Description
Technical field
The utility model belongs to industrial cooling stack technical field, and a kind of more particularly to drag reduction synergy is led to naturally
Air drying type cooling tower air inlet inclined strut structure.
Background technology
The inclined strut of large-scale cooling stack largely uses reinforced concrete cast-in-situ structure, also has minority to use steel
Reinforced concrete precast construction, steel construction or concrete filled steel tube.
For reduce cooling tower air inlet air drag, air inlet inclined strut should use the less cross section of gas-flow resistance and
Pattern.Wet-style natural-ventilation cooling tower inclined strut generally use cylinder.Dry type cooling stack is due to its air intake open height
Larger, to meet inclined strut member structure stability and convenient construction, inclined strut cross section uses rectangular cross section more.
It is generally believed that rectangular column air drag compared with circular or long round section is big many.In design wind speed condition
Under, the reynolds number Re of cooling tower inclined strut is about 2 × 105~3.5 × 105Left and right, approaching or at " resistance coefficient Dou Jiang areas ".
In the case of projected area identical windward, the resistance coefficient of square-section pillar is forward and backward semicircle leg resistance coefficient
Close to more than 2 times.
In view of the design of industrial cooling stack, construction present situation, it is necessary to propose a kind of Novel cooling tower inclined strut
Structure, the cooling tower for generally using rectangular cross section inclined strut is undergone technological transformation, reduce the air drag of pillar, improved cold
But the air intake efficiency of the whole tower of tower.The new existing cooling tower structure stress system influence of corbeling reply is small, while is easy to construct.
Utility model content
A kind of leading to naturally for drag reduction synergy is provided to solve deficiency, the utility model existing for existing pin designs
Air drying type cooling tower air inlet inclined strut structure；The inclined strut structure can not change the design of existing square-section inclined strut and
On the premise of construction method, scheme, by setting up additional pneumatic baffle structure, reduce the air resistance of air inlet inclined strut
Power, so as to improve the air intake efficiency of the whole tower of cooling tower.
To achieve the above object, the utility model takes following technical solution：
A kind of gravity-flow ventilation dry cooling tower air inlet inclined strut structure of drag reduction synergy, including cross section is rectangular configuration
Cooling tower inclined strut, cooling tower inclined strut windward side and leeward side are provided with pneumatic baffle；Pneumatically baffle is transversal
Face is arc structure, and two arc structures splice in the front and rear sides of rectangular configuration respectively.
Described cooling tower inclined strut is the reinforced concrete structure or rectangular steel tube with concrete infilled of rectangular cross section.
Described pneumatic baffle is the metal with support frame or nonmetallic arc-shaped stressed-skin construction, the support of arc-shaped
Skeleton is connected with the rectangular section column of cooling tower inclined strut, and covering is arranged on support frame.
Described pneumatic baffle is solid made of lightweight material or hollow circular arc body structure, outer surface metal,
Nonmetallic thin skin.
Described lightweight material is foamed plastics.
Using anchor ear, bolt, welding or adhesive means connection between described pneumatic baffle and cooling tower inclined strut.
It is as follows relative to traditional structure system, the major advantage of the new inclined strut structure：
Cooling tower inclined strut windward side and leeward side of the present utility model are provided with the pneumatic baffle of arc structure, should
Inclined strut structure can be on the premise of existing square-section inclined strut design and construction method, scheme not be changed, by setting up
Additional pneumatic baffle structure, reduce the air drag of air inlet inclined strut, so as to improve the air intake efficiency of the whole tower of cooling tower.
This is simple in construction, does not change square-section inclined strut design method, does not change square-section inclined strut construction method, and rectangle is cut
Face inclined strut stress can be ignored, due to using follow-up secondary construction, can be not only used for newly-built cooling tower, it can also be used to existing old tower
Transformation for increasing productiion capacity；And pneumatic baffle light weight, low cost.
Further, the pneumatic baffle of windward side, the pneumatic baffle of leeward side are the metal with support frame or nonmetallic circle
Arcuation light-skinned structure, or the solid or hollow circular arc body structure for lightweight materials such as foams.In original square-section inclined strut
Increase pneumatic baffle in structure, the effective air drag for reducing air inlet inclined strut, so as to improve entering for the whole tower of cooling tower
Wind efficiency.
Further, the pneumatic baffle prepared using light material, only aerodynamics Drag reduction devices, are not structures
Body, it is not involved in, does not change the stress system of cooling tower inclined strut.
