Description
Technical field:
The utility model relates to shock wave and blows the gray technology field, is specifically related to a kind of combustion gas-air mixed firing method and device with the shock wave soot blower.
Background technology:
Soot blower is one of indispensable important accessory of boiler of power plant, and its use whether suitable directly affects the safety and economic operation of boiler.The stove internal procedure is factors such as a kind of extremely complex physicochemical process, the structure of coal property, heating surface, temperature levels and air force operating mode, all affects the contamination and the slagging scorification of heating surface.So far, also shortage really can solve the theory and practice of dust deposit in furnace, slagging scorification.Therefore, only adjust and to solve dust deposit in furnace, slagging scorification problem often fully by boiler design and operation.
China's ature of coal aboundresources, the low ash smelting point ature of coal is more in the fuel used to generate power, and this has aggravated the contamination and the slagging scorification process of heating surface as the power fuel developing direction to use ash-rich, low heat value colm.Facts have proved, adopt the soot blower of sufficient amount, in boiler running process, often heating surface is purged, can prevent slagging scorification, dust stratification and the heated surface corrosion of boiler preferably, ensure safe operation of the boiler, improve the unit availability.Simultaneously, keeping clean conditions and effectively heat transfer, also can improve boiler efficiency and reduce the subsidiary engine power consumption, having remarkable economic efficiency because heating surface is in operation.
The shock wave soot blower is to utilize fuel gas (normally acetylene, natural gas, liquefied gas etc.) in special construction is mixed igniter, mix with air, lighted by high-energy igniter, produce detonation, detonation makes burning gases behind the flame front at the instantaneous high pressure that rises to, and before the sharp side of flame, form compressional wave, the flame compressional wave is constantly strengthened through gas conduct pipe the time, form stable shock wave one, this road shock wave enters the acceleration pulse generator and ignites the interior combustion mixture of tank body, and detonation gas is subjected to the modulation moment generation shock wave of special construction in the tank body.When shock wave acts on the dust stratification surface, its acoustic energy and kinetic energy will produce grey particle and impact and acceleraton disturbance, make it to separate with generating surface, thereby come off.By to the matched proportion density of two kinds of gases with hold the shock wave that control of energy generates multi-form and varying strength, can finish in various degree, the removing of dissimilar dust stratifications.
Shock wave blows at home existing extensive application of ash, and application is from early stage coal-powder boiler, the fluid bed furnace development that is mainly used in kilns such as oil, petrochemical industry, cement, metallurgy, oil oven, waste-heat oven to power industry.Along with the increasing of the capacity of boiler, the quantity of apply pulse soot blower increases greatly, and system is huge.The paired pulses soot blower has proposed higher specification requirement.
Existing shock wave soot blower is earlier combustible gas to be mixed with air mostly, by distribution circuit gaseous mixture is transported in each surge generator then, because the easy detonation of gaseous mixture, the pipeline of gaseous mixture is long and complicated in addition, and the security of this system is relatively poor.And mixing chamber and igniting chamber are separately, increased the volume of soot blower, make produce complicated.
Summary of the invention:
The purpose of this utility model is: a kind of combustible gas-air mixed method that shock wave blows ash that is used for is provided, make that combustible gas-air mixes, the ignition tip carbon deposit is light, help soot blower intensification, miniaturization, effectively reduce the temperature of mixing chamber, increase the security of soot blower system.
Above-mentioned purpose realizes by following technical scheme:
Three chamber mixing point cupping jar comprise cylindrical shell 2, cylindrical shell 2 both sides are equipped with air inlet pipe 4 and escape pipe 1 respectively, be provided with central dividing plate 1 and central dividing plate 26 in the cylindrical shell 2 cylindrical shell 2 is separated into mixing chamber 12, compartment 11 and igniting chamber 10, air inlet pipe 4 is opened aperture respectively in mixing chamber 12 and igniting chamber 10, air inlet pipe 4 distolateral in igniting chamber 10 by closure plate 9 sealing, igniting chamber 10 sides have ignition tip 3, and mixing chamber 12 sides have gas inlet pipe 7 and blowdown mouth 8.
Three above-mentioned chamber mixing point cupping jar, described cylindrical shell 2 both sides are equipped with air inlet pipe 4 and escape pipe 1 respectively.
Three above-mentioned chamber mixing point cupping jar are provided with central dividing plate 1 and central dividing plate 26 cylindrical shell 2 are separated into mixing chamber 12, compartment 11 and igniting chamber 10 in the described cylindrical shell 2.
Three above-mentioned chamber mixing point cupping jar, described air inlet pipe 4 is opened aperture respectively in mixing chamber 12 and igniting chamber 10, air inlet pipe 4 distolateral by closure plate 9 sealing in igniting chamber 10.
Three above-mentioned chamber mixing point cupping jar, described igniting chamber 10 sides have ignition tip 3, and mixing chamber 12 sides have gas inlet pipe 7 and blowdown mouth 8.
The beneficial effects of the utility model:
1. mixture homogeneity is better than prior art, evidence, and the mixture homogeneity of this mixed method and device compared with the prior art tool is greatly improved.
2. this is because mixture homogeneity improves, and the carbon distribution of the ignition tip of shock wave soot blower alleviates, and long service life is safeguarded simpler.
3. because degree of mixing improves, under the constant prerequisite of other condition, more save combustible gas, the bursting strength of gaseous mixture is also higher.
4. because mixing chamber and igniting chamber are integrated on the cylindrical shell, this miniaturization for the mixed firing part of shock wave soot blower, intensification design have crucial meaning.
5. owing to increase by a compartment in the middle of mixing chamber and the igniting chamber, the temperature of so effective reduction mixing chamber makes soot blower system more safe and reliable.
