System Characteristics
The system uses the imported sampling pump to pump CO gas in the coal mill or pulverized coal bin through the sampling probe, and the sample gas is pre-processed, and the ZY300 infrared CO analyzer is used to complete the detection of the CO gas concentration. Any increase in CO concentration is a sign of an early fire alarm, and the system can make a corresponding alarm.
Technical characteristics
◎The sampling probe is maintenance-free, and the filtering principle is innovative, which fundamentally solves the clogging problem. The soot filtering capacity is less than 200g/NM3, and the maintenance is small.
◎The response time of the system is less than 10S, the response time of the instrument is less than 1.5S, the flow rate of the suction pump is large (6L/min), and the response time of the system is less than 10S, which is the fastest among similar domestic products. Effectively guide safe production.
◎System filtration accuracy≤0.1μm.
◎System reliability MTBF>3 years.
◎The product is cost-effective, and one system can realize simultaneous online detection of multiple components.
◎The system is fully dry filtering, the sampling is not distorted, and the analysis is accurate.
◎Fully automated system that is truly completely unmanned.
◎Intuitive display of calorific value, always observe the change of calorific value.
◎Real-time monitoring, fully automated touch screen control, truly online monitoring 24 hours a day.
