The rotational flow device, composed of helical blades, is arranged on the upper part inside the air inlet pipe. The flow equalizing awl is positioned under the air inlet pipe and at the upper part inside the ash bucket. The flow equalizing awl is a cone. The casing is cylindrical. The dust remover can effectively lead ash-laden gas to enter each filter bags homogeneously, which raises the dust removing efficiency of the dust remover. The dust remover is widely applied in the industry of cement, building material, metallurgy, chemical industry, electric force, etc.

Description

The cylinder sack cleaner
Technical field
The utility model relates to a kind of equipment that utilizes filter bag to remove dust in the ash-laden gas, specifically, relates to a kind of cylinder sack cleaner.
Background technology
At present, sack cleaner is widely used in industries such as cement, building materials, metallurgy, chemical industry, electric power, the basic principle of this class deduster is, dusty gas enters air inlet pipe through flue, and the part crude particle dust is fallen into ash bucket by inertia, and the remainder exhaust gas dust enters filter bag, after the filter bag inner surface filters, dust is trapped on the inner surface of filter bag, and purified gas passes filter bag and enters air-purifying chamber, is discharged by blast pipe.Deduster is after operation a period of time, and the dust layer that the filter bag inner surface is caught thickens.The running resistance of deduster rises, and when being increased to certain value, must carry out deashing to the filter bag inner surface, and the running resistance of deduster is descended, when resistance drops to certain value, and normal operation input again.Deashing is mainly undertaken by blowback wind, when the resistance rising needs deashing, closes exhaust duct, opens blowback air-valve and back blowing machine, and the filter bag that expands is originally shriveled distortion under the blowback wind action, it is reached remove the purpose that the filter bag inner surface adheres to dust.Deashing falls into ash bucket, enters conveyer through ash-valve and discharges.Because the shape of this class deduster is generally body structure, it is very inhomogeneous that ash-laden gas enters filter bag, has a strong impact on the efficiency of dust collection of deduster.
The utility model content
To enter this class filter bag of dust collector inhomogeneous in order to overcome ash-laden gas, influences the deficiency of the efficiency of dust collection of deduster.The utility model provides a kind of cylinder sack cleaner, and this deduster can effectively make ash-laden gas enter each filter bag more equably, improves the efficiency of dust collection of deduster.
The technical scheme that its technical problem that solves the utility model adopts is: comprise blast pipe, air inlet pipe, back blowing machine, blowback air-valve, reverse-blow pipe, air-purifying chamber, upper face plate, filter bag, lower face plate, housing, ash bucket, ash-valve, the internal upper part that also comprises described air inlet pipe is provided with swirl-flow devices, swirl-flow devices is made of helical blade, the below of air inlet pipe be provided with equal flow cone and in ash bucket above, all flow cone is a cone, and described housing is columnar structured.
The helical blade of described swirl-flow devices is no less than four.
The beneficial effects of the utility model are, because the internal upper part in air inlet pipe is provided with swirl-flow devices, when ash-laden gas enters air inlet pipe through swirl-flow devices, after colliding, the dust granules in the ash-laden gas and the helical blade of swirl-flow devices glide to falling to colliding with equal flow cone again along this blade, fall in the ash bucket after losing kinetic energy, after meanwhile the helical blade of flue gas and swirl-flow devices collides, changing the direction of motion moves downward along helical blade and air inlet pipe medial surface spiral, enter ash bucket rotation and scatter until leaving air inlet pipe, because the below of air inlet pipe is provided with equal flow cone, a part is left the flue gas that air inlet pipe moves downward and can not be continued downwards, with equal flow cone collision, flue gas is evenly to diffusion everywhere, because housing is columnar structured, thereby can evenly enter filter bag, improve the efficiency of dust collection of deduster.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model cylinder sack cleaner structural representation.
Fig. 2 is that the utility model cylinder sack cleaner swirl-flow devices A is to enlarged drawing.
1. blast pipes among the figure, 2. air inlet pipe, 3. back blowing machine, 4. blowback air-valve, 5. reverse-blow pipe, 6. air-purifying chamber, 7. swirl-flow devices, 8. upper face plate, 9. filter bag, 10. lower face plate, 11. housings, 12. equal flow cones, 13. ash buckets, 14. supports, 15. ash-valves.
The specific embodiment
Among Fig. 1, housing 11 is columnar structured, air inlet pipe 2 is arranged on the central authorities of housing 11 and passes the top, the internal upper part of housing 11 is provided with air-purifying chamber 6, going to the bottom of air-purifying chamber 6 is upper face plate 8, and the interior bottom of housing 11 is provided with lower face plate 10, is provided with filter bag 9 between upper face plate 8 and lower face plate 10, the below of housing 11 is provided with ash bucket 13, and ash bucket 13 links with the ash-valve 15 of below.The top of housing 11 is provided with back blowing machine 3, blowback air-valve 4, reverse-blow pipe 5, and back blowing machine 3 links with blowback air-valve 4, blowback air-valve 4 links with reverse-blow pipe 5, reverse-blow pipe 5 links with air-purifying chamber 6.Blast pipe 1 is arranged on the top of housing 11 and links with air-purifying chamber 6.The internal upper part of air inlet pipe 2 is provided with swirl-flow devices 7, and swirl-flow devices 7 is made of the helical blade more than four.In order to make the flue gas that enters in the filter bag 9 even, the helical blade of swirl-flow devices 7 generally is no less than four, is generally six to eight.The below of air inlet pipe 2 is provided with equal flow cone 12, and all flow cone 12 is fixed on the internal upper part of ash bucket 13 by support 13.During work, ash-laden gas is entered by air inlet pipe 2, when by swirl-flow devices 7, after colliding, the helical blade of dust granules in the ash-laden gas and swirl-flow devices 7 glides to falling to colliding with equal flow cone 12 again along this blade, fall in the ash bucket 13 after losing kinetic energy, dust in flue gas concentration is reduced, and dust in flue gas obtains pre-separation.After the helical blade of flue gas and swirl-flow devices 7 collides, change the direction of motion and move downward, enter ash bucket 13 spirals and scatter until leaving air inlet pipe 2 along helical blade and air inlet pipe 2 medial surface spirals.Flue gas moves downward as spiral during this period, after the inwall of dust granules and air inlet pipe 2 collides in the flue gas, fall to colliding with equal flow cone 12 again along inwall, fall in the ash bucket 13 after losing kinetic energy, dust in flue gas concentration is further reduced, and makes dust in flue gas obtain pre-separation again.Because flue gas moves downward as spiral, consumed energy is big, speed greatly reduces when entering ash bucket 13, with equal flow cone 12 collisions, flue gas because housing 11 is columnar structured, thereby evenly enters filter bag 9 evenly to diffusion everywhere, because dust in flue gas obtains pre-separation, so the efficiency of dust collection of deduster is improved.
