Description
Technical field
The utility model relates to PM2.5 detection technique field, relates in particular to a kind of PM2.5 pick-up unit.
Background technology
PM2.5 refers to that diameter in atmosphere is less than or equal to the particle of 2.5 μ m, also claims to enter lung particle.Although PM2.5 is the little component of content in earth atmosphere composition, it has important impact to air quality and visibility etc.PM2.5 particle diameter is little; contain that a large amount of poisonous and harmful substances and atmospheric residence time are long, fed distance is far away; therefore very large on the impact of health and atmosphere quality; in order to make accurately perception local air quality of the common people; to reduce it polluting the outdoor activity of weather or reminding it to take corresponding safeguard measure, PM2.5 is carried out to convenient, fast, real-time detection and just become the work being significant.
At present, the PM2.5 determination method that environmental administration of various countries extensively adopts mainly divides two classes: Manual analysis and automatic analysis, Manual analysis mainly adopts gravimetric method, and automatic analysis mainly comprises β rays method, micro-oscillating balance method, China mainly adopts gravimetric method to the mensuration of PM2.5 at present, its principle is mainly that extracting air passes through sampling thief, PM2.5 in surrounding air is trapped within on known quality filter membrane, calculates the concentration of PM2.5 according to the of poor quality and sampling volume of filter membrane before and after sampling.
Can see, the checkout equipment of existing PM2.5 generally has the shortcomings such as volume is large, power consumption is large, price is high, not portable.
Summary of the invention
The technical problems to be solved in the utility model is: have the shortcomings such as volume is large, power consumption is large, price is high, not portable in order to solve existing PM2.5 checkout equipment, the utility model provides a kind of PM2.5 pick-up unit to solve the problems referred to above.
The utility model solves the technical scheme that its technical matters adopts: a kind of PM2.5 pick-up unit, comprises
