Description

A kind of cooling section of electric furnace gasification cooling flue
Technical field
The present invention relates to the auxiliary equipment of a kind of electric furnace, be specifically related to the cooling section of a kind of electric furnace gasification cooling flue.
Background technology
The gasification cooling flue of electric furnace is to realize one of energy recovery and the green necessaries produced, and it is for by electricity The flue gas produced in stove steelmaking process cools down and reclaims.The most domestic gasification cooling flue is from the first paragraph of electric furnace side (i.e. cooling section) is an entirety, and such design have ignored the Temperature Distribution in flue, and flue extends to inner side from import The position on arc top is high-temperature area, and maximum temperature can reach 1300 DEG C, and following position is middle gentle low-temperature region, and 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, do not carry out independently considering to damageable zone, relatively reduce the service life of flue.
Summary of the invention
The present invention provides the cooling section of a kind of electric furnace gasification cooling flue so that the high-temperature area of flue is relatively independent, when It can process after breaking down at short notice, and can change damageable zone in time, reduces maintenance load and maintenance Cost.
Technical scheme is as follows:
The cooling section of a kind of electric furnace gasification cooling flue, including leading portion, back segment and flange, described leading portion and back segment pass through institute State Flange joint together, inside described leading portion, be arranged parallel to the water screen tube one that flue axis carries out extending, described back segment Inside is arranged parallel to the water screen tube two that flue axis carries out extending;Described 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;Described back segment passes through water inlet pipe two and follows The water inlet manifold of ring water pump connects, and is connected with the flue backwater rising main of drum by return pipe two;Water circulating pump passes through back Supply mains is connected with drum;Flow control valve one is set on water inlet pipe one, water inlet pipe two arranges flow control valve two.
The cooling section of described electric furnace gasification cooling flue, its preferred version is, described flange is by asbestos seal.
The cooling section of described electric furnace gasification cooling flue, its preferred version is, water inlet pipe one and the caliber of water inlet pipe two At least 150mm.
The cooling section of described electric furnace gasification cooling flue, its preferred version is, return pipe one and the caliber of return pipe two At least 200mm.
The cooling section of described electric furnace gasification cooling flue, its preferred version is, the caliber of return main is at least 300mm。
The cooling section of described electric furnace gasification cooling flue, its preferred version is, water screen tube one and water screen tube two Quantity is at least 108.
The invention have the benefit that
1, the present invention carries out subsection setup by the cooling section of electric furnace gasification cooling flue so that flue from import to inner side The position (i.e. high-temperature area) extending to arc top is relatively independent, can process at short notice after it breaks down, and can be to easily Damage position to change in time, reduce maintenance load and maintenance cost.
2, the cooling water pipeline in the present invention is optimised, and the leading portion of cooling section, back segment carry out independent water distribution circulation, by growing Distance many groups loop optimization becomes short distance list group to circulate so that its cooling effect is ensured, extends the service life of flue.
3, on the water inlet pipe one in the present invention, flow control valve one is set, water inlet pipe two arranges flow control valve two, side Just the distribution being circulated the water yield adjusts, it is possible to ensureing that the output of leading portion is suitably above the output of back segment, cooling effectiveness obtains To improve.
