Abstract
The utility model relates to an aerodynamic vortex device of a cooling tower in a power station, which is arranged in the air inlet position of the cooling tower. The vortex device comprises a plurality of guide plates; the guide plates are arranged around the air inlet of the cooling tower and close to a herringbone column of the air inlet of the cooling tower; a tension bracing piece is mounted between every two adjacent guide plates; and adjacent tension bracing pieces are mutually connected. In the case that the building structure of the internal structure of the cooling tower in the power station is not changed, the guide plates are integrated into an integral aerodynamic vortex device through the tension bracing pieces which are mutually connected, outside air flows into the cooling tower through channels sandwiched between adjacent guide plates, to form certain vortex in the tower, vortex air and sprinkled water are more sufficiently mixed, heat transfer and mass transfer of gas phase and liquid phase are enhanced, the cooling efficiency of the cooling tower is improved, simultaneously vortex airflow field can extend to the upper part of the cooling tower, to ensure that the fullness degree and the rigidity of discharged airflow are improved, and the blow resistance capability is enhanced, therefore, the water loss of the cooling tower can be reduced.
Description
Technical field
The utility model relates to a kind of Cooling Tower of Power Station, refers to a kind of air force vortex device that is installed in Cooling Tower of Power Station air inlet position especially.
Background technology
In the existing Cooling Tower of Power Station, the improvement of strengthening the heat transfer technology of recirculated cooling water and air mainly concentrates in packing layer structure, material and the tower blocks the aspect, though someone proposes the outer import fairing of a kind of tower, but complex structure, the import wind resistance is bigger, air-flow mixes and heat exchange and not obvious in the tower for improving, and is not applied.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of novel cooling tower peripheral hardware fairing, thereby overcomes the defective of existing fairing complex structure, heat exchange poor effect.
For solving the problems of the technologies described above, the utility model provides a kind of Cooling Tower of Power Station air force vortex device, be arranged at cooling tower air inlet position, described vortex device comprises plural piece guide plate, and described guide plate is around the air inlet setting of described cooling tower and be close to the herringbone column of cooling tower air inlet; Set up a stay bolt spare between the two adjacent guide plates, and interconnected between the described adjacent stay bolt spare.
Under the situation that does not change Cooling Tower of Power Station building structure and internal structure, by interconnective stay bolt spare each guide plate is integrated into holistic air-swirl device, the passage that extraneous air is established formation by folder between each adjacent guide plate enters cooling tower, in tower, form certain eddy current, rotational flow air mixes more abundant with the water that drenches down, strengthened the heat and mass transfer of gas-liquid two-phase, improve the cooling tower cooling effectiveness, eddy flow gas field can be extended to cooling tower top simultaneously, make exhaust jet stream degree of filling and rigidity reinforcement on the tower, anti-environment wind ability is strengthened, thereby can reduce the cooling tower dehydration.
Further improvement of the utility model is that the angle of described guide plate and herringbone column's tower root place circumference contact point tangent line is 15 ° ~ 60 °, through a large amount of air rectification effect the bests in this number of degrees scope that experimental results show that.
Further improvement of the utility model is that described stay bolt spare can be tabular, is set up in the upper end of described guide plate; Also can be shaft-like, comprise a cross bar and a montant this moment, and described cross bar is set up in the upper end of described guide plate, and described montant is supported in the side of described guide plate.
Further improvement of the utility model is, described guide plate be shaped as parallelogram, trapezoidal, pentagon, rectangle or arc of curvature quadrangle.
Further improvement of the utility model is that the material of described guide plate is plank, concrete walls, organic composite material or metallic plate; The material of described stay bolt spare is wooden, metal, concrete or organic composite material.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult shown in Figure 1, Cooling Tower of Power Station 10 comprises the tower body 11 of a hyperboloid tubular, be equipped with a circle herringbone column 12 in the bottom of tower body 11 (also being referred to as the tower root), be used to support whole tower body 11, and herringbone column 12 spaces and 12 formation of each adjacent herringbone column own have constituted the air inlet of this position formation cooling tower 10, and air force vortex device of the present utility model promptly is arranged at this air inlet position.
Cooperate shown in Figure 2ly, air force vortex device of the present utility model mainly is made up of guide plate 20 and stay bolt spare 30 two parts; Wherein:
Set up a stay bolt spare 30 between the two adjacent guide plates, and interconnect between the adjacent stay bolt spare 30, thereby make all guide plates 20 form a circle, guarantee that this air force vortex device erects the stability and security of work for a long time by the overall structure that stay bolt spare 30 is linked to be; Stay bolt spare 30 can be a platy structure as shown in Figure 2, it is set up in the upper end of adjacent guide plate 20, it also can be rod shaped structure as shown in Figure 3, this moment is integrally-built stable in order to guarantee, stay bolt spare 30 comprises a cross bar 31 and a montant 32, cross bar 31 be set up in guide plate 20 between any position, montant 32 is supported in the side of described guide plate 20.
This air force vortex device is in adjacent suitable shape, form suitable air duct between the size and the guide plate 20 of arranging, under the spontaneous draft power effect of cooling tower 10, air in the environment is forced to enter from air duct, guide plate 20 makes air-flow become necessarily tangentially to enter along cooling tower 10 inwalls, thereby make the living rotation to a certain degree of air miscarriage that enters, rotary air stream contacts with water generates under the spray in uphill process and mixes, the Heat transfer of gas-liquid two-phase mass transfer takes place, make cooling water temperature air themperature rising in the tower, reached the reinforcement that biphase gas and liquid flow mixes.Its effect is embodied in:
The one, improved cooling effectiveness, coolant water temperature descends about 1 ℃-2 ℃, improves the about 0.1%-0.3% of generating efficiency;
The 2nd, the cooling blast rotation is risen its degree of filling and rigidity in tower is strengthened, and has reduced cooling blast to airborne band water.In addition, the effect of blocking of guide plate 20 gets the hang of the cooling air and affected by environmently greatly weakens, thereby reduces the fluctuation of cooling tower cooling capacity.
