Embodiment Construction

[0015] The present invention will be described below in conjunction with specific implementation examples.

[0016] Such as figure 1 As shown, the calibration gas sampling system for on-line detection of dioxins includes a calibration gas cylinder 1 (multiple as required) and a carrier gas cylinder 2. The carrier gas cylinder 2 and the calibration gas cylinder 1 are respectively connected to the Gas diluter 3, the gas diluter 3 can adjust the mixed type, mixed concentration and output flow between different standard gases and carrier gases; the outlet of the gas diluter 3 is connected to the time-of-flight mass spectrometer through the four-way valve 5 through the pipeline Instrument 7. The other interface of the four-way valve 5 is connected to the inlet of the pre-concentrator 4 through a pipeline, the outlet of the pre-concentrator 4 is connected to the gas chromatograph 8, and the gas chromatograph 8 is connected to the time-of-flight mass spectrometer 7. One end of the ...

Abstract

The invention relates to organic pollutant detection technology, and aims to provide a standard gas sample injection regulating system for dioxin online detection. In the system, a carrier gas cylinder and a standard gas cylinder are respectively connected to a gas dilutor through pipelines, the gas dilutor is used for regulating mixed species, mixed concentration and output flow of different standard gas and carrier gas, an outlet of the gas dilutor is connected with a four-way valve, other three joints of the four-way valve are connected to a time-of-flight mass spectrometer, a pre-concentrator and a flue gas sampling gun respectively, an outlet of the pre-concentrator is connected with a gas chromatograph, the gas chromatograph is connected with the time-of-flight mass spectrometer, and heat traced pipelines are arranged on the pipelines connected with all devices. Dioxin online detection target related compound standard gas can be transiently switched, and the shortcoming of incapability of continuously switching the standard gas for a long time is effectively overcome. Good temperature stability and gas transportation can be ensured, and data authenticity is maximally restored.

Description

technical field [0001] The invention relates to an organic pollutant detection technology, in particular to a standard gas sampling adjustment system for on-line detection of dioxins. Background technique [0002] Since the order of magnitude of dioxins is too low, online detection of dioxins is usually an indicator higher than the order of magnitude of dioxins that has a good correlation with the concentration of dioxins in real-time online detection to reflect the real-time detection of dioxins. emissions. Current studies have found that more suitable indicators are mostly chlorinated cyclic organic molecules such as chlorobenzene and chlorophenol, and these low-chlorinated substances have a good correlation with dioxins. However, in the detection process, it is first necessary to pass the standard gas to scan the appropriate wavelength, and then the calibration of the target compound and the collection of flue gas can be carried out. However, such organic compounds, esp...
