Description
Technical field
The utility model relates to deduster technical field more particularly to a kind of sedimentation dedusting devices of bag filter.
Background technique
Deduster is a kind of equipment that dust is separated from flue gas.It is existing a kind of to remove gravity settling chamber and pocket type
The combined duster that dirt device connects together.It is most ancient, most easy cleaner that gravitational settling, which stops up, mainly by chamber body, into
Port, gas outlet and flue-dust retainer composition.Dust-contained airflow enters in chamber body, drops gas flow rate because of the expansion of flow section
Low, larger grit is got off by self gravitation effect natural subsidence by separation and collection.For the dedusting effect for improving gravity settling chamber
Rate, some some vertical baffles of installation indoors, on the one hand in order to change the direction of motion of air-flow, since dust inertia is larger,
Direction cannot be changed together in company with gas, bumped against on baffle, lose the kinetic energy for continuing to fly upward, be deposited in following ash bucket；Separately
On the one hand in order to extend the passage distance of dust, it is made gradually to settle down under the effect of gravity.As shown, generating gas
Some shallow bids are vortexed, and grit is separated by centrifugal action with gas, and encounter on locular wall and on baffle, are allowed to settle down.
(dirt pocket is settled shown in referring to Fig.1)
Combined duster is to be arranged to connect between the net gas outlet of gravity settling chamber and the air inlet of sack cleaner
Pipe, dusty gas are further purified by sack cleaner again after gravity settling chamber preliminary purification.Due to gravity settling chamber and bag
Formula deduster is two independent equipment, and space occupied is big, and structure is complicated.
It is therefore desirable to be improved.
Utility model content
In view of the deficienciess of the prior art, that the purpose of this utility model is to provide a kind of space occupied is small, structure is simple
The sedimentation dedusting device of bag filter that is single, extending cloth bag service life.
To achieve the goals above, following technical solution is provided:
The sedimentation dedusting device of bag filter is provided with air inlet on shell of dust remover, which is characterized in that sedimentation dedusting
Device includes settling baffle and air guide member, and the inside of air inlet is arranged in settling baffle, and the outside of air inlet is arranged in air guide member,
Air guide member is an infundibulate cylinder, and the area of air inlet is less than the area of gas outlet.
Preferably, the settling baffle is fixed on the inside of air inlet by support rod.
Preferably, the air guide member is by rounded transitional to rectangular infundibulate cylinder, and the circular open of air guide member is
Inlet end, square aperture are outlet side, and the circular open area of air guide member is less than its square aperture area, and the rectangular of air guide member is opened
Mouth is arranged in air inlet.
Preferably, air inlet split-wind plate is equipped at the gas outlet of the air guide member, air inlet split-wind plate is equipped with several
Ventilation hole.
After adopting the above structure, the utility model is compared to the prior art advantageously: the utility model is removing
The air inlet of dirt device is provided with sedimentation dedusting device, is first settled to large dust particle using sedimentation dedusting device, reduces
Dust washes away cloth bag, reduces the load of cloth bag, extends cloth bag service life.
Detailed description of the invention
Fig. 1 is the operation principle schematic diagram for settling dirt pocket；
Fig. 2 is the structural schematic diagram that the utility model embodiment one settles bag-type combined dust collector；
Fig. 3 is the structural schematic diagram for the air guide member that the utility model embodiment one settles bag-type combined dust collector.
Specific embodiment
The embodiments of the present invention is described in further detail with reference to the accompanying drawing.
Embodiment one, referring to figs. 1 to Fig. 3, sedimentation bag-type combined dust collector provided in this embodiment includes shell, shell
Periphery is equipped with several support legs 4, is disposed with air-purifying chamber 3, dirt pocket 2 and ash bucket 1,2 He of dirt pocket from top to bottom in shell
It interconnects between ash bucket 1, is interconnected between air-purifying chamber 3 and dirt pocket 2 by card, air holes, dedusting are provided on card
Interior is provided with the filter bag equal with card air holes quantity, and the open end of filter bag is sealed in the air holes of card, sets on air-purifying chamber 3
It is equipped with air outlet 30, dirt pocket 2 is equipped with air inlet 20, is provided with sedimentation dedusting device at the air inlet 20 of dirt pocket, described
Sedimentation dedusting device includes settling baffle 5, support rod 6 and air guide member 7.The inside of air inlet 20 is fixed with perpendicular by support rod 6
To settling baffle 5, the outside of air inlet 20 is provided with air guide member 7.Air guide member 7 is an infundibulate cylinder, air inlet
Area is less than the area of gas outlet.
Preferably, air guide member 7 is by rounded transitional to rectangular infundibulate cylinder, and the circular open of air guide member is air inlet
End, square aperture are outlet side, and the square aperture area of air guide member is greater than the area of its circular open, the square aperture of air guide member
It is arranged at air inlet 20.Air guide member is designed as to one end circle one end is rectangular, square aperture can be with original rectangular air inlet
Mouth matches, rugged construction, good appearance.
Air inlet split-wind plate 720 is equipped at the gas outlet of air guide member, air inlet split-wind plate 720 is equipped with several ventilation holes,
Ventilation hole keeps air flow method uniform.
The working principle of the present embodiment is: positioned at the side of filter bag, there are sedimentation dedusting spaces 21 in dirt pocket 2, in dedusting
The air inlet of room housing is externally provided with air guide member 7, and dust laden air is entered by the lesser circular open 71 of air guide member 7, reaches air guide member
Biggish square aperture 72 when, due to volume enlargement, filtering velocity is reduced, and under the action of porous air inlet split-wind plate 720, is made
Air-flow is uniformly distributed, and into after crossing sedimentation dedusting space 21, is bumped against on settling baffle 5, cannot companion since dust inertia is larger
Gas changes direction together, loses the kinetic energy for continuing to fly upward, bulky grain ash fall is into following ash bucket 1.Containing little particle ash
The air of dirt comes together in air outlet 30 by air-purifying chamber 3 and is discharged after filter bag purifies, and dust is blocked in chimney filter outer wall, and attached
On filter cloth.
The beneficial effect of the present embodiment is: gravity settling chamber and bag filter are formed all-in-one machine by the utility model,
Positioned at the side of filter bag, there are sedimentation dedusting spaces in dirt pocket, first sink to large dust particle in sedimentation dedusting space
Drop reduces dust and washes away to cloth bag, reduces the load of cloth bag, extends cloth bag service life, and the utility model settles cloth bag group
It is reasonable in design to close deduster, reduces space occupied, is able to extend the service life of cloth bag.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
