Features

Analysis cabinet’s housing is stainless steel which is adaptable to corrosive environment. Besides, cabinet is sealed to prevent from corrosive gas. Intelligent
heater is built inside to ensure normal functioning of the system when inside temperature approaches 8℃. Analysis system can be programmed to realize auto‐drain and auto zero calibration function. Online infrared biogas analyzer is the core part of the system. Gas molecules Like CO2、CH4 which are composed of different types of atoms have absorption spectrum in infrared range. Absorption
intensity observes Lamber‐Beer’s Law. Our product is on the basis of it. In addition, electrochemical oxygen sensor measuring module can be installed internally so as H2S Sensor. One single analyzer can measure up to 4 gas components. Our equipment can be applied to detect the concentration of landfill gas, biogas and CO2、CH4、H2S、O2 produced in the biogas generating process.

It is applicable to various kinds of environment. Through analyzing parameter change, it helps to judge and alarm in industrial process. Meantime, 4‐20mA DC output and digital alarm output interface are available.

Sampling gas pipe installation

 To avoid mechanical damage, it’s appropriate to lay     the sampling pipe and exhaust pipe along the             support frame or pipe chase.

•   If it is difficult to recycle the exhaust to process           pipeline, you can evacuate it in safe area.

  You can not apply in‐site air as zero gas which is       severely polluted. Collect clean air with extra pipe       line if it is so.

•   If it is in open area, there is no need to connect           extra pipeline to drain the water.


Electrical installation

•  Panel
   Power Consumption: 500Watt
   Power Supply: 230VAC, 50‐60Hz
   Power cord is led through power entrance to main      switch QF up end, cable model:RVV 3*1.5mm2

 Signal cable
    Apply cable model RVVP 8*0.75mm2 if it is                 4~20mA signal output. If it is digital alarm signal,         you should choose according to alarm component.
    There are 4 alarm cables in total. Connecting             terminal lies under the panel inside the cabinet.           Refer to instrument manual for specific wiring.

Operation

To ensure the pipeline is without leakage, check carefully after all installation work is done. Make sure that grounding work is done and power supply meets particular requirements.


Power on

Switch MCB and enter in warm‐up interface, then system starts to work. Close the cabinet door and tighten it with hexagon wrench. It takes 10min’s warm‐up time to enter in measuring interface.


Sampling

First close V5 and then open V2, V1 in sequence, rotate V5 gently eventually till the flow is 1.0L/min. sampling gas will flow into analysis panel, it will show the gas components reading after a few seconds.

Maintenance

Instrument maintenance

Signal drift will occur if the analysis instrument is regularly used. It contains automatic zero calibration function. If you need calibrate manually, please refer
to concerning chapter.


Pipeline maintenance

To ensure reliable functioning of the system, you should check the pipeline working condition regularly to make sure that there is no leakage and plugging.
You can judge the trouble through below:

•   If there is tiny flow or even no flow in the flow             meter, please check whether the process pipeline       pressure is normal first and check whether the           pipeline is choked. Special notice: This trouble will     also appear if exhaust pipe is choked.

   If there is a huge discrepancy between                       measurement result and experience. There may         be leakage occurring.


Filter core maintenance

You should replace the filter material regularly according to actual pollution condition. Cut off sample gas valve and exhaust valve before replacing. To ensure tightness, lock cabinet door after replacement.


Drain

In cold weather condition, make sure there is no frost in drain 


Shipment and storage

Gas analysis system is highly sophisticated equipment. You should pack with wooden case stuffed with vibration‐absorptive material so that the glass will not be pressured against .Ensure the cabinet is in upright state in the process of shipment, anti‐moisture measures should be taken to protect electrical unit.
