Abstract

An infrared imaging and concentration detection device and method for methane gas leakage, the device includes an infrared thermal imager and a laser methane detection module. The infrared thermal imager is used for infrared imaging of the required monitoring area to find methane gas leakage points; the laser methane detection module is aligned according to the leakage points found by infrared imaging, and measures the methane concentration. The laser methane detection module is embedded in the infrared thermal imager, the laser beam emission direction of the laser methane detection module is adjusted to be consistent with the optical axis direction of the infrared thermal imager, and the two communicate with each other to realize data interaction. The invention combines infrared thermal imaging technology for methane gas leakage detection with laser methane detection technology, and at the same time realizes non-contact large-area rapid search for methane leakage points and quantitative detection of methane gas concentration, which is more efficient than the existing single detection device and accurate quantitative comprehensive detection.

Description

technical field [0001] The invention relates to the field of gas detection, in particular to an infrared imaging and concentration detection device and method for methane gas leakage. Background technique [0002] In petrochemical and other industries, there are a large number of methane gas storage or transportation equipment with complex structures. Effective monitoring of the leakage of these equipment is an important prerequisite for ensuring safe production. At present, contact leak detection equipment is widely used, and the sensor of the equipment needs to be in contact with the detection target gas to detect the leakage. However, some leaking points may be leaking, but most of the potential leaking points have not leaked yet, so the operator must personally check and detect each potential leaking point, which is very inefficient and will cause harm to the health and safety of the inspectors. harm. The thermal imaging camera developed for methane gas leak detection ...
