TDLAS gas detection apparatus comprising sonic standing wave

摘要

The present invention is a TDLAS gas detection apparatus including an acoustic standing wave and a gas detection method using the same. Specifically, in the process of generating a large amount of dust, such as in the cement manufacturing process, a detection device that collects dust in a certain area using acoustic standing waves and measures the concentration and temperature of gas by irradiating a laser other than the space where the dust is collected. And a gas detection method using the same.
