Mouth pipe 5；Blast furnace gas bypass valve front tube 6 is picked out on blast furnace gas desulfurizing tower inlet tube 4, then is bypassed and adjusted by blast furnace gas
It saves valve 3 and connects pipe 7 after blast furnace gas bypass valve, pipe 7 and blast furnace gas dry type desulfurizing tower after blast furnace gas bypass valve
Outlet 5 connects.
The blast furnace gas temperature cooler 1, blast furnace gas dry type desulfurizing tower 2, blast furnace gas desulfurizing tower inlet tube 4, height
After producer gas dry-type desulfurizing tower outlet 5, blast furnace gas bypass valve front tube 6 and blast furnace gas bypass valve between pipe 7
Connection be all made of welding；Blast furnace gas bypass valve front tube 6, blast furnace gas bypass valve 3 and blast furnace gas bypass are adjusted
Flanged joint is used between pipe 7 after section valve.
Non-purified blast furnace gas introduces blast furnace gas temperature cooler 1 through pipeline from process upstream, successively passes through blast furnace
Gas temperature cooler 1 and blast furnace gas desulfurizing tower inlet tube 4, are divided into two paths here, pass through blast furnace during normal production
Coal gas dry-type desulfurizing tower 2, blast furnace gas dry type desulfurizing tower outlet 5, enter in next process flow；When blast furnace gas dry type
Desulfurizing tower production status adjust when, blast furnace gas by blast furnace gas bypass valve front tube 6, blast furnace gas bypass valve 3,
Enter and above-mentioned same next technique after pipe 7 and blast furnace gas dry type desulfurizing tower outlet 5 after blast furnace gas bypass valve
In process.
Utility model device fills desulfurizing agent in blast furnace gas dry type desulfurizing tower, when blast furnace gas passes through dry type desulfurizing
In tower, desulfurizing agent removes the sulfide in blast furnace gas, is deposited in desulfurizing agent, and clean blast furnace gas is de- from dry type
Sulphur tower comes out and is transported in next process flow；The cooling medium of blast furnace gas temperature cooler is atomized water, works as blast furnace coal
Atomized water enters in cooler when temperature degree is more than its setting value, meets with the blast furnace gas of overtemperature and is cooled to blast furnace gas
Set temperature.Coal gas bypass valve puts into operation reaching use condition, guarantees the normal safety in production of the device.
Blast furnace gas is important secondary energy sources in steel plant, and the sufficient recycle of full dose is to realize steel plant's green
There is sulfide in blast furnace gas due to the adjustment of current iron-smelting raw material technical conditions in economic essential important measures
Concentration increases substantially, while National Environmental Protection Agency has put into effect new steel plant's sulfide for the resolution of prevention and control of air pollution
Concentration discharge requirement, the sulfide purification for causing steel plant's blast furnace coal gas must take new reliable technical measures,
It can be only achieved national environmental protection index.
The utility model has the advantage of after above-mentioned apparatus, the sulfide in coal gas is had blast furnace gas
The removing of effect, and reach national environmental protection index stops in desulfurization, drives or when raw materials for production change, vulcanizes in blast furnace gas
When object concentration changes, bypass valve puts into operation.
Detailed description of the invention
Fig. 1 is the structural map of utility model device.Wherein, blast furnace gas temperature cooler 1, blast furnace gas dry type desulfurization
Tower 2, blast furnace gas bypass valve 3, blast furnace gas desulfurizing tower inlet tube 4, blast furnace gas dry type desulfurizing tower outlet 5, blast furnace
Pipe 7 after coal gas bypass valve front tube 6, blast furnace gas bypass valve.
