Abstract

The invention relates to the technical field of VOCs (volatile organic compounds) detection, in particular to a device for automatically measuring a trace VOC component in atmosphere, which adopts a double-enrichment-tube alternate working mode for automatic measurement, can greatly shorten the sampling period and improve the real-time performance and reliability of data. The device includes a filtering mechanism, a first multi-way valve, a first enrichment pipe, a second enrichment pipe, an MFC flow meter, a gas pump, a second multi-way valve, a carrier gas outlet, a second two-way valve, a carrier gas inlet, a first two-way valve, a VOCs analysis column, a VOCs pre-separation column, an FID detector and a plurality of sets of communicating pipes. The filtering mechanism is communicated with the first multi-way valve through a communicating pipe; The first enrichment pipe is communicated with the first multi-way valve through the communicating pipe, the second enrichment pipe is communicated with the first multi-way valve through the communicating pipe, the MFC flow meter is communicated with the first multi-way valve through the communicating pipe, the air pump is communicated with the MFC flow meter through the communicating pipe, and the second multi-way valve is communicated with the first multi-way valve through the communicating pipe.

Description

technical field [0001] The invention relates to the technical field of VOCs detection, in particular to a device for automatically measuring atmospheric trace-level VOC components. Background technique [0002] In order to implement the "Environmental Protection Law of the People's Republic of China" and "The Air Pollution Prevention and Control Law of the People's Republic of China", prevent and control environmental pollution, improve environmental quality, and strengthen the control and management of fugitive emissions of VOCs. It stipulates the control requirements for VOCs material storage fugitive emissions, VOCs material transfer and transportation fugitive emission control requirements, process VOCs fugitive emission control requirements, equipment and pipeline components VOCs leakage control requirements, open liquid surface VOCs fugitive emission control requirements, And VOCs unorganized emission waste gas collection and treatment system requirements, pollution mo...
