Description
Technical field
The utility model is related to a kind of auxiliary equipment of electric furnace, and in particular to a kind of cooling of electric furnace gasification cooling flue
Section.
Background technology
The gasification cooling flue of electric furnace is one of the necessaries for realizing energy recovery and green production, and it is used for electricity
The flue gas produced in stove steelmaking process is cooled down and reclaimed.First paragraph of the current domestic gasification cooling flue from electric furnace side
(i.e. cooling section) is an entirety, and such design have ignored the Temperature Distribution in flue, and flue is extended to from import to inner side
The position on arc top is high-temperature area, and maximum temperature can reach 1300 DEG C, following position be in gentle low-temperature region, temperature exists
Between 800 DEG C -1000 DEG C.The service life of normal gasification cooling flue was up to 4 years, and the life-span of high-temperature area can be only sustained at
2 years, damageable zone is not carried out independently to consider, relatively reduce the service life of flue.
Utility model content
The utility model provides a kind of cooling section of electric furnace gasification cooling flue so that the high-temperature area of flue is relatively only
It is vertical, can process at short notice after it breaks down, and damageable zone can in time be changed, reduce maintenance load and
Maintenance cost.
The technical solution of the utility model is as follows：
A kind of cooling section of electric furnace gasification cooling flue, including leading portion, back segment and flange, the leading portion passes through institute with back segment
State flange to link together, the water screen tube one that flue axis is extended, the back segment are arranged parallel to inside the leading portion
Inside is arranged parallel to the water screen tube two that flue axis is extended；The leading portion is entered by water inlet pipe one and water circulating pump
Supply mains connects, and is connected with the flue backwater rising main of drum by return pipe one；The back segment passes through water inlet pipe two and follows
The water inlet manifold connection of ring water pump, is connected by return pipe two with the flue backwater rising main of drum；Water circulating pump passes through back
Supply mains is connected with drum.
The cooling section of described electric furnace gasification cooling flue, its preferred version is that the flange is by asbestos seal.
The cooling section of described electric furnace gasification cooling flue, its preferred version is, the caliber of water inlet pipe one and water inlet pipe two
At least 150mm.
The cooling section of described electric furnace gasification cooling flue, its preferred version is, the caliber of return pipe one and return pipe two
At least 200mm.
The cooling section of described electric furnace gasification cooling flue, its preferred version is that the caliber of return main is at least
300mm。
The beneficial effects of the utility model are：
1st, the utility model carries out subsection setup by the cooling section of electric furnace gasification cooling flue so that flue from import to
The position (i.e. high-temperature area) that inner side extends to arc top is relatively independent, can process at short notice after it breaks down, and can
Damageable zone is changed in time, maintenance load and maintenance cost is reduced.
2nd, the cooling water pipeline in the utility model is optimised, and the leading portion of cooling section, back segment are carried out individually with water circulation,
Circulated into short distance single group by over long distances multigroup loop optimization so that its cooling effect ensured, extend the use of flue
Life-span.
