Abstract
The invention relates to an acoustic soot blower with high frequency and sound intensity, belonging to boiler equipment technological area. The blower comprises resonance cavity cap, gas-ring cover and air duct. They are concentrically installed in turn. On the outside of resonance cavity cap integral ring for resonance cavity is set and the end of resonance cavity cap is turbulent flow ring. One supporting concentric bar is set on the center of resonance cavity cap and circular resonance cavity, whose bottom is arc-shaped, is formed by the roof of the bar and the inner of resonance cavity cap. The frontal end of the supporting concentric bar extends into the end of gas-ring cover and circular gap, air room and diversion hole are formed by the supporting concentric bar and the inside of gas-ring cover. The end of air duct extends into the other end of gas-ring cover. In the invention, there are no any rotary parts and no need to e maintained in industrial scene. Dried saturated steam or compressed air is used as the driving source for acoustic soot blower. The soot blower is set on the furnace wall of boiler or in the boiler so as to reach optimal soot-blowing performance.
Description
Technical field
The present invention relates to a kind of high-frequency high voice and strong sound wave blower, belong to the boiler plant technical field.
Background technology
On each heat exchanger surface in various boiler plants, (comprise station boiler and Industrial Boiler, coal-burning boiler and oil burning boiler) its burner hearth and the flue, dust stratification and slagging scorification phenomenon almost do not appear exceptionally, the long-pending knot of ash, slag has reduced the thermal efficiency of boiler, also can have influence on the safe operation of equipment such as boiler when serious, be forced to blowing out and carry out artificial coke cleaning slagging-off, thereby reduced the utilization rate and the service life of boiler, strengthened working strength of workers even personnel casualty accidents takes place.In the face of this is prevalent in hard nut to crack in the various boilers for a long time, developed multiple boiler sootblower both at home and abroad in succession.At the end of the sixties, Mats doctor Olsson of Sweden STAL-LAVAL company has initiated the technology of removing dust stratification in the boiler flue with sound wave, and obtain United States Patent (USP) in nineteen eighty-two end, be characterized in: (1) is with the energy of compressed air as sound wave, utilize the principle that produces resonance in the elastic metallic diaphragm self-oscillation resonant cavity, the compressed air potential energy converting and energy is become acoustic energy, send into flue, to reach the deashing purpose.(2) whole system can only be according to a certain fixing frequency work after design and installation is finished, and its operating frequency is between 300-600Hz, and sound pressure level is 125-140dB.(3) volume of sound wave generating device is bigger, is about (400-500) x (600-1000) mm.(4) effectively operation temperature area is about 150-450 ℃, only limits to use in the flue scope of the economizer rear portion of boiler.
Summary of the invention
The objective of the invention is to propose a kind of high-frequency high voice and strong sound wave blower, change the structure of existing acoustic wave ash ejector,, improve boiler efficiency to improve the ducted dedusting effect of boiler heat-exchanger, guarantee the safe operation of boiler, and reach the purpose of boiler energy-saving, consumption reduction.
The high-frequency high voice and strong sound wave blower that the present invention proposes comprises resonant cavity cap, air ring cover and wireway.The coaxial successively installation of resonant cavity cap, air ring cover and wireway.The outer wall of resonant cavity cap is provided with the resonant cavity collector ring, the end of resonant cavity cap is the turbulent flow ring, the angle α of the resonance wedge of turbulent flow ring end and turbulent flow ring outer wall extended line is 25 °～70 °, the center of resonant cavity cap is the same core bar of a support, support is with forming ring resonance between the root of core bar and the resonant cavity cap inwall, the bottom of resonant cavity is circular-arc, supports an end that stretches into the air ring cover with the leading section of core bar, with the inwall of air ring cover looping gap, air chamber and pod apertures successively.The other end of described air ring cover is inserted in the end of mozzle.
In the above-mentioned soot blower, resonant cavity cap inner diameter D with the ratio that supports concentric shank diameter d is: D: d=1: 0.3～0.6, and the ratio of the radius R of resonant cavity cap inner diameter D and resonant cavity bottom circular arc is: D: R=1: 0.2～0.4.
The high-frequency high voice and strong sound wave blower that the present invention proposes, no any rotatable parts in the structure, with dry saturation vapor or compressed air driving source of the gas as acoustic wave ash ejector, soot blower can be arranged on the furnace wall of boiler, in the stove, in the mode of only single or many acoustic wave ash ejectors, at different boilers, different boiler heat-exchanger dust stratification situations, take different designs, reach the best and blow grey effect.And producing contactless ash-removal effect, deashing does not stay the dead angle.This acoustic wave ash ejector is different from existing Sweden reed-type acoustic wave ash ejector, uses in industry spot and must safeguard hardly.
Description of drawings
Fig. 1 is the structural representation of high-frequency high voice and strong sound wave blower of the present invention.
Among Fig. 1, the 1st, ring resonance, the 2nd, turbulent flow ring, the 3rd, annulus gap, the 4th, air ring cover, the 5th, resonant cavity collector ring, the 6th, resonance wedge, the 7th, air chamber, the 8th, gas port, the 9th, wireway, the 10th, support same core bar, the 11st, sealing ring, the 12nd, the resonant cavity cap, D is a resonant cavity cap inner diameter, and R is the radius of resonant cavity bottom circular arc, and d supports concentric shank diameter.
The specific embodiment
The structural representation of the high-frequency high voice and strong soot blower that the present invention proposes comprises resonant cavity cap 12, air ring cover 4 and wireway 9 as shown in Figure 1.The coaxial successively installation of resonant cavity cap 12, air ring cover 4 and wireway 9.The outer wall of resonant cavity cap 12 is provided with resonant cavity collector ring 5, and the end of resonant cavity cap is a turbulent flow ring 2, and the resonance wedge 6 of the end of turbulent flow ring 2 is 25 °～70 ° with the angle α of turbulent flow ring outer wall extended line.The center of resonant cavity cap 12 is that a support is with core bar 10, support is with forming ring resonance 1 between the root of core bar 10 and the resonant cavity cap inwall, the bottom of resonant cavity 1 is circular-arc, support is stretched into an end of air ring cover 4 with the leading section of core bar 10, with the inwall of air ring cover 4 looping gap 3, air chamber 7 and pod apertures 8 successively.The other end of described air ring cover 4 is inserted in the end of mozzle 9.
In the above-mentioned soot blower, resonant cavity cap inner diameter D and the ratio that supports concentric shank diameter d can be D: d=1: 0.3～0.6, and the ratio of resonant cavity cap inner diameter D radius R of circular arc bottom resonant cavity can be D: R=1: 0.2～0.4.
Below in conjunction with accompanying drawing, introduce the operation principle of the acoustic wave ash ejector of the present invention's design in detail:
Compressed air or steam enter gas port 8 and air chamber 7 by wireway 9, by ejection rapidly after 3 superchargings of annulus gap, the air-flow of ejection forms the turbulent flow of certain frequency on wedge 6, air column in this turbulent flow and the resonant cavity 1 forms resonance, produce the sound wave of high-frequency high voice and strong, this high sound intensity sound wave spreads to the space from the end of resonant cavity, formation has the spherical sound wave of judder effect, the vibration of dust stratification during this sound wave on the boiler tubing, tired, fracture and come off, thus reach the purpose of boiler ash removal.Sealing ring 11 becomes to closely cooperate when making wireway 9 insert the air ring cover.
