Description
Technical field
The utility model relates to electric precipitator technical field, refers in particular to a kind of deashing device adapting to the dedusting of steel-making dry method round type.
Background technology
In converter steelmaking production process, produce a large amount of flue gas containing CO, wherein with the solid particulate that ferric oxide, calcium oxide, silicon-dioxide, magnesium oxide and other composition are formed.Application converter flue gas dry cleaning and gas recovery system can flue with protection of the environment, the high heating value gas simultaneously receiving clean.
First the high-temperature flue gas produced in convertor steelmaking process is trapped by movable gas hood, then through gasification cooling flue, lowers the temperature for the first time while recovery heat energy to flue gas.General gasification cooling flue temperature out is about 800-1000 DEG C.Dry cleaning recovery system adopts transpiration-cooled mode to carry out the reducing temperature twice of flue gas, traps crude particle dust simultaneously.For meeting the temperature condition of electric precipitator work, outlet temperature for evaporation cooler general control is within the scope of 170 ~ 250 DEG C.Cooled flue gas enters electrostatic precipitator and carries out smart dedusting, house outlet dust contained flue gas concentration≤10mg/Nm
3.Waste gas between the non-blowing process then by diffusing a glass valve, directly diffuses after entering diffusing chimney.In converting process, because CO concentration in converter gas is constantly change, enter after the flue gas of the low CO content produced at Primary period and later stage is purified by electric precipitator and diffuse a glass valve, by diffusing chimney ignition bleeding.By recovery cup valve after the flue gas of the high CO content of blowing generation in mid-term enters fly-ash separator purification, enter gas cooler and reduce the temperature to less than 70 DEG C further, then send into gas chamber and store.Existing converter steelmaking coal gas dry method dust-remover deashing is not thorough, reduces the dust-collecting efficiency of electric precipitator, causes atmospheric pollution.
Summary of the invention
