Description
Technical field
It the utility model is related to a kind of city atmospheric environment particulate matter acquisition technique field, more particularly to a kind of Multipoint synchronous
Low discharge ambient particle thing sampling apparatus.
Background technology
Air environmental pollution problem in town and country becomes increasingly severe in recent years, and ambient particle thing concentration also increasingly receives people
Concern.With the exploitation successively of many advanced analysis methodologies, the analysis testing level of environmental sample is greatly improved.But
It is that the collecting work of ambient particle thing sample is also limited be subject to all many conditions.Especially for research institution, it is necessary to gather a large amount of
Particulate matter space distribution information, this causes the enough particle sampling equipment of sampling operation needs, and sampling is of high cost and consumes
When effort.
Existing particle matter collection device, when TSP, PM10, PM2.5 sample of one point of collection, it is necessary to 3 kinds of cutting heads
And 3 samplers, when gathering the PM of three kinds of particle diameters of multiple points, it is necessary to which multiple cutting heads and multiple samplers, sampling take
With height, and it is not portable.
Utility model content
In view of the deficiencies of the prior art, the utility model proposes a kind of Multipoint synchronous low discharge ambient particle thing sampling cartridge
Put, the device is easy to use, and easy to operate and cost is low.Concrete technical scheme is as follows：
A kind of Multipoint synchronous low discharge ambient particle thing sampling apparatus, it includes stent 9, data collecting system 8 and multiple
Particle sampling device, each particle sampling device include particle sampling cutting head 1,2,3, sampling pipe 4, hole
Flowmeter 5, differential manometer 6, pressure sensor 7, diaphragm pump 10, the sampling cutting head, orifice flowmeter 5, diaphragm pump 10
It is sequentially connected with by sampling pipe 4, the sampling cutting head is fixed on by the sampling pipe 49 on the stent, described
Orifice flowmeter 5 connect the pressure sensor 7 and differential manometer 6, the orifice flowmeter 5, differential manometer 6 and pressure pass
Sensor 7 is connected with the data collecting system 8.
Further, the stent 9 is telescopic stent.
Further, the particle sampling cutting head 1,2,3 screws company with the sampling pipe 4 by internal and external threads
Connect.
Compared with prior art, the beneficial effects of the utility model are：
The Multipoint synchronous low discharge ambient particle thing sampling apparatus of the utility model, equipment when solving Multipoint synchronous sampling
The problem of quantity is more, mobile difficult, and of simple structure and low cost, stable operation, can different-grain diameter under the multiple points of synchronous acquisition
Aerosol sample under concentration, different levels distribution.Its data collecting system included can believe the particulate matter of multipoint acquisition
Breath is wirelessly transmitted to computer terminal, realizes real time monitoring.
Brief description of the drawings
Fig. 1 is the structure diagram of the Multipoint synchronous low discharge ambient particle thing sampling apparatus of the utility model；
Fig. 2 is that the Multipoint synchronous low discharge ambient particle thing sampling apparatus of the utility model realizes showing for Multipoint synchronous sampling
It is intended to；

Differential manometer, 7- pressure sensors, 8- data collecting systems, 9- stents, 10- diaphragm pumps.
Embodiment
The Multipoint synchronous low discharge ambient particle thing sampling apparatus of the utility model is made with reference to specific embodiment
It is further elucidated above.
As shown in Figs. 1-2, a kind of Multipoint synchronous low discharge ambient particle thing sampling apparatus, including TSP, PM10, PM2.5 tri-
A particle sampling device, stent 9 and data collecting system 8, each particle sampling device are cut including particle sampling
Head, sampling pipe 4, orifice flowmeter 5, differential manometer 6, pressure sensor 7, diaphragm pump 10, sampling cutting head, sharp-edged orifice plate flowmeter
5th, diaphragm pump 10 is sequentially connected with by sampling pipe 4, and cutting head 1-3 uses standard component, according to the difference of collection particle diameter, can be replaced
Different cutting heads, is fixed between sampling pipe 4 and cutting head 1-3 by threaded engagement, sampling cutting head 1-3 by sampling pipe 4
9 on stent, orifice flowmeter 5 is connected with pressure sensor 7 and differential manometer 6 by signal wire, orifice flowmeter 5, differential manometer 6
It is connected with pressure sensor 7 with data collecting system 8 by signal wire.
Stent 9 is telescopic stent, its support feet is scalable, so as to adjust height of sampling.
The Multipoint synchronous low discharge ambient particle thing sampling apparatus of the utility model can be distributed Multipoint synchronous sampling, and data are adopted
The data of each sampling apparatus collected by radioing to computer terminal, are realized synchronized sampling by collecting system.
