Product etc. is identical）, under conditions of cooling water flow be equal, the number of tower air capacity entered, will determine the cooling efficiency of water tower.Above-mentioned
Under constraint, as can the ventilation resistance of water tower is reduced, with regard to intake can be increased.Water tower ventilation resistance is by air intake vent resistance, rain
Area's resistance, filler resistance, water distribution and dehydrater resistance, wind turbine and resistance to flow output comprehensive function are formed.
Force ventilation cooling tower work when, air draft as caused by rotating wind turbine is drawn into tower, due into
The difference in tower path, due to environmental natural wind influence, due to arranged in tower inhomogeneities, also due in tower geometric space with
The interaction of air stream, air stream can generate turbulent flow in some spaces.Turbulent flow is a kind of three-dimensional of extremely complex unstable state
Flowing from physically, can regard turbulent flow as the flowing being formed by stacking by the vortex of various different scales, these vortexs
Size and rotary axis direction, speed and pressure be all random.Vortex constantly interacts, and increases air-flow in tower
Consumption, that is, the ventilation resistance of water tower is increased, reduce intake.
Compared with gravity-flow ventilation water tower, force ventilation tower is fewer by the adverse effect of environmental natural wind, but into the wind of tower
Speed is bigger, turbulent once being formed, has larger consumption.In the air inlet of force ventilation tower, horizontal deflector is set（Arc）,
The effect of being improved tower interior air-flow uniformity.

The object of the present invention is to provide a kind of turbulent flows reduced in tower, reduce the resistance of Ta Nei and air inlet, increase air inlet
Amount improves the air inlet guide method for mechanical ventilation water tower of the cooling efficiency of cooling tower.
A kind of air inlet guide method for mechanical ventilation water tower on the outside of the air inlet of force ventilation tower, is uniformly arranged vertical
In the deflector that guiding role is played to entering tower air stream of air inlet.
The air inlet guide method for mechanical ventilation water tower, the deflector and air inlet open height are contour, described
The thickness of deflector is meeting mechanical strength and rigidity needs select thin thickness, the spacing of adjacent baffle, for air inlet
The 1/4 of open height --- 1/1, the width of deflector, to enter the wind 1/3-the 2/3 of open height.
The air inlet guide method for mechanical ventilation water tower, the baffle surface have the noise elimination of absorbing sound and lowering noise function
Material or the baffle surface film mulching method, stick sound-absorbing material.
The air inlet guide method for mechanical ventilation water tower when deflector is installed, is drawn with pond center
Radially at an angle, the section of α is determined between-80 -+80 degree after carrying out theory analysis and experiment according to the design parameter of water tower
It is fixed.
The air inlet guide method for mechanical ventilation water tower, the deflector is using steel, fiberglass, plastics, aluminium
Alloy, concrete for making, the deflector are plate, arc or polygon.
Advantageous effect：
1. the present invention arranges vertical baffle in air inlet, makes into tower for the force ventilation counterflow cooling tower circumferentially entered the wind
Air stream, according to the most advantageous angle set, into water tower, is formed steady with centainly rotating under the induction of Prosthesis
Fixed air-flow.The present invention is suitable for the mechanical cooling tower circumferentially entered the wind.On the outside of water tower air inlet, vertical baffle is arranged,
Inducing action can be played to entering tower air stream, make to form the movement rail for being similar to typhoon formation and development in air inlet into tower air
Mark forms stable spinning updraft in cooling tower, so as to reduce space turbulent in tower, reduces air drag, increases
Add more than 3% air quantity.
2. the air inlet of the invention in force ventilation tower sets vertical deflector, breaches traditional idea.Our roots
According to theory analysis, test of many times has been done in laboratory, has found and proves, vertical baffle is installed in water tower air intake vent, it can be to entering
Tower air stream plays inducing action, makes to form the movement locus for being similar to typhoon formation and development in air inlet into tower air,
Stable spinning updraft is formed in cooling tower, so as to reduce the energy in space turbulent in tower and consumption, reduces sky
Atmidometer increases intake.
3. We conducted test of many times, find and prove, under the ideal conditions of no natural wind, the device can improve into
Air quantity 3%.Under the conditions of having natural wind, relative to traditional water tower, intake, which increases, is more than 3%, and natural wind speed is bigger, intake
Difference it is also bigger.
The present invention is suitable for the force ventilation counterflow cooling tower circumferentially entered the wind.China's refrigeration, air-conditioning system are a large amount of at present
Using the water tower of the pattern.Coming of new or the transformation of original water tower, can use the technology.
