Description
Technical field
The utility model relates to a kind of spiral nozzle formula blast furnace roof atomization dispensing device for water, belongs to the metallurgy industry blast furnace roof atomization equipment technical field of fetching water.
Background technology
At present, metallurgy industry blast furnace roof water injection device is generally all used nitrogen atomization formula dispensing device for water, and every each nozzle of blast furnace, in the middle of use procedure, occurs following problem: the one, and spray nozzle clogging, causes the furnace roof skewness of fetching water.The 2nd, nitrogen pipeline is stopped up, distortion, and fetching water cannot atomization, and water directly pours into high furnace interior, causes temperature part in stove to plunge, potential larger potential safety hazard.The 3rd, difficult in maintenance, trouble location mostly occurs in stove, does not have the chance of long-time damping down blowing out to process.As be replaced by the electricity dispensing device for water that surges, and to inject capital into more, initial failure period is long, and increases trouble spot.
Utility model content
The utility model object is to provide a kind of spiral nozzle formula blast furnace roof atomization dispensing device for water, the cooling high pressure water of blast furnace top is become to small liquid pearl by spiral nozzle to be sprayed, form atomized spray, replace nitrogen atomization to spray, realize the effect of Quick uniform cooling, solve the problem existing in background technology.
The technical solution of the utility model is:
A kind of spiral nozzle formula blast furnace roof atomization dispensing device for water, comprise spiral nozzle, water pipe one, protecting pipe, water pipe two, punched bend, water pipe three and high top pressure water ring pipe, water pipe one skin is provided with protecting pipe, water pipe one one end is provided with spiral nozzle, and stretch in blast furnace, the other end is communicated with water pipe two, the other end of water pipe two is by punched bend and water pipe tee joint, the other end of water pipe three is communicated with high top pressure water ring pipe, in the shape of a spiral, bore outwards diminishes from inner described spiral nozzle gradually.
Described water pipe one, water pipe two and water pipe three are weldless steel tube.
Adopt the utility model, when blast furnace roof temperature raises, open blast furnace roof water injection control valve, the cooling high pressure water of blast furnace top passes through spiral nozzle, after tangent and collision, become the ejection of small liquid pearl with helicoidal surface, form atomized spray, replace nitrogen atomization to spray, realize the effect of Quick uniform cooling.
The beneficial effects of the utility model are: spiral nozzle be difficult for to stop up, safe, maintenance is little.Multi-layer sprinkling be can realize, quick, uniform decrease in temperature realized.Less energy-consumption, low cost, without additional any source of the gas or electric (hydraulic pressure) power set.The demand that can adapt to the different type of furnaces.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: spiral nozzle 1, water pipe 1, protecting pipe 3, water pipe 24, punched bend 5, water pipe 36, high top pressure water ring pipe 7, stove skin 8.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of spiral nozzle formula blast furnace roof atomization dispensing device for water, comprise spiral nozzle 1, water pipe 1, protecting pipe 3, water pipe 24, punched bend 5, water pipe 36 and high top pressure water ring pipe 7, adopt spiral nozzle, weldless steel tube is made, spiral nozzle 1 in the shape of a spiral, bore outwards diminishes gradually from inner, water pipe 1, it is the weldless steel tube of φ 57*3.5 that water pipe 24 and water pipe 36 adopt specification, punched bend 5 models are DN50, 90 °, during installation, original nitrogen atomization dispensing device for water center nitrogen tube is pulled down, be replaced by the spiral nozzle 1 having completed, water pipe one 2 skins are provided with protecting pipe 3, water pipe one 2 one end are provided with spiral nozzle 1, and spiral nozzle 1 is stretched into 800mm place in blast furnace, the other end is communicated with water pipe 24, the other end of water pipe 24 is communicated with water pipe 36 by punched bend 5, the other end of water pipe 36 is communicated with high top pressure water ring pipe 7, high pressure water pressure in high top pressure water ring pipe 7 is 5-7Kg.
When blast furnace roof temperature rise, open the furnace roof by-pass valve control of fetching water, high top pressure water by with spiral nozzle 1,, after tangent and collision, become small liquid pearl (particle) ejection and form atomized spray with helicoidal surface, realize Quick uniform cooling-down effect.
Claims (2)
1. a spiral nozzle formula blast furnace roof atomization dispensing device for water, it is characterized in that comprising spiral nozzle (1), water pipe one (2), protecting pipe (3), water pipe two (4), punched bend (5), water pipe three (6) and high top pressure water ring pipe (7), water pipe one (2) skin is provided with protecting pipe (3), water pipe one (2) one end is provided with spiral nozzle (1), and stretch in blast furnace, the other end is communicated with water pipe two (4), the other end of water pipe two (4) is communicated with water pipe three (6) by punched bend (5), the other end of water pipe three (6) is communicated with high top pressure water ring pipe (7), described spiral nozzle (1) in the shape of a spiral, bore outwards diminishes gradually from inner.
