Description
Technical field
The utility model relates to a kind of boiler soot blower for industry spot, particularly a kind of sonic soot blowing device for removing the dust stratification in boiler.
Background technology
In the process of boiler coal-ash burning, except a part of product slagging scorification is fallen from slag-drip opening discharge, all the other not clean-burning volatilization powder, carbon granules, ashes etc. enter heating surface with flue gas, and then on heating surface cool, absorption, adhesion, become long-pending burnt and dust stratification, thus make heating surface thermal resistance increase thermal efficiency decline.Because the thermal conductivity factor of black dirt is only 0.1163w/ (m2 DEG C), it is 1/600 of steel thermal conductivity factor.The heat energy of pot contained by inner flue gas of the stove can not absorb timely and effectively at heating surface, causes exhaust gas temperature to raise, and heat loss increases, and boiler efficiency declines, and undercapacity, whole generating set is difficult to running at full capacity, and the economy of operation greatly reduces.Therefore need to carry out periodic ash disposal work to boiler.
Current existing process for deashing adopts the method for artificial ash disposal mostly, not only waste time and energy and also cost higher, therefore, how to adopt a kind of method or the device dust stratification removed efficiently in boiler to become industry problem demanding prompt solution.
The information being disclosed in this utility model background technology part is only intended to deepen the understanding to general background technology of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art known in those skilled in the art.
Utility model content
For deficiency of the prior art, the utility model aims to provide a kind of sonic soot blowing device for removing the dust stratification in boiler, and it can remove the dust stratification in boiler efficiently.
In order to solve the problem, this kind, for removing the sonic soot blowing device of collecting ash, comprising: compressed air hose, control valve, sonic generator, acoustic conducting pipe, blowing pipe and sound receiver;
Control valve is arranged on the entrance side of compressed air hose, for controlling the opening and closing of compressed air hose, compressed air hose is communicated with the air inlet of sonic generator, the outlet of this sonic generator is communicated with blowing pipe via acoustic conducting pipe, the open communication that the furnace wall of blowing pipe and boiler side is offered, relative with this acoustic conducting pipe on the furnace wall that this sound receiver is arranged on boiler opposite side.
Preferably, described sonic generator is diaphragm type sonic generator or siren formula sonic generator; Described sound receiver is acoustic receiver or sound transducer.
Preferably, described blowing pipe has enlarging, the open communication that this enlarging and described boiler wall are offered.
Preferably, described compressed air hose is the pipe through bending at least one times.
Preferably, this sound receiver described is relative with acoustic conducting pipe along the circumference of boiler wall.
The beneficial effects of the utility model: this device is connected successively by compressed air hose, sonic generator, acoustic conducting pipe, blowing pipe, using the energy of compressed air as sound wave, be low frequency acoustic energy compressed air potential energy converting and energy, by air dielectric, acoustic energy is delivered to corresponding dust stratification point, reaches the effect of deashing.This apparatus structure is compact, easily be applied to industry spot this kind of device, blow grey scope wide, there is not dead band, dead angle, in addition acoustic receiver device receives acoustic signals and the mean temperature calculated on sound ray, also can obtain average temperature value in stove, and then Real-Time Monitoring can be carried out to pot in-furnace temperature easily, improve the overall utility of this device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sonic soot blowing device for removing collecting ash of the present utility model.
Detailed description of the invention
Shown in composition graphs 1, this kind is for removing the sonic soot blowing device of collecting ash, and it comprises: compressed air hose 1, control valve 2, sonic generator 3, acoustic conducting pipe 4, blowing pipe 5 and sound receiver 7.
This control valve 2 is arranged on the entrance side of compressed air hose 1, for controlling the opening and closing of compressed air hose, compressed air hose 1 is communicated with the air inlet of sonic generator 3, for the ease of being connected with air compressor and saving space, the profile of this compressed air hose can be configured to the pipe through bending to be formed L-type at least one times.The outlet of this sonic generator 3 is communicated with blowing pipe 5 via acoustic conducting pipe 4, and this sonic generator 3 can be diaphragm type sonic generator or siren formula sonic generator, in embodiment of the present utility model, is preferably diaphragm type sonic generator.The open communication that the furnace wall 6 of blowing pipe 5 and boiler side is offered, circumference on the furnace wall 6 that sound receiver 7 is arranged on boiler opposite side and along boiler wall is relative with this acoustic conducting pipe 5, the voice signal of reception is sent to processing unit (not shown) by this sound receiver, processing unit can calculate in boiler according to other parameters of this voice signal and boiler, be at least the average temperature value between sound phonation unit and sound reception unit, control operation further can be done to boiler according to this temperature value.This sound receiver 7 can be acoustic receiver or sound transducer, in embodiment of the present utility model, is preferably acoustic receiver.In addition, this blowing pipe 5 has expansion mouth, and the open communication that this expansion mouth and described boiler wall are offered, can amplify further to sound wave.
Along with control valve 2 is opened, air through overcompression enters sonic generator 3 by compressed air hose 1, there is dress device 3 by sound wave and send sound wave, sound wave is undertaken being amplified into blowing pipe 5 by acoustic conducting pipe 4, blowing pipe 5 is goed deep into boiler wall inside purge, utilize the Wave energy of sound wave on the one hand, make the deposit after boiler combustion produce displacement and leave origin-location, thus reach the object removing dust stratification and dredging; On the other hand, this sound wave, as signal source, is received by sound receiver, and calculates by transmitter unit to the temperature averages on receiving element path.
This temperature averages can by formula
draw:
In this formula, V represents the spread speed m/s of sound wave in gas medium;
γ represents the ratio of gas medium specific heat at constant pressure and specific heat at constant volume;
R represents gas constant 8.314J/ (molK);
T represents absolute temperature K;
M represents the molal weight kg/mol of gas.
Because gas composition composition is less on acoustic wave propagation velocity impact, under most of application conditions, the change of this component is also little, and therefore acoustic wave propagation velocity can regard the monotropic function of gas medium temperature as.Concerning acoustic thermometry technology, the distance of transmitter unit and receiving element can be measured, and is a constant.Therefore, only need to measure sound wave reflection method accurately, just can obtain average temperature value by above formula.
Above-described embodiment is for illustrative principle of the present utility model and effect thereof, but the utility model is not limited to above-mentioned embodiment.Those skilled in the art all without prejudice under spirit of the present utility model and category, in claims, can modify to above-described embodiment.Therefore protection domain of the present utility model, should cover as claims of the present utility model.
