Description
Technical field
The utility model relates to a kind of gas sampler, particularly relates to a kind of gas automatic sampling device.
Background technology
Environmental issue is an extremely global social concern of attracting attention at present, on the awareness and understanding air pollution of air pollution source on the impact of environment, most important to people, gas sampler is for gathering tested air sample and passing through filter paper test, draw the kind of each pollutant in tested air and the concentration of tested sample pollutants in air, existing gas sampler is all heavier, take up room large, not easily place, and all need staff to use samplers sample air sample, waste of manpower, existing gas collector does not all arrange filtration treatment device, can not process residue sample.
Utility model content
The purpose of this utility model is just to provide a kind of gas automatic sampling device to solve the problem.
In order to achieve the above object, the utility model have employed following technical scheme:
A kind of gas automatic sampling device, comprise protecgulum and base, described a kind of gas automatic sampling device also comprises active carbon layer and sucker, described base and described protecgulum are threaded connection, O-ring seal, filter membrane, gauze, pressure ring, filter paper and supporting plate is provided with successively between described protecgulum and described base, described protecgulum is provided with multiple air admission hole uniformly, described supporting plate is provided with multiple through hole uniformly, described active carbon layer is arranged in described base, described sucker is arranged on the bottom surface central authorities of described base, and the sidewall of described protecgulum is provided with link.
In said structure, O-ring seal, filter membrane, gauze, pressure ring, filter paper and supporting plate are all arranged between protecgulum and base, protecgulum and bottom are threaded connection, and make the utility model volume little, link or sucker, make the utility model can adapt to the placement in all kinds of place, the relatively existing gas sampler that takes up room is little, and the air admission hole on protecgulum enters the collection that air completes air sample, does not need staff to gather, saved manpower, active carbon layer can process residue sample.
Particularly, the bottom surface of described base is provided with multiple venthole uniformly; Described filter membrane is nuclear pore filter film; Described gauze is 70 object terylene gauzes.
The beneficial effects of the utility model are:
O-ring seal of the present utility model, filter membrane, gauze, pressure ring, filter paper and supporting plate are all arranged between protecgulum and base, protecgulum and bottom are threaded connection, therefore the utility model volume is little, and link or sucker, make the utility model can adapt to the placement in all kinds of place, the relatively existing gas sampler that takes up room is little, the utility model gathers air sample automatically by the air admission hole on protecgulum, staff is not needed to gather, save manpower, the utility model is provided with active carbon layer, can process residue sample.

In figure: 1-air admission hole, 2-link, 3-protecgulum, 4-O-ring seal, 5-filter membrane, 6-gauze, 7-pressure ring, 8-filter paper, 9-supporting plate, 10-active carbon layer, 11-base, 12-venthole, 13-sucker.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Figure 2 and Figure 3, a kind of gas automatic sampling device of the utility model, comprise protecgulum 3 and base 11, a kind of gas automatic sampling device also comprises active carbon layer 10 and sucker 13, base 11 and protecgulum 3 are threaded connection, O-ring seal 4, filter membrane 5, gauze 6, pressure ring 7, filter paper 8 and supporting plate 9 is provided with successively between protecgulum 3 and base 11, protecgulum 3 is provided with uniformly multiple air admission hole 1, supporting plate 9 is provided with multiple through hole uniformly, active carbon layer 10 is arranged in base 11, and sucker 13 is arranged on the bottom surface central authorities of base 11; The sidewall of protecgulum 3 is provided with link 2; The bottom surface of base 11 is provided with uniformly multiple venthole 12; Filter membrane 5 is nuclear pore filter film; Gauze 6 is 70 object terylene gauzes.
Principle of the present utility model is as follows:
Air enters this collector by the air admission hole 1 on protecgulum 3, writes down the time of gas diffusion, passes through computing formula: W=(D × A/L) × (C-CO) × t × 10
-3
In formula: W---the content (μ g) of the tested pollutant that absorbed layer collects;
The molecule of D---tested pollutant is at the coefficient of diffusion cm of air
2/ min;
A---total effective diffusion area cm
2;
L---total effective diffusingsurface length cm;
C---the concentration mg/m3 of tested pollutant in surrounding air;
C0---at its surface, the concentration mg/m of tested pollutant
3;
T---open-assembly time, i.e. sampling time min.
C0=0 can be thought at this, and make: K=D × A/L is a constant.
Above formula is written as: C=W/ (Kt × 10
-3)
Known K, records W and t, can calculate the concentration of tested pollutant in surrounding air.
