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 monitoring points, not only the cost is high, but also the maintenance cost is very expensive. How can we develop a set of vehicle-mounted mobile devices and configure a The atmospheric environment PM2.5 monitoring device used in engineering construction can carry out mobile environmental monitoring according to the degree and demand of environmental pollution, which will greatly reduce the cost of atmospheric environmental monitoring

Embodiment

[0018] Embodiment: a kind of monitoring method that is used for the atmospheric environment PM2.5 monitoring device of engineering construction 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 , ...

Abstract

A monitoring device for particulate matter in the atmospheric environment used in engineering construction, characterized in that the device includes a dust equipment chassis (1), a light-receiving element (2), a receiving plate (3), a scattering plate (4), and a light-emitting element ( 5), the first exhaust pipeline (6), the second exhaust pipeline (7), the first fan motor (8), the second fan motor (9), the first exhaust port (10), the second Exhaust port (11), first exhaust channel (12), second exhaust channel (13), first air inlet (14), second air inlet (15), first gas extraction port (16) , the air supply channel (17), the second gas extraction port (18), the gas distribution channel (19), the particle retainer (20), the data acquisition storage system and the power supply system. The instrument can meet the self-cleaning function of the equipment under the condition of PM2.5 heavy pollution. The concentration of PM2.5 can be measured independently, and the concentration of PM2.5 can also be measured on-board.

Description

technical field [0001] The invention relates to the fields of engineering construction and atmospheric environment protection, especially the field of highway engineering, and specifically relates to a monitoring device for particulate matter (PM2.5) in the atmospheric environment used in engineering construction. 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 e...
