Abstract
The utility model provides a combustion-supporting air guide sheet for a gas spray gun, which is characterized in that on the basis of the existing oblique hole type wind guide channel, a circle of oblique slots are additionally evenly distributed on the periphery of the guide sheet; the oblique directions of the oblique slots and oblique holes are identical. With the adoption of the utility model, the flow quantity and the flow rate of the combustion-supporting air can be improved, and the spraying distance of the heat of flame can be prolonged thereby; the effect is much more obvious if the utility model is used in a wide-body kiln.
Description
It is the combustion air prerotation vane of the gas gun of fuel, particularly gas gun with the combustion gas that the utility model relates to a kind of.
Gas gun is the flame device of furnace equipment.Gas nozzle position at spray gun is provided with the combustion air prerotation vane, and this prerotation vane is to be located at one of nozzle periphery wall to enclose the flange that is the flange plate-like.Have a corral around the uniform inclined hole of nozzle centerline in flange, the inclined hole center line is tangential on a face of cylinder coaxial with nozzle centerline, and tilts along same circumferencial direction.Inclined hole runs through prerotation vane rear and front end face and forms air-guiding aisle.Combustion air forms one swirling eddy after air-guiding aisle blows out, not only play combustion-supporting effect, and blows to the destination for the heat with flame and to play an important role.Because existing prerotation vane has only a circle inclined hole, therefore bigger to the flow resistance of combustion air, the swirling eddy that forms a little less than, be difficult to flame heat regulating is blown to place far away, when in the expanded letter kiln, using especially, this shortcoming is particularly outstanding, often causes the burned product for the treatment of away from nozzle not become waste product because of reaching due temperature.
The purpose of this utility model provides a kind of combustion air prerotation vane that flame heat regulating can be blown to position far away.
For achieving the above object, the utility model includes a corral around the uniform inclined hole of nozzle centerline, and the inclined hole center line is tangential on a face of cylinder coaxial with nozzle centerline, and tilts along same circumferencial direction.Inclined hole runs through prerotation vane rear and front end face and forms air-guiding aisle.Especially, also be laid with a circle skewed slot at the prerotation vane periphery, skewed slot is identical with the incline direction of inclined hole.After the utility model prerotation vane has increased flume structure, greatly reduce the combustion air flow resistance, combustion air flow is strengthened, and because skewed slot is identical with the incline direction of inclined hole, therefore also strengthened the rotary speed of air-flow, thereby the heat of flame can be blowed to place far away, thereby reach the purpose of this utility model.
The utility model has the advantages that:,, still can provide enough temperature for it even therefore treat that burned product is far away from nozzle owing to increased the jet length of flame heat regulating.This advantage is particularly outstanding in the expanded letter kiln.
Below in conjunction with drawings and Examples the utility model is specified.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, combustion air prerotation vane 1 is the flange (delivery nozzle not shown in the figures) of flange plate-like for a circle that is located at the nozzle periphery wall, in flange, have a corral around the uniform inclined hole 3 of nozzle centerline 2, inclined hole center line 4 is tangential on a face of cylinder coaxial with nozzle centerline 2, and tilts along same circumferencial direction.Inclined hole 3 runs through prerotation vane 1 rear and front end face and forms air-guiding aisle.Also be laid with a circle skewed slot 5 at the prerotation vane periphery, skewed slot 5 is identical with the incline direction of inclined hole 3.Identical with prior art, in prerotation vane 1, also have two and be used for the wide peep hole 6 of examining flame, can not establish skewed slot in the position at peep hole 6 places.Combustion air forms one swirling eddy after skewed slot 5 blows out, it is identical that this swirling eddy and the swirling eddy that blows out through inclined hole 3 turn to, and strengthened the flow and the speed of swirling eddy, thereby the heat of flame can have been blowed to farther place.
