Abstract
The utility model provides a kind of blast furnace winter building construction temperature-raising device, at least 2 heating furnaces are set up by blast furnace, inside heating furnace is divided into two layers inside and outside, internal layer is combustion chamber, outer layer is hotair chamber, hot gas delivery pipe one end with shut-off valve connects hotair chamber, and the other end is interlinked by blast-furnace tuyere and blast furnace crucibe and furnace bottom, and hotair chamber is also connected to air blower；Bottom house air port hole is blocked with blanket simultaneously.The hot-air that the utility model will warm up 40 DEG C is persistently delivered in blast furnace crucibe and furnace bottom by air blower, and high in-furnace temperature is improved 5 DEG C or more, meets blast furnace inner furnace bottom, the cupola well winter building construction of resistance to material condition, guarantees construction quality.
Description
Technical field
The utility model belongs to ironmaking brickwork apparatus field more particularly to a kind of blast furnace winter building construction is filled with temperature raising
It sets.
Background technique
The technical conditions that blast furnace lining building construction requires are that in-furnace temperature is greater than 5 DEG C.North of china in winter blast furnace is built
When construction, if in-furnace temperature is too low, it will lead to the mortar between refractory brick and freeze and lose viscosity, seriously affect masonry matter
Amount, is not only not achieved construction reference requirement, but also hide some dangers for the life of the blast furnace.It therefore, must in blast furnace lining building construction
Insulation must be taken, blast furnace internal temperature is made to remain at 5 DEG C or more, just can be carried out building construction, and guarantees engineering matter
Amount.
Summary of the invention
The utility model is intended to provide one kind and can improve blast furnace crucibe, bottom temperature, it is made to meet the height for building and requiring
Furnace winter building construction temperature-raising device.
For this purpose, the technical solution that the utility model is taken are as follows:
A kind of blast furnace winter building construction temperature-raising device, including heating furnace, air blower, hot gas delivery pipe and shut-off valve；?
Set up at least 2 heating furnaces by blast furnace, heating furnace is divided into two layers inside and outside, and internal layer is combustion chamber, and outer layer is hotair chamber, is had
Hot gas delivery pipe one end of shut-off valve connects hotair chamber, and the other end is communicated by blast-furnace tuyere with blast furnace crucibe and furnace bottom
Even, hotair chamber is also connected to air blower.
The utility model has the following beneficial effects:
The utility model is continuously supplied to blast furnace crucibe and furnace bottom by the hot-air that air blower will warm up 40 DEG C or more
It is interior, high in-furnace temperature is improved to 5 DEG C or more, meets blast furnace inner furnace bottom, the cupola well winter building construction of resistance to material condition, guarantees to apply
Working medium amount solves the problems, such as not can guarantee construction quality requirement because winter blast furnace in-furnace temperature is too low.
Detailed description of the invention
Fig. 1 is the temperature-raising device schematic diagram that 2 sets of heating furnaces are arranged.
In figure: heating furnace 1, combustion chamber 2, hotair chamber 3, shut-off valve 4, hot gas delivery pipe 5, blast furnace 6, air blower 7.
Specific embodiment
The utility model blast furnace winter building construction temperature-raising device is by 4,2 heating furnace 1, shut-off valve hot gas delivery pipes 5
And air blower 7 is formed.4 heating furnaces 1 equidistantly are set up on 6 side of blast furnace, it is inside and outside two layers that heating furnace 1, which divides, and internal layer is burning
Room 2, outer layer are hotair chamber 3, and each hotair chamber 3 installs 2 hot gas delivery pipes 5, and the other end of hot gas delivery pipe 5 is logical
It crosses 6 air port of blast furnace to interlink with 6 cupola well of blast furnace and furnace bottom respectively, 2 shut-off valves 4, air is respectively housed in 2 hot gas delivery pipes 5
Heating room 3 is also connected to air blower 7.The lower part air port hole of blast furnace 6 is blocked with blanket simultaneously, to prevent heat loss.
In the coke combustion loaded in combustion chamber 2, by the air in hotair chamber 3 be heated to 40 DEG C with
On, air blower 7 continues the hot-air in hotair chamber 3 being sent into 6 cupola well of blast furnace and furnace bottom, blast furnace 6 by hot gas delivery pipe 5
This has certain insulating power as closed container, and 6 air port hole of blast furnace is blocked with blanket, avoids heat loss.
40 DEG C or more hot-airs are persistently conveyed by 4 heating furnaces 1, cupola well, bottom temperature in blast furnace can be increased to 5 DEG C or more, from
And meet masonry quality and construction reference requirement.
