Typically in 9-12 degree or so, angle of flare is big at scattered angle, and it is inclined that the air-flow occurred by natural wind effect is easily formed in tower exit
Turn, in the presence of natural wind, cooling tower outlet windward side tower interior air-flow can produce separation, and the outer air of tower invades tower in Disengagement zone
It is interior, draft is influenceed, also thus influences cooling effectiveness, to reduce the influence that natural wind exports to cooling tower, some cooling towers will go out
Mouth is designed to closing in type, but the experiment of research institution and the actual measurement of entity tower are all shown, the cooling tower internal drag of this closing in type
Larger, cooling effectiveness is not so good as the cooling tower with angle of flare.
Utility model content：
The purpose of this utility model is to provide a kind of cooling tower that reduces and exports separation degree caused by windward side tower interior air-flow,
Generally increase entering tower air capacity, improve heat exchange operating mode in tower, improve the technology of efficiency of cooling tower, it is found through experiments that simultaneously
Checking, guiding device is installed in tower top, realizing reduces natural wind adverse effect, generally improves having for cooling tower cooling effectiveness
Imitate device.
Above-mentioned purpose is realized by following technical scheme：
A kind of cooling tower tower top guiding device, its composition include：Cooling tower, water conservancy diversion dress is installed on described cooling tower
Put, described guiding device includes guide ring, and the top arranged concentric of described guide ring and described cooling tower, described leads
The diameter for flowing ring is more than the diameter on described cooling tower top, and a circle deflector is provided with inside described guide ring, described
One end of deflector is fixedly connected with described guide ring, and the barrel of the other end of described deflector and described cooling tower is consolidated
Fixed connection.
Described cooling tower tower top guiding device, described guide ring are highly the top end diameter of described cooling tower
0.05-0.25 times, the upper height of described guide ring is higher than the height on the top of described cooling tower, described guide ring
Inwall be smooth circular arc, the outer wall of described guide ring is corrugation plate shape or smooth circular arc.
Described cooling tower tower top guiding device, described deflector and level are in 45-90 degree angle, described deflector and
Described cooling tower radical is in 45-75 degree angle, and the quantity of described deflector is 6-40 pieces.
Beneficial effect：
1. provided by the utility model is a kind of cooling tower tower top guiding device, advantageously reduces natural wind and cooling tower is gone out
The adverse effect of mouth, also improve the ventilation condition in tower, the total ventilation increase 3-8% of cooling tower.
The cooling effectiveness of traditional cooling tower can improve 5% or so typically between 35-65% after setting up guide ring, into
Series-produced machine power cooling tower, there is high cost performance, also can be easily to the cooling stack of tall and big body
Used in design.
The utility model is advantageous to energy-saving and emission-reduction and environmental protection.
The outer wall of the utility model guide ring is arranged to corrugated type, can increase resistance, reduces the adverse effect of natural wind.
Guide ring and deflector of the present utility model select fiberglass, pvc plastics, aluminium alloy, steel construction or reinforced concrete
Soil is main material.
