VOCs Online Alarm Monitoring System OSEN-VVOCs

In recent years, with the increasing severity of air pollution, haze has become a high-frequency topic of discussion among the public.VOCs (volatile organic compounds) are one of the components of smog particles.

According to calculations by the Ministry of Environmental Protection, as a global manufacturing powerhouse, ChinaThe annual emissions of VOCs reach over 30 million tons, ranking first in the world, and the anthropogenic VOCs emissions are rapidly increasing, which has a significant impact on regional composite air pollution. International experience has shown that controlling VOCs emissions is an effective measure to reduce haze and photochemical smog pollution.

Considering the domestic situationThe emissions of VOCs from anthropogenic sources are higher than those from natural sources, and are mainly concentrated in economically developed and densely populated areas. At the same time, the composition of VOCs from anthropogenic sources is complex, which not only affects the atmospheric environment but also poses direct or potential harm to human health. Therefore, monitoring and control of VOCs from anthropogenic sources in China is urgent.

Control volatile organic compoundsThe emission of volatile organic compounds (VOCs) is one of the effective means to reduce PM2.5, alleviate haze weather and photochemical smog pollution, and improve the air quality of regional cities.

1. Product Introduction

The VOCs online alarm monitoring system is applied to the detection of VOC gas concentration and the alarm of VOC gas concentration exceeding the standard. It can accurately detect the concentration of VOC gas and display the real-time concentration value of VOC gas on site, as well as sound and light alarms for exceeding the standard. It adopts wireless monitoring technology, grid fine distribution, and comprehensive monitoring of air pollution throughout the day to achieve comprehensive coverage of air pollution monitoring factors in the area. The standard signal output has the advantages of stable signal, high sensitivity and accuracy. The explosion-proof wiring method is suitable for monitoring the trend or interval of VOC concentration changes in ambient air and perimeter gas, and to monitor whether there are significant abnormal concentration exceeding problems in unorganized emissions or open areas. It is mainly used for leak warning and environmental monitoring, as well as factory pollution emission monitoring.
