Furthermore, the heating device comprises a heater and a circulating pipeline, and the heater is mounted on the circulating pipeline. With the adoption of the aerosol collecting device, aerosol particulate matter samples can overcome the gravity settling effect to be in a flowing state so as to be suspended in the sample box, and the form of aerosol is kept.
Description
Technical field
The present invention relates to a kind of gasoloid gathering-device, belong to environment monitoring instrument field.
Background technology
The method that the collection of aerosol sample is conventional is by particulate collection on filter membrane, takes back laboratory and analyzes.Up to now, still do not have one particle can be collected in a vessel with aerocolloidal form, and take back the method for sampling analyzed in laboratory from strange land.
Gaseous sample can be captured in bag by a kind of gas sampling bag, take back laboratory to analyze, but it is inapplicable for aerosol sample, because have the haulage time of 2 ~ 3 hours could analyze to laboratory after the spot sampling of strange land, during this period of time, in gasoloid, aerosol sample can produce sedimentation because of Action of Gravity Field in sampler bag, is attached on sampler bag wall, can not meet laboratory and analyze requirement.
Summary of the invention
For the deficiency existing for prior art, the invention provides a kind of gasoloid gathering-device, aerosol particle matter sample can be made to overcome gravity settling effect, be in flow state, thus be suspended in sales kit (SK), to keep aerocolloidal form.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of gasoloid gathering-device, comprises sales kit (SK), airbag, heating arrangement, vacuum pump, pressure vacuum meter, draft tube and escape pipe; Described airbag is placed in sales kit (SK) inside, near upper surface; Described heating arrangement is placed in sales kit (SK) inner lower; Described draft tube is placed in sales kit (SK) side, between draft tube and sales kit (SK), be equipped with gas admittance valve, and described escape pipe is placed in sales kit (SK) opposite side, and it is connected with vacuum pump by the air outlet valve be arranged on escape pipe.Further, described heating arrangement comprises well heater and circulation duct, and well heater is arranged on circulation duct.
Further, described pressure vacuum meter is arranged on sales kit (SK).
Further, described airbag open side is equipped with valve F.
The invention has the beneficial effects as follows: the effect 1, utilizing atmospheric pressure, particle can be collected in a vessel with aerocolloidal form, take back laboratory with aerocolloidal form and analyze.2, utilize electrically heated mode to make air local heating in sales kit (SK), hot-air moves upward, and cold air moves downward, form circulation, make the aerosol sample in sales kit (SK) overcome gravity settling effect, be in flow state, thus be suspended in sales kit (SK), keep aerosol state.3, the airbag in sales kit (SK) can make the sample concentration extracted out in sales kit (SK) keep evenly.
4, equipment safety reliable, simple to operate, be easy to carry.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present invention.
1. sales kit (SK); 2. airbag; 3. heating arrangement; 4. vacuum pump; 5. pressure vacuum meter; 6. draft tube; 7. gas admittance valve; 8. escape pipe; 9. air outlet valve; 10. valve F; 11. well heaters; 12. circulation ducts.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, a kind of gasoloid gathering-device, comprises sales kit (SK) 1, airbag 2, heating arrangement 3, vacuum pump 4, pressure vacuum meter 5, draft tube 6 and escape pipe 8; It is inner that described airbag 2 is placed in sales kit (SK) 1, near upper surface; Described heating arrangement 3 is placed in sales kit (SK) 1 inner lower; Described draft tube 6 is placed in sales kit (SK) 1 side, is equipped with gas admittance valve 7 between draft tube 6 and sales kit (SK) 1, and described escape pipe 8 is placed in sales kit (SK) 1 opposite side, and it is connected with vacuum pump 4 by the air outlet valve 9 be arranged on escape pipe 8.Further, described heating arrangement 3 comprises well heater 11 and circulation duct 12, and well heater 11 is arranged on circulation duct 12.Further, described pressure vacuum meter 5 is arranged on sales kit (SK) 1, for measuring the pressure in sales kit (SK) 1.Further, described airbag 2 open side is equipped with valve F.
In sales kit (SK) 1, an airbag 3 is installed, the mouth of airbag 2 is provided with valve F, airbag 2 volume is greater than 1/2 of sales kit (SK) useful volume, require that airbag 2 has enough volumes and intensity, in sales kit (SK) 1 during draw samples, outside air enters airbag 2, and useful volume in sales kit (SK) 1 is reduced, thus easier extraction aerosol sample being kept even concentration.
During sampling, close gas admittance valve 7, open valve F 10 and air outlet valve 9, under the effect of vacuum pump 4, the air in sales kit (SK) 1 is drawn out of, and forms vacuum state in sales kit (SK) 1, closes air outlet valve 9.Then, open gas admittance valve 7, under atmospheric pressure effect, extraneous aerosol sample enters in sales kit (SK) 1.When the inside and outside pressure of sales kit (SK) is equal, close gas admittance valve 7, valve F 10, aerosol sample is collected to be kept in sales kit (SK) 1.Start well heater 11, gas heating in circulation duct 12 is also risen, cold air in sales kit (SK) 1 flows to bottom circulation duct 12, circulate in pipeline 12, go round and begin again, gas shuttling movement in sales kit (SK) 1, makes the aerosol particle in sample overcome gravity settling effect, is suspended in sales kit (SK) 1.
When being chemically examined by sample, opened by air outlet valve 9, with vacuum pump 4 from draw samples in sales kit (SK) 1, meanwhile, open valve F gradually, make outside air enter airbag 2, in sales kit (SK) 1, useful volume reduces, thus aerosol sample is kept the extraction of even concentration.
In sum, particle can be collected in a vessel with aerocolloidal form by the present invention, electrically heated mode is utilized to make air local heating in sales kit (SK), hot-air moves upward, cold air moves downward, form circulation, the aerosol sample in sales kit (SK) is made to overcome gravity settling effect, be in flow state, thus be suspended in sales kit (SK), take back laboratory with aerocolloidal form and analyze, and, airbag in sales kit (SK) can make the sample concentration extracted out in sales kit (SK) keep evenly, and equipment safety is reliable, simple to operate, easy to carry.
Describe the present invention by way of example above, but the invention is not restricted to above-mentioned specific embodiment, all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
