Embodiment

[0018] Embodiment: a kind of highway engineering atmospheric environment PM2.5 monitoring method is as follows,

[0019] ① Close the first exhaust channel 12, the second exhaust channel 13, the first air inlet 14, the second air inlet 15, the first air outlet 10 and the second air outlet 11.

[0020] ② Turn on the data acquisition system and power supply system.

[0021] ③ Open the first gas collection port 16 and the second gas collection port 18, so that the gas enters the gas distribution channel 19 through the second gas collection port 18, and the gas distribution channel 19 is centrifuged to sieve the gas after removing PM2.5 to the particle retainer 20. Sieve the PM2.5 gas to the air supply channel 17, and send it to the dust equipment chassis 1 through the first gas collection port 16; the scattering plate 4 disperses the PM2.5 gas, and the light-emitting element 5 emits light to cause light scattering of the PM2.5 gas , through the receiving board 3, the concentratio...

Abstract

The invention discloses a highway engineering atmospheric-environment PM2.5 monitoring method. The method is characterized in that a PM2.5 monitoring device is used for highway engineering atmospheric-environment PM2.5 monitoring; and the device comprises a dust equipment case (1), a light receiving element (2), a receiving plate (3), a scattering plate (4), a light emitting element (5), a first air exhausting pipeline (6), a second air exhausting pipeline (7), a first fan motor (8), a second fan motor (9), a first air exhausting port (10), a second air exhausting port (11), a first air exhausting passage (12), a second air exhausting passage (13), a first air entering port (14), a second air entering port (15), a first air collection port (16), an air sending channel (17), a second air collection port (18), an air separation channel (19) and a particle retention device(20). According to the method, independent measurement of PM2.5 concentration can be carried out, and vehicle-mounted-mobile-type measurement of the PM2.5 concentration can also be carried out.

Description

technical field [0001] The invention relates to the fields of engineering construction and atmospheric environment protection, especially the field of highway engineering, and in particular to a monitoring method for particulate matter (PM2.5) in the atmospheric environment of highway engineering. Background technique [0002] The construction of expressways will inevitably have direct or indirect impacts on the environment to a certain extent, especially it will change the continuity and integrity of the existing natural environment and destroy the ecological balance of natural environmental protection. By installing various atmospheric environment monitoring probes and systems during the project construction process, the environmental pollution caused by project construction can be effectively supervised. But for linear projects like highway projects or railway projects, which are hundreds of meters away and obviously cover the entire line of atmospheric environment monito...
