Abstract
The utility model provides a double gun channel blow pipe of an air-intake system of an ironmaking blast furnace, belonging to an auxiliary attachment field of blast furnace ironmaking. The technical scheme is that the double gun channel blow pipe includes a blow pipe body and a coal powder injection gun channel arranged on the blow pipe body; the coal powder injection gun channel includes a gun channel A and a gun channel B which are respectively distributed on two sides of the blow pipe body; front ends of center lines of the gun channel A and the gun channel B are intersected with the center line of the blow pipe body; and an included angle alpha between the center line of the gun channel A or the gun channel B and the center line of the blow pipe body is 11-15 DEG. The scheme has two coal powder injection gun channels which simultaneously inject coal powders or respectively inject coal powders and flue gas so as to further increase coal powder injection quantity or improve the coal powder combustion rate; the utility model has characteristics of coke saving in the blast furnace, energy consumption reduction, production cost reduction, environment improvement and simple structure, and meets requirements of blast furnaces with different models and volumes by designing the angle between the coal powder injection gun and the blow pipe.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of blast furnace ironmaking, especially a kind of iron-smelting blast furnace air inlet system rush-harvesting and rush-planting road belly pipe.
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 blast furnace of present most Steel Plant is all taked the method for coal injection in stove, reduces production costs to reduce coke consumption.Conventional blowing method is on blast furnace air-supply belly pipe a rifle road to be installed to insert a spray gun, when the coal powder injection of blast furnace list rifle, causes rate of combustion to reduce after its injecting coal quantity acquires a certain degree easily, hinders the further raising of coal injection amount.For realizing this purpose, the publication number of Shanghai Meishan Iron﹠ Steel Co., Ltd's application is: CN201321464, the patent No. is: 200820214896.3, patent name is: a kind of utility model patent of rush-harvesting and rush-planting coal powder injection device, it has solved the shortcoming of single rifle coal powder injection to a certain extent, but it exists versatility poor, the shortcoming that the coal powder injection effect is not satisfactory.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and a kind of simple in structure, low cost of manufacture is provided, and makes it have the demand that can adapt to different model, differing capacities blast furnace easy to use by the angle between design coal spouting gun and the belly pipe.
The utility model is realized by following technical measures: a kind of iron-smelting blast furnace air inlet system rush-harvesting and rush-planting road belly pipe, it comprises the coal spouting gun road on belly pipe body and the belly pipe body, described coal spouting gun road comprises A rifle road and B rifle road, described A rifle road and B rifle road are arranged in belly pipe body both sides, described A rifle road and B rifle road medullary ray front end and belly pipe body medullary ray intersect, and the angle α between described A rifle road medullary ray and/or B rifle road medullary ray and the belly pipe body medullary ray is 11 °～15 °.This scheme possesses two coal spouting gun roads, and the function of coal powder injection simultaneously of two rifle roads or a coal one combustion gas can further improve injecting coal quantity or improve coal combustion rate, has the blast furnace of making and saves coke, reduces consuming, and reduces production costs and improves the characteristics of environment; The utlity model has simple in structure, low cost of manufacture simultaneously, make it have the demand that can adapt to different model, differing capacities blast furnace easy to use by the angle between design coal spouting gun and the belly pipe.
Further improvement of the utility model also has, and the medullary ray and the belly pipe body medullary ray in A rifle road and B rifle road intersect in same point.Its complete symmetrical structure can increase rate of combustion, when especially adopting a coal one combustion gas use-pattern, and its better effects if.
The utility model is in order further to increase its versatility, and it further improves also has, and to sciagraph, is the center of circle with belly pipe body medullary ray from the P of the aft end face of belly pipe body, and the angle between described A rifle road and the B rifle road is that β is 90 °～180 °.
The beneficial effects of the utility model are passed through foregoing description as can be known: the utility model is simple in structure, the processing and manufacturing cost is low, on purpose design the position relation between belly pipe and the rifle road, increased its versatility effectively, made it have the demand that can adapt to different model, differing capacities blast furnace easy to use.
