Abstract
A relaxation deflation and natural gas separately fired inflamer refers to a gas inflamer filled with carbinol for a reborner crown. The gas inflamer comprises a natural gas spray rod, a dynamic and static barrel-style air register sleeved at the periphery of the natural gas spray rod at the same axis and a burner brick. The lower end of the static barrel of the dynamic and static barrel-styled air register connects with the inner-wall of the upper section of the burner brick. Around the natural gas spray rod evenly distributes a plurality of relaxation deflation spray rods passing through the burner brick and extending at the lower end of the burner brick. The utility model separately introduces the relaxation deflation to the lower end of the burner brick through the relaxation deflation spray rods, thereby separating from the natural gas, which reduces the use amount of the natural gas by making the best of the burning heat of the relaxation deflation and also avoids the damage of the burning heat to the inflamer and the reborner crown. The gas inflamer in particular applies to the reborner which is filled with carbinol and produces relaxation deflation.
Description
Technical field
The utility model relates to the gas burner of a kind of methanol device reburner tipburn.
Background technology
Methanol device can produce the very high off-gas of a large amount of hydrogen contents in process of production, common way is this off-gas part sky to be put burn, and another part is incorporated in the gas inlet pipe of gas burner of existing methanol device reburner tipburn to mix altogether with natural gas and burns.The formation of the gas burner of existing reburner tipburn comprises natural gas spraying gun, constitute with the sound cartridge type air register and the burner block of the coaxial setting of natural gas spraying gun, wherein, the hypomere of natural gas spraying gun is arranged in the direct tube section of burner block, the quiet tube air outlet of sound cartridge type air register is docked at the burner block top, once provides excessive air to guarantee the abundant burning of nozzle end combustion gas by the air inlet between the sound tube to the direct tube section of burner block.It is because these two kinds of burning of gas property differences are big that the burner of this structure is directly sneaked into the shortcoming of burning altogether in the natural gas with off-gas, its burning velocity is fast, flame is short, cause on the one hand to conversion tube to add thermal effect bad, the concentrated combustion in burner block also easily causes the damage of burner itself and reburner furnace roof on the other hand.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, and a kind of length of flame that guarantees is provided, and avoids the off-gas of the concentrated combustion of combustion gas in burner block and natural gas to divide the burner that burns.
This off-gas and natural gas split combustion type burner, comprise natural gas spraying gun, coaxial sound cartridge type air register and the burner block that is set in the natural gas spraying gun periphery, wherein, the quiet tube of sound cartridge type air register terminates at the epimere inwall of burner block down, it is characterized in that also being evenly equipped with around the described natural gas spraying gun some off-gas spray guns, described off-gas spray gun passes burner block and stretches out lower end at burner block.Once provide excessive air by the air inlet between the sound tube to the direct tube section of burner block equally during work, both guaranteed the abundant burning of natural gas nozzle end natural gas, that is to say, in burner, has only natural gas in burning, thereby do not burn too fast and phenomenon that the flame that causes is short takes place, kept normal use; Meanwhile, the excessive air lower end of continuing to go downwards to burner block offers the off-gas burning and uses.Because the combustion zone of off-gas is arranged in the burner hearth under the burner, so the heat that its produces can not act on burner, guarantees that to save natural gas heat imitates the purpose of unlikely again damage burner and furnace roof thereby realized making full use of off-gas.
Compared with the aforementioned existing similar products, the utility model has the advantages that with off-gas through the off-gas spray gun be introduced separately into burner block the lower end and with the natural gas separately-fired, with when reducing the natural gas consumption, also avoided of the damage of this heat at the calory burning that has made full use of off-gas to burner and furnace roof; The excessive air capacity that infeeds also can make natural gas crossing equivalent low NOx (nitrogen oxide) combustion zone burning, reduces the generation of nitrogen oxide, helps environmental protection.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A view of Fig. 1
Fig. 3 is the B-B view of Fig. 1
The specific embodiment
Shown in Fig. 1～3, this off-gas comprises natural gas spraying gun 1 with the formation of natural gas split combustion type burner, coaxial sound cartridge type air register 5 and the burner block 3 that is set in natural gas spraying gun 1 periphery, wherein, the following epimere inwall that terminates at burner block 3 of the quiet tube 9 of sound cartridge type air register, also be evenly equipped with some off-gas spray guns 2 around described natural gas spraying gun 1, described off-gas spray gun 2 passes burner block 3 and stretches out lower end at burner block.8 is bellows among the figure, and 10 is airduct, and 11 is peep hole, and 12 is fire hole, and 18 is the governor motion of air register 5.Structural relation between above-mentioned each parts and air register 5, natural gas spraying gun 1 and the burner block 3 all can be continued to use prior art version.Also can remove bellows, directly this burner is installed in the reburner air channel and use.Off-gas spray gun 2 by being installed on the panel 15 and being distributed on four forms that constituted on four jiaos of the burner blocks, is introduced off-gas by being located at the outer chuck 6 of natural gas spraying gun to four off-gas spray guns in the present embodiment.What the governor motion 18 of air register 5 adopted in the present embodiment is a kind of gear type governor motion, and promptly governor motion 18 is by being installed in gear 13 on the moving tube 14, being installed in the gear shaft 16 on the panel 15 and being fixed on the gear shaft 16 and the travelling gear 4 that is meshed with gear 13 constitutes.
The all right following setting of described off-gas spray gun is promptly offered hole 19 on described burner block body, the off-gas spray gun is arranged in this hole.The benefit of doing like this be the off-gas spray gun with the burner block body between be separated with an annular space mutually, it is combustion-supporting by the nozzle end that annular space offers the off-gas spray gun also can to suck air when off-gas ejection burning, also can reduce the heating degree of off-gas spray gun simultaneously, help prolonging the service life of off-gas spray gun.
Claims (2)
1, a kind of off-gas and natural gas split combustion type burner, comprise natural gas spraying gun, coaxial sound cartridge type air register and the burner block that is set in the natural gas spraying gun periphery, wherein, the quiet tube of sound cartridge type air register terminates at the epimere inwall of burner block down, it is characterized in that also being evenly equipped with around the described natural gas spraying gun some off-gas spray guns, described off-gas spray gun passes burner block and stretches out lower end at burner block.
2, off-gas as claimed in claim 1 and natural gas split combustion type burner is characterized in that offering on the described burner block body porose, and described off-gas spray gun is arranged in this hole.
