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 utility model proposes a kind of support and overhung construction of direct air cooling system surroundings wind field inducing device, to overcome in air cooling system running, may cause the safety problems such as wind field apparatus for deivation comes off because of vibration or environment wind action.
Utility model content
The purpose of this utility model be in air cooling system running may because of vibration or ambient wind effect cause that the safety problems such as wind field apparatus for deivation comes off propose a kind of mounting structure for direct air cooling system surroundings wind field inducing device, it is characterized in that, the mounting structure of described surroundings wind field inducing device comprises ambient wind deflector supporting construction and ambient wind deflector overhung construction.
Described surroundings wind field inducing device is comprised of with the three layers of measure-alike ambient wind deflector of upper, middle and lower that are welded in ambient wind deflector supporting construction ambient wind deflector supporting construction and ambient wind deflector overhung construction.
Described ambient wind deflector supporting construction adopts angle steel and T-shaped connecting plate to be welded, and take respectively the lower end of long and short pole and be upwards equidistantly welded on long fulcrum bar and short strut as starting point, deflector supporting construction on long and short pole is corresponding one by one, its relative position is determined by long and short pole lower end difference in height, makes the deflector 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 beneficial effects of the utility model are by the installation of air cooling system ambient wind deflector supporting construction, have realized the fixing of ambient wind deflector relative position; By the installation of overhung construction, realized determining of connection between ambient wind deflector and Air-Cooling Island steel truss and deflector dimensional orientation, avoided 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, guaranteed the safe operation of Direct-air-cooling Power Plants.
