Beam is welded and fixed, and is poured again with furnace roof furnace wall with castable after acoustic wave ash ejector casing is cladded with one layer of ceramic fiber blanket, should
Acoustic wave ash ejector, which is selected, is resistant to 1000 DEG C of high-temperature alloy steels, and principle is：The acoustical generator of acoustic wave ash ejector be using compressed air as
Power source makes internal high intensity diaphragm generate low-frequency vibration and sends sound wave, then is amplified through public address cylinder, forms low frequency, height
It can sound wave.The high energy sound wave of specific frequency, which can be destroyed effectively, produced by it is deposited in the original packed structures of coil pipe dust, reaches
To the purpose of ash disposal.Its ash disposal mechanism is by the sound wave of high intensity, is sent into various possible dust stratification knots in running coil tubes
The area of space of slag by the effect of acoustic energy, makes the air in these regions generate vibration with dust particles, destroys and prevent
Combination of the powder dust particle between coil surface or particle is allowed to be in suspension fluidization state always, so that flue gas or gravity will
It is taken away.Fly ash content of the boiler of organic heat carrier of combusting coal water slurry in burner hearth is higher, and the flying dust in flue gas is easy to coalesce
The junction in gap between coil pipe wall surface, particularly two pipe of coil pipe.Sound wave is had an effect to being attached to coil surface area ash
Afterwards, because the vibration that acoustic wave energy generates shifts, big, speed is fast, causes flying dust dust that cannot gather, prevents the growth of cinder.Simultaneously
Due to the fatigue effect of high sound strong sound wave, its fracture can also be made to the bulk cinder formed, make the knot between cinder particle
Make a concerted effort to die down, gap increase, the speed of growth are slack-off, clinker volume reduces, be easy to voluntarily come off.The energy of sound wave is the frequency by it
Rate is determined with the sound intensity.The wavelength of low-frequency sound wave is compared with the length of high frequency sound wave, and the influence on the surface to being contacted is also big, therefore
The sound wave of the similary sound intensity, frequency is lower, bigger to the effect of dust.But if frequency is less than 60 hertz, sound wave will likely destroy
Solid structure and mechanical connecting device.The low-limit frequency of acoustic wave ash ejector selected by water-coal-slurry boiler of organic heat carrier is 75 hertz
Hereby, that is, preferable soot blowing effect has been reached and equipment is not caused to damage.
