DR-123A flue gas online automatic monitoring system Introduction: The DR-123A flue gas automatic quality control system can accept remote commands to provide known concentration standard gas to the flue gas online monitor (CEMS), and the difference between the feedback result and the standard gas value is tested by the monitor, which can prove the running status of the online monitoring equipment. and the reliability of monitoring data. It is an effective tool for environmental supervision departments to implement supervision functions. The standard gas of the quality control system is connected from the sampling head, which is a whole-process quality control, which can effectively check the dilution and adsorption problems caused by the sampling pipeline; the key links of the system are equipped with sensors, which can remotely know the amount of standard gas and the amount of standard gas. Information such as pressure and standard gas flow can effectively sense whether the standard gas is leaking and whether the quality control is effective. Features: 1. Remote control function: the equipment has two working modes, manual and automatic; all functions can be set remotely, and the quality control system software is used to realize the operation of equipment start and stop, spot check control, parameter setting and receiving spot check results; 2. Whole process quality control: The standard gas is connected from the sampling head and enters the monitor through the sampling pipeline, which is the whole process quality control; (different from the instrument quality control where the standard gas directly enters the monitor) 3. Timing spot check function: The timing table can be freely set, and a certain flow of standard gas is passed into the analysis room of the CEMS online monitor according to the time in the timing table, and the CEMS analysis data is received, and the analysis data is compared with the standard gas concentration. Upload, the data can be saved for 1 year; 4. Instant spot check function: You can receive remote instructions at any time and start the spot check function; automatically check the spot check results, automatically save the spot check records and upload them at the same time, and the records can be saved for 1 year; 5. The equipment can monitor the analysis results of the flue gas analyzer in real time, and upload the data that exceeds the standard to the quality control system and save it automatically. It can automatically screen out abnormal data, data distortion and other information, and provide corresponding suggestions. 6. Fully enclosed access control structure, password protection, can save 100 records of opening and closing doors; 7. Intelligent diagnosis: can remotely obtain information such as the amount of standard gas, pressure of standard gas, quality control flow, etc., and can automatically alarm when a fault occurs; 8. Power-off alarm protection function: The device is equipped with its own power supply. After a sudden power failure, it can automatically switch to the self-provided power supply, and the device returns to the standby state, and the instrument data will not be lost after the power failure. At the same time, the alarm will be sent to the background platform, and the power failure record will be saved; 9. Communication function: with RS-232, digital I/O, 4mA ~ 20mA and other interfaces. Technical parameter: Random check time points: 24 Standard nitrogen bottles: 1 bottle Standard SO2/NO gas bottles: 1 to 3 bottles Standard gas working pressure: 0.5MPa～9.8MPa Air tightness of piping system: ≤0.05MPa Standard gas flow range: 0L/min～2L/min Mean failure-free continuous running time (MTBF): ≥1440h/time Insulation resistance: >20MΩ Communication interface: RS-232 standard communication port Analog interface: 4mA～20mA Working power supply: AC220V±10%, 50±1Hz Working environment temperature: 0℃～40℃ Working environment humidity: ≤85%
