Description
Technical field
The utility model relates to a kind of equipment that utilizes electric field to capture dust in the dusty gas, especially a kind of combined type cottrell.
Background technology
At present, the combined type cottrell has obtained to use widely in building materials industry, and domestic large and medium-sized cement plant nearly all adopts it to purify the ash-laden gas of rotary kiln.In recent years, in dryer, raw mill, cement grinding mill and chamotte cooler, also adopted the combined type cottrell more and more.The combined type cottrell generally is not suitable for handling the big gas of dust content, when being used in cement rotary kiln, dust content should＜80g/Nm
3When being used in dryer, dust content should＜50g/Nm
3Otherwise, need before the combined type cottrell, acquire pre-processing device to remove crude particle dust.This not only increases investment, but also requires certain space mounting equipment.Regular maintenance also makes production cost increase simultaneously.
The utility model content
The technical problems to be solved in the utility model provides a kind of combined type cottrell, and this deduster can make crude particle dust realize pre-separation effectively, and the concentration of the dusty gas that enters the dedusting electric field region is reduced greatly.
The technical scheme that its technical problem that solves the utility model adopts is: comprise housing, blast pipe, air outlet, central air hose, vibrator, corona electrode, ash bucket, ash-valve, equal flow cone, ash bucket is arranged on lower part of frame, the below of ash bucket is provided with ash-valve, central air hose is arranged on the interior central authorities of housing, be provided with corona electrode between the lateral surface of central air hose and the medial surface of housing, the top of housing be provided with blast pipe and with central air hose communications and liaison mutually, the top of housing also is provided with air outlet, the lateral surface of housing is provided with vibrator, the below of central air hose is provided with equal flow cone, also comprise and be provided with the break-in flow plug in the central air hose successively, following break-in flow plug, all the below of flow cone is provided with dust-laying taper, is provided with the bottom air distribution plate between the inner bottom part of housing and the central air hose outer bottom.
Owing to be provided with break-in flow plug, following break-in flow plug in the central air hose successively, when high-temperature flue gas passes through central air hose, after colliding, high-temperature flue gas and upper and lower break-in flow plug fall, crude particle dust in the flue gas is through repeatedly changing direction and whereabouts, collision back, collide with equal flow cone again, fall into ash bucket after losing kinetic energy, thereby the dust concentration in the high-temperature flue gas reduces greatly, make that crude particle dust obtains pre-separation in the high-temperature flue gas, the speed of high-temperature flue gas greatly reduces simultaneously.Owing to be provided with the bottom air distribution plate between the inner bottom part of housing and the central air hose outer bottom, the high-temperature flue gas that greatly reduces when dust concentration and speed is during by this air distribution plate, flue gas can enter the dedusting electric field region equably on the one hand, a part of dust in the flue gas and bottom air distribution plate are collided on the other hand, directly fall into ash bucket after losing kinetic energy, thereby the concentration of high-temperature flue gas is further reduced; Owing to below equal flow cone, be provided with dust-laying taper, after the dust that ash bucket raises up and its collision, lose kinetic energy and drop in the ash bucket, suppressed the rising of dust concentration.This deduster can make crude particle dust realize pre-separation effectively in sum, and the concentration of the dusty gas that enters the dedusting electric field region is reduced greatly.Therefore need before the combined type cottrell, not acquire pre-processing device to remove crude particle dust.This not only reduces investment outlay, nor takies space outerpace.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
1. air outlets in the accompanying drawing, 2. air inlet, 3. housing, 4. corona electrode, 5. blast pipe, 6. central air hose, 7. vibrator is 8. gone up the break-in flow plug, 9. descends the break-in flow plug, 10. equal flow cone, 11. bottom air distribution plates, 12. dust-laying tapers, 13. ash-valves, 14. ash buckets.
The specific embodiment
In the accompanying drawing, the bottom of housing 3 is provided with ash bucket 14, and the interior central authorities of housing 3 are provided with central air hose 6, the top of housing 3 is provided with blast pipe 5, one end of blast pipe 5 has air inlet 2, and the other end of blast pipe 5 and central air hose 6 be communications and liaison mutually, and the top of housing 3 also is provided with air outlet 1.Between the medial surface of housing 3 and central air hose 6 lateral surfaces, be provided with corona electrode 4.The internal upper part of ash bucket 14 is provided with equal flow cone 10, and the lower end of ash bucket 14 and ash-valve 13 link, and the lateral surface of ash bucket 14 is provided with vibrator.The lateral surface top of housing 3 is provided with vibrator 7, in order to improve the rapping effect, also can vibrator be set in the lateral surface bottom of housing 3.In order to make the combined type cottrell handle the big gas of dust content, in central air hose 6, be provided with break-in flow plug 8 and following break-in flow plug 9, upper and lower break-in flow plug is formed by a plurality of conical surfaces that differ in size.When the high temperature dust flue gas by air inlet 2 when blast pipe 5 enters central air hose 6, the high temperature dust flue gas from top to down, at first by last break-in flow plug 8, after the conical surface of high temperature dust flue gas and last break-in flow plug 8 collides, changing direction and speed slows down, after the conical surface of crude particle dust in the high temperature dust flue gas and last break-in flow plug 8 collides, lose the conical surface whereabouts of kinetic energy along last break-in flow plug 8, after colliding, the high-temperature flue gas of change direction and slow-down and central air hose 6 inwalls change direction once more, enter down break-in flow plug 9, coarse granule dirt in the high-temperature flue gas changes direction again after colliding with the conical surface of following break-in flow plug 9, speed slows down again, after the conical surface of crude particle dust in the high-temperature flue gas and following break-in flow plug 9 collides, lose the conical surface whereabouts of kinetic energy along following break-in flow plug 9; After another changes the high-temperature flue gas of direction and central air hose 6 medial surfaces and collides, change direction, collide at last, after the crude particle dust in the high-temperature flue gas loses kinetic energy, bottom entering along ash bucket 14 inwalls with ash bucket 14 inwalls with equal wind awl 10 back that collides.After high temperature dust gas repeatedly changed direction and collision, crude particle dust fell into ash bucket 14 after losing kinetic energy, and the dust content of high-temperature flue gas reduces greatly, and crude particle dust obtains pre-separation, and the speed of high-temperature flue gas reduces greatly simultaneously.For the high-temperature flue gas that concentration is reduced evenly enters the dedusting electric field region, between the inner bottom part of housing 3 and central air hose 6 outer bottoms, be provided with bottom air distribution plate 11, this air distribution plate contains some equally distributed passages, the high-temperature flue gas that greatly reduces when dust concentration and speed is during by this air distribution plate 11, flue gas can enter the dedusting electric field region equably on the one hand, a part of dust in the flue gas and bottom air distribution plate 11 are collided on the other hand, fall into ash bucket after losing kinetic energy.In order to prevent that dust raises up in the ash bucket 14 the high-temperature flue gas concentration that enters the dedusting electric field region is increased, below equal flow cone 10, be provided with dust-laying taper 12, when the dust in the ash bucket 14 raises up and after the collision of the conical surface of dust-laying taper 12, lose kinetic energy and drop in the ash bucket.
