Description
Technical field
The utility model relates to a kind of measurement top-blown oxygen converter gaseous tension device, can be applicable in all converter vaporization cooling Waste Heat Boiler Designs.
Background technology
Top-blown oxygen converter produces a large amount of high-temperature furnace gas between the blowing process, is the dust (80 ~ 100g/m3) of about 60% in furnace gas containing a large amount of CO and iron-holder.Furnace gas forms flue gas after going out fire door, and high-temperature flue gas can become coal gas after cooling and purifying process, is used.Feature due to converter steelmaking determines that the fluctuation of converter gas is large, and exhaust gas volumn and smoke components change with the change of smelting cycle.Therefore, in order to ensure gas cleaning effect, carry out RECOVERY OF CONVERTER GAS safely and effectively, be provided with micro-differential pressure device in OG device, to make gaseous tension and outside atmospheric pressure difference in fire door place and petticoat pipe keep stable, general control is within the scope of ± 20Pa.
Existing measurement top-blown oxygen converter gaseous tension device is arranging differential pressure device near converter mouth place.Due to differential pressure device be in the exceedingly odious operating mode of converter mouth for a long time under (high temperature, flame), therefore differential pressure measurement device is inaccurate, and micro-pressure-difference is short for device lifetime, and maintenance cost is high.Therefore we are in the urgent need to a kind of device of measurement top-blown oxygen converter gaseous tension newly, to ensure the accuracy measured.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of measurement top-blown oxygen converter gaseous tension device, and this device can not only ensure the accuracy measured, and long service life.
The technical scheme that the utility model adopts is: a kind of measurement top-blown oxygen converter gaseous tension device, it comprises micro-pressure-difference device, and described micro-pressure-difference device is arranged on I section of flue of top-blown oxygen converter, and is positioned on converter high-rise frame.
By such scheme, totally 4, described micro-pressure-difference device, is circular layout on I section of flue of top-blown oxygen converter.
By such scheme, described micro-pressure-difference device installation above the 23.2m platform of converter high-rise frame, center absolute altitude 25.5m.
By such scheme, 4 micro-pressure-difference devices are evenly arranged on I section of flue of top-blown oxygen converter.
The utility model can ensure the accuracy measured, and long service life, reduce maintenance cost, save production cost; Maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model.
Fig. 2 is the A-A sectional view in Fig. 1.
In figure: 1, I section of flue, 2,23.2m platform on converter high-rise frame, 3, micro-pressure-difference device, 4, fire door.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
See Fig. 1, Fig. 2, a kind of measurement top-blown oxygen converter gaseous tension device, it comprises 4 micro-pressure-difference devices 3, and 4 micro-pressure-difference device 3 uniform ring are located on I section of flue 1 of top-blown oxygen converter.
In the present embodiment, 4 described micro-pressure-difference devices 3 are positioned at the top of the 23.2m platform 2 on converter high-rise frame, center absolute altitude 25.5m.
Micro-pressure-difference device 3 is not arranged on fire door 4 by the utility model, but micro-pressure-difference device 3 is arranged on I section of flue 1, make micro-pressure-difference device 3 not by the impact of thermal-flame, both ensure that the accuracy of measurement gas pressure, and extended again the work-ing life of micro-pressure-difference device 3.
Differential pressure device 3 designs at I section of flue 1 place by the utility model, and distance I section of lower collecting box is about 2m place, is positioned at the top of the 23.2m platform 2 of converter high-rise frame, has namely completely cut off flame and high temperature, is beneficial to again maintenance convenient.
Claims (1)
