Abstract
The utility model provides an oxygen enriching device by blast furnace film method which comprises a filter, wherein the filter is connected with a blower, and the blower is connected with a film method oxygen enriching generator through a pipe, and the film method oxygen enriching generator is connected with a steam separator, and the steam separator is connected with a blast furnace blower. The utility model which widely used in the blast furnace smelting can increase the oxygen quantity when the blast furnace is operating, decrease combustion air surplus coefficient, reduce heat quantity carried by the exhausted gas, increase combustion temperature in the blast furnace, thereby the utility model has the advantages of lowing cost and saving energy.
Description
Technical field
The utility model relates to metallurgical technology field, is a kind of blast furnace film oxygen enriching device.
Background technology
The utility appliance of iron-smelting blast furnace has more kind, but does not still have a kind of utility appliance that increases oxygen when the iron-smelting blast furnace internal combustion at present.Common aid burning method is a forced ventilation when blast-furnace roasting, increases ventilation, but this method cost height, and effect is not good enough.
Summary of the invention
The purpose of this utility model is, a kind of blast furnace film oxygen enriching device is provided, and it is used for steelmaking furnace, oxygen when making blast-furnace roasting increases, and reduces the combustion air coefficient of excess, and exhaust heat is reduced, increase stove internal combustion temperature, realization reduces cost, the purpose of save energy.
The utility model for achieving the above object, be achieved through the following technical solutions: the blast furnace film oxygen enriching device, it has strainer, strainer is connected with gas blower, gas blower is connected with the film oxygen enriching producer by pipeline, the film oxygen enriching producer is connected with steam separator, and steam separator is connected with blast furnace blowing engine.Even pressure vessel is installed between steam separator and blast furnace blowing engine.Steam separator bottom pipe laying pump, in-line pump is connected with the water cycle vacuum pump by pipeline.Water trap is installed on the top of steam separator.The input terminus of water trap is installed second steam separator.
The utility model is used for blast-furnace smelting, and the oxygen in the time of can making blast-furnace roasting increases, and can reduce the combustion air coefficient of excess, can reduce exhaust heat significantly, increases the quantity combusted in the stove, reduces cost save energy.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Embodiment
1 is strainer among the figure, and strainer 1 is connected with gas blower 2, and gas blower 2 is connected with film oxygen enriching producer 3 by pipeline, and film oxygen enriching producer 3 is connected with steam separator 4, and steam separator 4 is connected with blast furnace blowing engine 7.Even pressure vessel 8 is installed between steam separator 4 and blast furnace blowing engine 7.Steam separator 4 bottom pipe laying pumps 9, in-line pump 9 is connected with water cycle vacuum pump 5 by pipeline 10.Water trap 13 is installed on the top of steam separator 4.The output terminal of water trap 13 is installed second steam separator 6.Various block construction described in the utility model is the known products structure.When the utility model uses, be connected with the gas blower on blast furnace or the hotblast stove, the oxygen that makes is at last added cold air duct, after the hotblast stove preheating, send into blast furnace, also the oxygen that makes can be sent into the gas blower suction port mixes, deliver to blast furnace after blower fan pressurization, the air oxygen level when reaching blast-furnace roasting is greater than 21% purpose.11 is blast furnaces among the figure, the 12nd, and hotblast stove.
