Embodiment
For fully understanding the purpose of this utility model, feature and effect, now by following specific embodiment, and cooperate accompanying drawing, the utility model is described in detail as follows:
As shown in Figure 1, a kind of vacuum refining furnace steam providing apparatus of the utility model comprises: flue type waste heat boiler 1, drum 2, thermophore 3, steam separator 4, the first vapor pressure variable valve group 12 and the second vapor pressure variable valve group 13.
Wherein, the flue type waste heat boiler 1 that is arranged on the converter furnace roof links to each other with drum 2 by the up pipeline 6 of steam/water circulating and the descending pipeline 7 of steam/water circulating respectively, forms thus a steam/water circulating loop.The steam outlet of drum 2 is connected with the drum steam outlet pipe 8 of straight-through thermophore 3 steam inlets.The steam outlet of thermophore 3 links to each other with steam-supply pipe 10 by thermophore steam outlet pipe 9 again, and the tie point both sides of thermophore steam outlet pipe 9 and steam-supply pipe 10 also are respectively equipped with the first vapor pressure variable valve group 12 and the second vapor pressure variable valve group 13 for steam regulation pressure.In addition, the two ends of steam-supply pipe 10 connect respectively external user U and steam separator 4.The steam outlet of steam separator 4 links to each other with the vacuum jet pump 5 of vacuum refining furnace by steam separator steam outlet pipe 11.
When the utility model was implemented, soft water entered in the drum 2 by softened water pump and enters flue type residual heat pot 1 through the descending pipeline 7 of steam/water circulating, by absorbing the steam that is converted to pressure 2.45MPa from the heat in the flue gas of converter.2.45MPa steam through the up pipeline 6 of steam/water circulating enter into drum 2 and within it section carry out carbonated drink separation, isolated water again enters flue type waste heat boiler by the descending pipeline 7 of steam/water circulating together with soft water and carries out above-mentioned circular treatment, repeats no more herein.The steam of 2.45MPa after carbonated drink is separated then enters thermophore 3 by the drum escape pipe 8 that is connected on the drum 2, and at this, thermophore 3 has the effect of storage, buffering flue type waste heat boiler 1 producing steam.Then, the steam of 2.45MPa enters steam-supply pipe 10 by thermophore steam outlet pipe 9, and the part in the above-mentioned steam makes vapor pressure become 0.8MPa, for other external user U by the adjusting of the first steam regulating valve group 12; The steam of another part 2.45MPa is the adjusting by the second vapor pressure variable valve group 13 then, makes vapor pressure become 1.0MPa, thereby and enters in the steam separator 4 and carry out improving carbonated drink separation steam quality in steam separator 4 inside.At last, these pressure are that the steam of 1.0MPa is delivered to the vacuum jet pump 5 of vacuum refining furnace by steam separator steam outlet pipe 11, for it.
