Description

The detection method of pellet PM10 in room air
Technical field
The present invention relates to the detection field device of PM10 a kind of, especially a kind of intensity for detecting scattering light can with so that Detect the detection method of pellet PM10 in the room air of the concentration of particle.
Background technology
It is exactly filter membrane method to detect the most classical method of pellet, only needs an inhalable particles in the above method Thing cutting head, a pump and film frame and its filter membrane, after gathering hour sample, remove filter membrane and weigh, it may be necessary to The multiple samples of parallel acquisition, are re-weighed after constant temperature and humidity.There are the unbalanced defect of material change on filter membrane for this method.
The content of the invention
Insufficient existing for existing technology in order to overcome, the present invention provides pellet PM10 in a kind of room air Detection method, what detection method this method of pellet PM10 utilized in the room air is particle in surrounding air Object light scattering properties is unfolded.Detection scattering light intensity can with so that detection particle concentration.
The technical solution adopted by the present invention to solve the technical problems is:The present invention comprises the following steps, and A. prepares standard Laser detection pipe and standard scattering detection pipe, standard laser detection pipe and standard scatter the detection pipe air duct with connecting respectively Equipped with the intersection region detected;The intersection region of laser light scattering light and lasing light emitter incident ray is arranged on the zone of intersection detected In domain;The incident ray of two lasing light emitters is respectively perpendicular and parallel row in laser light scattering section;B. environmental gas is gathered;C. ring is detected PM10 concentration in the gas of border;D. dry decontamination residual air;Heated using lumen, it is logical to be discharged to circulation using cutter purification air Road;E. residual air is recycled.
At one preferably or alternatively in embodiment, step B by fine particle collector specifically, collect to be detected Environmental gas, and environmental gas is heated and/or diluted according to air conditions.
At one preferably or alternatively in embodiment, in step B specifically, the PM10 in isolating environment gas, passes through PM10 screening installations separate, and particulate matter of the diameter more than 2.5 microns is removed, and diameter is less than and is sieved equal to 10 microns by PM10 Optional equipment.
At one preferably or alternatively in embodiment, in step C, detect the PM10 scattering strengths in environmental gas and change For PM10 concentration, specially using signal processor, PM10 scattering strengths are converted into PM10 concentration.
At one preferably or alternatively in embodiment, in E steps, specifically, residual air body is discharged from circulation canal.
The invention has the advantages that this method utilize be in surrounding air particulate matter light scattering characteristic be unfolded.Detection Scatter light intensity can with so that detection particle concentration.
