VOC Online Monitoring System

1.VOC Online Monitoring System product overview

VOC Online Monitoring System is an automatic detection system suitable for continuous real-time online monitoring of volatile organic compounds.

1.VOC Online Monitoring System Generation Background and Application Field

Volatile organic matter (VOCs) are important precursors for the formation of secondary pollutants such as fine particulate matter (PM2.5) and ozone (O₃), which in turn causes atmospheric environmental problems such as haze and photochemical smoke.With the rapid development of industrialization and urbanization in my country and the continuous growth of energy consumption, the frequency of heavy air pollution in the region is increasing, which seriously restricts the sustainable development of the social economy and threatens the health of the people.Therefore, in order to fundamentally solve the pollution problems such as PM2.5 and O₃ and effectively improve the quality of the atmospheric environment, the country actively promotes the pollution prevention and control of its key precursor VOCs.In recent years, Beijing-Tianjin-Hebei and surrounding provinces and cities have put forward clear construction requirements for the installation and networking of volatile organic compounds (VOCs) fixed pollution sources, unorganized emission monitoring facilities and alarm sensing devices exceeding the standard.

VOCs emission monitoring mainly involves the industries of petrochemical, organic chemical, pharmaceutical manufacturing, industrial coating, mechanical manufacturing, packaging and printing, electronic production, synthetic leather, coating and paint, clothing processing, furniture manufacturing, adhesives, shoes, and oil storage and transportation.At the same time, emissions have the characteristics of unorganized dispersion and organized fixed pollution sources, many types of pollutants, large concentration changes, and uncertain emission time.The TVOC automatic monitoring and alarm system can contact and provide data on TVOC total and key monitoring factor in various industries in real time, and connect online with the competent departments of the Environmental Protection Bureau to realize real-time monitoring of TVOC total emission reduction and pollution discharge charges.
