Real-time online monitoring device of water volatile organic matter

Abstract

The invention discloses a real-time online monitoring device of water volatile organic matter, and belongs to the field of environmental protection, and particularly relates to water volatile organicmatter online monitoring. By means of the real-time online monitoring device of the water volatile organic matter, automatic sampling can replace existing manual field sampling, the field automatic purging cold trap trapping heat analyzing process replaces the laboratory manual operation trapping heat analyzing process, and the automatic online purging preprocessing, automatic inlet sample analyzing and data uploading and saving can be realized. According to the technical scheme, the real-time online monitoring device comprises an automatic sampling, sealing and calibrating module, an online water removal module and a cold trap trapping high-temperature analyzing module. The automatic sampling, sealing and calibrating module, the online water removal module and the cold trap trapping high-temperature analyzing module are sequentially communicated. The automatic sampling, sealing and calibrating module is connected with a sampling pump. The sampling pump analyzes and monitors a sample through the cold trap trapping high-temperature analyzing module after the sample is dried through the online water removal module. The real-time online monitoring device can be widely applied to the field of environmental protection.

Description

technical field [0001] The invention discloses a real-time on-line monitoring device for volatile organic compounds in water, which belongs to the field of environmental protection, and in particular relates to on-line monitoring of volatile organic compounds in water bodies. Background technique [0002] The existing monitoring of volatile organic compounds in water is mainly by manually collecting water samples on the water body site, packaging and storing them and bringing them back to the laboratory for chromatographic analysis. This monitoring method will inevitably cause inaccurate data due to the volatility of the monitoring factors. ; In addition, the on-site sampling is brought back to the laboratory for analysis, which has poor timeliness and cannot respond to changes in water quality in a timely manner; finally, the current monitoring method requires manual participation and cannot achieve the effect of continuous online monitoring.
