Problems solved by technology

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 dust monitoring device used in highway engineering 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 engineering construction atmospheric environment dust 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 gas collection port 16, so that the dust gas to be collected enters the dust equipment chassis 1, the scattering plate 4 disperses the dust gas, and the light-emitting element 5 emits light to cause light scattering of the dust gas. The concentration information of the gas is transmitted to the data acquisition and storage system, and the data can be collected and stored after the data is stable.

[0022] ④ After the data collection is completed, close the gas sampling port 16, open the second exhaust channel 13, the first air inlet 14 and the second air inlet 15, the dust gas enters the second...

Abstract

The invention provides a method for monitoring atmospheric environment dust in the engineering construction. The method is characterized by adopting a dust monitoring device for monitoring the atmospheric environment dust in engineering construction. The device comprises a dust equipment case (1), an acceptance element (2), a receiving plate (3), a scattering plate (4), a light emission element (5), a first exhaust pipeline (6), a second exhaust pipeline (7), a first fan motor (8), a second fan motor (9), a first exhaust opening (10), a second exhaust opening (11), a first exhaust passage (12), a second exhaust passage (13), a first air inlet (14), a second air inlet (15), an air production opening (16), a data acquisition and storage system and a power supply system. The method is simple,has high measurement precision, and can achieve a self-cleaning function of equipment under the condition of dust heavy pollution, and can be used for independently measuring the dust concentration and performing vehicle-mounted mobile dust concentration measurement.

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 method for monitoring dust in the atmospheric environment of 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 environment monitoring point...
