Description

A kind of combined type chemical industry burner

Technical field

The utility model is related to the combustion fields of chemical field pernicious gas more particularly to a kind of combined type chemical industry to burn Device.

Background technology

Chemical enterprise must be equipped with complete flare system, as safe auxiliary facility, for also wanting simultaneous in terms of environmental protection It cares for.Existing torch gas first passes around knockout drum after water sealed tank, and torch gas reaches in ground after reaching a constant pressure drop Face mix flare burner burns, and using the burner of water sealed tank back-fire relief, torch gas could be broken through after can only achieve a constant pressure drop Water seal enters burner combustion, just will appear emerging for one one discontinuity of flare in the case where pressure drop cannot continue, In continuous small-amount emission, burner energy sustained combustion near altar lamp forms apparent flame, but farther out from altar lamp Burner at can not form continuous flame, burning will be incomplete.

Utility model content

The purpose of this utility model is to provide one kind capable of completing the clean-burning combined type of different magnitude of torch gas Chemical industry burner.

To achieve the above object, the combined type chemical industry burner of the utility model, it is characterised in that：Including torch pipe network, Water sealed tank, spark arrester, annular burner, zero level burner and zero level torch pipeline, the water sealed tank outlet pass through torch pipe network It is connected to annular burner, described zero level torch pipeline one end is parallel-connected to torch pipe network, and the other end connects spark arrester, back-fire relief Device is connected to zero level burner by connecting line.

Further, the annular burner circularizes needle net distribution, and the zero level burner is arranged in annular firing The centre position of device.

Preferably, the torch pipeline between the water sealed tank and annular burner is divided into multistage pipeline.

Further, further include knockout drum and connecting line, the knockout drum outlet by connecting line with Water sealed tank connects.

Further, the present apparatus further includes altar lamp, and the altar lamp annular burner and zero level burner side are equipped with Altar lamp.

The combined type chemical industry burner of the utility model, mainly has the advantage that：

In the case of solving low pressure drop, torch gas can not break through water sealed tank, to cause burner combustion is insufficient to ask Topic；Ensure to keep burner to continue adequately to burn under various pressure drops.

Description of the drawings

Fig. 1 is the combined type chemical industry burner structure schematic diagram of the present apparatus.

Fig. 2 is the combined type chemical industry burner pipeline schematic diagram of the present apparatus.

Fig. 3 is the burner structure schematic diagram of the present apparatus.

In figure：1 is knockout drum, and 2 be water sealed tank, and 3 be zero level torch pipeline, and 4 be torch pipeline, and 5 be annular firing Device, 6 be zero level burner, and 7 be connecting line, and 8 be spark arrester, and 9 be gas pipeline.

Specific implementation mode

Such as Fig. 1, the combined type chemical industry burner of the utility model, mainly by torch pipe network, water sealed tank 2, spark arrester 8, ring Shape burner 5, zero level burner 6, zero level torch pipeline 43, knockout drum 1 and connecting line 7 form, annular burner 5 at Circular needle net distribution, zero level burner 6 are arranged in the centre position of annular burner 5.Annular burner 5 and zero level burner 6 sides are equipped with altar lamp, and altar lamp connects gas pipeline 9, fuel is provided for altar lamp.

1 entrance of torch gas piping connection knockout drum to be combusted, the outlet of knockout drum 1 connection 2 entrance of water sealed tank, water The outlet of sealed cans 2 is connected to annular burner 5 by multistage torch pipe network.

External zero level torch pipeline 43, zero level flare stack on connecting line 7 between knockout drum 1 and water sealed tank 2 The other end on road 43 is connected to 8 entrance of spark arrester, and the outlet of spark arrester 8 is connected to zero level burner 6.

In actual use, torch gas initially enters carries out gas-liquid separation to the present apparatus in knockout drum 1, isolate Liquid timing be discharged from knockout drum 1, the torch gas after separation by connecting line 7 enter water sealed tank 2, work as torch gas When pressure drop can not break through water sealed tank 2, torch gas enters 6 position of zero level burner by zero level torch pipeline 43, due to altar lamp It is arranged in 6 side of zero level burner, altar lamp flame is in right over zero level burner 6, the torch being discharged from zero level burner 6 Gas directly burns, and the gas for becoming harmless is discharged into air, is located at the spark arrester 8 of zero level combustion tube road to more than zero combustion tubes Road is protected, and will not be caused danger.

When torch air pressure drop can break through water sealed tank 2, torch gas enters multistage torch air pipe, and passes through annular firing Device 5, which is concentrated, to be discharged and burns.
