Description
Technical field
The invention belongs to fire/nuclear power station indirect air cooling field, particularly to the gas side current-equalizing system of the vertical triangular form radiator of a kind of indirect cool tower。
Background technology
Along with being becoming tight the day of China's water resource and its management system increasingly strict, gravity-flow ventilation indirect dry cooling tower, as a kind of type of cooling in power station, is applied to the drought and water-scarce area such as NORTHWEST CHINA, North China gradually。Recirculated water in usual indirect dry cooling tower in the way of heat convection, transfers heat to surrounding air by vertical triangular form radiator。Therefore its cooling limit is surrounding air dry-bulb temperature, and cooling capacity is relatively low。
Show according to existing research, the cooling capacity of gravity-flow ventilation indirect cool tower is affected bigger by air intake air flow field structure and intake, environmental natural wind then directly changes the size into tower air flow field structure and intake thereof, and finally affects the overall cooling performance of indirect cool tower。
As it is shown in figure 1, be existing indirect air cooling power station gravity-flow ventilation indirect dry cooling tower, vertical triangular form radiator 1 is arranged at air inlet outside upright。As in figure 2 it is shown, be half tower cross sectional representation of the vertical triangular form radiator arrangement of existing indirect cool tower。As shown in Figure 2, the vertical triangular form radiator of indirect cool tower is formed along indirect cool tower circumference vertically layout by several cooling triangles。Along indirect cool tower half tower circumference, vertical triangular form radiator can be divided into five cooling sectors, then can be divided into ten sectors along whole tower circumference。For the impact of research environment natural wind, the circumferential angle, θ of the cooling triangle of most for windward side head end is defined 0 °, circumferential angle of last cooling triangle of leeward side is defined as 180 °。Predefining based on this, the circumferential angle of five, indirect cool tower half tower cooling sector is followed successively by: the first sector 4, the fan angle θ contained ranges for 0 °～36 °；Second sector 5, the fan angle θ contained ranges for 36 °～72 °；3rd sector 6, the fan angle θ contained ranges for 72 °～108 °；4th sector 7, the fan angle θ contained ranges for 108 °～144 °；5th sector 8, the fan angle θ contained ranges for 144 °～180 °。
As it is shown on figure 3, be existing indirect cool tower one cooling triangle cross-sectional structure schematic diagram, it is made up of two mutually isostructural cooling columns and a shutter 14。From the figure 3, it may be seen that shutter 14 is arranged horizontally in the air inlet vertically cooling down triangle, play the effect regulating intake。Shutter keeps standard-sized sheet in summer, opens in relatively cold season joint part。As in figure 2 it is shown, each cooling triangle is evenly arranged along indirect cool tower circumference。As shown in Figure 2 and Figure 3, namely the horizontal plane projection line cooling down triangle intermediate symmetry face 16 crosses the radial direction extended line 9 at indirect cool tower center 10。As shown in Figure 4, for the cross-sectional structure schematic diagram of a cooling column of existing cooling triangle。As shown in Figure 4, the finned-tube bundle formula radiator that cooling column adopts, it is generally 4 combs or 6 combs, wherein side is upper water side pipe bundle, and opposite side is lower water side pipe bundle。
Indirect cool tower is respectively cooled down the impact of the cooling performance of triangle by environmental natural wind 3 for convenience of description, and existing two cooling columns by cooling triangle are predefined as θ respectively-1Cooling column 11 and θ+2Cooling column 17, wherein θ-1Cooling column 11 is positioned at the circumference less side of angle, θ, θ+2Cooling column 17 is positioned at the circumference bigger side of angle, θ。When affecting without environmental natural wind, surrounding air almost all can approximately radially enter in cooling triangle shutter inner chambers by natural flow, and flows through θ successively-1Cooling column 11 and θ+2Cooling column 17, thus completing heat exchange。In cooling triangle, air flow field structure is symmetrical about cooling triangle intermediate symmetry face 16, its θ-1Cooling column 11 and θ+2Cooling column 17 cooling performance is identical。
According to actual operating state, indirect cool tower is always subjected to the impact of either large or small environmental natural wind, and the environmental natural wind wind speed of indirect cool tower design is generally taken as 4m/s or 6m/s。As it is shown in figure 5, be several cooling triangle air flow field structural representations of tower side the 3rd sector 6 of indirect cool tower under 4m/s crosswind。As shown in Figure 5, the environment crosswind of 4m/s causes tower side air circumferential speed relatively big, so that the air intake deviation cooling triangular symmetrical face 16 certain angle θ at cooling triangle air intake placed, and at the θ of cooling triangle-1Cooling column 11 inlet side causes low speed whirlpool, reduces θ-1The ventilation of cooling column 11, weakens θ-1The cooling performance of cooling column 11。As shown in Figure 6, for the θ of several cooling triangles-1The lower water side pipe bundle exit water temperature 20 of cooling column 11 and θ+2The lower water side pipe bundle exit water temperature 21 of cooling column 17。It will be appreciated from fig. 6 that θ-1The outlet water temperature average specific θ of cooling column 11+2The outlet water temperature of cooling column 17 is high about 3.5 DEG C。
As it is shown in fig. 7, be under the environment crosswind of 4m/s, indirect cool tower half tower respectively cools down triangle air intake place air intake degree of being radially offset from θdCircumferential change curve。As shown in Figure 7, within the scope of the tower side of the second sector the 5, the 3rd sector 6 and the 4th sector 7, the air intake irrelevance of cooling triangle is all relatively larger, substantially within 45 °～70 ° scopes, much larger than the air intake irrelevance of cooling triangle in windward side the first sector 4 and leeward side the 5th sector 8。Under environment crosswind according to above-mentioned 4m/s, the air flow field structure of the 3rd sector 6 and the result of leaving water temperature distribution are analogized: because the second, the 4th sector and the 3rd sector have bigger air intake irrelevance equally, environment crosswind equally can at θ-1Cooling column 11 inlet side causes velocity air eddy region, thus reducing its air intake flow velocity, then reduces θ-1The ventilation of cooling column 11, hence in so that θ-1The cooling performance of cooling column 11 weakens, and ultimately causes θ-1The outlet water temperature of cooling column 11 is significantly raised, also makes cooling triangle overall performance accordingly weaken。
Therefore a kind of gas effluent field current-equalizing system suitable in the vertical triangular form radiator of indirect cool tower is researched and developed, it is optimized by tower side respectively being cooled down the existing air flow field structure of triangle, reduces its air intake irrelevance, and then reduce the environmental natural wind adverse effect to cooling triangle side, tower side cooling column cooling performance, realize this side cooling column cooling performance and the corresponding raising cooling down triangle entirety cooling performance, and and then improve the overall cooling performance of indirect cool tower under environment crosswind, it has also become a kind of problem anxious to be resolved。
