In recent years, after the release and implementation of national air pollutant emission standards represented by thermal power, steel and other industries, ultra-low emission has become the direction of air pollution control. At present, the widely used monitoring instruments such as non dispersive infrared method and electrochemical method have prominent problems such as high detection limit, component interference and low concentration linearity difference, which can not meet the emission monitoring requirements and environmental management needs of lower concentration, stronger anti-interference ability and more components (SO2, no, NO2, etc.) under the new situation.
In order to monitor the ultra-low emission of waste gas from fixed pollution sources and obtain representative and accurate monitoring data, it is of great significance to put forward higher requirements for monitoring technology, monitoring instruments and standard methods.
Asp-3000 portable ultraviolet flue gas analyzer is a low concentration, high-precision and full component monitoring instrument independently developed by 澳门新京浦官网app., Ltd. (hereinafter referred to as Nanhuan Technology) after ten years of technology accumulation and precipitation.
The products can be widely used in waste gas emission monitoring of thermal power generation, steel, metallurgy, petrochemical, cement and other industries, as well as environmental monitoring stations, third-party testing institutions, universities and scientific research institutes.
Asp-3000 portable ultraviolet flue gas analyzer
Asp-3000 portable flue gas analyzer adopts the principle of UV-Vis differential absorption spectrum. The characteristic of this method is that the absorption cross section of gas molecules is divided into two parts: the differential absorption cross section (narrow-band absorption cross section) which changes rapidly with the wavelength caused by the gas molecules to be measured and the wide-band absorption cross section which changes slowly with the wavelength caused by the gas to be measured, interfering gas and dust particles. Through signal processing, the concentration signal of the gas component to be measured can be extracted, and the measured gas concentration can be obtained by using a specific algorithm.
The measurement shall not be disturbed by water vapor, Co, CO2 and other components;
Low detection limit and wide linear range;
Less affected by ambient temperature and vibration;
Dual range design, automatically switch the range according to the concentration value;
Configure micro thermal printer to support u disk data copy;
The whole process heat tracing of the sampling system can effectively avoid SO2 loss;
It can display the measured value curve of flue gas concentration in real time;
Support wif | data transmission and remote diagnosis.
Note: 1. The premise of the above performance indicators is that the ambient temperature, atmospheric pressure and flow are constant;
2. S02 and N0 ranges can be customized, and the maximum range can be up to 0-5000ppm and 0-1000ppm;
