Abstract
The utility model discloses a vertical type electric-bag composite dust catcher which aims at solving the problems that dust charge is not sufficient for the prior electric-bag composite dust catcher, and the like. The vertical type electric-bag composite dust catcher adopts the technical proposal that an electrical dust removing plant (5) is arranged above an ash bucket (7), and a cloth-bag dust removing plant (2) is arranged above the electrical dust removing plant (5), thereby having the advantages of simple manufacture, sufficient charge, and the like.
Description
Affiliated technical field: the utility model relates to a kind of dust arrester of control atmosphere pollution, relates in particular to a kind of vertical electrostatic fabric filter of being made up of import smoke box, housing, outlet smoke box, ash bucket.
Background technology: Chinese patent CN2730484 discloses a kind of like this electric bag compound type dust remover, its design feature is: be made up of import smoke box, housing, outlet smoke box, ash bucket, be disposed with electric dust collector, flue gas flow equalizing device and bag-type dust collector near in the housing of import smoke box along airflow direction.Chinese patent CN2000951372 discloses a kind of like this electric bag compound type dust remover, it is made up of import smoke box, housing, outlet smoke box, ash bucket, in housing, be disposed with electric dust collector and bag-type dust collector along airflow direction, be provided with on the top of electric dust collector and can make airflow direction import smoke box vertically downward, between electric dust collector and bag-type dust collector, be provided with dividing plate.Its form is horizontal after adopting said structure, be that the flue gas level is introduced, in a horizontal electric field, purify and make dust charged, level feeds the bottom of bag field then, and air-flow is folded to vertical direction again and enters filter bag, therefore, air-flow is changed into vertical direction by horizontal direction and is easily caused certain drag losses, because the length of bag field is bigger, also causes dust in flow process, to make its carrying capacity loss easily, thereby influence dust removing effects again.
Summary of the invention: the purpose of this utility model provides and a kind ofly can reduce gas-flow resistance, again the multiple electrostatic fabric filters that the dust charge electric weight can not be reduced.
For achieving the above object, the technical solution of the utility model is: vertical electrostatic fabric filter, form by import smoke box, housing, outlet smoke box, ash bucket, be disposed with electric dust collector and bag-type dust collector near in the housing of import smoke box along airflow direction, above ash bucket, be provided with electric dust collector, above electric dust collector, be provided with bag-type dust collector.
Be provided with the import smoke box on ash bucket top, import smoke box and ash bucket should be processed into one.
After adopting this structure, owing to above electric dust collector, be provided with bag-type dust collector, the band dust flue gas enters electric dust collector harvest and charged through the import smoke box, have charged part dust flue gas and directly enter bag-type dust collector, it is loose in order that filter bag outer surface dust is arranged, the gap rate height, easy-to-clean ash has further reduced the equipment running resistance.
Description of drawings: the utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the main cross-sectional schematic of vertical electrostatic fabric filter.
Among the figure: 1, outlet smoke box; 2, cloth bag field dust arrester; 3, power supply; 4, housing; 5, electric dust collector; 6, import smoke box; 7, ash bucket; 8, positive plate rapping apparatus; 9, cathode rapping device.
The specific embodiment: shown in the accompanying drawing, the utility model vertical electrostatic fabric filter, form by import smoke box 6, housing 4, outlet smoke box 1, ash bucket 7, be disposed with electric dust collector 5 and bag-type dust collector 2 near in the housing 4 of import smoke box 6 along airflow direction, above ash bucket 7, be provided with electric dust collector 5, above electric dust collector 5, be provided with bag-type dust collector 2; Be provided with import smoke box 6 on ash bucket 7 tops, import smoke box 6 should be processed into one with ash bucket 7.
When vertical electrostatic fabric filter is in running order, ash-laden gas is introduced from ash bucket 7 sides through guide vane, upwards enter electric dust collector 5 again, be collected down at effect of electric field lower part dust, all the other dust are continued upwards to enter bag-type dust collector 2 by charged with flue gas, outside filtering type is adopted in the filtration of flue gas, and ash-laden gas is introduced from filter bag is outside, and dust is delayed at the filter bag outer surface.Pure gas is discharged the air-purifying chamber that enters top from the filter bag inner chamber, discharges from the left end gas outlet then.It is to realize by means of positive plate rapping apparatus 8 that dust on the positive plate is removed, and impacts the bottom trip rod and realizes that the removing of the dust stratification of corona discharge electrode also is to realize by means of the hammering of the cathode rapping device 9 at middle part.Power supply 3 can be installed on the inspection platform, and its port of export links to each other with the insulating sleeve top cover, and high voltage direct current just can be introduced the framework of corona electrode like this.One winding-up pipe is installed above every row's filter bag, and winding-up Guan Yiduan communicates with gas bag and pulse valve, and compressed air feeds in the gas bag, when pulse valve moment unlatching, one high pressure draught just sprays into filter bag from the aperture of winding-up pipe, and filter bag moment cripling just can be fallen by shake attached to the dust on filter bag surface.
Claims (2)
1, a kind of vertical electrostatic fabric filter, form by import smoke box, housing, outlet smoke box, ash bucket, be disposed with electric dust collector and bag-type dust collector near in the housing of import smoke box along airflow direction, it is characterized in that: be provided with electric dust collector (5) in ash bucket (7) top, be provided with bag-type dust collector (2) in electric dust collector (5) top.
2, vertical electrostatic fabric filter according to claim 1 is characterized in that: be provided with import smoke box (6) on ash bucket (7) top, import smoke box (6) should be processed into one with ash bucket (7).
