Method for detecting concentration of carbon monoxide in air

Abstract

The invention discloses a method for detecting the concentration of carbon monoxide in air, and belongs to the technical field of air detection. The method comprises the following steps of: selectingan area to be detected, collecting air in the area to be detected at a first moment, and preprocessing the air to obtain the air to be detected; separating the carbon monoxide in the air to be detected by adopting a gas chromatographic method; introducing the separated carbon monoxide into a reaction device through a gas pipeline, and reacting the separated carbon monoxide with reactants under theaction of a catalyst to obtain a product; calculating the first concentration value of the carbon monoxide according to the product; repeating the steps mentioned above to obtain the second concentration value of the carbon monoxide in the area to be detected at a second moment; obtaining a deviation value according to the first concentration value and the second concentration value; and comparing the deviation value with a preset deviation value, and obtaining a detection result according to a preset strategy. The technical effects of ensuring the detection quality, improving the authenticity of detection data and reducing the detection pressure of personnel are achieved.

Description

technical field [0001] The invention relates to the technical field of air detection, in particular to a method for detecting the concentration of carbon monoxide in the air. Background technique [0002] Carbon monoxide is the most widely distributed and most abundant pollutant in the atmosphere, and it is also one of the important pollutants generated in the combustion process. Carbon monoxide exists in metallurgy, chemistry, graphite electrode manufacturing, household gas or coal stoves, and automobile exhaust. The main source of CO in the atmosphere is the exhaust of internal combustion engines, followed by the combustion of fossil fuels in boilers. When the concentration of carbon monoxide in the air reaches a certain value, if people live or work for a long time, it will cause harm to people's health. When the concentration is too high, it will even cause death or an explosion. [0003] Therefore, it is of great significance to detect the concentration of carbon mono...
