Abstract

The invention provides a Venturi burner with shock absorption capacity. The Venturi burner comprises a Venturi pipe, a nozzle installing part and a supporting part for connecting the Venturi pipe with the nozzle installing part. The supporting part is of a sheet structure. The nozzle installing part and the Venturi pipe of the Venturi burner are connected through the sheet structure, and the flexibility of supporting is improved. Due to the fact that the equivalent diameter of the sheet bearing position is small, part of low-frequency shock can be absorbed, and the damping capacity is achieved. The burner can slightly swing in the normal direction of the sheet through supporting of the sheet structure, and when the overall structure of the burner is heated and deforms, a certain deformation allowance can be allowed through the sheet supporting structure.

Description

There is the venturi burner of damping capaicty
Technical field
The present invention relates to a kind of venturi burner, particularly a kind of venturi burner with damping capaicty.
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.Burner in combustion, because air-flow, air pressure change inside and outside torch are comparatively large, can cause the vibrations of burner.When vibrations are comparatively large, frequency is lower, may resonance be produced, and then cause the junction of support portion and Venturi tube or nozzle to rupture, cause great potential safety hazard.
Summary of the invention
In view of this, the present invention proposes a kind of venturi burner with damping capaicty.
Have a venturi burner for damping capaicty, comprise Venturi tube, nozzle mounting portion and connect the support portion of described Venturi tube and described nozzle mounting portion, described support portion is thin-slab structure.
In one embodiment, described thin-slab structure has uniform thickness.
In one embodiment, described support portion is curved thin-slab structure.
In one embodiment, described support portion is the thin-slab structure of ovalize.
In one embodiment, described support portion comprises the first connecting portion be connected with described nozzle mounting portion, the second connecting portion be connected with the bottom of described Venturi tube, and the gripper shoe be connected between described first connecting portion and the second connecting portion, the thickness of described gripper shoe is less than the thickness of described first connecting portion and the second connecting portion.
In sum, the invention provides a kind of venturi burner with damping capaicty.The nozzle mounting portion of venturi burner of the present invention is connected with adopting thin-slab structure between Venturi tube, increases the flexibility supported, because thin-plate supporting place equivalent diameter is less, can the vibrations of absorption portion lower frequency, and there is cushioning ability; Thin plate-shaped structure supports and makes burner can along thin plate normal direction slight oscillatory, and when burner overall structure be heated deform time, this thin plate supporting construction can allow certain deformation surplus.

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.
The invention provides a kind of venturi burner with damping capaicty, be connected by adopting thin-slab structure between Venturi tube with nozzle mounting portion, increase the flexibility that thin-slab structure supports, reduce the equivalent diameter of thin-slab structure supporting place, make venturi burner have certain damping capaicty.The invention provides following three kinds of thin-slab structures:
Fig. 1 is the perspective view of the venturi burner of one embodiment of the invention, and as shown in Figure 1, this venturi burner comprises Venturi tube 10, nozzle mounting portion 12 and connects the support portion 14 of Venturi tube 10 and nozzle mounting portion 12.
In an embodiment as illustrated in figure 2, support portion 14 employing is square and has the thin-slab structure of uniform thickness, and support portion 14 is integrated casting with Venturi tube 10 and nozzle mounting portion 12.
As shown in Figure 3, the support portion 14 in the present embodiment is the thin-slab structure with uniform thickness of ovalize, and support portion 14 is integrated casting with Venturi tube 10 and nozzle mounting portion 12.Certainly, support portion 14 also can be other arc.
As shown in Figure 4, support portion 14 comprises the first connecting portion 16 be connected with nozzle mounting portion 12, the second connecting portion 18 be connected with the bottom of Venturi tube 10, and the gripper shoe 20 be connected between the first connecting portion 16 and the second connecting portion 18, support portion 14 is integrated casting with Venturi tube 10 and nozzle mounting portion 12.Wherein, the thickness of gripper shoe 20 is less than the thickness of the first connecting portion 16 and the second connecting portion 18.
Above-mentionedly to be square, ovalize and the vibrations that two ends are thick, three kinds of thin-slab structures of intermediate thin all can reduce burner to a certain extent.Specifically, the thin-slab structure be square mainly utilizes the feature that its thin-slab structure is thin, adds the flexibility of support, and make the equivalent diameter at thin-plate supporting place less, the vibrations of absorption portion lower frequency, have cushioning ability; The thin-slab structure of ovalize is while having shock absorbing features, and the stress that the curved features of its thin plate also can reduce thin-slab structure is concentrated, and prevents thin-slab structure stress from too concentrating and rupturing; Two ends are thick, its middle thin-slab structure of the thin-slab structure of intermediate thin makes it have damping capaicty, and the thickness increasing two ends also makes the connection of support portion and Venturi tube and nozzle mounting portion be reinforced.
In sum, the invention provides a kind of venturi burner with damping capaicty.The nozzle mounting portion of venturi burner of the present invention is connected with adopting thin-slab structure between Venturi tube, increases the flexibility supported, because thin-plate supporting place equivalent diameter is less, can the vibrations of absorption portion lower frequency, and there is cushioning ability; Thin plate-shaped structure supports and makes burner can along thin plate normal direction slight oscillatory, and when burner overall structure be heated deform time, this thin plate supporting construction can allow certain deformation surplus.
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.
