Abstract
The utility model discloses an air duct for a cooling tower, which includes a group of air duct plates, wherein a cylindrical cylinder body is formed and surrounded by the air duct plates connected through bolts. The air duct for the cooling tower disclosed by the utility model has simple structure, long service life and strong pressure resistance, operates stably and saves energy.
Description
Technical field
The utility model relates to a kind of ventilating duct, particularly a kind of cooling tower ventilating duct.
Background technology
The rigidity of the ventilating duct of common cooling tower does not reach designing requirement, when rotating, blower fan can cause the vibrations of ventilating duct, shake fairly obviously, have a strong impact on air duct service life, become an important research content thereby ventilating duct developed with research.
The utility model content
Goal of the invention:, the utility model discloses the stable cooling tower ventilating duct of a kind of resistance to compression at the deficiencies in the prior art.
Technical scheme: the utility model discloses a kind of cooling tower ventilating duct, comprise one group of tube plate, described tube plate surrounds a cylindric cylindrical shell; Described tube plate connects by bolt.
The preferred hex bolts of described bolt; Make the connection of ventilating duct more solid and reliable, improved the stability of ventilating duct.
Described tube plate is that two ends upwarp, the sheet material that the centre falls in, and the upper end of described tube plate is longer than the lower end.More meet principle of dynamics, the air outlet slit kinetic energy rejection is less, and the ventilation of cooling tower obviously increases, thereby the cooling tower cooling-down effect improves a lot.The thermal performance of cooling tower improves greatly, has saved energy consumption.Ventilating duct top is the rounding platform, and there is a cylinder changeover portion at the middle part at the blower fan place, and the bottom is the rotary body that specific curves rotation forms, the giving full play to of ventilating duct effect; And can adjust wall thickness by design, manufacturing, and make ventilating duct be in the rational natural frequency of vibration, avoid resonance region with tower body.
It is main shell structure that the structural design of ventilating duct integral body makes cylindrical shell become tension (pressure), and has obtained good local anti-bending strength again, and the actual working state that coincide has improved the dependability of ventilating duct effectively.
Beneficial effect: the disclosed cooling tower ventilating duct of the utility model, simple in structure, stable, long service life, energy-conservation, anti-pressure ability is strong.
Description of drawings
Accompanying drawing is the structural representation of cooling tower ventilating duct.
The specific embodiment
The utility model is further explained below in conjunction with accompanying drawing.
The utility model discloses a kind of cooling tower ventilating duct, comprise one group of tube plate 1, described tube plate 1 surrounds a cylindric cylindrical shell; Described tube plate 1 connects by bolt 2.
Described bolt 2 preferred hex bolts; Make the connection of ventilating duct more solid and reliable, improved the stability of ventilating duct.
Described tube plate 1 is for two ends upwarp, the sheet material that the centre falls in, and the upper end of described plate 1 is longer than the lower end.More meet principle of dynamics, the air outlet slit kinetic energy rejection is less, and the ventilation of cooling tower obviously increases, thereby the cooling tower cooling-down effect improves a lot.The thermal performance of cooling tower improves greatly, has saved energy consumption.Ventilating duct top is the rounding platform, and there is a cylinder changeover portion at the middle part at the blower fan place, and the bottom is the rotary body that specific curves rotation forms, the giving full play to of ventilating duct effect; And can adjust wall thickness by design, manufacturing, and make ventilating duct be in the rational natural frequency of vibration, avoid resonance region with tower body.
Ventilating duct is made by monolithic, the multi-disc assembling.High-quality 189# unsaturated-resin, the non-twist glass fabric of alkali-free are adopted in the manufacturing of ventilating duct, and 33# resin gel coat is adopted on the surface.The compression moulding of negative and positive mould is adopted in the manufacturing of ventilating duct, and the two sides is smooth, the precision height, and strength of glass obviously increases, long service life, flowing resistance obviously reduces, and the resistance to overturning of air duct is good.
The utility model provides a kind of thinking and method of cooling tower ventilating duct; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications; these improvements and modifications also should be considered as protection domain of the present utility model, and all available prior art of each part not clear and definite in the present embodiment is realized.
