Abstract
The utility model relates to a kind of blast furnace fast cooling furnace apparatus.The pipe nipple of blast furnace is communicated with blowpipe sealing, and sealing is fixed with air port peephole, the fixed nitrogen valve of air port peephole external seal on the pipe nipple, and nitrogen valve is communicated with the pipe nipple.Its structure is simple, and coke extinguishes fastly, and cool furnace speed is fast, meets environmental requirement.
Description
Technical field
The utility model relates to a kind of cool furnace apparatus, in particular to the fast cooling furnace apparatus of a kind of blast furnace.
Background technique
As ring Jing-jin-ji region environmental protection pressure increases, winter enters after Heating Season.Blast furnace will carry out cold stoking halt production.It is high at present
Furnace blowing out all uses safer completion method blowing out, and (coke substitutional load material of fetching water, coke is clawed, fill when blow-on again
Expect blow-on).The big heat of amount of coke is more in blast furnace after such method blowing out.It is long by the naturally cool furnace time.But pass through traditional furnace roof
It fetches water and forces to cool down, the bad control of the amount of fetching water, it is poor to beat few effect, beats the multipair refractory furnace bottom service life and has an impact, and also causes sky
Gas pollution.
Summary of the invention
The shortcomings that in order to overcome the prior art, the utility model provide a kind of blast furnace fast cooling furnace apparatus.Its structure is simple,
Coke extinguishes fastly, and cool furnace speed is fast, meets environmental requirement.
The technical solution adopted by the utility model to solve its technical problems is that: the pipe nipple of blast furnace is communicated with blowpipe sealing,
Sealing is fixed with air port peephole, the fixed nitrogen valve of air port peephole external seal, nitrogen valve and the pipe nipple phase on the pipe nipple
It is logical.
The utility model structure is simple, and coke extinguishes fastly, and cool furnace speed is fast, meets environmental requirement.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is utility model diagram.
Specific embodiment
As shown in Figure 1, the pipe nipple 3 of blast furnace (being not drawn into figure) is communicated with the sealing of blowpipe 1, sealed on the pipe nipple 3 solid
Surely there are air port peephole 4, the fixed nitrogen valve 5 of 4 external seal of air port peephole, nitrogen valve 5 is communicated with the pipe nipple 3.
Fixed valve 2 is sealed between the pipe nipple 3 and blowpipe 1.
The valve 2 is gate valve.
The valve 2 is blind plate device.
After blowing out damping down, valve 2 is closed, low temperature nitrogen is sealed by one, sebific duct interval air port peephole 4 with nitrogen valve 5
Gu nitrogen pressure 1MPa.Blast furnace roof opens big diffusion valve, natural air exhaust.It can form a nothing before air port
Coke is forced to extinguish by oxygen environment.Gas can take away heat after being passed through nitrogen, realize fast cooling furnace.It fetches water cool furnace with tradition
Mode is compared to more scientific, safe and environment-friendly.
