Description
Technical field
The present invention relates to a kind of atmospheric sedimentation harvesters of multi-mode.
Background technology
Currently, the device being acquired to POPs in air (persistence organic pollutant) is less, and dried wet deposition is adopted
Collection technology is usually by dry deposition and mixing sedimentation separately sampling, it usually needs according to weather condition, respectively to dry deposition or dry
Wet mixing is closed sedimentation and is acquired, and needs to put into more human resources, when carrying out time and the prodigious acquisition of spatial extent range,
It is then limited by larger, also has patent document that dry deposition and mixing are settled both samplings and be integrated in one, but need using biography
Sensor differentiates weather conditions, and structure is complex, and failure rate is higher and it is necessary to match stand-by power source, can not be adopted for a long time
Collect operation.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of atmospheric sedimentation harvester of multi-mode, can carry out
The long-term unmanned sampling in field, and acquisition is separately adjusted without special messenger to the POPs dry depositions of air and mixing sedimentation.
In order to achieve the above object, the technical solution adopted by the present invention is that：
A kind of atmospheric sedimentation harvester of multi-mode, including holder, pedestal upper end are fixed with bottom shell, bottom shell
On be provided with the grid of foamed material, telescopic supporting rod is also vertically installed in bottom shell, telescopic supporting rod upper end is solid
Determine top shell, mixing sedimentation sampler is set in top shell.
Further, the bottom shell is stainless steel, bottomless peviform shape, on diametrically 27.5cm,
Bottom opening diameter 17.5cm.
Further, the foamed material is the polyurethane foam for adsorbing air POPs dry depositions, and diameter 10cm is high
0.7cm。
Further, the grid is stainless steel, entire outer diameter 33.5cm.
Further, the top shell is stainless steel, is inverted peviform shape, under diametrically 40cm, high 13cm, shell
Top is equipped with the groove for placing mixing sedimentation sampler.
Further, the groove is cylindrical shape, diameter 11.5cm, high 14.5cm.
Further, the mixing sedimentation sampler includes the burette that specification is 1000ml, in the cup of burette
Pars intramuralis uniformly smears a floor height Molecularly Imprinted Polymer ethylene-vinyl acetate resin.
Further, the telescopic supporting rod is retractable to longest duration 60cm, most in short-term 30cm.
Beneficial effects of the present invention：
The present invention can place the top shell of mixing sedimentation sampler by setting, on the one hand can carry out air dry and wet
Mixing sedimentation acquisition, on the other hand when there is the weather such as sleet, avoids sleet from accomplishing the influence of the dry deposition sample acquired
Two kinds of acquisition modes are integrated but are independent of each other；
Using measuring cup in conjunction with the strong adsorpting polymerization object in measuring cup, the POPs objects in rainfall and depositing dust can be effectively adsorbed
Matter, while hot weather POPs volatilization losses；Absorption using polyurethane foam as dry deposition can be good at adsorbing air
The POPs of middle gaseous state and particulate form.
In addition, the device of the invention is not necessarily to power supply, cheap, small volume is easy to operate；It can be in large-scale dimension model
Enclose it is interior arrangement and continuous monitoring are synchronized to multiple sampled points, be suitble to sampling point distributions it is wide, acquisition time length air
POPs settlement monitorings.

Specific implementation mode
The present invention will be further described with reference to the accompanying drawings and examples.
Embodiment
As shown in Figures 1 to 3, the atmospheric sedimentation harvester of a kind of multi-mode, including holder 1,1 upper end of holder are fixed with bottom
Portion's shell 2, the bottom shell 2 are stainless steel, bottomless peviform shape, on diametrically 27.5cm, bottom opening diameter
17.5cm；The grid 3 of foamed material 4 is provided in bottom shell 2, which is stainless steel metal material, durable,
Entire outer diameter 33.5cm, plays ventilative effect in the form of grid, and the foamed material 4 is absorption air POPs dry depositions
Polyurethane foam, diameter 10cm, high 0.7cm；Telescopic supporting rod 5 is also vertically installed in bottom shell 2, the retractable support
Bar 5 is retractable to longest duration 60cm, most in short-term 30cm, can arbitrarily adjust height according to actual needs, and 5 upper end of telescopic supporting rod is solid
Determine top shell 6, the top shell 6 is stainless steel, is inverted peviform shape, under diametrically 40cm, high 13cm, the design
On the one hand can carry out air dry and wet mixing sedimentation acquisition, on the other hand can when there is the weather such as sleet, can prevent sleet into
Enter bottom dry deposition collection container, the influence for avoiding it from acquiring dry deposition；It is equipped at the top of shell and places mixing sedimentation sampler 7
Groove 8, groove 8 are cylindrical shape, diameter 11.5cm, high 14.5cm, setting mixing sedimentation sampler 7, the mixing in groove 8
The burette that 7 specification of sampler is 1000ml is settled, cup wall interior uniformly smears a floor height Molecularly Imprinted Polymer ethyl vinyl acetate second
