Abstract
The invention discloses an injection type burner with a gas inlet protection device. The injection type burner with the gas inlet protection device comprises a venturi tube, a nozzle and a flame stabilizer, the venturi tube has a gas inlet end and a gas outlet end, the nozzle is arranged at the gas inlet end, and the flame stabilizer is arranged at the outlet end; the injection type burner further comprises a cover arranged on the outer wall surface of the venturi tube, and the cover covers the gas inlet end of the venturi tube.
Description
Technical field
The present invention relates to a kind of injection burner, more particularly to a kind of injection type burning with air inlet protection device
Device.
Background technology
In petrochemical equipment, that is discharged in the timely process for producing device of Venting and Flare Stack System energy is unnecessary, harmful, unbalanced
Waste gas, and the unqualified gas produced when test run, driving and parking can be processed, and the instantaneous a large amount of gases released during accident, it is ensured that
Device is normal, safe operation.Torch burning will keep the stability of flame, if there is the problem of fray-out of flame, will make largely to have
Poison, the gas for having burn into inflammable and explosive are excessive, diffusion, will not only cause casualties, and pollute environment, and serious meeting causes
Blast, fire.And, if fuel combustion incomplete combustion, inefficient combustion, it will produce a large amount of noxious emissions, such as
Carbon monoxide, nitrogen oxides etc..
The content of the invention
In view of this, the present invention proposes a kind of injection with air inlet protection device for solving at least one above mentioned problem
Formula burner.
The present invention provides a kind of injection burner with air inlet protection device, including Venturi tube, nozzle and steady flame
Device, the Venturi tube has inlet end and an outlet side, and the nozzle is located at the inlet end, the flame holder be located at it is described go out
Gas end, also including the covering being located in the Venturi tube outside wall surface, the covering covers the inlet end of the Venturi tube.
In one embodiment, it is described to cover in a ring.
In one embodiment, the Venturi tube is provided with contraction section, the covering and Venturi tube near the inlet end
Link position be located at the Venturi tube contraction section outside wall surface.
In one embodiment, it is described to cover along a curved surface to radially outward and extending downwardly, to form bowl structure.
In one embodiment, distance of the radial outer end farthest of the covering apart from Venturi tube axis is the text
More than 2 times of the inlet end radius of venturi.
In sum, the invention provides a kind of injection burner with air inlet protection device, it has and covers text
The covering of venturi inlet end.Cover for blocking the powdered combustion product formed after burner combustion, rainwater or other are different
Thing, prevent combustion product or rainwater etc. from inlet end inspiration Venturi tube, significantly reduced because ignite burn product reflux and
Burnt insufficient chance caused by suction rainwater.
Brief description of the drawings
Fig. 1 is the schematic perspective view of one embodiment of injection burner.
The sectional view of Fig. 2 Fig. 1.
Specific embodiment
Before describing the embodiments in more detail, it should be understood that the invention is not restricted to institute hereafter or in accompanying drawing in the application
The detailed construction or arrangement of elements of description.The present invention can be the embodiment that other manner is realized.Furthermore, it is to be understood that this paper institutes
The wording and term for using are solely for describing purposes, should not the explanation of being construed as limiting property.It is used herein " including ", "comprising",
The similar wording such as " having " is meant comprising items listed thereafter, its equivalent and other additional things.Particularly, description is worked as
When " certain element ", the quantity that the present invention does not limit the element is one, it is also possible to including multiple.
Such as Fig. 1 and Fig. 2, the injection burner with air inlet protection device includes Venturi tube 2, nozzle 4 and flame holder
6.The Venturi tube 2 has inlet end 8 and outlet side 10.Nozzle 4 is located at the inlet end 8, and the flame holder 6 is located at described
Outlet side 10.Burner also includes the covering 12 being located on the lower end outer wall face of Venturi tube 2.Cover 12 and cover Venturi tube 2
Inlet end 8, for blocking powdered combustion product, rainwater or other foreign matters for being formed after burner combustion, prevents combustion product
Or rainwater etc. is by from the inspiration Venturi tube 2 of inlet end 8.If combustion product or rainwater etc. are inhaled into Venturi tube, can cause
Mixing is uneven, and burning is insufficient even to extinguish, so that increase noxious gas emission, such as carbon monoxide or nitrogen oxides
Deng.Increase covering 12 simply and effectively to solve this problem in that.
Venturi tube 2 has contraction section 14.In the present embodiment, 12 are covered and is located at text with the link position of Venturi tube 2
The outside wall surface of the contraction section 14 of venturi 2.12 are covered along curved surface to radially outward and extending downwardly, to form bowl structure.Along bent
The design for facing out and extending downwardly so that combustion product is not easy to be deposited in covering 12, and rainwater can be smooth along curved surface
Glide, leave burner.
In an illustrated embodiment, the radial outer end farthest (i.e. bottom) of covering 12 is apart from the axis of Venturi tube 2
Distance be more than 2 times of the inlet end radius of Venturi tube 2.
In sum, the invention provides a kind of injection burner with air inlet protection device, it has and covers text
The covering of venturi inlet end.Cover for blocking the powdered combustion product formed after burner combustion, rainwater or other are different
Thing, prevent combustion product or rainwater etc. from inlet end inspiration Venturi tube, significantly reduced because ignite burn product reflux and
Burnt insufficient chance caused by suction rainwater.
Concepts described herein may be embodied to other forms in the case of without departing from its spirit and characteristic.It is disclosed
Specific embodiment should be considered as exemplary rather than restricted.Therefore, the scope of the present invention be by appended claim,
It is determined rather than these descriptions before basis.Any change in the letter and equivalency range of claim is all
The scope of these claims should be belonged to.
