Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
Fig. 1 and Fig. 2 are refer to, Fig. 1 is a kind of section view of the embodiment of soot blower provided by the utility model
Schematic diagram；Fig. 2 is A-A shown in Fig. 1 to sectional view；Fig. 3 is the left view of schematic diagram shown in Fig. 1.
In a kind of specific embodiment, the utility model provides a kind of high frequency sound wave soot blower for boiler,
Including resonance cap 1, center-pole 2, flow guiding disc 3 and air bell 4；The resonance cap 1 open at one end other end closing；The air bell
4 be the annular hollow structure of open at both ends, and one end is air inlet, and the other end is gas outlet；Have in the inlet port
Conduit connection 9, the conduit connection 9 carries internal thread 91；By the internal thread 91, airway tube and soot blower can be facilitated
It is attached, and sealing effectiveness can be improved.Described one end of center-pole 2 stretch into it is described resonance cap 1 in bottom surface and with it is described
The resonance inwall of cap 1 forms the ring resonance 5 around the center-pole 2, and the other end of the center-pole 2 stretches into the air bell
4 inside, and be fixedly connected with the flow guiding disc 3；Multiple pod apertures 31 are offered on the flow guiding disc 3 vertically, it is described to lead
Flow table 3 is fixedly connected with the inwall of air bell 4；Annulus 6 is formed between center-pole 2 and the air bell 4 inwall,
The annulus 6 is located at the outlet port of the air bell 4；The center-pole 2 and the air bell 4 and the water conservancy diversion
Annular mixing chamber 7 is formed between disk 3；The resonance cap 1, the center-pole 2, the flow guiding disc 3 and the air bell 4 are integrated
Molding structure, can be processed manufacture by the way of hot investment casting.
In order to preferably realize the installation of soot blower, the top of the blind end of the resonance cap 1 is provided with polygon projection 10,
Its side number can be four or five or six, preferably hexagon.So, can be when airway tube be installed, with spanner or other works
Tool blocks polygon projection, then pipeline is screwed into conduit connection 9.
The operation principle of soot blower：Compressed air or steam enter from the air inlet of air bell 4, enter ring through pod apertures 31
Shape mixing chamber 7, rapidly sprays after being pressurized after fully mixing by annulus 6, and the air-flow of ejection forms certain frequency on wedge 8
The turbulent flow of rate, the turbulent flow resonates with the air column formation in resonant cavity 5, produces the sound wave of high-frequency high voice and strong, the high sound strong sound wave
Spread from the end of resonant cavity 5 to space, the spherical sound wave with judder effect is formed, during the sound wave on boiler tubing
Dust stratification vibration, fatigue, fracture and come off, so as to reach the purpose of boiler ash removal.
In actual applications, in order to realize that air-flow forms resonance in resonant cavity 5, and stable high-frequency high voice and strong is produced
Sound wave, preferably to reach the effect that the dust stratification on boiler tubing is shaken to fall, the end of the opening end of the resonance cap 1 and institute
The distance between the end of the outlet port of air bell 4 L is stated for 5-40mm, apart from it is excessive or too small when, resonance effect is not
It is stable even to form resonance, meanwhile, apart from it is excessive when can be long due to the length of center-pole 2, the reduction of its bending strength influences
Service life.
In addition, in order to ensure the air-flow sprayed from the annulus 6 of air bell 4 has enough pressure and uniform journey
Degree, to realize that air-flow forms resonance in resonant cavity 5, and produces the sound wave of stable high-frequency high voice and strong, preferably to reach
Dust stratification on boiler tubing is shaken the effect fallen, the annulus 6 that the center-pole 2 is formed with the air bell 4 it is big
Small M is 0.5-6mm, and gap is excessive, and stream pressure can be caused not enough, it is impossible to form resonance；Gap is too small, then throughput is not enough,
Also resonance effect can be influenceed.
In order to ensure air-flow can form resonance, the inwall and the air-flow of the resonance cap 1 well in resonant cavity 5
The inwall of cover 4 is columnar structured and internal diameter is identical, and the two is coaxial line, and now, annulus 6 can be right against resonance
Chamber 5, the inwall that the air-flow sprayed from annulus 6 can abut directly on resonant cavity 5 is flowed into resonant cavity 5, so as to most
The formation vortex of limits, substantially increases the effect to form air-flow resonance, and then be conducive to dust removing effects.
The center-pole 2 has a taper surface 21, the taper surface 21 be located at the inside of the air bell 4 and with the air-flow
The annular mixing chamber 7 is formed between cover 4 and the flow guiding disc 3, the bevel angle α of the taper surface 21 is 20 ° -140 °.Obviously,
The taper surface 21 is the flaring along on the approach axis of air-flow, on the one hand, can be in annular mixing chamber 7 by the taper surface 21
The high pressure draught of mixing imports annulus 6, on the other hand, can be formed using the taper surface 21 with air bell 4, flow guiding disc 3
One annular mixing chamber 7, with mixed airflow.Bevel angle is too small, then occupying the annular space of mixing chamber 7 can increase, influence air-flow
Well mixed, bevel angle is excessive, then can cause the local thinner of center-pole 2, and then intensity is substantially reduced, and influences service life.
Because resonance cap 1 and air bell 4 are connected as a single entity by center-pole 2, and the connection of center-pole 2 and air bell 4
The periphery of flow guiding disc 3 is only leaned on, and air-flow has to flow to annulus 6 by flow guiding disc 3, so flow guiding disc 3 must be provided with
In through hole, a kind of specific embodiment, the flow guiding disc 3 is disc, the axis weight of its axis and the inwall of air bell 4
Close, the pod apertures 31 on the flow guiding disc 3 are evenly distributed setting, the pod apertures 31 are 8-16.Pod apertures 31 are got over
It is many, be more conducive to the air-flow entered in annular mixing chamber 7 to be well mixed, still, pod apertures more than 31, then can make flow guiding disc 3 with
Connection between air bell 4 is weaker, is easily broken off.
In addition, in order to preferably realize the air-flow formation resonance into resonant cavity 5, the diameter D of the resonance inwall of cap 1
The diameter d ratio for the part stretched into the center-pole 2 in the resonance cap 1 is：D：d=1:0.3-0.6, the resonant cavity
5 bottom is arc surface, and arc radius R is with the diameter D ratio for resonating the inwall of cap 1：D：R=1:0.2-0.4 .
In summary, a kind of soot blower provided by the utility model, be formed in one structure, and rational in infrastructure, can
More stablized and more high frequency, the sound wave of high-strength sound, and then soot blowing effect is more preferably with the same conditions, being formed, meanwhile, this reality
Be easily installed and dismantled with new provided soot blower, in addition due also to structure reasonable and service life is greatly improved, fit
Significantly increased with property.
It is understood that embodiment of above be merely to illustrate that principle of the present utility model and use it is exemplary
Embodiment, but the utility model is not limited thereto.For those skilled in the art, this is not being departed from
In the case of the spirit and essence of utility model, various changes and modifications can be made therein, and these variations and modifications are also considered as this reality
With new protection domain.
