Outlet side, the outlet side of airway 400 is connected with sound wave generation cap 500.It is apparent, of course, that the inlet end of airway 400 has
Air inlet 410, the outlet side of airway 400 has gas outlet 411.
Additionally, existing dust collection by sound wave device noise in dust removal process big main reason is that existing dust collection by sound wave
In the airway 400 of device there is inhomogeneities in the air pressure of air-flow, and then the frequency of sound wave resulted in is unstable, and then has
The shortcoming that noise is big, also causes its dust removing effects poor simultaneously.
Therefore, the loud non-maintaining soot blower system of intermediate frequency sound wave 100 in the present embodiment, arrange in the inside of airway 400
Having constant-current stabilizer 401 (as shown in Figure 2), the air pressure of this constant-current stabilizer 401 air-flow for transmitting from air inlet pipe 200 is uniform
Change, so that the frequency of sound wave is more stable produced by the uniform air-flow of air pressure, reduce the generation of noise, it is to avoid to surrounding band
Carry out harmful effect.
Concrete structure and work process to the constant-current stabilizer 401 of the present embodiment are further described below.
In the present embodiment, constant-current stabilizer 401 includes shunting disk 402 and diversion column 403 (as shown in Figure 2).Diversion column 403
One end be connected with shunting disk 402, the other end stretches out the gas outlet 411 of airway 400 and is connected with sound wave generation cap 500.Shunting
The outer circumference surface of dish 402 is connected with the inwall of airway 400.It is provided with multiple along shunting disk 402 circumferencial direction on shunting disk 402
Evenly distributed tap hole 404, tap hole 404 is in fan-shaped ((as shown in Figure 4)).
Preferably, in the present embodiment, the quantity of tap hole 404 is three, certainly, in other examples, and shunting
The quantity in hole 404 can be two or four or five etc..
Additionally, airway 400 includes the first locating sleeve 405 and the second locating sleeve 406.Second locating sleeve 406
Inwall is provided with the annular slot 407 for clamping shunting disk 402.The second positioning sleeve is stretched in one end of first locating sleeve 405
In pipe 406 and threaded with the second locating sleeve 406.The other end i.e. inlet port of the first locating sleeve 405, with air inlet pipe
200 connect.
When the first locating sleeve 405 is connected with the second locating sleeve 406, the right-hand member of the first locating sleeve 405 can push against
Shunting disk 402, shunting disk 402 is stable inside airway 400 firmly.
The wherein common shape in right part of the left part of shunting disk 402, the inwall of the first locating sleeve 405 and air inlet pipe 200
Become branch chamber 408.Air inlet 410 connects with branch chamber 408.The right part of shunting disk 402, the lateral wall of diversion column 403 and
The medial wall of two positioning sleeves is collectively forming current stabilization chamber 409.Gas outlet 411 connects with current stabilization chamber 409.Diversion column 403 and gas outlet
There is gap for airflow between the inwall of 411.
Air-flow in branch chamber 408 can effectively be shunted, due to air-flow by three in fan-shaped tap hole 404
Area of section reduces, and causes air pressure to increase, becomes evenly, then after being flowed in stable cavity, and then can converge that to form air pressure steady
Fixed uniform air-flow, and make the more stable property of frequency of the sound wave being subsequently formed, the noise of generation is little.
Wherein it is preferred to, in the present embodiment, the cross section in current stabilization chamber 409 is tapered, the area of section in current stabilization chamber 409 from
Shunting disk 402 tapers into toward the direction of gas outlet 411 so that when air-flow sprays from gas outlet 411, and the pressure of air-flow becomes big,
Add telling on of strong sound wave.
Additionally, specifically, in the present embodiment, sound wave generation cap 500 is provided with groove 501, the opening of groove 501 towards
Second locating sleeve 406.In diversion column 403 stretches into groove 501 away from one end of shunting disk 402 and with sound wave generation cap 500 even
Connect.Sound wave generation cap 500 is near forming resonator cavity 502 between the inwall and the outer wall of diversion column 403 of groove 501.
During work, the air-flow that air-stream generating device produces initially enters appendix 600, passes through air inlet pipe 200, then from
The air inlet 410 of air inlet pipe 200 enters in branch chamber 408.Air-flow in branch chamber 408 is in dividing on shunting disk 402
Discharge orifice 404, is divided into three strands of little airflows, converges then in current stabilization chamber 409, forms the air-flow of stable gas pressure.Air-flow is again
Spray from gas outlet 411, be close in the resonator cavity 502 that the outer wall of diversion column 403 enters into sound wave generation cap 500, with groove 501
Diapire collides, reverse reflux, produces resonance, forms sound wave.Under the effect of vibration of sound wave, in pyrolysis furnace inner components
Dust stratification come off by vibrations, reach the effect of soot blowing dedusting.
Preferably, in the present embodiment, sound wave generation cap 500 is the conical surface near the outer face of the second locating sleeve 406.
It is highly preferred that this conical surface and sound wave generation cap 500 angle α between the face of cylinder at the inwall place of groove 501
It it is 49 °～51 °.Further, in the present embodiment, the conical surface and sound wave generation cap 500 putting down near the inwall place of groove 501
Between face, angle α is 50.2 ° (as shown in Figure 3).
Sound wave generation cap 500 is collectively forming with the right-hand member end face of the second sleeve pipe near the outer face of the second locating sleeve 406
Acoustic wave reflector.Gap between sound wave generation cap 500 and the second locating sleeve 406 forms sound wave diffusion chamber, to the sound formed
Ripple is enlarged reflection, strengthens its vibrating effect.Using the sound wave generation cap 500 of cone structure, the effect of its reflection sound wave is more
By force so that the sound field of sound wave is strengthened, the effect of soot blowing dedusting has more advantage.
It should be noted that the pipeline configuration being arranged on the appendix 600 outside pyrolysis furnace can set with practical situation
Meter.The most in the present embodiment, appendix 600 includes elbow the 601, first seamless steel pipe 602, reduced tee 603 and uses
In the second seamless steel pipe 604 being connected with air-stream generating device.One end of elbow 601 is connected with air inlet pipe 200, the other end and
