Description
SC-odor600 fixed source volatile organic gas online monitoring system consists of flue gas sampler, temperature pressure flow humidity detector, heating cable, analysis cabinet pre-treatment system, auxiliary gas source, gas analyzer, data acquisition and processing, data transmission, etc. SC-odor600 fixed source volatile organic gas online monitoring system, which can continuously monitor the concentration of various organic gases such as total hydrocarbons, methane, non-methane total hydrocarbons, benzene, toluene, xylene, etc. or other gas concentrations of VOCs components. As well as gas temperature, pressure, flow rate, humidity and other related parameters, as well as statistical emission rate, total emission and other parameters, and can effectively manage the acquired data.
Features
Fully consider the sample gas conditions, dew point and other factors, and design the pretreatment system in a targeted manner
Explosion -proof/non-explosion-proof type optional
Highly anti-corrosion design. All parts that come into contact with the sample (for example, piping, valves, pressure regulators, and flow meters)
Special leak-proof design of sealing components
Based on the design concept of anti-corrosion and anti-leakage to ensure long-term reliable continuous operation of the system
Anti -blocking design of sampling system based on automatic high-frequency and high-pressure back flushing method, reducing maintenance
Advanced system technology, stable and reliable, strong applicability
On the basis of meeting environmental protection requirements, it is economical and reasonable
The system design fully considers the characteristics of environmental protection, and can expand the measurement requirements to improve the utilization value of the system
The analysis method is consistent with the standard method, and the GC-FID method is used to detect
Maintenance -free design for continuous operation, automatic cycle operation after startup, true online analysis
Simultaneous online detection of components such as non-methane total hydrocarbons and benzene series
