Background technology:
Cooling tower be utilize evaporation and convection current cooling principle make hot water cooling with reduce circulating water temperature device, hot water with
Carrying out the heat and mass transfer process of complexity between air, total effect is water evaporates, absorbs the latent heat of vaporization, makes water temperature reduce.
Circulating water temperature directly affects the economy of Thermal generation unit, and under design condition, circulating water temperature often reduces by 1 DEG C can be made to send out
Group of motors heat consumption reduces by 0.3%～0.5%, and unit generation coal consumption declines 1.3g/ (kw h).Recirculated water sprays downwards from tower top
Drenching, carry out heat exchange by filler and air, flow up after air heats in tower, tower outer air enters in tower from surrounding,
Formation air flows.When air enters cooling tower, in cooling tower, around lower limb, about about 5 meters range contents are easily generated whirlpool
Whirlpool, in causing this region, air velocity reduces, and affects the recirculated water heat radiation in this region.
Utility model content:
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, it is provided that one can reduce under cooling tower
The air ducting of edge air intake whirlpool, this device can effectively reduce cooling tower lower limb air intake whirlpool, increase this region to
Upper wind speed.
In order to achieve the above object, this utility model adopts the following technical scheme that and realizes:
A kind of air ducting that can reduce cooling tower lower limb air intake whirlpool, including being arranged on cooling tower lower limb air intake
The fixed support at place, and the wind deflector that one end is flexibly connected with fixed support, wherein, the other end of wind deflector passes through support bar
It is connected with fixed support.
This utility model is further improved by, and one end of wind deflector is flexibly connected with fixed support by hinge.
This utility model is further improved by, and fixed support is arranged on cooling tower lower limb by some installation buckles
At air intake.
This utility model is further improved by, and fixed support, support bar and wind deflector are combined into and cooling tower outer wall
Tangent line is the annular air ducting of 60 ° of angles.
This utility model is further improved by, and fixed support is the rectangular frame of 2000 × 1000mm, uses Φ
10mm steel bar butt welding forms.
This utility model is further improved by, a length of 1000mm of support bar, use Φ 10mm reinforcement fabrication and
Become.
This utility model is further improved by, and wind deflector specification is 2000 × 1000 × 5mm rectangular faceplate, uses
Fiberglass is made.
This utility model is further improved by, and in the circumference of cooling tower, every spacing 4mm is disposed with an air ducting.
Compared with prior art, this utility model has the advantages that
This utility model is arranged under cooling tower below eaves, forms the ring with 60 ° of angles of tangent to periphery after propping up wind deflector
Shape stator, along the circumferential direction spiral when air enters eaves under cooling tower, thus effectively stop whirlpool in cooling tower lower limb
Produce, increase air flows upwards speed, strengthen recirculated water heat radiation, and the impact that cooling tower is dispelled the heat by crosswind can be alleviated,
After installing this utility model device, cooling-tower circulating water temperature can reduce about 0.5 DEG C.In winter, wind deflector can be put by northern area
Fall, Radix Saposhnikoviae, antifreeze effect can be played, prevent cooling tower from freezing.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 this utility model mounting arrangements schematic diagram；
Fig. 3 cooling tower intake velocity scattergram.
Detailed description of the invention:
Below in conjunction with the accompanying drawings this utility model is described in further detail:
With reference to Fig. 1, this utility model is a kind of air ducting that can reduce cooling tower lower limb air intake whirlpool, including solid
Fixed rack 1, support bar 2 and wind deflector 3, wherein, 1 fixation of fixed support, support bar 2 plays a supportive role, wind deflector 3 one
While be fixed on fixed support 1 with hinge 4, prop up with support bar 2.This utility model is arranged on below cooling tower lower limb one
In week, support bar 2 forms the annular stator of circumferentially tangent line angle 60 ° after propping up wind deflector 3, when air enters cooling tower lower limb
Circumferentially spiral, thus in effectively stoping cooling tower lower limb, whirlpool produces, and increases air flows upwards speed, strengthens following
Ring water-cooled.
Described device fixed support 1 is formed by Φ 10mm steel bar butt welding, and support bar 2 is formed by Φ 10mm reinforcement fabrication, leads
Aerofoil 3 material is fiberglass, specification 2000 × 1000 × 5mm；
With reference to Fig. 2, described device is arranged on below the cooling tower lower limb 7 of cooling tower cylinder 6, by spacing is circumferentially
4mm arranges, support bar 2 forms the annular stator of circumferentially 60 ° of angles of tangent line after propping up wind deflector 3.
With reference to Fig. 3, this utility model is according to the nonunf ormity of thermal power plant's large cooling column air's velocity field, i.e. air
When entering cooling tower, in cooling tower, around lower limb, about about 5 meters range contents are easily generated whirlpool, cause air in this region
