Abstract

The invention discloses an automatically-calibrated plug-in on-line gas analysis system which comprises a light emitting / receiving device (1), a measuring probe (12) and a calibrating device, wherein the calibrating device comprises a sample pool (2), a light reflecting device (3), a lifting device and a standard air source (11), the sample pool (2) and the light reflecting device (3) are fixed inside a calibrating device shell (6) through the lifting device, the sample pool (2) and the light reflecting device (3) extend into a pipeline (19) through the lifting device and are placed on a light path, the light reflecting device (3) is positioned at the rear end of the light path of the sample pool (2), and the sample pool (2) is provided with an air inlet pipe (4) and an air outlet pipe (9) leading to the outside of the calibrating device shell (6). The device is simple, and the calibrating device can not be corroded by smoke gas and can reliably work for a long time; and the device can carry out real-time on-line automatic calibration.

Description

technical field [0001] The invention relates to a plug-in online gas analysis system, in particular to a plug-in online gas analysis system with an automatic calibration function. Background technique [0002] The plug-in online gas analysis system is different from the traditional extraction sampling method gas analysis system. It does not require sampling and gas pretreatment process, overcomes many defects of the traditional extraction sampling method gas analysis system, and has the advantages of simple structure, stability, fast measurement and high precision. High, low operation and maintenance costs and other advantages, more and more widely used in environmental monitoring, industrial process analysis and other fields. The plug-in online gas analysis system can be realized by using various absorption spectroscopy techniques such as differential optical absorption spectroscopy (DOAS) technology and tunable semiconductor laser absorption spectroscopy (TDLAS) technology...
