Description
Technical field
The utility model relates to a kind of particle concentration checkout gear based on laser scattering method.
Background technology
Atmospheric Particulate Matter has become one of common important content of paying close attention to of society in recent years. Particularly recent months, Beijing, Deng Ge big city, Shanghai are polluted by serious haze, and therefore Atmospheric particulates have caused popular concern. The index of weighing particle concentration mainly comprises TSP (overall suspended pellet), PM10 (particle that aerodynamic size is less than 10 microns) and PM2.5 (particle that aerodynamic size is less than 2.5 microns). Because fine particulates produces very large harm to the health of human body, especially be less than the particle of 2.5 microns, PM2.5 is because volume is smaller, there is very large specific area, thereby easily adsorb noxious material, and these particles can arrive deep lung easily, thereby cause various PUD Ds, country has issued " ambient air quality " standard of new revision for this reason.
The detection method of particle concentration is mainly by weight method, micro oscillation sedimentation balance method, β ray method at present. Weight method measuring process complexity, needs professional person to operate; Micro oscillation sedimentation balance method and β ray method can realize automatic measurement, but can not detect in real time, and instrument is expensive.

It is a kind of simple and reliable that the purpose of this utility model is to provide, laser light scattering particle substrate concentration checkout gear with low cost, this device comprises air chamber, lasing light emitter, amplifier, electronic cutting unit, laser intensity detector, processor and display screen, described air chamber is connected with air inlet, gas outlet, described air inlet, position is in opposite directions located in gas outlet, described lasing light emitter is located at air chamber front, amplifier is located at air chamber rear, electronic cutting unit is connected with amplifier, laser intensity detector is connected with electronic cutting unit, laser intensity detector by the transfer of data detecting to processor, finally read by display screen.
Further, between described lasing light emitter and air chamber, be also provided with the prism for focusing on.
Further, described electronic cutting unit is PM2.5 cutter. Electronic cutting unit, for separating of fine particle in described air sample, the particle that PM2.5 cutter makes diameter be greater than 2.5 microns is removed, and diameter is less than and equals 2.5 microns by described PM2.5 cutter.
Adopt the beneficial effect of this technical scheme to be: the method utilization be the principle that in air, particle can light scattering, can indirectly determine the concentration of particle by measuring scattering light intensity, utilize the measurement of laser scattering method to be subject to the impact of granular size, by determining number concentration and the big or small mass concentration that can calculate particle of particle, simple in structure, and can realize Real-Time Monitoring.
