The gas online monitoring system is a gas detection product that conducts real-time online monitoring of flue gas, exhaust gas and other gases from various fixed pollution sources such as boilers, chimneys, and pipelines; It is a standardized, modular and professional volatile gas detection system integration product integrating gas sampling, gas filtration, gas cooling and dehumidification, flow control, real-time concentration display, wireless data upload, environmental protection networking, local sound and light alarm, equipment linkage and other functions; It has the characteristics of faster response, stronger anti-interference ability, more accurate measurement, and longer life; Through wireless HJ212 protocol data upload, it can be seamlessly connected to the local environmental protection monitoring platform; The cabinet adopts a professional three-proof design, which can be used directly outdoors; The system can not only be used as organized or unorganized gas emissions within the enterprise, but also provide data analysis and decision support for environmental monitoring and other departments.
The gas online monitoring system is composed of flue gas and exhaust Gas Detectors, high-precision dehumidification and dust removal filters, long-life vacuum sampling pumps, rotameters, 24V power converters and circuit protection devices, wireless transmission modules (optional), etc. Its working principle is as follows: the product is powered by 220V, and after the internal power converter becomes 24V, it directly supplies power to the flue gas exhaust Gas Detector, Vacuum Pump and wireless data module; After the Vacuum Pump working inside actively sucks the external gas into the gas pipe, it is sent to the gas chamber of the flue gas and exhaust Gas Detector for concentration detection after being cooled down by efficient dehumidification and dust removal. The detected concentration value will be displayed on the screen in real time; At the same time, there are 4-20mA, RS485, constant switching output port or wireless 212 protocol for data remote transmission; In addition, the gas online monitoring system can be used through switching signals with fans, valves, sprinkler systems and other equipment in the factory. In addition, its monitoring data can also be received in real time through special supporting software, and can realize multi-channel unified management and quantity expansion. The stored data can also be queried at any time period, curve display, data EXCEL export, etc., so that the monitoring data is clear at a glance.
The gas online monitoring system is suitable for the harsh monitoring environment of high temperature, humidity, tar and dust, and continuously monitors NO, NO2, NOX, O2, CO, CO2, HCL, HNO3, acid mist, fluoride, odorous gas, VOC organic volatiles, benzene series and other gases in the organized ambient air.
