Description
Technical field
The utility model coupling body acoustic wave ash ejector belongs to the heat energy technical field, be specially adapted to burning solid, liquid and gaseous fuel boiler heating surface blow ash.
Background technology
With the mode of burning, change the chemical energy of coal, oil, fuel gas the equipment of heat energy into, as boiler, heating furnace etc., dust stratification, slagging scorification are inevitable on heating surface.Because fouling of heating surface has increased the thermal resistance of conducting heat, and has not only reduced rate of energy, and has had influence on the safety and economic operation of equipment, therefore, removes the fouling of heating surface slagging scorification, is the hard nut to crack that the correlation engineering technical staff runs into always.Traditional soot blower has steam sootblower, compressed air soot-blowing device, hydraulic(-ash) sluicing device, steel ball ash handling equipment or the like.Though these soot blowers have played certain effect to removing fouling of heating surface, slagging scorification, but because the design feature of self, in use often there is mechanical breakdown, blows and decrease heating surface tube and consume a large amount of steam, maintenance cost is more high, in this case, novel acoustic wave soot blower has just arisen at the historic moment.
Compressed-air actuated potential energy is modulated into acoustic energy in the sound wave powder producer, and introduces the ash that blows of boiler heating surface, start from 20th century the seventies abroad.Early eighties, the acoustics brainstrust of China be creatively with the blow ash of applications of sound waves in boiler heating surface, and developed rapidly.According to incompletely statistics, national now existing company more than 100 or enterprise are at the acoustic wave ash ejector of research, manufacturing, applied in various forms.
Up to now, large coal-fired boiler employed acoustic wave ash ejector in thermal power plant has three kinds of mainstream products by the principle branch, i.e. diaphragm type, siren formula and resonance cavate acoustic wave ash ejector.Resonance cavate acoustic wave ash ejector results from after diaphragm type, the siren formula acoustic wave ash ejector, and the resonant cavity acoustic wave ash ejector is better than the diaphragm type soot blower on key property.
The diaphragm type soot blower utilizes compressed-air actuated energy to make the diaphragm sounding.The diaphragm audible frequency is higher, and fatiguability damages, and service life is shorter relatively, in servicely needs also to add that a kind of special oil lubricate and the cooling diaphragm, needs to change once oily in general four months.Oil circuit atomizing cooling system be easy to Louing by, therefore, maintenance workload is bigger, belongs to imported product again, standby redundancy import difficulty costs an arm and a leg, this can steady in a long-termly move the acoustic wave ash ejector that requires bring the big difficulty in school.
Siren formula acoustic wave ash ejector, its sound wave are to cross a septal pathways that rotates at a high speed by air communication to produce.Its defective is that the rotating machinery that is in operation exists the problem of operational reliability, often owing to the break down normal use of the equipment that influences of electric rotating machine.The machinery of rotation needs oil lubrication at a high speed, has increased the possibility of generation fault in service.In operation practice, these drawbacks of this product in various degree influence the acoustic wave ash ejector reliability of operation.
Resonance cavate acoustic wave ash ejector partly is made up of the leading part and the resonant cavity of sounding body.Compressed air at first enters the leading part of sounding body, and by the annular gap ejection, high velocity air inspires the sound wave with certain frequency and acoustic pressure at the taper seat angle place of resonant cavity.
