Abstract
Disclosed is an even air intake guiding device for a natural ventilation cooling tower, which is used for improving the air intake volume, air intake evenness of the cooling tower and lowering the outlet water temperature of the cooling tower; the utility model adopts the technical scheme that the rain zone of the cooling tower is provided with cross baffles, and a clearance is arranged between two baffles with the same diameter; the outer circumference of the bottom of the cooling tower is provided additionally with a plurality of guide plates which are straight or curved rectangular plates, and are evenly arranged along the outer circumference of the bottom of the cooling tower; and the guide plates are tangent to the outer circumference of the cooling tower or have an inclination angle with the tangent direction. By adopting the structure, an air intake channel is formed between the adjacent baffles and the guide plates, leading the crossing natural wind to be commutated to the favorable wind and to be evenly guided into the cooling tower, so the problems that the air intake unevenness and gas water contact deterioration in the presence of the crossing wind are solved, and the outlet water temperature of the cooling tower is lowered.
Description
Technical field
The utility model relates to a kind of cooling tower uniform air intake diversion technology, belongs to technical field of power generation.
Background technology
The cooling tower that present thermal power plant uses is hyperbolic-type, gravity-flow ventilation around the bottom.Its operation principle is: recirculated cooling water sprays downwards by water distribution system, become membranaceous along packing layer then and flow downward, air upwards flows from bottom inlet by density contrast, the abundant contact heat-exchanging of air and recirculated water, make circulating water temperature reduce, thereby finish the heat and mass transfer process.Actual motion and numerical simulation show: during no natural wind, the cooling tower air intake is even, gas, water full contact in the tower, and the cooling effect of recirculated water is best.When beam wind, because air flows, there is the air intake dead band in the packing area near the air inlet of windward side, and beam wind has also destroyed the uniformity of air intake in addition, and these all make gas in the cooling tower, water contact worsen, and the cooling effect of recirculated water reduces.Beam wind is big more, and this influence is bigger.
Summary of the invention
The utility model is used to provide a kind of and can significantly improves intake, the air intake uniformity of cooling tower and use the cooling stack uniform air intake guiding device that the tower water temperature reduces.
The technical scheme that addresses the above problem is:
A kind of cooling stack uniform air intake guiding device is provided with 4 block length square spacer plate, and becomes cross configuration in the cooling tower rain belt, an end of dividing plate flushes with cooling tower bottom outer circumferential edges, leaves spacing between two dividing plates on the same diameter.
Above-mentioned cooling stack uniform air intake guiding device, around the cylindrical of cooling tower bottom, set up a plurality of deflectors, deflector is evenly placed along cooling tower bottom circumference is outside for facing directly or the curved surface rectangular slab, and deflector is tangent with the cooling tower excircle or become an inclination angle with tangential direction.
Above-mentioned cooling stack uniform air intake guiding device, the spacing between two dividing plates on the described same diameter is 1/3 diameter.
Above-mentioned cooling stack uniform air intake guiding device, perforate on described dividing plate or the deflector, the aperture is 5～20mm, the perforate gross area accounts for the gross area 10%～50% of plate.
The utility model forms air intake passage between adjacent separator and deflector, can be favourable wind with horizontal natural wind rectification, and evenly import cooling tower, solved the problem of cooling tower air intake inequality when beam wind is arranged, air water contact deterioration, greatly reduce out the tower water temperature.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation after the utility model is set up deflector.
Mark is as follows among the figure: cooling tower 1; Dividing plate 2; Deflector 3.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a kind of embodiment that installs dividing plate in cooling tower 1 rain belt additional, and Fig. 2 embodiment has installed dividing plate 2 additional in cooling tower 1 rain belt, and installs deflector 3 additional along tower week.The utility model can only install dividing plate 2 additional in reality is implemented, also can only install deflector 3 additional, perhaps dividing plate 2 and deflector 3 is made up and installs additional, and above-mentioned three kinds of structures all should belong to protection domain of the present utility model.
Fig. 1 is the three-dimensional structure schematic diagram that cooling tower of the present utility model 1 rain belt installs dividing plate 2 additional.This dividing plate 2 becomes cross layout in cooling tower 1 rain belt.Because cooling tower 1 bottom is the rain belt, cooling tower 1 central authorities are subjected to a little less than the influence of natural wind, and need bigger air quantity, so cooling tower 1 central authorities can not arrange dividing plate 2, do not arrange that the scope of dividing plate 2 is about 1/3 of cooling tower 1 base diameter.Dividing plate 2 can be an atresia, also can be porose, and the aperture is 5～20mm, and the perforate gross area accounts for the gross area 10%～50% of plate.
Fig. 2 is dividing plate 2 and deflector 3 compound modes.On Fig. 1 architecture basics, 1 circumference air inlet place installs deflector 3 additional along cooling tower, and each outside deflector 3 is tangent with cooling tower 1 bottom circumference or become 0～miter angle with tangential direction.Form air intake passage between the adjacent baffle 3, when beam wind, wind is rectified into wind direction and the homogenising that is suitable for cooling tower 1 work by air intake passage.Deflector 3 can be an atresia equally as required, also can be porose, and the aperture is 5～20mm, and the perforate gross area accounts for the gross area 10%～50% of plate.
Outside above-mentioned two kinds of structures, dividing plate also can only be installed additional in the cooling tower bottom according to actual needs in power plant, or only installs deflector additional around the cylindrical of cooling tower bottom, all can improve the cooling tower cooling effect.Applied fluid mechanics software (CFD) numerical simulation shows, the guiding device effect of dividing plate and deflector combination is best.
