8
The gas by-pass means 4 customized according to the dimensional space of crossbeam 8 are installed, to improve windage and the balance of wind-force in tower；Cooling
Tower water distribution system uses the water distribution manner of internal rotation type upwards spraying nozzle 5, can increase the heat exchanger time of aqueous vapor, replaces part cooling tower and fills out
The heat exchange of material 7, is effectively reduced the windage of 7 height reduction filler of filler 7.There is advantages below compared with prior art：1) it is identical
The blower fan of diameter equal-wattage, can increase air quantity；2) windage inside cooling tower is reduced；3) spray technique can extend aqueous vapor heat in tower on
Swap time, it is effectively reduced packed height.
