Description
Technical Field
The invention relates to a soot blower in the technical field of boiler soot blowing, in particular to a long-nozzle shock wave soot blower which can prevent dust-containing smoke from entering a long-nozzle, a conveying pipeline and a shock wave generator and has the functions of cooling and preventing dust accumulation.
Background
Various industrial boilers are widely applied in the fields of energy and environmental protection, such as pulverized coal boilers, circulating fluidized bed boilers, waste heat furnaces, process furnaces, biomass boilers, garbage incinerators and the like. In the running process of the boilers, dust accumulation is generally easy to occur on the heated surfaces of convection tube bundles, so that the resistance of smoke is increased, the temperature of the smoke discharged is increased, the thermal efficiency of the boilers is reduced, and the normal running of the boilers is seriously influenced.
The shock wave ash blower, also called as gas pulse ash blower, uses common combustible gas such as acetylene (gas, natural gas, liquefied gas) and air, and after passing through respective flow measuring and controlling systems, they are uniformly mixed according to a certain proportion, and then fed into combustion chamber to burn. Unlike conventional combustion process and mode, the pulse combustion of fuel gas produces compression wave in high turbulence state with unstable combustion gas to form kinetic energy, sound energy and heat energy. The combustion speed is high, the gas pressure generated by combustion is limited within a certain range, and the impact wave energy emitted at the nozzle of the output pipe is adapted to the ash accumulation condition. The deposited dust on the heated surface is removed by the action of the shock wave, and dust particles, loose objects, adhesion objects and sediments on the polluted heated surface are removed.
The traditional shock wave soot blower jet pipe is a short jet pipe, generally, only a single jet pipe is arranged, the soot deposition area is covered by means of cutting and direction adjustment of the jet pipe, and because the high-speed jet flow generated by the shock wave soot blower is conical, the corresponding coverage area of the single jet pipe is limited, the energy of the area close to the jet pipe is high, the energy of the area far from the jet pipe is low, the soot blowing effect is reduced at the position far from the jet pipe, and a certain soot blowing dead angle exists.
In addition, because the shock wave soot blower is operated intermittently, when the shock wave soot blower stops working, the flue gas containing dust can enter the long spray pipe and the shock wave generator, a certain amount of plate accumulated dust can be generated in the long spray pipe, the external conveying pipeline of the furnace and the shock wave generator, and when the accumulated dust is serious, a gas mixing pipeline, a mixer and the like can be blocked, so that the shock wave soot blower cannot work normally; meanwhile, because the flue gas contains water vapor, the conveying pipeline outside the furnace and the shock wave generator are in the atmosphere, dust-containing water-containing flue gas in the flue gas is condensed on the inner wall and forms accumulated water after being cooled by the environment, and because the flue gas also generally contains SO2 and SO3 which are very soluble in water, the accumulated water generally has stronger acidity and can seriously corrode the inner wall of the soot blower.
Particularly, when the spray pipe in the flue is not cooled in a high-temperature environment with the temperature of more than 500 ℃ for a long time, the service life of the spray pipe can be reduced even if the high-temperature resistant stainless steel material is selected. Especially in the atmosphere that the flue gas dust such as garbage incinerator, process boiler and exhaust-heat boiler contains corrosive elements, the deposition in the spray pipe pipeline can not be removed, and the high temperature environment can accelerate the high temperature corrosion of the spray pipe, thereby greatly shortening the service life.
Aiming at the ash deposition phenomenon in the shock wave soot blower, air is introduced to clean, but because the oxygen content in the air is high and the long-nozzle soot blowing needs more air, if the carbon content in the ash deposition is higher, the ash deposition can be ignited in a high-temperature environment, secondary combustion of the ash deposition occurs in a flue, secondary damage can be generated to a heat exchange tube bundle, and on the other hand, the air temperature is lower, particularly in winter in northern areas, the heat exchange of the convection heat exchange tube bundle can be directly influenced by introducing more air.
