Background
At present, a laser gas analyzer mainly adopts two modes for analyzing sample gas, one mode is an in-situ laser gas analyzer, and the other mode is an extraction type laser gas analyzer. The in-situ laser gas analysis device generally adopts a double-flange correlation structural design, namely a laser transmitting unit is arranged on one side of a measured pipeline, a receiving sensing unit is arranged on the other side of the measured pipeline, and in order to ensure that the transmitting unit is in optical path butt joint with the receiving unit, the coaxiality of equipment installation is strictly ensured and complicated optical path adjustment work is carried out. In addition, in order to protect the optical window of the instrument from being polluted, compressed nitrogen is generally used as purge gas to be continuously introduced into the optical path of the instrument at present, and the consumption of nitrogen in one instrument is very large. When the sample gas containing a large amount of dust in the pipeline is measured, the intensity of the laser signal is seriously influenced due to the shielding of the dust on the laser signal, and even the situation that the receiving unit cannot receive the laser signal is caused, so that the measurement fails.
The extraction type laser gas analysis device generally extracts sample gas to the outside of a process pipeline through a sampling probe, then conveys the sample gas to the sampling probe through a pipeline for processing, and then enters an analysis gas chamber for measurement. Compared with an in-situ laser gas analysis device, the analysis device extracts sample gas to the outside of the flue for measurement, and reduces the on-site light path adjusting process; the sample gas is filtered before entering the analysis gas chamber, and the lens is not required to be protected by compressed gas; the sample gas entering the gas chamber is filtered, and the dust concentration in the flue does not influence the gas analysis. When high-temperature sample gas is extracted to the outside of the flue, gas components in the sample gas may react with each other to cause loss of gas components to be detected because the transmission temperature of the sample gas is generally lower than 250 ℃; low concentration, particularly highly adsorptive, gases will experience greater adsorption losses during transport due to the relatively long sample gas transfer lines.
Therefore, the existing in-situ laser gas analysis device and the extraction type laser gas analysis device on the market can not completely meet the requirements in actual production, and unnecessary manpower, material resources and financial resources are generated due to the inconvenience in multiple aspects and the occurrence of multiple accidents.
