Technical field
The utility model relates to a kind of dust pelletizing systems, are the ultra-clean dust pelletizing systems of separate type of a kind of pair of converter gas.
Background technique
Converter gas (converter fume and dust) refers to the brown dense smoke being discharged during bessemerizing, is
The mixture of furnace gas and flue dust, main component are CO, additionally contain a small amount of carbon dioxide and other micro high-temperature gases
And flue dust.Converter gas ingredient CO86%, CO210%, N23.5%, O20.5%；Temperature is 1400~1600 DEG C.Smoke content
In 80~150g/m3Its ingredient of range is shown in Table；About 10~20 μm of flue dust, be fine particle, it is difficult to separate.The temperature of flue gas is very
Height can waste many heats if not being used；And CO in furnace gas is as can recycling, and fuel and industrial chemicals well；
If flue dust is directly discharged in atmosphere, atmosphere can be caused seriously to pollute, if can be recycled, sinter or pelletizing is made
Mine is then good iron-smelting raw material.Therefore, the Recovery Purifying of converter gas has very big economic value.
Conventional dedusting method has dry dust removal, wet dust removal and half dry type dedusting.Wherein wet dust removal is most conventional
Dedusting method, the technology maturation of wet dust removal is stable, but dust removing effects are general；The high dust collection efficiency of dry dust removal, energy conservation
Effect is good, but needs to carry out dust removal system for workshop large-scale redevelopment, and the transformation period is long, and system is unstable；Half dry type dedusting can
Bad water band mud amount is followed to improve, but energy consumption is higher, system is unstable, and second half section equipment collects coal gas and natural gas is collected
It is divided into two-way progress, separating effect can be improved.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of high dust collection efficiencys, and energy-saving effect is good, and system is steady
The ultra-clean dust pelletizing system of the separate type of fixed converter gas.
What the purpose of this utility model was realized in：
A kind of ultra-clean dust pelletizing system of the separate type of converter gas, it includes converter, passes through Vaporizing cooling at the top of the converter
It is connected at the top of flue and wet cooling tower, the ash hole of wet cooling tower bottom is connected with conveyer, and cinder is sent to by conveyer
In cinder storehouse, the side of wet cooling tower is connected by pipeline with multiple bag filters, setting in the bag filter
There is purge valve, purge valve is connected by pipeline with gas tank, and bag filter bottom is connected with surge bunker, the bottom of surge bunker
Fine ash is sent in fine ash storehouse by portion by chain-linked conveyer, is drawn at the top of multiple bag filters by pipeline, is filled on the pipeline
There is detector, which is divided into two-way, it is connected all the way with scrubbing tower, the top of scrubbing tower and primary dedusting blower
Air inlet be connected, the air outlet of primary dedusting blower is by being passed through coal-gas recovering area, another way and axis stream after water seal inverted valve
The air inlet of blower is connected, and the air outlet of axial flow blower is connected with chimney, and chimney is connected with natural gas line.
The ultra-clean dust pelletizing system of the separate type of the utility model converter gas has the following advantages that：
The ultra-clean dust pelletizing system of the separate type of this converter gas is removed by being transformed to dry dust removal system with cloth bag
Dirt device substitutes electric precipitator, the factors of instability after electricity can be met to avoid oxygen in coal gas, and can avoid with on-bne repair
Air residual, bag filter lower section are additionally arranged surge bunker and chain-linked conveyer, fine ash preferably can be sent into fine ash storehouse.This
Coal gas after dedusting by coal-gas recovering area after water seal inverted valve, is improved safety, and later half by outer primary dedusting blower
Section equipment collects coal gas and natural gas collection is divided into two-way and carries out, and separating effect can be improved.
