Against the backdrop of increasingly strict environmental regulations, ammonia escape monitoring has become a key link in controlling air pollution in industries such as thermal power, chemical, and waste incineration. Developed by Wuhan Shengnuo Instrument Technology Co., LtdeLAS-SThe series of environmental certification ammonia escape online monitoring in-situ extraction flue gas analyzer, with its innovative technical design and reliable monitoring performance, provides an efficient solution for industrial waste gas treatment.

1、 In situ extraction technology breaks through the bottleneck of monitoring

Traditional ammonia escape monitoring equipment requires extracting flue gas to an analysis cabinet for testing, which leads to problems such as condensation and adsorption losses in the sampling pipeline, resulting in measurement errors generally exceeding15%.eLAS-SThe series of innovations adopts in-situ extraction technology, integrating high-temperature sampling probes and detection tanks directly into the flue, and achieving high temperature resistance (up to)350℃）The ceramic filter membrane achieves gas pretreatment, avoiding ammonia loss during the sampling process. The actual test data shows that this technology controls the deviation rate between the measured values and the standard method within±3%Within, reach the Ministry of Environmental ProtectionHJ 533-2009Standard requirements.

2、 High precision detection capability escorts environmental compliance

Equipment equipped with tunable semiconductor laser absorption spectroscopy（TDLAS）Technology, through1653nmAccurate scanning of characteristic absorption peaks of ammonia molecules using wavelength laser, achieving0.01ppmUltra high resolution detection. InSCRIn denitrification process control, this precision can accurately capture ammonia escape mutations caused by catalyst activity attenuation, helping enterprises to stabilize the escape concentration within a certain range2ppmBelow, far below the national emission standards（8ppm）. some300MWApplication cases of coal-fired power plants show that ammonia consumption decreases after the system is put into operation18%Reduce nitrogen oxide emissions annually120Ton.

3、 Adapt to all working conditions to ensure stable operation

For harsh flue gas environments with high temperature, high dust, and strong corrosion, the equipment adopts a three-level protection design: the first level is titanium alloy sintered filter element filtration10μmThe above particles are captured by the second stage corona dust collector, and the third stage fluororubber sealing ring blocks corrosive gases. In the flue gas monitoring of sintering machine head in a certain steel plant, the system runs continuously360There was no malfunction in the sky, during which there were three sudden changes in flue gas temperature (from120℃Rise to280℃）The output data fluctuation is always less than±0.5ppm.

4、 Intelligent design improves operation and maintenance efficiency

The device integrates a self diagnostic module, which can monitor laser energy attenuation, optical path pollution, etc. in real time12Key parameter, when the detection accuracy decreases by more than5%Automatically trigger the calibration program. pass4G/5GWireless module, data can be synchronously uploaded to the environmental protection bureau's regulatory platform and enterprisesDCSSystem, supports mobile phonesAPPRemote viewing of historical curves and alarm records. A centralized monitoring project in a chemical industrial park shows that this design increases the frequency of inspections by operation and maintenance personnel from daily to daily3Reduce the frequency to weekly1Secondly, the annual maintenance cost has been reduced65%.

From precise monitoring to intelligent management,eLAS-SThe series of flue gas analyzers are redefining ammonia escape monitoring standards with technological innovation. Its environmental certification qualifications and full chain solutions not only help enterprises achieve standard emissions, but also“carbon peaking and carbon neutrality”Provide reliable data support for green transformation under the target.
