Abstract

The invention relates to a non-dispersive ultraviolet multi-function measuring instrument for SO2, NO and NO2. The objective of the invention is to provide a non-dispersive ultraviolet measuring instrument for SO2, NO and NO2, wherein the instrument includes light sources and first to third detection mechanisms, and amounts of SO2, NO and NO2 in exhaust gas are measured simultaneously and accurately by utilizing one of the light sources of the instrument. A Perma pure dryer is disposed at the front end of a measuring unit and is a structure minimizing water interferences, thus improving measurement precision and durability.

Description

technical field [0001] The present invention relates to the measurement of SO contained in flue gases from chimneys using non-dispersive ultraviolet light 2 , NO, NO 2 Quantitative devices, in more detail related to non-dispersive UV SO, constructed in such a way as to prevent moisture interference and contamination, in order to carry out continuous measurements 2 , NO, NO 2 Measuring instrument pre-processing technology. Background technique [0002] With the progress of industrialization, the number of factories increases, and the number of chimneys also increases. The exhaust gas discharged from the chimney is considered to be a major cause of environmental pollution, so it is particularly important to measure and analyze the composition of the exhaust gas in order to reduce the exhaust gas emitted from the chimney. Harmful components contained in exhaust gas. On the one hand, currently used chimneys are mainly fueled by fossil fuels such as coal, petroleum, liquefied...
