Abstract
Provided is an air distribution machine of a burner, comprising a first air swirler and a second air swirler, which are coaxial structures. The first air swirler is provided with a gap type beveled edge which has an inclination of 40-50 DEG and is distributed in two layers of an inner ring and an outer ring. The inner wall of the second air swirler is provided with a second air swirl vane having an inclination angle of 10-25 DEG. The air distribution machine of a burner is advantageous in that the outlet swirling flow degree of the first air and second air can be effectively reinforced; the mixing degree of combustion air and fuel can be improved, and burning speed is effectively increased; through enlarging flame diameter and shortening flame length, the air distribution machine can be well adapted to a furnace burning device.
Description
Technical field
The utility model relates to a kind of burner air register.
Background technology
The diameter of a traditional wind cyclone of air register is less, and does not have the secondary wind swirl vane, so its flame is carefully, long status.Horizontal and the diameter less vertical furnace chamber bad adaptability short to length, and the flame size that such burner hearth requires generally should be weak point, thick state.
The utility model content
Its purpose of the utility model just is to provide a kind of burner air register, can strengthen the outlet swirl strength of wind and secondary wind effectively, and improves the mixed degree of combustion air and fuel, has improved burning velocity effectively.Through increasing flame diameter, shortening the length of flame, make this air register have good adaptation to short burner hearth combustion apparatus.
The technical scheme that realizes above-mentioned purpose and take; Comprise the wind cyclone one time, also comprise the secondary wind cyclone, a described wind cyclone and secondary wind cyclone are coaxial configuration; It is 40 °～50 ° clearance type angle that a described wind cyclone is provided with gradient; And be interior ring, the two-layer distribution of outer shroud, described secondary wind cyclone inwall is provided with the secondary wind swirl vane, and the angle of inclination of secondary wind swirl vane is 10 °～25 °.
Compared with prior art, the beneficial effect of the utility model is,
Owing to adopted the structural design of wind cyclone and secondary wind cyclone, thereby can strengthen the outlet swirl strength of wind and secondary wind effectively, and the mixed degree of raising combustion air and fuel, burning velocity improved effectively.Through increasing flame diameter, shortening the length of flame, make this air register have good adaptation to short burner hearth combustion apparatus.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to detail.
Fig. 1 is this apparatus structure schematic front view.
Fig. 2 is this apparatus structure diagrammatic top view.
Fig. 3 is an A-A cutaway view among Fig. 1.
Fig. 4 is a B-B revolved sectional view among Fig. 1.
The specific embodiment
This device comprises wind cyclone 1 one time; Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, also comprise secondary wind cyclone 2, a described wind cyclone 1 is a coaxial configuration with secondary wind cyclone 2; It is 40 °～50 ° clearance type angle that a described wind cyclone 1 is provided with gradient; And be interior ring, the two-layer distribution of outer shroud, described secondary wind cyclone 2 inwalls are provided with the secondary wind swirl vane, and the angle of inclination of secondary wind swirl vane is 10 °～25 °.
A described wind cyclone 1 is interior, secondary wind cyclone 2 outside, the two is identical to the direction of rotation that combustion air produces; The two relative position in the axial direction can be regulated through being installed in the sliding rail 5 on the wind cyclone 1, and one time wind cyclone 1 is provided with a wind cyclone support 4 and connects sliding rail 5, and sliding rail 5 is located on the flame cover 3, and is as shown in Figure 2.
This device mainly is made up of wind cyclone 1, a secondary wind cyclone 2; After combustion air gets into air register by the air channel; Be divided into two parts by air register, a part gets into burning through a wind cyclone 1 and revolves mouth, is called wind one time; Another part gets into burning through secondary wind cyclone 2 and revolves mouth, is called secondary wind.
Having gradient on the wind cyclone is 40 °～50 ° clearance type angle, and is interior ring, the two-layer distribution of outer shroud.
Be provided with the secondary wind swirl vane at secondary wind cyclone inwall, the angle of inclination of blade can be selected between 10 °～25 °.
Wind cyclone and secondary wind cyclone are coaxial configuration, and a wind cyclone is interior, the secondary wind cyclone outside, the two is identical to the direction of rotation that combustion air produces; The two relative position in the axial direction can be regulated through being installed in the sliding rail on the wind cyclone.
The secondary wind swirl vane is provided with secondary wind swirl vane supporting plate, and one time wind cyclone 1 is provided with a wind cyclone support 4 and connects sliding rail 5, and sliding rail 5 is located on the flame cover 3.
1 air register architectural feature
This air register, its primary structure characteristic that is different from the other types air register is: the one, strengthened the diameter of air register shell, a wind cyclone; Two is that a wind cyclone air outlet is the two-layer distribution of inner and outer rings; The 3rd, be provided with the secondary wind swirl vane at the air register inwall.
2 operation principles
After combustion air gets into air register; After the swirl vane turn, form rotation wind entering burning and revolve mouth, one time the wind cyclone makes fuel (combustion gas or mist of oil) before burning, realize the mixing of higher degree; After the igniting; Through the invigoration effect of secondary wind cyclone, strengthened mixing of combustion air and fuel, combustion process accomplished rapidly.In addition, the negative pressuren zone of a wind cyclone exit formation makes the high-temperature flue gas continuous backflow, has guaranteed the continuous, stable of combustion flame.
3 functions
3.1 be applicable to 50 ℃ of kinematic viscosity 730mm of burning
2All kinds of fuel oils of/s (diesel oil, heavy oil) and other liquid fuels.
3.2 series of products adapt to fuel oil or gas burner that output area is generally 350kW～3500kW.
3.3 efficiency of combustion is not less than 99.3%, O in the flue gas
2≤4.0%, CO≤0.100%.
3.4 the eddy flow angle through wind cyclone of change, secondary wind cyclone can change flame size effectively.Have the burner of wind of this high strength, secondary wind cyclone, than general burner, its length of flame can shorten about 1/3.
Through the relative axial position of wind cyclone of sliding rail adjusting and secondary wind cyclone, can require to change the shape of flame according to actual furnace.
