Abstract

The invention belongs to the field of gas analysis and relates to a portable NH3 and HCl analysis system for comparison monitoring. The portable NH3 and HCl analysis system comprises a portable heating and sampling probe, a tracing heat pipeline and a portable analysis unit, wherein the tracing heat of a whole sampling analysis process of the portable NH3 and HCl analysis system is 220 DEG C and gas sampling temperature is higher than a acid dew point of a flue gas to be detected; the portable analysis unit comprises a temperature control unit, a high-temperature pre-treatment box, an oxygen analysis module, an NH3 and HCl analysis module, a data acquisition and control unit and a man-machine exchange unit. The analysis system has the characteristics of small interference, rapid speed, high sensitivity and high measurement precision, and field comparison monitoring work is extremely convenient to realize.

Description

technical field [0001] The invention relates to the field of gas analysis, in particular to a portable NH for on-site comparative monitoring of waste incineration flue gas CEMS 3 , HCl analysis system. Background technique [0002] Environmental protection is a basic national policy. There is a great demand for waste incineration in China, and the proportion of waste incineration in my country's cities has been steadily increasing. However, waste incineration flue gas is discharged into the atmosphere, causing great pollution to the air. The key technology for process control of waste incineration flue gas treatment is to use incineration flue gas CEMS for incineration flue gas treatment control and real-time monitoring of emissions. It is related to the national standard: incineration flue gas CEMS must conduct on-site comparative monitoring. Currently, the NH in the incineration flue gas 3 , HCl comparison detection method mainly adopts "Ion Chromatography for the Dete...
