Embodiment Construction
[0027] Such as figure 1 As shown, the multi-point ambient air monitoring method of the present invention is used to perform roving detection of ambient air samples at multiple monitoring points through at least one detector, and each monitoring point communicates with the detection point through at least one sampling tube , and when the same round of detection is performed on the monitoring points distributed in different geographical locations in the monitoring area, the detected ambient air samples are taken from the same sampling time.
[0028] Including the following steps:
[0029] (10) Take ambient air samples at the same time at each point: start sampling and pumping from the end of each sampling tube away from the monitoring point at the same time, and obtain the ambient air samples at the same sampling time at each monitoring point;
[0030] (20) sequentially detect each ambient air sample: sequentially detect the ambient air samples at the same time at each monitori...

The invention discloses a multi-point environmental air monitoring method and system. Environmental air samples of all monitoring points at the same time point are obtained for detection and analysis, the detection result is accurate and timely, and backtracking and pollution source positioning are facilitated. The method comprises the following steps: (10) extracting ambient air samples of all points at the same moment; (20) detecting each ambient air sample in sequence; and (30) outputting a sampling time detection result. The system comprises a sampling channel corresponding to each monitoring point, each sampling channel is communicated with a detection gas storage chamber (8), and an outlet of the detection gas storage chamber (8) is communicated with a detector (10) through a detection pump (9); each sampling channel comprises a sampling probe (1), a two-way electromagnetic valve (2), a sampling gas storage chamber (3), a flow controller (4), a three-way electromagnetic valve (6) and a sucking pump (7) which are sequentially communicated through a sampling pipeline (5); and the detector (10) detects ambient air samples at the same moment of each monitoring point in each round.
Description
technical field [0001] The invention belongs to the technical field of environmental monitoring, in particular to a multi-point environmental air monitoring method and system. Background technique [0002] In order to effectively control environmental pollution and discover environmental pollution sources in a timely manner, more and more places, such as industrial parks, especially chemical industry parks, need to monitor the ambient air components at different points in the area, such as methane, non-methane total hydrocarbons, total hydrocarbons, Real-time sampling, detection and analysis of characteristic factors such as sulfur dioxide, so as to detect pollution in time and accurately locate pollution sources. [0003] Chinese invention patent application "multi-point gas monitoring device" (application number: 201711204959.7, publication date: 2018.3.9) discloses a multi-point gas monitoring device, which includes a selective sampling cylinder, multiple sampling connect...
