Description
Technical field
The invention belongs to the energy source and power technical field, the windproof guiding device in particularly a kind of power station direct air-cooling island.
Background technology
In northern China, can near coal-mine power plant location water resource serious lack especially be difficult to bear big water consumption in dry season more, thereby have influence on the problem that build power plant.Direct Air-Cooling Technology; Because the water saving characteristics that it is outstanding; Can solve the bottleneck problem of water resource well, the used Direct Air-Cooled of this technology island comprises tens air cooling blower fans by column-row arrangement, utilizes surrounding air that direct air cooled condenser is carried out forced-convection heat transfer.Facts have proved that direct air cooled condenser heat exchange effect very easily receives the external environment factor affecting, main cause is that ambient wind can cause the direct air cooled condenser heat exchange to worsen, and influences the safety and the economy operation on Direct Air-Cooled island.Ambient wind is one of research air cooling technique problem demanding prompt solution to the influence on Direct Air-Cooled island.
Existing research shows that surroundings wind field is unfavorable for the air draught of air cooling blower fan, and ambient wind velocity is big more, and ambient wind is big more to the influence of blower fan suction air volume, and is also big more to direct air cooled condenser heat exchange influential effect.Existing air cooling system is the installing windbreak on platform top, air cooling island usually, can suppress the harmful effect and the hot air reflux phenomenon of ambient wind to a certain extent; But under the bigger situation of ambient wind, the zone that facings the wind of air cooling island platform below can form negative pressuren zone, and the suction air volume of this air cooling unit, zone blower fan is obviously reduced, even air occurs and pour in down a chimney phenomenon.The method that can take is below the platform of air cooling island, guiding device to be installed; Like application number is the Chinese patent disclosed " installing the power station direct air-cooling condenser of air intake guide device additional " of 200610040699.X; It comprises heat-exchanging tube bundle, windbreak (1), blower fan crowd (2), steel structure platform (3) and column (4), and steel structure platform (3) upwards is connected on the column (4), and heat-exchanging tube bundle and blower fan crowd (2) are arranged on the steel structure platform (3); Blower fan crowd (2) is arranged in the heat-exchanging tube bundle below; Windbreak (1) vertically upwards is arranged in the periphery of steel structure platform (3), and steel structure platform (3) periphery of its windbreak (1) below vertically is furnished with air intake guide device (5) downwards, is used to change the direction that air gets into the peripheral blower fan suction inlet of air cooling tubes condenser; Make harmful natural wind become useful natural wind, improve the performance of air cooling tubes condenser.Described air intake guide device (5) is made up of blade (5.1), coupled connecting rod (5.2) and the control lever (5.3) that can move up and down.It can improve the facing the wind intake of regional blower fan of periphery, air cooling island.But the blade of installing on the air cooling island (5.1) is negligible amounts (Fig. 5); And there is negative pressure region at blade (5.1) rear; Make ambient wind the whirlwind backflow phenomenon occur at the guide vane rear; Worsened the flow field of inner air cooling blower fan unit, reduced the intake of the inner blower fan in air cooling island, ambient wind reduces this problem of air cooling system suction air volume and fails all the time to obtain effectively thoroughly to solve.It uses a control lever (5.3) in addition, is prone to make blade (5.1) mass motion during adjusting, and the angular range of adjusting is limited, the water conservancy diversion deleterious; Blade (5.1) two summits are unfixing, are prone to swing when ambient wind is big, influence the water conservancy diversion effect; In addition, do not provide the adjusting angle scope of blade (5.1) and the vertical distance of adjacent blades (5.1) in the document yet.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, and it is reasonable to propose a kind of structure, is connected firmly; Regulative mode is flexible; Surroundings wind field is played guide functions, effectively improve the peripheral blower fan intake in air cooling island, do not influence the inner blower fan intake in air cooling island; Weaken the harmful effect of ambient wind, improve the windproof guiding device in power station direct air-cooling island of unit operation security and economy Direct Air-Cooled unit, air cooling island heat transfer characteristic.
The technical scheme that the present invention solves the problems of the technologies described above employing is: the windproof guiding device in a kind of power station direct air-cooling island; It is peripheral that it is arranged in the air cooling island vertically downward; Be installed between platform below, air cooling island and the ground; It is characterized in that: it comprises windproof water conservancy diversion net, fixing branch strut and regulates and restrict that fixing branch strut and adjusting rope are fixed on respectively between air cooling island platform lower edge and the ground, and the fixing branch strut is positioned at regulates the rope inboard; Windproof water conservancy diversion net is made up of porous net sheet and frame, and porous net sheet is fixed on the quadrangle frame.The some online lower leafs of windproof water conservancy diversion are arranged between fixing branch strut and the adjusting rope; Wherein two angles, frame the inside are connected fixing with the fixing branch strut; Two angles, frame outside are connected with the adjusting rope, according to change of wind velocity, through lifting the angle of inclination of regulating the windproof water conservancy diversion net of rope adjustment up and down.
Porous net sheet according to the invention is woven by nylon rope, and the nylon rope diameter is 0.2 ~ 1cm, and porous net sheet aperture is between 12 ~ 36 orders.
Windproof water conservancy diversion net according to the invention lateral has a down dip, and the angle of inclination is between level and downward 45 °.
The online lower floor of windproof water conservancy diversion according to the invention interlamellar spacing is 1.5 ~ 2m, and the about width of windproof water conservancy diversion net is between 2 ~ 3m.
The adjusting according to the invention end of restricting is fixed according to adjusting position, and the other end is regulated through manual or electric device.
Mounting arrangements of the present invention is below the platform of air cooling island and between the ground; Regulate the angle of inclination of water conservancy diversion net according to change of wind velocity, make ambient wind wind direction from the outside, air cooling island by becoming under oblique obliquely, wind speed is high more; The inclination angle is big more, windproof water conservancy diversion wire side level when calm.The invention has the advantages that; Under the ambient wind velocity condition,, change the wind direction of ambient wind through changing the angle of the windproof guiding device in power station direct air-cooling island; Make ambient wind wind direction from the air cooling island outside by becoming under oblique obliquely, ambient wind is played guide functions; Can reduce simultaneously the ambient wind kinetic energy of air cooling island platform lower, transverse motion, weaken the negative pressure region negative pressure, improve the air inflow of ambient wind outer peripheral areas air cooling unit cooling air, reduce hot air reflux, improve these air cooling unit heat transfer characteristics; Reduced the influence of ambient wind, improved the security and the economy of unit operation the peripheral air cooling blower fan service behaviour in air cooling island.Regulative mode of the present invention is flexible, and windproof water conservancy diversion net is connected firmly, and ambient wind can not blown windproof water conservancy diversion net; Air cooling island platform has all carried out water conservancy diversion to the air on ground down, is improving peripheral blower fan intake simultaneously, can the blower fan of inner air cooling unit, air cooling island not had a negative impact.
