Abstract
The invention relates to a blast-furnace gas dry-method dust remover which comprises a dust removing box body, wherein two sides of the top of the dust removing box body are provided with coal gas inlets, tail parts of the coal gas inlets are connected with a separator in a dust removing device, the bottom of the separator is provided with an enlarging hole, the dust removing box body is separated into a cyclone chamber, a dust removing chamber and an ash hopper chamber, the cyclone chamber and the dust removing chamber are separated by an upper baffle plate fixed in the dust removing box body, the dust removing chamber and the ash hopper chamber by a lower baffle plate fixed in the dust removing box body, a plurality of guide plates are uniformly distributed aslant in the cyclone chamber, the side surface of the dust removing chamber is provided with a pure coal gas outlet, a plurality of filter tubes are fixedly arranged in the dust removing chamber, the bottom of the ash hopper chamber is provided with a reflection cone body, and two sides of the bottom of the ash hopper chamber are provided with ash discharging holes. The blast-furnace gas dry-method dust remover has the advantages of reasonable design, small occupation area and good dust removing effect.
Description
Technical field
The present invention relates to a kind of cleaning apparatus, relate in particular to a kind of blast furnace gas nonaqueous dust cleaner.
Background technology
The dust metallurgical, that chemical industry produces can polluted air, influence people's quality of life, though dust has carried out certain purification before discharging; Carrying out dust separating device at present has gravitational precipitator, tornado dust collector and sack cleaner, and floor space is big, and efficiency of dust collection is higher; Floor space is little, and efficiency of dust collection is general, and blast furnace gas is through gravitational dust collection; The dust natural subsidence that particle is big falls into ash bucket, and fine dusts rises with coal gas; Dust is delayed at the outside surface of filter bag, and coal gas gets into filter bag, and the coal gas after the purification exports away from purified gas.This traditional structure mainly is that filter bag is playing the dedusting effect, and efficiency of dust collection is low.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 blast furnace gas nonaqueous dust cleaner comprises dust-removing box, and both sides, said dust-removing box top are provided with gas inlet; Said gas inlet afterbody is connected with the interior separator of cleaning apparatus; Said separator bottom is provided with extension mouth, and said dust-removing box is divided into spin chamber, dust settling chamber and grey small room, separates through being fixed in the intravital upper spacer of dust cleaning case between said spin chamber and the dust settling chamber; Separate through being fixed in the intravital lower clapboard of dust cleaning case between said dust settling chamber and the grey small room; Said spin chamber tilt is provided with even a plurality of flow deflector, and said dust settling chamber side has the purified gas outlet, and said dust settling chamber internal fixing has a plurality of strainer tubes; Said grey small room bottom is provided with the reflection cone, and said grey small room two bottom sides has ash discharging hole.
The pitch angle of said flow deflector and upper spacer horizontal plane is 20-60 °.
Said flow deflector is 10-20.
Said strainer tube is 30-50.
Advantage of the present invention: reasonable in design, floor space is little, good dedusting effect.

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, the spin chamber, 5, dust settling chamber; 6, grey small room, 7, separator, 8, extension mouth, 9, flow deflector, 10, the reflection cone; 11, upper spacer, 12, lower clapboard, 13, strainer tube, 14, ash discharging hole.
Embodiment
As shown in Figure 1, a kind of blast furnace gas nonaqueous dust cleaner of the present invention comprises dust-removing box 1; Both sides, dust-removing box 1 top are provided with gas inlet 2, and gas inlet 2 afterbodys are connected with cleaning apparatus 1 interior separator 7, and separator 7 bottoms are provided with extension mouth 8; Dust-removing box 1 is divided into spin chamber 4, dust settling chamber 5 and grey small room 6, separates through the upper spacer 11 that is fixed in the dust-removing box 1 between spin chamber 4 and the dust settling chamber 5, separates through the lower clapboard 12 that is fixed in the dust-removing box 1 between dust settling chamber 5 and the grey small room 6; Spin chamber's 4 tilt are provided with an even 10-20 flow deflector 9; Flow deflector 9 is 20-60 ° with the pitch angle of upper spacer 11 horizontal planes, and dust settling chamber 5 sides have purified gas outlet 3, and dust settling chamber 5 internal fixing have 30-50 strainer tube 13; Ash small room 6 bottoms are provided with reflection cone 10, and grey small room 6 two bottom sides have ash discharging hole 14.
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, the setting of flow deflector 9 in the spin chamber 4; Reduced the resistance of air-flow and decreased and impact, made air-flow have tangential velocity, made under the gentle flow direction of dust and move; Strainer tube 13 through dust settling chamber 5 filters, and reaches the effect that purifies coal gas, the setting of the reverse cone 10 in the grey small room 6; Directing air flow moves upward, and discharges through purified gas outlet 3, and dust is discharged from ash discharging hole 14.
Claims (4)
1. a blast furnace gas nonaqueous dust cleaner comprises dust-removing box, it is characterized in that: both sides, said dust-removing box top are provided with gas inlet; Said gas inlet afterbody is connected with the interior separator of cleaning apparatus; Said separator bottom is provided with extension mouth, and said dust-removing box is divided into spin chamber, dust settling chamber and grey small room, separates through being fixed in the intravital upper spacer of dust cleaning case between said spin chamber and the dust settling chamber; Separate through being fixed in the intravital lower clapboard of dust cleaning case between said dust settling chamber and the grey small room; Said spin chamber tilt is provided with even a plurality of flow deflector, and said dust settling chamber side has the purified gas outlet, and said dust settling chamber internal fixing has a plurality of strainer tubes; Said grey small room bottom is provided with the reflection cone, and said grey small room two bottom sides has ash discharging hole.
