The spay blowing equipment structurally comprises a pressurizing machine, a spay gun and an electric control valve, wherein a special pipeline is arranged between the spray gun and the pressurizing machine, an electric control valve is arranged on the special pipeline, the electric control valve is connected with a computer, the front end of the spray gun passes through the pipe wall of a blast furnace air supply straight blowing pipe to be obliquely inserted into the blast furnace air supply direct blowing pipe, the front end of the blast furnace air supply direct blowing pipe is connected with a blast furnace tuyere which is arranged on the furnace wall of the blast furnace, and the front end of the spray gun is aligned with the blast furnace tuyere. Compared with the prior art, the spay blowing equipment of the utility model has the characteristics that the excessive coal gas in the steel and iron factories is sufficiently utilized as resources, so the blast furnace saves coke, the consumption can be reduced, the production cost can be reduced and the like. Thereby, the utility model has good popularization and application values.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of blast furnace ironmaking, especially a kind of blowing device of jet in blast furnace coal gas or reducing gas.
Background technology
The blast furnace that is used to smelt iron is the big power consumer of Steel Plant, the energy-saving and cost-reducing of blast furnace is the key link that is related to Steel Plant's economic benefit, therefore, the coal gas that Steel Plant produce is all being recycled both at home and abroad, the research that Steel Plant's residual gas is jetted in blast furnace, most of producers still are limited to theoretical investigation, domestic really directly applying to produced actual also not having at present, key is the suite of equipment that does not have coal gas to be blown in the blast furnace, because at present, good solution is not arranged also, therefore, cause Steel Plant's energy dissipation, cost increases, and influences environment.
The utility model content
Technical assignment of the present utility model is to provide a kind of blowing device at above-mentioned deficiency of the prior art, this a kind of blowing device has the abundant coal gas of Steel Plant's surplus of recycling as resource, make blast furnace save coke, reduce consuming the characteristics that reduce production costs.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises press, spray gun and electric control valve, be provided with pipe special between described spray gun and the press, described pipe special is provided with electric control valve, described electric control valve links to each other with computer, the tube wall that described spray gun front end passes blast furnace air-supply belly pipe tilts to be inserted in the blast furnace air-supply belly pipe, the front end of described blast furnace air-supply belly pipe is connected with blast-furnace tuyere, described blast-furnace tuyere is arranged on the furnace wall of blast furnace, and described spray gun front end is aimed at blast-furnace tuyere.
Inclination angle between described spray gun and the blast furnace air-supply belly pipe is 9 °-15 °.
A kind of blowing device of the present utility model is compared with prior art, has following outstanding beneficial effect: the coal gas of fully recycling Steel Plant's surplus is realized recycling economy as resource, make blast furnace save coke, reduce consuming, reduce production costs, reasonable in design, characteristics such as easy to use.

Embodiment
With reference to explaining below 1 pair of a kind of blowing device work of the present utility model of Figure of description.
A kind of blowing device of the present utility model, its structure comprises press 3, spray gun 8 and electric control valve 5, be provided with pipe special 4 between described spray gun 8 and the press 3, described pipe special 4 is provided with electric control valve 5, described electric control valve 5 links to each other with computer 2, the tube wall that described spray gun 8 front ends pass blast furnace air-supply belly pipe 6 tilts to be inserted in the blast furnace air-supply belly pipe 6, the front end of described blast furnace air-supply belly pipe 6 is connected with blast-furnace tuyere 7, described blast-furnace tuyere 7 is arranged on the furnace wall of blast furnace 1, and described spray gun 8 front ends are aimed at blast-furnace tuyere 7.
Inclination angle between described spray gun 8 and the blast furnace air-supply belly pipe 6 is 9 °-15 °.
When carrying out in blast furnace 1, jetting coal gas, when gas pressure is pressurized to the pressure that is higher than the blast-furnace hot-air that is blown into from blast furnace air-supply belly pipe 6 by press 3, by computer 2 control electric control valves 5, open electric control valve 5, coal gas can be sprayed from spray gun 8, and spray into together in the blast furnace burner hearth in company with the blast-furnace hot-air that enters from blast furnace air-supply belly pipe 6 right-hand members.
A kind of blowing device of the present utility model, the coal gas of not only can jetting: comprise blast furnace gas, coal gas of converter, coke-oven gas and mixed gas, and the some other reducing gas that can jet hydrogen, Sweet natural gas, methane and be rich in carbon monoxide.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
Claims (2)
