Description
Technical field
The present invention 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 the filter cloth or nonwoven felt of weaving at being filtered using the filtration of fabric to dusty gas, when containing
Dust and gas body enters bag filter, and particle is big, heavy dust falls into ash bucket, contain since the effect of gravity settles down
There is the gas of 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.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of bag-type dust collectors, and it is easily stifled to solve bag-type dust collector
Plug, the problem of efficiency of dust collection is low and the biggish cloth bag of Partial filtration load is easily damaged.
The technical solution adopted by the present invention to solve the technical problems is: a kind of bag-type dust collector, including ontology, described
Air inlet pipe and an air outlet pipe is set on ontology, the air inlet tube outer surface is arranged silicon rubber heating tape, the silicon rubber heating tape with
Insulation board is arranged in external power supply connection, the ontology and escape pipe outer gap, is arranged between the insulation board and body housing
Vacuum heat-insulating layer, the ontology is interior to be arranged dust-removal cloth-bag, and the dust-removal cloth-bag is cylindrical-shaped structure, and the setting of longitudinal section side is more
A outwardly projecting first circular arc, circumferentially arranged multiple outwardly projecting second circular arcs in cross section, dust-removal cloth-bag lower section are set
Gas distribution guide plate is set, the periphery and inner body wall of the gas distribution guide plate are affixed, on gas distribution guide plate uniformly
Multiple through-holes are set.
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 invention 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 heat preservation is arranged outside ontology and escape pipe
Plate and vacuum heat-insulating layer, rather than heating device is directly set in ontology, so the moisture contained in removing exhaust gas can either be removed,
It not will lead to the excessively high appearance of cloth bag bearing temperature again 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.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is gas distribution guide plate structural schematic diagram；
Fig. 3 is dust-removal cloth-bag front view；
Fig. 4 is dust-removal cloth-bag top view.
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 dedusting of the present invention, exhaust gas enters from air inlet pipe 2, and exhaust gas is heated in silicon rubber heating tape 21, will
Moisture in exhaust gas flashes to vapor, after exhaust gas enters ontology, due to the insulation effect of insulation board 7 and vacuum heat-insulating layer 8, water
Steam will not liquefy, and then pass through dust-removal cloth-bag 4 and be discharged from escape pipe 3, since heating device is not arranged in ontology 1 directly,
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.
The above described is only a preferred embodiment of the present invention, being not intended to limit the present invention in any form, appoint
What those skilled in the art, without departing from the scope of the present invention, when in the technology using the disclosure above
Hold the equivalent embodiment for being modified or being modified to equivalent variations, but without departing from the technical solutions of the present invention, according to
According to technical spirit of the invention, within the spirit and principles in the present invention, it is to the above embodiments it is any it is simple modification,
Equivalent replacement and improve etc., fall within the scope of protection of the technical scheme of the present invention within.
