Technical field
The utility model relates to the dust suppression of a kind of band conveyor falling point compound type, dust collector.
Background technology
At present, large specification and the remote band conveyor of carrying often have a plurality of transhipment websites in transportation, and, between prime and rear class belt transporter, there is certain drop.When material is discharged into lower from eminence, always produce certain airborne dust near belt feeder, along with the diff-H increase of falling point, dust emission increases.The reason that produces airborne dust mainly contains following several respects:
1, material is in transportation, and the inertia producing when departing from belt, makes dust depart from material, and generation is flown upward
2, the belt of conveyer and the running of mechanical device, the air-flow carrying, causes flying upward of dust in material.
When 3, material is discharged into lower from eminence, material has certain potential energy, and after unloading and putting, potential energy is converted into kinetic energy, makes dust produce Impact Sputtering, and departing from material surface becomes airborne dust.
In these factors, the Dust Capacity of the third generation is maximum.
In order to suppress and reduce the airborne dust of band conveyor falling point, people studied a lot of measures and scheme.At belt transport place atomized water spray the earliest and the most simply.This way, has certain effect to dust suppression (depositing dust), and still, effect is not ideal, and main is that grasp greatly by few being difficult for for water smoke.Spray little, out of reach effect, sprays large, and after material humidification, viscosity increases, and brings the counter productives such as belt wearing and tearing and equipment corrosion.
In recent years, generally adopt dry dust collection device, at airborne dust point place design enclosed hood and check apron, prevent that in enclosed hood, dust is raised outward.Dedusting unit is directly installed on belt feeder enclosed hood, and the blower fan by dedusting unit makes to produce negative pressure in enclosed hood, extracts the dusty gas in enclosed hood, and the dust of collecting is removed again and returned on belt feeder.Dry method dust arrester installation has more advantage than the device for reducing dust of wet type, but also has some problems.At high drop place, the speed of blanking place dust sputter is larger, after the negative pressure of dust arrester installation will acquire a certain degree, could produce at airborne dust place larger negative pressure, thereby plays the effect of dust suppression.But when negative pressure is larger, the dust of not kicking up on belt feeder is also inhaled in dedusting unit, causes dust concentration large, filter bag ash removal is latch up phenomenon even frequently.Meanwhile, the invalid gas sucking from partial enclosure is also many.Also have, when material particles is when large (as coal cinder), from eminence, be directly discharged into the belt feeder of below, below produce on belt and aggravate its wearing and tearing compared with large impact.

But, the dust collector of this version, the part that still comes with some shortcomings, mainly contains following several respects:
1, up with on the enclosed hood of below belt feeder dedusting unit is set respectively, just not saying the height of cost of manufacture singly just install, operation control and management aspect, just cumbersome.
2, below belt feeder is installed away from dirt source point, and the length of enclosed hood is larger, although place, dirt source has taked return flow line, the dust sputtering rate at blanking place is still higher.
3, the deashing of unit adopts the form of chamber spray, that is to say, utilizes pressurized air to all filter bags while deashings in unit.During deashing, the pressurized air spraying into, pressure is greater than the negative pressure value of unit, and speed is also higher, produces instantaneous malleation in unit and in enclosed hood, can aggravate flying upward of dust.In the time of deashing, filter bag also can instantaneously lose filtering function, is unfavorable for the long-term and stable of system operation.
4, dust is discharged into lower from eminence, and the potential energy that the drop of material produces can not be eliminated, and drops on the kinetic energy producing on material feeding belt feeder, makes dust produce the possibility of flying upward and always exists.
