Abstract
The invention discloses a kind of gas fired-boiler chimney denoising structure, including: the outer wall of described chimney is coated with damping sheet, rock cotton board, centrifugally glass-wool, glass-fiber-fabric and backplate the most successively；The thickness of described damping sheet is 5mm 7mm, and the thickness of described rock cotton board is 60mm 70mm, and the thickness of described centrifugally glass-wool is 60mm 75mm, and the thickness of described glass-fiber-fabric is 3mm 4mm, and the thickness of described backplate is 0.6mm 0.9mm.Damping noise reduction is effective, low cost, and when chimney is carried out noise reduction process, wrapping is convenient, it is possible to be widely used in the noise reduction process of the gas fired-boiler chimney of various model.
Description
Technical field
The present invention relates to gas fired-boiler noise reduction technology field, especially, relate to a kind of gas fired-boiler chimney denoising structure.
Background technology
Operationally, wind and the air-flow of chimney discharge that combustor blows into are very strong, and chimney wall is relatively thin, air-flow for gas fired-boiler
Easily shaking when quickly flowing, vibrations will produce noise.For reducing noise, general noise reduction measure: 1, install deafener additional,
Deafener principle reduce chimney draft intensity exactly, reduce vibrations, but be so unfavorable for the quick drain of air-flow；2, thicken
The wall thickness of steel stack, the cost of this noise reduction mode is high；3, sound insulation shock-damping structure is set up at chimney connecting portion besides, this
The mode of kind cannot eliminate the vibrations of chimney, and the effect of noise reduction is undesirable.
Summary of the invention
Present invention aim at providing a kind of gas fired-boiler chimney denoising structure, to reduce making an uproar of gas fired-boiler chimney generation
Sound.
For achieving the above object, the present invention provides a kind of gas fired-boiler chimney denoising structure, including: the outer wall of described chimney
It is coated with damping sheet, rock cotton board, centrifugally glass-wool, glass-fiber-fabric and backplate the most successively；The thickness of described damping sheet is
5mm-7mm, the thickness of described rock cotton board is 60mm-70mm, and the thickness of described centrifugally glass-wool is 60mm-75mm, described glass
The thickness of cloth is 3mm-4mm, and the thickness of described backplate is 0.6mm-0.9mm.
Further, described damping sheet is rubber damping plate.
Further, described backplate is galvanized sheet.
The method have the advantages that
Damping noise reduction is effective, low cost, and when chimney is carried out noise reduction process, wrapping is convenient, it is possible to be widely used in various
The noise reduction process of the gas fired-boiler chimney of model.
Accompanying drawing explanation
Below with reference to figure, the present invention is further detailed explanation.The accompanying drawing of the part constituting the application is used for
Thering is provided a further understanding of the present invention, the schematic description and description of the present invention is used for explaining the present invention, is not intended that
Inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of gas fired-boiler chimney denoising structure preferred embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
Referring to Fig. 1, the preferred embodiments of the present invention provide a kind of gas fired-boiler chimney denoising structure, including: described
The outer wall of chimney 1 is coated with damping sheet 2, rock cotton board 3, centrifugally glass-wool 4, glass-fiber-fabric 5 and backplate 6 the most successively；Described
The thickness of damping sheet 2 is 5mm-7mm, and the thickness of described rock cotton board 3 is 60mm-70mm, and the thickness of described centrifugally glass-wool 4 is
60mm-75mm, the thickness of described glass-fiber-fabric 5 is 3mm-4mm, and the thickness of described backplate 6 is 0.6mm-0.9mm.
Damping sheet 2, rock cotton board 3, centrifugally glass-wool 4 form damping sound-absorbing composite bed with glass-fiber-fabric 5, greatly reduce chimney
Vibrations, there is good noise reduction, backplate 6 uses hard material, plays a protective role damping sound-absorbing composite bed, simultaneously
Play the effect strengthening chimney wall thickness, reduce the vibration frequency of chimney wall.This mode, low cost, chimney is carried out at noise reduction
During reason, wrapping is convenient, it is possible to be widely used in the noise reduction process of the gas fired-boiler chimney of various model.
Preferably, for improving the damping noise reduction effect of damping sheet 2, facilitate the wrapping of damping sheet 2, described damping sheet 2 simultaneously
Use flexible rubber damping plate.
Preferably, for improving decay resistance and the service life of backplate 6, described backplate 6 is galvanized sheet.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention；Skill for this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
