Gas analyzer calibration measurement apparatus and calibration measurement method thereof

Abstract

The present invention relates to a gas analyzer calibration measurement apparatus and a calibration measurement method thereof. The gas analyzer calibration measurement apparatus is characterized by comprising a standard gas supply system for calibration, a sampling system and a calibration gas circuit system, wherein the standard gas supply system for calibration comprises an air compressor, a zero air generator, a calibration gas supply device, a standard gas steel cylinder and a mixing bin, the sampling system comprises a gas sampling total pipe and a sampling pump, and the calibration gas circuit system comprises a plurality of three-way valves and a plurality of gas analyzers. According to the present invention, the standard gas supply system for calibration produces zero gas and mixing standard gas, the gases are input into the calibration gas circuit system to perform zero point and span point calibration on the gas analyzer in the calibration gas circuit system, the sampling system inputs the sampled sample gas into the zero point and span point calibration-completed calibration gas circuit system, and the calibration gas circuit system measures atmosphere gas pollutants in the input sample gas. The apparatus and the method can be widely used for atmosphere gas pollutant monitoring processes.

Description

technical field [0001] The invention relates to an instrument calibration measurement device and a calibration measurement method thereof, in particular to a gas analyzer calibration measurement device and a calibration measurement method thereof. Background technique [0002] At present, rapid economic development and energy consumption have brought great pressure to my country's atmospheric environmental governance. The problem of air pollution in my country is very serious. While suffering from severe particle pollution, the concentrations of ozone, sulfur dioxide, nitrogen oxides and carbon monoxide are also high. These gas pollutants will affect human health on the one hand, and also It will participate in atmospheric photochemical reactions, directly or indirectly causing an increase in the concentration of particulate matter in the atmosphere and other photochemical pollution. Therefore, accurate measurement of gas pollutants is very important for understanding the ch...

AI Technical Summary

Problems solved by technology

The conventional calibration method of gas analyzer is time-consuming, labor-intensive, inefficient, and takes up a lot of gas sampling time, so the measurement data of atmospheric gas pollutants in the sample gas has serious discontinuity
