Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, the utility model comprises drum 3, drum upper hose 16, drum outfall sewer 8, water inlet pipe header 10, steam discharge pipe header 14 and annealing furnace quench zone 11, annealing furnace quench zone 11 comprises two sections of one section of annealing furnace chilling and chillings, wherein: one section of annealing furnace chilling and annealing furnace chilling evenly are provided with cooling tube 12 and cooling tube 13 for two sections, and cooling tube 12 is 20
89 * 4mm heat-resisting seamless steel pipe, cooling tube 13 is 20
108 * 4mm heat-resisting seamless steel pipe, the steel pipe between centers of cooling tube 12 is 180mm, the steel pipe between centers of 8 cooling tubes 13 is 260mm, the high end of steel pipe one end of cooling tube 12 and cooling tube 13 is low, the two ends height differs and is 300mm, a low end links to each other by water inlet pipe header 10 with drum outfall sewer 8, a high end links to each other by steam discharge pipe header 14 with drum upper hose 16, drum upper hose 16 is provided with wash water valve 9 and wash water valve 15 with drum outfall sewer 8 bottoms, drum 3 links to each other with water inlet pipe header 10 by drum outfall sewer 8, links to each other with steam discharge pipe header 14 by drum upper hose 16; Drum 3 has drum support 7 to support, and is provided with by the annealing furnace power house, and than annealing furnace quench zone cooling tube 12 and cooling tube 13 high 1～3m, high pressure soft water pipeline 1 is communicated with drum 3, thereby forms an airtight system.Drum is generally elected 2～5t as, pressure-bearing 10～16kgf/cm
2, soft water is from the soft water station, and caliber is
57 * 3mm comes waterpipe to pass through valve 2 and water meter control.The drum operating post is located near the drum, and steam water-level is taked triple monitoring, is respectively high-low water alarm, two-colour fluviograph, electric contact.
During normal the operation, high pressure soft water is delivered to drum 3 by pipeline 1, soft water is delivered to annealing furnace quench zone 11 cooling tubes 12 and cooling tube 13 by drum downtake 8 from drum 3 again, the vaporization of in annealing furnace quench zone 11 cooling tubes 12 and cooling tube 13, being heated of liquid water, heat is taken away, thereby played the purpose that annealing furnace quench zone chilling is lowered the temperature; Because the effect of pressure reduction, water vapor enters drum 3 from annealing furnace quench zone 11 cooling tubes 12 and cooling tube 13 1 ends through drum upcast 16, soft water in the drum 3 enters the other end of annealing furnace quench zone 11 cooling tubes 12 and cooling tube 13 naturally from drum downtake 16, thereby forms natural circulation; High pressure steam in the drum 3 is given cast tube health pond or other user through pipe-line transportation.
During design, consider when the high temperature steel masking shield all is vertical in the annealing furnace quench zone, cross the pipe amount after a little while, may cause temperature to descend too much, can rationally control the quench zone temperature by control high temperature steel masking shield flip angle.
When the cast tube annealing furnace is prepared to produce, open the valve 2 on the high pressure soft water pipeline 1, high pressure soft water is delivered to drum 3 from the soft water station, and soft water enters one section cooling tube 12 of annealing furnace chilling and two sections cooling tubes 13 of chilling by drum downtake 8, water inlet pipe header 10; When annealing furnace begins to produce, elevated temperature heat waste gas enters annealing furnace quench zone 11 from holding-zone, emit heat by the high temperature cast tube of annealing furnace quench zone 11 by thermal radiation simultaneously, soft water in one section cooling tube 12 of chilling and two sections cooling tubes 13 of chilling absorbs heat and produces high-temperature steam, because the effect of pressure reduction, high-temperature steam enters drum 3 by steam discharge pipe header 14, drum upcast 16, soft water in the drum 3 enters one section cooling tube 12 of annealing furnace chilling and two sections cooling tubes 13 of chilling by drum downtake 8, water inlet pipe header 10 simultaneously, thereby forms natural circulation.High pressure steam in the drum 3 is delivered to cast tube health pond or other user by steam delivery tube road 5 and induction valve 6 again.Drum 3 water levels are then observed by the high-low water alarm, electric contact and the two-colour fluviograph that are installed in watchroom and are judged, water level is just by regulating valve 2 controls on the high pressure soft water pipeline 1.In operational process, per tour is then passed through drum downtake wash water valve 9 and 15 blowdowns of upcast wash water valve once.When drum 3 hypertonia, can regulate drum 3 pressure by regulating induction valve 6 apertures.When drum 3 pressure surpassed safety valve 4 pressure-bearings suddenly, safety valve 4 can be opened steam bleeding automatically, and after pressure reduced, safety valve 4 was closed automatically.
The above only is embodiment of the present utility model; but be not so promptly limit scope of patent protection of the present utility model; equivalent structure that every utilization the utility model specification sheets and accompanying drawing content are done changes, and all is included in the claim that the utility model contains.
