Product Description

VOCs online monitoring system

 

Brief description:
VOCs online monitoring system discharge port: In order to adapt to the increasingly stringent emission standards and the basic effect of factory exhaust treatment to ensure production safety; enterprises need to detect the content of VOCS gas at the main pipe or discharge port before the exhaust gas enters RTO.

VOCs online monitoring system discharge port: In order to adapt to the increasingly stringent emission standards and the basic effect of factory exhaust treatment to ensure production safety; enterprises need to detect the content of VOCS gas at the main pipe or discharge port before the exhaust gas enters RTO.
VOCs online monitoring system For the determination of trace water content in gas, in addition to considering the various influencing factors mentioned above, the adsorption balance of water in the sample gas in the pipeline must also be considered. The proper handling of this problem must rely on repeated experiments, understand its changes and laws, and master the operating techniques in order to obtain accurate results. VOCs online monitoring system is an online instrument, and its components include sampling module, separation and purification membrane block, gas chromatography analysis module and data acquisition and transmission module. The system contains a gas chromatography separation device. Real-time online monitoring of VOCs can be achieved without manual intervention.

Product features:
1. Customized pretreatment: dehydration, cooling, drying, voltage stabilization, constant current, etc. of sample gas.
2. Applicable explosion-proof area: intrinsically safe explosion-proof composite instrument, meeting the requirements of strict use area.
3. Safety: when the concentration value exceeds the first-level preset alarm value, there will be an on-site alarm prompt; when the concentration value exceeds the second-level preset alarm value, it can be automatically interlocked as needed.
4. Module platform: the number of pretreatment levels and functions can be freely adjusted according to actual use conditions, and the adaptability range is wider.
5. Easy maintenance: one-button calibration/calibration, tool-free disassembly and maintenance, hot-swap replacement of sensor components.
6. Intelligent display: the range can be freely switched between PPm-VOL, and the display is more accurate.

Conventional practice:
1. Use PID photoionization principle: the characteristic is that the range is too narrow (0-10000PPm) and the data is accurate; but when encountering high-concentration components, it is easy to over-range and damage the sensor components, and the maintenance and replacement costs are too high.
2. Use FID flame combustion principle: the characteristics are fast detection response speed, accurate data, wide range, and wide gas adaptability; but the purchase and maintenance costs are high, it cannot be continuously tested online, it is easy to be damaged, and it is not suitable for sampling conditions.
3. Use infrared principle: the characteristics are fast detection response speed, accurate data, wide range (0-50000PPm), the sensor is not easy to be damaged, and the maintenance cost is low; but when encountering special gas components, it is necessary to verify in advance whether it can be measured. · In view of the above situation, Maanshan Xinmaibo Technology Co., Ltd. recommends the use of infrared principle and the use of German high-quality sensor Dynament/SST, which can control the accuracy at the PPm level; adopt pre-stage sampling pretreatment (electric pump + dust tar removal + water removal + constant flow + venting) + on-site numerical display, quickly respond to the total amount of VOCS in the pipeline, and extend the service life of the system to 3-5 years; data can also be transmitted to DCS/PLC/GDS through 4-20mA according to production needs to achieve overall automatic control.
