Description
Technical field
The present invention relates to a kind of PM2.5 abatement equipments, more particularly to a kind of PM2.5 open airs abatement equipment.The present invention is also
It is related to the application of the PM2.5 open airs abatement equipment.
Background technology
PM2.5 refers to particulate matter of the aerodynamic diameter less than or equal to 2.5 μm in air.Its main source is combustion
Coal, vehicular emission, building dirt, airborne dust, biomass combustion, secondary sulfate and nitrate and Organic substance.Wherein coal-fired dirt, raise
Dirt, Organic substance and secondary sulfate and nitrate contribution rate are larger.
PM2.5 can long-term suspension in atmospheric environment, with very big specific surface area, it is easy to be enriched with polycyclic aromatic hydrocarbon, multi-ring
The noxious substances such as benzene class, virus and antibacterial, and Trace poisonous elements；PM2.5 is also called lung particulate matter, can enter people
Body alveolar even blood circulation, once deposit in human respiratory will produce serious harm.PM2.5 is to cause simultaneously
The key factor of the great environmental problems such as atmospheric visibility reduction, haze weather and Global climate change.
Because PM2.5 is distributed widely in the middle of the air of life, currently without the PM2.5 that good method is administered in air,
The present invention provides a kind of purification technique that can be used out of doors, for the haze pollution administered in living environment.
The content of the invention
First technical problem to be solved by this invention is to provide one kind, and effectively to administer PM2.5 for outdoor environment dirty
Dye, the PM2.5 open airs abatement equipment killed antibacterial, improve air quality.
Second technical problem to be solved by this invention is to provide the application of the PM2.5 open airs abatement equipment.
In order to solve first technical problem, the PM2.5 open airs abatement equipment that the present invention is provided, in closed airduct, middle part sets
There is axial flow blower, high pressure atomizing nozzle, high pressure mist are provided with before the air intake of axial flow blower in the air intake of closed airduct
Change nozzle is made mist machine with high pressure and is connected, and the outlet air end in axial flow blower in closed airduct is provided with negative oxygen ion generator, close
The inwall for closing the outlet air end of airduct is provided with conductive layer.
In order to solve second technical problem, the application of the PM2.5 open airs abatement equipment that the present invention is provided, along improvement place
Surrounding arrangement PM2.5 open airs abatement equipment, the air containing PM2.5 are pumped in closed conduct by axial flow blower, first pass around mist
Change area, increased the humidity of dust, then through axial flow blower, in blower fan air-out direction, be disposed with negative oxygen ion generator, bear oxygen
The negative oxygen ion sent by ion generator makes dust that solidifying change to occur, and increases the high dust of dust granules, especially water content, more
Easily condensed, the dust granules after cohesion, diameter increase is easily settled；In the air-out direction of axial flow blower, closed airduct
Conductive layer is set, and powered dust can be directly adsorbed on the conductive layer, effectively administer sucked dust in air so as to play
Effect.
Using PM2.5 open air abatement equipments and its application of above-mentioned technical proposal, high pressure mist is arranged in closed airduct one end
Change nozzle, its atomizing particle size constitutes sections of atomization between 10nm-10 μm；After sections of atomization, disposed axle stream inside closed airduct
Blower fan, its air quantity administer area design according to actual, and the inlet scoop of axial flow blower is against sections of atomization；In the air-out side of axial flow blower
To, negative oxygen ion generating device is arranged, its power administers area and pipe diameter design according to actual；In negative oxygen ion generator
Leading portion, leaves enough duct lengths, makes dust settling use conducting metal inside this section of region, the closed airduct in the region
Material makes conductive layer.Air containing PM2.5 is pumped in closed conduct by axial flow blower, first passes around range of atomization, be increased
The humidity of dust, then through axial flow blower, in blower fan air-out direction, it is disposed with negative oxygen ion generator, negative oxygen ion generator
The negative oxygen ion for being sent makes dust that solidifying change to occur, and increases the high dust of dust granules, especially water content, it is easier to coagulated
Poly-, the dust granules after cohesion, diameter increase are easily settled；Arrange conductive in the air-out direction of axial flow blower, closed airduct
Layer, powered dust can be directly adsorbed on the conductive layer, so as to play a part of effectively to administer sucked dust in air.
The present invention has the advantages that：
It is in the case where dust humidity is increased, charged to dust, the cohesion of dust is increased, PM2.5 dust is made more
Easily cohesion becomes bulky grain.Because being arranged in pipeline, the adsorbing powder dust in air can be made in pipeline, so as to through pipeline
The air for occurring afterwards is fresh air.Dust settling in pipeline, easily clear up by periodic cleaning pipeline.
The present invention is applied in outdoor zones such as park, school, residential block, hospital, shopping centres, can effectively administer city
PM2.5 pollutes, and kills antibacterial, improves urban air-quality.
In sum, the present invention is that one kind can effectively administer PM2.5 pollutions, kill antibacterial, improves empty for outdoor environment
The PM2.5 open air abatement equipments of makings amount and its application.
