Embodiment Construction

[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] like Figure 1-Figure 5 Shown, a kind of atmospheric environment quality detection method of the present invention, this method comprises the steps:

[0032] S1: Move the gas collection device to the place where it needs to be collected, and unscrew the threaded pipe to the required height according to the height of the gas to be collected;

[0033] S2: Turn on the two air pumps of the gas collection device in S1, and then realize the evacuation of the gas in the inner tube body and the gas in the cavity surrounded by the inner tube body and the outer tube body;

[0034] S3: Open the control valve of the gas collection device that has been evacuated in S2 to realize the suction and storage of high-level gas into the gas storage cylinder; ...

Abstract

The invention relates to the technical field of environmental detection methods and particularly relates to an atmospheric environment quality detection method. The method comprises the following steps: collecting gas, transferring the gas to a to-be-collected site, and rotating a threaded pipe to a required height according to the height of to-be-collected gas; turning on two air pumps of a gas collection device, and completely exhausting the gas in an inner pipe body and the gas in a cavity formed by surround of the inner pipe body and an outer pipe body; opening a control valve in the vacuumized gas collection device so as to suck and store the gas at a high level into a gas storage bottle; and taking down the gas storage bottle, connecting the gas storage bottle to detection equipment,and detecting the gas in the gas storage bottle. According to the atmospheric environment quality detection method, the high-layer gas at different positions can be collected by adjusting the rotating height of the threaded pipe, and bottom-layer gas at different positions can be collected by selecting required air inlet joints, so that the collection range is wide, and the method can meet the atmosphere detection demands.

Description

technical field [0001] The invention relates to the technical field of environmental detection methods, in particular to an atmospheric environmental quality detection method. Background technique [0002] In order to effectively detect the atmospheric environment, it is necessary to use a sampler for sampling and detection. The atmospheric sampler plays a very good role in the detection of harmful gases in the air and the environment. [0003] The current samplers cannot collect gases at different heights at the same time, the collection efficiency is low, the range is limited, and the collected gases cannot be stored well. In view of this, the invention provides a kind of air environment quality detection method, and it has the following characteristics: [0004] (1) A kind of atmospheric environment quality detection method described in the present invention adopts the first gas collection mechanism and the second gas collection mechanism of inner and outer double-layer ...
