Description
Technical field
The utility model is related to top gas purification tapping equipment, and the purpose is to reduce when blast furnace stops multiple wind process
Exhaust emission.
Background technology
Blast furnace is stopped multiple wind and referred to：In process of production, because of factors such as production, equipment, peripheral demands, it is desirable to which blast furnace stops life
Produce all operating process.Blast furnace stops multiple wind process furnace roof and can diffuse a large amount of black smokes of discharge causes severe contamination to environment.Over-emitting black exhaust
Main cause：When blast furnace is normally produced furnace pressure in 230KP or so furnace top pressures in 105KP or so.Air quantity is reduced to during damping down
Pressure 60KP or so when 400, pressure on top surface leads to steam in 30KP or so, operating procedure, furnace roof, opens one and diffuses, and cut-out coal gas leads to
Damping down behind road, furnace roof igniting.During damping down air is discharged to due to there is coal gas in malleation, stove by diffusing with a large amount of dust
In, severe contamination is caused to environment.And reflux journey during multiple wind is also in this way, a large amount of tobacco, black smoke can be discharged.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of improved blast furnace roof for above-mentioned prior art
Gas purification tapping equipment, reduces exhaust emission when blast furnace stops multiple wind process.
The technical scheme in the invention for solving the above technical problem is：A kind of blast furnace stops multiple wind furnace top gas purification row
Device is put, including is arranged on the coal gas tedge above blast-furnace body, bleeding valve, coal gas are installed in the top of coal gas tedge
Tedge connects coal gas down-comer, and the outlet connection gravitational precipitator of coal gas down-comer, other connect of the coal gas tedge has
Gas purification pipe, and Pneumatic butterfly valve is set in the entry position of gas purification pipe, Pneumatic butterfly valve is only normally opened in the damping down period, coal
The outlet of gas purification pipe is connected to the second deduster, and the top of the second deduster sets coal gas discharge tube after purification, and second removes
Dirt device bottom is shaped to collect gray area.
Preferably, the second deduster be sack cleaner, the flying dust in being easy to coming out coal gas from blast furnace out-spreading, impurity,
Residue is retained.
Preferably, the gas purification pipe is descending manner, allows coal gas fully swimmingly to enter gas purification pipe, and processing is filled
Point.
It is highly preferred that negative pressure air exhauster can be configured for gas purification pipe, the delay of coal gas is reduced, dead angle is overcome.
After damping down instruction is connected to.First air quantity is reduced to 40% or so of full blast, blast is down to 30% of full blast or so.Furnace roof
Logical steam ensures malleation in stove, and now Pneumatic butterfly valve is opened（Dust burdening in coal gas is filtered by bag-type dust, after gas purification
Directly enter air from the coal gas discharge tube of the second dust remover roof）, by gravitational dust collection stop valve, cut off gravitational precipitator
Bleeding valve is opened after coal gas processing system path afterwards, damping down.
After multiple wind instruction is connected to.Bleeding valve is closed, air quantity is added to 40% or so of full blast, the 30% of blast to full blast
Left and right, opens gravitational dust collection stop valve, allows coal gas processing system row after gravity depositing dust to be closed into path, now Pneumatic butterfly valve, steams
Vapour is closed, and blast furnace is normally produced.
Compared with prior art, the utility model has the advantage of：There is provided a kind of blast furnace gas purification tapping equipment,
Blast furnace stops the environmental pollution for avoiding black smoke, tobacco discharge from causing during multiple wind, meets the environmentally friendly production requirement of modern industry.
Brief description of the drawings
Fig. 1 is that existing blast furnace stops multiple wind stock gas tapping equipment；
Fig. 2 is that blast furnace of the present utility model stops multiple wind stock gas tapping equipment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
A kind of improved blast furnace stops multiple wind furnace top gas purification tapping equipment, including is arranged on the coal of the top of blast-furnace body 1
Bleeding valve 3 is installed at gas tedge 2, the top of coal gas tedge 2, and coal gas tedge 2 is connected under coal gas down-comer 4, coal gas
The outlet connection gravitational precipitator 5 of pipe 4 drops.Coal gas tedge 2 is connected in addition gas purification pipe 7, and in gas purification pipe 7
Entry position sets Pneumatic butterfly valve 6, and Pneumatic butterfly valve 6 is only normally opened in the damping down period, and the outlet of gas purification pipe 7 is connected to pocket type
Deduster 8, the top of sack cleaner 8 sets coal gas discharge tube 9 after purification, and the bottom of sack cleaner 8 is shaped to collect gray area
10。
In addition to the implementation, the utility model also includes other embodiment, all use equivalents or equivalent
The technical scheme of substitute mode formation, all should fall within the utility model scope of the claims.
