Description
Technical field
The utility model relates to boiler auxiliaries, is specially a kind of compressed air shock-wave ash blowing device that boiler heating surface blows ash that is used for.
Background technology
The safety and economic operation of boiler is vast boiler user's a target, and especially Industrial Boilers such as fire coal and fuel oil are in the process of burning, and water-cooling wall and superheater etc. is located to produce the serious ash that blows.And the result of dust stratification will cause the thermal efficiency of boiler to reduce, stop up exhaust gases passes, and cause that superheat steam temperature raises, thereby the safe operation of harm steam turbine, even may cause the water-cooling wall inequality of being heated to cause the disastrous effect of squib, and dust stratification is a kind of vicious circle phenomenon from aggravation in boiler combustion process.Obviously, if fouling phenomenon is not effectively handled, with the safety and economy operation of serious harm boiler.In order to remove the dust stratification of each heating surface, improve the heat transfer of boiler, improve boiler operating efficiency, select really can solve boiler coke, dust stratification, save energy and reduce the cost, keep the safety in production realizing, and the practical boiler sootblower of increasing economic efficiency, just our common focus.
For boiler, the coking of burner hearth burning water-cooling wall, high temperature superheater and reheater are hung burnt, and the back-end surfaces dust stratification is common inevitable phenomenon.When the water-cooling wall coking was serious, big slag makes that slag cooling bucket is fluffy firmly can't deslagging; When high temperature superheater and reheater coking are serious, can make that the flue gas vestibule blocks between the part heating surface; When the back-end surfaces dust stratification is serious, superheater, reheater, economizer, air preheater heat transfer efficiency are reduced, exhaust gas temperature raises, and boiler efficiency reduces; Heating surface coking, dust stratification also can cause the heating surface overtemperature, and the aggravation heated surface corrosion shortens the heating surface life-span, can influence the normal operation of boiler when serious, even have influence on the personnel's of patrolling and examining personal safety.Therefore, coking, dust stratification are difficult problems that exists in the boiler operatiopn, all are furnished with the soot blower of some when boiler design, and soot blower commonly used has steam-type soot blower, gas impulse shock-wave ash blowing device, acoustic wave ash ejector.
Wherein, the steam-type soot blower is traditional soot blower, and usage quantity is maximum at present, because structure and medium, add the influence of hot environment, the ash gun pipe easily take place bite, malfunctioning, leak phenomenon such as vapour, equipment failure rate is higher relatively, requires maintenance levels higher; Its weak point is: blow ash and expend steam, reduced flue gas dew point, increased boiler feedwater.Blow ash and can only remove the heating surface that is blown to, blowing ash has the dead angle.The yielding bite of long retractable soot blower telescopic section, steam blow hinders heating surface and causes booster, and maintenance is big, and physical dimension is big, takies bigger locus.
The operation principle of gas impulse shock-wave ash blowing device is to utilize air and fuel gas (as hydrogen, acetylene gas, coal gas, liquefied gas and natural gas etc.) to mix in the proper ratio, in a special container, mix, through high-frequency ignition, produce detonation, the huge acoustic energy that moment produces and a large amount of high temperature and high speed gas, form with shock wave is vibrated, is clashed into and wash away heated surface bundle, and its superficial dust is splashed, and takes away with flue gas.Its weak point is: blow ash and consume combustion gas, need the periodic replacement air feed equipment.It is mainly big to vertical wash surface effect to blow ash, and blowing ash has the dead angle.Because working media is a fuel gas, in case project organization is unreasonable, has certain potential safety hazard.
Acoustic wave ash ejector is with the compressed air high pitch high frequency sound wave that high pitch high frequency sounding whistle produces of flowing through, sound wave is propagated in flue or burner hearth, affect the soot particle synchronous vibration in the flue gas, add up under the effect repeatedly in acoustic vibration and fatigue, small soot particle is difficult near the dust stratification face, the dust destruction that is deposited on the heating surface is peeled off, thereby reach the purpose of deashing.Its weak point is: the acoustic energy finite energy of generation has influenced its scope of application.
