Abstract
The invention discloses a safer and more reasonable waste heat furnace top air pipe structure which comprises a frame body and multiple air pipes which are arranged on the frame body at intervals. Multiple ventilation holes are formed in the side wall of each air pipe. Each air pipe communicates with multiple branch pipes which are formed in the manner that the corresponding ventilation holes extend towards the outer side. Each branch pipe comprises a main branch pipe body formed in the manner that the corresponding ventilation hole extends towards the outer side, a special-diameter branch pipe body arranged parallel to the main branch pipe, and a bend used for communicating with the main branch pipe body and the special-diameter branch pipe body. A first air outlet is formed in each main branch pipe body. By means of the safer and more reasonable waste heat furnace top air pipe structure, the number of the air outlets needing to be formed in the main branch pipe bodies can be reduced, the integral strength of the main branch pipe bodies is improved, so that it can be ensured that cold air flows in the whole branch pipes, the service life of the air pipes is prolonged, meanwhile, safety running of a furnace top can be protected more effectively, potential safety hazards are eliminated, and production accidents are reduced.

Background technology
In major part Nitrogenous Fertilizer Industry, majority can configure a heat recovery boiler, is mainly used in reclaiming synthesis ammonia and speeds to put
Gas and producing gas blower, be used for heat supply, generating etc. by the heat of recovery.
This kind of top, waste heat boiler combustion furnace great majority use air hose distribution, and Main Function has 2 points: 1, increase combustion
Burn oxygen content in stove, it is ensured that producing gas blower and synthesis ammonia relief gas can the most fully burn.2, protection furnace roof will not be because of
Local temperature is too high and burns out.
But current airduct arrangement existing defects, the arm end near both sides furnace wall is a dead angle, and the inside does not has
Having flow of cold air, so this section arm is easy for burning out, and time length arm has lacked the strong point and will send out owing to end burns out
Change shape, ultimately results in the uneven safe operation threatening furnace roof of furnace roof cooling air distribution.
Summary of the invention
The present invention provides a kind of safer rational waste-heat oven top air duct structure, and its main purpose is to overcome existing wind
What pipe arrangement existed be easily deformed, defect that service life is low.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of safer rational waste-heat oven top air duct structure, is spaced including support body and complex root and is arranged on this support body
Air hose, the sidewall of every air hose all offers a plurality of air vent, and described air hose is communicated with thereon by each ventilation
The complex root that hole extends laterally and formed is in charge of arm, described in be in charge of arm and include that one is extended laterally by air vent and formed
The reducing branch that is arranged side by side with this body manifold of body manifold and for connecting the curved of body manifold and reducing branch
Head, described body manifold offers one first gas outlet, described reducing branch be one by with the junction of described elbow towards
This direction, the first gas outlet extend tubular body, the end of this tubular body be provided with one with the described first adjacent cloth in gas outlet
The second gas outlet put.
Further, described first gas outlet is identical with the size of the second gas outlet.
Further, the diameter of described tubular body is identical with the diameter of described first gas outlet.
Further, described first gas outlet is arranged at the middle part of body manifold, its discharge directions and air inner air tube
Circulating direction parallel, the discharge directions of described second gas outlet is perpendicular with the circulating direction of air inner air tube.
Further, the diameter of described tubular body is less than the diameter of described supervisor's arm.
Further, it is in charge of arm described in each to be vertically connected on the sidewall of described air hose.
Further, the diameter diameter less than described air hose of arm it is in charge of described in each.
Further, described elbow is C-shaped elbow, and this C-shaped elbow includes that one is connected with the end of described body manifold
Inlet end, an outlet side being connected with described reducing branch and one by this inlet end, to outlet side, isometrical extension is formed
C-shaped portion.
Compared to the prior art, what the present invention produced has the beneficial effects that:
1, present configuration is simple, practical, is arranged to the form of reducing, elbow by being in charge of the end of arm, thus can
To reduce the gas outlet number needing to offer in body manifold, improve the bulk strength of body manifold, the most both can ensure that whole
There is flow of cold air in arm, increase airduct service life, also can more effectively protect furnace roof safe operation simultaneously, eliminate peace
Full hidden danger, reduces the generation of production accident.
2, in the present invention, the first gas outlet is different with the discharge directions of the second gas outlet and is capable of furnace roof
Each position angle falls to being aerated, it is possible to ensures that furnace roof cooling air distribution is uniform, effectively guards against the situation occurring that furnace roof burns.
