Abstract
An air distribution device for a burner comprises a primary air swirler and further comprises a secondary air swirler, wherein the primary air swirler and the secondary air swirler are of a coaxial structure, the primary air swirler is provided with slit type inclined openings with inclination of 40 degrees to 50 degrees, the inclined openings are distributed in a double-layer mode of an inner ring and an outer ring, an inner wall of the secondary air swirler is provided with secondary air rotational-flow blades, and the inclination angles of the secondary air rotational-flow blades range from 10 degrees to 25 degrees. Outlet rotational-flow intensities of primary air and secondary air can be effectively strengthened, the mixing degree of combustion-supporting air and fuel is improved, and the combustion speed is effectively improved. By increasing the diameter of flame and shortening the length of the flame, the air distribution device has good adaptability to a short-hearth combustion device.
Description
Technical field
The present invention 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.
Summary of the invention
Its purpose of the present invention 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, beneficial effect of the present invention 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 present invention is made further detailed description.
Fig. 1 is this apparatus structure schematic front view.
Fig. 2 is this apparatus structure diagrammatic top view.
Fig. 3 is A-A cutaway view and a B-B cutaway view among Fig. 1.
The specific embodiment
Comprise wind cyclone 1 one time; As shown in Figure 1, 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 secondary wind swirl vane 7, and the angle of inclination of secondary wind swirl vane 7 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.
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.
Secondary wind swirl vane 7 is provided with 6, wind cyclones 1 of secondary wind swirl vane supporting plate and 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.
