Abstract

The invention provides a VOC (Volatile Organic Compounds) online monitor which comprises a data processing system and a monitor box which are in mutual communication connection; the monitor box comprises a box body, an input end, a trapping device used for collecting and finally precipitating a sample concentration and a hydrogen flame ionization detector used for inputting a collected sample intoa chromatographic column, monitoring the sample and outputting data. The VOC online monitor provided by the invention is an instrument which can analyze high-concentration total volatile organic compounds and low-concentration total volatile organic compounds at the same time and has the monitor concentration range of 0.5-1000ppb; is suitable for being applied to simultaneous detection of high-concentration and low-concentration waste gas emission, has the automatic correction function and can perform real-time monitor and remote fault diagnosis and maintenance in a running state of an FID detector by adopting the FID detector with high sensitivity, wide linear range and strong stability; and can have very strong adsorption capacity to the organic compounds by adopting a trap with a semiconductor chilling plate and a heating device.

Description

technical field [0001] The invention relates to the field of gas on-line monitoring, in particular to a VOC on-line monitor. Background technique [0002] Volatile Organic Compounds (Volatile Organic Compounds), referred to as VOC. At present, the VOC online monitoring system is an integrated system that provides gas monitoring services for the environmental monitoring industry, and can realize online monitoring of the main components and total amount of organic waste gas. The online monitor adopts advanced only component analysis algorithm and FID technology to collect, process, analyze, store and upload real-time measurement data of gas through high-precision AD sampling, and monitor the total VOC concentration, main component concentration and total emission in real time quantity. However, the pre-treatment analysis methods used by the existing VOC online monitors include quantitative tubes + columns + FID detectors. These monitors have complex structures and can only m...
