Greenhouse gas detection device based on TDLAS (tunable diode laser absorption spectroscopy) technology

Abstract

The invention relates to the technical field of gas detection, and discloses a greenhouse gas detection device based on a TDLAS technology, the greenhouse gas detection device comprises a laser probe, the lower part of the laser probe is fixedly connected with an emission rod, the upper part of the laser probe is fixedly connected with a pulley, the rear end of the pulley is movably connected with a slide rail, and a shell is attached to the upper part of the slide rail; according to the greenhouse gas detection device based on the TDLAS technology, through the relation among a laser probe, a transmitting rod, a pulley, a sliding rail, a shell, a control box, a transmission pipe, a receiving plate and absorption cotton, when the greenhouse gas detection device is used, the detection device can carry out component detection on internal greenhouse gas through the laser detection technology, and based on the TDLAS technology, the detection efficiency is greatly improved while laser detection is adopted. An internal laser emission rod can control the whole laser probe to move through a pulley, so that the whole device can be controlled to carry out distance and angle adjustment, and air in an external environment is collected and impurities are filtered through a receiving plate and absorption cotton.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a greenhouse gas detection device based on TDLAS technology. Background technique [0002] The emission of greenhouse gases causes the greenhouse effect, and greenhouse gases will increase the global temperature. While the earth absorbs solar radiation, it also radiates heat to outer space. When the radiation enters the atmosphere, it is easily absorbed by certain molecular weight, polar Absorbed by stronger gas molecules, and now the earth’s greenhouse gas emissions are increasing, which has a greater impact on the environment. Therefore, greenhouse gas detection instruments are needed to detect the air, so as to monitor greenhouse gas emissions. The existing TDLAS The technology is relatively accurate in gas monitoring and has high efficiency, which meets the requirements of environmental protection.
