Description
Technical field
The utility model relates to blower field, specially a kind of novel power plant fans.
Background technique
The harm of noise on human body be it is systemic, can both cause the variation of auditory system, can also be to non-sense of hearing system
System has an impact.These early stages influenced are mainly that physiology sexually revises, and Long Term Contact can cause pathology than stronger noise
It sexually revises.In addition, the noise in Work places may also interfere with communication, working efficiency is influenced, or even cause contingency.
Currently, the noise that Fan for Boiler in Power Plant main body and air duct vibration generate has influenced the life and work of power plant's surrounding resident, electricity
The improvement of factory's noise of boiler fan is extremely urgent.
Blower has irreplaceable status in power plant, in many years in use, some problems also display therewith.
Power plant fans some is in boiler ash discharge outlet, is easy the floating ash of accumulation, and longtime running will lead to floating ash, and but product is more, is attached to leaf
Piece surface, not only makes leaf quality unbalanced, also will affect blade and normally radiates, and increase blade surface temperature, the two
Superposition will lead to the hot dynamic balancing of blower and be affected, the working efficiency of blower reduces.The dust generated around blower,
Special messenger is needed to clear up, if floating ash can be accumulated in blower surface and inside, prolonged dust product without handling in time
It is tired, not only service life of fan can be caused to cut down, can also cause security risk to production environment.Power plant fans are in use process
In due to wind speed, assembling it is unstable, also or fanman make it is of long duration, pedestal loosen situations such as all blower can be made to transport
Generate a large amount of noise in row, not only have damage to blower components, to operator health there is also harm.
Application No. is CN201320433823.4, a kind of power plant's wind is disclosed in the patent that publication date is 2014.02.19
Machine pipeline damps compound sound absorption device, including damping composite sound-absorbing acoustic board and Fan pipeline；It is characterized in that the damping is multiple
Closing Felt includes acoustical cotton, air chamber, main joist, damping sound-insulation board, metal sound insulation plate, false keel and mask color steel plate；
Wherein most inner side is acoustical cotton, and main joist supports fixed damping sound-insulation board, forms air between acoustical cotton and damping sound-insulation board
Chamber, metal sound insulation plate are fitted closely in outside damping sound-insulation board, acoustical cotton are filled between metal sound insulation plate and mask color steel plate, by pair
Spine support is fixed.The compound suction of the damping of the power plant fans ventilation shaft simple, with strong points, sound insulation effect every Lu's apparatus structure
It is excellent, it is easy for installation.Although this scheme can be very good noise reduction, but do not give solution party for the floating ash in wind
Case, and there is no design protection measure for being easy impaired blade yet, therefore, the program need to be improved.
