Abstract
The utility model relates to a cyclone pulse bag-type duster, which is mainly composed of an air purifying chamber (2), the cylinder body of the internal circle (5), the cylinder body of the external circle (8), and a conical cylinder body (10), wherein, the periphery of the lower part of the cylinder body of the internal circle (5) is fixedly connected with the cylinder body of the external circle (8); an airflow clamped passage (12) is formed between the cylinder body of the internal circle and the cylinder body of the external circle; the airflow with dust is firstly conducted with the first-stage dust collection of the centrifugal force in the airflow clamped passage, and the internal part of the cylinder body of the internal circle (5) is provided with a bag-type duster which can conduct the second-stage dust collection to the airflow with dust. And when the second-stage dust collection is conducted, the cyclone pulse bag-type duster filters the bag through pulsing and blowing and through adopting the high-pressure compressed air. Thus, in industrial and mining enterprises, the cyclone pulse bag-type duster can particularly obtain better dust collecting effects on processing the high-concentration mixed airflow in wood-processing enterprises.
Description
The utility model is a kind of whirlwind pulse bag type dust collector, belongs to the cleaner of environmental protection, particularly is suitable for the environmental protection cleaner of wood processing enterprise.
In wood processing enterprise, deduster commonly used has cyclone separator and sack cleaner etc.Cyclone separator mainly contains one-tenth such as inner cylinder body, exterior cylinder and conic tube, is exhaust outlet above the inner cylinder body, and air inlet pipe tangentially is equipped with on exterior cylinder top, and the conic tube bottom is a discharge gate.Its groundwork principle is: the mixed airflow that will contain particle enters in the exterior cylinder from air inlet pipe, dust-contained airflow rotates in cylindrical shell, deposit under the centrifugal action particle in the mixed airflow is separated from air, particle is fallen into the conic tube bottom, discharge from discharge gate, air then enters atmosphere from the exhaust outlet on inner cylinder body top.The characteristics that cyclone separator separates are big to particle, that quality is big particle separative efficiency height; To the powder shape particle of light weight, separative efficiency is just extremely low, and it is more difficult especially to separate the following dust of 10 μ m.But that its advantage is a cost simple in structure is low, to isolating big fragmentary material and mixed airflow concentration when higher, more suitable.
Rotary blowback sack cleaner is made up of last cylinder, middle cylinder, following conic tube and top rotation blowback mechanism (comprising back blowing machine and rotating mechanism) etc.Operation principle is that cylinder bottom tangential direction enters in the tube in the dust-laden mixed airflow edge, under certain centrifugal action, has a spot of particle to be separated, from the discharge gate discharge of conic tube down.Filter bag in remaining dust and the air warp in the cylinder filters, and air sees through filter bag and enters in the cylinder, enters atmosphere through exhaust outlet.The dust that is got off by the filter bag detention shakes dust fall through the blowback air-flow, and under the gravity effect, dust still enters down conic tube to discharge gate and discharges.But this deduster shortcoming is a mixed airflow enter middle cylinder body from inlet after, no certain moving line restriction causes the air-flow diffusion, and flow velocity reduces, centrifugal force is too little, the effect that separates particle is just little, mainly is still by filter bag to filter, so when separating the high mixed airflow of concentration, particle between the inner filter bag of middle cylinder body is easy to generate clogging, add blowback wind-force deficiency, can not in time remove the dust stratification on the filter bag, can cause the deduster cisco unity malfunction.
More than two major types dedusters.When the former worked, allowing to handle mixed airflow concentration can be higher, but there is the low shortcoming of efficiency of dust collection in the dust particle; When the latter works, to dust particle efficiency of dust collection height, can not be high but handle mixed airflow concentration.Because wood-working factory can produce a large amount of wooden waste garrulous material (sheet, strip, granular and Powdered) when having a lot of lathes to produce, in the strength dust exhaust apparatus, require deduster efficiency of dust collection height, generally want to reach＞50～120g/m to handling mixed airflow concentration simultaneously
3(dustiness 50～120g) in every cubic meter air is made dedusting usefulness otherwise just be not suitable for being used for wood processing enterprise.
The purpose of this utility model just provides a kind of energy operate as normal under the mixed airflow situation of high concentration that suits, and can remove wooden waste garrulous material and dust simultaneously, and can obtain the whirlwind pulse bag type dust collector of high efficiency of dust collection.
Below in conjunction with drawings and Examples the technical solution of the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Each label symbol is in the accompanying drawing: 1. 9. times access doors of access door 5. inner cylinder bodies, 6. filter bag 7. air inlet pipe, 8. exterior cylinders, 10. conic tubes, 11. discharge gates, 12. air-flow passageways on exhaust outlet 2. air-purifying chambers 3. pulse spraying equipments 4.
This whirlwind pulse bag type dust collector is affixed-air-purifying chamber (2) on inner cylinder body (5), there are a lot of passages to link between inner cylinder body and the air-purifying chamber, air-purifying chamber one side is equipped with exhaust outlet (1), opposite side is equipped with pulse spraying equipment (3), many group filter bags (6) are housed in inner cylinder body (5) cylindrical shell, also have access door (4) on the barrel of inner cylinder body top, inner cylinder body (5) Lower Half is peripherally equipped with an exterior cylinder (8), form an air-flow passageway (12) between the inside and outside circle cylindrical shell, inside and outside circle cylindrical shell top seals up with steel plate at the place of passing through mutually, the inside and outside circle cylindrical shell bottom place of passing through mutually is an opened type, air-flow can freedom upwards enter from the inner cylinder body bottom, air inlet pipe (7) tangentially is housed on the cylindrical shell of exterior cylinder top, also have down access door (9) on the exterior cylinder, exterior cylinder (a 8) bottom affixed conic tube (10), the conic tube bottom is discharge gate (11), all mutual UNICOM between inside and outside circle cylindrical shell and the conic tube.Be rotated down motion in the passageway when the dust-laden mixed airflow enters from air inlet pipe (7), particle is under action of centrifugal force, and the passageway in the middle of inside and outside cylinder moves downward, and falls in the conic tube to discharge gate (11) to discharge; Otherwise, because air and dust centrifugal force are less than the centrifugal force of particle, air and a spot of dust move downward walks around inner cylinder body (5) bottom, upwards enters the filter bag (6) of inner barrel, and purifying air after filter entered in the atmosphere by air-purifying chamber (2) to exhaust outlet (1).Air-purifying chamber side in addition is equipped with pulse spraying equipment (3), this device source of the gas is an air compressor, by pipeline and nozzle to filter bag by some cycles and the frequency compressed air of jetting, remove the dust stratification on the filter bag powerfully, this dust stratification also drops in the conic tube and from discharge gate and discharges.Can guarantee that like this filter bag has the good aeration performance, overcome the easy clogging of particle between other type bag-type duster filtering bag.
The advantage of the utility model cyclone pulse bag-type duster is: mixed airflow the inside and outside circle cylindrical shell it Between the air-flow passageway in through the whirlwind primary dust removing, at first remove bigger wooden waste garrulous material, after again through in Pulse bag type dust collector in the cylinder is made two-stage dust removal, removes fine dusts remaining in the air-flow, from And reach the purpose of the mixed airflow of processing preferably high concentration, improved widely of the present utility model Efficiency of dust collection.
