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, particularly relate to a kind of injection burner with air take guard mechanism.
Background technology
In petrochemical equipment, unnecessary, harmful, the unbalanced waste gas discharged in the timely process for producing device of Venting and Flare Stack System energy, and the defective gas produced when can process test run, start-stop car, and a large amount of gases of instantaneous releasing during accident, assurance device is normal, safe operation.Torch burning will keep the stability of flame, if there is the problem of fray-out of flame, by making, gas that is poisonous, that have burn into inflammable and explosive is in a large number excessive, diffusion, and not only will cause casualties, contaminated environment, serious meeting causes blast, fire.Such as, and if fuel combustion incomplete combustion, inefficient burning, will produce a large amount of noxious emission, carbon monoxide, nitrogen oxide etc.
Summary of the invention
In view of this, the present invention proposes a kind of injection burner with air take guard mechanism solving at least one the problems referred to above.
The invention provides a kind of injection burner with air take guard mechanism; comprise Venturi tube, nozzle and flame holder; described Venturi tube has inlet end and outlet side; described nozzle is located at described inlet end; described flame holder is located at described outlet side; also comprise the covering be located in described Venturi tube outside wall surface, described covering covers the inlet end of described Venturi tube.
In one embodiment, described covering ringwise.
In one embodiment, described Venturi tube is provided with contraction section near described inlet end, and the link position of described covering and Venturi tube is positioned at the outside wall surface of described Venturi tube contraction section.
In one embodiment, described covering along a curved surface to radially outward and to downward-extension, to form bowl structure.
In one embodiment, the distance of the distance Venturi tube axis, radial outer end farthest of described covering is more than 2 times of the inlet end radius of described Venturi tube.
In sum, the invention provides a kind of injection burner with air take guard mechanism, it has the covering covering Venturi tube inlet end.Hide Powdered combustion product, rainwater or other foreign matter for being formed after blocking burner combustion, prevent combustion product or rainwater etc. by from inlet end inspiration Venturi tube, significantly reduce and to burn product reflux and the insufficient chance of the burning that sucks rainwater and cause because igniting.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of an embodiment of injection burner.
The sectional view of Fig. 2 Fig. 1.
Detailed description of the invention
Before describing the embodiments in more detail, it should be understood that and the invention is not restricted to detailed construction in the application hereafter or described in accompanying drawing or arrangement of elements.The present invention can be the embodiment that alternate manner realizes.And, should be appreciated that wording used herein and term are only used as to describe purposes, should being construed as limiting property not explain.Similar wording meant and comprised item listed thereafter, its equivalent and other additional things " comprising " used herein, " comprising ", " having " etc.Particularly, when describing " certain element ", the quantity that the present invention does not limit this element is one, also can comprise multiple.
As Fig. 1 and Fig. 2, the injection burner with air take guard mechanism comprises Venturi tube 2, nozzle 4 and flame holder 6.Described Venturi tube 2 has inlet end 8 and outlet side 10.Nozzle 4 is located at described inlet end 8, and described flame holder 6 is located at described outlet side 10.Burner also comprises the covering 12 be located on Venturi tube 2 lower end outer wall face.Hide 12 inlet ends 8 covering Venturi tube 2, for the Powdered combustion product, rainwater or other foreign matter that are formed after blocking burner combustion, prevent combustion product or rainwater etc. by from inlet end 8 inspiration Venturi tube 2.If combustion product or rainwater etc. are inhaled in Venturi tube, mixing can be caused uneven, burn insufficient or even extinguish, thus increasing noxious gas emission, such as carbon monoxide or nitrogen oxide etc.Increase covering 12 simple, efficiently solve this problem.
Venturi tube 2 has contraction section 14.In the present embodiment, covering 12 and the link position of Venturi tube 2 are positioned at the outside wall surface of Venturi tube 2 contraction section 14.Hide 12 along curved surface to radially outward and to downward-extension, to form bowl structure.Along curved surface outwards and to the design of downward-extension, make combustion product be not easy to be deposited in covering 12, and rainwater can glide smoothly, leaves burner along curved surface.
In an illustrated embodiment, the distance hiding distance Venturi tube 2 axis, radial outer end farthest (namely bottom) of 12 is more than 2 times of Venturi tube 2 inlet end radius.
In sum, the invention provides a kind of injection burner with air take guard mechanism, it has the covering covering Venturi tube inlet end.Hide Powdered combustion product, rainwater or other foreign matter for being formed after blocking burner combustion, prevent combustion product or rainwater etc. by from inlet end inspiration Venturi tube, significantly reduce and to burn product reflux and the insufficient chance of the burning that sucks rainwater and cause because igniting.
Concept described herein may be embodied to other form when not departing from its spirit and characteristic.Disclosed specific embodiment should be regarded as exemplary instead of restrictive.Therefore, scope of the present invention is by appended claim, instead of determines according to these descriptions before.Any change in the letter and equivalency range of claim all should belong to the scope of these claims.
