Description
Technical field
A kind of slag-blowing equipmemt is the utility model is related to, relates in particular to a kind of variable-frequency electric sonic soot blowing device.
Background technology
In boiler running process, due to viscous between the surface traction of grey particle, particle and between particle and stove inner tubal wall
Tie many effects such as power, molecular adhesion, electrostatic attraction and chemical affinity, the heat exchange at burner hearth and each position of flue
Dust deposition will be gradually formed on face.
Prior art never has good manner of cleaning up, prior art to the dust stratification of burner hearth and each portion faces of flue
There is no corresponding equipment to carry out deashing while being produced.
Utility model content
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of stable performance, is not required to
Source of the gas is aided in, realizes a kind of variable-frequency electric sonic soot blowing device of lossless deashing.
Technical scheme：To achieve the above object, a kind of variable-frequency electric sonic soot blowing device of the present utility model, including driving
Device, the resonant cavity for abutting drive device and the megaphone connected with resonant cavity.
Further, a kind of variable-frequency electric sonic soot blowing device, including housing, connect housing drive device, located at shell
Internal resonant cavity and the megaphone for being installed on housing lower section and being connected with resonant cavity；The drive device includes electronic
Machine, sounding head and piston.
As a kind of preferred kind of drive of the utility model drive device, the drive device also includes high gear group
And bent axle.The utility model is to drive crankshaft driving piston reciprocating by motor, produces strong low frequency high energy sound wave,
Sound wave is propagated to vibrate in stove to be resident, and affects the soot particle synchronous vibration in flue gas, and the longitudinal direction in periodically-varied dust stratification boundary layer
Barometric gradient, under acoustic vibration and tired repeated action, small soot particle is set to be difficult to close to dust stratification face or make to be deposited on object
Dust on surface is destroyed and peeled off, so as to reach the purpose of deashing.
Because body vibration is big, therefore to ensure the steadiness connected between each component.The motor passes through sealing
Flange is connected with housing, and the sounding head is located in resonant cavity with piston.
As a kind of embodiment of the present utility model, the device also includes bearing, and the bearing includes left and right two respectively
Side is installed on the lobus sinister plate and lobus dexter plate of housing lower surface, and the height of the lobus sinister plate and lobus dexter plate is not less than megaphone lower end
Vertical height apart from housing lower end.The fix bar of connection megaphone is provided between the lobus sinister plate and lobus dexter plate, for solid
Determine megaphone.
As another embodiment of the present utility model, the device also includes bearing, and the bearing includes being arranged on shell
The level board of body lower surface and the support for connecting level board, the level board are provided with the fix bar of connection megaphone, are used for
Fixed megaphone.
Main technical performance index of the present utility model is sound pressure level (dB) and nominal frequency (vibration frequency) Hz, and it sets
Low-frequency sound wave wavelength in 3.8m/s, frequency is easy to acoustic energy in 90Hz and passes ripple, and decay is slow, and wave pressure operating radius is big.In addition
Because the propagation of sound wave is by surrounding resonance cavity wall and the reflex of loudspeaker tube wall, it is very strong that sound wave constantly reflects oscillation energy generation
Standing wave dust back and forth promoted to kick up allow air-flow to take flue out of.
Beneficial effect：Sonic soot blowing device of the present utility model, can actively, promptly in the running of denitration unit
Deashing processing is carried out, it, which has abandoned traditional acoustic soot blower, needs high power air compressor, big volume air accumulator and pressure wave
The defects of dynamic, it will progressively substitute conventional sootblower, the remote supermembrane chip soot blower of powerful acoustical power and whistle formula soot blower；The device
Moved by high speed machine and produce 94Hz vibration frequencies, export stable sound intensity height, dust removing effects are very notable.
