Description

A kind of external wall brick based on blade biomimetic features, its application and lay the dust and subtract haze Method
Technical field
The present invention relates to a kind of external wall brick based on blade biomimetic features, its application and lay the dust and subtract haze method, belong to Science of residential environment, urban forestry scientific domain.
Background technology
Haze is the general statement to various suspended particulate substance content overproofs in air, the ash being embodied in air The aerosol systems of the particulate matters such as dirt, sulfuric acid, nitric acid, organic hydrocarbon compounds composition cause dysopia.Wherein, in air Sulfur dioxide, nitrogen oxides and pellet this three is the main composition of haze, and the above two are gaseous contaminant, and Particulate matter is then the arch-criminal for aggravating haze weather pollution.They are combined together with fog, allow sky moment to become grey illiteracy Cover, form haze pollution air.The english abbreviation of particulate matter is PM, especially PM2.5(Equivalent aerodynamic diameter is less than Particulate matter equal to 2.5 microns)It is considered as " arch-criminal " for causing haze weather.
Haze weather increases, and the health hazard to people is very big.Especially diameter is below 0.0025-0.01 microns Floating particle thing, i.e. PM2.5-PM10, bronchus, or even lung directly can be entered by respiratory system.PM2.5-PM10 etc. Grain thing in addition to being loaded with the higher pollutant of sulfur dioxide, nitrogen oxides equal size, it is also possible to include acid, alkali, salt, amine, Phenol, or even influenza virus, tubercle bacillus, pneumococcus etc..Therefore, haze is very harmful to the health of people.Long-term life In haze weather, it is very easy to that the diseases such as breathing problem, cranial vascular disease, nasal cavity inflammation occur.In November, 2013, the world Health organization announces that air pollutants are " one of most dangerous environmental carcinogenesis materials " on the earth.Meanwhile haze weather can also carry The risk of high transmission.
In recent years, the haze weather in China is increasingly severe.The formation of haze is existing " source ", also there is " accomplice ", and it is led It is graininess airborne dust particulate to want source, such as China possesses Loess Plateau maximum in the world, and its soil texture is most easily raw Into graininess airborne dust particulate.There are the gaseous contaminants such as graininess airborne dust particulate, industry, vehicle exhaust just to have carrier.Secondly, people The differences in motion come for active belt is very easy to cause airborne dust.For example, the soil of flower nursery and street is rainy or bold and vigorous among road If thering is mud to flow on road after water, after one hour dry, quickly run over by wheel and will result in a large amount of airborne dusts, even if these particles Property material drops back into ground, also can constantly be crossed because of automobile, is thrown to city overhead again.In addition, and in the range of certain space When humidity is higher, graininess airborne dust particulate and motion process are collected in this spatial dimension, and particulate matter will be combined with fog Form haze.While China's rapid development in recent years, increasing for haze is also brought.For example, the construction in all kinds of chemical plant, The exploitation of all kinds of mineral products such as stone material and coal, the increase of automobile etc., not only increase carrier --- the graininess airborne dust of haze Particulate, it also add gaseous contaminant.
How haze is prevented and treated, be the important topic that we urgently study.From the point of view of the principle and reason that haze is formed, preventing and treating The approach of haze mainly includes:Prevent airborne dust, emission reduction gaseous contaminant and subtract haze.Wherein, airborne dust and emission reduction gaseous contamination are prevented Thing is from source, such as is stopped production by cement winter and can reduce carrier --- the graininess airborne dust particulate of haze;Pass through Close the discharge of the less gaseous contaminant in chemical plant.In recent years, substantial amounts of work has been done in terms of the preventing and treating in haze source by China, Achieve certain effect.In terms of haze is subtracted, related scholar have also been made some researchs, such as pass through release electrostatic particle in the air Haze particle etc. is captured, but also never has very effective implementation.
Ornamental plant is considered as the optimal selection for purifying air always, and the especially blade of ornamental trees and shrubs can be effective Lay the dust and subtract haze.However, in dwelling environment construction, substantial amounts of building instead of original phytobiocoenose.As can be seen here, building is allowed to have The function that lays the dust of having plant leaf blade will be that effective lays the dust subtracts haze approach.If each building is all one big tree, that Its exterior wall tile can be considered as " blade " set greatly.Therefore, allow external wall brick surface biomimetic plant leaf blade surface it is micro- Structure is seen, so as to the function that lays the dust with plant leaf blade, it is possible to realize that laying the dust for building subtracts haze.
At present, the exterior wall tile that construction industry uses mainly has two kinds, and a kind of is currently with more environmentally friendly exterior wall tile, surface Imitative porcelain and it is smooth, there is no electrostatic, not dust suction.Although this exterior wall tile overcomes urban architecture dust and had one's face covered with is difficult to clearly The drawbacks of washing, but subtract haze then without any effect to laying the dust.Another kind is traditional fired brick, and its surface has different degrees of Depressions or protrusions.This exterior wall tile has preferable suction-operated to particulate matters such as PM2.5, PM10 in air, but rainwater But the dust of absorption can not be eluted completely completely, then, these dust will continue to fly into air under wind action, The effective function that lays the dust can not be played.
The content of the invention
The invention provides a kind of external wall brick based on blade biomimetic features, its application and lay the dust and subtract haze method, can Laid the dust with to be efficiently used for realization and subtract haze.
The technical scheme is that:A kind of external wall brick based on blade biomimetic features, including brick body 3, the brick Body 3 is photo frame type structure, and photo frame type structure outer rim is provided with the flowing water mouth 1 communicated with draining arteries and veins 4, set at the interconnection of brick body 3 There is gutter channel 2, photo frame type structure concave interior arcuate surface devises some fine hair 5 that lay the dust, and draining arteries and veins 4 is depressed in arcuate surface It is interior, it is same level with flowing water mouth 1, gutter channel 2.
Brick body 3 is made of sintering brick.
Brick body 3 is variously-shaped.
Brick body 3 is shaped as rectangle, square or rhombus.
The fine hair 5 that lays the dust is the trichome similar to blade, is made up of polystyrene plastics or string.
External wall brick based on blade biomimetic features is used to lay the dust to subtract haze.
A kind of external wall brick of the use based on blade biomimetic features, which lay the dust, subtracts the method for haze, and the phase of brick body 3 is interconnected Practice midwifery raw gutter channel 2, the fine hair 5 that lays the dust is laid the dust by electrostatic adsorption absorption, the fine hair 5 that lays the dust is washed away by water, with dust Muddy water flow into draining arteries and veins 4 and converge muddy water to flowing water mouth 1, then muddy water is sent to ground by gutter channel 2, realization subtracts haze.
The beneficial effects of the invention are as follows:By the fine hair that lays the dust, dust is sufficiently adsorbed, while water is collaborated by draining kank Groove successfully elutes dust, delivers to earth's surface, can effectively alleviate haze, subtracts haze performance significant role to laying the dust.
