Description
Technical field
The present invention relates to a kind of cleaning apparatus, relate in particular to a kind of dedusting of blast furnace gas device.
Background technology
At present, the blast furnace gas that blast furnace ironmaking produces has good use value, and blast furnace gas is through gravitational dust collection; The dust natural subsidence that particle is big; Ash bucket in the middle of falling into, fine dusts rises with coal gas, and dust is delayed at the outside surface of filter bag; Coal gas gets into filter bag, and the coal gas after the purification exports away from purified gas.Coal gas in original technology has only passed through the one-time dedusting of equipment, contains more dust in this blast furnace gas, has only dust is reduced to 5-10mg/m
3Below could supply the user to use.Therefore, need provide a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide the high dedusting of blast furnace gas device of a kind of purifying and dedusting rate.
The technical scheme that the present invention adopts is:
A kind of dedusting of blast furnace gas device comprises dust-removing box, is located at the gas inlet at dust-removing box top and is located at the one lateral purified gas outlet of dust-removing box top that another side, said dust-removing box top has diffuses mouth and nitrogen inlet; In said gas inlet and the purified gas outlet leaf plate is installed all, said gas inlet lower end is connected with the intravital separator of dust cleaning case, and said separator bottom is provided with extension mouth; The dust-removing box internal fixing of said extension mouth top has lower clapboard; The dust-removing box internal fixing of below, said purified gas exit has screen cloth, and said screen cloth below is fixed with upper spacer, is fixed with a plurality of filter bags between said upper spacer and the lower clapboard; Said dust-removing box bottom is middle grey small room; Grey small room below, said centre has ash output hole one time, and a said ash output hole is provided with unloading valve, and a said ash output hole is connected with transport pipe; Said transport pipe is connected with ash-storing bin; Said ash-storing bin bottom has cinder-discharging port, and grey small room side, said centre is connected with meticulous ash handling equipment through pipeline, and said pipeline is provided with by-pass valve control.
Said meticulous ash handling equipment comprises leaching pipe and leaching device, and said meticulous ash handling equipment bottom has the secondary ash output hole.
Said filter bag number is 30-100.
Advantage of the present invention: reasonable in design, service life of equipment is long, good dedusting effect.
Description of drawings
Fig. 1 is an internal structure synoptic diagram of the present invention.
Wherein: 1, dust-removing box, 2, gas inlet, 3, the purified gas outlet, 4, diffuse mouth, 5, nitrogen inlet; 6, leaf plate, 7, separator, 8, extension mouth, 9, the secondary ash output hole, 10, screen cloth; 11, upper spacer, 12, lower clapboard, 13, filter bag, 14, middle grey small room, 15, ash output holes; 16, unloading valve, 17, transport pipe, 18, ash-storing bin, 19, cinder-discharging port, 20, pipeline; 21, by-pass valve control, 22, meticulous ash handling equipment, 23, the leaching pipe, 24, the leaching device, 25, the gas flow determinator.
Embodiment
As shown in Figure 1, a kind of dedusting of blast furnace gas device of the present invention comprises dust-removing box 1, is located at the gas inlet 2 at dust-removing box 1 top and is located at dust-removing box 1 top, one lateral purified gas outlet 3; Another side, dust-removing box 1 top has diffuses mouth 4 and nitrogen inlet 5, and gas inlet 2 exports on 3 with purified gas leaf plate 6 all is installed, and gas inlet 2 lower ends are connected with dust-removing box 1 interior separator 7; Separator 7 bottoms are provided with extension mouth 8, and dust-removing box 1 internal fixing of extension mouth 8 tops has lower clapboard 12, and dust-removing box 1 internal fixing that purified gas exports below, 3 places has screen cloth 10; Screen cloth 10 belows are fixed with upper spacer 11; Be fixed with 30-100 filter bag 13 between upper spacer 11 and the lower clapboard 12, dust-removing box 1 bottom is middle grey small room 14, and middle grey small room 14 belows have ash output hole 15 one time; One time ash output hole 15 is provided with unloading valve 16; One time ash output hole 15 is connected with transport pipe 17, and transport pipe 17 is connected with ash-storing bin 18, and ash-storing bin 18 bottoms have cinder-discharging port 19; Middle grey small room 14 sides are connected with meticulous ash handling equipment 22 through pipeline 20; Pipeline 20 is provided with by-pass valve control 21, and meticulous ash handling equipment 22 comprises leaching pipe 23 and leaching device 24, and meticulous ash handling equipment 22 bottoms have secondary ash output hole 9.
The present invention is running like this: blast furnace gas enters in the separator 7 in the dust-removing box 1, and pressure reduces behind extension mouth 8, and coal gas reaches purification through filter bag 13 and screen cloth 10; The dust that particle is bigger passes through natural subsidence; Grey small room 14 in the middle of falling into reaches one-time dedusting and purifies, again through meticulous ash handling equipment 22; Blast furnace gas carries out final dusting through leaching pipe 23 and leaching device 24, and dust removal efficiency is high.When gas flow determinator 25 mensuration gas flow values are close to zero; The leaf plate 6 of gas inlet place is closed; Nitrogen gets in the dust-removing box 1 from nitrogen inlet, opens unloading valve 16, and dust is blown in the meticulous ash handling equipment 22; Discharge from the secondary ash output hole, the entrap bubble in the dust-removing box 1 is from diffusing mouthful 4 discharges again.
