Abstract
The utility model belongs to the technical field of boiler soot removal, and particularly relates to a mixing fire retarding device for a boiler soot blower, which mainly comprises a cylinder (3), a blocking plate (6), a combustible gas inlet pipe (7), an air inlet pipe (8) and a mixing chamber (9). Besides, an orifice plate (5) and a fire retarding unit (4) are arranged inside the cylinder (3). The mixing fire retarding device has the advantages of high mixing evenness, timely fire retarding, light ignition nozzle carbon deposition, favor for intensification and miniaturization of the soot blower and effective prevention of reverse impact wave.
Description
Technical field:
The utility model belongs to the boiler ash removal technical field, is specifically related to a kind of device that is used for combustion gas, air mixing and the back-fire relief of 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 with combustible gas pipeline handicapping firearm mostly, and combustible gas mixes with air in spark arrester enters mixing chamber, and promptly mixing chamber and fire retardant device have separately increased the volume of soot blower, make production complicated.
Summary of the invention:
The purpose of this utility model is: a kind of combustible gas of boiler ash removal, device of air mixing back-fire relief of being used for is provided, make combustible gas, air mix, in time back-fire relief, ignition tip carbon deposit light, help soot blower intensification, miniaturization, effectively prevent the reverse impact ripple, increase the security of ash disposal system.
Above-mentioned purpose realizes by following technical scheme:
The mixing fire retardant device that is used for the boiler ash removal device comprises cylindrical shell 3, closure plate 6, combustible gas air inlet pipe 7, air intake duct 8, mixing chamber 9, is provided with orifice plate 5 in the cylindrical shell 3, is provided with back-fire relief unit 4 in the cylindrical shell 3.
Above-mentioned a kind of mixing fire retardant device that is used for the boiler ash removal device is provided with orifice plate 5 in the described cylindrical shell 3, and cylindrical shell 3 is separated into back-fire relief chamber 10 and mixing chamber 9, and orifice plate 5 is evenly distributed with aperture.
Above-mentioned a kind of mixing fire retardant device that is used for the boiler ash removal device is provided with back-fire relief unit 4 in the described cylindrical shell 3, and 4 both sides, back-fire relief unit are provided with baffle ring 12 and baffle ring 11.
Above-mentioned a kind of mixing fire retardant device that is used for the boiler ash removal device, described cylindrical shell 3 has flange 22 to link to each other with flange 1 in back-fire relief chamber 10 sides.
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. back-fire relief unit next-door neighbour mixing chamber makes back-fire relief more timely, makes ash disposal system safer.
5. back-fire relief unit, orifice plate and combustible gas air inlet pipe are furnished with aperture, also have the effect that prevents reverse impact.
6. because mixing chamber and back-fire relief chamber are integrated on the cylindrical shell, this miniaturization for the mixed firing part of boiler ash removal device, intensification design have crucial meaning.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
