Description
Technical field
The invention belongs to atmospheric detection equipment technical fields, in particular, in particular to a kind of β ray method Atmospheric particulates
The filter paper translating device of monitor.
Background technique
Atmospheric particulates are dispersed in solid-state or the general name of liquid particles shape substance in atmosphere.Grain-size of atmospheric particulate substance it is big
Small difference, is inhaled into and the position for being deposited on respiratory system is different, also variant to the harm of body.More delays greater than 5 μm
In upper airway, less than 5 μm are trapped in bronchiole and alveolar more.As people increasingly pay close attention to Atmospheric particulates to health
Harm, the monitoring technology of Atmospheric particulates is also more and more progressive.
Existing atmosphere particle monitoring means mainly have: β attenuation sensors, trace oscillating balance method and light scattering method.
Wherein, the particulate matter in atmosphere is mainly attached on filter paper by β attenuation sensors, then measures β ray after the filter paper
Loss, to calculate the mass concentration of particulate matter.Its specific measurement process is: specified blank filter paper is placed on the source β and detection
P1 point measurement between device passes through the Beta-ray intensity value of blank filter paper and saves, and then moves on to the filter paper in the region another
Specified P2 point carries out pumping sampling and leaves dust spot on filter paper, and the filter paper containing dust spot is moved back into the source β after sampling and is visited
The P1 point between device is surveyed, then measures its Beta-ray intensity value and saves, is had finally by being calculated with atmosphere particle concentration
The data of pass, to complete one-shot measurement；It carries out measure next time before, filter paper then needs paper feed certain distance.
According to above-mentioned measurement process, the specific region of filter paper needs to move back and forth between P1 point and P2 point, and mobile
Distance whether accurately directly affect the accuracy of testing result.Traditional filter paper move mode is by take-up pulley and to put band
Wheel rotates to realize, and determines mobile distance with the angle that belt wheel rotates is put by take-up pulley, due to different radii
Lower axle rotates the difference of circumference arc length corresponding to identical angle, causes each filter paper amount of movement different, is not able to satisfy
Permissible accuracy in production.Disclose that " a kind of β ray method PM10 is online application No. is the patent of invention of " 201010520126.3 "
The paper feed amount of filter paper is monitored and controlled in monitor form feeding device ", the main rotational angle using claw-pole motor, but this quantitative
Still not enough precisely.
