Description

The online flat bag deduster of secondary
Technical field
The utility model is a kind of dust separation device that is formed by the organic assembling of cyclone dust removal, two standalone features of bag-type dust, and it is mainly used in metallurgy, the dry method dust of industries such as cement.
Background technology
Flat bag deduster on the market is most of to design according to a kind of dedusting active force, and dust in flue gas is no matter size all born by filter bag, so the duty ratio of filter bag is bigger; And the air inlet of deduster is general directly facing to filter bag, and dust in flue gas is directly washed away filter bag, causes the service life of filter bag not long.In addition, during the deduster online ash removal, downward power exists simultaneously when power that makes progress during air-out and reverse gas cleaning, and the effect of online ash removal is bad.
Summary of the invention
The purpose of this utility model is to design the online flat bag deduster of a kind of secondary, and the load that has solved traditional flat bag deduster filter bag is big, and service life is length and the bad problem of online ash removal.
According to the technical scheme that the utility model provides, described flat bag deduster comprises superposed upper box, be arranged in the casing at middle part and be positioned at the ash bucket of bottom, it is characterized in that: blowback wind arm is set in upper box, on the wall of upper box air inlet is set; Some filter bags are set in middle casing, the whirlwind circle are set in the bottom of middle casing, described whirlwind circle be arranged in air inlet on the casing base wall be communicated with.
Back blowing machine is set on deduster, and the outlet of described back blowing machine utilizes pipeline to be communicated with blowback wind arm, on the blowback wind arm blowing mouth is set, and described blowing mouth is facing to the air outlet of described filter bag upper end.Described ash bucket is back taper, in the bottom of ash bucket unloading valve is set.The vertical section of described whirlwind circle is back taper, and the air intake direction of air inlet is along the tangential direction of whirlwind circle, and the outlet of whirlwind circle upper end is facing to filter bag.
Top at upper box is provided with top cover, is provided for driving the slew gear of blowback wind revolution of arm in the upper end of top cover.Joint portion at upper box and middle casing is provided with card, and several installing holes are set on described card, and the upper end of described filter bag is installed in the described installing hole.Joint portion at middle casing and ash bucket is provided with bearing, on the wall of middle lower box inspection manhole is set.
Advantage of the present utility model is: 1, compact conformation, level is combined: the dual mode organic assembling that flue gas is handled is an one, utilizes cyclone dust removal to handle as one-level, removes bulky grain in the flue gas, alleviates the load of filter bag in the two-stage dust removal significantly.2, the use of the fan-shaped flexible baffle of back blow port had both improved the blowback effect, had also reduced the power consumption of back blowing machine simultaneously.3, the sealing of the flange of filter bag is installed, and makes deduster not have air leakage phenomena, and the fixed form at two ends has also been avoided the friction between cloth bag.4, the processing of the one-level of air inlet, cyclone dust removal formula has avoided flue gas directly to wash away filter bag down, has prolonged the service life of filter bag.

The specific embodiment
Among the figure, 1, air outlet, 2, blowback wind arm, 3, slew gear, 4, top cover, 5, upper box, 6, middle casing, 7, inspection manhole, 8, air inlet, 9, unloading valve, 10, back blowing machine, 11, ash bucket, 12, bearing, 13, the whirlwind circle, 14, filter bag, 15, card.
As shown in the figure: described flat bag deduster comprises superposed upper box 5, be arranged in the casing 6 at middle part and be positioned at the ash bucket 11 of bottom, it is characterized in that: blowback wind arm 2 is set in upper box 5, air inlet 1 is set on the wall of upper box 5; Some filter bags 14 are set in middle casing 6, whirlwind circle 13 are set in the bottom of middle casing 6, described whirlwind circle 13 be arranged in air inlet 8 on casing 6 base wall be communicated with.
Back blowing machine 10 is set on deduster, and the outlet of described back blowing machine 10 utilizes pipeline to be communicated with blowback wind arm 2, on the blowback wind arm 2 blowing mouth is set, and described blowing mouth is facing to the air outlet of described filter bag 14 upper ends.
Described ash bucket 11 is back taper, in the bottom of ash bucket 11 unloading valve 9 is set.The vertical section of described whirlwind circle 13 is back taper, and the air intake direction of air inlet 8 is along the tangential direction of whirlwind circle 13, and the outlet of whirlwind circle 13 upper ends is facing to filter bag 14.
At the top of upper box 5 top cover 4 is set, is provided for driving blowback wind arm 2 rotating slew gears 3 in the upper end of top cover 4.Joint portion at upper box 5 and middle casing 6 is provided with card 15, on described card 15 several installing holes is set, and the upper end of described filter bag 14 is installed in the described installing hole.Joint portion at middle casing 6 and ash bucket 11 is provided with bearing 12, on the wall of middle casing 6 bottoms inspection manhole 7 is set.
Processed flue gas walking approach is followed successively by: enters from the air inlet 8 of deduster bottom, and cyclone dust removal, bag-type dust purifies the air outlet 1 that finishes by deduster top and discharges.
Be provided with whirlwind circle 13 in the deduster air inlet 8, processed flue gas at first enters the cyclone dust removal district of deduster, and flue gas is rotated down along whirlwind circle 13, and bulky grain falls into ash bucket 11 in action of centrifugal force, finishes primary dust removing.Avoid bulky grain directly to wash away filter bag 14, prolonged the service life of filter bag 14.Processed flue gas enters the bag-type dust district that is arranged in casing 6 again through diffusion, through being clouded in the filtration, purification of the filter bag 14 in the bag-type dust district, finishes two-stage dust removal.
