Description
Technical field
The present invention relates to cooling towers, are more specifically widely used in naturally logical in the energy, petrochemical industry and field of metallurgy
Cooling Tower air intake guide device.
Background technique
Cooling stack is used widely in the industries such as the energy, petrochemical industry and metallurgy, is will carry waste heat cold
But water carries out heat exchange in Ta Nei and humid air, so that waste heat is transferred to humid air and spills into atmosphere；Cooling stack is general
It using hyperbola tower body, is supported in bottom by herringbone column, air inlet is between adjacent herringbone column, and facility mainly has and matches in tower
Water system, filler bracket, packing, spraying and splashing facility, dehydrater and collecting-tank, drip water plate (high-order tower), water receiving tank are (high-order
Tower) etc..
The draft that cooling stack relies primarily on the formation of cooling tower inner air and outer air density contrast is acted on cooling air certainly
Through in cooling tower air inlet sucking tower, cooling air is followed by rain belt (conventional tower) or through water collector inclined plate channel outside tower
Cooling tower is flowed out through cooling tower upper area behind small rain belt (high-order tower), packing area, spraying zone, receipts pool, is discharged into big
In gas.Cooling air contacts through rain belt, packing area, spraying zone with high-temperature cooling water cold through mass-and heat-transfer heat exchange absorption high temperature
But hydro-thermal amount reduces cooling water temperature.
General drenching area is greater than 9000 square meters and is large cooling column, greater than 12000 square meters is ultra-large type cooling tower, for
Large-scale and ultra-large type cooling stack, due to drenching area super large, air inlet open height is high, in tower very along radial direction air inlet
Unevenly；For conventional chilling tower, longitudinal vortex that air inlet upper limb generates causes close tower wall, and nearby air velocity is lower, and
It is lower closer to tower center air flow velocity due to the drag effect of rain belt；Water cooling tower is received for a high position, due to eliminating heavy rain
Area, without the drag effect of rain belt, the penetration power of cooling tower bottom air inlet is stronger, closer to tower immediate vicinity air velocity
It is higher, and because of longitudinal vortex reason that cooling tower air inlet upper limb generates, close to tower wall, nearby air velocity is low；Cooling tower is along diameter
Cooling tower cooling capacity is unevenly reduced to air inlet, Fig. 6 show conventional tower and high-order tower ambient wind velocity and outlet water temperature
Relation curve, it is very big that Fig. 6 relation curve shows that environment crosswind influences cooling tower outlet water temperature.Either conventional chilling tower, also
It is high-order receipts water cooling tower, the influence to environment crosswind is very sensitive, but high-order tower is more sensitive, when crosswind destroys calm
The symmetry in air's velocity field, pressure field, temperature field etc., crosswind cause cooling tower air inlet radially more uneven.Due to side
Wind action, longitudinal vortex that cooling tower air inlet upper limb generates increases, as shown in fig. 7, therefore weakening the effective of cooling tower
Incoming air area, reduces the intake of cooling tower and the efficiency of cooling tower, and crosswind is bigger to the high-order influence for receiving water cooling tower.It grinds
Study carefully and show ambient wind velocity up to 5m/s, conventional chilling tower outlet water temperature is increased up to 2.5 DEG C, and high-order tower outlet water temperature is increased up to 3.0
DEG C, conventional tower and high-order tower ambient wind velocity and outlet water temperature relation curve are as shown in Figure 4.As it can be seen that cooling tower air inlet is uneven
Seriously reduce the efficiency of cooling tower.
In order to reduce the inhomogeneities of cooling tower air inlet, existing the relevant technologies are built on cooling tower air inlet surrounding ground
Several air-guiding walls with certain angle are made, so that cooling tower air inlet is generated eddy flow in tower, increases the uniformity and intake of air inlet,
The influence of environment crosswind is reduced, which, which enters the wind and reduce ambient side wind effect for the cooling tower of no cross windbreak, one
Fixed effect, but the overwhelming majority is installing cross windbreak additional with cooling tower at present, has filled the cold of cross windbreak for having
But the effect of tower, the air-guiding wall greatly reduces, and loses Practical significance.
Summary of the invention
The present invention is to provide a kind of cooling stack air inlet to avoid above-mentioned existing deficiencies in the technology
Guiding device, to obtain the uniformity that improvement cooling stack, especially a gravity-flow ventilation high position receive water cooling tower air inlet,
Changing environment crosswind adverse effect be it is beneficial, improve the cooling effect of cooling tower.
The present invention adopts the following technical scheme that in order to solve the technical problem
Cooling stack air intake guide device of the present invention, the cooling tower has hyperboloid tower body, in the hyperbolic
The bottom of transmission tower body is circumferentially arranged herringbone column and forms tower seat, and each air inlet is between adjacent herringbone column；Its design feature
It is: in each air inlet, between two adjacent herringbone columns, at least one layer of guide vane is set, the guide vane will
Air inlet is being divided at least two layers of air intake vent along short transverse.
The design feature of cooling stack air intake guide device of the present invention is lain also in: the guide vane is at both ends point
The herringbone column for not being fixed at corresponding side using connector is upper or is fixed on tower seat attachment；The tower seat attachment is
Refer to: being corresponded by herringbone column position and each herringbone column and be set side by side with steelframe, the guide vane is sharp respectively at both ends
It is fixed at connector on the steelframe of corresponding side.
The design feature of cooling stack air intake guide device of the present invention is lain also in: the guide vane is in inlet air one
Side has an air outlet angle of setting in level, in outlet air side, the air outlet angle refer to guide vane in outlet air side with
The angle of horizontal plane, air outlet angle α are greater than zero.
The design feature of cooling stack air intake guide device of the present invention is lain also in: for multilayer guide vane, respectively
Air outlet angle α of the layer guide vane in its outlet air side is not identical；The not identical outlet air angle for referring to top layer guide vane
Degree is maximum, and the air outlet angle of bottom guide vane is minimum, and each layer guide vane air outlet angle from top layer to bottom is gradually
Reduce, forms the stream that raises up in outlet air side.
The design feature of cooling stack air intake guide device of the present invention is lain also in: in entering for each guide vane
Wind side and outlet air side are arc transition.
Compared with the prior art, the invention has the advantages that:
Guide vane is arranged in the air inlet of cooling stack in the present invention, by reasonably configuring guide vane
The air outlet angle of the number of plies, interlamellar spacing and each guide vane can effectively eliminate the longitudinal direction of cooling tower air inlet upper limb generation
Vortex increases the effective incoming air area of cooling tower, enters the wind cooling tower bottom radially and tends to uniformly, guidance crosswind is by " expectation "
Path enters in cooling tower, and changing harmful crosswind is benefit, effectively improves the cooling effect of cooling tower.
