Description
Technical field
The application is the (applying date: 2015-4-23, title: a kind of with wedge gap of Chinese patent 201510201859.3
Pillar cooling tube bundle) divisional application.
The invention belongs to fire/nuclear power station indirect air cooling field, in particular to what a kind of triangle cooling unit was arranged vertically
Indirect cool tower and its cooling means.
Background technique
Gravity-flow ventilation indirect dry cooling tower, with zero evaporation water consume and zero blower power consumption excellent characteristic of saving water and energy, by
Gradually become the main cooling device of the drought and water-scarce areas fired power generating unit recirculated waters such as northwest China, North China.Gravity-flow ventilation is indirectly empty
Cold tower, hereinafter referred to as indirect cool tower, are made of radiator and tower, and wherein radiator is finned heat dissipation tube bank.Finned heat dissipation
Tube bank can be vertically arranged arrangement along indirect cool tower below tower and circumferentially be combined into triangle cooling unit, can also be in tower lower horizontal cloth
It sets and is combined into A-frame cooling unit.
In the indirect cool tower arranged vertically outside radiator tower, triangle cooling unit is composed in parallel by two cooling columns, often
A cooling column is composed in series by 3~4 cooling tube bundles again, and conventional chilling tube bank is the finned-tube bundle that base tube number of rows is 4 or 6.?
In radiator tower in horizontally disposed indirect cool tower, frame type A cooling unit is composed in parallel by two cooling columns, each cooling column
Including 2~4 concatenated cooling tube bundles.
Recirculated water flowing in the finned heat dissipation tube bank of indirect cool tower, in a manner of convective heat transfer, transfers heat to wing
Surrounding air between piece.Existing research shows that environmental natural wind directly affects indirect cool tower tower bottom air inlet region and tower top outlet
Regional air aerodynamic field reduces the heat transfer property of tower side cooling tube bundle, is degrading indirect cool tower entirety cooling performance.
As shown in Figure 1, the indirect cool tower of arrangement, triangle are vertically arranged with radiator cooling unit triangular in shape for existing cold power station
Radiator 1 composed by shape cooling unit is arranged in the air inlet outside upright of tower 2.As shown in Fig. 2, cold for existing indirect cool tower
But the arrangement schematic diagram in the whole cross section of triangular form radiator.As shown in Figure 2, circumferential along half tower of indirect cool tower, radiator
Five cooling sectors can be divided into, whole tower totally ten sectors.Along indirect cool tower circumferential direction, each cooling sector is successively marked clockwise: first
Sector 3, the fan angle θ range covered are 0 °~36 °；Second sector 4, the fan angle θ range covered are 36 °~72 °；Third sector 5,
The fan angle θ range covered is 72 °~108 °；4th sector 6, the fan angle θ range covered are 108 °~144 °；5th sector 7 is contained
The fan angle θ range of lid is 144 °~180 °.
It include structure phase such as the cross section structure schematic diagram that Fig. 3 is triangle cooling unit composed by existing cooling column
Same the first cooling column 8 and the second cooling column 9, the intersection of two cooling column side endvertexes, angle is between 40 °~60 °；Two is cooling
The main air inlet 10 to form triangle cooling unit is opened in the non-intersection side of column, and shutter, shutter is arranged in air inlet
Play the role of controlling wind, can prevent cooling column tube bank from freezing bursting by freezing in winter.
When no environmental natural wind influences, 11 almost all of surrounding air can radially flow into naturally triangle along indirect cool tower
Shape cooling unit, and the first cooling column 8 and the second cooling column 9 are simultaneously flowed through, complete heat exchange.Air stream in triangle cooling unit
Field structure is symmetrical about cooling unit center line, and the first cooling column 8 is identical with 9 cooling performance of the second cooling column.But for one
For multiple rows of finned-tube bundle in cooling column in same cooling tube bundle, the finned tube close to shutter air inlet side is first and flows into
Air exchanges heat, and makes the corresponding air themperature raising of finned tube downstream, leads to the finned tube far from shutter air inlet side
Heat dissipation is insufficient.
And when indirect cool tower actual motion, what environmental natural wind was constantly present, and it is unfavorable to the generation of indirect cool tower cooling performance
It influences.To guarantee that indirect cool tower cooling performance, usual indirect cool tower design environment crosswind wind speed are taken as 4m/s or 6m/s.If Fig. 4 is 4m/
The cross section aerodynamic field of indirect cool tower tower side third sector part triangle cooling unit under s environment crosswind.With 4m/s environment
For the influence of crosswind, as shown in Figure 4, the environment crosswind of 4m/s causes tower side air circumferential speed larger, so that tower side triangle
Wind direction is entered the wind at shape cooling unit air intake, that is, shutter deviates cooling unit plane of symmetry certain angle θd, and in cooling unit
8 inlet side of the first cooling column cause compared with Maelstrom, this will reduce the ventilation quantity of the first cooling column 8, weaken the first cooling column 8
Cooling performance, the outlet water temperature for ultimately causing the first cooling column 8 is significantly raised.
Therefore, under the conditions of environment crosswind, reduce the adverse effect of low velocity eddy region in the triangle cooling unit of tower side,
Increase cooling unit ventilation quantity, reduce or even eliminate the low velocity eddy region in cooling unit, strengthens cooling column and correspond to cooling tube
The cooling performance of beam, and triangle cooling unit and indirect cool tower entirety cooling performance are improved in turn, it has also become what need be solved asks
Topic.
