Background technology
Aerosol is the microgranule that size is 0.001~100 micron, and by solid or liquid fine particle gas is disperseed and be suspended in The colloidal dispersion system formed in medium.Aerosol not only can on weather produce impact, and be air primary pollution source it One, easily lung is entered with breathing, blood is accumulated and enters in alveolar, it is detrimental to health.And these impacts and the extent of injury are all There is certain relation with the concentration of aerosol, therefore it is significant that quantitative sampling detection is carried out to aerosol.It is each at present Kind of aerosol sampling apparatus, have the shortcomings that sampling flow it is inaccurate with the sampling time, can not self-timing sample.
The content of the invention
The purpose of this utility model is to provide a kind of aerosol quantitative sampling detection means, to carry out to various aerosoies More accurately sample, improve sampling quality.
For achieving the above object, the technical solution of the utility model is:A kind of aerosol quantitative sampling detection means, including Sampling tube, aerosol concentration detection module, filter, mass flow controller, sampling pump, differential pressure pick-up, relay, control System and the first to the 5th connecting tube, described sampling tube one end is connected with the entrance of the aerosol concentration detection module, described The outlet of aerosol concentration detection module is connected by first connecting tube with the entrance of the filter, and the filter goes out Mouth is connected by second connecting tube with the mass flow controller entrance, and the mass flow controller outlet passes through institute State the 3rd connecting tube to be connected with the sampling pump, the sampling pump is connected with relay, the filter is by the described 4th, the Five connecting tubes are connected with the differential pressure pick-up, the differential pressure pick-up, relay, aerosol concentration detection module, quality stream Amount controller is also connected with control system.
In the embodiment of this utility model one, the aerosol concentration detection module be all kinds of aerosol concentration detectors, Various sampling of aerosol absorption bottles, dust aerosol sampler or bioaerosol sampler.
In the embodiment of this utility model one, the filter includes first being imitated along what aerosol flow direction set gradually Filter screen, silica dehydrator net, medium air filtration net, high efficiency particulate air and ultra high efficiency drainage screen.
In the embodiment of this utility model one, the mass flow controller is gas mass flow controller.
In the embodiment of this utility model one, the control system can pass through the start and stop of Control sampling pump, and energy Enough set sampling time, setting sampling flow, sampling number and sampling time interval.
In the embodiment of this utility model one, the control system is with industrial computer, PLC or single-chip microcomputer as core.
Compared to prior art, this utility model has the advantages that:
1st, in compared to conventional sampling of aerosol, sampling flow is adjusted using effusion meter and flow control valve Mode, this device reconciles required sampling flow using mass flow controller automatically, therefore sampling flow is more accurate steady It is fixed;
2nd, in compared to conventional sampling of aerosol, the sampling time is controlled using common timing mode, this dress Put by the way of the sampling of control system self-timing, therefore the sampling time is more accurate.
