A kind of bag-type dust collector
Technical field
The utility model relates to industrial dedusting field, especially a kind of bag-type dust collector.
Background technique
Bag-type dust collector is a kind of dry dust removal apparatus, it is suitable for trapping tiny, dry non-fiber dust.Cloth
Bag using weaving filter cloth or nonwoven felt at, dusty gas is filtered using the filtration of fabric, when
Dusty gas enters bag filter, and particle is big, heavy dust since the effect of gravity settles down falls into ash bucket,
For gas containing relatively fine dust when passing through filtrate, dust is purified gas by detention.
When bag-type dust collector is filtered exhaust gas, the moisture contained in exhaust gas be easy to cause cloth bag outer surface initial
Dust layer condenses, is hardened, so as to cause cloth bag blocking.Some bag-type dust collectors are provided with heating device in ontology, still
It is excessively high to will lead to the temperature that cloth bag is born in this way, cloth bag curing shrinkage even generates broken hole.
The surface area of bag-type dust collector cloth bag is one of key index of dust removal performance, existing bag-type dust collector
Dust-removal cloth-bag surface is generally not provided with fold, causes cloth bag surface product smaller, efficiency of dust collection is low.
Generally be not provided with gas distributor in existing bag-type dust collector, exhaust gas from air inlet pipe enter ontology after cannot be equal
Even distribution, the filtering load for causing each dust-removal cloth-bag to be received is unequal, and the biggish cloth bag of Partial filtration load easily damages
It is bad.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of bag-type dust collectors, and it is easy to solve bag-type dust collector
Blocking, the problem of efficiency of dust collection is low and the biggish cloth bag of Partial filtration load is easily damaged.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of bag-type dust collector, including ontology,
Air inlet pipe and an air outlet pipe is set on the ontology, and silicon rubber heating tape, the silicon rubber heating is arranged in the air inlet tube outer surface
Band is connect with external power supply, and insulation board is arranged in the ontology and escape pipe outer gap, between the insulation board and body housing
Vacuum heat-insulating layer is set, dust-removal cloth-bag is set in the ontology, the dust-removal cloth-bag is cylindrical-shaped structure, and longitudinal section side is set
Set multiple outwardly projecting first circular arcs, circumferentially arranged multiple outwardly projecting second circular arcs in cross section, under dust-removal cloth-bag
Side's setting gas distribution guide plate, the periphery and inner body wall of the gas distribution guide plate are affixed, on gas distribution guide plate
It is uniformly arranged multiple through-holes.
Further, the insulation board is polyurethane foam board.
Further, the quantity of the dust-removal cloth-bag is four.
Further, the through-hole is circle.
Further, cone is arranged in the cup body lower part, and ash bucket is arranged in the bottom of cone.
Further, the dust-removal cloth-bag spaced set.
The utility model has the following beneficial effects:
1, since silicon rubber heating tape is arranged in the outer surface of tube wall of air inlet pipe and is arranged outside ontology and escape pipe
Insulation board and vacuum heat-insulating layer, rather than heating device is directly set in ontology, so can either go to contain in removing exhaust gas
Moisture, and not will lead to the excessively high appearance of cloth bag bearing temperature and shrink even broken hole.
2, due to the horizontal and vertical fold for being provided with arc-shaped protrusion in cloth bag outer surface, so the table of cloth bag
Area is greater than the surface area for being not provided with the common cloth bag of protrusion, and cloth bag surface product is larger, and efficiency of dust collection is higher.
3, due to being provided with distribution device in gas-fluid in ontology, so exhaust gas can uniformly divide after entering ontology from air inlet pipe
Cloth, the filtering load that each dust-removal cloth-bag is received is more balanced, not will lead to part cloth bag and is damaged since load is larger.

Specific embodiment
As shown in Fig. 1,2,3 and 4,2 He of air inlet pipe is arranged on the ontology 1 in a kind of bag-type dust collector, including ontology 1
Silicon rubber heating tape 21 is arranged in escape pipe 3,2 outer surface of air inlet pipe, and the silicon rubber heating tape 21 is connect with external power supply,
Insulation board 7 is arranged in the ontology 1 and 3 outer gap of escape pipe, and vacuum heat-preserving is arranged between 1 shell of the insulation board 7 and ontology
Layer 8, is arranged dust-removal cloth-bag 4 in the ontology 1, and the dust-removal cloth-bag 4 is cylindrical-shaped structure, the setting of longitudinal section side it is multiple to
Outer first circular arc 41 outstanding, circumferentially arranged multiple outwardly projecting second circular arcs 42 in cross section are set below dust-removal cloth-bag 4
Gas distribution guide plate 5 is set, the periphery and 1 inner wall of ontology of the gas distribution guide plate 5 are affixed, on gas distribution guide plate 5
It is uniformly arranged multiple through-holes 51.The insulation board 7 is polyurethane foam board.The quantity of the dust-removal cloth-bag 4 is four.It is described logical
Hole 51 is circle.Cone 6 is arranged in 1 lower part of cup body, and ash bucket 61 is arranged in the bottom of cone 6.The dust-removal cloth-bag 4 is equidistantly set
It sets.
When using the utility model dedusting, exhaust gas enters from air inlet pipe 2, and silicon rubber heating tape 21 adds exhaust gas
Moisture in exhaust gas is flashed to vapor by heat, after exhaust gas enters ontology, since the heat preservation of insulation board 7 and vacuum heat-insulating layer 8 is made
With vapor will not liquefy, and then pass through dust-removal cloth-bag 4 and be discharged from escape pipe 3, due to not directly setting heating in ontology 1
Device, so not will lead to the excessively high appearance of 4 bearing temperature of dust-removal cloth-bag shrinks even broken hole.
After exhaust gas is from air inlet pipe 2 into ontology, due to being provided with gas distribution guide plate 5 and gas below dust-removal cloth-bag 4
Multiple through-holes 51 are uniformly arranged on body distribution guide plate 5, so exhaust gas can be uniformly distributed after entering ontology from air inlet pipe 2, often
The filtering load that a dust-removal cloth-bag 4 is received is more balanced, not will lead to part cloth bag 4 and is damaged since load is larger.
Since the vertical and horizontal in 4 outer surface of dust-removal cloth-bag are provided with outwardly projecting first circular arc 41 and the second circle
Arc 42, so the surface area of dust-removal cloth-bag 4 is greater than the surface area for being not provided with the common cloth bag of protrusion, efficiency of dust collection is higher.
