Description
Technical field
The utility model relates to a kind of dust pelletizing systems, are a kind of pair of ultra-clean dust pelletizing systems of the novel OG 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.
OG dust pelletizing system is primary dedusting system, and conventional dedusting method has dry dust removal, wet dust removal and half dry type to remove
Dirt.Wherein wet dust removal is most conventional dedusting method, and 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-saving effect is good, but needs to carry out large-scale redevelopment to dust removal system for workshop, and the period is transformed
Long, system is unstable；Half dry type dedusting, which can improve, follows bad water band mud amount, but energy consumption is higher, and 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 ultra-clean dust pelletizing system of the novel OG of fixed converter gas.
What the purpose of this utility model was realized in：
A kind of ultra-clean dust pelletizing system of novel OG of converter gas, it includes converter, passes through Vaporizing cooling cigarette at the top of the converter
It is connected at the top of road and first grade scrubber, first grade scrubber is connected to secondary scrubber, the top of secondary scrubber and circumferential weld Wen
The top of pipe is connected, and the bottom of circular seam Venturi tube is connected with the side of ultra-clean dewatering dust, in ultra-clean dewatering dust
Between section be tube bank, tube bank the upper-lower section of ultra-clean dewatering dust is connected, and restrain outside be exposed to ultra-clean dehydration
Deduster, by external environment atmosphere to tube bank outer wall cooling, the top of ultra-clean dewatering dust and primary dedusting blower into
Air port is connected, and the air outlet of primary dedusting blower is by being passed through coal-gas recovering area, and first grade scrubber, two after water seal inverted valve
Grade scrubbing tower, ultra-clean dewatering dust bottom pass through and be connected at a negative-pressure water-sealing and wastewater collection.
The ultra-clean dust pelletizing system of the novel OG of the utility model converter gas has the following advantages that：
The ultra-clean dust pelletizing system of this novel OG of converter gas is by being transformed dry dust removal system, and with ultra-clean dehydration
Deduster replaces ultra-clean dewatering dust interlude with tube bank to substitute wet rotation dehydrator, and tube bank outer wall passes through the external world
Ambient air cools down, and improves cooling effect.Furthermore the coal gas after dedusting is passed through water seal inverted valve by primary dedusting blower
Coal-gas recovering area afterwards improves safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the ultra-clean dust pelletizing system of the novel OG of the utility model converter gas.
In figure：Converter 1, gasification cooling flue 2, first grade scrubber 3, secondary scrubber 4, circular seam Venturi tube 5, ultra-clean dehydration
Deduster 6, tube bank 7, external environment atmosphere 8, primary dedusting blower 9, water seal inverted valve 10, coal-gas recovering area 11, negative-pressure water-sealing
12,13 at wastewater collection.
Specific embodiment
Referring to Fig. 1, the utility model relates to a kind of ultra-clean dust pelletizing system of the novel OG of converter gas, including converter 1, described turn
By being connected at the top of gasification cooling flue 2 and first grade scrubber 3 at the top of furnace 1, first grade scrubber 3 is connected to secondary scrubber 4, and two
The top of grade scrubbing tower 4 is connected with the top of circular seam Venturi tube 5, the side of the bottom of circular seam Venturi tube 5 and ultra-clean dewatering dust 6
Face is connected, and the interlude of ultra-clean dewatering dust 6 is tube bank 7, and tube bank 7 connects the upper-lower section of ultra-clean dewatering dust 6
Come, and the outside of tube bank 7 is exposed to ultra-clean dewatering dust 6, passes through 8 pairs of external environment atmosphere 7 outer walls of tube bank and cool down.It is ultra-clean
The top of dewatering dust 6 is connected with the air inlet of primary dedusting blower 9, and the air outlet of primary dedusting blower 9 is inverse by water seal
Only it is passed through coal-gas recovering area 11 after valve 10, and first grade scrubber 3, secondary scrubber 4, the bottom of ultra-clean dewatering dust 6 are equal
It is connected to by a negative-pressure water-sealing 12 at wastewater collection 13.
The ultra-clean dust pelletizing system of this novel OG of converter gas is by being transformed dry dust removal system, and with ultra-clean dehydration
Deduster replaces ultra-clean dewatering dust interlude with tube bank to substitute wet rotation dehydrator, and tube bank outer wall passes through the external world
Ambient air cools down, and improves cooling effect.Furthermore the coal gas after dedusting is passed through water seal inverted valve by primary dedusting blower
Coal-gas recovering area afterwards improves safety.
