Abstract
The invention relates to the improvement of a cooling structure of an ironmaking blast furnace, belongs to the technical field of ironmaking equipment, and is an ironmaking blast furnace with a cooling water pipe, and the ironmaking blast furnace comprises a furnace body, the top of the furnace body is provided with a coal gas pipe and a big hopper, the top and the bottom of the big hopper are respectively provided with a small hopper and a big bell, the top and bottom of the small hopper are respectively provided with a bell control valve and a small bell; the lower part of the furnace body is provided with a supporting rack, a furnace surrounding hot air pipe surrounding the furnace body is arranged bellow the supporting rack, a straight blowpipe is arranged between the furnace surrounding hot air pipe and the furnace body; one side of the bottom of the furnace body is provided with a slag outlet, the other side is provided with an iron outlet; the ironmaking blast furnace is characterized in that the annular cooling water pipe surrounding the outer side of the furnace body is arranged between the furnace surrounding hot air pipe and the straight blowpipe, a plurality of spray heads are arranged bellow the annular cooling water pipe, the spray heads are directly toward the straight pipe; the ironmaking blast furnace solves the problems that a straight blowpipe in a traditional ironmaking blast furnace is too high in temperature, need to be replaced frequently, affects the production schedule and is high in cost, and the like, and can be mainly used in the ironmaking blast furnace.
Description
(i) technical field: the present invention relates to the improvement of iron-smelting blast furnace cooling structure, belong to ironmaking equipment technical field, especially a kind of iron-smelting blast furnace with water-cooled tube.
(ii) background technology: at present, the general blast furnace ironmaking that adopts of ironmaking, blast furnace ironmaking has advantages of that output is large, productivity is high and cost is low, that other iron smelting methods are incomparable, but the belly pipe in blast furnace heat air delivery device, due to often under hot environment, causes belly pipe often damaged, changes more frequent, the progress that not only impact is produced, but also cause cost high.Therefore, designing a kind of iron-smelting blast furnace that can address the above problem well is extremely necessary.
(iii) summary of the invention: object of the present invention is exactly will solve belly pipe excess Temperature in traditional iron-smelting blast furnace, need to often change, affect production schedule and the problem such as cost is higher, and a kind of iron-smelting blast furnace with water-cooled tube is provided.
Concrete scheme of the present invention is: for traditional iron-smelting blast furnace, improve, it has body of heater, gas pipe and large hopper are equipped with in body of heater top, and little hopper and lower bell are equipped with respectively in top and the bottom of large hopper, and bell controlling valve and upper bell are equipped with respectively in the top of little hopper and bottom; Lower portion of furnace body is equipped with bracing frame, and the ring oven heating duct around body of heater is equipped with in bracing frame below, between ring oven heating duct and body of heater, belly pipe is housed; Bottom of furnace body one side has slag notch, and opposite side has iron notch; It is characterized in that: the annular cooling water pipe around body of heater outside is housed between described ring oven heating duct and belly pipe, and several spray headers are equipped with in annular cooling water pipe below, and spray header is all arranged over against belly pipe.
The present invention is simple in structure, easy to use, can cool to the belly pipe of heat air delivery device in iron-smelting blast furnace, avoids belly pipe due to overheated and damaged, and the ，Gei enterprise in work-ing life that has greatly extended belly pipe has brought huge economic benefit.
(iv) accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
In figure: 1-slag notch, 2-belly pipe, 3-annular cooling water pipe, 4-body of heater, 5-gas pipe, the large hopper of 6-, the little hopper of 7-, 8-bell controlling valve, 9-upper bell, 10-lower bell, 11-ring oven heating duct, 12-bracing frame, 13-spray header, 14-iron notch.
(v) embodiment:
Referring to Fig. 1, the present invention has body of heater 4, and gas pipe 5 and large hopper 6 are equipped with in body of heater 4 tops, and small powder bucket 7 and lower bell 10 are equipped with respectively in top and the bottom of large hopper 6, and bell controlling valve 8 and upper bell 9 are equipped with respectively in the top of small powder bucket 7 and bottom; Bracing frame 12 is equipped with in body of heater 4 bottoms, and the ring oven heating duct 11 around body of heater 4 is equipped with in bracing frame 12 belows, between ring oven heating duct 11 and body of heater 4, belly pipe 2 is housed; Body of heater 4 bottom one sides have slag notch 1, and opposite side has iron notch 14; Particularly: the annular cooling water pipe 3 around body of heater 4 outsides is housed between described ring oven heating duct 11 and belly pipe 2, and several spray headers 13 are equipped with in annular cooling water pipe 3 belows, spray header 13 is all arranged over against belly pipe 2; Formed the present invention.
