Description
Technical field
The invention belongs to fire/nuclear power station indirect air cooling field, particularly a kind of pillar cooling tube bundle with wedge gap.
Background technology
Gravity-flow ventilation indirect dry cooling tower, has the excellent characteristic of saving water and energy of zero evaporation water consumption and zero blower fan power consumption, becomes the main cooling device of the drought and water-scarce area fired power generating unit recirculated water such as NORTHWEST CHINA, North China gradually.Gravity-flow ventilation indirect dry cooling tower, hereinafter referred to as indirect cool tower, is made up of radiator and tower cylinder, and wherein radiator is finned heat radiation tube bank.Along perpendicular the putting of indirect cool tower, finned heat radiation tube bank can arrange that circumference is combined into triangle cooling unit below tower cylinder, also can become A shape framework cooling unit in tower cylinder lower horizontal arrangement combinations.
In the indirect cool tower that radiator tower is vertically arranged outward, triangle cooling unit is composed in parallel by two cooling studs, and each cooling stud is composed in series by 3 ~ 4 cooling tube bundles again, conventional chilling tube bank for base tube row be the finned-tube bundle of 4 or 6.In indirect cool tower horizontally disposed in radiator tower, frame type A cooling unit is composed in parallel by two cooling studs, and each cooling stud comprises the cooling tube bundle of 2 ~ 4 series connection.
Recirculated water flowing in the finned heat radiation tube bank of indirect cool tower, in the mode of convection heat transfer' heat-transfer by convection, transfers heat to the surrounding air between fin.Now there are some researches show, environmental natural wind directly affects air inlet region at the bottom of indirect cool tower tower and tower top outlet regional air aerodynamic field, reduces the heat transfer property of tower side cooling tube bundle, is degrading the overall cooling performance of indirect cool tower.
As shown in Figure 1, for existing cold power station radiator cooling unit triangular in shape erects the indirect cool tower putting layout, the radiator 1 that triangle cooling unit forms is arranged at the air inlet outside upright of tower cylinder 2.As shown in Figure 2, be the arrangement schematic diagram in the overall cross section of existing indirect cool tower cooling triangular form radiator.As shown in Figure 2, along indirect cool tower half tower circumference, radiator can be divided into five to cool sector, and whole tower is totally ten sectors.Along indirect cool tower circumference, mark each cooling sector clockwise successively: the first sector 3, the fan angle θ scope contained is 0 ° ~ 36 °; Second sector 4, the fan angle θ scope contained is 36 ° ~ 72 °; 3rd sector 5, the fan angle θ scope contained is 72 ° ~ 108 °; 4th sector 6, the fan angle θ scope contained is 108 ° ~ 144 °; 5th sector 7, the fan angle θ scope contained is 144 ° ~ 180 °.
As the cross section structure schematic diagram of Fig. 3 triangle cooling unit that form to by existing cooling stud, comprise the first identical cooling stud 8 of structure and the second cooling stud 9, two cooling stud side endvertex intersects, angle is between 40 ° ~ 60 °; The main air inlet 10 forming triangle cooling unit is opened in the two non-crossing sides of cooling stud, and arranges shutter in air inlet, and shutter plays the effect of control wind, can prevent cooling stud from restraining in the winter time and freeze bursting by freezing.
When affecting without environmental natural wind, surrounding air 11 almost all can enter triangle cooling unit along the radial natural flow of indirect cool tower, and flows through the first cooling stud 8 and the second cooling stud 9 simultaneously, completes heat exchange.In triangle cooling unit, air flow field structure is symmetrical about cooling unit center line, and the first cooling stud 8 is identical with the second cooling stud 9 cooling performance.But for the many rows finned-tube bundle in same cooling tube bundle in a cooling stud, its finned tube near shutter air inlet side first carries out heat exchange with inflow air, the air themperature making its downstream finned tube corresponding raises, and causes the finned tube heat radiation away from shutter air inlet side not enough.
And during indirect cool tower actual motion, environmental natural wind always exists, and indirect cool tower cooling performance is had a negative impact.For ensureing indirect cool tower cooling performance, usual indirect cool tower design environment crosswind wind speed is taken as 4m/s or 6m/s.As the cross section aerodynamic field that Fig. 4 is indirect cool tower tower side the 3rd sector part triangle cooling unit under 4m/s environment crosswind.For the impact of 4m/s environment crosswind, as shown in Figure 4, the environment crosswind of 4m/s causes tower side air circumferential speed larger, tower side triangle cooling unit air intake and shutter place air intake wind direction is made to depart from cooling unit plane of symmetry certain angle θ d, and cause comparatively Maelstrom in the first cooling stud 8 inlet side of cooling unit, this will reduce the ventilation of the first cooling stud 8, weakens the cooling performance of the first cooling stud 8, finally causes the outlet water temperature of the first cooling stud 8 obviously to raise.
Therefore, under environment crosswind condition, reduce the adverse effect of low velocity eddy region in the triangle cooling unit of tower side, increase cooling unit ventilation, reduce and even eliminate the low velocity eddy region in cooling unit, the cooling performance of the corresponding cooling tube bundle of strengthening cooling stud, and and then improve triangle cooling unit and the overall cooling performance of indirect cool tower, become the problem that need solve.
