Description
technical field:
the present invention relates to a kind of low-frequency stage frequency adjustable spiral whistle type sound wave soot blower.
background technology:
current acoustic wave ash ejector is widely used in field of heat exchangers (as industries such as power station, petrochemical industry, metallurgy), and heat exchanger surface dust stratification incrustation can reduce the thermal efficiency and utilization rate, the safe operation of entail dangers to equipment when dust stratification is serious.
acoustic wave ash ejector has obtained good dedusting effect in every profession and trade.High-power sound wave is sent in heat exchanger, the sound field forming stronger sound pressure level affects the soot particle synchronous resonant in flue gas, and the longitudinal pressure gradient dust stratification layer of periodically-varied dust stratification layer is by tired under alternately tension and compression effect and peel off, small soot particle issues raw power condensation phenomenon at sound wave effect and becomes bulky grain, is taken away to reach blow grey object under air-flow and Action of Gravity Field by flue gas.Low-frequency sound wave is had mercy on penetrating property and the higher heat exchanger saliency superiority of diffractive volumetric ratio fortunately, lessly after shelter occurs dead band, and heat exchanger does not produce wearing and tearing, washes away and corrodes the life cycle extending heat exchanger.
traditional sonic soot blowing equipment is divided into siren formula, diaphragm type and resonant cavity whistle three major types substantially by mechanism.The diaphragm life-span of diaphragm type is short and can not frequency conversion, and resonant cavity whistle is high frequency sound wave, places high temperature place and easily occurs that modification sound wave conversion ratio pole falls.
summary of the invention:
the object of the invention is, for overcoming the low shortcoming of siren acoustic wave ash ejector conversion ratio, to provide a kind of low-frequency stage frequency adjustable spiral whistle type sound wave soot blower of efficient conversion ratio.
above-mentioned object is realized by following technical scheme:
a kind of low-frequency stage frequency adjustable spiral whistle type sound wave soot blower, its composition comprises: expand and put cylinder, described expansion is put cylinder and is connected with the energy distribution tank in holder housing, described energy distribution tank is connected with magnetic valve, described energy distribution tank comprises stator, described stator inner wall circumference uniform distribution 12 bar seam spouts, it is cylindrical inner cone tubular that cylinder is put in described expansion, described expansion is put an inner cone circle tangential direction and is had rotor, described rotor arrangements has two relatively to rotate angle 180 ° of bar sealings, described rotor is connected with motor, disc type labyrinth seal ring is installed between described rotor and described motor.
described low-frequency stage frequency adjustable spiral whistle type sound wave soot blower, cover on cylinder is put in described expansion revetment bushing pipe, airtight and watertight padding is filled with in described revetment, described low-frequency stage frequency adjustable spiral whistle type sound wave soot blower, described drive motors is provided with terminal block base plate, described terminal block base plate is connected with terminal block.
described low-frequency stage frequency adjustable spiral whistle type sound wave soot blower, the bar seam spout of described stator is that circumference 12 parts is uniform, and the centerline hole of described stator is perpendicular to axis, and described stator two ends are semicircle.
beneficial effect:
1. the stator of inwall circumference uniform distribution of the present invention 12 bar seam spout annular gas storage functions, cylindrical inner cone tubular also arranges two rotors (as whistle) relatively rotating angle 180 ° of bar sealings along inner cone circle tangential direction, rotor rotates at stator interior orientation under drive motors drives, high pressure draught tangent line enters inner cone rotor, forms the high air pulse that revolves and changes into acoustic energy.Change drive motors rotating speed by frequency conversion and obtain the sound wave meeting each operating mode frequency of impact, improve transformation efficiency.Structure of the present invention simply can meet the instructions for use under adverse circumstances.
2. when stator of the present invention overlaps with rotor bar sealing, high pressure draught tangentially enters rotor at two bar sealings, formed high revolve air pulse from venthole enter square expansion put cylinder formed longitudinal sound wave.When stator and rotor stagger, air-flow is cut off square expansion to put cylinder is atmospheric pressure state.Rotor rotates a circle the pulse of generation ten secondary high-pressure, can obtain 24-550 hertz low frequency impact frequency according to motor speed, realizing staged and runs, carrying out satisfied different operating condition by changing drive motors operating frequency.
3. the present invention is applied to a low-frequency stage frequency adjustable spiral whistle type sound wave soot blower removing heat exchanger dust stratification and power condensation effect.Square expansion is put cylinder and is adopted the form of elongating transition region to obtain many air-flows of panting, and improve conversion ratio further and promote acoustical power, structure of the present invention simply can meet the instructions for use under adverse circumstances.
