Description
Technical field
The present invention relates to air monitering technical field, and in particular to a kind of air granule sampler.
Background technology
With constantly carrying out for global industry, environmental pollution is increasingly severe, and various air-borne dusts endanger the health of the mankind, in recent years, about two particulate matters of PM2.5 and PM10《Ambient air quality》It is used to evaluate and test air quality.Many researchs have proven to particulate matter can be damaged to respiratory system and cardiovascular system, cause asthma, pulmonary carcinoma, cardiovascular disease, birth defect and premature death.Clean air is that the mankind rely in one of essential condition survived.But, with China's industrialization and the high speed development of national economy, substantial amounts of harmful substance is discharged in air, makes air quality degenerate, and has had a strong impact on the daily life of resident.Accordingly, it would be desirable to air quality is monitored, to improve air quality.
Wherein, air suspended particulated（Also referred to as aerosol）It is one of important indicator of evaluation air quality.
Air granule sampler complex structure of the prior art, function imperfection needs further raising.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided a kind of air granule sampler for automatically adjusting adsorption net adsorption rate and air detection flow.
To realize the object of the invention, there is provided technical scheme below：Air granule sampler, including cylindrical sampling capicity bottle, it is arranged at the air inlet pipe on sampling capicity bottle top, the exhaustor for being arranged at sampling capicity bottom of bottle end and the particulate matter quality concentration sensor being arranged on the medial wall of sampling capicity bottle and particulate count concentration sensor, it is characterized in that sampling capicity bottle stage casing is provided with two-layer electronic absorption web plate, up and down two-layer electron adsorption web plate is spaced 15mm, adsorption hole is staggeredly distributed with the levels electron adsorption web plate, electron adsorption web plate connects single-chip microcomputer, the single-chip microcomputer connects display device, air inducing fan is provided with the air inlet pipe, micro-suction pump is provided with exhaustor.
Preferably, upper strata absorption web plate center is connected with rotary shaft, rotary shaft stretches out sampling capicity bottle connection motor by upper end, and lower floor's absorption web plate is fixedly connected with sampling capicity bottle inwall.
