Normal 8 × 8 or 7 × 8 the air cooling cell layout mode that adopts of existing 600MW Direct Air-cooled Unit, normal 5 × 6 the arrangement that adopts of 300MW unit, the axial flow blower axis of each air cooling unit, perpendicular to ground, causes environment beam wind wind direction almost vertical with axial flow blower axis.Under ambient wind effect, axial flow blower inlet flow distortion aggravation, fan performance degradation, cooling air delivery is reduced, direct air cooling system thermal performance worsens, especially the fluid interchange hydraulic performance decline that is in air cooling unit, upstream, Air-Cooling Island windward side is obvious, even occurs the phenomenon that hot blast flows backwards, and has a strong impact on unit safety economical operation.There are some researches show, by adopting surroundings wind field inducing technology, installation environment wind deflector, can improve upstream, windward side air cooling unit stream and move hot property, improves Air-Cooling Island cooling capacity.
From fixed environment wind field apparatus for deivation being installed to meet the demand of safe operation of power plant, the present invention proposes a kind of support and overhung construction of direct air cooling system surroundings wind field inducing device, may cause the safety problems such as wind field apparatus for deivation comes off because of vibration or ambient wind effect to overcome in air cooling system running.
Summary of the invention
The object of the invention is to propose a kind of fixed structure for direct air cooling system surroundings wind field inducing device locus, it is characterized in that, the fixed structure of described surroundings wind field inducing device locus comprises ambient wind deflector supporting construction and ambient wind deflector overhung construction.
Described surroundings wind field inducing device is made up of ambient wind deflector supporting construction, ambient wind deflector overhung construction and three layers of measure-alike ambient wind deflector of upper, middle and lower of being welded in ambient wind deflector supporting construction.
Described ambient wind deflector supporting construction adopts angle steel and T-shaped connecting plate to be welded, and be that starting point is upwards equidistantly welded on long fulcrum bar and short strut by the lower end of long and short pole respectively, deflector supporting construction on long and short pole is corresponding one by one, its relative position is determined by length pole lower end difference in height, makes the supporting construction of relative position between fixed environment wind deflector be divided into upper, middle and lower three parts.
Described ambient wind deflector overhung construction adopts H shaped steel to be welded, concrete structure be first by two cross support arms by a long fulcrum bar and parallel coupling together of short strut, make the upper end of long and short pole concordant; Then, then by a cross support arm oblique fulcrum bar is welded on short strut; Wherein each cross support arm, long fulcrum bar, short strut and oblique fulcrum bar must be in one plane, and the upper end of long fulcrum bar, short strut and oblique fulcrum bar is on a horizontal line; These three upper ends and Air-Cooling Island steel truss couple together, and reach the object of fixed environment wind field apparatus for deivation locus.
The invention has the beneficial effects as follows by the installation of air cooling system ambient wind deflector supporting construction, realized the fixing of ambient wind deflector relative position; By the installation of overhung construction, realize determining of connection between ambient wind deflector and Air-Cooling Island steel truss and deflector dimensional orientation, avoid in air cooling system running causing the safety problems such as wind field apparatus for deivation comes off because of vibration or ambient wind effect, ensured the safe operation of Direct-air-cooling Power Plants.
