The invention discloses a method and an instrument for monitoring and analyzing components of gypsum rain on line, belonging to the technical field of environmental monitoring. The online monitoring and analyzing method comprises the following steps: feeding paper, measuring the blank filter paper, collecting sample gas, measuring filter paper containing gypsum rain components, and calculating the mass concentration of the gypsum rain components in the sample gas. The online monitoring and analyzing instrument comprises a detection unit, a sampling unit and a transmission unit. According to the method and the instrument disclosed by the invention, the concentration of gypsum rain components in flue gas is monitored on line, and the emission of the gypsum rain components in the flue gas is reduced by taking measures, so that the environmental pollution is reduced. Moreover, the monitoring and analyzing method and instrument can achieve the functions of automatic collecting, monitoring, calculating and outputting, the sampling frequency is high, the measurement time is short, and the accuracy is high.
Description
technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a method and an instrument for on-line monitoring and analysis of gypsum rain components. Background technique [0002] For a long time, my country's sulfur dioxide (SO2) emissions have been around 20 million tons, ranking first in the world. In recent years, with the development of the national economy and the improvement of people's living standards, my country has begun to accelerate the control of environmental pollution. In September 2013, the State Council issued the Action Plan for the Prevention and Control of Air Pollution, requiring "speeding up the construction of desulfurization, denitrification, and dust removal renovation projects in key industries. All coal-fired power plants, sintering machines and pellet production equipment in iron and steel enterprises, and oil refining enterprises. Catalytic cracking units and non-ferrous metal smelting enterp...
