The invention discloses a VOCs online monitoring system based on integrated control. The VOCs online monitoring system comprises a pretreatment control panel, an online chromatographic instrument control panel, an FID signal control panel, an EPC control module and an integrated industrial personal computer, wherein the pretreatment control panel carries out temperature control through using a PCB, obtains a heating state in real time, and controls the flow direction and on-off of an air flow through an electromagnetic valve based on a switch control quantity; the online chromatographic instrument control panel is used for controlling a sample gas entering a chromatographic instrument to be maintained at a certain temperature, combining into a corresponding application form through a valve position state and controlling the chromatographic instrument to execute a corresponding service function; the FID signal control panel is used for controlling ignition and measuring range adjustment of a hydrogen flame ionization detector; the EPC control module is used for adjusting the carrier gas flow of each gas path system; and the integrated industrial personal computer is used for being connected with the modules, interacting data with the modules, acquiring real-time monitoring data and performing remote control. According to the VOCs online monitoring system, through an integrated control mode, the cost is reduced, remote troubleshooting and remote control are realized through the PCB-level industrial control system, the configuration is flexible, the feedback is timely, and the operation and maintenance performance of the system is greatly improved.
Description
technical field [0001] The invention relates to the technical field of atmospheric environment monitoring, in particular to an integrated control-based VOCs online monitoring system. Background technique [0002] VOCs are important precursors for the formation of fine particulate matter (PM2.5) and ozone (O3). Compared with the control of particulate matter, sulfur dioxide, and nitrogen oxide pollution, the weak management foundation of VOCs has become a shortcoming of atmospheric environmental management. At present, industries such as petrochemical, chemical, industrial coating, packaging and printing, oil storage, transportation and sales have become key sources of VOCs emissions. In order to protect the blue sky and further improve the ambient air quality, it is urgent to comprehensively strengthen the comprehensive treatment of VOCs in key industries; and the evaluation effect of treatment needs to rely on monitoring data to speak. However, various existing monitoring ...
