Problems solved by technology

[0004] The above equipment is used to monitor CO and NO in the atmospheric environment 2 , SO 2 , O 3 In the process of calculating the air quality index for the concentration of five pollutants such as particulate matter and particulate matter, the parameter information of NO was not monitored at the same time, and the contribution of NO to total nitrogen oxides was ignored in fact.
At the same time, this monitoring method can only measure NO in the atmospheric environment 2 The total concentration, which contributes to the background NO 2 and NO from direct emissions from target sources 2 No distinction is made, so the above monitoring equipment will not determine the NO and NO emitted by the target pollution source 2 Complete emissions information for

Embodiment Construction

[0049] The embodiment of this application provides a kind of NO and NO 2 The monitoring method and its monitoring equipment are used according to NO and NO 2 The emission factors for NO and NO 2 complete emissions information.

[0050] Air pollution has always been a problem that plagues most countries in the world. There are many kinds of air pollutants. Typical air pollutants include carbon monoxide CO, nitrogen monoxide NO, and nitrogen dioxide NO. 2 , sulfur dioxide SO 2 , volatile organic compounds VOCs, ozone O 3 and particulate matter PM, etc. Therefore, to characterize air quality monitoring results, as many pollutants as possible must be measured simultaneously.

[0051] At present, typical monitoring equipment mainly monitors CO, NO 2 , O 3 , SO 2 and PM 2 .5 Calculate the local Air Quality Index (AQI) from the respective parameter information. However, in the process of calculating the air quality index, whether there is a relationship between pollutants, ...

Abstract

The embodiment of the invention discloses a monitoring method of NO and NO2 and monitoring equipment thereof for determining complete emission information of NO and NO2 according to the emission factors of NO and NO2. The method of the embodiment provided by the invention comprises that: the monitoring equipment acquires the appreciation values of parameters of a target pollutant, NO and NO2 emitted by a target pollution source, the appreciation values of parameters are the difference values between the parameters of the target pollutant, NO and NO2 emitted by the target pollution source and corresponding background parameters in the environment; according to the appreciation values of parameters of the target pollutant, NO and NO2, the monitoring equipment determines the emission factorsof NO and NO2 through a preset first formula; and the monitoring equipment determines the complete emission information of NO and NO2 according to the emission factors of NO and NO2.

Description

technical field [0001] This application relates to the field of environmental monitoring, in particular to a kind of NO and NO 2 Monitoring methods and monitoring equipment. Background technique [0002] Air pollution is an important problem plaguing most parts of the world, especially developing countries. There are various types of pollutants in air pollution. Some pollutants emitted by pollution sources do not directly pollute the air, but pollute the air through oxidation or combination with other components in the air, such as NO, volatile organic compounds, etc., pollution sources After the NO is emitted into the atmosphere, it will eventually be absorbed by the O in the atmosphere 3 Oxidation to NO 2 , so in areas far away from pollution sources, monitoring equipment cannot monitor the emission characteristics of NO. However, in areas close to pollution sources or with regional heavy nitrogen oxide pollution, NO is nitrogen oxides NO and NO 2 The most dominant fo...
