Description
Technical field
The invention belongs to atmospheric sedimentation technical fields, are related to a kind of atmospheric heavy metal deposition acquisition device.
Background technique
Atmospheric sedimentation is followed in the Atmospheric particulates of earth's surface in global substance by gravity or souring natural subsidence
Play important role in ring.Atmospheric sedimentation is divided into dry deposition and wet deposition, dry depositing dust form include nature dust and
Dust storm, wet depositing dust are then the dust that the forms such as rainfall, snow hail are washed down from atmosphere.With industry, the swift and violent hair of communications
Exhibition, atmosphere heavy metal content caused by mankind's activity dramatically increases, and heavy metal element can then be transmitted by atmospheric medium into
Enter in another transfer, is a part very important in ecosystem circulation.
Some researches show that atmospheric sedimentation is the important channel that trace heavy metal element transmits in the environment, is raw in environment
The primary outer source of object available heavy metal.Influence of the atmospheric sedimentation trace heavy metal element enrichment to environment is particularly sensitive,
With long-term potential hazard.For example, atmosphere heavy metal can pass through combustion of fossil fuel, vehicle exhaust, flue gas and dust storm etc.
It into atmosphere, and is adsorbed on aerosol, soil or water body is then entered by atmospheric sedimentation, cause the dirt of soil and water body
Dye；Atmospheric heavy metal deposition also will affect the growth of crops simultaneously, also will affect the quality safety of agricultural product；It even can be direct
Be not intended to suck by people, breathe, the approach such as skin contact enter human body, be detrimental to health.Therefore, atmospheric heavy metal deposition has been
The extensive concern of people is caused, foreign countries start from the research of heavy metal element in precipitation, depositing dust in the 1970s, at present
The country also expands more research, all achieves different degrees of effect.
The research most widely used method of atmosphere dried wet deposition heavy metal pollution is to be proposed earliest by R ü hling and Tyler
, it be the biological monitoring technology (R ü hling et al., 1968) for monitoring substance that they, which advocate with moss, that is, utilizes bryophyte
The particulate matters such as heavy metal in atmosphere are adsorbed onto plant by " particle capture " and " ion exchange resin exchange " two ways
Surface achievees the effect that absorption, enrichment pollutant, therefore can be using the blade of this kind of plant as collector.Additionally
There are some active sampling methods (Pereira et al., 2007) based on various traffic sampling devices, utilizes the acquisition of each quasi-instrument
The particulate matters such as the heavy metal in atmosphere.
Moss method is most widely used method, but due to environmental condition difference, various regions moss kind is inconsistent, and portion
The normal growth of seriously polluted region moss is divided to be suppressed, institute is in this way on a large scale with upper it is possible that analysis
As a result the problems such as valid data can not being obtained without comparativity or even part monitoring point.Active sample mode has sampling
Advantage convenient, the period is shorter, while also can relatively accurately reflect the moment concentration water of Heavy Metals In Atmospheric Particles element
It is flat, but cannot effectively reflect the natural subsidence process of atmosphere dried wet deposition, Flux generally requires thick by model
It slightly estimates, and instrument cost is high.Existing passive type sampling, sampling apparatus is too simple, and sample collection cylinder height is lower, no
The problem of being avoided that reentrainment of dust.
Summary of the invention
Present invention solves the problem in that a kind of atmospheric heavy metal deposition acquisition device is provided, it can be more objective and accurate
Ground is reflected in the settling amount of Heavy Metals In Atmospheric Particles element under the conditions of true nature, and it is heavy currently for atmosphere heavy metal to solve
Drop collects inaccuracy, collects the problem of big environmental difference, " reentrainment of dust ".
The present invention is to be achieved through the following technical solutions:
A kind of atmospheric heavy metal deposition acquisition device including the collecting vessel being arranged in fixing pipe and accepts bucket, collecting vessel
Positioned at the lower section for accepting bucket, the upper opening for accepting bucket is exposed outside fixing pipe, and the lower opening for accepting bucket is equipped with funnel, and funnel goes out
Mouth is connected by conduit with the opening of collecting vessel.
The fixing pipe is connected and composed by upper fixing pipe and lower fixing pipe by connecting tube, is accepted bucket and is arranged in upper fixation
In pipe, upper opening exposes upper fixing pipe, and collecting vessel is arranged in lower fixing pipe.
The length of upper fixing pipe is greater than the length of lower fixing pipe.
The under shed of the undertaking bucket is directly gradually restrained, and the opening to match with funnel is formed.
Mesh enclosure is additionally provided at the funnel openings.
The opening of the collecting vessel is fixedly connected with conduit.
Anti-pollution cover, the dichotomy being extended on anti-pollution cover are additionally provided at the undertaking bucket upper opening.
The fixation bottom of the tube is additionally provided with bracket, and bracket includes accepting the supporting leg of pallet and setting thereunder.
Compared with prior art, the invention has the following beneficial technical effects:
Atmospheric heavy metal deposition acquisition device provided by the utility model, than moss method closer to the true drop of nature
Dust quantity can preferably reflect the process of heavy metal element natural subsidence, reduce the difference with natural environment, and compare and be based on instrument
The acquisition method of device reduces the error of calculating, has saved cost, and the experimental data obtained is made to have more accuracy and convincingness.
And upper plastic bucket has deepened height, and the depth of 50cm avoids reentrainment of dust to a certain extent, prevents rainfall from leading to depositing dust
Secondary loss.
Atmospheric heavy metal deposition acquisition device provided by the utility model, the present apparatus are whole all using materials such as PVC, plastics
Matter ensure that sedimentation sample is not influenced by other metallic elements.Outside uses PVC material, and chemical stability is good, anti-corrosion is resistance to
Aging, the secondary pollution that water can be prevented and less scaling, moreover it is possible to reduce direct sunlight, reduce evaporation, plastic net cover can block compared with
Big substance avoids blocking funnel, ensure that the unobstructed of sedimentation sample collection.The integrated energy of cylindric stainless steel A-frame
The stability of enhancement device facilitates experiment to acquire with putting with adopting.
Atmospheric heavy metal deposition acquisition device provided by the utility model more has practical value in actual operation,
The dendritic stainless steel coil at top can not only reduce extraneous interference when sample acquires, but also will not influence rainwater
Component successfully avoids the accuracy for influencing data.It is not necessarily to power supply in field, operation is simple, and a people is only needed to can be completed from putting
Set all operations of acquisition.Experimentation cost is reduced, test period is saved.
