Abstract
Provided is a low-frequency stage frequency adjustable spiral whistle type sound wave soot blower. Traditional sound wave soot blowers are divided into a siren type sound wave soot blower, a diaphragm type sound wave soot blower and a vibration cavity whistle type sound wave soot blower according to action mechanisms. The diaphragm type sound wave soot blower is short in service life and cannot change frequency, and variant acoustic conversion rate drop can occur easily when the diaphragm type sound wave soot blower is arranged at a place with high temperature. The low-frequency stage frequency adjustable spiral whistle type sound wave soot blower comprises a magnifying barrel (1), the magnifying barrel is connected with an energy distributing tank (3) in a mounting shell body (2), the energy distributing tank is connected with a solenoid valve (4), the energy distributing tank comprises a stator (5), twelve strip seam nozzles (6) are evenly distributed on the circumference of the inner wall of the stator, the magnifying barrel is in a barrel shape with an outer circle and an inner cone, a rotor (7) is arranged in the circle tangential direction of the inner cone of the magnifying barrel, the rotor is provided with two strip seam mouths (8) with a 180-degree relative rotating included angle, the rotor is connected with a motor (9), and a disk type labyrinth sealing ring (10) is mounted between the rotor and the motor. The low-frequency stage frequency adjustable spiral whistle type sound wave soot blower is used for clearing soot formation of a heat exchanger.
Description
technical field:
the present invention relates to a kind of low-frequency range Frequency Adjustable and revolve 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 dedusting effect preferably 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 lively power coalescence phenomenon at sound wave effect and becomes bulky grain, is taken away to reach by flue gas under air-flow and Action of Gravity Field and blows grey purpose.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 in the shelter back, 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.The diaphragm life-span of diaphragm type is short and can not frequency conversion, and resonant cavity whistle is high frequency sound wave, places the high temperature place and is prone to the modification sound wave conversion ratio utmost point and falls.
summary of the invention:
the objective of the invention 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 purpose 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, 12 bar seam spouts of described 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, the 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 the 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 the 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:
1. 12 bars of inwall circumference uniform distribution of the present invention stitch the stator of spout annular gas storage functions, 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 the stator interior orientation under drive motors drives, the high pressure draught tangent line enters the inner cone rotor, forms the high air pulse that revolves and changes into acoustic energy.Change the drive motors rotating speed by frequency conversion and obtain the sound wave that meets each operating mode frequency of impact, improved transformation efficiency.The present invention's instructions for use that can meet under adverse circumstances simple in structure.
2. when stator of the present invention overlaps with the rotor bar sealing, high pressure draught enters rotor at two bar sealings along tangent line, forms the high air pulse that revolves and enters square expansion from venthole 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, by changing the drive motors operating frequency, realizes the staged operation, meets different operating conditions.
3. a low-frequency range Frequency Adjustable that the present invention 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 present invention's instructions for use that can meet under adverse circumstances simple in structure.
