Abstract

The invention belongs to the technical field of photoelectricity and micro electro mechanical systems, and relates to an air chamber structure, in particular to an air chamber structure of a nondispersive spectrum gas analyser. The air chamber structure comprises an air chamber inner shell, a filter core, an air chamber outer shell, a front cover, a rear cover, a transmitting end and a receiving end; the air chamber inner shell and the air chamber outer shell are of ring body structures, small holes are uniformly distributed on a circumference surface of the air chamber inner shell, and an inner diameter of the air chamber outer shell is larger than an outer diameter of the air chamber inner shell; through holes are opened on the front cover and the rear cover; and according to the novel straight air chamber structure provided by the invention, the affect on a calculating result of air concentration caused by pollution from extremely small number of dusts is greatly reduced, parallel light coincides with the empirical equation stated in the Beer-Lambert law, and the difficulty on norm algorithm of air concentration is reduced.

Description

technical field

[0001] The invention belongs to the technical field of optoelectronics and micro-electromechanical systems, and relates to a gas chamber structure, in particular to a gas chamber structure for a non-dispersive spectral gas analyzer. Background technique

[0002] For the detection of common toxic gases, especially inorganic toxic gases, special gas analyzers are generally used for detection, and gas analyzers based on the principle of spectral absorption are called spectroscopic gas analyzers here, which are a kind of gas analyzers with great development prospects. gas analyzer. Toxic and harmful gas analyzers based on spectroscopy Gas analyzers are currently mainly used in industries such as industry, agriculture, medical care, intelligent buildings, and analytical instruments for high-precision measurement of gas concentrations, such as supporting pollutant monitoring, automotive Exhaust gas analysis, gas and combustible gas detection, gas composition analy...
