Abstract
The utility model discloses a direct gas mixing type superheated steam generating pot which comprises a pot body, a steam homogenizing pipe and a stainless steel screen distributor. The steam homogenizing pipe is arranged at the lower end inside the pot body in a crosswise mode, the stainless steel screen distributor is arranged at the upper end inside the pot body in a crosswise mode, and an outer heat source superheated steam inlet is arranged on the side wall of the pot body where the steam homogenizing pipe is arranged. A low-pressure saturated steam inlet is arranged on the side wall of the pot body where the stainless steel screen distributor is arranged, wherein the low-pressure saturated steam is generated in a waste heat recovery process. A mixed superheated steam outlet is arranged on the top portion of the pot body, and a condensate drain port is arranged on the bottom portion of the pot body. A direct gas mixing mode is adopted in the direct gas mixing type superheated steam generating pot to generate the low-pressure superheated steam, and therefore steam can be supplied continuously and stably, outer mechanical power is not consumed, waste heat recovery rate can be effectively improved, and greater economic benefits and social benefits can be generated.
Description
Technical field
The utility model relates to a kind of steel-smelting electric furnace, the direct mixed-gas type superheated steam of AOD stove waste heat recovery generation tank, relates in particular to a kind of direct mixed-gas type superheated steam generation tank of using the vapour demand for metallurgy industry steel-smelting electric furnace, the follow-up VD stove evacuation of AOD stove.
Background technology
Electric furnace, AOD stove are the very general technological equipments of present smelter smelting iron and steel (comprising stainless steel smelting), and the waste gas residual heat recovery operation that electric furnace, AOD stove produce in converting process is an important task in the present industry energy conservation emission reduction work.Because being subject to the impact of smelting process, electric furnace, AOD furnace exhaust variations in temperature are relatively more frequent, fluctuating range is relatively large, can only be by a kind of low-pressure saturated steam of differential pressure type storage heater output of waste heat boiler and water-steam system postposition, this steam pressure is generally at 0.8～1.2MPa.
And for the required steam of follow-up VD stove evacuation, the pressure of steam pressure and above-mentioned low-pressure saturated steam is basic identical, but generally need steam superheating to 220～240 ℃.At present, under the condition that does not have the external heat source medium, the waste heat boiler water-steam system is follow-up can be arranged the differential pressure overheating heat accumulator that declines and makes steam that certain degree of superheat be arranged, but the saturated vapor overtemperature that can only make this little overheating heat accumulator improves≤10 ℃, still do not reach 220～240 ℃ use the vapour requirement; Under the condition that the external heat source medium is arranged, usually adopt mechanical mode to mix gas, with two kinds of vapor mixing, this mode relatively hot loss is large, and needs to consume external impetus, is unfavorable for promoting the utilization rate of waste heat recovery by the work of machine operation mode.
The utility model content
Be to solve the deficiencies in the prior art, the purpose of this utility model be to provide a kind of thermal losses little, do not need to consume powered attendant-controlled wheelchairs direct mixed-gas type superheated steam generation tank.
The technical scheme that the utility model adopts is:
Direct mixed-gas type superheated steam generation tank, it is characterized in that, comprise tank body, equal steam pipe and stainless steel cloth distributor, described equal steam pipe is horizontally installed on the tank interior lower end, described stainless steel cloth distributor then is horizontally set at the tank interior upper end, and be provided with the import of external heat source superheated steam on the sidewall of the tank body of described equal steam pipe position, then be provided with waste heat recovery on the sidewall of the tank body at described stainless steel cloth dispenser location place and produce the low-pressure saturated steam import, the top of described tank body also is provided with mixes the superheated steam outlet, and the bottom is provided with the condensate drain mouth.
Further, have a plurality of equal steam vents on the described equal steam pipe.And the diameter of described equal steam vent is identical.
And the pressure 〉=0.2MPa of waste heat recovery low-pressure saturated steam import, and the temperature of external heat source superheated steam import 〉=260 ℃.
The beneficial effects of the utility model are: the utility model adopts the mode of directly mixed gas to produce low-pressure superheated steam, satisfy electric furnace, the low-pressure steam of AOD stove waste heat recovery is for follow-up VD stove, a kind of superheated steam and a kind of low-pressure saturated steam directly mix in tank body, then carry out steam supply, and distributed uniform, reduced two media in temperature, under the different condition of pressure, especially in the large temperature difference, the thermal shock that when mixing under the large pressure reduction condition system is produced, so that steam supply can be continuously, steadily, do not consume exterior mechanical power, and energy Effective Raise heat recovery rate produces larger economic benefit and social benefit.
