Abstract
The utility model discloses an air box pulse bag filter which comprises a casing, a filter bag and an ash bucket; wherein dust chambers are arranged on the two sides in the casing, an upper tube sheet is arranged at the upper part of the dust chambers, the upper end of the filter bag is fixed on the upper tube sheet, the space between the dust chambers on the two sides is divided into an upper chamber and a lower chamber by a sloping plate positioned in the middle, the lower chamber is the air inlet chamber which is connected with the air inlet on the front end surface of the casing, and the upper chamber is the air outlet chamber which is connected with the air outlet on the rear end surface of the casing; the air box pulse bag filter also comprises a flow distribution device comprising a main flow distribution plate and an auxiliary flow distribution plate, the main flow distribution plate is an arched plate and fixed under the bottom ends of the two sides of the air inlet chamber, and the auxiliary flow distribution plate is positioned between the main flow distribution plate. The air box pulse bag filter has the advantage of high filtering efficiency.
Description
Technical field
The utility model relates to a kind of deduster, especially a kind of air box impulse bag-type dust remover.
Background technology
Existing a kind of air box impulse bag-type dust remover contains housing, filter bag, ash bucket, soot cleaning system.The enclosure interior both sides are dirt pocket, and the internal upper part of housing is provided with upper face plate, and the upper end of filter bag is fixed on upper face plate, and the top of upper face plate is an exhaust chamber.Space between the enclosure interior dirt pocket makes this space become upper and lower two Room by the swash plate at middle part.Following chamber is that the air inlet of inlet plenum, this chamber and housing front end face links, and last chamber is a discharge chamber, and the air outlet of this chamber and housing rear end face links.Ash bucket is fixed on the bottom of housing, and soot cleaning system is positioned at the top of housing.During work, after dusty gas enters inlet plenum from air inlet, move downward enter ash bucket bottom and collide with it from inlet plenum after, change in the dirt pocket that its direction of motion enters the enclosure interior both sides, dust detention in the dusty gas that moves upward is purified dusty gas in the filter bag outside.Purified gas enters exhaust chamber through upper face plate in filter bag, discharged from air outlet by exhaust blower from discharge chamber again.Owing to be positioned at the dusty gas of bottom, inlet plenum both sides, after leaving inlet plenum, directly move upward because of short circuit, the dust content of the dusty gas of this part is higher, therefore near the filter bag load making outside the inlet plenum both sides strengthens, thereby cause each filter bag load inhomogeneous, this has reduced the efficiency of dust collection of deduster.
The utility model content
The technical problems to be solved in the utility model provides the high air box impulse bag-type dust remover of a kind of efficiency of dust collection.
For solving the problems of the technologies described above, a kind of air box impulse bag-type dust remover of the utility model, it contains housing, filter bag, ash bucket, the both sides, inside of housing are dirt pocket, the top of dirt pocket chamber is provided with upper face plate, the upper end of filter bag is fixed on the upper face plate, space between the dirt pocket of both sides, make on this part one-tenth by the swash plate that is positioned at the middle part, following two Room, following chamber is an inlet plenum, the air inlet of this chamber and housing front end face links, last chamber is a discharge chamber, and the air outlet of this chamber and housing rear end face links, and also contains part flow arrangement, this device is made of main flow distribution plate and secondary flow distribution plate, main flow distribution plate is an arc, and main flow distribution plate is fixed on the below of bottom, described inlet plenum both sides, and secondary flow distribution plate is between main flow distribution plate.
Owing to below inlet plenum, be provided with part flow arrangement, this makes the dusty gas of bottom in the inlet plenum both sides be forced through space between the main flow distribution plate of part flow arrangement, secondary flow distribution plate and the ash bucket conical surface, therefore the granule dust in this part dusty gas and the ash bucket conical surface collide, lose kinetic energy and stay bottom the ash bucket, dusty gas concentration is reduced, this has overcome the prior art dusty gas makes near the filter bag load the inlet plenum strengthen because of short circuit directly moves upward deficiency, thereby make the load of each filter bag even, this has improved the efficiency of dust collection of deduster.
Description of drawings
Accompanying drawing is the structural representation of the utility model air box impulse bag-type dust remover.
1. supports among the figure, 2. discharge chamber, 3. ash bucket, 4. main flow distribution plate, 5. secondary flow distribution plate, 6. housing, 7. inlet plenum, 8. exhaust chamber, 9. dirt pocket, 10. filter bag, 11. soot cleaning systems, 12. nozzles.
The specific embodiment
In the accompanying drawing, air box impulse bag-type dust remover contains housing 6, filter bag 10, ash bucket 3 and soot cleaning system 11.Housing 6 is fixed on the support 1, and the both sides, inside of housing 6 are dirt pocket 9, and its top is provided with upper face plate, and the upper end of filter bag 10 is fixed on the upper face plate, and the top of upper face plate is an exhaust chamber 8.Space between both sides, the inside dirt pocket 9 of housing 6, make this part become upper and lower two Room by the swash plate that is positioned at the middle part, following chamber is that the air inlet of inlet plenum 7, this chamber and housing 6 front end faces links, last chamber is a discharge chamber 2, the air outlet of this chamber and housing 6 rear end faces links, and ash bucket 3 is fixed on the bottom of housing 6.Top, its nozzle 12 that soot cleaning system 11 is positioned at housing 6 is positioned at filter bag 10 top suitable for reading.Air box impulse bag-type dust remover also contains part flow arrangement, and this device is made of main flow distribution plate 4 and secondary shunting 5 plates, and main flow distribution plate 4 is an arc, and main flow distribution plate 4 is fixed on the below of bottom, inlet plenum 7 both sides, and secondary flow distribution plate 5 is fixed between the main flow distribution plate 4.During work, dusty gas enters in the inlet plenum 7 from air inlet, flow down at the main flow distribution plate 4 of part flow arrangement and the branch of secondary shunting 5, dusty gas enters in the ash bucket 3 and changes the direction of motion and move upward with the back that collides, the bottom of ash bucket 3 from inlet plenum 7, enter in the dirt pocket 9 of housing 6 inner both sides, dust detention in the dusty gas that moves upward is in the outside of filter bag 10, and dusty gas is purified.Purified gas enters exhaust chamber 8 through upper face plate in filter bag 10, discharged from air outlet by exhaust blower from discharge chamber 2 again.After the running resistance of deduster is increased to certain value, soot cleaning system 11 work, compressed air makes the filter bag 10 that shriveled originally expand distortion in nozzle 12 spirt filter bags 10, dispose the dust that filter bag 10 outer surfaces adhere to, the dust under falls in the ash bucket 3 clearly.
