Abstract

The invention discloses a full-automatic multichannel air passage switching atmospheric sampling device which can be widely applied to various atmospheric sampling systems. The full-automatic multichannel air passage switching atmospheric sampling device comprises an atmospheric sampler (1), a closed multichannel air passage switching device (4) and a control unit (5). The full-automatic multichannel air passage switching atmospheric sampling device can be widely applied to the field of detection of environmental gas. According to the working requirement, the communication or closing of each channel can be controlled in the sampling process of the atmospheric sampling device by switching the air passages, so that the collection time and sequence of all sampling passages can be controlled; and the full-automatic multichannel air passage switching atmospheric sampling device has the advantages of small volume, low energy consumption and the like.

Description

technical field [0001] The invention relates to a fully automatic multi-channel air path switching atmospheric sampling device, which is mainly used for collecting various atmospheric samples. Background technique [0002] With the rapid development of social economy, the process of human industrialization has also developed rapidly, but the accompanying problem is that a large number of "three wastes" are discharged, and various harmful gases in the air such as sulfur dioxide, nitrogen oxides and other harmful gases are harmful to human health. Constitutes an important threat, and the living environment of human beings is deteriorating day by day. The main function of the fully automatic multi-channel gas circuit switching sampling system is to collect the discharged gas, and through the experimental analysis of the collected gas, the composition and content of the collected gas can be obtained, so as to determine whether it is necessary The conclusion that the exhaust gas...
