1. Product Overview of VOCS Detection Station

The VOCS detection station is also called air quality detector and VOCS online monitor. The VOCS detection station has multiple functions such as gas sampling, filtration, real-time concentration display, wireless data upload, and environmental protection networking. The measurement results are more accurate and provide data for the environmental protection testing department. support.

1. Background and application fields

Volatile organic compounds (VOCs) are important precursors to the formation of secondary pollutants such as fine particulate matter (PM2.5) and ozone (O₃), which in turn cause atmospheric environmental problems such as haze and photochemical smog. With the rapid development of industrialization and urbanization in my country and the continuous growth of energy consumption, the frequency of large-scale heavy air pollution in the region is increasing, seriously restricting the sustainable development of social economy and threatening people's health. Therefore, in order to fundamentally solve pollution problems such as PM2.5 and O₃ and effectively improve the quality of the atmospheric environment, the country actively promotes the prevention and control of pollution from its key precursors VOCs. In recent years, the Beijing-Tianjin-Hebei region and surrounding provinces and cities have strengthened online monitoring of volatile organic compound emissions from key industrial sources, and installed and networked online monitoring facilities for fixed pollution sources of volatile organic compounds (VOCs) in key industries, unorganized emission online monitoring facilities, and over-standard alarm sensing devices. Put forward clear construction requirements.

VOCs emission monitoring mainly involves petrochemical industry, organic chemical industry, pharmaceutical manufacturing, industrial coating, machinery manufacturing, packaging and printing, electronic production, synthetic leather, coatings and paints, clothing processing, furniture manufacturing, adhesives, shoemaking, oil product storage and transportation industry. At the same time, emissions have the characteristics of unorganized escape and organized emissions from fixed pollution sources, many types of pollutants, large concentration changes, and uncertain emission time. The TVOC automatic monitoring and alarm system can provide real-time data on the total amount of TVOC and key monitoring factors of various industries, and can be connected online in real time with the competent departments of the Environmental Protection Bureau to realize real-time monitoring of total TVOC emission reduction and sewage charges.
