Technical field
The utility model relates to a kind of dust pelletizing systems, are the dry dust removal systems 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.
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 dry dust removal system of fixed converter gas.
What the purpose of this utility model was realized in：
A kind of dry dust removal system of converter gas, it includes converter, at the top of the converter by gasification cooling flue with
Connection, the ash hole of wet cooling tower bottom are connected with conveyer at the top of wet cooling tower, and cinder is sent to cinder storehouse by conveyer
In, the side of wet cooling tower is connected by pipeline with multiple bag filters, and air blowing is provided in the bag filter
Valve, purge valve are connected by pipeline with gas tank, and bag filter bottom is connected with surge bunker, and the bottom of surge bunker passes through
Fine ash is sent in fine ash storehouse by chain-linked conveyer, is connected by pipeline with scrubbing tower at the top of multiple bag filters, scrubbing tower
Top be connected with the air inlet of primary dedusting blower, the air outlet of primary dedusting blower by after triple valve, a pipeline with
Chimney is connected, and chimney is connected with natural gas line, and another pipeline is by being passed through coal-gas recovering area after water seal inverted valve.
The dry dust removal system of the utility model converter gas has the following advantages that：
The dry dust removal system of this converter gas by being transformed to dry dust removal system, and with bag filter come
Electric precipitator is substituted, the factors of instability after electricity can be met to avoid oxygen in coal gas, and air can be avoided residual with on-bne repair
It stays, is additionally arranged surge bunker and chain-linked conveyer below bag filter, fine ash preferably can be sent into fine ash storehouse.Furthermore primary
Coal gas after dedusting by coal-gas recovering area after water seal inverted valve, is improved safety by dedusting fan.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the dry dust removal system of the utility model converter gas.
Fig. 2 is the schematic diagram of front half section equipment in Fig. 1.
Fig. 3 is the schematic diagram of second half section equipment in Fig. 1.
In figure：Converter 1, wet cooling tower 3, conveyer 4, cinder storehouse 5, bag filter 6, is blown at gasification cooling flue 2
