Description
Technical field
The present invention relates to the adsorbent equipment of a kind of air small particles, belong to air purification field.
Background technology
In recent years, the particulate pollutant in air is increasing.The granules such as the PM2.5 in such as air, PM10 are seriously endangered
Do harm to the health of people.Traditional air purifier cannot small particles of pollution thing in air-isolation.So, electrostatic (ionizes)
Purification techniques arises at the historic moment.But, the shortcoming of electrostatic (ionization) purification techniques is also apparent from.Such as, 1. it is high to air release
Piezoelectricity can produce ozone irritant to pulmonary.The particulate matter not the most being caught in can become bigger charged of human injury
Particulate matter is also discharged into indoor.3. the particulate matter being captured can come back in air.4., along with use, purification efficiency drops
Low.5. need often to safeguard.
Accordingly, it would be desirable to the depurator that design is harmless to human health.Thermophoretic effect refers to that little granule or particulate exist
When there is motion in the fluid of thermograde, owing to when cold and hot differentiation collides from it, the momentum of transmission is different, and on the whole
Show as the effect by the power in opposite direction with thermograde (sensing hot-zone, cold-zone), make little granule produce and thermograde phase
Anti-movement velocity, and the process being deposited on low-temperature surface.
Summary of the invention
It is an object of the invention to for existing air cleaner deficiency during adsorption particle, it is provided that Yi Zhongxin
Air particles adsorbent equipment.The sorption channel of this adsorbent equipment is through Fluid Mechanics Computation particular design, then is aided with and adds hot charging
Put to realize short grained seizure, thus improve the adsorption efficiency of device.
In order to realize foregoing invention purpose, the technical solution used in the present invention is:
The present invention is by air intake region, adsorbent equipment region and blower fan region three part composition, the wherein air intake region of Part I
Using the inlet design that circular arc is tapering type, it uses level design with adsorbent equipment coupling part；Adsorbent equipment employing level sets
Meter, upper wall surface connects heater, and lower wall surface is laid activated-carbon device and tentatively adsorbed.Upper lower wall surface all uses two kinds of sawtooth
Design.The sawtooth of runner first half is cone, and tooth pitch is narrower, the closeest；The sawtooth of latter half is cone, tooth pitch
Wider, the thinnest.One section of air-flow meadow is left in last blower fan region, has one piece of total cross-section filter septum afterwards in centre
(with cavity cross-section consistent size and dismantled and assembled) carries out secondary filter, and dividing plate non-ventilating bore portion scribbles the stickums such as glycerol,
Exhaust blower uses low power blower fan to ensure slow transitting through of granule air-flow.
The present invention compared with prior art, has the beneficial effect that
1, existing air cleaner, the more design using vertical runner of the most family air purifier.This
The runner design of bright employing level, can be prevented effectively from produced adsorption plane problem of non-uniform during air vertical upflow.
2 compared with relatively advanced electrostatic (ionization) formula air purifier, and the present invention has following improvement: 1. break through formula
Use heater, utilize the thermophoretic effect to make its natural sediment, it is to avoid the ozone discharged in the ionization process thorn to human body
Swash；2. the zigzag design employed in flow passage structure can increase granule deposition effectively, thus is prevented effectively from large
The particulate matter grasped comes back to be detrimental to health in air；3. on adsorption zone, lower wall surface is removable, and can enter
Row regularly cleans, and such design can effectively delay the time that purification efficiency reduces.
3, the present invention uses low power blower fan as mobilization dynamic device.Its objective is to ensure that granule air-flow slowly leads to
Cross, increase the deposition of granule as far as possible.And it has the advantage that noise is little.

In figure: 1, gas feed, 2, conicle sawtooth, 3, big circular cone sawtooth, 4, heater, 5, lower wall surface is (containing active
Charcoal), 6, small-power exhaust blower, 7, filter septum, 8, passage, 9, activated carbon.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-3, air enters from gas feed 1, enters adsorbent equipment district after entry zone.Air is being inhaled
Adsorption device region first has to the purification filtering through conicle sawtooth 2, and this broached-tooth design tooth depth is less, and space width is closeer, purpose
It is to reduce the impact on flowing of this structure.After first purifies, gas enters the purification of big circular cone sawtooth 3.It is worth
It is to be noted that broached-tooth design design connects heater 4 due to upper wall surface, lower wall surface 5 places activated carbon 9, thermophoretic effect and activity
The chemical property of charcoal can produce preferable little particle filtering effect.Last air enters blower fan region, has filtration in the middle of this region
Dividing plate 7, dividing plate is coated with in addition to passage 8 stickum such as glycerol can effectively be sticked the particulate matter of residual at screen plate
On, thus secondary increases purification efficiency.Finally, gas is by outside small-power exhaust blower 6 discharger.
Furtherly, with air inlet height D as reference, device entirety width 3D, based on square structure；Air inlet is to inhaling
Adsorption device entrance horizontal range is 0.5D；Adsorbent equipment region total length 0.75D, the overall high 0.3D of passage, top and bottom broached-tooth design
Summit is away from respective wall 0.05D, and the first broached-tooth design tooth depth 0.0125D, sawtooth width 0.025D, angle is 45 °, and space width is
0, this toothed segment total length 0.25D, the second broached-tooth design tooth depth 0.00625D, sawtooth width 0.0125D, angle is 45 °, space width
For 0.0125D, this toothed segment total length 0.5D；Last blower fan region total length 0.35D, has the filtration of a block length 0.005D in centre
Dividing plate.Filter septum is mounted with the air vent of 330 diameter 0.0625D the most respectively altogether with 0.0125D for spacing.
The present invention is based on thermophoresis phenomenon, and compared to electrostatic (ionization) purification techniques, this technology is more easy to realize and avoid electricity
Harm from radiation.As shown in Figure of description 4,5, along with the increase of the cold and hot temperature difference in region, sinking of different-grain diameter small particle
Long-pending rate and deposition velocity have and improve significantly.In conjunction with the research in terms of thermophoresis, it is known that the design realizes the bar of the big temperature difference at device
The deposition of small particle can be greatly improved under part.
To sum up, adsorbent equipment is designed by the present invention, makes purification process simpler, more efficiently and without new harm
The side-product of health produces.
The above, be only presently preferred embodiments of the present invention, not impose any restrictions the present invention, every according to the present invention
Any simple modification, change and the equivalent structure change that above example is made by technical spirit, all still falls within skill of the present invention
In the protection domain of art scheme.
