Description
Technical field:
The utility model belongs to the boiler ash removal technical field, is specifically related to a kind of combustion gas, air mixed firing device that is used for the boiler ash removal device.
Background technology:
The boiler ash removal device is to utilize fuel gas 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.
Existing boiler ash removal device is earlier combustible gas and air only to be carried out mixed once 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 mixing device that is used for boiler ash removal is provided, make that combustible gas, air mix, anti-reverse shock wave, ignition tip carbon deposit are light, help soot blower intensification, miniaturization, increase the security of ash disposal system.
Above-mentioned purpose realizes by following technical scheme:
The mixed firing device that is used for the boiler ash removal device comprises gaseous mixture escape pipe 1, cylindrical shell 2, ignition tip 3, cylindrical shell 6, gas inlet pipe 8, air intake duct 9, closure plate 11 and blowdown mouth 13, one gaseous mixture air inlet pipe 4 is arranged in the cylindrical shell 2, be provided with orifice plate 7 in the cylindrical shell 6, cylindrical shell 2 links to each other by dividing plate 5 with cylindrical shell 6.
Above-mentioned a kind of mixed firing device that is used for the boiler ash removal device, one gaseous mixture air inlet pipe 4 is arranged in the described cylindrical shell 2, gaseous mixture air inlet pipe 4 is evenly distributed with aperture, and with closure plate 14 sealings, the gaseous mixture air inlet pipe communicates with cylindrical shell 6 by dividing plate 5 at inlet end gaseous mixture air inlet pipe 4 in the outlet side.
Above-mentioned a kind of mixed firing device that is used for the boiler ash removal device is provided with orifice plate 7 cylindrical shell 6 is separated into mixing chamber 1 and mixing chamber 2 12 in the described cylindrical shell 6, orifice plate 7 is opened aperture.
Above-mentioned a kind of mixed firing device that is used for the boiler ash removal device, described cylindrical shell 2 links to each other by dividing plate 5 with cylindrical shell 6.
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 boiler ash removal device 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 integrate by dividing plate, this miniaturization for the mixed firing part of boiler ash removal device, intensification design have crucial meaning.
5. effectively prevent the reverse impact ripple effect, the security that improves system.
