Abstract
The utility model relates to a burner fire tube with fins. The burner fire tube comprises a fire tube body and the ring-shaped fins, wherein the ring-shaped fins are welded to the outer wall of the fire tube body, and the ring-shaped fins are straight-plate-type ring-shaped fins and/or corrugation-type ring-shaped fins. The burner fire tube is small in diameter so that heating efficiency can be improved effectively, the heat transfer area can be increased, a partial temperature difference between the wall of the fire tube and media can be reduced, effective heat flux density and heat exchange efficiency can be guaranteed, and the risk of high-temperature pyrolysis of the media can be reduced effectively.
Description
Technical field
The utility model relates to oil gas field equipment technical field, particularly relates to a kind of finned burner fire cylinder.
Background technology
In industrial production, especially in the on-the-spot unregulated power supply of oil gas field, only have under the condition of combustion gas or fuel oil, often need to use burner heat medium.On some lower-powered burners, fire cylinder diameter is less; And the heat decomposition temperature for the treatment of media lower (if ethylene glycol heat decomposition temperature is lower than 200 ℃), burner under working condition, the temperature higher (higher than 250 ℃) of the fire cylinder barrel being connected with burner.In order to improve heat transfer efficiency, increase heat transfer area, often adopt ripple fire barrel structure.This ripple fire barrel structure is formed by the hot pressing of concave-convex mold forcing press or special purpose machine tool roll extrusion by straight fire cylinder, along axial direction, fire cylinder surface presents lumpy shape, for the fire cylinder of minor diameter, ripple fire cylinder difficulty of processing is larger, and heat exchange efficiency is not high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of finned burner fire cylinder, for solving minor diameter fire cylinder and the larger problem of heated medium Pintsch process risk.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of finned burner fire cylinder, comprises fire cylinder body and be welded on the some circular ring type fins on fire cylinder body outer wall.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described circular ring type fin adopts straight-plate-type circular ring type fin.
Further, described circular ring type fin adopts corrugated circular ring type fin.
Further, described circular ring type fin adopts straight-plate-type circular ring type fin and corrugated circular ring type fin.
Further, described circular ring type fin is provided with otch.
Further, the spacing of adjacent circular ring type fin is any value between 50mm to 100mm.
Further, the height of described circular ring type fin is any value between 30mm to 80mm.
The beneficial effects of the utility model are: the burner fire cylinder that the utility model is minor diameter, can effectively improve the efficiency of heating surface, increase heat transfer area, reduce the local temperature difference between fiery barrel and medium, can guarantee effective heat flow density and heat exchange efficiency, and effectively reduce the risk of medium Pintsch process.
Accompanying drawing explanation
Fig. 1 is the structural representation of finned burner fire cylinder described in the utility model;
Fig. 2 is the partial enlarged drawing of A-A in the utility model Fig. 1, has illustrated part there is no the circular ring type fin of otch;
Fig. 3 is the partial enlarged drawing of A-A in the utility model Fig. 1, has illustrated the local circular ring type fin with otch.
In accompanying drawing, the list of parts of each label representative is as follows:
1, fire cylinder body, 2, circular ring type fin, 3, burner interface
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, the present embodiment has provided a kind of finned burner fire cylinder, comprises fire cylinder body 1 and is welded on the some circular ring type fins 2 on fire cylinder body outer wall, on fire cylinder body, is also provided with the burner interface 3 for install combustion device.
In the present embodiment, described circular ring type fin 2 can all adopt corrugated circular ring type fin, also can all adopt straight-plate-type circular ring type fin.In general, in the less demanding occasion of condition of work, straight-plate-type circular ring type fin is comparatively applicable.Therefore, also can, according to actual conditions, adopt straight-plate-type circular ring type fin and corrugated circular ring type fin simultaneously.
In order to guarantee heat flow density, or guarantee smoke pipe installation site, the annular of circular ring type fin 2 can be changed into the annular of otch, described circular ring type fin is provided with otch.As shown in Figures 2 and 3, Fig. 2 is not nicked circular ring type fin, and Fig. 3 is the local circular ring type fin with otch.
In order to meet, condition of work requires and the feature of minor diameter, and the spacing of adjacent circular ring type fin is preferably any value between 50mm to 100mm, and the height of circular ring type fin is preferably any value between 30mm to 80mm.
The ethylene glycol reboiler of take is example, band fin burner fire cylinder described in the present embodiment is arranged in ethylene glycol reboiler, fire cylinder size is Ф 325, the spacing of adjacent fins is 50mm, fin height is 30mm, thereby increased heat transfer area, reduced heat flow density, reduced the temperature of fiery barrel fin root.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
