Abstract
The utility model relates to preheating oven Anti-freezing gas line structure, by preheating oven gas main road, orifice-plate flowmeter, coal gas drainer I and coal gas drainer II forms, orifice-plate flowmeter is arranged on preheating oven gas main road, coal gas drainer I and coal gas drainer II is separately positioned on the both sides of orifice-plate flowmeter, arranges control valve I and control valve II between coal gas drainer I and coal gas drainer II and preheating oven gas main road.Described coal gas drainer I and coal gas drainer II is electric temperature control coal gas drainer.The utility model can prevent winter preheating oven gas valve to freeze, and ensures that preheating oven normally burns stove, thus ensures blast furnace air temperature, avoid removing roasting gas line with fire, eliminate the hidden danger that gas safety accident occurs.
Description
Technical field
The utility model relates to preheating oven gas line mounting structure, particularly preheating oven Anti-freezing gas line structure.
Background technology
The blow-on in December, 2005 of Anshan iron and steel plant 3 blast furnace, heat size 3200m3.Hotblast stove is 4 outside combustion stoves, 2 preheating ovens, and blowing system is that two burnings two send staggered parallel blowing.Preheating oven gas main road diameter 600mm, coal gas needs the orifice-plate flowmeter through a diameter 600mm before entering preheating oven on total pipeline, owing to containing a certain proportion of moisture in coal gas, converges after flowing through fow-through orifice before and after orifice plate.Be easy to preheating oven gas valve to freeze to winter, preheating oven normally cannot burn stove.Not only traditional way removes roasting gas line with fire, loses time but also gas safety accident easily occurs.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of preheating oven Anti-freezing gas line structure, and winter can be prevented freezing, ensures that preheating oven normally burns stove.
For achieving the above object, the utility model realizes by the following technical solutions:
Preheating oven Anti-freezing gas line structure, by preheating oven gas main road, orifice-plate flowmeter, coal gas drainer I and coal gas drainer II forms, orifice-plate flowmeter is arranged on preheating oven gas main road, coal gas drainer I and coal gas drainer II is separately positioned on the both sides of orifice-plate flowmeter, arranges control valve I and control valve II between coal gas drainer I and coal gas drainer II and preheating oven gas main road.
Described coal gas drainer I and coal gas drainer II is electric temperature control coal gas drainer.
Compared with prior art, the beneficial effects of the utility model are:
Preheating oven Anti-freezing gas line structure, can prevent winter preheating oven gas valve to freeze, and ensures that preheating oven normally burns stove, thus ensures blast furnace air temperature, avoid removing roasting gas line with fire, eliminate the hidden danger that gas safety accident occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-preheating oven gas main road 2-orifice-plate flowmeter 3-coal gas drainer I 4-coal gas drainer II5-control valve I 6-control valve II 7-preheating oven gas valve I 8-preheating oven gas valve II 9-1# preheating oven 10-2# preheating oven
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
Embodiment: as shown in Figure 1, preheating oven Anti-freezing gas line structure, by preheating oven gas main road 1, orifice-plate flowmeter 2, coal gas drainer I3 and coal gas drainer II4 forms, and coal gas drainer I3 and coal gas drainer II4 is electric temperature control coal gas drainer, authentication code rzz the Liao Dynasty 125-05, voltage rating 220v, water seal pressure 0.03Mpa.Orifice-plate flowmeter 2 is arranged on preheating oven gas main road 1, coal gas drainer I3 and coal gas drainer II4 is separately positioned on the both sides of orifice-plate flowmeter 2, arranges control valve I5 and control valve II6 between coal gas drainer I3 and coal gas drainer II4 and preheating oven gas main road 1.
Be only ultimate principle of the present utility model above, not impose any restrictions the utility model, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
