Description
Technical Field
The utility model relates to a sintering ignition furnace specifically is a nozzle arrangement structure of sintering ignition furnace.
Background
The sintering ignition furnace is important equipment in a sintering process flow and is divided into a combustion section and a heat preservation section, gas fuels such as blast furnace gas and the like are mixed with air and then are ignited by a nozzle of a sintering ignition furnace to generate high-temperature flame, so that solid fuels in a sintering mixture are ignited and combusted, the sintering mixture is sintered at the high temperature of the combustion section of the sintering ignition furnace, the heat storage and the heat preservation are carried out on the sintering mixture by utilizing the heat preservation section of the sintering ignition furnace, and finally, the sintered ore required by the blast furnace production is achieved.
The existing sintering ignition furnace burner arrangement is as follows: first nozzle is 1030 mm with the second nozzle interval, the second nozzle is 1670 mm with the third nozzle interval, first nozzle is 1030 mm with the external wall interval of ignition furnace, first nozzle is far away from sintering ignition furnace cloth one side external wall distance, and the distance is nearer between the three rows of nozzles, the purpose of doing so is in order to concentrate formation high temperature region, improve the sintering effect, but discovery sintering ignition furnace is close to the condition that the cloth side took place to scurry into the air in the operation process, and simultaneously, the condition of taking place sintering mixture overburning, cause fuel consumption to rise, the sintering is returned the ore deposit and is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, provide a nozzle arrangement structure of sintering ignition furnace, adjust the installation direction and the interval of nozzle to reach and reduce fuel consumption, improve the effect of sintering yield.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a nozzle arrangement structure of sintering ignition furnace, includes that first row of nozzle, second row of nozzle, third row of nozzle are arranged the nozzle, and first row of nozzle setting is in 400mm position departments apart from sintering ignition furnace cloth side outer wall, and first row of nozzle is the 20 jiaos of sintering ignition furnace cloth side outer wall slope all the time, and nozzle, third row of nozzle are arranged perpendicularly to the second, and the nozzle interval equals to be 1650mm in the three rows.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, beneficial effect is:
(1) first row of nozzle inclines to cloth side outer wall, reduces with cloth side outer wall interval, makes sintering ignition furnace sintering section form hot air curtain barricade in the combustion process, and the cold air of entering is scurried to isolated sintering ignition furnace cloth side, guarantees sintering ignition furnace combustion effect, improves ignition temperature, reduces solid fuel consumption, concrete effect: the ignition temperature is increased by 80 ℃, and the solid fuel consumption is reduced by 0.1 percent.
(2) The three rows of burners are arranged at equal intervals, so that the burning time of the sintering ignition furnace is ensured, the sintering return ore rate is reduced by 4%, and the yield is improved by 4%.
Further, the utility model discloses preferred scheme is:
the included angle between the axis of the first row of burners and the axis of the air pipeline is 70 degrees.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic view of an included angle between the axis of the first row of burners and the axis of the air duct;
in the figure: 1. sintering an ignition furnace; 2. a third row of burners; 3. a combustion section; 4. a second row of burners; 5. a first row of burners; 6. a gas pipeline; 7. an air duct; 8. a cloth side outer wall; 9. and a material distribution mechanism.
Detailed Description
The invention will be further explained with reference to the following embodiments shown in the drawings.
Referring to fig. 1 and 2, the burner arrangement structure of the sintering ignition furnace 1 is as follows: the first row of burners 5 are arranged at a position which is about 400mm away from the outer wall 8 of the sintering ignition furnace 1 at the cloth side, the first row of burners 5 uniformly incline to the outer wall 8 at the cloth side by an angle of 20 degrees, and meanwhile, the included angle between the axis of the first row of burners 5 and the axis of the air pipeline 7 is 70 degrees; the second row of burners 4 and the third row of burners 5 are vertically arranged, and the three rows of burners are equal in distance and are 1650 mm.
In the embodiment, the first row of burners 5 are inclined towards the outer wall 8 on the cloth side, compared with the existing sintering ignition furnace with the distance of 1030 mm between the first burners and the outer wall 8 on the cloth side, the distance between the first row of burners 5 and the outer wall 8 on the cloth side is greatly reduced, so that the sintering section 3 of the sintering ignition furnace 1 can form a hot air curtain wall in the combustion process, cold air entering from the cloth side is isolated, the combustion effect of the sintering ignition furnace is ensured, the ignition temperature is improved, and the solid fuel consumption is reduced; through the test: the ignition temperature is increased by 80 ℃, and the solid fuel consumption is reduced by 0.1 percent; meanwhile, the first row of burners 5, the second row of burners 4 and the third row of burners 5 are arranged at equal intervals, so that the combustion time of the sintering ignition furnace 1 is also ensured; through the test: the sintering return ore rate is reduced by 4 percent, and the yield is improved by 4 percent.
