Abstract
(EN)
A coal mine polar gas infrared detection device and a detection method therefor. The detection device comprises an intra-housing central processing unit (3) respectively and electrically connected to a power source (2), a light source (4), a detector (6), an annunciator and indicator light (9), an input/output module (8) and a data collection and storage module (7), wherein the power source (2) is further electrically connected to a power switch (11) and a power interface (12), and the input/output module (8) is further connected to a computer communication interface (10); the data collection and storage module (7) is further electrically connected to the detector (6); and a gas cell assembly (5) which is provided with a mobile window plate (27) and is fixed on the device is arranged between the light source (4) and the detector (6). A manual or automatic vacuum gas cleaning structure of a gas cell and a detection method therefor achieve a manual or automatic vacuum gas cleaning function of the gas cell, save gas cleaning of N2 gas, simplify gas cleaning procedures, save labour costs, eliminate manual errors, ensure the authenticity of the spectrum of a gas to be tested, and guarantee the accuracy of analysing the gas to be tested.
