Description
Technical field
The utility model relates to cooling tower technical field more particularly to a kind of wet cooling towers with falcate filler.
Background technique
Information disclosed in the utility model background technique is merely intended to increase the reason to the general background of the utility model
Solution, without being necessarily considered as recognizing or implying that information composition has become persons skilled in the art institute public affairs in any form
The prior art known.
Natural draft counter-flow wet cooling tower is widely used in China's power domain gene, with basic principle are as follows: hot water by
Pipeline is made a gift to someone hot water dispensing system by vertical tube (vertical shaft), and then by splashing device, water is spread across on filler；After filler at
Rain shape falls people's reservoir, and water after cooling, which is taken away, to be reused, tower bottom be air inlet, air from air inlet into people's tower body,
Rain belt and hot water under filler flow into opposite direction and flow through filler (therefore claiming reverse-flow), recycle air by water collection device
In water droplet after the street Zai Congta outlet discharge, the outer cold air of tower scatters and disappears into after people's cooling tower, absorbing to be evaporated by hot water and be contacted
Heat, temperature increase, and humidity becomes larger, and density becomes smaller, since the inside and outside atmospheric density difference of tower generates pressure difference inside and outside air inlet,
Cause the outer air-source source of tower constantly to flow into tower and provides power, as gravity-flow ventilation without ventilating machinary.
In the process of running, air enters cooling tower, recirculated water from bottom air inlet mouth to natural draft counter-flow wet cooling tower
It is fallen from cooling tower water distributing area, air and recirculated water are in water distributing area, packing area and rain belt completion heat and mass transfer process.Due to cooling
Tower self structure, under calm operating condition, air mass flow is constantly reduced along cooling tower radical, causes cooling tower performance radially continuous
It reduces, forms heat transfer deterioration area inside cooling tower.Patent document CN 102607324A discloses " the one of wet cooling tower filler
Kind of novel arrangement mode " is that a kind of diametrical direction along wet cooling tower takes the non-mode being arranged at an equal altitude of filler, in wet type
The center filler of cooling tower is most thin, and the peripheral rim portion packed height of tower is taken second place, and filler is most thick in some intermediate diameter range,
In this way the cooling efficiency of cooling tower can be improved with the heat and mass transfer performance in uniform column everywhere.
Utility model content
Method in above patent document is not directed to aerodynamic field in the tower under crosswind environment and carries out optimization processing.But
Be the utility model discovery: when there is extraneous crosswind, the aerodynamic field inside cooling tower is more complicated, and cooling tower is everywhere
Performance it is more unbalanced, the pool surface that especially catchments will form the region " falcate " Gao Shuiwen, i.e. cooling tower penalty area
It is changed into " falcate ".For this purpose, the utility model provides a kind of wet cooling tower with falcate filler, to solve crosswind ring
Cooling problem caused by " falcate " penalty area in cooling tower under border.
To achieve the above object, the utility model discloses following technical proposals:
A kind of wet cooling tower with falcate filler, comprising: tower, Central Shaft and curved filler region；In described
Centre vertical shaft is located at tower center, and the filler region is between tower and Central Shaft, and filler region is divided into " bent moon
Packing area other than shape " packing area and " falcate "；The thickness of " falcate " packing area is greater than packing area other than " falcate "
Thickness；" falcate " packing area is located at the region " falcate " Gao Shuiwen caused by crosswind.
As further technical solution, the wind direction of the position of " falcate " packing area and geometric dimension and extraneous crosswind and
Wind speed has relationship, generally can be always true according to the long-term wind speed and direction in cooling tower location or the corresponding wind speed and wind of most bad working environments
It is fixed.Alternatively, high water temperature region can also be determined using thermal imaging system, and then add to the filler in the region according to the actual situation
Thickness setting.
As further technical solution, the thickness relationship of packing area other than " falcate " packing area and " falcate "
Are as follows: 1.2-1.3 times.
As further technical solution, " falcate " packing area is located at following region: centered on Central Shaft,
Using crosswind wind direction as symmetry axis, along symmetry axis arranged on left and right sides and with symmetry axis is at angle theta extends to form two to Central Shaft periphery
Extended line, is connected the endpoint of two extended lines with curve；The endpoint is one end far from Central Shaft, the song
Line is two, is distributed in the front and rear sides of two extended lines, to form " falcate " packing area, the angle, θ is acute angle.
As further technical solution, when the wind speed is 4-6m/s, the length L=45~50m, θ of the extended line
=75~80 °, and the L is the projected length of extended line on the horizontal axis.
As further technical solution, when the wind speed is 4m/s, the length L=45m of the extended line, θ=80 °,
And the L is the projected length of extended line on the horizontal axis.
As further technical solution, when the wind speed is 6m/s, the length L=50m of the extended line, θ=75 °,
And the L is the projected length of extended line on the horizontal axis.
Compared with prior art, the utility model achieves following the utility model has the advantages that the utility model is directed to cooling tower in side
Operating condition under wind, it is contemplated that " falcate " penalty caused by two kinds of factors of this body structure of cooling tower and extraneous crosswind
Area proposes " falcate " non-technical concept for being arranged at an equal altitude filler, using cooling tower " falcate " filler of the utility model
The air-water contact time in area is elongated, and recirculated water temperature drop improves in this region, and cooling performance is enhanced.Meanwhile it is empty in the region
Temperature, which rises, to be improved, and atmospheric density reduces, so that draft increases, and the increase of depth of packing will increase air flowing in the region
Resistance, therefore the aerodynamic field variation of entire cooling tower is unobvious, thus in the heat and mass that will not influence other regions
On the basis of enhance the whole cooling performance of cooling tower, improve recirculated water temperature drop.
