The VOC online monitoring equipment of Jingxun can effectively detect the concentration of VOC in the exhaust gas. In the process of chemical industry development, a certain amount of VOC waste gas will be produced. A large amount of VOC waste gas will not only cause serious pollution to the surrounding environment, but also pose a serious threat to people’s life safety. Therefore, in the development of chemical industry, it is necessary to take measures to deal with VOC waste gas, in order to reduce the impact of VOC waste gas on the environment and people’s life.
On-line monitoring system for volatile organic compounds
There are two main treatment technologies of VOC waste gas: destruction and recovery. However, different technologies are used to treat VOC waste gas, and the results are not the same, and the requirements on the composition of VOC waste gas are also different. In the process of the actual selection of treatment technology, we need to choose according to the composition and treatment requirements of VOC waste gas, in order to provide a quality environment for people’s life.
VOC on-line monitoring system is a gas detection product used for real-time on-line monitoring of volatile organic compounds in the environment.
It is a professional volatile gas detector integrated product that integrates gas sampling, gas filtration, gas interference, flow control, real-time concentration display, wireless data uploading, environmental networking, local sound and light alarm, equipment linkage and other functions. This product is designed with professional three-guard design and can be used directly in the outdoors.
After active sampling, professional water removal, dust removal, drying and filtration, the VOC online monitoring system enters the professional gas chamber for UV lamp ionization detection. It has the characteristics of faster reaction speed, stronger anti-interference ability, more accurate measurement and long service life. Wireless HJ 212 protocol data upload can be seamlessly connected with the local environment monitoring platform; Due to its excellent performance and good performance, it can not only be used as organized or unorganized gas emissions of enterprises, but also provide data decision support for environmental monitoring and other departments.
VOC online monitoring system is composed of VOC gas analyzer based on PID technology principle, dehumidification filter, high performance drying pipe, vacuum sampling pump, wireless transmission module, rotor flowmeter, 24V power converter, circuit protection device.
The working principle is as follows: the power supply of the detector is 220V, which is converted to 24V power through the internal power converter for VOC detector, vacuum pump and wireless data module; The internal vacuum pump takes the initiative to draw the outside gas into the trachea, and after efficient dehumidification and dust removal, it is sent to the gas chamber of VOC gas analyzer for concentration detection. At this time, the detected concentration value will be displayed on the screen of VOC gas analyzer in real time. At the same time, through RS485 signal or wireless 212 protocol for remote data transmission. In addition, the VOC online monitoring system can also be used in conjunction with the fan, valve, spray system and other equipment in the factory, through the internal switch signal to achieve linkage. Gas exceed the standard immediately alarm, linkage equipment simultaneously start/close.
