Traditional sound wave ash blowing devices are basically divided into vortex whistle type devices, membrane type devices and resonant cavity whistle type devices based on the mechanism. Membranes of the membrane type devices are short in service life and invariable in frequency, and the transforming sound wave conversion rate is very low when the devices are placed at the high-temperature positions. The low-frequency-band variable-frequency vortex whistle type sound wave ash blower comprises a magnifying barrel (1), wherein the magnifying barrel is connected with an energy distribution tank (3) installed in a casing (2), the energy distribution tank is connected with a magnetic valve (4) and comprises a stator (5), and twelve slot spouts (6) are evenly distributed on the circumference of the inner wall of the stator. The magnifying barrel is in a shape of outer-circle inner conical barrel and is provided with a rotor (7) in the tangential direction of an inner conical circle, two slots (8) with 180-degree rotation angles are formed in the rotor, the rotor is connected with a motor (9), and a disc type labyrinth sealing ring (10) is installed between the rotor and the motor. The low-frequency-band variable-frequency vortex whistle type sound wave ash blower is used for removing dust accumulated on a heat exchanger.
Description
technical field:
the utility model relates to a kind of low-frequency range Frequency Adjustable and revolves whistle formula acoustic wave ash ejector.
background technology:
acoustic wave ash ejector is widely used in field of heat exchangers (as industries such as power station, petrochemical industry, metallurgy) at present, 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 been obtained good dedusting effect in every profession and trade.High-power sound wave is sent in heat exchanger, the sound field that forms 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 subject to tired under alternately tension and compression effect and peels 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.Rich the penetrating property of low-frequency sound wave and the higher heat exchanger saliency superiority of diffractive volumetric ratio fortunately, the less dead band that occurs after shelter, heat exchanger does not produce wearing and tearing, washes away and corrodes the life cycle that extends heat exchanger.
traditional sonic soot blowing equipment is divided into siren formula, diaphragm type and resonant cavity whistle three major types substantially by mechanism.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 is prone to the modification sound wave conversion ratio utmost point and falls.
utility model content:
the purpose of this utility model is for overcoming the low shortcoming of siren acoustic wave ash ejector conversion ratio, provides a kind of low-frequency range Frequency Adjustable of efficient conversion ratio to revolve whistle formula acoustic wave ash ejector.
above-mentioned object realizes by following technical scheme:
a kind of low-frequency range Frequency Adjustable is revolved whistle formula acoustic wave ash ejector, 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 12 bar seam spouts of stator inner wall circumference uniform distribution, described expansion is put cylinder for cylindrical inner cone tubular, described expansion is put an inner cone circle tangential direction and is had rotor, described rotor arrangements has two 180 ° of bar sealings of rotation angle relatively, described rotor is connected with motor, between described rotor and described motor, disc type labyrinth seal ring is installed.
described low-frequency range Frequency Adjustable is revolved whistle formula acoustic wave ash ejector, and the upper cover of cylinder is put in described expansion revetment bushing pipe, in described revetment, is filled with airtight and watertight padding,
described low-frequency range Frequency Adjustable is revolved whistle formula acoustic wave ash ejector, and terminal row base plate is installed on described drive motors, and described terminal row base plate is connected with terminal row.
described low-frequency range Frequency Adjustable is revolved whistle formula acoustic wave ash ejector, and the bar seam spout of described stator is that 12 parts of circumference are uniform, and the centerline hole of described stator is perpendicular to axis, and described stator two ends are semicircle.
beneficial effect:
the stator of 12 bar seam spout annular gas storage functions of inwall circumference uniform distribution of the present utility model, cylindrical inner cone tubular is also arranged two rotors (as whistle) of 180 ° of bar sealings of rotation angle relatively 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.By frequency conversion, change drive motors rotating speed and obtain the sound wave that meets each operating mode frequency of impact, improved transformation efficiency.The utility model instructions for use that can meet under adverse circumstances simple in structure.
when stator of the present utility model overlaps with rotor bar sealing, high pressure draught enters rotor at two bar sealings along tangent line, forms the high air pulse that revolves and from venthole, enters square expansion and put cylinder and form a longitudinal sound wave.When stator and rotor stagger, air-flow is cut off square expansion and puts cylinder for atmospheric pressure state.Rotor produces ten secondary high-pressure pulses in one week, according to motor speed, can obtain 24-550 hertz low frequency frequency of impact, realizes staged move by change drive motors operating frequency, meets different operating conditions.
a low-frequency range Frequency Adjustable that the utility model is applied to remove heat exchanger dust stratification and power condensation effect is revolved whistle formula acoustic wave ash ejector.Square expansion is put cylinder and is adopted the form of elongating transition region to obtain many air-flows of panting, and further improves conversion ratio and promotes acoustical power, the utility model instructions for use that can meet under adverse circumstances simple in structure.
