Description
Technical field
The present invention relates to a kind of aerosol collection 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 analysis.So far
Untill, particulate matter can still be collected in a vessel in the form of aerosol without a kind of, and laboratory point is taken back from strange land
The method of sampling of analysis.
A kind of gas sampling bag can gather gaseous sample in bag, take back laboratory analysis, but for aerosol sample
Product do not apply to simultaneously, because the haulage time for having 2 ~ 3 hours after the spot sampling of strange land could be analyzed to laboratory, in this period
Interior, aerosol sample can produce sedimentation because of Action of Gravity Field in sampler bag in aerosol, be attached on sampler bag wall, it is impossible to satisfactionization
Room analysis is tested to require.
The content of the invention
For the deficiency present in prior art, the present invention provides a kind of aerosol collection device, can make aerosol
Grain thing sample overcomes gravitational settling to act on, in flow regime, so as to be suspended in sales kit (SK), in the form of keeping aerosol.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of aerosol collection device, including sample
Case, airbag, heater, vavuum pump, pressure vacuum meter, air inlet pipe and escape pipe；The airbag is placed in inside sales kit (SK), is leaned on
Nearly upper surface；The heater is placed in sales kit (SK) inner lower；The air inlet pipe is placed in sales kit (SK) side, in air inlet pipe and sample
Intake valve is equipped between product case, the escape pipe is placed in sales kit (SK) opposite side, its by the air outlet valve that is arranged on escape pipe with
Vavuum pump is connected.Further, the heater includes heater and circulation duct, and heater is arranged on circulation duct
On.
Further, the pressure vacuum meter is arranged on sales kit (SK).
Further, the airbag open side is equipped with valve F.
The beneficial effects of the invention are as follows：1st, using the effect of atmospheric pressure, particulate matter can be collected in the form of aerosol
In a vessel, laboratory analysis is taken back in the form of aerosol.2nd, air office in sales kit (SK) is made using electrically heated mode
Portion's heating, hot-air move upwards, and cold air moves downward, and form circulation, the aerosol sample in sales kit (SK) is overcome gravity
Settlement action, in flow regime, so as to be suspended in sales kit (SK), keep aerosol state.3rd, the airbag in sales kit (SK) can make
The sample concentration extracted out out of sales kit (SK) keeps uniform.
4th, equipment safety it is reliable, it is simple to operate, be easy to carry.
Brief description of the drawings
Fig. 1 is the principle schematic diagram of the present invention.
1. sales kit (SK)；2. airbag；3. heater；4. vavuum pump；5. pressure vacuum meter；6. air inlet pipe；7. intake valve；8.
Escape pipe；9. air outlet valve；10. valve F；11. heater；12. circulation duct.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of aerosol collection device, including sales kit (SK) 1, airbag 2, heater 3, vavuum pump 4, pressure
Vacuum meter 5, air inlet pipe 6 and escape pipe 8；The airbag 2 is placed in inside sales kit (SK) 1, close to upper surface；The heater 3
It is placed in the inner lower of sales kit (SK) 1；The air inlet pipe 6 is placed in the side of sales kit (SK) 1, and air inlet is equipped between air inlet pipe 6 and sales kit (SK) 1
Valve 7, the escape pipe 8 are placed in the opposite side of sales kit (SK) 1, and it is connected by the air outlet valve 9 being arranged on escape pipe 8 with vavuum pump 4
Connect.Further, the heater 3 includes heater 11 and circulation duct 12, and heater 11 is arranged on circulation duct 12.
Further, the pressure vacuum meter 5 is arranged on sales kit (SK) 1, for measuring the pressure in sales kit (SK) 1.Further, it is described
The open side of airbag 2 is equipped with valve F.
One airbag 3 is installed in sales kit (SK) 1, valve F is installed on the mouth of airbag 2, the volume of airbag 2 has more than sales kit (SK)
Imitate the 1/2 of volume, it is desirable to which airbag 2 has enough volumes and intensity, and when extracting sample from sales kit (SK) 1 is interior, outside air enters gas
Bag 2, reduce dischargeable capacity in sales kit (SK) 1, so as to be easier that aerosol sample is kept to the extraction of even concentration.
During sampling, intake valve 7 is closed, opens valve F 10 and air outlet valve 9, in the presence of vavuum pump 4, sales kit (SK) 1
Interior air is extracted, and vacuum state is formed in sales kit (SK) 1, closes air outlet valve 9.Then, intake valve 7 is opened, in atmospheric pressure
Under effect, extraneous aerosol sample enters in sales kit (SK) 1.When the inside and outside pressure of sales kit (SK) is equal, intake valve 7, valve are closed
F 10, aerosol sample is collected to be stored in sales kit (SK) 1.Start heater 11, the gas heating in circulation duct 12 and on
Rise, the bottom of cold air direction of flow circulation duct 12 in sales kit (SK) 1, circulate in pipeline 12, go round and begin again, in sales kit (SK) 1
Gas circulation is moved, and the aerosol particle in sample is overcome gravitational settling effect, is suspended in sales kit (SK) 1.
When sample is chemically examined, air outlet valve 9 is opened, sample is extracted out of sales kit (SK) 1 with vavuum pump 4, meanwhile, gradually
Valve F is opened, outside air is entered airbag 2, dischargeable capacity is reduced in sales kit (SK) 1, so as to which aerosol sample is kept into concentration
It is uniform to extract out.
In summary, the present invention can be collected particulate matter in a vessel in the form of aerosol, and utilization is electrically heated
Mode makes the heating of air part, hot-air in sales kit (SK) move upwards, and cold air moves downward, and forms circulation, makes in sales kit (SK)
Aerosol sample overcome gravitational settling to act on, in flow regime, so as to be suspended in sales kit (SK), the band in the form of aerosol
Laboratory analysis is returned, moreover, the sample concentration that the airbag in sales kit (SK) can make to extract out out of sales kit (SK) keeps uniform, equipment safety
Reliably, it is simple to operate, easy to carry.
The present invention is described by way of example above, but the invention is not restricted to above-mentioned specific embodiment, it is all to be based on
Any changes or modifications that the present invention is done belong to the scope of protection of present invention.
